light-emitting diodes News
Enhanced LEDs Could Transform Lighting
Jul 27, 2004 — TROY, N.Y., July 27 -- A research team at Rensselaer Polytechnic Institute (RPI) has developed a new type of reflector that dramatically improves LED (light-emitting diodes) luminance. The National Science Foundation (NSF) recently awarded the research team a three-year, $210,000 grant to move the patented omnidirectional reflector to market. LED omnidirectional reflector developed by RPI researchers could brighten LEDs enough to replace the conventional light bulb. (Photo: Fred...
