On the two main roads of Nanhai District, Foshan Nanhai Avenue and Haiba Road, there are tall street lamps that illuminate the road in every night. In Shanghai, 15,000 kilometers away, the first Yangtze River tunnel with LED tunnel lighting in China, built-in LED strip tunnel light, can not only stepless dimming, but also automatic detection of faults, automatic light fade detection, significant energy saving effect. The above street lamps are all manufactured by Zhaoxin. The realization of these scenarios is due to the breakthrough of multi-interface light-thermal coupling white LED package optimization technology. Anyone familiar with Zhaoxin knows that this is a local Foshan company with decades of history. Through repeated transformation and upgrading, it has become a modern enterprise group with the optoelectronics industry as its main body. Currently, it has four high-tech enterprises. In the view of Wan Xiaocheng, the director and deputy general manager of Guangdong Zhaoxin Group Co., Ltd., the group realized cross-border transformation, and the driving force came from the innovation rule in corporate culture. The magic weapon is the cooperation with the high-tech team. Breaking through the bottleneck of LED packaging technology and rapidly occupying the street lamp market In January this year, the 2016 National Science and Technology Award was announced. Guangdong Zhaoxin Group Co., Ltd., together with Huazhong University of Science and Technology and Shenzhen Ruifeng Optoelectronics Co., Ltd., jointly won the second prize of the National Technology Invention Award for multi-interface light-thermal coupling white LED package optimization technology. As a technology application company, the Zhaoxin Group is the lead promoter of this technology. Wan Xiaocheng introduced the research and development experience of this technology to reporters: Before 2008, due to technical limitations, the brightness of LED street lighting produced in China was difficult to reach 90 lumens/watt. This brightness parameter is important for LED lamps to be used for street lighting. Technical indicators. The streetlights on Nanhai Avenue are produced by Zhaoxin Group. The Zhaoxin LED streetlight intelligent lighting system has covered many roads in Guicheng. In this market gap, Zhaoxin Group began to plan cooperation with Liu Sheng team of Huazhong University of Science and Technology to try to break through the technical bottlenecks of a series of basic technologies, materials and processes involved in LED packaging in China, and fundamentally solve the optimization of high-quality white LED package. Method and process. In 2008, through the use of new production processes, the Zhaoxin Group produced street lights with a brightness of 90 lumens per watt and successfully applied it on multiple roads in Foshan. After several years of improvement, the street lamps produced by Zhaoxin can now reach 150 lumens/watt, and even reach 180 lumens/watt in the laboratory. At present, the above research and development results have been successfully applied in the development of products such as LED road lighting and commercial lighting of Zhaoxin Group, and obtained 12 relevant invention patents, which provided strong support for the company's product technology innovation.
