The '3rd Japan LED and Organic EL Lighting Exhibition' held at Ariake International Convention and Exhibition Center in Tokyo on January 16-18, 2013 China Premium LED Wall Pack Light On the previous day, Tamura Manufacturing Co. After several years of research, the research team under the research group of Professor Kang Junyong of the School of Physics and Mechanical and Electrical Engineering of Xiamen University, the research team\u2019s associate professor Huang Kai and PhD student Gao Na borrowed an ultra-thin aluminum film to solve this problem.The research team of Xiamen University has covered a layer of ultra-thin aluminum film on the surface of high-aluminum nitride deep-ultraviolet light-emitting diodes, cracking the restrictions on the wider application of this light-emitting device 'Light extraction efficiency' The key problem opens up new methods and ideas for the industrial application of such devices in the medical, environmental, military and other fields in the future. exhibited its developed white LED using gallium oxide Ga2O3. This invention alone has already applied for 18 national patents and utility model patents. Tamura Manufacturing Co. Under the global energy crisis, the domestic phasing out of incandescent lamps was put on the agenda in October 2012. Its surface is covered with a conductive circuit board, and a certain number of LED lights are evenly distributed, which can provide a wide range of Illuminate and increase brightness.
