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.

Abstract: A lighting fixture includes a housing with an upper base panel and opposed end walls that collectively define an opening in which one or more lamps and one or more reflector panels are disposed. The lamps extend substantially along a longitudinal axis of the housing, between bracket subassemblies. Each bracket subassembly includes at least one captive hardware fastener, which is pre-installed in the bracket subassembly and designed to be movable relative to the bracket subassembly only upon application of deliberate force with respect to the captive hardware fastener. While the captive hardware fastener is movable for installation purposes, the captive hardware fastener is not readily removable from its corresponding bracket subassembly. For example, the captive hardware can include a self-drilling screw, the body of which extends between two substantially parallel members separated by a third member, which has a straight or curved geometry.
