Ruifeng Optoelectronics "thermally coupled white LED package optimization technology" breaks foreign barriers

"This is a scientific and technological achievement with completely independent intellectual property rights, which not only breaks the technical barriers of foreign countries, but also is in a leading position." Recently, Shenzhen Ruifeng Optoelectronics Co., Ltd. vice president and CTO Xiao Xiaoming said in an interview with this reporter that its The team led by the "multi-interface light-thermal coupling white LED package optimization technology" invention won the second prize of the 2016 National Technology Invention Award.

"Multi-interface light-thermal coupling white LED package optimization technology" is the product of the integration of market demand integration and production, education and research. Yan Xiaoming said that Ruifeng Optoelectronics relies on Shenzhen Science and Technology Resources, and combines Huazhong University of Science and Technology, Wuhan University and Guangdong Zhaoxin Enterprise to effectively combine various industrial factors such as industrial technology needs, enterprise existing technology platforms and university resources to promote technological innovation. , jointly invented the "multi-interface light-thermal coupling white LED package optimization technology." “Ruifeng Optoelectronics has made significant contributions to the input and output of results, that is, from scratch and the application of results.”

In fact, the “high-quality white LED optimization method and process” developed by the team is the first to be clarified internationally: the temperature of the fluorescent coating layer is another important factor affecting the quality of the LED package, and the color uniformity of the high-quality white LED space is established. The evaluation criteria, invented the LED package phosphor coating control technology; "Extended surface light source - light control composite lens" invented the extended surface light source energy mapping lens surface structure optimization method, breaking through the LED dependent free-form surface secondary lens optics Limitations of design; "Multiple high-efficiency light extraction and accurate light control LED composite lens structure" built a multi-interface-multiple heat source system LED diffusion thermal resistance network model, invented nanoporous copper thermocompression bonding technology, developed low temperature Bonded ceramic substrate (LTBC) preparation technology has broken the technical barriers of foreign countries and realized the export of products to the EU.

Yan Xiaoming revealed that the award-winning project is the result of 10 years of research and development of its R&D team: a total of 33 invention patents and 46 utility model patents, covering the mechanism model and scientific issues of electromechanical color heat and reliability related to LED packaging. The systematic research results of key materials, process methods, manufacturing technology and terminal applications are mostly basic original innovations, which will have a profound and far-reaching impact on packaging technology, especially for high-end LED packaging.
