Abstract
The present invention discloses a high brightness light emitting diode. The light emitting diode primarily includes a permanent substrate, a reflective mirror formed on said permanent substrate, an n-type cladding layer formed on said reflective mirror, and defining a higher port and a lower port on an upper surface thereof, an active layer with quantum well structure formed on said higher port of said n-type cladding layer, a p-type cladding layer formed on said active layer, a p-GaP layer formed on said p-type cladding layer, a metal contact layer formed on said GaP layer, a p-type ohmic contact electrode formed on said metal contact layer, and an n-type ohmic contact electrode formed on said lower port of said n-type cladding layer. By providing a gallium phosphide window and a reflective mirror, brightness of the LED can be promoted.
