Recently, 10 Chinese Academy of Sciences, 2 National Natural Science Foundation of China led by three industry experts and expert appraisal group, the Chinese Academy of Sciences Changchun Institute of Applied Chemistry and Chengdu High-tech Zone, Sichuan Xinli Light Source Co., Ltd. jointly developed " Luminescence persistence life controllable Rare Earth LED luminescent materials research and development and its application in semiconductor lighting "carried out the results of identification.
The accreditation team of the Chinese Academy of Sciences unanimously approved the appraisal and considered the project made a major breakthrough in the field of rare earth luminescent materials and the global semiconductor lighting technology. The original rare earth luminescent material effectively solves the stroboscopic AC LED lighting equipment that has been unable to break through in the world. It is reported that the achievement of the leap from basic research to industrialization has reached the international advanced level, making China the only country in the world to master the production of low frequency flash AC LED products through rare earth phosphors. The promotion of the use of technology will effectively extend the life of AC LED lighting equipment, and to better reduce the energy consumption of lighting equipment.
Reporters learned that the Chinese Academy of Sciences appraisal team of Sony and Changchun Institute of Optoelectronics should cooperate, independent research and development of a new generation of exchange LED lighting technology, will make "Chengdu made" LED lighting technology to the world's leading level, the technology used in the next five to Ten years will have hundreds of billions level and even one trillion level lighting new industry.
"We spent nearly 10 years, together with the Changchun Institute of Applied Chemistry, Chinese Academy of Sciences research, independent research and development of a new generation of AC LED lighting technology." According to Sony Lighting President Zhang Ming introduced most of the current global LED lighting manufacturers are Is a DC LED lighting device, but all of the DC LED lighting equipment to be configured with a AC to DC drive, the components of the drive life is much lower than the life of the LED, so the life of the DC LED is much shorter than the exchange LED, and a substantial increase in the cost of LED lighting equipment.
However, the global research and development exchange LED manufacturers have been unable to solve a bottleneck is the exchange of LED lighting stroboscopic problems, and the Chinese Academy of Sciences Changchun Institute of Applied Chemistry and Sony of the successful combination of rare earth long afterglow luminescence technology and semiconductor lighting technology, From a fundamental solution to the Philips, Osram and other international lighting giants can not solve the stroboscopic issues.
Reporters also learned that Sony's new generation of LED lighting source research and development than the average DC LED lighting equipment, energy-saving 15%, 50% energy saving than conventional energy-saving lamps, and only the traditional incandescent energy consumption 1 / 8-1 / 10. "For example, if the current use of all the general energy-saving lamps in Chengdu, then replaced by exchange of technical LED lighting, the existing power consumption can light up two Chengdu."
