Patent ID: 8787765

Claim:
A method for communicating between a controller and a lighting node, the method comprising: transmitting a command via a controller radio device of the controller to the lighting node for the lighting node to match a target illumination profile stored on the controller, the target illumination profile indicating a color coordinate or a color temperature, wherein the controller is a portable remote controller; receiving the command at the lighting node utilizing a node radio device and storing the target illumination profile on the lighting node; and generating illumination from the lighting node to match the target illumination profile by: producing a spectral content by the lighting node with at least a light emitting diode; and sensing the spectral content from the lighting node at the controller utilizing an optical sensor while the spectral content is produced; and transmitting the sensed spectral content from the optical sensor as feedback to the lighting node until the spectral content on the lighting node matches the target illumination; wherein said producing of the spectral content is adjusted based on the feedback of the sensed spectral content.
