Influences of Microhole Depth and SiO 2 Nanoparticle/Microsphere Passivation Layer on the Performance of GaN-Based Light-Emitting Diodes
Zih-Fong Wang,Wen-Chau Liu +1 more
TL;DR: In this article, a hybrid structure including 45° sidewalls, a microhole array, and a thin SiO2 nanoparticle (NP)/microsphere (MS) passivation layer is used to produce GaN-based light-emitting diodes (LEDs).

Color-consistent LED modules for general lighting
Christoph G. A. Hoelen,Peter van der Burgt,Paul Jungwirth,Matthijs H. Keuper,Kwong Man,Claudia Mutter,Jan-Willem ter Weeme +6 more
TL;DR: In this article, a color tunable Lexel downlight module has been developed based on mixing of multiple colors, which enables forward compatibility by well defined interfaces and optical properties that are decoupled from the actual performance and number of LEDs.

Light extraction analysis of AlGaInP based LED with surface texture
TL;DR: In this paper, a Monte Carlo ray tracing method is applied to analyze the light extraction characteristics of AlGaInP based LED with various shapes of surface texture, and regular, periodic arranged structures were fabricated on p-side-up AlgaInP LEDs through dry etching.
Modeling and Validating a Continuous Flow Ultraviolet Light Emitting Diode Water Purification Reactor
TL;DR: In this paper, the authors used computational fluid dynamics (CFD) and transport of diluted species to validate the use of the model for design optimization by duplicating concentration tracer tests accomplished in a laboratory with a prototype UV LED reactor at four different flow rates.

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.
