LED lighting is the second incandescent, fluorescent light source after another revolution, the world is recognized as the most promising high-performance lighting industry.
By the Chinese Academy of Sciences, Changchun Institute of Applied Chemistry (hereinafter referred to as Changchun should be) and Sichuan Xinli Light Source Co., Ltd. to complete the "afterglow lifetime controllable rare earth LED light-emitting materials research and development in semiconductor lighting applications," the results, Jilin Province Technology Invention Award first prize.
"The existing LED lighting source using DC as a driver, at work must be AC and DC power conversion, energy consumption, poor heat dissipation, high cost." Changchun Institute of Applied Chemistry researcher Li Chengyu told reporters: "Development can be directly The use of AC - driven new LED lighting products is to benefit the people, promote the development of LED lighting industry a major demand. pcm-5820-g0b2
In response to the world-wide problem of LED flashing directly by AC drive, Changchun should cooperate with Sichuan Xinli Light Source Co., Ltd. in 2008 to develop new AC LED lighting technology.
After more than 6 years of unremitting exploration and development, the team developed a kind of luminescent materials as the core of the new exchange of LED technology. According to Li Chengyu, the technology has reached the international advanced level, making China the world's only use of light-emitting materials to produce low-frequency flash LED products, a strong impetus to China's exchange of LED, especially rare earth exchange LED light-emitting materials research and industrial development .
At present, the project results have been successfully converted into four categories of products: bubble lamps, downlights, tube lights and spotlights in Sichuan Xinli Light Source Co., Ltd. and Zhongke Optoelectronics (Changchun) Co., Ltd., and successfully applied in home, Subway, shopping malls, hospitals and other fields.
Li Chengyu introduction, the technology products, simple circuit, low cost, good heat dissipation, high energy efficiency, long life, can improve the life of more than 1 times, energy consumption and cost reduction of 15% and 20%. At present, the products have passed the relevant certification in China, and the United States Underwriters Laboratories, the European unity certification, and sold to the United States, Canada, Mexico, Spain, Brazil and other countries, achieved significant economic benefits. xc3s200-4tqg144c
It is reported that the project results have been selected "2013 China Rare Earth Ten Science and Technology News", won the 2012 British Institute of Engineering (IET) "energy innovation" and "building environment" two nominations, 2013 "Golden Kangaroo" Has won four patents for invention in China, and three international patent applications for PCT (Patent Cooperation Agreement) have entered the stage of trial in many countries.
