We analyzed the influence of a current aging on 380 nm band near-ultraviolet light-emitting diodes with different current densities. Aging have been carried out on LEDs with current densities of 5, 35 and 50 A/cm2 at room temperature for 1000 h. After stressed, both optical and electrical characteristics of LEDS are getting worse as increasing aging current density. We suggest that the possible degradation...
