See China LED war from 337 survey

Local 22, the U.S. International Trade Commission issued a notice, once again launched the "337 investigation". 13 Chinese LED lighting companies appear in the list of companies surveyed.

Shenzhen Jin Tian Lighting Technology Co., Ltd. deputy general manager Zhang Tieyong learned that the company has been included in the 337 investigation involved in the business, the first reaction was surprised. He had never heard of "337".

With the accident, the king of different fields, while being investigated several large companies for the 337 survey is not strange. As early as 2008, the United States on China's 4 LED lighting companies have launched an investigation of patent technology.

The United States has launched on the Chinese LED lighting enterprises patent infringement investigation, reflects the China short board in LED technology and heteronomy, also reflects the China LED industry very difficult road from the side of technology.

10 years behind the "technology" as people

In the early 90s of last century, after the study of the blue light LED in Japan, it quickly solved the white LED, making the LED lighting possible. After the advent of the rapid development of white LED, 10 years, luminous efficiency of white LED increased nearly 10 times, LED began as a new solid light source (SSL) to enter the lighting field, rising to Europe and the United States, a number of powerful LED lighting company.

10 years later in June 2003, the Ministry of science and technology and the Ministry of information industry, the Ministry of education, the Ministry of construction, the Chinese Academy of Sciences, light industry association and other units set up a national semiconductor lighting project coordination leading group, launched the national semiconductor lighting project, the same year the establishment of alliance national semiconductor lighting project. As a symbol, China's LED lighting industry started.

"Our LED lighting industry is 10 years behind the world. The late 90s of last century, Japan's LED lighting industry has been achieved industrialization. National semiconductor lighting engineering research and Industry Alliance Deputy Secretary General Nguyen told reporters.

Beijing semiconductor lighting technology promotion center of the Secretary General Geng Bo told reporters that although the LED lighting industry in China has made considerable progress, but in the current master the core technology is still not optimistic, the core intellectual property and intellectual property rights are in the hands of foreign manufacturers.

"From the current GaN based development of the LED industry in the world, the top 5 companies - the United States, Germany, Holland kerei OSRAM PHILPS, TOYOTA Japan Nichia has 80% ~ 90% and the synthesis of the original invention patent. Introduction of Geng Bo.

According to Ruan Jun introduction, at present, GaN based LED lighting products accounted for more than 80% of all LED products, and its core technology focused on the generation of GaN based epitaxial wafer. About the patent of this technology is more than 1000, basically in the hands of Japanese companies, our enterprises only a handful of edge technology patents. "

"Weak" LED industry big country

Although the country in the LED lighting industry related technology R & D investment continued to grow, but compared with the cost of R & D of foreign companies, or not enough.

Science and technology department in the 'fifteen' during the investment in the LED lighting industry was $50 million, '11th Five-Year' during the turn of 6 times to reach $300 million. And PHILPS is only one year for the 'solid-state lighting' (mainly for LED lighting) research investment of up to 40 million euros. Geng Bo said.

According to the latest industry data show that in 2011 the full year, China's LED lighting industry output value of about 150 billion yuan. From the output value, said the country entered the LED production. But Geng Bo believes that although China's production capacity is very large, but in the global industry chain LED lighting does not dominate. Is a big country, but not a powerful country.

LED chip is mainly dependent on imports, the use of domestic chip is very small, high power (1W and above) chip is not, the chip lacks its own technology and intellectual property rights. China has a large scale LED packaging industry, has a better equipment, but the packaging technology, materials and processes, there is still a gap. China Lighting Association, Specialized Committee, honorary director of interior lighting Ren Yuan told reporters.
