When setting a scene, first, the mode switch M is pressed to switch to the setting mode, and the operation knobs C1 to C4 are slid to change the lighting loads 10 of the first lighting fixture 1 to a desired dimming level. (Here, it is assumed that the dimming level of each lighting load corresponding to the operation knobs C1 to C4 is set to 50%, 30%, 40%, and 80%, respectively, with 100% being fully lit). Then, when the remote controller 4 is operated toward the lighting control device to change the lighting load 20 of the second lighting fixture 2 to a desired dimming level (60% here) and then the scene switch S1 is pressed. The control means 51 stores the dimming level data of the lighting loads 10 and 20 of the first lighting fixture 1 and the second lighting fixture 2 at the current time in the storage area corresponding to the scene switch S1 in the storage unit 8. .

  In order to reproduce the scene, after switching to the operation mode by pressing the mode switch M again, when the scene switch S1 in which the scene is set in advance in the setting mode is pressed, the control means 51 causes the scene switch S1 in the storage unit 8 to be reproduced. Is read out from the storage area corresponding to the lighting fixtures 10 and 20 of the first lighting fixture 1 and the second lighting fixture 2, and a dimming command is sent to the lighting fixtures 1 and 2 in a very short time. By sequentially providing the dimming levels of the lighting loads 10 and 20, the dimming levels set by the scene switch S1, that is, the lighting loads 10 and 20 are adjusted in the order of 50%, 30%, 40%, 80%, and 60%. The light level is changed at the same time and the scene corresponding to the scene switch S1 is reproduced.

When the power is turned on again, the scene immediately before the power is turned off is reproduced. It has become. When the power is turned on again, the scene may not be reproduced, but dimming according to the slide position of the operation knobs C1 to C4 at the time when the power is turned on may be performed.

  As described above, the lighting load 10 of the first lighting fixture 1 connected to the lighting control device 3 and the lighting load 20 of the second lighting fixture 2 that is dimmed by a radio signal transmitted from the remote controller 4 are provided. The lighting control device 3 has a function of performing dimming control in a lump, and the dimming level of the lighting load 20 of the second lighting fixture 2 is adjusted together with the dimming level of the lighting load 10 of the first lighting fixture 1 by the remote controller 4. Since a scene can be set, even when a new lighting load is added in addition to the existing lighting load connected in advance to the lighting control device 3, both the existing lighting load and the new lighting load are illuminated. Dimming control can be performed collectively by the control device 3, so that convenience can be improved.

  The radio signal used in the present embodiment is desirably a radio wave medium. By using radio waves with less directivity compared to optical signals such as infrared rays as a medium, the radio signal transmission unit of the remote controller 4 does not have to be accurately directed at the reception unit of the illumination control device 3 or the second lighting fixture 2. Dimming and scene setting can be performed, and control failure due to mismatch between the transmission direction of the radio signal and the reception direction of the reception unit can be avoided.

Even in the state, the above scene setting and reproduction operations can be performed. Therefore, when changing the specification of the lighting control device 3, the lighting control device 3 can be configured without changing the specification of the device main body 31 by changing only the specification of the operation panel 30, thereby reducing the installation cost. can do. In addition, by providing electrical contacts (not shown) on the operation panel 30 and the apparatus main body 31, respectively, the operation panel 30 can be operated by contacting the respective contacts when the operation panel 30 is attached to the apparatus main body 31. I do not care.
