MIT creates LED that cools its surrounding environment | News | Lighting

A group of researchers in the US have unveiled an LED which emits more light energy than it consumes in electrical energy.

Researchers from the Massachusetts Institute of Technology (MIT) unveiled the LED, which has a conventional efficiency of greater than 200 per cent.

This means that unlike traditional halogen lamps and newer LEDs, instead of producing heat this LED will instead cool its surroundings.

Lead researcher, Parthiban Santhanam of MIT, said: ā??The most counterintuitive aspect of this result is that we donā??t typically think of light as being a form of heat. Usually we ignore the entropy and think of light as work.ā?
Anyone have any info about these new LEDs?
