Abstract
A waveguide body comprises a length from a first end to a second end along a longitudinal axis, and a coupling portion that comprises first and second coupling surfaces. The first and second coupling surfaces define, at least in part, an elongate coupling cavity along the entire length of the waveguide body and a surface located opposite the coupling cavity. The waveguide body further comprises first and second opposed sections extending along the length of the waveguide body. The first and second opposed sections further comprise respective first and second lower surfaces disposed at different first and second side section angles with respect to a first axis lying in a plane normal to the longitudinal axis. The first axis bisects the coupling portion. Among other things, such a waveguide may be included in a luminaire along with a light source.
