Department of Energy picks LED lighting projects

The development of solid-state lighting in the US receives a $10 million boost as the Department of Energy selects five applications focused on product development.

The US Department of Energy (DoE) has revealed details of five projects that it is funding under its solid-state lighting product development program.

The projects, which include a 30 percent cost-share, total $10 million in value. They include three focused on III-V LED technology and two based on organic LED materials.

Awarded via the DoE's National Energy Technology Laboratory, the projects are expected to contribute significantly to achieving the DoE's target of developing solid-state lighting with a product system efficiency of 50 percent by 2025.

Color Kinetics, General Electric Global Research and Osram Sylvania have been awarded the three projects that incorporate III-V LED technology.

Color Kinetics plans to develop replacement lamps for existing 60 W incandescent bulbs with an efficacy of 80 lm/W. It will develop what it describes as a novel hybrid-LED source that combines direct emission with phosphor down-conversion.

General Electric's research wing will focus on using novel nanophosphors to convert violet LED emission into white light. Also aiming to replace incandescent sources, it is aiming for an efficacy of 96 lm/W.

Osram Sylvania's target is to increase external quantum efficiency using so-called remote phosphors and a multi-layer thin-film coating technique to extract more light from LEDs.

The two OLED projects will be headed up by Eastman Kodak and SRI International.

The product development required under the project guidelines includes production of field-ready prototypes focused on a targeted market application with fully-defined price, efficacy and other performance characteristics.

All of the projects are covered under the DoE's "exceptional circumstances determination", which was issued in June 2005 and covers matters relating to the ownership of intellectual property (see link).
