| Abstract: | This paper puts forward an evaluation method for LED component＇s quality. The lighting conversion efficiency and the maintain rate of radiant intensity will be lead into the key parameters of the LED component＇s quality. The chip size and the current density will be used to regulate the LED component＇s quality. In order to eliminate the early failure component, It gives the the screening method. In the end,this paper introduces the endurance test which is related to LED component＇s reliability. |
