1. A waveguide, comprising:
- a waveguide body comprising a first face and a second face opposite the first face and a coupling cavity extending between the first and second faces and defined by at least one light coupling feature that extends between the first and second faces;
wherein at least one of the first and second faces is an exterior face of the waveguide body;
wherein the at least one light coupling feature comprises a plurality of distinct surfaces;
wherein each of the plurality of distinct surfaces comprises a first end abutting the first face and a second ending abutting the second face, and each surface of the plurality of distinct surfaces abuts another surface of the plurality of distinct surfaces at an oblique angle;
wherein the coupling cavity is adapted to receive a light emitting diode (LED);
wherein the coupling cavity is noncircular and nonrectangular in a cross-section parallel to at least one of the first face or the second face; and
wherein the plurality of distinct surfaces defining the at least one light coupling feature comprises at least one protrusion.

Abstract
According to one aspect, a waveguide comprises a waveguide body further comprising a first face and a second face opposite the first face and a coupling cavity comprising an extent between the first and second faces and defined by at least one light coupling feature that extends between the first and second faces. The coupling cavity is adapted to receive a light emitting diode and the coupling cavity is noncircular and nonrectangular in a cross-section perpendicular to the extent of the coupling cavity. Further, the at least one light coupling feature comprises at least one protrusion.
