A group control function that can control a plurality of terminals connected to a lighting fixture with one switch;
The terminal to which the lighting equipment is connected has a group setting function that allows the user to freely select the control target of the group control by remotely operating the group setting switch. It is limited to group setting switches and terminals connected to transmission lines, and cannot perform group control and group setting across a plurality of multiplex transmission lines. In another system, a control device capable of managing one transmission line is connected via a network, and as a result, control over the transmission line can be performed.

Due to a large number of devices or a problem with the wiring of transmission lines, a situation in which transmission lines under the control of a plurality of control devices must be installed within one floor occurs. Therefore, it is not possible to set terminal control and group control under different management, so it is necessary to design the transmission line while paying attention to the floor layout from the time of construction. In the worst case, lighting one section on the floor The control must be performed a plurality of times with a plurality of switches that are expected to be installed in other places under the control of another transmission line, which is very inconvenient. Further, in a system configured by a network, the configuration is only complicated, and the performance corresponding to the capital investment cannot be obtained.

The present invention has been made to solve the above problems, and an object of the present invention is to provide a lighting control device with improved operability and workability.
