An LED based illumination device includes an LED based light engine and a light control and communications gateway (LCCG). An LED driver in the LCCG receives a light control command via a lighting control Network interface and in response provides an an electical current that controls the amount of light produced by the LED based light engine. The lighting control network interface of the LCCG is communicatively coupled to a lighting control network. The LCCG additionally includes a building management network interface that is communicatively coupled to a building management network. Identification and operational data for a plurality of LED based illumination devices communicatively coupled to the lighting control network is stored in memory, and operational data is communicated from the LCCG over the building management network interface to a building management system communicately coupled to the LCCG over the building management network. |
