In the dimming control system configured as described above, the scene data stored in the scene memory 8 is reproduced by operating the scene controller slave unit 1 forming a remote control panel. The main scene controller 4 can set (prepare) the dimming level of each scene in the rendering time zone of the area, and the scene data of a plurality of channels, which is a combination of the set dimming levels, is stored in the scene memory 8. Is stored. Further, the main scene controller 4 can reproduce scene data. FIG. 3 shows the operation panel P of the main scene controller 4. In order to set the scene data by the main scene controller 4, first, the desired scene number is set by the numeric key 26. CP at this time
U11 determines the type of the key (switch) SW and turns on the LED 17 of the switch of the corresponding scene number. Next, the setting / reproduction changeover switch 27 is pressed to switch to the setting mode. LE showing the setting mode at this time
D lights up. Then, the number key 26 is used to set the channel to be set. After the channel is selected, the level up switch 28 or the level down switch 29 is operated to set the dimming level. After setting, push the level change stop switch 30. Here, level up switch 2

At the same time that the output level is changed by the soft timer based on the data of 4, the level is D / A converted and sent out to the corresponding channel output through the demultiplexer 20. Similarly, level setting is performed for other channels. When the setting is completed, the changeover switch 27 is pressed to switch to the reproduction mode. The scene data set at this time is stored in the scene memory 8. In order to reproduce the scene data, it suffices to select the scene number with the numeric keys 26, and at this time, the scene data stored in each channel is read from the sea memory 8.

The reproduced scene data is vertically adjusted in the scene controller 4 based on the detection signal from the weather sensor 24. If the weather sensor 24 detects a low outside light level or a rain condition is detected, the scene can be corrected to the initially set illumination level by correcting to increase the dimming level. The corrected scene data is converted to an analog signal by the D / A converter and then output to the dimmer 31 in the dimmer 5. The dimmer 31 produces a dimming control signal based on the scene data, and the dimming control signal controls the dimming level of the illumination load for each scene. As a result, the illumination level of each area can be changed for each production time zone, and a comfortable illumination space suitable for the scene can be produced. When a scene data reproduction operation is performed from the scene controller slave unit 1, control data for reproduction is sent to the transmission unit 3 via the transmission line 2 and the main control data sent from the transmission unit 3 corresponds to the main data. Scene data is read from the scene memory 8 of the scene controller 4.
The read scene data is corrected based on the detection output from the sensor 24 and then sent to the dimming board 5 to be used for creating a dimming control signal.

The main scene controller 35 can set and reproduce scene data, and the set scene data is stored in the built-in scene memory 8. Further, the transmission line 2 extending from the transmission unit 3 is connected via a transmission interface 42 to a remote control operation device 41 capable of operating the plurality of main scene controllers 4 and 35, respectively. When this remote control operation device 41 is operated, operation data is sent to the transmission unit 3. The transmission unit 3 decodes the input data and sends the control data to the corresponding main scene controllers 4 and 35 together with the address data. As a result, the scene data in the main scene controllers 4 and 35 can be rewritten and reproduced. For example, when the scene data is reproduced from the scene memory 8 in the main scene controller 35, the scene data is sent to the dimming terminal 40 via the transmission line 38 together with the address data.

Since the scene controller slave unit and the main scene controller are connected across the transmission unit, the main scene controller can operate even if the transmission line extending from the transmission unit to the slave unit is disconnected. There is no problem that all functions are stopped by disconnecting. Further, in the dimming control system according to the present invention, since the dimming level of the scene data can be corrected based on the detection output of the weather sensor, there is an effect that a more suitable lighting production suitable for the scene can be performed.
