Solid-State Lighting

Artificial light has long been a significant contributor to the quality and productivity of human life. It expands the productive day into the non-sunlit hours of the evening and night, and even during the day it expands productive spaces into the non-sunlit (windowless) areas of enclosed dwellings, offices, and buildings. Because we value artificial light [...]

Solid-state lighting (SSL) is an emerging technology with the potential to surpass luminous efficacy limitations and to introduce new functionalities and designs in lighting. Based on semiconductor light-emitting diodes, SSL has made remarkable progress in the past decade to the point where it is now competitive with incandescent technology. There is much research and development [...]

Solid-State Lighting Energy Efficiency News Energy Frontier Research Center for Solid-State Lighting Science Lighting consumes roughly 22 percent of United States electricity, a roughly $50 billion per year cost to the U.S. consumer. Solid-state lighting (SSL) is an emerging technology with the potential to reduce that energy consumption by a factor of 3–6 times. Despite [...]
