Research and Implementation on Methods of Evaluating Lifetime of LED Light Source for LED Lighting System

Rong Wang, Hai Bo Ma, Bin Qu

Abstract

This research adopts comprehensive evaluation to evaluate lifetime of LED light source for lighting system. By the method, under the condition of LED light source working outside, the situations of LED light source lifetime are analyzed with attenuation rate of illumination got from illumination data of LED light source in practical work. The real lifetime characteristics and real life curve of the LED light source are obtained eventually.
