Toward Smart and Ultra-effi cient Solid-State Lighting
Solid-state lighting has made tremendous progress this past decade, with the potential to make much more progress over the coming decade. In this article, the current status of solid-state lighting relative to its ultimate
potential to be “smart” and ultra-effi cient is reviewed. Smart, ultra-effi cient solid-state lighting would enable both very high “effective” effi ciencies and potentially large increases in human performance. To achieve ultra-effi ciency,phosphors must give way to multi-color semiconductor electroluminescence:some of the technological challenges associated with such electroluminescence at the semiconductor level are reviewed. To achieve smartness,
additional characteristics such as control of light fl ux and spectra in time and space will be important: some of the technological challenges associated with achieving these characteristics at the lamp level are also reviewed.
It is important to emphasise that smart and ultra-effi cient are not either/or,and few compromises need to be made between them. The ultimate route to ultra-effi ciency brings with it the potential for smartness, the ultimate route
to smartness brings with it the potential for ultra-effi ciency, and the long-term ultimate route to both might well be color-mixed RYGB lasers.
