A professor at RPI has created a three-layer reflective coating for LEDs which magnifies their output 20-30%. Hopefully the technology can be commercialized and further hasten the energy reduction brought on by replacing incandescents and flourescents with those efficient light emitting diodes. The coating, known as an omni-directional reflector (ODR), consists of a semiconductor, a dielectric material, and a silver layer. (via Buzzworthy)
