Abstract
A lighting and control system is described. One embodiment of the lighting and control system includes a lighting node and a controller. The lighting node may include a light emitting diode configured for illumination and further configured for optical communication with the controller, a node radio device configured for radio communication with the controller, and a node memory configured to store a node identifier and a group identifier. The controller may include an optical sensor configured to sense illumination of the lighting node and further configured for optical communication with the lighting node, a controller radio device configured for radio communication with the lighting node, and a controller memory configured to store a group identifier. The lighting node and the controller may each further include a power supply and a processor. In one embodiment, the lighting node and the controller belong to a wireless mesh network.
