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.
