February 25, 2009—Seven research and development (R&D) project teams were recently honored at “Transformations in Lighting,” the sixth annual US Department of Energy (DOE) Solid-State Lighting R&D Workshop, held in San Francisco, California. The three-day event brought together more than 400 researchers, manufacturers, lighting designers, utility representatives and many other industry insiders and observers interested in keeping abreast of the latest solid-state lighting (SSL) technology developments.
The following organizations were recognized by DOE for significant breakthroughs and achievements in 2008, representing research in light emitting diodes (LEDs) and organic light emitting diodes (OLEDs) conducted at large and small companies, universities and research institutions.
- Cree, Inc. was recognized for significant improvements in its cool-white multi-chip LED prototype, demonstrating 107 lm/W;
- Eastman Kodak Company was recognized for demonstrating breakthrough efficacies of 56 lm/W in a hybrid OLED, with color coordinates that fall within DOE SSL ENERGY STAR requirements for LED products;
- General Electric Global Research was recognized for their development of advanced phosphor systems to increase the efficiency of phosphor-based LED lamps;
- Philips Color Kinetics was recognized for significant improvements in their warm-white multi-chip LED PAR lamp prototype, demonstrating 69 lm/W.
- Rensselaer Polytechnic Institute was recognized for their efforts to improve the efficiency of deep-green LED epitaxial materials;
- Universal Display Corporation was recognized for achieving record-breaking white OLED performance with a power efficacy of 102 lm/W; and
- University of Florida was recognized for achieving a record efficacy of 50 lm/W in a blue phosphorescent OLED;
