July 3, 2006—The US Department of Energy (DOE) recently announced the selection of five companies to develop commercially viable solid-state lighting products.
- Color Kinetics Incorporated plans to develop replacement LEDs for 60-watt incandescent light sources with a 4x increase in efficacy to 80 lumens per watt.
- Eastman Kodak Company seeks to increase performance in OLED devices to 50 lumens per watt at 1000 cd/m2.
- General Electric Global Research will build upon previous successful work that incorporates the use of novel nanophosphors to create white light from violet LEDs, with the target of replacing incandescent light sources reaching 96 lumens per watt at color rendering indexes in excess of 80.
- OSRAM SYLVANIA Development Inc. seeks to develop a phosphor white LED with high package efficiency, with the target of 80 lumens per watt.
- SRI International seeks to develop cavity OLED devices with a 5x increase in the external quantum efficiency over standard OLEDs at twice the brightness.
DOE funding recently led to a breakthrough for OLED devices, as a researcher from the University of Southern California (USC) used a fluorescent dye to build a white-light OLED that could be three times more efficient than incandescent light bulbs.
