The development prospects of the mainland State LED (2)

The development process from the LED industry, the global sales of LED according to the market is currently the largest mobile phone backlight market, with mobile phone sales growth slowing down, as well as the OLED screen on the mobile phone TFT-LCD screen to enhance the penetration of the global growth rate of the LED . Technological progress as a result of cost reduction in the current (and even pre-2010) is not enough to allow full access to general use LED lighting market, global growth will be the next notebook, LCD TV backlighting, and automotive markets with the car interior lamp backlight market. As the world's top five LCD panel (LG Philips, Samsung, AUO, CMO and Sharp) in a high level of LED technology, large production capacity in Japan, Taiwan and South Korea, domestic only BOE, polish electricity and the Five Dragon PV panels of three lines, the 4.5-generation Shanghai Tianma production line will be able to after the demand for LED backlighting, but the overall demand is not dominant, the domestic enterprises to enter the LCD panel backlight LED supply chain proceeds should not be too large backlit panel with mobile phone market is quite similar.

Application of the Chinese market at this stage mainly in the architectural lighting, indoor and outdoor display, based on the above reasons, the main force of the next wave may be present in these markets, but in mobile phones, small size LCD backlight, automobile penetration will increase, and some scattered markets such as special lighting will open up even more (the cost of special lighting requirements for general lighting is not so harsh). After the replacement of a few years ago, LED traffic lights is very popular, as the LED's life is longer, the short term it is very difficult to replace in the event of large-scale work, which makes the LED traffic lights for a period of low demand period ; a large domestic sedan market, but higher, certification cycle length, as long as there is excellent product quality, domestic motor vehicle lights LED backlighting and a very large market demand and growth in demand in this market is relatively stable; and LED display its easy to assemble, low power consumption, high brightness, etc. has been widely applied to the banking, securities, squares, railway stations, sports venues, the future of this market there is still great potential for growth; in the Olympic Games, World Expo, a number of city night demonstration effect of the project, led by National Semiconductor Lighting Project, as well as the many favorable factors, such as the promotion of, the architectural lighting market is still a broad prospect.

The development prospects of the mainland State LED(1)

LED doomed its huge market will develop into a huge industry. Overall, the domestic industry in terms of size has been unsatisfactory, the typical case is the integrated circuit industry and the LCD panel industry, the domestic IC industry is now tail between its people, LCD panel industry is riddled with illness, technology complex, large investment and a weak infrastructure is the main reason, while the LED industry will break the curse, and can bring about the upgrading of industries, such as the domestic industry in LCD driver chips simply do not drive, because the LCD panel industry out of the country, support because of huge market, LED Driver IC is expected to flourish in the country to promote domestic enterprises bigger and stronger, which in turn will promote the domestic LCD driver chip or other chip-driven development.

We believe that the LED industry in China has good prospects for development, based on the following points: First, in terms of the technology, LED technology has the bottleneck of high growth, low-threshold characteristics of the study, the domestic long-term accumulation in the semiconductor field of research resources can be useful with a good basis for further study. Although the manufacturing of integrated circuits based on weak, relatively low technological level, but some domestic enterprises to join overseas technical personnel, continue to make breakthroughs in technology, technological level of domestic enterprises with good companies with the technological level of Taiwan or less the same as with international companies as a whole has been narrowing the gap; Second, LED invested relatively small initial investment will be 100 million plant, the domestic enterprises to enter the threshold of the low, easy to achieve a rolling development and manufacture of integrated circuits and liquid crystal panel manufacturers easily to tens of billions of billions of yuan in investment it is "insignificant" easier access to the domestic enterprises to form industrial clusters, of course, may also lead to vicious competition and to a certain stage of development of market integration; Third, the domestic market great, LED market is the next major general lighting market, the market capacity, end-consumer market, scattered and difficult to form a monopoly, a vast living space of domestic enterprises; Fourth, some companies have a core of intellectual property rights, such as crystalline silicon photovoltaic substrate can GaN-ray projects, Dalian Road, the area of the United States and the core of the chip technology, has global competitiveness of these enterprises on technology development in the demonstration effect easy to form and promote the healthy growth of the domestic business market; five, after maturity of the technology, LED downstream packaging and devices are labor-intensive production, the development of the mainland with the labor cost advantage.

An LED luminaire is in many ways more complex than a traditional lighting fixture. It is an electromechanical system that includes, in addition to the essential light‐emitting source, provisions for heat transfer, electrical control, optical conditioning, mechanical support, and protection, as well as aesthetic design elements. Because the LEDs themselves are expected to have long life, all of these other components, adhesives, and other materials must be equally long‐lived, or, to the extent they are not, they will limit LED Luminaire Lifetime Recommendations,While LEDs do not radiate heat, with current products half or more of the input energy may be converted to heat that must be conducted away from the diodes. This situation requires a reliable, heat‐conducting assembly, be it mechanical or adhesive, in addition to a heat sink component or means for further conduction. For proper operation, the power supply and electronics must provide a well‐controlled DC drive current and possibly other control features, and must not fail for the life of the product.
Any optical components must be able to withstand years of exposure to intense light and possibly heat without yellowing, cracking, or other significant degradation. Reflecting materials need to stay in place and maintain their optical efficiencies.Even if the design itself has addressed all of these issues, questions of proper manufacturing remain. Was the epoxy properly mixed? Was an essential heat‐transmitting paste omitted? Were the wire bonds properly made? Any of the failure mechanisms inherent in electronic assemblies, and many others, may apply to an LED luminaire. Figure 1, above, is an attempt to visualize this
larger scope of SSL reliability.  For the best lifetime in a well‐designed and properly assembled luminaire, the principal failure mechanism should be lumen depreciation—a gradual reduction of light output from the packaged
LED over time. But other mechanisms could come into play. One LED vendor has reported that the principal causes for customer complaints involve either the use of chemicals in the luminaire that are incompatible with the LED or the driver overstressing the LED. These are design issues, but equally important are early failures of other components or subsystems or manufacturing defects.
These additional failure mechanisms will always persist to some degree and will usually lead to catastrophic failure, but they may sometimes simply accelerate lumen depreciation. An important message of this guide is that these mechanisms must be accounted for in describing product life.

LED LUMINAIRE LIFETIME: Recommendations for Testing and Reporting

UNDERSTANDING SSL LUMINAIRE LIFETIME 
Surprisingly to many, the true reliability and lifetime of light‐emitting diode (LED) lighting systems is currently unknown. Even worse, lumen maintenance values of LED devices are widely used as a proxy for the lifetime of an LED lighting system, which is misleading since light degradation or lumen maintenance is but one component of the reliability of a luminaire. For many manufacturers this approach cannot simply be ascribed to overly ambitious marketing efforts, but rather to dependence on anecdotal numbers in the absence of real data. In addition, we can impute simple ignorance in taking specifications at face value which may or may not live up to claims. It isn't just about the LED. Good LEDs can be incorporated into poorly engineered products and turn the Methuselah of lighting into the exponent of “live fast, die young.” The promise of LED lifetime is often presented in terms of hours and years but with little background data to support anything beyond vacuous promises. The statement of 100,000 hours of LED luminaire lifetime has given way to the realization that there is little consistency, very little published data, and few hard facts around so‐called luminaire lifetime numbers.  The situation is better at the LED package level, where reputable manufacturers have thousands of hours of data under varying conditions. But this is not enough. To manufacturers and specifiers in the solid‐state lighting (SSL) community, the dawning realization is that we need to work together towards understanding the issues surrounding true lifetime and reliability. We need to begin by cataloguing such failures and developing good models for underlying failure mechanisms. This process of understanding and explanation is very common in technological progress. Steam engines existed long before deep understanding of thermodynamic processes.  With LEDs, we have a substantial head‐start on the underlying physics and many years of experience in both lighting and semi‐conductors as well as reliability of related products.
There is no reason not to begin this journey and every reason to start. We will figure this out, find reliability methods and metrics, and learn the underlying root causes of failure. But without data, experiments and models, it is all conjecture. We need a program to drive to reliability metrics.
