RPI Scientists Seek More Efficient LED Technology

Article excerpt

TROY, N.Y.

Taking on a technical challenge that could revolutionize the lighting industry and reduce global energy demand, a top research team at Rensselaer Polytechnic Institute has garnered $1.8 million in U.S. Department of Energy funding to improve the energy efficiency of green light-emitting diodes, or LEDs. The Rensselaer research team will attempt to at least double the power output of green LEDs, which could then potentially replace incandescent and fluorescent lighting replaced in general illumination applications.

"Making lighting more efficient is one of the biggest challenges we face," says Dr. Christian Wetzel, an associate professor of physics at Rensselaer. "Substantial reductions in the nation's dependence on primary energy imports will be possible once highly efficient solid-state light sources replace wasteful incandescent and fluorescent lighting."

Wetzel is leading a team of scientists and engineers attempting to meet the aggressive performance benchmarks laid out by the Energy Department's Solid-State Lighting Program. …
