In this paper, a current-accelerated method for fast estimation of the intensity and color degradation with corresponding variability of light-emitting diodes (LEDs) is presented. The method is based on automated periodical spectral measurements of emitted light of LEDs under different current loads, which include nominal and several different above nominal currents. The intensity and color degradation and corresponding variability among different LEDs at a specified current are estimated… CONTINUE READING
