ABSTRACT:
An (Al, Ga, In)N and ZnO direct wafer bonded light emitting diode (LED) combined with a shaped plastic optical element, in which the directional light from the ZnO cone, or from any high refractive index material in contact with the LED surface, entering the shaped plastic optical element is extracted to air.
