Abstract

A 40 year old semiconductor technology, Light Emitting Diodes (LEDs) has steadily improved performance and cost to a point where it will move from its home turf, signaling applications to the much larger market, general lighting. The white LEDs are building momentum at such a rapid rate that we predict a revolution in lighting comparable to blowing out the gaslights by Edison's incandescent lamp 100 years ago. One technology will compete for all applications from the smallest indicator lamp to the lighting system for sports stadiums. LEDs will provide superior performance and lower cost of ownership, at any point in this dynamic range of 11 orders of magnitude. A complete conversion to LED based lamps could reduce electricity consumption for lighting by up to 75% and reduce global coal production by approximately 600 Mtons/year. There is no single technology investment on the horizon with a better environmental benefits to cost ratio.
