New polarization-matched LED realizes 20% light output improvement

A polarization-matched LED co-developed by Rensselaer Polytechnic Institute and Samsung Electro-Mechanics has exhibited a 20% increase in light output and a 25% increase in wall-plug efficiency. And smart LEDs with the function of emitting light and handling date is in vision in the future, according to Professor Fred Schubert, the leader of the project.

RPI researchers use streamlined polarization to boost performance of LEDs

Researchers at Rensselaer Polytechnic Institute (RPI) have developed and demonstrated a new type of LED with significantly improved lighting performance and energy efficiency. The researchers worked in collaboration with Samsung Electro-Mechanics to develop the new polarization-matched LED that they say exhibits an 18 percent increase in light output and a 22 percent increase in wall-plug efficiency, which essentially measures the amount of electricity the LED converts into light.
