LED light market situation and future development

Many people think that high-tech LED industry, mainly concentrated in the epitaxial wafers and chips upstream, midstream and downstream areas of neglect also have a high technical content and level of application of proven industry precisely because of the rapid development of middle and lower reaches, is promote development and progress of the upper reaches of power. 863 major projects the overall semiconductor light expert experts, PAN Jian, vice chairman of Zhejiang Province, the root Illuminating Engineering Society pointed out that "China‘s LED industry is driving the upstream downstream to upstream to promote the development of application markets." At present, China has initially formed, including LED epitaxial film production, LED chip preparation, LED chip, LED packaging, and product applications, including a relatively complete industrial chain, and in the downstream integration of applications with some advantages. LED number of employees up to 5 million people, more than 20 research institutions, enterprises more than 4,000; one upstream firm more than 50, more than 1,000 packaging companies, more than 3,000 enterprises downstream applications. Driven by the huge domestic demand, LED industry, prospects for the future.

In the LED industry, from the LED epitaxial wafers to the end of the applications, need to go through material epitaxy, chip making, die packaging, application design and assembly of a series of industrial chain links, the chip is just one aspect. On the one hand, from the wafer, the package to the light, display and backlight, and other applications, all aspects of the industry chain can form a separate product, and have their own technical barriers and research needs; the other hand, the quality of end-applications will be the impact of each session. With the application of technology becomes more mature, LED light applications technology enables the semiconductor light efficiency, light quality, innovative design and other aspects of advantage relative to traditional light sources, semiconductor light and constantly open up the market. The expansion of markets will lead to production expansion and increasing industry R & D investment to accelerate technological progress, so that performance and costs and prices declined. Therefore, the rapid development of the international LED light market in 2010 is expected to reach 17.449 billion U.S. dollars.

Not to be outdone in the field of LED light in China, China promulgated a number of policies, actively promote the development of LED light market in 2010 is expected to reach 21.661 billion yuan, increased by 35.8% next year.

LED light applications mainly refers to the light manufacturing and control systems, technology more reflected in the system design, structural design, heat treatment and two or three times optical design. In fact, many LED light companies in technology are a headache for this product to solve the heat problem, the light fades how to solve and so on. Application of the final product is the touchstone of all the technology. For example, the core component of semiconductor light is LED chips, but the luminous efficiency of LED chips 100lm / W, does not mean that the efficiency of semiconductor light also reached 100lm / W; more importantly, semiconductor light products to gain market recognition including light efficiency, reliability, comfort and other human eye, including the overall performance compared to conventional light products must have a clear advantage. In other words, even if the efficiency of semiconductor light reach 100lm / W, does not mean that it necessarily accepted by the market, semiconductor light itself, there are many scientific issues need to be studied, such as light effects and quality, including color, color product consistency, such as the human eye comfort. Currently, LED street light technology is relatively mature, compared to traditional lights, have obvious advantages, have been gradually accepted by people in the world to promote, the international LED street lamp market increase every year and 2010 will reach 261 million U.S. dollars.



According to statistics, China‘s LED light s during the first half of 2010 sales reached 462 million yuan, is expected to sell 693 million dollars in the second half. Year to reach 1.155 billion yuan. By the "Ten City, ten thousand" and other policy driven, this year the installation of LED light s steadily in fact a substantial amount of growth, an increase of 118.74% or so.
