◆ obtain approval of well-known experts, LED light source package and application technology to the international and domestic leading level
(Reporter On Lan Singapore) Ltd., Dongguan Kingsun lighting in the semiconductor chip (LED) packages with non-imaging optical processing technology, the second major breakthrough, the use of new technology to produce the LED lights 20 in Dongguan Town road traffic trunk and a large-scale alternative to the standard high pressure sodium lamps. LED lights have been installed tens of thousands of domestic lights, road length over 400 km, the longest setup time more than one and a half. Light power by the State Quality Supervision and Inspection Center, Ministry of Information Industry Institute of Electronics and other authorities Fifth finds that the main technical indicators have reached international leading level.
"Diligence on the" street of large-scale application, which marks the entry of functional LED lighting commercial lighting stage of industrial packaging and application of LED technology has matured and development will have a positive role in promoting, has important social significance and economic significance.
Established in 1993, Dongguan Kingsun Optoelectronic Co., Ltd., is a high-tech enterprises in Guangdong Province, Tsinghua University, the field of semiconductor lighting partner, China's semiconductor lighting technology standards working group members, Chairman of Guangdong Provincial LED Industry Alliance units, the registered capital of 110 million yuan, has more than 2,000 employees, more than 400 engineering and technical personnel. In 1998, the ground began LED decorative lighting on the development and application; in the city in 2002 the extensive use of LED lighting project light, LED light source applications while the Christmas tree, light painting, electric deer, decorative lights, Christmas decorations product areas , selling products in international markets. 2004, 2004, the ground began to research and development of high power LED applications, development of a new generation of LED light sources to be used in functional lighting.
Sense of innovation and research cooperation is "on the ground," the driving force and magic breakthrough. Career their companies and the United States, on the single 1 watt LED package using a special technology package structure and eutectic solder line to tackle the problems of new technology has been successful, the new technology to reduce the thermal resistance, improved thermal efficiency and luminous efficiency, main optical parameters to achieve a new level, the measured decline of 5,000 small-time less than 1%, the luminous efficiency of 100 lm / W, color rendering index Ra of 75 or more, and comprehensively improve the LED as the light source level.
In early 2007, with Tsinghua University on the ground "production, learning and research" cooperation, according to non-imaging optics to develop a unique secondary optical processing devices, and tackled the problem of uniform light distribution, and thermal design system, the circuit driving systems, remote wireless intelligent control systems to achieve technological innovation and application of new technology development, its energy-saving LED street lamps, illumination, uniformity, safety, water, dust and other indicators fully meet the state standards for road lighting, the Ministry of Information Industry Electronics Research Institute and other authorities five tests, the technical indicators have reached the national highway safety standards used, the average illumination of 0.6 or more, exceeding the national level, the provisions of road lighting standard 0.4, the optimized efficiency of 94% of the switching power supply , system life is more than 5 million hours. November 2007, undertaken in the ground on the science and technology projects in Guangdong Province, "High-power LED street lamp," scientific and technological achievements appraisal meeting, Kingsun research was identified as the main index reached domestic leading level; February 2008, developed on the ground LED lights are included in the national key new products, and was included in the national 863 project.
After several years of hardships, the development in the LED industry, the total investment 300 million yuan, have the LED light source package technology and processes, development of automated production equipment, thermal efficiency and luminous efficiency and achieved a breakthrough series, successfully resolved the LED heat, constant current source driver, lighting design and many other problems, mass production capability, LED light source step into the field of functional lighting. Has developed outdoor lighting street lighting, wind and solar LED lights, tunnel lights, floodlights, parking lights, explosion-proof lights, port pole lamp and other products; indoor lighting grid lamps, cabinet lamps, wall lamps, ceiling lights, etc. products; city lighting spotlights, garden lights, buried lights, rainbow lamp, and other three series of products, has completed more than 200 cases of lighting projects.
According to reports, so far, has Kingsun invention and utility model patents at home and abroad more than 100 to fill a number of gaps, the formation of independent intellectual property rights system, with full reference to the U.S. UL standard configuration of the laboratory; to Tsinghua University University, State Key Laboratory on Integrated Optoelectronics, led, the combination of leading domestic semiconductor lighting senior scientific research personnel, including 17 doctoral and post-doctoral, Master 48. China's semiconductor lighting standards as members of the Working Group, Guangdong Province, the first President of the Union units LED industry, diligence on the participants in a national LED road lighting standards, Guangdong Province, LED street lamp standards, national standards and local standards for a number of development work.
Kingsun has a strong research and development and advanced automated production system. In recent years, have set up a semiconductor lighting technology and application Research Institute, Guangdong Province, semiconductor lighting technology and application engineering center, technology center in Guangdong Province, LED packaging factory, lighting plant, factory complete LED lighting chain, has built 20 million square meters of production base for semiconductor lighting, with Asia's largest and most advanced full automatic production system, became the modular high-power LED light source, the scale of large-scale production of LED semiconductor illumination lamp enterprises, in order to meet functional commercial lighting market come ready.
Solid State Lighting R & D and industry, League Secretary General, National Semiconductor Lighting Project Coordination Leading Group Office of the Vice-Miss Ren Wuling, China Lighting Association chairman Chen Yansheng, Zhang Hai Cong renowned lighting experts, Wengyin Fu, Ren Yuan Council, the leadership of Guangdong authorities has come to Changping, Shilong Town, Shek Pai town, street and site visits, were given a higher rating.
Kingsun Chairman Li Xuliang confident that rely on innovation awareness and research cooperation, completed the ground from the outdoor lighting to LED lighting industry, from manufacturing to create, from traditional industries to high-tech industry structural changes, into the new stage of development. We must resolutely along with LED lighting, LED decorative light, wind, solar and LED lighting industry as the core of the combination of development along this road, China's semiconductor lighting industry as the largest contribution to the development.
