It has a scene selection operation unit for reproducing an illumination scene for lighting one or more of the plurality of illumination loads at individually set dimming levels, and outputs an operation signal according to the operation of the scene selection operation unit An operation device, a dimming device that is electrically connected to the operation device via a signal line and dimms and lights one or more illumination loads according to an operation signal from the operation device, and a desired partition pattern A partition pattern switching device that has a pattern selection operation unit for selectively selecting a partition pattern, and outputs a switching signal for switching the partition pattern according to the operation of the pattern selection operation unit to the dimming device ;
A light control device that receives an operation signal input from the operation device via a signal line, and a lighting load that is dimmed according to the operation of each scene selection operation unit in the current partition pattern A storage unit that stores the patch information for which the allocation of the scene is set and the scene information that sets the dimming level of the illumination load in each illumination scene, the operation signal received by the first communication unit, the patch information stored in the storage unit, and Ri formed and a control unit for turning on the lighting load dimmer corresponding to the original scene information, is stored a plurality of patch information corresponding to a plurality of partition pattern in the storage unit, the control unit, reads the patch information partition pattern selected on the basis of the switching signal from the storage unit, the dimming characterized that you change the allocation of the lighting load and the scene selection operating part Shi Temu. A plurality of the light control devices are provided, and the plurality of light control devices are electrically connected via the light control signal line and the operation signal line, and the operation signal received by the first communication unit to each light control device A second communication unit that transmits to the other dimming device via the operation signal line, and a third communication unit that communicates with the other dimming device via the dimming signal line, The control unit of each light control device receives the operation signal output from the operation device in response to the operation of the scene selection operation unit for which the correspondence relationship is set in advance, and receives the operation signal in either the first or second communication unit. Based on the operation signal, the scene information, and the patch information, the corresponding illumination load is dimmed and the dimming control signal is transmitted from the third communication unit to the other dimming device. Based on the dimming control signal, scene information, and patch information received by the third communication unit by the control unit Dimming system of claim 1, wherein the turning on the corresponding lighting load dimmer.
