Abstract: The present disclosure is directed towards a luminaire having an optical waveguide and a light source. The optical waveguide has a hollow cylindrical structure with a first surface and a second surface at the opposite ends of the cylindrical structure and an external surface and an inner surface extending between the first surface and the second surface. The light source illuminates the first surface of the optical waveguide. The external surface of the optical waveguide is constructed such that the light from the light source exits from the inner surface. The luminaire directs the light from the light source towards the nadir and prevents glare to the eyes of the people in the surrounding space.

Abstract: A luminaire assembly and a silicone optical array. The luminaire assembly includes a housing, a substrate, and a silicone optical array. The housing defines a light emitting chamber. The substrate has a plurality of light emitting sources, such as light emitting diodes, supported thereby in an array. The substrate defines a peripheral edge. The silicone optical array has a plurality of silicone optics formed in the silicone optical array. The silicone optical array is located so as to cover one side of the substrate and the plurality of light emitting sources. The silicone optical array may further include a silicone mat and a plurality of silicone optics formed in the silicone mat and being arranged in an array corresponding to the array of light emitting sources.

Abstract: A luminaire has a housing plate on which a circuit board rests. The circuit board has light sources for generating light and circuit board bosses. A lens is biased toward the circuit board and contacts a distal end of the circuit board bosses to press the circuit board against the housing plate.

Abstract: Aspects provide photo-control receptacles having contact terminals via which control signals can be communicated. In one aspect, a photo-control receptacle is provided. The photo-control receptacle includes an interface having a neutral conductor and a line voltage conductor. Each of the neutral conductor and the line voltage conductor can form a first electrical connection for providing power to a photo-control via alternating current. The photo-control receptacle also includes one or more additional contact conductors adjacent to the interface. The one or more additional contact conductors can form a second electrical connection for providing control signals to the photo-control.
