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.

Capacitance Minimization in Offline LED Drivers Using an Active-Ripple-Compensation Technique
TL;DR: In this paper, an approach for low-frequency output current ripple minimization in offline light-emitting diode (LED) drivers is proposed based on the large-signal modulation of the LED converter duty-cycle so that the output ripple can be reduced and the required filtering capacitances of the converter can be somehow decreased.
