Why Invest in Solid-State Lighting R&D?

Breakthroughs in light emitting diode (LED) and organic light emitting diode (OLED) 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.
		DOE invests in SSL research activities that target improvements in six key areas: quantum efficiency, longevity, stability and control, packaging, infrastructure, and cost reduction. Technology advances in these key areas will result in cost-competitive SSL sources that provide better quality light and save energy.

The Department's support of SSL is essential to ensure the development of energy-efficient SSL technology. The focus of DOE's SSL R&D plan is energy efficiency - an emphasis that, without DOE leadership, may be lost on the path to commercialization. The Department's involvement in SSL technology development pushes industry to higher levels of efficiency than they might otherwise achieve.

The Department's support also maintains our nation's technology leadership. While the projected energy savings are significant, white-light sources represent a high-risk investment that industry is unlikely to fund in the near term. If our nation is to maintain its leadership position in SSL technology development, the U.S. must keep up with other countries' commitment to SSL initiatives. The results from DOE's collaborative, cost-shared projects will ultimately deliver substantial energy savings and position U.S. companies as global leaders in new products, systems, and service markets.
