Mainland LED chip share is not high, still need to work hard

Chinese according to national semiconductor lighting engineering research and Industry Association statistics, in 2008 China's LED chip output growth of 26%, up to 1 billion 900 million yuan RMB. However, since most of China's LED chip companies do not have a complete intellectual property system, especially in the application of a wide range of high-power lighting LED market, China's share of the chip is not high.

Main production of high-power LED lamp Dongguan cled digital photoelectric technology Co Ltd said the reason. Assistant General Manager of the company, Zhu said: "in general, we only use imported brands of chips. Of course, there will be some time according to the requirements of the owners choose the mainland LED chip. Due to the vast majority of continental power LED chip can not meet the needs of customers, and even can not be detected by our own. Therefore, we are not willing to use domestic chip. "

The mainstream technology of the global market LED chip substrate is manufacturing sapphire substrate technology and silicon carbide substrate technology, they belong to Japan Nichia Corporation and the American CREE company. Sapphire technology, chip manufacturing enterprises mostly use Nichia, but need to pay a lot of money in Japan Nichia patent fees. However, Jiangxi crystal photoelectric Co., Ltd. is breaking the monopoly. At present, latticepower with silicon substrate Gan LED technology, executive vice president Wang Min pointed out: "the silicon substrate LED chip has many benefits, with original intellectual property, not restricted by international patents in the international market; good antistatic performance and long service life; the silicon substrate LED chip on the lower electrode, single lead vertical structure reduce the packaging cost. In addition to the above benefits, the most direct advantage of silicon substrate technology is the cost. Latticepower a staff pointed out that "the biggest advantage compared to sapphire and silicon carbide on silicon substrate is the cost, the cost is very low, coupled with the production process of some advantages, LED chip costs far less than the sapphire and silicon carbide substrate. "Although the technology leader, but the results of the laboratory and the factory products are still different. It is understood that the current crystal photovoltaic power lighting chip yield is still not high. A staff member latticepower shares Jiangxi latticelighting Co. Ltd., said: "we have high power lighting products to buy a part of the American Cree company, because the yield rate is not latticepower. "

Early in 2006, began latticepower silicon substrate LED chip industrialization attempt, but not until May 2008 was the LED chip production. Currently, the crystal energy LED chip production capacity has been close to 10 billion, the overall yield of about 80%. The crystal energy photoelectric staff said: we will enter the LED chip packaging area before the end of the year, extending downstream. "

At present, falling prices for upstream equipment makes the application of LED LED chip manufacturing industry and downstream gained more profit space. Although most of the mainland LED companies do not have the core technology, but because of the rapid expansion of the market, the future of the LED industry will continue to maintain a certain business cycle.
