The total output of LED products in 2003 is about 20 billion. After ten years development, there are nearly 100 manufacturers for LED epitaxial technologies and LED chip technologies in China. The annual production output of LED products in 2011 is around 156 billion yuan, 6.5 billion yuan is from LED epitaxial industry and LED chip industry.
10 years ago, LED lighting industry narrowly avoided the tragedy of marginalization. Replying on the emergence of Blue-ray, breakthroughs of high-powered technologies and great supports from the government, LED industry ushered in the spring. Currently, LED-related business has become of the most promising industries in China, an important part of information technology and energy-saving strategy. After 10 years of development, China’s LED lighting industry rapidly grew. Technological innovation capabilities continued to improve. The field of application gradually expanded. The entire industry chain has begun to take shape and still running forward at an amazing speed.
Domestic LED industry started in the 1970s, but the real development happened in the past 10 years. In 2003, the Ministry of Science and Technology, the Ministry of Information Industry, the Ministry of Education, the Ministry of Construction jointly organized the implementation of the National Semiconductor Lighting Project. Followed by the National Development and Reform Commission and the Ministry of Finance, who increased the investment in LED industry and application. With great supports of the government, the LED industry in China has made rapid progress, the scale of which has maintained a growth rate of about 30%. In 2011, the annual output value of LED products was 150 billion yuan.
The technical level also significantly improved with the rapid growth in the industrial scale. The luminous efficiency has been improved from 85lm/W in 2003 to current 110-140lm/W. The gap with the international technical level is narrowing. The packaging technology is heading to flip / integrated direction, much close to the international advanced level. A number of large LED enterprises successfully developed organic LED Panel Light sources, sapphire substrates and MOCVD models. Our silicon (silicon substrate) LED technology and industry has achieved a breakthrough. Nanchang University National LED Engineering Technology Research Center has successfully produce silicon substrates Blue-ray LED devices which could realize an electro-optic conversion of 50%-55%.
