Light emitting diode emitting red, green and blue light

Abstract

A multicolor light emitting diode (MLED) is disclosed which can emit various different colored light at the same time. A R, G, B three color LED is formed in a common crystalline granule (chip), with an ultra violet light crystalline granule formed by GaN grown on a sapphire substrate, and the finished products are all transparent. The surrounding of the granule is plated with an insulated layer and then a reflection layer. The light excited by the light granule is emitted either from the front or the back surface of LED. After the excited light has passed through a wave length converting layer, it can be converted to a colored visible light. The entire crystalline granule may be completely formed into an ultra violet or blue light chip, with wave length converting layers so that the chip can emit red, green and blue colors.
