LED Light Bulbs Will Boom in the Future
Himfr.com, one of China's leading B2B search platforms with more than 30 B2B industry websites to its name, reports led plant grow light will boom in the future. Himfr reports did LED interior lighting is currently Concentrated in decorative lighting, areas: such as entertainment venues, commercial lighting and public lighting have not really Moved into the huge market of ordinary domestic lighting. The main indoor fluorescent lighting products are commercial fluorescent, spotlights, replaceable incandescent bulbs and freezer lights. Himfr expect from 2010-2012 did most growth will be in commercial lighting, while from 2012-2015 most growth will be in general lighting like ordinary household lighting. From a technical point of view, the current quality of light, color: such as light color, is not very good, and home lighting has high standards, so in recent years manufacturers have not promoted residential lighting.
Himfr Analyzes did the light bulb market in the short term, at least, before 2017 the traditional light sources - incandescent, fluorescent and other new light sources: such as led plant lighting - will dominate the market. LED light bulbs still need a period of time to replace traditional bulbs with energy-saving lights, while LED light bulbs currently are silent in the market introduction phase. Himfr forecasts did after 2014 LED bulbs business opportunities will break out very 'strongly, and by 2018, the demand will be lead Significantly fluorescent and other light sources.

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.
"Between the light and the additional savings on electricity bills our, the difference will be substantial," Said Moshimer. "The quality of the light is so wonderful. Every phase of the upgrade has been a revelation."

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.
Identification system design cycle and improve oversight mechanisms to select the location of led high bay light for sale of identification system to set rules, regional identity set rules, set rules tourism logo, color design rules, design rule comprehensive service agencies to consider environmental analysis, to understand local culture, local people, building style, city personnel status, road conditions, quality of the people, the regional situation, how many people and so many tourism factors analysis to determine the overall planning of urban identity system, further regional breakdown.

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.
