Abstract:
1. A device, comprising: a light emitting diode (LED) including a plurality of III-nitride layers, wherein: the plurality of the III-nitride layers include an n-type layer, a p-type layer, and an active region between the n-type layer and the p-type layer that emits light, and an n-type side of the LED is on a front side of the LED, and a p-type side of the LED is on a back side of the LED opposite the front side; a transparent substrate or sub-mount attached to the p-type side of the III-nitride layers only; and one or more shaped optical elements combined with the LED and the transparent substrate or sub-mount, wherein the shaped optical elements and the transparent substrate or sub-mount extract light from the LED, such that the light is extracted through at least the front side and the back side of the LED.
