Blue　GaN-based　power　LEDs　are　biased　by　negative　human　body　mode　electrostatic-discharge　(ESD)　before　and　during　the　aging　time,　and　the　characteristics　of　LEDs　are　analyzed　before　and　after　aging　experiment　and　ESD　stress.　It　is　found　that　the　generation　of　defects　in　active　region　and　cladding　layers　after　ESD　stress　could　finally　lead　to　degradation　of　LEDs.　The　defects　induced　by　ESD　could　be　restored　partly　in　the　early　aging.　However,　these　defects　can　cause　parameters　drift　more　seriously.　Moreover,　LEDs　could　be　more　sensitive　to　ESD　stress　and　have　lower　antistatic　ability　during　aging.
