Abstract
Solid-state lighting has made tremendous progress over the past decade, with the potential to make much more progress over the coming decade. In this talk, we review the current status of solid-state lighting relative to its ultimate potential to be "smart" and ultra-efficient. Smart, ultra-efficient solid-state lighting would enable both very high "effective" efficiencies, as well as potentially large increases in human productivity. To achieve ultra-efficiency, phosphors must eventually give way to multi-color semiconductor electroluminescence; to achieve smartness, additional characteristics such as the ability to control light flux and spectra in time and space will be important.
