Abstract

Described herein is a luminaire controller for a luminaire in which dimming signals can be provided to control the operation of the luminaire. The controller also includes an energy measurement module connected to a mains supply, a sensor module, a power switch, a central processing module and a ZigBee transceiver module. The controller, in addition to providing dimming signals in accordance with ambient lighting conditions sensed by a photocell in the sensor module, provides efficient energy metering. In one embodiment, the luminaire controller is directly mountable on a luminaire for control thereof.
