ABSTRACT:
A light extraction plate can be used with a light emitting diode (LED) to efficiently extract and provide control over the spatial distribution of extracted light in terms of intensity and angle. The extraction plate can have millions of optical micro-elements and can be manufactured independently of the LED using conventional integrated circuit (IC) fabrication techniques. The extraction plate is preferably attached or bonded to an LED surface.
