DISTRIBUTED LIGHTING CONTROL SYSTEM
The Distributed Lighting Control System (DLCS) is based upon a distributed lighting system, which imbeds luminaire devices in structural materials such as ceiling tiles and wallboard. Each luminaire device is attached to a power network, and each luminaire device includes, or is directly associated with, an electronic circuit component that controls the activation and operation of the luminaire. In normal operation the power network is energized based on signals conveyed to the circuit through wireless means or through signals imposed upon the power grid. Said signals are generated by the DLCS-controller, which is resident within the structure that contains the DLCS.
