Solid-State Light Sources Getting Smart
E. Fred Schubert,Jong Kyu Kim +1 more
TL;DR: The high efficiency of solid-state sources already provides energy savings and environmental benefits in a number of applications, but these sources also offer controllability of their spectral power distribution, spatial distribution, color temperature, temporal modulation, and polarization properties.
Reference EntryDOI
Light Emitting Diodes
TL;DR: In this article, the properties of inorganic LEDs, including emission spectra, electrical characteristics, and current-flow patterns, are presented and the packaging of low power and high power LED dies is discussed.
Journal ArticleDOI
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.
Journal ArticleDOI
Optical thin-film materials with low refractive index for broadband elimination of Fresnel reflection
J.-Q. Xi,Martin F. Schubert,Jong Kyu Kim,E. Fred Schubert,Minfeng Chen,Shawn-Yu Lin,W. Liu,J. A. Smart +7 more
TL;DR: Optical thin-film materials with low refractive index for broadband elimination of Fresnel reflection were used in this paper, where the authors proposed a method to eliminate the reflection in optical thin-films.
Journal ArticleDOI
White light-emitting diodes: History, progress, and future
TL;DR: The history of white light-emitting diodes (LEDs) can be found in this paper, where the authors review the history of the conception, improvement, and commercialization of the white LED.
