Luminescent material model of AC LED products

LED lighting is another revolution following the incandescent lamp, fluorescent lamp lighting, efficient lighting to be recognized as the world's most promising industries.

By the Research Institute of Applied Chemistry Changchun China (hereinafter referred to as the Changchun Research Institute) afterglow luminescent materials of rare earth LED controllable life completed in cooperation with the Sichuan Limited by Share Ltd Sony light "and its application in semiconductor lighting in the results, the day before Jilin won the technical invention award.

"LED lighting source using existing DC as a driver, must be converted by AC and DC power at work, high energy consumption, poor heat dissipation and high cost." Research Fellow at the Institute of Applied Chemistry Changchun Chinese Li Chengyu told the "Chinese Science News" reporter: "the development of new lighting products can be directly used LED AC drive is the benefit of the people, great demand to promote the development of LED lighting industry."

For the LED directly is AC driven when the luminous stroboscopic problems of the world, Research Institute of the Sichuan Changchun Sony light limited cooperation in 2008 launched a new type of AC LED lighting technology.

After more than 6 years of unremitting exploration and development, the team developed a luminescent material as the core of the new communication technology LED. According to Li Chengyu introduction, the technology has reached the international advanced level, so that China has become the world's only able to use light emitting material production frequency flicker AC LED products in the country, promoted the exchange of China LED, especially in scientific research and industry development level of rare earth luminescent materials LED.

At present, the project has successfully in Sichuan Sony light Limited by Share Ltd and Limited by Share Ltd (Changchun), photoelectric transformation, the formation of the four major categories of products, lamps downlight, lights, spotlights, and successfully applied to the family, subway, shopping malls, hospitals and other areas.

Li Chengyu introduced the technology of simple circuit and low cost, good heat dissipation, high efficiency, long service life, service life can be improved more than 1 times, energy consumption and cost were reduced by 15% and 20%. At present, the products have passed the relevant certification in China, and the United States, European unity Underwriters Laboratory Certification, and exported to the United States, Canada, Mexico, Spain, Brazil and other countries, has achieved remarkable economic benefits.

It is reported that the results of the project has selected "2013 China rare earth science and Technology Press, ten, won the 2012 British Institute of engineering and Technology (IET)" energy innovation "and" building "two nomination award, 2013 annual" golden kangaroo "World Innovation Award, has obtained 4 Chinese invention patent authorization, PCT (3 the patent cooperation agreement) international patent applications in a number of countries have entered the trial stage.
