Depth analysis: opportunities and challenges for LED lighting in China

"Low carbon era China LED lighting field is coming, as the traditional lighting system energy consumption will be replaced by LED lighting has become an indisputable fact. Over the years, China's LED industry from scratch, from small to large, from social to society attaches great importance, even woman and children all know has achieved great development. At present, it has formed a complete industrial chain, such as epitaxial growth, chip manufacturing, packaging, application, testing and standards. China optical photonics industry association, said Yang Kewu, chairman of optoelectronic devices branch. 2009 global LED market value of $8 billion, China LED application products reached 60 billion yuan, in 2010 China's LED industry output value will be more than $150 billion. From the field of electronic information into the field of lighting for the LED industry to provide a broader market space and innovative space, has become the focus of the current industrial development. With the development and progress of technology market and policy support, Chinese LED industry is experiencing from the pupa metamorphosis, the transformation process is painful, but the result is beautiful.

Favorable policies promoting industry development

LED lighting is a new strategic industry, policies and measures have been introduced for the industry to create a good environment.

In December 30th last year, the national development and Reform Commission, Ministry of housing and urban rural construction, Ministry of transport and other three ministries in Beijing jointly organized the demonstration project of semiconductor lighting products will work. Some experts said that this is the 2007 Ministry of science and technology, ten city million to promote a continuation of the street lamp demonstration project. Although the Ten City million light reflects some problems, but it can not be denied that the Ten City million lights on LED lighting a huge role in promoting. The selected 20 semiconductor indoor lighting applications project, 15 projects and 15 semiconductor lamp applications semiconductor tunnel lamp application project, three categories of products, the 28 listed enterprises and product specifications, delivery price agreement was determined by the unified bidding. One of the finalists of the crystal energy photoelectric stakeholders said that the tender for the promotion of LED lighting products and LED lighting market norms are of great significance.

LED lighting industry is a new strategic industry, in recent years, the development of this industry in China has given high priority, both at the national level or local level, have introduced a lot of support for product development, technological innovation and application promotion policies and measures, to create a good environment for the development of the industry. The national development and Reform Commission, the Ministry of industry and information technology and other six ministries in September 2009 jointly issued "on the issuance of the opinions of the development of semiconductor lighting industry notice", in October 2010 the State Council issued on accelerating the fostering and development of strategic emerging industries, decided to clear the present focus on fostering and development including energy saving and environmental protection, new generation information technology, biology and high-end equipment manufacturing, new energy, new materials, new energy vehicles and other industries. In these seven industries, semiconductor lighting materials become one of the strategic emerging industries in the field of new materials to achieve rapid and healthy development.

According to incomplete statistics, there have been clear construction of semiconductor lighting industrial park in 14 provinces and municipalities, the LED industry as an emerging industry in the region to develop. In the "863" plan, the electronic development fund, the ten major energy conservation projects, demonstration projects, high technology industry technology upgrading and structural adjustment and other special support, gratifying progress has been made in China's semiconductor lighting technology development and industrialization. According to Industry Association statistics, China's semiconductor lighting industry in 2009 sales value reached about 80000000000 yuan, an increase of 30% contrarian above, this is also in the international financial crisis is one of the few to maintain high growth industries, China has become one of the global semiconductor lighting industry the fastest growing region, but also a very the important manufacturing base and application market.

Upstream breakthrough to becoming a complete industrial chain

Formed epitaxy, chip, packaging and integrated application of R & D and relatively complete industrial system, laid the foundation for the LED industry bigger and stronger.

"China LED epitaxial material, chip manufacturing, packaging, phosphor and other areas have appeared with the independent property rights unit technology, part of the core technology with originality, initially formed from the upper and middle materials chip preparation, downstream device package and the integrated application of relatively complete industrial system and development do, laid the foundation to a certain extent for China's LED industry bigger and stronger. Chinese Academy of Sciences, said Li Jinmin, director of semiconductors.

LED long industrial chain, including substrate material, epitaxial growth, chip manufacturing, packaging and application products and related equipment, materials and other key sectors, including profit and technical content is the highest in the substrate epitaxial chip. According to Industry Association statistics, in 2009 China's LED enterprises of nearly 4000, the output value of 82 billion 700 million yuan, an average annual growth of 20%, the upstream epitaxial, chip industry in 2009 the output value of $2 billion 300 million. China's LED chip industry from scratch, the annual growth rate of 25%. Especially the breakthrough through the silicon substrate LED technology innovation developed by Professor Zhang Wansheng, China Electronics Technology Group thirteenth said that the semiconductor lighting R & D center and the national quality supervision and inspection center of Jiangxi semiconductor crystal company sent a group of (100) silicon substrate 1mm * 1mm power type chip was tested. The test results are encouraging, 350mA, the peak wavelength of 450nm, radiation power is more than 350mW, the highest level of domestic power chip. "This is our country
