The leading enterprises of domestic LED

Wei Shiman investment advisory firm King Xingyu executive director, said the industry's most leading Japanese technology companies strict blockade, in which pairs of GaN material research of the most successful Japanese Nichia and Toyoda Gosei of MOCVD equipment, no foreign sales, another more mature technology, Nippon Sanso company's equipment is limited to sale in Japan. Belong to the same chip manufacturing technology and capital-intensive industries, entry barriers are still high. The current core technologies also rests in the hands of large companies, such as the United States HP, Cree, German Osram, etc.. These companies rely on patents to build barriers to entry and patent litigation to prevent other manufacturers enter the market to compete with a monopoly of access to the high interests of the patent and formed a strong alliance.

Currently 3 LED's leading enterprises that can produce an optical luminous efficiency of 80lm / W level, while the international indicator is the luminous efficiency of 100lm / W, used as criteria for an optical three-level and international level is still a difference of 2 to 3 years about. In epitaxial films, large chips in these two areas, the domestic manufacturers and foreign giants so far apart, the domestic short-term is difficult to catch up, even if the catch is also not open around the patent issues.

A direct result of the gap between the technical aspects of LED lighting products of varying quality. According to industry research organization, LEDinside statistics, in the implementation of the "City 10000 10" program in 21 cities, only Weifang, Chongqing, Baoding explicitly put forward the three cities, the amount of LED lights to be installed more than 10,000, mainly because China is still the standard lamp is not baked, and the quality of LED lights has yet to be time-tested. In early 2009, the market is expected to have 800000-1200000 LED lamps demand, but the end of 2009, the installation volume of less than 300,000, while those who do "experimental" city, LED lights do not effect the promotion of satisfactory.

BDO Runda Deputy General Dunfee also "Red Weekly" said, LED lighting to achieve the civilian, in the heat, light and so bad that there are many technical problems to be resolved. Therefore, whether it is an optical or three BDO Runda, in the LED industry input on a lot of money, how to solve the LED chip technology issues are the key to their success.
