Gao Jiwei: COB LED packaged into LED general lighting mainstream technology solution
Technology is the main driving force behind the industry's development, especially for the emerging LED industry. On the afternoon of December 15th, the 2012 Hi-Tech LED Conference Technology Specialized by Shanxi Guangyu Lighting--the latest technology of LED industry chain was held in Shenzhen Guanlan Lake (Dongguan Club) International Conference Center. The experts and technical leaders of the conference attended the LED. The industry's recent technological development and other issues are being discussed.
Participants highlighted the current state of the art in the LED industry, including phosphors, LED drivers, innovative COB light source technology, new SMD LED packaging and new test technologies, and future design trends for LED lighting. The leaders of many LED companies participating in the conference answered the questions about the new LED technology.
Dr. Gao Jiwei, Technical Director of Hangke Optoelectronics, said that with the development of LED applications, there are many requirements for packaging. COB LED packaging technology is the mainstream technical solution for LED general lighting that is recognized by domestic and foreign industry. COB packages have many advantages in terms of heat dissipation, overall illumination, and cost. The key to the future development of COB depends on the market, and it needs to continue to mature in technology and technology, while reducing costs and improving cost performance.
