Abstract

A luminaire assembly comprises a housing, a plurality of light emitting diodes disposed within the housing, a microwave sensor disposed within the housing for detecting occupants in an area adjacent the housing, wherein the microwave sensor is in electrical communication with the light emitting diodes, and wherein the light emitting diodes are driven at a first light level and in response to the microwave sensor at a second light level.
