Integrated Reflector Could Lead to Ubiquitous LEDs

Andreas writes "Professor Schubert says he has found a way to raise the efficiency of LEDs to 99%. From an article on Advanced Technology: "Until now, all lighting systems, especially incandescent bulbs, generated more heat than light. But our 99-percent efficient reflectors for LEDs makes them the first candidate for light-bulb replacement that generates more light than heat," said Schubert."

These lights use a Fresnel Lens to direct the light from the bulb or LED cluster to only the lane for which it is intended.
