  However, since the dimming controller shown in Patent Document 1 is provided with a separate fader unit for cutting off the output level during scene reproduction and correcting the output level, the components and controls that constitute the dimming controller A circuit is required, which may increase the size and cost of the device. Further, the dimming controller shown in Patent Document 2 needs to take into account the procedure for matching the output level at the time of scene playback to the output level indicated by the fader unit, and the user can immediately set the output level at the time of scene playback. It cannot be modified and is not efficient.

  The present invention solves the above-described problem, and when a scene is played back, the output level of the dimming operation signal actually output from the dimming controller does not match the output level set by the fader unit. Another object of the present invention is to provide a light control device that allows a user to efficiently correct an output level.

  In order to solve the above-described problems, the invention of claim 1 is directed to dimming that outputs a dimming control signal for dimming control of the lighting load to each of the dimmers connected to the plurality of lighting loads.

When the scene button is pressed to enter the scene playback mode and the output level set by the fader unit does not match the output level played by the scene playback unit, the control unit presses the changeover switch. As a result, the output of the dimming control signal according to the output level reproduced by the scene reproduction unit is cut off, and the dimming control signal according to the output level set by the fader unit is output. .

  Further, the invention of claim 2 is the dimming controller according to claim 1, further comprising an auxiliary storage unit storing an output level at which the output of the illumination load is approximately 50%, wherein the control unit includes the control unit When the scene button is pressed to enter the scene playback mode, and the output level set by the fader unit does not match the output level played by the scene playback unit, the changeover switch is pressed to The output of the dimming control signal according to the output level reproduced by the reproducing unit is cut off, and the dimming control signal according to the output level of the auxiliary storage unit is output, and then according to the output level set by the fader unit Dimming control signal is output.

  According to the first aspect of the present invention, when the changeover switch of the scene reproduction unit is pushed, the output level of the dimming control signal actually output from the dimming controller and the output level set by the fader unit are set. Since they match, the user can operate the fader unit to efficiently correct the setting of the output level while confirming the lighting state of the illumination load associated with each channel of the fader unit. In addition, there is no need to provide a separate fader unit or the like for correcting the scene setting, so there is no possibility of increasing the size and cost.

  Hereinafter, a light control device according to a first embodiment of the present invention will be described with reference to FIGS. 1 and 2A and 2B. The dimming controller 1 of the present embodiment performs dimming operation on a plurality of illumination loads 3 used in the illumination system 2 and is connected to a plurality of dimmers 4 connected to each of the illumination loads 3. Thus, a dimming control signal for dimming control of the illumination load 3 is output to each dimmer 4. The dimmer 4 has a switching circuit and generates high-frequency power according to the received dimming control signal. In the illumination system 2, a plurality of dimmers 4 are accommodated in the dimming panel 5. ing.

  The dimming controller 1 stores a plurality of fader units 6 for setting the output level of the dimming control signal output to the dimmer 4, and stores the output level set by the fader unit 6 as scene data. A scene reproduction unit 7 that reproduces an output level corresponding to the scene data, and a control unit 8 that controls the fader unit 6 and the scene reproduction unit 7 and outputs a predetermined dimming control signal to the dimmer 4. I have.

  The fader unit 6 sets a dimming control signal output level for controlling the brightness of each illumination load 3 for each channel associated with each of the dimmers 4. For example, the fader unit 6 is a slide-type variable. A resistor is used. The fader unit 6 is not limited to the slide type described above, and a part of the peripheral surface of the wheel interlocked with the encoder is exposed on the front surface of the dimmer 1 and the level is set by rotating the wheel. There is no particular limitation as long as the output level can be set for each channel, such as a level setting using a piano switch as an up / down switch. Each channel corresponds to a DMX512 control signal used in this embodiment.

  The scene playback unit 7 changes the output level of the changeover switch 71 and the scene playback unit 7 from the dimming control mode for performing the dimming control of the illumination load 3 to the scene setting mode for setting or correcting the output level of the scene playback unit 7. A scene storage unit 73 that stores a plurality of scene buttons 72 (scene 1 button 72a, scene 2 button 72b, scene 3 button 72c) to be switched to a scene playback mode to be played back and an output level set in the fader unit 6 is provided. The scene storage unit 73 is a general-purpose rewritable memory such as a RAM. The operation of the dimming controller 1 in each mode will be described later.

  In the dimming control mode, the control unit 8 detects the output level of the fader unit 6 and outputs a dimming operation signal corresponding to the detected output level to the dimmer 4. In the scene setting mode, the control unit 8 stores the output level indicated by the fader unit 6 in the scene storage unit 73 as scene data by operating the changeover switch 71, the fader unit 6, and the scene button 72, or reproduces the scene. In the mode, an operation of reading scene data from the scene storage unit 73 and outputting a dimming control signal corresponding to the output level of the scene reproduction unit 7 is performed. The control unit 8 includes a general-purpose microcomputer and a dimming signal generator (not shown). The dimming signal generator outputs a dimming control signal corresponding to the type of lighting fixture and dimmer to be dimming controlled, such as a PWM signal.

  Hereinafter, operations of the scene setting mode, the light control mode, and the scene reproduction mode of the light control device 1 will be described with reference to FIGS. In the following drawings, the button to be pressed or the fader portion to be operated is displayed with a stipple pattern. Further, the output level stored in the scene storage unit 73 as scene data is indicated by a thick arrow.

  First, as shown in FIG. 2A, the user pushes the changeover switch 71 to switch the dimming controller 1 from the dimming control mode to the scene setting mode. Either one is selected (scene 1 button 72a in the illustrated example), and the button is pushed. Subsequently, the user operates the fader unit 6 to set the output level of the dimming control signal output to the dimmer (illumination load) corresponding to each channel. Then, when the user pushes the changeover switch 71 again to cancel the scene setting mode, the control unit 8 outputs each output set for each channel of the fader unit 6 as shown in FIG. The level is read and stored in the scene storage unit 73 as scene data corresponding to the selected scene button 72a.

  Next, as shown in FIGS. 3A and 3B, the dimming controller 1 is set to the normal dimming control mode, neither the scene setting mode nor the scene playback mode is set. When the user operates the fader unit 6, the control unit 8 outputs a dimming operation signal corresponding to the output level set for each channel of the fader unit 6 to the dimmer 4.

  Subsequently, as shown in FIGS. 4A and 4B, when the user pushes the scene button 72 (scene 1 button 72a in the illustrated example) to switch to the scene playback mode, the scene playback unit 7 The output level corresponding to the scene data stored in the scene storage unit 73 is reproduced, and the control unit 8 does not display the output level set by the fader unit 6 but the output level of the scene reproduction unit 7 (FIG. 4A). A dimming operation signal corresponding to the thick arrow) is output to the dimmer 4. As described above, when the scene reproduction mode is set, the output level set by the fader unit 6 may not match the output level of the dimming control signal actually output from the control unit 8.

  In the dimming controller 1 of this embodiment, as described above, even when the output level set by the fader unit 6 and the output level reproduced by the scene reproduction unit 7 do not match, FIG. As shown in b), when the user pushes the changeover switch 71, the control unit 8 cuts off the output of the dimming control signal corresponding to the output level reproduced by the scene reproduction unit 7, and the fader unit 6 The dimming control signal corresponding to the set output level is preferentially output.

  That is, the output level of the dimming control signal that is actually output by the control unit 8 and the output level set by the fader unit 6 coincide. Therefore, the user operates the fader unit 6 to adjust the output level of the dimming control signal output from the control unit 8 while confirming the lighting state of the lighting load 3 associated with each channel of the fader unit 6. As a result, the scene setting can be corrected efficiently. Further, in the dimming controller 1 of the present embodiment, it is not necessary to provide a separate fader unit or the like for correcting the scene setting, so there is no possibility of increasing the size and cost of the dimming controller 1. .

  Next, a dimming controller according to the second embodiment of the present invention will be described with reference to FIGS. The dimming controller 1 of this embodiment further includes an auxiliary storage unit 9 that stores an output level at which the output of the illumination load 3 is approximately 50% in the dimming controller 1 according to the first embodiment. Is. For example, a general-purpose RAM or ROM is used for the auxiliary storage unit 9.

  In the dimming controller 1 according to the first embodiment, when the user pushes the changeover switch 71, the control unit 8 outputs a dimming control signal corresponding to the output level reproduced by the scene reproduction unit 7. The dimming control signal according to the output level set by the fader unit 6 is preferentially output, but for example, the scene reproduction unit 7 is similar to CH5 of the fader unit 6 shown in FIG. When the output level to be reproduced (thick arrow in the figure) is small and the output level (operation key) set by the fader unit 6 is large, the output level changes abruptly. There is a possibility that excessive stress is imposed on the optical device 4 and the illumination load 3. However, in the dimming controller 1 of the present embodiment, as shown in FIGS. 7A and 7B, when the user pushes the changeover switch 71 to correct the scene setting, the scene playback unit 7 plays back. The output of the dimming control signal according to the output level is cut off, and the dimming control signal according to the output level at which the output of the illumination load 3 stored in the auxiliary storage unit 9 becomes approximately 50% is output (FIG. 7). A thick arrow in (a)). Thereafter, as shown in FIGS. 8A and 8B, the control unit 8 blocks the dimming control signal corresponding to the output level stored in the auxiliary storage unit 9 and is set by the fader unit 6. A dimming control signal corresponding to the output level is output.

  As described above, the output level of the dimming control signal actually output from the control unit 8 and the output level set by the fader unit 6 via the output level at which the output of the lighting load 3 is approximately 50%. Since the output level is not changed suddenly, the stress on the control unit 8, the dimmer 4 and the illumination load 3 can be reduced.

  The present invention is not limited to the above embodiments, and various modifications can be made. For example, the control unit 8 further includes a detection unit that detects whether or not the output level of the scene playback unit 7 matches the output level set by the fader unit. The dimming control signal having an output level at which the output of the illumination load 3 stored in the storage unit 9 is approximately 50% is not output.
