DOE partners with leading researchers from industry, academia, and national laboratories to accelerate advances in solid-state lighting (SSL). Since DOE began funding SSL research projects in 2000, a total of 316 patents have been applied for or awarded.
Collaborative, cost-shared DOE R&D projects combine the technical resources of premier research institutions and national laboratories with the product development, manufacturing, and commercialization expertise of industry leaders. DOE invests in research projects that target the needed improvements in price, performance, and manufacturability to speed SSL technologies to market.
For a complete listing of current DOE SSL R&D projects, see the Project Portfolio.
LUMILEDS FURTHER EXCEEDS eqe MILESTONE IN AMBER LIGHT
With funding from DOE, researchers at Lumileds have achieved, in a laboratory prototype, an amber LED with external quantum efficiency (EQE) of 22% at current density of 35 A/cm2 and junction temperature of 25°C. Efficient red and amber LEDs are essential building blocks for next-generation lighting products, enabling the ultimate DOE efficacy targets and spectral design freedom in color-mixed white and color-tunable lighting applications.
