DOE's research on LEDs for general illumination

The U.S. Department of Energy (DOE) has made a long-term commitment to advance the development and market introduction of energy-efficient white-light sources for general illumination. Solid-state lighting (SSL) differs fundamentally from today's lighting technologies, and its unique attributes drive the need for a coordinated approach that guides technology advances from laboratory to marketplace. DOE has developed a comprehensive national strategy that encompasses Basic Energy Science, Core Technology Research, Product Development, Commercialization Support, Standards Development, and an SSL Partnership.

Rapid progress in solid-state lighting (SSL) research and development (see DOE's SSL R&D Portfolio ) has resulted in the advent of light-emitting diodes (LED) for general lighting applications. In the section of the website provides information on the important performance characteristics of white light LEDs for general illumination, with particular emphasis on energy efficiency and lighting quality.
