#LEDs Replacing Venerable Street Lamps

Semiconductor makers have been concentrating on making brighter light-emitting diodes (LEDs), albeit at the expense of generating more heat in the process, but Oak Ridge National Laboratory (ORNL) claims to have a graphite-based solution. Look for LED-powered streetlights cooled by graphite foam from LED N.A. with in two years. RColinJohnson @NextGenLog



Here is what Smarter Technology says about LEDs: Oak Ridge National Laboratory claims to have surmounted the final hurdle to retrofitting streetlights with LEDs. Until now, LEDs burned out early when enough were amassed to illuminate a street. ORNL's carbon-based graphite material remedies the problem by keeping the LEDs cooler, an innovation it recently licensed to spinoff company LED North America for use in street lights, parking garages, industrial lighting and offices...
