Abstract

A lighting fixture includes an LED light source that outputs light for general illumination in response to a drive signal, and a driver module configured to provide the drive signal in response to an intelligent lighting module (ILM) instruction. An ILM that is separate from the driver module is provided and has a first plurality of sensors, a first communication interface, a second communication interface, and first control circuitry. The control circuitry of the ILM is configured to communicate with at least one remote entity via the first communication interface as well as generate the ILM instruction for the driver module based on sensor data gathered from the first plurality of sensors, remote entities, or a combination thereof. The ILM instruction is provided to the driver module via the second communication interface and used by the driver module to control the drive signal for the LED array.
