Prototypes of a new type of white light LEDs will be brought out in about four months by Cyberlux, a specialized provider of light emitting diodes (LEDs). The product cost of this new type will be cut substantially than conventional LEDs and more light will be emitted.
In conventional pattern, the blue light emitted by a semiconductor is converted into white light through a phosphor. A phosphor is a thin film on a substrate which is placed in intricate proximity to the semiconductor. In LED manufacture, to position the phosphor is one of the more expensive steps.
To reduce cost, a sheet of polymer is used to substitute the phosphor in the coming prototype, and it can apply itself into the LED almost like a layer of shrink wrap. Stephen DenBaars from The University of California Santa Barbara's and Nobel Prize winner Alan Heeger have invented this technology.
What’s more, the prototype will be brighter than conventional LEDs, because more photons will pass the phosphor and emerge as white light because of technology from RPI.
LEDs are more power efficient than conventional lights though are higher priced. And they come in multiple colors, so you can decorate your house with them like Peter Max lives there, as this photo at the Lumileds headquarters shows.
