Abstract: An optical waveguide includes a body of optically transmissive material having a width substantially greater than an overall thickness thereof. The body of material has a first side, a second side opposite the first side, and a plurality of interior bores extending between the first and second sides each adapted to receive a light emitting diode. Extraction features are disposed on the second side and the extraction features direct light out of at least the first side and at least one extraction feature forms a taper disposed at an outer portion of the body.
