Not a Fan of LED Lights? UGA Researchers Get Them to Emit a Warmer Glow
Researchers have figured out how to get the efficient, environmentally-friendly lights to emit a warm glow, rather than the typical cold, blue light.
They're efficient, they're environmentally friendly, but LEDs — light emitting diodese — are not popular when it comes to indoor lighting. Consumers just don't seem to like their cold, blue light. Researchers at the University of Georgia hope to change that. According to a story in the Athens Banner Herald, physics professor Zhengwei Pan, graduate student Xufan Li, research professional Feng Liu and a handful of other scientists have created the first phosphor that allows LEDs to give off a warm light. Engineers, the story says, have figured out how to make LED lights warmer, by coating them with several different phosphors, each one emitting a different piece of the color spectrum. The problem is that the phosphors are temperature …
