Ultra-efficient Organic LED Outshines Lightbulb
Not surprisingly organic LED’s are slowly starting to take off and they are saving some pretty decent power. I really can’t wait until some of the technology I have been reading about for over two years really gets into the home. It is a step closer for the replacement of the lightbulb though with Organic LED’s.
Electrical engineer Stephen Forrest of the University of Michigan, chemist Mark Thompson of the University of Southern California and their colleagues created the so-called organic LED by combining two layers of phosphorescent diodes–to release green and red wavelength light–and one layer of a fluorescent diode to supply blue wavelength light. Together, they produce white light much more efficiently than current incandescent or fluorescent bulbs. “A 100-watt bulb is about 15 lumens per watt and we’re at about 25 lumens per watt just on the lab bench,” Forrest says.
