Solid‐State Lighting: Toward Smart and Ultra‐efficient Solid‐State Lighting (Advanced Optical Materials 9/2014)

Abstract

The image shows an artist's abstraction of digitally controlled RYGB lasers color-mixed to create white light, created by Hanqing Kuang and George Wang. The long-term route to ultra-efficient and smart lighting might well be some variant of this architecture, as phosphors must give way to multi-color semiconductor electroluminescence. On page 809, the current status of solid-state lighting is reviewed by J. Y. Tsao et al., including some of the associated technological challenges.
