Abstract
A control terminal includes an individual address setting section for setting a unique individual address, and a simultaneous control address setting section for setting a simultaneous control address common to the plurality of control terminals A simultaneous control address is commonly assigned to the control terminals to be subjected to group control. When an UP switch Sb or a DOWN switch Sc of an operation terminal for group dimming purpose is pushed, a transfer signal including the simultaneous control address is transmitted to a signal line Ls from a transfer controller The respective control terminals substantially simultaneously receive the transfer signal, thereby changing the intensity of illumination loads.
