Modelling thermal properties of large LED modules
TL;DR: In this article, a thermal model of large LED modules is presented and a method of parameters estimation is described, which is verified experimentally by comparing the results of calculations and measurements of internal temperature of selected LEDs included in LED modules.

A generalized 2D and 3D white LED device simulator integrating photon recycling and luminescent spectral conversion effects
Wei-Choon Ng,Gergö Letay +1 more
TL;DR: In this article, the spontaneous emission spectra are embedded in ray tracing, and are allowed to evolve as the rays traverse regions of stimulated gain, absorption, and luminescence.

Performance Enhancement of White LEDs Through Phosphor/Silicone Composite Particles
TL;DR: In this article, prefabricated particles consisting of the phosphor and the silicone are used to reduce the settling of heavy phosphor particles in the silicone encapsulation, which is a root cause for variation of the correlated color temperature causing yield reduction in the fabrication of white light-emitting diodes.

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.
