Abstract
A lighting fixture includes a housing channel and a heat sink assembly coupled to the housing channel. The heat sink assembly includes a heat sink base and a heat sink clamp that are coupled together via a fastener to retain a waveguide to the lighting fixture. In particular, the fastener is disposed at an acute angle relative to the respective waveguide. Further, the lighting fixture includes one or more light sources coupled to the heat sink base and oriented such that light emitted by the one or more light sources enters an edge of the waveguide. Furthermore, the lighting fixture includes an end cap that covers an open lateral end of the housing channel. Further, the end cap operates as an alignment bracket to couple the lighting fixture to a second lighting fixture adjacent the open lateral end of the housing channel of the lighting fixture.
