LEDs that emit a broad spectrum of warm white light on par with sunlight has proven tricky
By Michael Cooney, Network World — When to comes to offering warm yet visually efficient lighting, LEDs have a long way to go. But scientists with the University of Georgia and Oak Ridge and Argonne national laboratories are looking at new family of crystals they say glow different colors and hold the key for letting white LED light shine in homes and offices as well as natural sunlight.
According to the scientists, Light-emitting diodes, or LEDs, offer energy savings over incandescent and fluorescent lights and are easily produced in single colors such as red or green commonly used in traffic lights or toys. However building an LED that emits a broad spectrum of warm white light on par with sunlight has proven tricky, the scientists said. Read more.
