Abstract: An optical waveguide includes a body of optically transmissive material having a width substantially greater than an overall thickness thereof and including a first side, a second side opposite the first side, a central bore extending between the first and second sides and adapted to receive a light emitting diode, and extraction features on the second side. A light diverter extends into the central bore for diverting light into and generally along the width of the body of material. The extraction features direct light out of the first side and wherein at least one extraction feature has an extraction surface dimension transverse to the thickness that is between about 5% and about 75% the overall thickness of the body of material.

Abstract: An optical waveguide includes a body of optically transmissive material defined by outer edges and having a width substantially greater than an overall thickness thereof. The body of optically transmissive material includes a first side and a second side opposite the first side. An interior coupling cavity is defined by a surface intersecting the second side and extends from the second side toward the first side. The interior coupling cavity is disposed remote from edges of the body and is configured to receive an LED element.

Abstract: A waveguide body comprises a length from a first end to a second end. The waveguide body further comprises a central section extending along the entire length of the waveguide body and comprising a first thickness. First and second opposed side sections extend away from the central section along the length of the waveguide body and comprise second and third thicknesses, respectively, less than the first thickness. A coupling portion is located in the central section, wherein the coupling portion comprises first and second coupling surfaces defining at least in part an elongate coupling cavity extending along the length of the waveguide body. The coupling portion further comprises first and second control surfaces, and the first and second coupling surfaces are configured to direct light onto the first and second control surfaces. The first and second control surfaces are configured to direct light into at least one of the first and second side sections. The side sections comprise optical features to extract light out opposing sides of the at least one side section as the light propagates through the at least one side section.
