| Abstract: | High-power LED （Light Emitting Diode） as a new generation of light, due to their high light conversion efficiency, low power consumption, environment friendship and long life, has been widely used in indoor and exterior lighting. The energy consumption for road lighting accounts for about 20% -30%. The LED used in road lighting has great economic value and market potential. High-power white LED is a semiconductor lighting device and is increasingly improving it＇s light efficiency and reducing it＇s costs, while increasing it＇s reliability is also highly required. In this paper proposed some ideas for the improvement of thermal dissipation and reliability. |
