Signs of recovery in the LED industry have emerged

In March, although the global economic entities still accept a severe test, but after the fourth quarter of last year LED industry downturn, local industrial layout has already begun, although the leading enterprises of the quarterly report has not been announced, but the industry has shown signs of LED recovery.

In recent months, continued to increase the focus on LED International Lighting giant passion, where Cree and China heavily into electric cooperative LED lighting market; MOCVD system service Veeco will use outsourcing; Asian power to opto LED chip market; PHILPS announced the acquisition agreement with Italy IltiLuce company, to further expand in LED solid state lighting market leadership......

Domestic traditional lighting leading enterprises are also actively staking, increase investment in the LED industry. Chinese lighting industry leader OPPLE lighting to be denounced 20 million heavily into the LED industry; KingSun high-power LED street lamp to open up the market in Beijing......

At the same time, local governments have gradually realized the full use of regional resources in support of semiconductor lighting and other emerging industries, the upgrading of traditional industries to develop new industries, the path of development of science and technology innovation, regional economic development is the only way which must be passed.

Optimistic forecast of the industry, the semiconductor lighting industry in the ascendant, the industry is moving toward large-scale applications at that time.

Semiconductor lighting industry is about to become a large-scale application of the crisis in the contrarian strong

With the continuous development of semiconductor lighting technology, domestic lighting power LED device technology in the rapid development of technology and applications. In 2008 China's semiconductor lighting industry output value of nearly 70 billion, chip localization rate of nearly 50%, in 2008 China's LED packaging value reached 18 billion 500 million yuan, up 10% compared to 16 billion 800 million yuan in 2007; the yield from 82 billion in 2007 increased by only 15%, reached 94 billion, which highlighted LED value reached 14 billion yuan, accounting for 76% of total sales LED. In the context of the financial crisis, China's semiconductor lighting industry showed a trend of rising trend.

Although the huge market potential for the semiconductor lighting industry has brought new opportunities for development, but there are also challenges in the opportunity, especially epitaxial, chip and packaging technology and foreign imports of LED devices there is a gap. In view of the current international and domestic industry actual situation, technology we do not improperly belittle oneself, do not blindly arrogant. Domestic and imported LED LED production technology: the highest level of international research achievement report for the United States 161lm/W (4689K color temperature and drive current for the 350mA), China's power type chip and power white GaN LED (1mm * 1mm), domestic chips luminous efficiency of 70-80lm/W@350mA. Standard chip and standard white LED (0.3mm * 0.3mm) luminous power 10-15mW@20mA and white light luminous efficiency 90-100lm/W. Although there is a certain gap compared with foreign countries, the development speed of China's semiconductor lighting industry is the fastest in the world. 2008, the localization rate of China's LED chip has also been improved, reaching 49%, of which domestic small power GaN chip to reach only 13 billion, the localization rate of 41%, but the power of GaN chip localization rate is only close to 20%.

In the field of application of high power semiconductor lighting, domestic LED devices have reached the threshold of 80lm/W lighting applications, 2008 application products in China's output has more than 45 billion yuan, the function of landscape lighting, full-color LED display, solar LED, consumer electronics, signal indication, backlight application is still the main application areas. Landscape decoration, display, home appliances, such as the application market is the largest application market, accounting for about 60% of the share, with the international mobile phone backlight based application market structure is different.

Although there has been some breakthroughs in the upstream core technology, major equipment and application integration, but the main gap semiconductor lighting technology in China's growth, in the epitaxial materials of high power white LED chip production, manufacturing, especially the core equipment and raw materials imported. Although in these areas has invested a lot of R & D, and achieved certain results, but there are still some problems in decentralized, repeated research and development efforts is not enough, and the research mainly tracking foreign technology development, technology originality rarely, the lack of basic level of sustainable development, has not formed the independent intellectual property rights of the patent system.

Semiconductor lighting industry is about to move towards a large-scale application of the domestic market has great potential for LED applications

At present, domestic LED more mature applications including landscape architecture, large screen display, traffic lights, home appliances and digital display lights, car lights, special lighting, mobile phone, digital camera, computer, TV and other small and medium size backlight, the architectural landscape, LED screen display, mobile phone, computer and home appliances and other small notebook the size of the backlight three receiving areas occupy more than 70% market share.

According to the statistics and forecasts, national semiconductor lighting industry alliance development and by 2010, the overall size of the semiconductor lighting market in China will reach 100 billion yuan, LED backlight market scale will exceed landscape decoration, become the largest application field, market scale, functional and general lighting will grow rapidly. Industrial scale is expected to reach more than 500 billion yuan in 2015.

With the continuous improvement of LED white light luminous efficiency, the market share of LED functional lighting products is increasing gradually, and the growth rate is rapid. If the government from the perspective of energy saving and effective guidance and promotion, will quickly expand market share, and ultimately become the largest application areas and markets LED.
