The LED light-source maker said on Tuesday that it has demonstrated the production of commercial LED light chips on silicon, a transition that will cut production costs by 75 percent and ultimately result in cheaper, more energy-efficient
light fixtures. Bridgelux intends to start making LEDs, which will be fitted into bulbs made by other companies, with the process in two or three years.Light fixtures with LEDs use semiconductors made by growing Gallium nitride (GaN) on a substrate of sapphire or silicon carbide. Using GaN on silicon, Bridgelux engineers have been able to get the same light quality and comparable efficiency as today's commercial products, the company said.http://www.zdnet.co.uk/news/emerging-tech/2011/03/09/led-maker-turns-to-silicon-to-lower-costs-40092075/
