Wu Ling: dialectical view of the development of China's semiconductor lighting industry

"2008 Green Lighting Forum" was held in Beijing on November 8th. National semiconductor lighting engineering research and development and Industry Alliance Secretary General Wu Ling attended and made the China semiconductor lighting industry development prospects and outlook, the theme of the report.

In the report of the Secretary General Wu first introduced the development status of semiconductor lighting industry in China and pointed out that the extension of the upstream industry chain is the growth of semiconductor lighting industry, the highest technical content of the final product quality, cost control of the largest part of. The MOCVD system is the main equipment of GaN based LED epitaxial growth, accounting for the cost of a 40-50% extension, but more than 90% of the global market is monopolized by the German AIXTRON and American VEECO companies; the raw materials of semiconductor lighting industry to MO source, sapphire substrate, SiC substrate and NH3 gas, but also by the United States, Europe, Japan and other countries to control at present. Therefore, the key technology and important equipment is a bottleneck in the development of China's semiconductor lighting industry. In the midstream, Secretary General Wu said, now the power type chip light efficiency increased by 26% per year, the annual price fell 50%; from the initial structure of the chip structure suits to the flip structure, vertical structure, chip integration and other forms of common development, the luminous efficiency is from 20 lm/W in 2003 to 2007 80 lm/W; at higher concentration of the industry sectors, mainly in the United States, Japan, China Taiwan and other places, but in the recent 5 years the domestic development speed very quickly, before 2002 the domestic blue chip all rely on imports, until the end of 2007, the localization rate has reached 35%.

On the application of LED, the Secretary General Wu believes that now the new applications and emerging market opportunities for general lighting industry leading large, special lighting products have been mature, the market is from the display to the lighting, special lighting to change from the general lighting application field in our country; the domestic patent number, growth, emergence close cooperation, interdisciplinary field, industry good situation; application of product type and the scale of our country at the international forefront, has become a global full-color LED display, solar LED landscape lighting application products the largest production and export country.

Secretary General Wu Ling introduces not only the steady growth of the landscape lighting, small and medium size backlight lighting, display, special lighting, automotive lighting applications market situation, but also on the LCD TV backlight module lamp rapidly and large size growth in recent years is forecasted. Pointed out that the mainland street lamp reached 800 million yuan in 2008, will reach $5 billion in 2010. According to each street lamp 100 1W high-power LED estimates, only the mainland market in 2010 the demand for high-power LED chip to reach 150 million. LED backlight notebook computer to permeability in 2010 will reach 45%, an increase of 7 times the size of the market, from $130 million in 2007 increased to $950 million; by 2010, if there is a LED backlight module with 50 million LCD TVs, high brightness LED demand will reach 9 billion, 3 times the current global production capacity.

Wu Ling in the report also introduces the regional development situation, China's semiconductor lighting industry investment status and technical development, and said that the 863 projects of the field of semiconductor lighting good start, overall progress smoothly, part of the project completed the stage goal ahead, some key technology has made a breakthrough.

In the analysis of the future development of the situation, Wu Ling believes that China's semiconductor lighting industry both opportunities and challenges. In energy saving and environmental protection under the background of government support and the huge market demand is a rare historical opportunity; China's rich raw material resources and industrial base, has formed a good environment for international exchanges and cooperation have provided favorable conditions for the development of semiconductor lighting industry. At the same time should also be soberly aware that, from the research and development level to the enterprise level, and then to the industrial environment there are a series of huge challenges need to deal with. One end of the industrial chain (ie equipment and raw materials) one end (that is, high-end application products) has become a key link in the development of China's industry. In addition, the enterprise scale, product grade, testing standards, policies and other aspects of the industry also need to work together to continue to improve and improve.

On the future direction of development, Wu Ling said the Secretary General to form a new industry with independent intellectual property rights and international competitiveness! "Specifically is to break through the white general lighting core technology, independent innovation; key technology to solve the urgent need of the market industry, the development of supporting industries; establish and perfect the technology innovation system and industrial clusters, improve the industrial chain.

At the end of the report, the Secretary General Wu said hopefully, semiconductor lighting is not only a revolutionary technology, but also is a global industry, for our country should be the strategic industry, the future direction of visible eyes done into the!
