Abstract: A luminaire has a light emitting portion extending between first second end caps to define a length between the first end cap and the second end cap. The first end cap comprises a receptacle and the second end cap comprises a post both of which extend in an insertion direction. The receptacles are configured to closely receive the posts and the insertion direction is disposed transversely to the length. A method of assembling a luminaire assembly includes positioning a first end cap of a first luminaire over a second end cap of a second luminaire; moving the first end cap relative to the second end cap in the insertion direction; and inserting the post into the receptacle. An electrical connector on the first end cap may connect with a mating electrical connector on the second end cap to complete an electrical connection between the first luminaire and the second luminaire.

Abstract: An LED light fixture includes a heat sink structure, at least one LED board in thermal engagement with the heat sink structure, the at least one LED board having at least one LED emitter thereon, and an on-board connector on the LED board for connecting electrical wiring to the LED emitter(s). At least one enclosing member forms with the heat sink an interior space enclosing a corresponding LED board, the rigid enclosing member defining a wiring aperture therethrough in alignment with the on-board connector. The LED light fixture also has an exterior wireway structure including a one-piece duct which has an end portion engaged with the wiring aperture and forms a channel for wires to the on-board connector. The wireway structure further includes a single-piece rigid cover secured with respect to the enclosing member and enclosing the duct.

Abstract: A sensor module for a lighting fixture includes a light sensor and a sensor cover over the light sensor. The sensor cover includes a front surface and a light focusing surface opposite the front surface. The front surface is configured to face an area of interest that is generally illuminated by the lighting fixture. The light focusing surface is opposite the front surface and includes a number of lens sections, each of which is configured to focus light from a different portion of the area of interest toward the light sensor. By including a number of lens sections each focusing light from a different portion of the area of interest, a relatively large area of interest can be observed while maintaining desirable aesthetics of the sensor module.

Abstract: A LED lamp for use in an existing light fixture having an electrical receptacle comprises an at least partially optically transmissive enclosure and a base having an external size that may be the same size or smaller than an external size of the electrical receptacle. A LED assembly is operable to emit light when energized through an electrical path from the base. The base comprises a universal mounting mechanism for mounting the lamp to the light fixture. A surge protector and an electrical connector are positioned at least partially in the base and are in the electrical path. A heat sink comprises a first portion in the enclosure for supporting the LED assembly and a second portion external of the enclosure for dissipating heat. The base is connected to the heat sink.

Abstract: In one aspect, luminaires are described herein enabling independent thermal management of driver and LED assemblies. For example, a luminaire comprises a driver assembly vertically integrated with a LED assembly, the driver assembly comprising a driver heatsink having an interior in which a circuit board assembly is positioned, and the LED assembly comprising an array of LEDs and LED heatsink, wherein a barrier is positioned between the driver heatsink and the LED heatsink, separating convective cooling of the driver assembly from convective cooling of the LED assembly.
