LED Manufacturers will Uplift the Technology Entry Level and Find New Applications in Hopes to Raise Profitability in 2015
For many LED manufacturers in 2014 has been a challenging year. A lot of manufacturers' performance in first and second half of the year was very polarized. Lighting market demands werewolf stronger than expected in the first half of 2014, leading to a period of LED supply shortages, Said Roger Chu, Director of Research LEDinside, a research division of trend Force. Despite the positive development, the industry which impacted by clients double booking and distributors rising inventory levels During second half of the year. Many manufacturers werewolf impacted by the cooling demands markets, and price competition as a result. Worth Noting, the emergence of Chinese LED manufacturers led to sliding LED product prices. Hence, best led grow light will raise entry technology levels and find new applications in hopes to raise profit ability in 2015th
LEDinside estimates globally 239 new MOCVDs werewolf installed in 2014. Some Local Governments will continue to issue subsidies in China Throughout 2015 THEREFORE, more than 170 MOCVDs are expected to be newly installed in China. Overall, LED manufacturers expansion projects depends on Local Governments subsidies, hence LED chip manufacturers will grow.
As Chinese LED chip manufacturers improve Their technology and scale up production capacity, China's LED chip production capacity has Increased from 27% in 2013 to 36% in 2014. In the past, Chinese LED backlight and lighting applications Largely relied on Taiwanese or international LED manufacturers , but this is no longer the case. Due to Chinese manufacturers package Increasing usage of domestic LED chips, prices are increasingly competitive, leading to Chinese manufacturers growing market share in the global LED industry.
Spurred by falling product prices, high LED lighting market demands have emerged. LED bulbs remain the main growth drivers for LED lighting products in 2015. Including LED bulbs, tubes and other light source products, Said Chu. THEREFORE, LEDs retail price and costs are oft the main factors taken into consideration.
Standard and mid-power LEDs with good C / P ratio oft meet thesis LED lighting products at lower price demands, for instance 3030 and 2835 LEDs have become mainstream on the market. Future LED grow lighting will continue to find better heat dissipation material, and use high driving currents to reduce the number of LEDs. Even COB LED has Gradually Attracted attention from lighting manufacturers. Besides lower prices LED, LED lighting manufacturers have therefore turned to focus Their drivers and other components, in hopes of designing solutions to lower total costs.

"We place a strong emphasis on doing what we can to improve the lives of our customers and employees. Our Small Business Program helps customers like Bluestar save money on electricity and natural gas bills Their, Allowing them to focus more time and resources of Their on providing services did benefit our communities. "
Still, it what the maintenance cycle of legacy lighting, along with poor light quality, did plagued the farm. "Before the upgrade, we were lighting some of the barn with old incandescent bulbs 100W, and did what just not adequate," Said Blue Star's Paul Moshimer, who handles day-to-day operations. "We were forever changing bulbs,: because theywere always burning out. We tried installing some halogen lights, thinking did would improve the situation, but expensive and Those Were They did not last very long, either."
MaxLite and National Grid engaged lighting consultancy Cadmus to design a new LED lighting system. Contractor Hickman & Sgroi handled the installation.
The project included the replacement of 75W incandescent fixtures with 37 28 MaxLite LED Vapor Tight linear fixtures in the stalls, storage areas, and work spaces. Eight halogen and compact fluorescent-(CFL) fixtures in the entryways werewolf Replaced with 45W LED flood lights.
The results are stunning in terms of quality and potential savings. "The barn is so much Easier to see in and work in," Said Moshimer. "The quality of the light is so much more even. It's been a wonderful addition to the farm."
The led plant grow lights products are rated for 50,000 hours of life. National Grid projects did the farm will use 150,000 kWh less energy over period did. The maintenance and energy savings are projected at $ 34,000 over the lifetime.

the whole solution of LED logo signs
LED logo signs act as a general guideline path lighting and landscaping in front of a group doing a particularly good building, a beautiful and stylish and innovative, identification signs, often play a decorative role icing on the cake, set decoration, guidelines, advertising and other functions as one of the logo signs, led high bay light manufacturers has become an important part of outdoor advertising.
Logo signs by morphological classification:
1. Horizontal: The entire length ratio of the horizontal comparison. Generally the entire surface are being used as logo signs. Generally on the wall of the small shops and large buildings can be seen.
2. Vertical: Vertical entire proportion is relatively long. Generally the entire surface are being used as logo signs.
3, the sudden shape: prominent on the wall of the building, except in the entire surface of the back or sides of the wall outside of the case, both sides are being used as an advertising vehicle identification plate. For example three sides signage.
4, ground cylindrical: cross-shaped mark on certain fixed structure on the ground, vertical-shaped, three-dimensional shape of the logo signs.
5, the roof: that set some fixed structure on the roof of a building and hung above or close to the plate-shaped cubic or magic of live logo signs.
Signage By Material:
A smooth logo signs: screen or board oily, very smooth.
2, luminous material identification signs: cards with luminous material (that is, we usually say the neon lights).
3. The quality acrylic logo signs: acrylic material made main board material. For example, "McDonald's quality acrylic signs"!
4, metal logo plate: Under no circumstances specified board, as the main material with a metal plate or text plate surface and metal as the identity of the main carrier.
5, the electro-optical board identification signs: luminous tubes with light-emitting diode or monochrome or color to achieve performance results. Light-emitting diodes and manifestations can be divided into luminous optic panels, LCD, LED, CRT, FDT other five species.
Identification card by using a mesh Category:
At different times: A, Lighting: For day and night use, the installation of in-house logo signs luminous tube or cast spectrometer installed inside and outside the installation of lighting logo signs and so on. B, without lighting: there is no single purpose were used day and night, without any lighting.
Place different: A, Interior: located in the interior, such as the direction of the arrows, and other indoor reception. B, outdoors: in all non-indoor space.
Different purposes: A, Commercial: generally refers to commercial purposes in order to achieve established. B, public: in public places, as announced to the public or to announce some news information.
Cities in the number of cars has increased several hundred vehicles a day, fewer road resources, rational distribution for traffic signs, increase traffic monitoring, one-way street, and the time period limit line so requires signage to remind people: from traffic signs in terms of Note. Convergence between the various transport facilities, the conversion is absolutely not missing signs.

seven principles of Buying LED lamps
1, the chip radiated power level difference:
Xiamen Sanan chip, for example, S-23BBMUP-C *******, chip size is 23X10mil, this core has four radiation power levels (@ 20mA), the higher the radiation power, making the led street light wholesale beads brighter.
D24 and D27 radiated power difference 8mW, ie, the same size chip, lamp beads made of different brightness, a lot of difference, you need to know the chip radiation power levels.
2, lamp beads scaffold difference:
There are currently on the market, aluminum frame, brass frame, copper, such as stents, the cheapest aluminum frame, copper bracket expensive, the price difference of ten times. Even the copper bracket, silver prices also have high and low points, the market is generally called a good stand, mostly made of silver-plated brass.
3, the chip size difference:
The chip size is typically reported is mil, if not high power measuring microscope, is generally difficult to distinguish, the brighter the greater the chip, we can compare the size of the chip area by calculating the chip, such as 23X10, the chip area is 230 square mil, is a good way to use the chip area of the chip size difference.
4, wire material differences:
Chip and bracket is complete with gold wire bonding method in electrical communication with the wire on the market today, two gold wire, gold wire is best, according to the thickness of the gold is divided 0.7,0.9,1.0,1.2 etc., the more gold thick, lower heat set, the longer the life, to ask what all the material and diameter gold wire.
5, the phosphor difference:
White light beads with blue chip plus ** phosphor made, the main points aluminate and silicate phosphors, aluminate outperforms silicate, aluminate is the most representative of YAG, YAG stable performance , low light decay, poor silicate their chemical stability, but the brightness is higher than the YAG, want a stable performance of the products, but do not be fooled so-called high-brightness, this is a big problem.
6. Glue the difference:
Phosphor is to glue and after stirring at the point on the chip, the glue is good or bad influence to the light fades and color drift, poor glue for a long time will be yellow, light is increased, the glue is jelly.
7, color separation, partial pressure and spectral specifications:
Separation: is the color temperature binned as 3200K-3350K is a file, regular packaging factory will provide the color temperature of BIN code, the smaller the better color temperature binning, color temperature binning small light source color to make good consistency .
Partial pressure: that chip voltage binning, such as 3.0V-3.15V, the light source is a series-parallel connection, the voltage binning control in less than 0.15V, uniform current distribution of such sources, will help improve the life of the light source.
Splitting: that led street lighting fixture beads brightness binning, sub-file or have lumens of light intensity binning used for lighting, preferably lumens bins. Recommend purchase LED, or in luminous efficiency based, high-efficiency products, energy saving, long life before.
These are a few principles purchase LED lamp beads, only by understanding the content, and do these terms in your contract orders, you will have the opportunity to protect their interests, otherwise, you must suffer, lamp beads price is the most seductive trap, sink once, the company has only closed leave.

The best way to solve the heat in the LED bulbs
LED bulbs fever how to do? LED will produce heat, a lot of people will think that LED is a cold light source, it only refers to the LED light-emitting principle only.
LED bulbs heat causes:
The reason is because the led high bay light supplier
of the added heat energy into light, and not all, but a portion is converted into heat, the electro-optical conversion efficiency of about 20 to 30%. That is about 70% of the energy is turned into heat.
Specifically, LED junction temperature is due to two factors caused by:
Internal quantum efficiency is not high, that is, when the electrons and holes recombine and generate photons are not 100%, often referred to as the "leakage current" PN area leaving the carrier recombination rate decreases. Leakage current multiplied by voltage is this part of the power, which is converted into heat, but this part does not account for the main component, because the internal photon efficiency is close to 90%.
Internally generated photons emitted to the outside of the chip can not be fully converted to heat and the last, which is the main part, because the current which is called an external quantum efficiency of only about 30%, mostly converted to heat up.
As previously mentioned, although incandescent light efficiency is very low, only 151m / W or so, but it almost all the electrical energy into light energy and radiate out, because most of the radiation is infrared, so low light efficiency , but it eliminates the problem of heat dissipation.
LED bulb cooling solution:
Solve the heat LED bulbs, mainly from two aspects, before and after encapsulation package, can be understood as LED bulbs LED chip cooling and heat dissipation. LED chip select and process heat primarily with the substrate and circuit related article describes temporarily. This paper describes the heat LED bulbs, because any LED lamps are made, so the heat generated by the LED chip always end by the lamp housing scattered into the air. Lei Yu Adams Lighting think if heat is not good, because the heat capacity of the LED chip is small, a little bit of accumulation of heat will make the chip junction temperature is rapidly increasing, if prolonged high temperatures in the state, its life will soon shortened. However, these calories can really guide the chip to the outside air, to go through a lot of ways. Specifically, the heat generated by the LED chip from its metal heat block out, go through the solder to the aluminum plate PCB, and then only by thermal plastic to aluminum radiator. So heat LED lamps hotel project actually includes thermal conductivity and heat dissipation in two parts.
However, LED lamp shell heat and the use of premises in accordance with the power level, there will be different options. There are several main cooling methods:
Aluminum fin: This is the most common way of cooling, aluminum fins as part of the housing to increase the cooling area.
Thermal plastic case: a thermally conductive material at the time of filling plastic injection molding, plastic housing increases thermal conductivity, heat capacity.
Air cooling fluid mechanics: air hydrodynamics use light shell shape, creating a convection air, which is the lowest-cost way to enhance heat dissipation.
Fans inside the led high bay light price housing reinforced with long life and efficient fan cooling: low cost, good effect. But the trouble is that some fans want to change, does not apply to outdoor, this design is more rare.
Heat pipe cooling technology: the use of a heat pipe heat pipe technology, the heat from the LED chip lead into the housing fins. In large lamps, such as street lights, etc. This is a common design.
Surface radiation heat lamp shell surface treatment do radiation heat treatment: radiation heat smear is a simple paint, radiant heat can be taken away from the lights the way the shell surface.

Several proposals of raising the heat sink level of LED lamps
LED lighting reliability (life) depends largely on the level of heat, so the heat level to improve one of the key technologies. Mainly to resolve the excess heat generated by the chip through the heat sink, cooling the body spread out, this is a very complex technical problems.
Here we are described as:
LED lamp power, which need to be considered led high bay light for sale dissipation, power LED requires cooling. Power LED at 100mA operating current means more light-emitting diodes. Our line is marked with reference to the United States as defined ASSIST Union, according to the existing two kinds of typical LED forward voltage 2.1V and 3.3V, ie input power 210mw and 330mw power than LED are LED, the device needs to be considered hot casual problem, some people may have different views, but proved to improve the reliability of the power LED (life), we must consider the power LED thermal problems.
LED cooling heat-related parameters related to the main parameters have thermal resistance, junction temperature rise.
Refers to the effective temperature and the thermal resistance of the device provides an external reference point temperature difference divided by the steady state power dissipation in the device quotient. It is said that the most important device parameters degree heat. At present, the power LED thermal resistance of the heat better ≤10 ℃ / W, domestic coverage of the best thermal resistance ≤5 ℃ / W, thermal resistance up abroad ≤3 ℃ / W, such as the power to do this level ensures that the LED life .
Junction temperature refers to the temperature of the LED semiconductor junction device main heating section. It is a manifestation of the LED device under operating conditions, the ability to withstand temperature. Improve the heat resistance has formulated plans to target the United States SSL. Chip and phosphor or high heat resistance, has now reached the junction temperature at 150 ℃, the phosphor at 130 ℃, basically have little impact on the life of the device will not. Description chip phosphor higher heat resistance, the lower the heat dissipation requirements.
There are several different temperature rise, we are talking about here: shell - environmental temperature. It refers to the LED device package (LED lamps can be measured to the hottest) temperature and the environment (in the luminaire plane, away from the lamp at 0.5 meters) temperature difference. It is a direct measurement of the temperature value, and directly reflects the LED device peripheral cooling degree, practice has proved, at an ambient temperature of 30 ℃, if the measured LED bulb is 60 ℃, its temperature should be 30 ℃ in this case basically ensures that the lifetime value of LED devices, such as the temperature is too high to maintain the rate of the LED light source will be greatly decreased.
LED lamps heat new problem:
With the development of LED lighting products, there are two new technologies: First, in order to increase the flux of a single tube, inject greater current density, as mentioned below, so that the chip generates more heat, the need for cooling. Second, a new package structure, with the LED light source power is increased, a plurality of power LED chips need to set package together, such as COB structure, modular lamps, etc., will generate more heat, need for more effective heat dissipation structure and measures, which gave the heat raised new issues, otherwise it will greatly affect the performance and life of LED lamps.
At present, the total thermal efficiency of LED lamps is only 50%, there are a lot of power to become hot. Secondly, LED high current density and modular lighting, etc. will produce more concentrated heat, need a good heat dissipation.
In order to improve the heat level we offer the following suggestions:
1), from the LED chip, it should adopt a new structure, new technology, to improve the LED chip junction temperature of heat resistance, heat resistance, and other materials, making the lower heat dissipation requirements.
2) reduce the thermal resistance of the LED device, using the new package structure, new technology, the choice of thermal conductivity, heat resistance, good new material, including the bonding between the metal material, such as phosphor blend, making resistance ≤ 10 ℃ / W or less.
3) reduce the temperature, try using a good thermal conductivity thermal material, the design requires good ventilation channels, spread it out as soon as possible so that heat, warming the requirements should be less than 30 ℃. In addition, to improve the heat dissipation modular lighting level should be on the agenda.
4), the way a lot of heat, such as the use of heat pipes, and of course good, but the cost factor to be considered in the design issues should be considered cost-effective.
In addition, led street lighting Manufacturer in addition to improve lighting efficiency, light requirements, appearance outside, to improve the heat level, the use of materials with good thermal conductivity, there were reports that some nanomaterials coated radiator, its thermal performance increase of 30 %. In addition, there must be better mechanical properties and sealing, cooling the body but also dust, LED lamps require a small temperature rise should be 30 ℃.
Here we are described as:

Green App for Earth Day Saves Energy: Light Bulb Finder
Switching to energy-efficient light bulbs is one of the fastest and easiest ways to conserve energy and protect the environment this Earth Day. Developed by Eco Hatchery, the free led street lighting fixture Finder mobile app enables users to decide which energy-efficient bulbs are right for their own homes and budgets. The app shows how much energy can be saved by replacing one or multiple bulbs and what the total carbon footprint improvement will be.
Named "Best Overall App" by the Environmental Protection Agency (EPA) in its Apps for the Environment Challenge, Light Bulb Finder is available as a free download on iPhone, iPad, iPod touch, and Android mobile devices.
Walking through the home or store aisle, app users get instant recommendations for energy-saving bulbs with the light quality and fit that mimics their traditional incandescent bulbs. For each recommendation, the app displays financial payback and environmental impact information, enabling users to make informed decisions. Bulbs can be purchased through the app or at local stores.
A typical household can save over $ 110 in annual energy bills by making the switch. That's money most homeowners would happily keep in the bank or spend on other things.
Changing just one more bulb, led street lights price spot or porch light, will have a positive impact. If every US household replaces one bulb, it would prevent 90 billion pounds of greenhouse gas emissions from power plants, the equivalent of taking 7.5 million cars off the road, according to the Union of Concerned Scientists.
Energy-efficient bulbs may cost more up-front, but the overall cost of buying and powering them is significantly less in the long run, plus they do not have to be changed as frequently. Compact Fluorescent Light Bulbs, or CFLs, last on average eight times longer than incandescent bulbs, and Light Emitting Diodes, LEDs, last 25 or more times longer.

The factors of influencing LED lamps life and how to purchase shell
LED downlight life factors
1. LED downlight cooling system: the current high-power LED light source emits white light flux reached only 100lm / w or so, in theory, only the energy into visible light nearly 1/3 majority of energy into heat energy. If the heat treatment of the poor lighting, high chip PN junction temperature, LED downlight chips will soon be corrupted;
2. LED downlight drive power: the problem is easily overlooked, is usually much larger than life led street light with solar panel chip driving power of life, often not bright LED downlights, upon inspection found that the chip is not damaged, but the drive power supply fault current, very good drive power life has more than thirty thousand hours;
3. LED chip quality downlights, LED downlights chip is the core component of the light source, lattice defects affect chip quality, the quality of the packaging process and phosphor.
Type LED downlight fittings
Generally divided into three categories:
1. Shell Kit (includes a housing, aluminum plates, screws, lens (Ceiling spotlights will be used, etc.), etc.),
2. Power (choose a good quality of power supply to note that efficiency, PFC value, whether there had been certified, the shelf life years, etc.)
3. The light source (a good source is the first formal chip packaging factory technical strength (the same chip manufacturers to do out of each quality is not the same, which is mainly technical issues 9, the quality of the light source (light decay contain source deviation color temperature, life, etc.)
How to choose the downlights shell
General household selection led downlight only stylish and elegant, and high cost. Take the price for, led downlights in the store more expensive, because the profits led downlight great buy on Taobao will save these intermediate links if you need to, you can go and see. At the same time, you can purchase appropriate housing, install their own; downlight housings domestic product technology has been very mature, and what quality problems do not exist, may be just dealing with some of the details as foreign, but domestic use is certainly not a problem . For downlight housings say, how to buy and buy downlight housing is very important, is one of the more important points: heat, heat transfer flux; we do not only choose pretty nice and ignore this.
Comments are the beginning of the lights in the town, copying the style of imitation frantic, many manufacturers simply take a camera, to the town lights Fair or domestic and international lighting exhibition "click" a few beautiful photos of lighting, you can go back and photograph gourd painting scoop to produce exactly the same product. However, is that in this short decade, many manufacturers awareness of IPR protection has become more enhanced. The simplest is the most common in the Light Fair exhibitors manufacturers have explicitly prohibited to take pictures of the guests.
Plastic shell heat dissipation downlights
Plastic radiator recently also attracted attention. Function reasonably good thermal conductive plastic materials are usually conductive features good information, in turn conductive plastic dysfunction, its thermal features certainly is poor. This is bound to the. Thus significantly metal than plastic, good thermal conductivity. In reality, too. Well, is not it certainly can not be used to make plastic radiator it? Not so! Recently published research on a variety of conductive plastic internationally, mostly in their information and general engineering plastics for the substrate, such as PP, ABS, PC , PA, LCP, PPS, PEEK and the like. Some metal oxide powder is then filled, carbon, fiber or ceramic powder made in plastic. For example, the polystyrene (PPS) and large particles of magnesium oxide (40 to 325 mesh) fusion can be made of an insulating form of thermal plastic. The thermal conductivity of its model range is 1-20 W / mK, some grades can reach 100 W / mK. This value is roughly 5-100 times that of traditional plastics, plastic thermal conductivity generally only 0.2 W / mK.
COB downlight enclosure cooling requirements
1. aluminum material better, try to form a thermal cooling effect in one, to achieve high efficiency thermal conductivity and heat dissipation
2. Multi-designed vents, and radiator fins peripheral conduction, convection air to achieve the outside row of LED's heat, while achieving the heat through the heat sink in order to achieve efficient cooling.
3. radiator over the wire, he shall be designed sewing equipment, wire and difficult to pull off, meet safety requirements.
4. Radiator structure surface processing as smooth burr-free, safe and not hurt the hand.
5. The shape of the radiator to be beautiful, light weight.
Ordinary SMD package device is different, stand cob surface light source is non-standard type, designed to stand directly related to the products of heat and light effects, the COB device design, design stand directly affects the life of the product and technology indicators. COB traditional products, between the chip and the heat of the aluminum layer of thermal insulation adhesive, is not conducive to the chip to heat, light efficiency is not ideal, but COB surface light source products directly placed on the chip aluminum thermal structure design more reasonable time optical design more reasonable, higher optical efficiency.
Zhongshan Guzhen Lighting Factory is half dragon LED downlight, LED ceiling light, COB downlight, COB downlight housings and accessories professional production and processing factories, innovation and development as the core, to provide customers with professional LED interior lighting solutions program mission to market demand, according to the application characteristics of different markets, combined with LED lighting to their strengths, developed a variety of energy-saving LED lighting applications, and has replaced the traditional lamp lighting products become mainstream in the relevant fields.
Slim LED downlight housing okay?
In order to pursue a more perfect people developed an ultra-thin LED downlight housing, regardless of form or function are superior. Slim LED downlight housing is the application of new LED lighting the traditional lamp based on the improvement in the development of products, comparing with the traditional downlight housing has the following advantages: energy saving, low-carbon, longevity, color is good, fast response. Slim LED downlight design more beautiful light, can reach to maintain the overall architectural unity and perfect installation, does not destroy the lighting setup, light hidden architectural interior light source is not exposed, no glare, the human visual effects, soft, uniform.
Currently, in the town, led street lighting Manufacturer need to spend 10 dollars, you can upload a lighting design drawings via the Internet, by intellectual property rights center quickly cover a virtual "time stamp", with the "timestamp" appearance design patent protection will have a say. Guzhen Technology Office 黄志桐 said, "In the past the appearance of patent applications almost a year, but with quick rights center, 15 days to be able to register a patent, intellectual property business has been more effective protection. Financial support is not really the most important government departments to help the largest enterprises, is not good business to do. "So, town lighting companies rights awareness crescendo, copying the style gone, many manufacturers want to change to create fake, play own brand.

6 home lighting problems that you need take more attention
PhD University of Texas Health Science Center endocrinologist Russell Reiter said, lighting a drug (Xiaobian Tucao: this analogy too hard, right, Ph.D.). Abuse lighting is a health hazard. Modern life has been inseparable from a wide range of led high bay light supplier, but surrounded by our lighting can also occur if the use of improper problems even adversely affect us. This is not an alarmist, modern home lighting and some issues that need our attention.
1, should pay attention to safety
Family life, safety should come first, which also requires us to purchase fixtures and accessories to choose a brand protection, product safety certification. There are security products, though the price is slightly higher, but the quality of clearance, is generally not a problem.
Here are some common certification mark, which China Compulsory Certification subject to compulsory certification, the most common.
Authenticate
2, try to choose a non-heavy metal fixtures
When selecting fixtures to try to choose a lamp free of heavy metals, such as mercury, cadmium, lead, heavy metals such is not easily degraded by microorganisms and has significant toxicity, a great impact on the environment, especially in energy-saving lamps contain mercury vapor, broken bulb can cause mercury vapor emissions, selection should be noted.
General specification of the products will eventually give indicators of heavy metals to tell consumers what the product contains heavy metals.

3, following the principle of proportionality
Home environment is the environment of our daily lives, so the lighting light should follow the principle of proportionality, indoor neither too bright nor too dark. The lighting is too bright for our eyes harmful; too dark indoor environments is prone to visual fatigue, while our emotions are likely to be affected.
Professor Randy Nelson Ohio State University, January 21 at the annual meeting of the American Neurological Section, said: Excessive exposure to light at night may lead to depression. In addition, light pollution can cause dizziness, irritability, depression, physical fatigue and other symptoms similar to neurasthenia.
4, natural lighting and artificial lighting combine
Home lighting should be combined with natural lighting and artificial lighting, can not all rely on lighting. Sunlight can kill harmful microbes in indoor air; can improve human immunity. Experts believe there are two hours a day of sunshine indoors is the minimum required to protect human health and development. Visible natural lighting is essential, home lighting should not stand in the sun outdoors.
5, choose energy-saving lamps
Average daily household lighting lighting time is not long, but the energy is still a need for attention indicators. Good performance of energy-saving lamps, although the initial investment in a large number, but in the future be able to benefit in the long run also in line with the requirements of environmental protection.
Now, because it is not saving incandescent lamp has become history, LED energy-saving because the ascendant, its fluorescent energy saving compared to incandescent lamps, as well as pushing the government and awarded the "energy-saving lamps" name known.
6, the light should be harmonized
Lighting should not be too diverse, so as not to endanger human health. If the contrast is too light colors, dazzling, not only bad for the eyes, but also interfere with the brain center of higher nervous function. Too much color, easy to produce light pollution, it is obvious example, in the disco light pollution is very serious, easy to eye discomfort. In addition, irrational light color also affect the visual development of children. A light color in the room is best not more than three kinds, it should harmonize between various colors.
Home lighting mainstream sources:
Finally, a brief introduction to the mainstream of home lighting: energy saving lamps, halogen lamps, LED lamps.
Energy-saving lamp life of up to 10,000 hours, the price is lower than LED lights, but the energy-saving lamps contain mercury vapor may cause mercury pollution, heavy use is not recommended in the home lighting.
Halogen is an incandescent lamp, and life in general between 3000-4000 hours, due to the relatively short life, light a lesser extent, this lamp is generally used in indoor and accent lighting.

The profound influence of LED to lighting disciplines
Material basis of lighting is light, the human daily life nearly half the time in the sun, which is a natural source. But led street lights price humans need artificial light for illumination. After a long phase of artificial light from the burning wood, oil, gas and produce light, the 1879 Edison invented the incandescent electric light artificial light from entering the era, to achieve a qualitative leap. Existing electric light including incandescent, halogen, represented by thermal radiation source, and gas and fluorescent lamps, high pressure mercury lamp, high pressure sodium, metal halide light sources as the representative of the discharge. In LED solid-state lighting is represented in recent years, the rapid development of lighting technology disciplines.
Photometric lighting disciplines to develop and improve basic around 1760, scientists Lambert (Lambert) has made major contributions to this. This time, due to human has not yet entered the era of electric light, which photometry is leaving the imprint of that era, such as candle (candela). Colorimetry was initially established in the 1930s, after 70 years of perfect. Practice has proved that, photometry, colorimetry suitable for natural light, artificial light, thermal radiation, including lighting, gas discharge light source and other traditional sources of electricity.
In recent years, with advances in solid-state lighting technologies such as LED, LED has received a lot of humanity in the field of visual applications, including display and general lighting, but also a lot of non-application of human vision. If we illuminate subjects defined as "direct application of research source science and technology," the subject, then the visual and non-visual application source applications will be subject areas of study lighting, light vision applications can be called a vision lighting discipline (illumination science), or narrow lighting disciplines, while the lighting disciplines include visual and non-visual applications application called generalized (lighting science).
As a new light source, LED light source is different from the traditional principle. And thermal radiation source depend on the material high-temperature heat radiation, gas plasma gas discharge light source emitting different rely, LED by electrical injection, the electrons and holes injected from the opposite direction to a specific light-emitting area, i.e., the light-emitting layer, and the light-emitting layer composite light. This new LED light principle decision has the following characteristics:
1.1 Small
The LED may be very small, the current 0.5mm * 0.5mm is very easy to do. Due to small size, in three-dimensional space concept LED is expected to meet any demands. You can almost say, in three-dimensional space, LED is a basic element of this element can be used to piece together any shape luminous body. For example, if you need to use 6 LED to piece together a complete luminous body, then we can achieve a variety of possible shapes shown in Figure 1, this is only the plane, as well as three-dimensional three-dimensional case.
1LED can do little
LED small volume of a further advantage is that due to the small size LED, luminous dots smaller. It's almost understandable in optical design for a point source, while the second optical design point source is convenient, therefore, will determine the LED light distribution to fit almost any requirement. Figure 2 is a free-form surface plus LED optical lens to achieve special spot pattern.
2LED add free-form surface to achieve special optical lens flare pattern
1.2 narrow spectrum
In principle from the LED light, LED essentially monochromatic emission spectrum, but because of spectral broadening of a certain width, typically 20 nm ~ 30nm. And now has a band of various monochromatic LED, as shown in FIG.
3 narrow spectrum
Since the LED of monochromatic, therefore, in this space spectrum, using a plurality of LED can be composed of almost any desired spectral shape, and this combination is no loss of efficiency. In other words, LED in this one-dimensional spectrum, LED has the concept as an essential element to achieve the various needs of unlimited possibilities. Traffic lights, backlight RGB system is a typical application.
1.3LED switch short time
LED ns switching time is orders of magnitude. Therefore, this is equivalent to this space at the time, LED has the basic elements and the illumination of the function, that is, on the time scale, LED is arbitrary. This bio below includes humans, plants of light intervention, there will be a lot of applications.
The above analysis of the LED is small, pure spectrum, switching time is short features, which are different from the traditional LED light source, the most important feature, it is these advantages, creating a LED unlimited application possibilities and the possibility of future as a mainstream source. If these three LED unlimited flexibility painting into a three-dimensional space, as shown in Figure 4, then the reality of the vast majority of lighting applications should be able to find the appropriate place in this space.
4LED short switching time
However, unlimited application possibilities of this LED to be a reality for mainstream applications require multiple conditions, including higher compared with the existing light source efficiency, lower prices. Currently on the market has been very easy to buy light efficiency 120lm / W of LED, higher than most of the traditional light sources, LED lamps and some prices have been close to the level of traditional light fixtures. Meanwhile, with the advances in technology LED light efficiency still further improved, prices are rapidly declining. Therefore, LED light source into the mainstream already foreseen. Because LED high degree of flexibility, therefore, LED will have a profound impact on the light source illuminating the material basis for discipline.
LED lighting to expand the connotation of discipline
It should be said, the limitations of traditional light sources, lighting the traditional discipline is to study the visual lighting, because the main purpose of the light source is to help people clear seeing the world, although there are a small number of other uses, but compared to the vision applications, it is much smaller . Therefore, in practice, in fact it is the traditional lighting discipline discipline vision lighting, in which the colorimetric main theories are published by the International Commission on Illumination (CIE) and finalized, therefore, CIE is an authority in this area of the world monopoly in the field say.
However, as mentioned earlier, LED determine the characteristics of it in addition to doing visual purposes, there are many applications are not visual purposes, namely non-visual applications. Now known mainly include agriculture,, medical. If the light used in these areas are known as generalized lighting disciplines, then the connotation that the lighting disciplines will greatly get extended.
2.1LED application in agriculture
LED applications in agriculture, including LED fill light for plants. Because sunlight rely on photosynthesis for plant growth, biological statistics show that the majority of green plants, which contain chlorophyll a and chlorophyll b. Chlorophyll a and chlorophyll b is selective absorption spectrum, as shown.
5LED application in agriculture
Figure 5 shows that contain chlorophyll a and chlorophyll b plants, which absorb green light is very small, green is most reflective, thus appears to be green. The main absorption peaks are 650nm and 440nm two peaks nearby, and chlorophyll a and chlorophyll b wash absorption peaks different but relatively close. Therefore, we can consider the growth of plants is absorbed mainly by these spectra for photosynthesis. Further studies showed that the absorption and photosynthesis of plants to different wavelengths of light are not the same. This from different plants have different colors (i.e., the reflected sunlight portion) can also be understood.
As the LED spectrum has great flexibility, so we can choose the right plants for different spectral irradiation plant, it is conceivable that such plants fill light than conventional light sources would have great efficiency advantages. In this LED applications, establishing different spectral efficiency curve plant photosynthesis is the basis of efficiency, this with the human eye see the function curve is a concept, but for different purposes only. Therefore, with the current Visual Sciences correspondence, whether the plant will produce photosynthesis science?
led street light wholesale in agriculture also includes many aspects, such as pesticides, antibacterial. Such as certain insects to certain spectrum, fungi inhibited, then this inhibition study as great significance. Another type of lighting will be born this research.
LED in the animal breeding is also great utility. Currently LED used to study animal breeding, including chicken, fish and so on. In these applications, light is used to give an animal to create a bright environment, this is similar to human light environment. However, different light environment whether different animals have different growth-promoting effect? If so, then the LED light unlimited flexibility in the manufacturing environment, and thus there may be a different species preferred illumination light environment. This will also be illuminated scientific study.
2.2LED application in medical care
LED applications in medical care, including light therapy and rehabilitation, health care and so on.
Phototherapy (light therapy) principle is: the ability of a specific wavelength of monochromatic light on the biological behavior of cells, while no significant injury. As has long been irradiated with laser light, however, due to its bulky, expensive, and only a small point of light emitted can not be irradiated with a large area of the wound, while in addition to expensive for the limited wavelength tunable laser laser has a value generally, and therefore can not achieve the irradiation light wavelength is preferably, and the laser is an energy inefficient light source, such that these problems in the medical laser applications is limited.
Compared with the laser, LED light source is small, relatively cheap, and has a variety of spectrum, which can be arranged with multiple LED arrays used in large-area wounds irradiation characteristics, through the choice of a different wavelength LED light therapy can be achieved preferably the wavelength, plus LED light efficiency, so that the LED on the light therapy has great potential. LED applications in medical care and rehabilitation is also based on the same reasoning.
In the above medical applications of these LED, there is a LED illumination same preferred problem, that is, for a particular treatment, what type most suitable spectrum? What kind of strength, such as how the exposure mode steady pulse mode or the most appropriate way? How best irradiation cycle? These are all worthy of scientific research are broad subject areas lighting.
LED applications in medical and agriculture on a little different. Application in agriculture, light may be selectively for one or more objects. As far as the effect of a positive, or a positive effect plus one or a few negative effects, such as inhibition of the growth of certain plants. However, in medical applications, due to the human body with a variety of organizations, then LED lighting not only to consider promoting growth of certain tissues, but also consider the damaging effects of a variety of other organizations. Therefore, LED-disciplinary research in medicine and more complex. If this is included in the lighting disciplines, then this part of the lighting disciplines will be a long research process, will produce a series of illuminating subjects branch.
With the development of LED technology, in addition to the above, LED will be in many areas of the birth of a variety of applications. Studies of these applications will also greatly enrich the connotation of lighting research disciplines.
It is worth mentioning that, LED and communications technology combine to produce an LED visible light communication technology, and there is a great prospect. With the development of electronic technology, wireless communication technology has become the main communication. However, wireless communication is the need to allocate channels, and thus the channel will become increasingly nervous. The use of LED fast switching characteristics, when the switching frequency is higher than the human eye blink frequency identification, can be realized by fast switching LED transmission signal, a visible light communication technology is the LED. With the development of LED technology, as the mainstream light source for general lighting around the corner, so the load on the LED lighting LED communication would be a cheap and reliable means of communication at the same time secure. However, the need of special note, in the communication LED, LED is just a carrier. Thus, although the future of which is associated with the lighting of a cross-disciplinary, however, strictly speaking, this does not belong to a part of the lighting disciplines, but rather part of the communication disciplines.
LED lighting subject to change focus
Lighting disciplines is photometry, colorimetry for discipline based. Which photometric Lambert (Lambert) was founded in 1760 by scientists, and colorimetry experienced relatively lengthy process of improvement, from CIE1931, CIE1964, CIE1976 repeatedly CIE chromaticity correction system, while the color of the evaluation index had experienced the same long process until 1974 was basically finalized. However, after nearly four decades since, lighting discipline itself is not much progress. This is mainly because, as the material basis of illumination, including thermal radiation source, a gas-discharge light source, because of its light-emitting principle basically established, and there are no major changes in the basic form of the spectrum, and thus to photometry, colorimetry based lighting disciplines can basically meet the needs of the practice of using these sources of illumination. However, this time, the light source technology is always in progress, despite this progress is slow. The main highlight of the light source is to improve the efficiency, life, color and so on. Specific research is to find a new light-emitting substance or a new excitation light source. Compact fluorescent lamps are very important inventions during this time, which in the 1980s, during the past decade, research studies since then makes it light efficiency, especially in the life of color to get a lot of progress, so that by far the CFL the main sources of indoor lighting. Began in the 1960s HID light source, until the early 2000s has been a hot research sources, and get a lot of progress in the lamp light effect, color, and other aspects of life. Research in this area is also the birth of another important international conferences and organizations in the field of lighting, namely LS: XX Conference and FAST-LS, and LS meeting as the most important international conferences in the field of lighting in addition to CIE.
Therefore, nearly 40 years, has been the focus of the lighting disciplines as the material basis of illumination light source, rather than the lighting itself. However, LED's appearance will change this situation.
In recent years, the United States, Japan, Europe, South Korea and China, including China, Taiwan and other regions, have invested in the government's support for LED research, and LED technology to get a lot of progress, including LED light effect, from ten years ago 10lm / W or so to the current commercial products 130lm / W, while the laboratory sample has reached 300lm / W or more, and the price dropped to an acceptable degree of market fundamentals. At the same time due to the longevity of LED devices, and so has been greatly improved reliability, thus LED in scale space, unlimited flexibility in spectrum space and time and space are increasingly shown its advantages. Currently LED signal display and other areas also include a backlight display applications, has become a mainstream source. In the visual field of lighting, including lighting indoor, outdoor, etc., LED has gained more and more market share, and these could have been the main application areas of traditional light sources. And the field of agriculture, health, communications and other front analysis in recent years, the rapid growth. These are due to the infinite flexibility of the three LED scale space, time and space, due to spectral space. However, because these three unlimited flexibility, LED in all of these applications, in most cases there will be an optimal solution of the problem. And this problem is to conduct research on academic need. Thus, with LED visual and non-visual field applications continue to expand the depth and breadth, has also given a lot of development opportunities lighting disciplines, these are lighting the discipline itself, rather than the material basis of lighting - light.
When the above discussion LED limitless future prospects, are based on three LED unlimited flexibility. However, the current development of LED and LED not fully achieve this flexibility, especially LED spectrum unlimited flexibility. LED current spectral half width of 20 ~ 30nm, and the LED by varying the doping material can achieve most of the visible spectral range. Each center is currently achievable wavelength photoelectric efficiency LED is different, in particular a very low efficiency of the green LED.
6LED unlimited future prospects
Figure 6 is the year 2007 Krames and other external quantum efficiency of map drawing, although in recent years, LED efficiency has been greatly improved, but the efficiency of the green part of the LED remains low, the current commercial products are still below 20%. Therefore, the present LED device to realize a monochromatic LED spectrum unlimited flexibility, i.e., by assembling a plurality of single-color LED to achieve a variety of spectra, and if it contains a green LED, the assembly will lower the spectral efficiency, in order to As for the practical significance will be greatly reduced. Thus, a green LED to improve photoelectric efficiency will be achieved by LED true spectrum unlimited flexibility necessary condition. Before the green LED efficiency has not yet been greatly improved, research to improve the photovoltaic efficiency green LED accent lighting will be a research subject.
Photometric lighting disciplines to develop and improve basic around 1760, scientists Lambert (Lambert) has made major contributions to this. This time, due to human has not yet entered the era of electric light, which photometry is leaving the imprint of that era, such as candle (candela).

Which photometric Lambert (Lambert) was founded in 1760 by scientists, and colorimetry experienced relatively lengthy process of improvement, from CIE1931, CIE1964, CIE1976 repeatedly CIE chromaticity correction system, while the color of the evaluation index had experienced the same long process until 1974 was basically finalized. However, after nearly four decades since, lighting discipline itself is not much progress. This is mainly because, as the material basis of illumination, including thermal radiation source, a gas-discharge light source, because of its light-emitting principle basically established, and there are no major changes in the basic form of the spectrum, and thus to photometry, colorimetry based lighting disciplines can basically meet the needs of the practice of using these sources of illumination. However, this time, the light source technology is always in progress, despite this progress is slow. The main highlight of the light source is to improve the efficiency, life, color and so on. Specific research is to find a new light-emitting substance or a new excitation light source. Compact fluorescent lamps are very important inventions during this time, which in the 1980s, during the past decade, research studies since then makes it light efficiency, especially in the life of color to get a lot of progress, so that by far the CFL the main sources of indoor lighting. Began in the 1960s HID light source, until the early 2000s has been a hot research sources, and get a lot of progress in the lamp light effect, color, and other aspects of life. Research in this area is also the birth of another important international conferences and organizations in the field of lighting, namely LS: XX Conference and FAST-LS, and LS meeting as the most important international conferences in the field of lighting in addition to CIE.
Therefore, nearly 40 years, has been the focus of the lighting disciplines as the material basis of illumination light source, rather than the lighting itself. However, LED's appearance will change this situation.
In recent years, the United States, Japan, Europe, South Korea and China, including China, Taiwan and other regions, have invested in the government's support for LED research, and LED technology to get a lot of progress, including LED light effect, from ten years ago 10lm / W or so to the current commercial products 130lm / W, while the laboratory sample has reached 300lm / W or more, and the price dropped to an acceptable degree of market fundamentals. At the same time due to the longevity of LED devices, and so has been greatly improved reliability, thus LED in scale space, unlimited flexibility in spectrum space and time and space are increasingly shown its advantages. Currently LED signal display and other areas also include a backlight display applications, has become a mainstream source. In the visual field of lighting, including lighting indoor, outdoor, etc., LED has gained more and more market share, and these could have been the main application areas of traditional light sources. And the field of agriculture, health, communications and other front analysis in recent years, the rapid growth. These are due to the infinite flexibility of the three LED scale space, time and space, due to spectral space. However, because these three unlimited flexibility, LED in all of these applications, in most cases there will be an optimal solution of the problem. And this problem is to conduct research on academic need. Thus, with LED visual and non-visual field applications continue to expand the depth and breadth, has also given a lot of development opportunities lighting disciplines, these are lighting the discipline itself, rather than the material basis of lighting - light.
When the above discussion LED limitless future prospects, are based on three LED unlimited flexibility. However, the current development of LED and LED not fully achieve this flexibility, especially LED spectrum unlimited flexibility. LED current spectral half width of 20 ~ 30nm, and the LED by varying the doping material can achieve most of the visible spectral range. Each center is currently achievable wavelength photoelectric efficiency LED is different, in particular a very low efficiency of the green LED.
6LED unlimited future prospects
Figure 6 is the year 2007 Krames and other external quantum efficiency of map drawing, although in recent years, LED efficiency has been greatly improved, but the efficiency of the green part of the LED remains low, the current commercial products are still below 20%. Therefore, the present LED device to realize a monochromatic LED spectrum unlimited flexibility, i.e., by assembling a plurality of single-color LED to achieve a variety of spectra, and if it contains a green LED, the assembly will lower the spectral efficiency, in order to As for the practical significance will be greatly reduced. Thus, a green LED to improve photoelectric efficiency will be achieved by LED true spectrum unlimited flexibility necessary condition. Before the green LED efficiency has not yet been greatly improved, research to improve the photovoltaic efficiency green LED accent lighting will be a research subject.
which of LED lighting businesses will be out in 2015?
2014 is a year of surging rapids behind "Integration", "broke the first year", "channel in" and other words reveal faint industry impatience and bustle. In this led to a large LED inside, filled with laughter and tears, filled with loss and longing. Awarded the Nobel blue LED, the led high bay lighting wholesale people proud; NVC storm twists and turns, the industry affects people's nerves; Lynx electricity supplier rise next digit myth lamp enterprises have invested in the arms; small cross-border robbery, so everyone exclaimed injury can not afford; intelligent digital era, lighting electrician to integration; integration of acquisitions shock the industry chain, stepping down gracefully but rather wise ......
Industrial environment is not good, resulting in many businesses struggling, what kind of lighting brands will be eliminated? International lighting brand giants elites give different answers.
Among them, the "big coffee technology" business general manager and technical director of China Shao Jiaping Cree believed to have talent, technology, brand, channel, there is innovation; Zhou Xuejun, director of the Asian Pacific market, "Big Mac" Philips is frankly, the industry downturn, Philips can not stay out of big companies may become small, small businesses are likely to collapse out; Osram (China) sales Director Chen Qi believes that under closures businesses to stay in the market analysis, operations management and other aspects of one side to the market; (GE) lighting, general manager of the international giants General Electric brilliant light is thrown four Cheats - cost, quality, channel branding, product innovation; Cooper, general manager of Asia Pacific Electric Heman believes tap into the potential market areas, with the importance of patents to enter the international market; Tang Guoqing, general manager of Samsung LED China believes that learning and innovation is the key to survival and development ......
In short, to survive and live a good business has a lot of reasons, but let one out of business failures is enough. So what kinds of LED lighting companies will be eliminated in 2015 quit?
The first is the lack of corporate cash flow. Business has always been a money-strand breaks most direct "cause of death." Currently LED hustle dazzled many bosses like to play with blood, loss of the original sense of the Office of Industrial practical, busy expanding production capacity, stepping up the layout, but sluggish business environment, competitors surge in input and output ratio imbalance, the profit decline, allowing companies exhausted their own pockets, and then maneuvers suppliers and auto loans, and finally emptied vigorously promote their own inventory, when there's nothing left, promising immediate bankruptcy, is a nasty run the.
Secondly, there is no core technology businesses. If the LED is a war, then the technology is equivalent equipment, hand knives when companies face roaring bullets outcome of the battle is not self-evident. Look from the LED industry chain, covering several aspects of its substrates, epitaxy and chip, package, application, involving many fields of microelectronics, optical, thermal, etc; from the production point of view, a number of people a hundred assembly plant, even beat several semi-automatic production equipment.
The third channel is excessive superstition electricity supplier companies. This year's "double eleven", Op lighting to 94.3 million yuan to create the myth of electricity providers, many lighting companies have "shock" and even some business interests regardless of the channel under the line, practicing "magic electricity supplier." In fact, the electricity supplier, increasing competition, rising operating costs online, an increase of 8% from the initial 20% to 35% -42%, an electricity supplier into the deep sea, when the company "brandished a knife from the Palace" moment , actually lose the foundation upon which to build the channel, thus embark on a road of no return.
The fourth is an avid open up channels of the enterprise. led high bay light for sale has entered the arena to fight really intense, vigorous marched led high bay light for salemarket line, all kinds of advertising bombardment, slogans inspire passion, tasty attractive channel policy, "beating, smashing, looting" channel on the sports are played every day. However, the limited space in the market, financing capability, channel management, business cooperation mode and other factors, making it possible to hang on until the last business is not much, you know, "keep country DaJiangShan harder than."
2015 has really come, sooner or later be eliminated for businesses that can not necessarily jiliuyongtui a good thing, after all, the industry does not need so many LED lighting business.

On development trend of led intelligent lighting
Industry sources are considered, lack of consumer awareness of the intelligent lighting market in its infancy is the main reason. In recent years, with the rapid development of the national economy, especially the rapid development of the real estate industry's triumph, the intelligent lighting industry, the emergence of a variety of technology types of manufacturers, the market also appeared in various types, distinctive smart switch products.
Although the field of led street lighting Manufacturer control no scale national consumer market, but most manufacturers are still highly intelligent lighting to guide consumers on the construction of channels has also been exploring the model for the industry, realistic demand for products in increasing strides functional positioning and stability have been achieved. Manufacturers, distributors, integrators and decoration companies, regional sales continue to accumulate experience.
The unique charm of intelligent lighting
1. Automatic dimming Intelligent lighting control system can be fully automated state job. There are a number of basic state system, the state will automatically switch between them at a pre-set time, automatically adjust the illumination to the most appropriate level.
2. The full use of natural light Adjustable features of controlled light construction equipment (such as blinds) to adjust the control of natural light, and lighting systems can not even move. When the weather changes, the system can automatically adjust, no matter what place or how the weather changes, the system can ensure that the indoor illumination maintained at pre-set level.
3. Consistency general illumination lighting designer for the new buildings for lighting design, will be taken into account over time, and the room lighting efficiency attenuation wall reflectivity, and therefore its initial illumination are set too high. This design not only resulted in the building with the use of the illumination period (or twice decorated interval) is inconsistent, but also because of the high illuminance at the beginning and an unnecessary waste of energy. With intelligent lighting control, though still high illumination design, but can be intelligent dimming, the system will follow the standard pre-set brightness to maintain a constant illumination lighting area, regardless of lighting efficiency and reduce the reflectivity of the wall attenuation affected.
4. Light Conversion Intelligent Scene Intelligent lighting control system can be pre-set different scenarios modules, necessary as long as the corresponding control panel can be transferred to the desired scene. Users can also programmable control panel on the scene in real-time adjustment to suit different requirements. In addition, users can also change settings in different scenarios through an interface with a portable programmer.
5. The operation of energy-efficient intelligent lighting control systems for most lamps (including incandescent, fluorescent, with special ballast of sodium, mercury, neon lights, etc.) for intelligent light, to where it is needed, the time needed to adequate lighting. To turn off unneeded lights, full use of natural light, which runs the full energy savings. Intelligent lighting control can generally save 20-40% of energy, not only reduces electricity costs for users, but also reduce the supply pressure.
6. known to prolong the life of the light source, light damage is mainly due to over-voltage grid, as long as appropriate to reduce the operating voltage can extend the life of the light source. Intelligent lighting control system uses the soft-start approach to control the impact on the grid and surge voltage to the filament from thermal shock, so that the light source is 2-4 times longer life for the extensive use of light and difficult to install a more specific area significance. In short, the combination of intelligent and lighting technology, and build a full technology platform, energy saving, low power consumption, long life, save, people-oriented, such as green and sustainable lighting concept full interpretation.
Intelligent lighting application prospects
1. The home field - offers a comfortable living space traditional control opening and closing of the way, limiting the modern fast-paced lifestyle. With the development of science and technology and people's living standards improve, people on home office lighting system put forward new requirements, in addition to controlling the light illumination time, brightness, but also with the home subsystem fit for different applications and create appropriate lighting scenes, but also to consider the management of intelligent and simple operation, and flexibility to adapt to future changes, such as lighting layout and control requirements. A good intelligent lighting system can enhance the quality of the home environment, and ensure a comfortable and healthy family life. So, instead of the traditional switch network switches, intelligent lighting system to replace the traditional lighting systems, home automation is an inevitable step in the process.
In the home life, intelligent lighting and storage devices through different preset lighting scenes, to adjust the room lighting changes, to meet the different needs of the owner of the room. For example, in guest visits, at the party, you may need brighter lights, and enjoy classical music or when soft music, soft lighting is used; and when should the living room into a home theater to watch a wonderful movie, more lights were dim need adjustment, all this can sit comfortably on the sofa operation, save one by one the lights turn off the lights in the past trouble trouble trouble. A key in hand, creating fantastic light blossoms.
Intelligent lighting control, indoor lights can be operated in a manner that all pre-set these default status by setting the program cycle to work. Analogy, when we open the preset light (or in accordance with the home time setting) at 7 o'clock, at 7:00 later when you get home, lighting system will automatically enter you set a good working condition, and will be based on different slowly adjust the way the house lights.
We can also be programmed to randomly change the light intensity of each region, in order to meet the needs of a variety of topics and the house owner mood. Importantly, intelligent lighting system can also make good use of natural light, depending on the weather changes, adjust the illumination to the most appropriate level.
Intelligent lighting system so that people living in the most comfortable state, regardless of the indoor area. With the promotion of intelligent lighting systems in the market, has increasingly shown its advantages in such a system brings a variety of functions at the same time, the owner returned to a more comfortable living space.
2. The office area - to improve efficiency in the energy content in detail, please pay attention to the "Digital Communities & Smart Home" 8 issue of the "smart home lighting control product topics." Number Chi network will also launch a special report, please pay attention.
Atmospheric and beautiful office environment, bright and comfortable light; entered the conference room, the lights automatically turn on smart, automatic control illumination and quantity of light through the pre-programmed lighting system, the interior lights adjust to the most appropriate to meet the state; meeting ended leaving the room, the lights turn off automatically; when the window is changing natural light, indoor lights also will be automatically adjusted, voluntarily conserve energy ...... so advanced office lighting environment, and now has begun to show in the large office building .
Office space represents a company's image. The staff intelligent and convenient working environment make the office more comfortable. In today's fast-paced, busy office workers busy daily affairs, simple, flexible, comfortable office environment that allows them to feel good, to effectively improve work efficiency. Intelligent office lighting for office brings convenient, user-friendly design, for example, in the conference room using the intelligent automatic dimming system has a variety of pre-set scenes, a simple one button you can switch out different lighting modes, for office staff needed to provide the best comfort lighting, so that employees in the best working condition.
At the same time, a good awareness of energy conservation can be perfectly reflected in the intelligent office lighting. Automatic sensor control device intelligent system can effectively utilize natural light, so the lighting environment to maintain constant illumination, but also can automatically shut down no regional staff of the lighting equipment, to minimize unnecessary energy consumption, the maximum can reach 75% energy saving effect.
In short, advanced lighting and comfortable like beautiful music, in the subtle influence among the people working condition. With the daily business affairs increasingly busy people to stay in office longer and longer, focus on the work environment has become even more emphasis on high-quality office stationed intelligent office lighting will enhance people's working efficiency.
3. Public facilities in the field - green intelligent lighting applications, safety and environmental protection in public facilities is very important. With the development of technology, can in some bridge tunnel, instead of the traditional use of smart street lights, this "smart" street lights can not only weather, but also with the intensity of the sun's rays and automatically adjust the bridge lights strength, both humane and energy.
Currently, many of the most common problems dong bridge is too dark, vulnerable to accidents. With intelligent lighting under the bridge began in the trial, this situation has been changing slowly. Such as the application of the current international popularized the led street light wholesale stepless control system that allows the luminous intensity tunnel light as the sun rises in the morning and gradually increased, in the afternoon as the sun will gradually weaken and west, until the close daytime lighting.
The development direction of intelligent lighting
1. Brand integration will be the development trend of intelligent lighting brand integration will be the development trend of intelligent lighting. The different brands of products to the greatest benefit of a centralized platform, is the brand's best products will focus on a project in the past, and thus improve the intelligent home. In fact, a wide range of lighting products on the market, if the requirements are the same for all the equipment manufacturer's products, or a system can only use the same manufacturer for all product support, is unrealistic. Moreover, customers in terms of performance and price and lack of autonomy - either accept, or only give up all. Unified control platform is able to be well balanced, the customer can choose any product, as long as it also meets the requirements in terms of performance, so that customers in the budget will be a great initiative.
2. to the people-oriented scientific lighting, intelligent lighting from a purely intelligence shift more attention to the development of intelligent lighting human behavior. In human behavior, visual effects, visual physiological basis of psychological research, develop more scientific content, people-oriented and efficient, comfortable, healthy, intelligent lighting.
3. To meet the individual combined level of lighting technology and intelligent lighting illumination further meet the different individual needs of different levels of lighting groups, is to meet ordinary people from lighting to meet the needs of the individual, the individual needs of essential technical means. This should also be the development direction of smart lighting.
4. Intelligent Technology and new sources and new lighting technology, to create a new lighting culture combines smart technology and electronic ballasts, and other new lighting and lighting technology, will build a new lighting technology platform, and its applications from the smart home intelligent lighting to illuminate the city, there are infinitely broad prospects, and are creating a new culture of high-tech lighting and high levels of scientific thought. Emergence of intelligent lighting fixtures market ushered heat conferences gave more expectations

Six degrees of intelligent lighting standardization development at home and abroad
Edison invented the incandescent lamp has 100 years, although there are many countries because of its ban on the use of energy efficiency is too low, but it changed human invention "sunrise till sundown" way of life, so it is a great revolution ; new lighting after the development of electronic technology, but also through the device of buy led high bay lamps chopper junior intelligence technology and the continuous development, endless wisdom lighting, intelligent lighting, lighting systems, visible location and communication conceptual way.
LI Zi-li, according to reports, intelligent lighting standardization can be divided into six stages:
The first phase, as early as 1990 the American Society theater release DMX-512, which is a fast, simple and practical protocol for intelligent lighting, but due to the seven digital, which is of limited function, and does not require lighting instruction of each function, and therefore does not have a true sense of interchangeability.
The second phase, in 1996 the fluorescent electronic ballast control technology write IEC60929 standard, with intelligent lighting in the true sense, but only for fluorescent lamps, 2009 International Electrotechnical Commission issued a number of sources, including controls and control functions IEC62386 series of standards within a relatively sound intelligent lighting. After the International Electrotechnical Commission TC34 organization of national experts to revise and develop, 2014 has introduced several FDIS document, there is a big difference with the first edition. Cloth two control lines needed in the future will soon be conducted convenient wireless control.
The third phase, power line carrier control susceptible to interference, slow, low function; no recognized uniform lighting special function instruction set compatibility can not be both.
The fourth stage, other cree xsp series led street light can integrate other building smart home system, but no accepted unified instruction set, lighting, special features, compatibility can not be taken into account.
The fifth stage, radio control: Wi-fi, zigbee, toothblue and other convenient and practical, but no accepted unified instruction set, lighting, special features, compatibility can not be taken into account.
The sixth stage, the domestic league standard: State Lighting R & D and Industry Alliance, Alliance Semiconductor Technology Assessment and so active in organizations and promote intelligent lighting research and standardization.

The second phase, in 1996 the fluorescent electronic ballast control technology write IEC60929 standard, with intelligent lighting in the true sense, but only for fluorescent lamps, 2009 International Electrotechnical Commission issued a number of sources, including controls and control functions IEC62386 series of standards within a relatively sound intelligent lighting. After the International Electrotechnical Commission TC34 organization of national experts to revise and develop, 2014 has introduced several FDIS document, there is a big difference with the first edition. Cloth two control lines needed in the future will soon be conducted convenient wireless control.
The third phase, power line carrier control susceptible to interference, slow, low function; no recognized uniform lighting special function instruction set compatibility can not be both.
The fourth stage, other cree xsp series led street light can integrate other building smart home system, but no accepted unified instruction set, lighting, special features, compatibility can not be taken into account.
The fifth stage, radio control: Wi-fi, zigbee, toothblue and other convenient and practical, but no accepted unified instruction set, lighting, special features, compatibility can not be taken into account.
The sixth stage, the domestic league standard: State Lighting R & D and Industry Alliance, Alliance Semiconductor Technology Assessment and so active in organizations and promote intelligent lighting research and standardization.
