Abstract
A light emitting diode device includes a multi-layer stack of materials including a p-layer, a n-layer, and a light generating region for emission of light in a primary emission direction towards one of the p- and n-layers; a substantially transparent layer located at or adjacent said one of the p- and n-layers, having a first surface facing said one of the p- and n-layers and an opposed second surface; and a reflective surface formed at or adjacent the second surface of the transparent layer for directing at least a portion of the emitted light in a direction away from the primary emission direction so as to enhance light emission from a side of the light emitting diode device.
