Abstract: A luminaire is provided including a housing and at least one peripheral compartment defined in the housing that is configured to receive a lighting element. A central compartment is defined in the housing and disposed laterally inwardly of the at least one peripheral compartment. The central compartment is configured to receive control and power components for the lighting element. At least one lens is disposed over the at least one peripheral compartment such that the central compartment is accessible when the luminaire is installed on a support surface without a need to remove the at least one lens.

Abstract: A sensor support for use with a lighting refractor includes a housing defining an interior cavity configured to receive and support a sensor for sensing at least one of motion or light. The sensor support further includes a locking structure operatively associated with the housing and configured to selectively attach the housing to a peripheral portion of a lighting refractor, and an aperture in the housing and arranged to expose the sensor to an environment around the lighting refractor. Sensor and lighting unit assemblies are also disclosed. A sensor assembly includes the sensor support and a sensor configured to sense at least one of motion or light. A lighting unit assembly includes the sensor support and a lighting unit having a refractor with a peripheral portion.

Abstract: A modular lighting fixture includes an elongate center support member defining a channel. At least one reflector panel is coupled with the center support member and extends laterally outward therefrom. The lighting fixture further includes at least one light guide having a first edge and an oppositely disposed second edge. The first edge of the light guide is mechanically coupled with the center support member. The light guide may have a curved cross-sectional shape in a plane perpendicular to a longitudinal direction of the center support member. At least one light emitting diode (LED) is disposed adjacent the first edge of the light guide, whereby light produced by the LED is directed through the light guide toward the second edge.
