Japan led street light fixtures manufacturers

Commercial led street lighting fixture emphasized on energy saving and stability

Country has always been practicing the concept of energy saving and spirit all the time in the transport sector also respond to the call of the country. To this end, power-saving features Country has always been practicing the concept of energy saving and spirit all the time in the transport sector also respond to the call of the country. To this end, power-saving features LED traffic engineering side of the display is an important indicator of purchasing products . LED traffic display, especially on the highway installation guidance screen, usually thick cables need to be connected to provide current, while stretching several kilometers to tens of kilometers or even longer cable cost is undoubtedly a huge cost inputs. On the other hand, commercial led street lighting fixture requires 24 hours of uninterrupted work, but also need to focus on consuming power considerations. Thus, LED traffic display whether saving is an important factor in relation to the project cost.
In order to achieve energy savings, LED display manufacturers in the design and manufacture of products in a big fuss. Only rational design, fully consider the lighting conditions, day and night, according to a completely different light from outside my body to adjust screen brightness to match the normal vision of the human eye, in order to ensure long-term reliable LED Traffic Signs, energy-efficient use. Han Yuan Heng from both hardware and software aspects, screen body temperature is reduced as much as possible to ensure minimum loss of product realization.
In addition, commercial led street lighting fixture is also reflected in the visual targeted. LED traffic display effect is to show traffic information, traffic information provided to and from vehicles and pedestrians, and thus play a guide, reminder or warning role. This particular application areas determines the LED traffic display simply displays the text or symbols, and is only available to drivers on the road, travelers watch. Height is too high or too low of transport do not need to see the top of the screen content, therefore, need not be too pursuit of conventional traffic-screen display and a variety of colorful high-end performance, but should emphasize energy-saving features. Han Yuan Heng than ordinary LED traffic display screen more than 75% energy saving, energy-saving effect is obvious .
Stability is the LED display to emphasize the basic performance, LED traffic display in particular, need to work hard on stability. As the product is installed in almost all outdoor locations, differences in climate around the world is great, the weather changes throughout the year to form a complex and changing environment test, if the performance is unstable, one of the great inconvenience caused by maintenance, two is the loss of the traffic operator and display manufacturers economic interests, or even to allow the manufacturer’s reputation was severely hit.
LED traffic display to ensure the stability necessary to allow each one lamp beads have played a full energy efficiency, so that the energy input into the full light effectively, thus ensuring consistent brightness of the entire screen. Commercial led street lighting fixture project involves more than one object transport sector, the construction sector, engineering side, side and display system manufacturing, etc., and sometimes from the construction project bidding and then acceptance of the need to go through a few years, and LED traffic display the installation went up early . In this case, if the display is not enough stability of the product, resulting in acceptance is not successful, then the recovery of money becomes extremely difficult, and this for the LED display manufacturer is a fatal blow. Han Yuan Heng began to start from abroad to foreign traffic display stringent requirements apply to domestic, five-year product warranty. engineering side of the display is an important indicator of purchasing products .

China's overall development and application of commercial led high bay lighting wholesale industry is relatively stable On the one hand, expanding market applications, technical progress obviously, technological innovation and new product stimulating corporate profit growth;. Hand market competition continued to intensify, individual enterprises setbacks.
overall sales market scale of commercial led high bay lighting wholesale industry maintained steady growth, with advances in optoelectronic materials, the rapid development of LED display technology, to further expand market applications, LED display enterprises not only to broaden the field of display, and the depth of the development of LED lighting products, but to explore the outdoor media market, these are the LED display enterprises and the development of self-beneficial attempt to break through.
In 2013 there have been many innovations and new products, such as high-density fine pitch LED display products gradually in the interior areas of commercial large-screen occupying a seat position, is expected to gradually replace the traditional DLP, LCD and other display devices . Along with the outdoor surface mount packaging technology to improve and enhance the level of protection of modular outdoor, extreme outdoor full color pixel center distance is constantly being refreshed, outdoor surface mount alternative to the big screen to become in-line screen.
As a fully market-oriented LED display applications industry, opportunities and risks. China's LED display is still sharp price competition in the market. Whether it is an emerging market or traditional display market, the price is always the primary means of competition. The new lease, cooperation mode LED display market funds and risk products manufacturing enterprises challenges, some small businesses are not hurt. Individual companies (including more well-known companies) have fallen, the so-called theory of shuffle, winter on temporary rampant.
In fact, LED display industry development bottleneck encountered several enterprises not represent the entire industry, for the industry as a whole, there are several hundreds of companies issue corporate inevitable. Competition within the normal range, in the course of its development, will be another round of reshuffle in any one industry, a wave of corporate knockout complete the self-evolution. Survival of the fittest is the law of nature, commercial led high bay lighting wholesale industry market screening is a normal phenomenon, I think the industry do not have to panic too much.
Note that, commercial led high bay lighting wholesale is understandable, but a simple price war is unwise. 2013 or more competition at the low end of the price competition, the real competition in the market should be the corporate brand strength and product quality. For example, the TV industry has reached a certain stage of maturity, brand competition becomes more apparent, the combined effects of enterprises will affect the brand consumers to buy the product.
The overall development of commercial led high bay lighting wholesale face facing the "bright future" and "grim facts" coexistence, we want to develop industry confidence. LED display applications with the development of basic industries should be said that for many years, in terms of product technology, marketing network, and application markets such as professional team has a good accumulation, constitute an important cornerstone of the development of the industry. More importantly, China's LED display applications industry is rooted in the market developed, the industry of private enterprises as the mainstay, with little government support and preferential wild may mean more vitality.

LED lighting lamps are more and more popular in our daily life especially the led car lamps

For a car, the headlights if it ‘s “eyes”, while nowadays energy saving, environmental protection, the volume is smaller Europe led street light fixtures manufacturers
become a popular decorative element of the car. For example, LED headlights, LED brake lights, LED down lights , LED strobe lights, LED daytime running lights and so much the young owners of all ages. For automobile manufacturers, are now starting to assemble only to high-end models of LED lights to extend from low-end models, such as Guangzhou Honda Ling faction, the new Dongfeng Fengshen S30 and other models, this will undoubtedly enhance the product selling point. Although the LED lights dazzle, cool, but its maintenance costs compared to traditional lights are really expensive to, if the owners themselves be modified, but also pay attention to annual eligibility, and harness coarse enough, not to vehicles and driving safe to stay hidden.
“LED lights has become a major concern when consumers buy cars, especially the young consumer groups, would ask when buying a car.” Marketing Manager of Dongfeng Fengshen a 4S shop Sunguang Ji Jilin Yong told reporters, “LED daytime running lights began to move toward the civilian population, the original can be seen only in the Audi, BMW, Volkswagen and other imported cars, many cars are now running on the road are equipped with. “However, for many young car owners, the use of LED daytime running lights up to be caught up in the trend now, but not really leading the trend. “I have replaced the entire headlight LED lights, including brake lights, headlights, turn signals, daytime running lights, absolutely dazzling.” Liu said with a smile after 90 owners.
Culture News bikers club modification enthusiasts Wang said: “In fact, in addition to cool modified Europe led street light fixtures manufacturers, you can also ensure road safety, for example, modified vehicles LED daytime running lights in the daytime sun glare or eye than the rain and fog days the more the difference is recognized in the case of other vehicles. ”
Although the LED lights dazzle, but its high maintenance costs and allows owners who refer to “injury can not afford.” According to the city of Changchun Qi Mao Zhao auto parts store owner introduced: “LED lamp shape not only dazzle and brightness LED headlamps than xenon headlights, light, fast response, but the price is relatively high, for example, Mercedes-Benz, BMW and other luxury models LED headlamps, prices are ranging from 20,000 to 80,000 yuan, the owner, is not a small burden. ”
Recently, Xiao Song riders in their car on the chagrin of thousands of maintenance fees. Reporters learned, Xiao Song driving a luxury car brand LED turn signal is broken, to the 4S shop maintenance was found to be burned out. “Originally thought to replace a light bulb on it, hundreds of pieces of things, but the mechanic told me the LED turn signal bulbs can not be replaced separately, broken entire assembly will need to change the price at around $ 2000. “Xiao Song frustration said. And Xiao Song have the same experience as well as a joint venture brand owner Mr Zhao:. “My LED brake lights are not bright, was asked to go for a 4S shop assembly, cost nearly 1,500 yuan, go outside repair shops offer also thousands million, or think about the first ordinary halogen bulbs cheap ah! ”
It is understood that many car owners like DIY, Europe led street light fixtures manufacturers which make alterations young owners of a few, but in the self-install LED lights have a lot of attention to the matter GAC Toyota 4S shop service department supervisor, said Liu Ying.: “Europe led street light fixtures manufacturers is actually a light-emitting diode, is a single conduction, longevity, energy saving, low heat, low voltage light sources, especially in the choice of LED lights. pay attention to the thickness of the wiring, the wiring harness is recommended to choose thick, so you can ensure that the process is not easy being burned, while the installation should pay attention to the alignment of concealment, not too much to bare, exposed, to avoid a security risk in addition, factors that influence efficiency and lifetime LED car lights are mainly temperature, so the owners want to modify LED lights, it is recommended to select good thermal performance of LED lights, and pay attention to the installation process for future LED lights surrounding environment thermal environment. worth mentioning, modified car owners must not destroy the original car’s appearance, once changed the appearance, then there will be trouble when the annual inspection.

The main development trend of LED lighting technology

LED lighting for its high efficiency, low energy consumption, long life, light, etc, and gradually replace the incandescent lamp, are widely used in various fields. Over time, the market also presents new challenges for commercial led street lighting wholesale, environmental sensitive and intelligent modular design has become the main trend of LED development.
At present, the characteristics of the LED has been significantly improved, LED downlights and retrofit bulbs already have a higher luminous efficiency than existing technologies (incandescent, halogen and compact fluorescent lamps); LED next few years will continue to decrease costs, may reduce the cost of LED bulbs and lamps; compared with the 2010 study, LED prices have accelerated decline (down 13-24% per annum).
On the policy side, many countries have introduced policies to encourage the development of LED lighting industry. For example,
commercial led street lighting wholesale and Reform Commission recently issued the "semiconductor lighting energy industry planning", plans to 2015 functional LED lighting products market share of over 20%, LED lighting energy industry output growth of around 30% in 2015, with an annual output value of 450 billion yuan ($ 72 billion); Moreover, by 2015 more than 60W incandescent bulbs for general lighting will be fully eliminated.
A wide range of general lighting power, LED general lighting include: Residential (3W-15W), as 60WA-19 bulb 800lm 's; business and building decorative lighting (15W-75W), such as the 2,800 lm 4 feet long T8 lamps ; outdoors and infrastructure (75W-250W), such as a 150W metal halide 13,000 lm.
These LED drivers encountered many challenges: energy efficiency is critical, because the fixed bulb shape can lead to heat is limited; limited space inside the bulb, the need for greater heat sink area is particularly true of high power bulbs; LED is rapidly changing, with many choices; drive electronics must be reduced to increase the space to the constituent material; drive needs to be optimized to cope with different lighting and power requirements.
LED driver challenge there LED configuration (LED quantity / drive current) influence the choice of topology; bulb type on heat sink design, and greatly affect the system options, such as energy efficiency targets, the available space; influence the choice of isolated or non -isolated topologies the factors include: LED selection, safety, mechanical design know-how and technology; LED manufacturer of rapid innovation, the introduction of new LED configuration and design (high-voltage LED / multi-LED package).
In addition, determine the characteristics of
commercial led street lighting wholesale can achieve "smart lighting" advantage, because the LED is easy to control and dimming; electronic circuit to increase the variety of new features, such as built-occupancy (occupancy) sensor to adjust the brightness according to the ambient light to province electricity, wireless interface without changing the switch or cable;. saving technology and the convenience and safety However, the "smart" lighting requirements AC-DC LED driver IC must be designed to easily fit analog and digital (PWM ) dimming; using low-power wireless interface, such as IrDA infrared, ZigBee and Bluetooth low energy (Bluetooth LE); Wireless Control standards in place, such as ZigBee Light Link; to measure ambient light and easy to use device to detect human activities .

commercial led street light

The region of maximum of global lighting energy consumption especially the LED lighting including the commercial led street light and other industrial and commercial or household LED light is North America, Europe, China, the total of proportion is 60.6%, showing the three areas are the main markets in the lighting industry.
high power LED flood light high power LED flood light
However, if observing the proportion of the world's major regions where the LED lighting distributes, the highest will be in Japan in 2014, which will be 25.6%, largely the penetration rate (in value dollars) of commercial led street light and other commercial or industrial and household LED light will reach 65.6% in the area, however what should be note is that the future growth potential in the area will be slow, DIGITIMES Research estimates annual growth of
commercial led street light and other commercial or industrial and household LED light in 2014 will be 22% in Japan, which will be more than 40% lower than that of the annual growth rate in North America, Europe, and38% lower than value of annual growth rate of the output of global high power LED flood light and other commercial or industrial and household LED light.
DIGITIMES Research estimated that the proportion of the total of share of global commercial led street light and other commercial or industrial and household LED light in North America, Europe, China's three areas will reach 59.4% in 2014, an increase is 2.4 percentage points compared to 2013, but decreased by 3.4 percentage points in Japan. Why the global LED light grow in the aforementioned three areas mainly because that the original focus of product line of the commercial LED light including
commercial led street light gradually turn to consumer market, the traditional lighting plants enhance the proportion of LED product line, the Chinese mainland government continues to invest resources on the LED lighting project.

The safety research of LED car headlamps optical radiation

 
led street lighting fixtures

Radiation hazard has been one of the four major environmental World Health Organization (WHO) is clear and led street lighting fixture parallel security problems facing humanity . Optical radiation is an important part of the radiation is radiation exposure bands most closely with humans. Light sources and lighting radiation safety research in the field of optical radiation on the human body is mainly injury problems.

       
Optical radiation hazards include ultraviolet, visible and infrared light radiation on human tissue damage , primarily in general the study eye and skin. Eyes are one of the most important sensory organs of people , its structure is very complex, and self-repair capability is weak , the most vulnerable to optical radiation damage , such as Blu- prone too strong photochemical damage photoreceptor cells in the retina , too strong thermal radiation can cause retinal thermal injury. Optical radiation wavelength region and the role of the correspondence between the eyes in Figure 1.

   
In recent years , the rapid development of international biological research glazing , especially in the third through the study of human non-visual cells in 2002 , the impact of basic research on optical radiation circadian rhythms and endocrine systems , people use and potential sources the problem more seriously. Disorders of several known main cause optical radiation hazards are : light induced and light-induced conjunctivitis, keratitis , cataracts , retinal burns, blue retinal damage, skin tanning , ultraviolet erythema , skin aging , skin cancer and the like.

 
ICNIRP exposure limit recommendations based on the assessment of the biophysical data, and publishing guidelines for optical radiation safety aspects of non-coherent light source and the laser beam. For LED, ICNIRP recommends following the guidelines of non -coherent light source.

 
CIE Division VI established the appropriate technical committee to study the LED light radiation on the human eye damage evaluation. 2002 issued biosafety standards for LED light and other non- coherent light source
led street lighting fixture, and the recommendation to the IEC standard as the industry standard.

 
Since 1993 , optical radiation safety requirements for LED products were included in IEC 60825 " Safety of laser products ", the laser products as required to regulate . But LED and laser different, so in 2007 published IEC 60825-1 " Safety of laser products - Part 1 Equipment classification and requirements" in the second edition , LED products are no longer in accordance with the laser product to consider. October 2008 meeting held IEC/TC76 formally decided to optical radiation safety for all

How to improve the products quality by LED street light manufacturer?

The author on a certain understanding of the development of foreign trade marketing for LED street light manufacturer, a bit of development through a network e - mail clients, this type can be considered for foreign trade promotion, the strength of enterprises seeking local dealer.
But the industry also have feedback, LED technology continues to mature and the application of market expansion, but now instead of bad done.
LED street light manufacturers are mainly in the foreign LED street light manufacturer, there are several major shortcomings, the first to face the problem of falling prices, market products T8 tube, for example, in 2010, priced at 120 yuan, but now 73 yuan buy into, and the product or market popular one of the products, as companies competing to sell the product, the market space becomes obvious being squeezed.
Low energy consumption: The much lower energy usage of LED lighting can dramatically reduce operating costs.
    
Long and predictable lifetime: The lifetime of LED street lights is usually 10 to 15 years, three times the life of current technologies adopted The much less frequent need to service or replace LEDs means lower maintenance cost ..
    
More accurate color rendering: The color rendering index is the ability of a light source to correctly reproduce the colors of the objects in comparison to an ideal light source Improved color rendering makes it easier for drivers to recognize potential road hazards ..
    
Quick turn on and off: Unlike fluorescent lamps, which take time to heat up once switched on, LEDs come on with full brightness instantly Unlike mercury vapor, metal halide and sodium vapor lamps (commonly used in street lighting),
LED street light manufacturer do not have. a problem restarting immediately (hot ignition) following a brief power failure or inadvertent turn off.
    
RoHS compliance: LEDs don't contain mercury or lead, and don't release poisonous gases if damaged.
    
Less attractive to nocturnal insects: Nocturnal insects are attracted to ultraviolet, blue and green light emitted by conventional light sources.
    
Fewer electrical losses: All other types of lighting (except incandescent) require ballasts, additional electronic and / or electromagnetic components, in which some power is consumed.
    
Optically efficient lighting equipment: Other types of street lights use a reflector to capture the light emitted upwards from the lamp Even under the best of conditions, the reflector absorbs some of the light Also for fluorescent lamps and other lamps with phosphor coated bulbs, .. the bulb itself absorbs some of the light directed back down by the reflector. The glass cover, called a refractor, helps project the light down on the street in a desired pattern but some light is wasted by being directed up to the sky (light pollution ).
LED street light manufacturer assemblies (panels) do not require reflectors and can be designed to provide the desired coverage without a refractor.
    
Reduced glare: Directing the light downward onto the roadway reduces the amount of light that is directed into driver's eyes.
    
Higher light output even at low temperatures: While fluorescent lights are comparably energy efficient, on average they tend to have lesser light output at winter temperatures.

LED life is decided by the power of the number of passes a certain threshold number of hours, LED bulbs will be time to gradually reduce the light output.
The new product detected by LM-80 is helpful. led high bay light for sale will gradually turn darker and burned directly. And the other provisions of the lumen which is lower than the original 50% will be no longer used, Inappropriate temperature, The second chapter. LED lights inside pointed that the cost of the LM80 test project is much high, but also even better performance. the number of lumens is still higher than 70% of the original light output by the detection of the LED samples, a requirement of bulb lumen less than 70% of the original is not suitable to continue to use,
For example, (and the light dimmed to how much the phase-out). The first standard (L70) is adopted to general lighting
led high bay light for sale for home. How to help the buyer to select the most suitable LED lamps for home?
LED lamp life is very long, while the second standard (L50) is used a decorative LED lighting. A LM-80-08 Detection of LED lamps for home and claimed more than 30. That is the reason why the test price of LM80 is so high, But unlike other bulbs. Like other light bulbs, 000 dollars. Which means that passing LM 80 is not only reached the basic light fades requirements.
LM-80-08 manual referred to two different standards adopted by the industry.000 hours, The manufacturers who can afford to do this are generally medium-sized and large companies.000 hours, The reason is that it should light up thousands of hours to do the light fades test parameters and precise information, Both LED life standards developed by the Lighting Research Center of the solid-state lighting systems and Technology Alliance Team (ASSIST). power and water vapor is the main cause to destroy the
led high bay light for sale and determine the LED life factors,
IES another manual guide about LED light source and module -. LUMENS-80-08 Measuring Lumen Maintenance of LED Light Sources specifically develop a detection LED life of the program but it will take a longer time to do the detection because the integrity of the testing process needs to spend 6.

LED lighting design become a big challenge of Autocar heat managment

Nowadays, more and more electronic devices are being widely used in the automotive industry. Statistics show that today 's electronic devices in a car costs accounted for 30% -40%. These electronic devices include not only the engine control unit, brake system control unit and transmission functions of the apparatus and more electronic products, such as entertainment and navigation systems. Recently, the use of france led street lighting factory technology for the automotive sector there has been explosive growth, for example, in Europe, all cars must install LED running lights.
LED will continue to emit heat, and shade has become smaller and smaller. Brightness and power consumption rising, but was closely aligned with the LED (front and rear lights) was not equipped with the appropriate cooling fan. Therefore, reliability and performance is bound . to be affected If the LED junction temperature exceeds a critical problem arises: LED lights dimmed If the temperature continues high, LED lamp life will be shortened, then premature retirement The average life expectancy of LED lights on the car has thousands of hours.. , early retirement will bring additional manufacturer warranty costs.
Excellent thermal management depends on good thermal design. As shown in Figure 1, LED elements are designed in the first part of the process. Element using thermal analysis software designers and test equipment for the material and structure of the element analyzed, ensure that the heat generated on the junction can be easily comes out through the LED element layer. Subsystem designers will LED elements arranged in an array, and add radiators and other cooling devices, and then analyze the product again. They may adjust the spacing between the LED elements, or add additional cooling devices to ensure that the LED does not exceed the critical temperature. The final step is usually a mechanical design engineer with mechanical computer-aided design system to complete, the designer will line up of LED lights into the shade (such as car headlights) years, while the use of advanced computational fluid dynamics (CFD) software for thermal analysis.
So where is the problem? Over the years the industry has been using excellent CFD thermal analysis software. FloTHERM other products fast, precise and very easy to use, and requires no external experts, engineers within the company will be able to complete the analysis. But the problem is that the accuracy of the results of software, depending on the input components model accuracy. If the component model input is not accurate, regardless of how perfect the process of analysis, the results will only mislead the software designer.
But the key is a typical LED data sheets provided by suppliers, will only be a single thermal resistance of its total power consumption (such as maximum forward current and voltage), and the "knot" and some reference points (such as welding points) between and how the package without the heat and dissipate information layers, the layers are not able to be used to define the thermal resistance and heat capacity of the path / obstacles description.
In this way there will be any problems? Typically, thermal management experts estimate the internal structure of the package, and creates a thermal model to describe the thermal resistance and heat capacity of each layer and the circumstances of each structure. This model is a few percentage points as long as the deviation occurs, it will result in inaccurate analysis, but does not verify or determine the quality of the thermal model of such a method.
So fundamentally speaking, we still have gaps in the designed cooling systems. In all aspects of product development (components, subsystems, and the entire system), the thermal analysis must not be less, but only under favorable circumstances component thermal model, it is possible to obtain good thermal analysis results. Without knowledge of the internal structure of the package components, we can not define or verify the accuracy of the model, and component suppliers usually do not divulge intellectual property in this area.
The solution is simplified by defining and validating components of a thermal model shown in Figure 2, the establishment of a "bridge" between the hardware test / measurement and thermal analysis. Existing hardware element is capable of measuring the parameters of a heat dissipation characteristics. With sophisticated software, these measurements can be converted to the simplified thermal resistance and heat capacity network, we can read the simplified network model of the thermal analysis software.
For example, Mentor 's T3Ster hardware components coupled to the test, you can measure the transient junction temperature changes, either heating or cooling elements, can be accurate to 0.01 degrees Celsius. In the heat dissipated to the surrounding environment from the end of the process, can be collected in one minute to transient changes over ten thousand data points to describe the junction temperature, and transient characteristics of the junction temperature, says the components of each layer thermal resistance and heat capacity situation. With these data, using the analysis software automatically generates LED simplified thermal model. An accurate and efficient model was born.
france led street lighting factory in the design, can use this technique to measure the thermal performance, and optimize it, and then again for our customers measure and create a thermal model. Subsystem and system developers can use it to verify the thermal model obtained from the vendor or supplier does not provide in the case of the model to create a model yourself. The reliability of electronic equipment design margin is very small, design responsibility usually falls upon vendors wife, warranty and recycling issues will directly affect their profit and loss, so they need to confirm their own product design hundred percent no problem.
In the thermal resistance -. Heat capacity chart, the blue line represents just produced LED, other lines denote used 500 hours, 2000 hours and 3000 hours of LED Seen by the horizontal direction, a layer of high thermal resistance used to represent the line of LED, which shows that the position of the case material separation occurs, the thermal conductivity of air is much smaller than the original material. This type of fault diagnostic tests can be used for LED and IC package.
The second application is in the production process. In the production of LED, glue thickness and other parameters is not fixed, so it can serve as an important test instrument production line of a ring. First sampling, testing and then quickly make comparison with standard devices quickly able to find deviations in the production process, and thus give correct. ROI The test equipment is very impressive. So, now
france led street lighting factory and original equipment manufacturers responsible for subsystem and system development, you can use a precise components to complete the design , application and failure analysis (Figure 4) of the product.
Figure 5 shows the auto industry 's supply chain, we see that the supply chain in addition to automotive original equipment manufacturers, as well as secondary and primary suppliers. Have good thermal design thermal analysis, one and two suppliers designers need to have this capability . This thermal physical analysis by accurate and timely test to heat the measuring element, subsystems and systems to support and verify. Automotive original equipment manufacturer can prove is that they are buying products with high reliability and low power 

 consumption performance.
