- W2039339934 abstract "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 by detailed analysis of the acquired spectral data at above nominal currents. The method was validated by comparing the predicted values with the measured values at nominal current. The proposed method was tested on white LEDs (luminous intensity ranged from 5 to 20 cd) from five manufacturers (Nichia, Etgtech, Sansen, Daina, and Velleman). The results show that the intensity and color degradation and corresponding variability among different LEDs is significant and, therefore, should be considered with great care when designing highly demanding lighting products." @default.
