Breakthroughs in light emitting diode (LED) technologies are catalyzing advances in solid-state lighting (SSL). SSL sources are already replacing conventional technologies in specialty applications, including automobile brake lights, traffic signals, exit signs, and flashlights. Further technology advances will drive the development of white-light sources that will ultimately replace incandescent and fluorescent lamps in general illumination applications.

Major research challenges must be addressed before the full promise of SSL can be realized. In partnership with industry, universities, research institutions, trade organizations, and national laboratories, DOE is accelerating the development of SSL technology. Through a series of ongoing, interactive workshops, DOE and SSL partners are refining an extensive research plan to ensure that DOE funds the appropriate research topics that will improve efficiency and move SSL into the marketplace.
