Solid-State Lighting: Toward Smart & Ultra-Efficient Materials, Devices, Lamps & Systems

Faculty host: Jim Speck
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.
Jeffrey Y. Tsao is a Distinguished Member of Technical Staff at Sandia National Laboratories and Chief Scientist of its Energy Frontier Research Center for Solid-State-Lighting Science. His work involves integrated science, technology and economic modeling in solid-state lighting and other areas. He has a hobby interest in network models of knowledge production. His Ph.D is in Applied Physics from Harvard University, and he has also held research, teaching or management positions at MIT-Lincoln Laboratory, E2O Communications, Inc., and the Institute of Materials Research & Engineering in Singapore. He is a Fellow of the American Physical Society and a Fellow of the American Association for the Advancement of Science.
