Jiuzhou optoelectronics as a subsidiary of Sichuan Jiuzhou Electric group, in 2004 into the packaging industry, 2007 high power lighting business was expanding promotional gifts through acquisitions, including the core technology of high power LED 100lm/W Research and development, LED street lamps and LED lighting products for rail cars and ships research and industrialization.
Already, including the patent for invention patent applications over more than 90. Swiss Feng photoelectric is is domestic Qian three name enterprise in the only focused lighting with LED devices package of enterprise, focusing on core technology research and development, and Mainland more by University homes by and the KONKA group established technology cooperation, in total Crystal technology, and II times optical, and high thermal conductivity material of development, and surface rough of technology (currently can upgrade overall products of out light efficiency 30% above), and products of explicit color index (currently highest can do 95 above, this far over by provides of 80 of standard), and no light points surface light source, and silicone molding, and Ceramic product development technologies, such as the domestic leading level. Rui Feng photoelectric has become the world's automobile instrument, car audio, car DVD, the large size LCD backlight for indoor lighting, decorative lighting, cell phones, and other leading vendors of optoelectronic devices in the field. These manufacturers of lighting LED production up over 60% of the domestic market, products the average gross profit margin was about 30%.
At present the domestic enterprises on the packaging technology can be used with first-tier manufacturers in the world match, so compared to imported devices, lighting in the domestic package with power LED device has a comparative advantage, price and also Taiwan product line.
Representatives of foreign manufacturers currently mainly Cree and LumiLEDs high power LED with the highest quality on the market, basically getting a high power LED 90% for high-end markets in the world over. Cree given the large variety of products, all kinds of high-power LED more complete, more stable production and supply of high power LED the mainstream. China Taiwan high power LED production accounted for most of the mid-tier market, and its production of high-power LED high cost performance.
Analysis on characteristics and development trend of high power LED
Development of high power LED lighting applications primarily targets, despite general agreement that LED into the General lighting sector is still a certain threshold, but with the miner's lamp and landscape lighting, LCD backlight applications, rapid development of functional lighting applications such as street lamps, high-power white LED light is still in the specification and application of improving the scale of the expansion has maintained a very fast pace of development, is expected in the next few years for high power LED's growth rate is expected to remain at more than 50%.
Under United States Holy Land Asia national laboratory by do of LED lighting cost analysis, investment cost is will a bulb of purchased cost (each trillion lumens) sharing to entire life cycle, run cost is means a bulb in run Shi of cost (each trillion lumens Shi), has cost is investment cost and run cost of and, reflect has a bulb from purchased, and run to what entire life cycle of total cost. LED lighting technology development goals are: increasing 25lm/W of luminous efficiency in stages from 2002 to 2007 75lm/W 200lm/W of 150lm/W, 2010 and 2020, the light will cost from $ 200 in 2002/reduced in 2007 to $ 20 per thousand thousand lumens lumens, 2010 $ 5 per thousand lumen in 2020 and $ 2 per thousand lumen. With the extensions of application areas and markets, characteristics and development trend of high power LED is also gradually undergoing some changes, show some new features:
1, mainstream LED pricing to reduce
Currently, Cree production of luminous flux 70~90LM of 1W white light LED products market price basic maintained in 17 Yuan around, with type of LumiLEDs products price in 19~21 Yuan around; China Taiwan 1W white light LED (luminous flux 70~80lm) price from 10 Yuan to 15 Yuan ranged; mainland used imports chip package of high power LED price and Taiwan products par, domestic production of high power LED (50~60lm) price basic in 5.5 Yuan around.
Now has the capability to mass supplies white LED power device manufacturers are still located in Shui Feng photoelectric, country stars, Guangzhou hongli and Taiwan millions of manufacturers such as light, Lite, accompanied by a high power white LED applications growth and photosynthetic efficiency is on the rise, their single LED prices are expected to gradually reduce.
2, cost, and the heat sink is still LED the biggest obstacle to replacing traditional lighting
Lighting is the most attractive LED application areas, costs LED to replace the traditional lighting is critical. Although LED's price relative to its exponentially from the traditional life of the lamp is not high, and can save late use of replacement and maintenance costs, but the starting fees are directly subject to purchase budget. Philips that affect current LED applications the main bottleneck is that lumen cost 10 times higher than traditional lighting source. Therefore efficiency to 150 optical lm/W, current from 700 mA up to 2 a, while core and packaging costs should be reduced by half, in order to use weapons in lighting.
Ministry Deputy Inspector Guan Baiyu said electronic information Division, LED packaged is a device integrated with light and heat and fever LED devices have maximum effect, if the total lighting under conditions of high temperature, it will greatly influence the life of lighting devices or lighting, so the package structure to LED lights posed a severe challenge.
3, high power LED broad market prospects for domestic use
At present, landscape lighting market is the largest application of high-power LED lighting market, the share of about 43%. It's a new round of rapid growth is bound to bring new impetus to the development of high-power LED lighting industry as a whole. In addition, through the world's leading manufacturer of high power LED technology on positive improvements in materials, processing and packaging technology, high-power LED luminous efficiency and enhance performance, high power LED has begun towards the indoor and outdoor general lighting, automotive lighting, searchlights and other new markets both inside and outside. High-power LED lighting industry will achieve leaping development in the next 3-5, subversion of the traditional lighting industry.
