【China Building Materials Network] Heat dissipation of LED: when the brightness of LED is increased, the temperature of LED increases rapidly. Therefore, how to solve this heat dissipation problem has become a technical problem to improve LED brightness. The optical design of LED lighting lamps, how to carry out optical design when using LED to design lighting equipment, does not affect the lighting effect. 1. High-power LED secondary optical light distribution 2. High-power LED heat dissipation system 3. LED phosphor surface coating
