Today, China has become the world's most important production base for low-end led package, expected in 2010 China's LED industry will reach 1,000 billion yuan.
However, the current multi-core technology of LED lighting industry for foreign controlled enterprises. Mainly concentrated in the upper reaches of the core patent of Nichia Chemical (Japan), Osram (Germany), Christian (USA), General Electric (USA), Toyoda Gosei (Japan) and Samsung (Korea) and other large companies in the hands, from the United States, Japanese and European companies have occupied most of the market share, and LED lighting industry chain with 85% -90% of area original patent.
According to the Guangdong Provincial Intellectual Property Bureau and the Guangdong Provincial Information Industry jointly issued the "LED industry patent trend analysis report"shows: the related patent applications in the LED States, Japan, the world champion clocked 27.9% of the patent, while China accounted for only 9.34% . related survey, the package is our main area of research and development and application of patent applications accounted for 39% of total, followed by the application of technology, epitaxy, chip technology, white technology and substrate technology, LED related patents mainly involve the preparation Methods and equipment.
LED-related patents in 2009
United States, Japan and Europe: LED business about 20, more than 300,000 patent applications, accounting for 85% -90%.
China: about 62 chip companies, about 30,000 patents, less than 10%.
Developed countries to promote the process of semiconductor lighting
United States: From 2006 to 2011, arranged $ 50,000,000 per year for the semiconductor lighting program (NGLI) technology research and development. In 2010, the United States will have 55% of incandescent and fluorescent lights were replaced by semiconductor, saving 35 billion U.S. dollars per year.
Japan: in 2003, semiconductor lighting program started the second period. In 2010 the luminous efficiency white LED 120lm / w, 2020, 50% want to replace all incandescent and fluorescent lamps.
Europe: 2020 using the LED luminous efficiency of 200lm / w, the energy consumption by 20%.
