Development of high-power LED enterprises mainly at home and abroad

Up to 2010, there are more than one hundred manufacturers of power LEDs for lighting production in China, and the quality of high-power LEDs produced by them are also different. Domestically, Guoxing Optoelectronics, Jiuzhou Optoelectronics, Ruifeng Optoelectronics, Quantum Optoelectronics, Shanxi LEDs for lighting produced by Guangyu, Zhongzhou Optoelectronics and other manufacturers represent a higher level of domestic devices. According to the statistics of relevant research institutions, Guoxing Optoelectronics, Jiuzhou Optoelectronics and Ruifeng Photoelectricity ranked the top three in the LED lighting market in 2009, among which Ruifeng Optoelectronics ranked first in the Shenzhen market. Guoxing Optoelectronics pioneered the international high-power LED device structure based on PCB, and achieved innovation in substrate materials and production processes.

At the end of 2009, Guoxing Optoelectronics set up the LED lighting division and began to engage in research and development and production of LED application products such as LED lamps and light source modules, and officially entered the downstream of the industry. As a subsidiary of Sichuan Jiuzhou Electric Group, Jiuzhou Optoelectronics entered the packaging industry in 2004. In 2007, it expanded its high-power lighting business through mergers and acquisitions, including 100lm/W high-power LED development, LED streetlight core technology and railcars. And research and industrialization of LED lighting products for ships. At present, more than 90 patents including invention patents have been applied. Ruifeng Optoelectronics is the only company among the top three domestic companies to focus on LED device packaging. It focuses on core technology research and development, and establishes technical cooperation with many universities and colleges in the Mainland and Konka Group in eutectic technology, secondary optics and high. The development of thermal conductive materials, surface roughening technology (currently can increase the light output efficiency of the overall product by more than 30%), the color rendering index of the product (currently up to 95 or more, which far exceeds the specified 80 standard), no light Point surface light source, silica gel molding, ceramic product development and other technical aspects are leading domestic level.

Ruifeng Optoelectronics has become a mainstream supplier of optoelectronic devices in the fields of automotive instrumentation, car audio, car DVD, medium and large size LCD backlight, mobile phone, indoor lighting and decorative lighting. The LED output of these manufacturers occupies more than 60% of the domestic market, and the average gross profit margin of the products is around 30%. At present, these domestic enterprises can be compared with the world's first-tier manufacturers in terms of packaging technology. Therefore, compared with imported devices, domestic packaged lighting power LED devices have great comparative advantages, and the price is also in line with Taiwan products.

At present, foreign manufacturers mainly represent Cree and Philips Lumileds, which represent the highest quality high-power LEDs on the market, and basically occupy more than 90% of the global high-power LED high-end market. Due to the wide variety of Cree products, high-power LEDs of various specifications are relatively complete, and the output is large and the supply is stable, which becomes the mainstream of high-power LEDs. The high-power LEDs produced in Taiwan account for the majority of the mid-end market, and the high-power LEDs produced by them are cost-effective.
