Industry analysis: from fast to stable LED over the past ten years

2003 China's total output of 20 billion LED, after the development of the industry for the past ten years, the domestic epitaxial and chip manufacturers to nearly a hundred, in 2011 the annual output value of LED was $156 billion, of which epitaxial and chip part of the output value of 6 billion 500 million yuan.

10 years ago, had almost been marginalized LED industry, relying on the emergence of blue light and high-power technology breakthroughs, as well as strong policy support, ushered in the booming spring. At present, LED industry has become one of the most promising new industries, is an important part of the new generation of information technology and energy conservation and environmental protection two strategic emerging industries. 10 years of development, the rapid growth of China's LED industry, technological innovation capacity continues to improve, gradually expand the application field, a number of backbone enterprises grow up, a number of successful listing. Industrial development has begun to take shape, becoming one of the fastest growing industries.

Remarkable results

China's LED industry started in the last century in 70s, the real development in the past 10 years. 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, the Ministry of finance has also increased investment in the LED industry and applications. Driven by the ministries, China's LED industry has made rapid progress, the industry has maintained a growth rate of around 30%, by 2011 the total industry output value of $150 billion. "Since 2003, the domestic extension and chip companies only Xiamen, Dalian Road, Shanghai three beautiful blue, Blaupunkt, Shandong, Jiangxi, Shijiazhuang Hua Yan Lei 13 more than a dozen companies. 2003 China's total output of 20 billion LED, after the development of the industry for the past 10 years, the domestic epitaxial and chip manufacturers to nearly a hundred, in 2011 LED output value of $156 billion, of which epitaxial and chip part of the output value of 6 billion 500 million yuan. "Invenlux optoelectronic (China) Limited company president Dr. Yan Chunhui told reporters.

In the scale of the industry to maintain rapid growth at the same time, the technical level also significantly enhance the luminescent efficiency, production increased to more than 110lm/W, with the international advanced level is shrinking; development of packaging technology to flip, integrated package, close to the international advanced level; independently developed metal organic source, sapphire usedwidely, metal MOCVD prototype development success. In particular, China's silicon (silicon substrate) LED technology and industry breakthrough. Nanchang University, National Engineering Research Center for silicon-based LED at the current density of 35A/cm2, the silicon substrate blue LED devices electro-optic conversion power efficiency reached 50% ~ 55%, packaged cold white LED devices, the luminescence luminous efficiency reached 120lm/W ~ 130lm/W, reached the mainstream level sapphire LED. Under the current density of 5A/cm2, the conversion efficiency of the blue light LED device on the silicon substrate is 55% ~ 60%, which is packaged into a cold white LED device. The luminous efficiency of the device is 145lm/W ~ 160lm/W. Small size (0.2mm * 0.2mm) chip to power type chip (1.1mm * 1.1mm) have achieved small batch production, were used in color screen, digital tube, flashlight, bulb, lamp etc.. Up to now, China has been in the international leading position in the two aspects of silicon-based LED research and industry.

Policy help

LED industry is the main content of the national strategic emerging industry in recent years, the state has adopted a number of policies to encourage the good momentum of development of the current industry, is inseparable with the introduction of relevant national policies to encourage the development of the industry. To support the development of LED and semiconductor lighting industry, the State Council, the national development and Reform Commission, Ministry of industry and information technology, Ministry of science and technology and other relevant ministries in technology innovation, technology upgrading, encourage the application and other aspects of long-term give priority support.

Anhui Zerun photoelectric Limited company president Chen Hesheng said in an interview with reporters, support for the LED industry, all levels of government agencies, from investment to support the market application supporting. "The State Council released the latest energy-saving LED lighting products subsidy mode, down to the current local government gradually MOCVD production line investment subsidy mode to support enterprises in the region of the regional new energy-saving LED lighting market to occupy, are used to promote the end of evidence has been replaced by the investment side drive has become the main way of supporting the LED industry the development of this industry development is not only a transition of the important symbol, also means that on the eve of the LED lighting market has reached mass market applications. Chen Hesheng said.

As an important measure of the transformation of economic development model, industrial restructuring, LED and semiconductor lighting as the key content, included in the national strategic development of the proposed seven strategic industries. In May 16th this year, the executive meeting of the State Council decided to implement energy-saving Huimin project, the state financial subsidies for 4 products, including efficient lighting (including energy-saving lamps and LED lamps). July 19th national development and Reform Commission released the 2012/2013 fiscal subsidy policy to promote semiconductor (LED) lighting products. For technical innovation and technical support of LED and the progress of semiconductor lighting, the Ministry of industry and information technology for many years for electronic information industry development fund project, as an important measure of independent innovation in support of LED, used to break through the key technology, technology development, test method development and service ability and so on, and achieved remarkable results.

At the same time to see the results, we also need to recognize that the bottleneck of the development of the industry under the new situation is also very prominent. In the short term, the industry appears stage and structural overcapacity. For a long time, the core technology of industrial development has not yet made a fundamental breakthrough, the industrial structure
