Abstract：

An　efficient　and　rapid　reliability　evaluation　method　of　LED　has　been　proposed.　The　pseudo-failure　lifetime　is　tested　and　the　lifetime　data　is　analyzed　by　Minitab.　The　results　show　that　the　pseudo-failure　lifetime　of　all　samples　are　Weibull　distribution.　The　reliability　evaluation　of　LED　products　are　made　by　comparing　the　scale　parameters　of　Weibull　distribution.　This　method　has　a　certain　reference　value　to　reliability　evaluation　and　life　prediction　of　LED.
