As the world‘s most watched new generation of light, LED Street Light because of its high brightness, low heat, long life, non-toxic, recyclable, etc., are known to be the 21st century‘s most promising green lighting. Because of the scope of application of semiconductor lighting is very broad, and with the decline in manufacturing costs and luminous efficiency, the light fades and other technical bottleneck breakthrough. The face of a huge market to be formed, the world‘s semiconductor companies and lighting companies have invested heavily into the semiconductor lighting market, so in countries such as the advance of foreign domestic LED industry has begun to take shape. LED industry development so far, China has become the world‘s largest producer of electrical lighting and the second largest exporter of electrical lighting.
However, the development of the industry chain is still not optimistic terms, led street light upstream industries, including raw materials and substrates, epitaxy and other aspects of the data, including midstream chip production, chip cutting, testing and other sectors, including downstream packaging, and other aspects of the application. At present, China‘s LED industry concentrated in the downstream industry chain, small-scale enterprises, R & D capability is not strong, many companies, large and foreign technology gap.
Owing to the industrial chain, chip making and wafer material upstream production due to higher technical difficulty, plus Western technology blockade against China, the U.S., Europe (mainly Germany) and Japan‘s corporate monopoly in this field, there are Taiwanese companies have a small number of core technologies in this field, in the production aspects of the LED, LED epitaxial wafers and chips production is a crucial step that determines the level of the entire LED industry. The key technology is mainly synthesized Nichia of Japan and Toyota, American Cree (CREE and Philips Lumil lighting in Europe and Osram five vendors monopoly, so there must be a large company developed in the domestic chip field, forge ahead, to form performance and price advantage to make homemade led street light lighting industry to achieve rapid development.
