A reflector housing is detachably coupled to an LED based illumination device and includes a flange having a surface facing the environment illuminated by the LED based illumination device. The reflector housing further includes a reflector having an input port that receives light emitted from the LED based illumination device and an output port through which light passes toward the environment. At least one sensor, such as a sensor for occupancy, an ambient light, a temperature, ultrasound, vibration, pressure, or a camera, microphone, visual indicator, or photodetector, is coupled to the flange such that at least a portion of the sensor faces the environment illuminated by the LED based illumination device. A reflector interface module configured to receive at least one signal from the sensor is coupled to the reflector housing. Additionally, a communications interface subsystem is configured to transmit and receive communications signals to and from the reflector housing.
