Abstract:
An integrated multi-layer apparatus and method of producing the same is disclosed. The apparatus comprises an LED, a beam shaping layer, and a refracting layer between the beam shaping layer from the LED. The refracting layer may have an index of refraction lower than the index of refraction of the LED and the beam shaping layer.
