Origin of efficiency droop in GaN-based light-emitting diodes
Min-Ho Kim,Martin F. Schubert,Qi Dai,Jong Kyu Kim,E. Fred Schubert,Joachim Piprek,Yongjo Park +6 more
TL;DR: In this paper, the efficiency droop in GaInN∕GaN multiple-quantum well (MQW) light-emitting diodes was investigated and it was shown that the droop is not related to MQW efficiency but rather to the recombination of carriers outside the MqW region.

Prognostics of lumen maintenance for High power white light emitting diodes using a nonlinear filter-based approach
TL;DR: A nonlinear filter-based prognostic approach (the recursive Unscented Kalman Filter) is presented to predict the lumen maintenance of HPWLEDs based on the short-term observed data and is compared and evaluated with both accuracy- and precision-based metrics.
