Response to the “patent war”. 2010 there will be some of the important field of white LED patent expires, other words, LED industry in recent years into a frequent patent litigation battle. According to incomplete statistics, the global LED household lighting application 124,000, which the United States, 20000 China, 25000, 49000 Japan accounted for. The key is the 25000 LED patent in China, mostly concentrated in the middle and lower reaches of the whole industrial chain, mostly design, utility model patents, invention patent very little. All have some peripheral patent in the upstream industry chain, but the core patents master degree.
Balance productivity growth and market demand. According to incomplete statistics, in 2010 only listed company in the investment in the field of LED over 30 billion yuan, 20 billion yuan of three safety photoelectric BDO Runda 4 billion yuan. LED industry investment in 2010, about 37% to invest in the upstream chip areas, 52% to invest in downstream applications, signs of overcapacity initially appeared. 1 July 2011, China MOCVD equipment increased by more than 200 units, is expected in 2012, China LED household lighting chip production capacity is 10 times that of 2010. MOCVD equipment in China more than 500 units, count 96 projects under construction, the total number of over 1600. According to statistics, the sapphire substrate manufacturing enterprises 41, planning a total investment of 44.7 billion yuan, including the planning of projects under construction amounted to 12.08 billion yuan in the projects under construction production capacity of 101 million / year. However, due to the global economic situation is not optimistic, the LED high bay chip demand declining. How to expand the LED general lighting market, and how the government should support the market, how to cultivate, all we need to solve.
