Abstract
Abstract A main control device comprises a plurality of lighting-control signal generators for generating lighting-control signals whose contents can be analogously varied, and a keyboard for specifying the contents of mode signals corresponding to those of the lighting-control signals. The lighting-control signals are supplied to the terminal control devices through a signal line. Mode signals and address signals are supplied to the terminal control devices through the signal lines. A terminal control device selected by the address signal selects a lighting-control signal corresponding to a mode signal. The selected lighting-control signal controls the lighting of a lighting load by phase control.
