Abstract: A luminaire may include a light engine comprising a plurality of LEDs arranged in one or more annular rows. The luminaire may include an optic. The optic may include an annular optic body having a light entrance side facing the plurality of LEDs and a light exit side opposite the light entrance side. A plurality of annular grooves may be defined within the light exit side, the plurality of annular grooves being coaxial with the optic body. A plurality of arc-shaped grooves may be defined within the light exit side. Each of the plurality of arc-shaped grooves may be convex relative to a center of the optic. Each of the plurality of arc-shaped grooves may intersect at least one of the plurality of annular grooves. The optic may be configured to produce a Unified Glare Rating of less than 28.

Abstract: An environmentally sealed light fixture for illuminating potentially hazardous environments. The sealed light fixture includes multiple light modules that are independently rotatable to customize the direction of light emitted from the fixture. The fixture is also modular and scalable, enabling additional light modules to be added to increase lumen output or area coverage. The sealed light fixture includes sealed light chambers, electronics chambers, and sealed connections between the modules for maintaining the integrity as well as concealing the wiring and electrical connections within the light fixture.

Abstract: A light fixture includes a fixture housing. In some examples, an optic that includes silicone and is at least 5 inches in diameter is coupled to the fixture housing, and the light fixture is compliant with standard UL-844. In various examples, a top cap assembly is coupled to the fixture housing natively or as a retrofit kit. The top cap assembly includes a top cap and an interface ring, and allows for the light fixture to be attached to an existing top cap.
