Solid-state lighting designers honored

The U.S. Dept. of Energy’s (DOE) Energy Efficiency and Renewable Energy section has honored a number of companies, organizations, and individuals for developing and promoting solid-state lighting technology. The awards were announced at the DOE’s annual Solid-state Lighting R&D Workshop, a three-day event held in San Francisco Feb. 3-5.

The organizations recognized for developing light-emitting diode (LED) and organic LED technologies include:

* Rensselaer Polytechnic Institute , Troy, N.Y., was recognized efforts to improve the efficiency of deep-green LED epitaxial materials.
* Eastman Kodak Co., Rochester, N.Y., was honored for demonstrating breakthrough efficacies of 56 lumens/W in a hybrid OLED, with color coordinates that fall within DOE Energy Star parameters.
* General Electric Global Research , Niskayuna, N.Y., was honored for developing advanced phosphor systems to increase the efficiency of phosphor-based LED lamps.
* University of Florida , Gainesville, was recognized for achieving a record efficacy of 50 lumens/W in a blue phosphorescent OLED.
* Cree Inc., Durham, N.C., was recognized for improving their cool-white multi-chip LED prototype, demonstrating 107 lumens/W.
* Universal Display Corp., Ewing, N.J., was recognized for achieving significant white OLED performance with a power efficacy of 102 lumens/W.
* Philips Color Kinetics , Burlington, Vt., was recognized for improvements in their warm-white multi-chip LED PAR lamp prototype, demonstrating 69 lumens/W.
