Abstract
The present invention relates to a lighting network control system and the corresponding control method. The control system consists of controllers, routers and illuminators connected via the serial connecting signal wires. The controller stores the control images and pictures. It transmits the serial control signal to routers and illuminators. The illuminators read in turn the serial control signal to extract the specific segment and transmit the rest to next device. A router reads in turn the specific segment from the control signal for its own stage. According to the requirements of the control signal, it transmits the control signal to different lighting network branches that connect with it. In the present invention, independent control to individual illuminator in the lighting network is implemented with comparatively lower cost. Arbitrary addition or reduction of illuminator(s) causes no affection to the entire system but to modify the signal data in the controller(s).
