ABSTRACT:
A digital lighting control system for controlling a plurality of lighting elements is provided, including a PC, a signal control unit, a signal conversion unit, and a signal dispatching unit. The signal control unit has a video signal input decoder for receiving video signal input and a PC display interface for connecting to the PC. The PC can control the lighting elements through the addresses of the lighting elements stored in the signal control unit. The signal conversion unit is connected to the signal control unit to receive control signals. The received control data is converted into data including addressing and control codes of the lighting elements. The signal dispatching unit is connected to the signal conversion unit for receiving converted addressing and control codes of the lighting elements. The signal dispatching unit dispatches the address and control code to lighting elements, which are connected to the signal dispatching unit. In addition, a plurality of signal control units can be serially connected to a PC, a plurality of signal conversion units can be serially connected to a signal control unit, and a plurality of signal dispatching units can be serially connected to a signal conversion unit. Therefore, a large area or various combinations of lighting elements can be controlled by the digital lighting control system.
