Development of domestic and foreign main production of high power LED Enterprises

Development to 2010, Chinese production power LED lighting manufacturers have more than 100 LED, high power quality production are different, the higher level currently to nationstar, Jiuzhou optoelectronics, REFOND optoelectronics, Quantum Optoelectronics, Shanxi Guangyu, Zhongzhou photoelectric lighting with other manufacturers on behalf of the domestic LED devices. According to the relevant research institutions statistics show that the National Star optoelectronics, Jiuzhou optoelectronics, Ruifeng photoelectric 2009 lighting LED market share of the top three, which is the first in the Shenzhen market. China Star optoelectronics pioneered the international PCB based high-power LED device structure, in the substrate materials, production processes and other aspects of innovation.

Nationstar set up at the end of 2009, LED lighting division, began to engage in R & D and production of LED lamps, light source module and other LED applications, an official involved in the downstream industry. Jiuzhou optoelectronics as Sichuan Jiuzhou Electric Group subsidiary, in 2004 to enter the packaging industry, 2007 expansion of the high power lighting business by way of mergers and acquisitions, including LED lighting products research and industrialization of 100lm/W high power LED core technology and R & D, LED street light rail carriages and ships. Currently has applied for patents, including invention patents, including a total of more than 90. REFOND is the former LED device package enterprises with only three enterprises in the lighting, focus on the development of core technology, Konka Group set up technical cooperation with many universities in the mainland and, eutectic technology, two optical and high thermal conductivity materials development, surface roughening Technology (currently can enhance the overall the product above the light efficiency 30%) and the color index of the products (currently the highest can do more than 95, far more than the standard 80 required), no spot surface light source, silica gel molding, ceramic product development and technology leading domestic level.

REFOND optoelectronic devices has become a mainstream supplier global automotive instrumentation, car audio, car DVD, large size LCD backlight, mobile phone, indoor lighting, decorative lighting and other fields. These manufacturers with LED lighting production accounted for more than 60% of the domestic market, the average gross margin of about. At present, the domestic enterprises in the packaging technology with the first-line manufacturers par, so compared with imported devices, power LED devices have great advantages compared to domestic lighting package, the price is in line with the products of Taiwan.

Present foreign manufacturers mainly Cree and PhilipsLumileds represent the market the highest quality high power LED, basically accounted for more than LED high power global high-end market 90%. Due to the variety of Cree products, a variety of specifications of high power LED is relatively complete, large output and more stable supply has become the mainstream of high-power LED. While China's Taiwan production of high-power LED accounted for most of the middle market, the production of high power LED cost-effective.
