Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a dimmer that controls a lighting load that is projected on a performer or a stage device on the stage of a theater or in stages of various halls.

[0002]

[Prior art]

 Generally, a dimmer corresponds to a mode switch that sets various modes of the output level for the lighting load corresponding to each channel of the lighting load, a plurality of preset faders that set the output level for the lighting load, and this preset fader. Control switch to set the output corresponding to the full level of the preset fader during the ON operation, and to control the lighting load with the output mode set by the mode switch while the operation switch is on. And a dimming control unit that controls the light. Here, a channel corresponds to a lamp as a lighting load in a ratio of 1: n, and a unit called a cue or a scene, which is made up of a single or multiple channels with each dimming level, is one after another. Lighting conditions are created by being executed.

By the way, in the conventional dimming device, when it is desired to manually change the output calculation level including the preset fader and the memory reproduction during the dimming operation, for example, a piano mode switch and an operation switch are used. Some of them are operated by operating a piano switch, for example, but they had only an output mode for setting the output corresponding to the full level (100% output) of the preset fader.

[0004]

[Problems to be solved by the device]

 With such a conventional dimming device, it is easy to quickly lighten the lighting load during dimming control, but on the contrary, when you want to turn off the light suddenly, you can use multiple preset faders provided for each lighting load. We must take measures such as reducing it to zero all at once. For this reason, it is not possible to deal with speedily because complicated operation is required. Furthermore, when trying to turn off the light of each channel during memory playback, it is necessary to perform a correction operation for dimming control by memory playback. , There are problems with more complex operations.

An object of the present invention is to provide a light control device capable of quickly and accurately turning off the light of each channel during the dimming drive control with a simple structure and a simple operation.

[0006]

[Means for Solving the Problems]

 The present invention provides a mode switch that sets the output mode corresponding to each channel of the lighting load, and an operation switch that sets the output during the ON operation corresponding to the multiple preset faders that set the level of the lighting load. Includes dimming control means that controls the lighting load in the output mode set by the mode switch while the operation switch is on, and sets the lighting mode to turn off all lighting loads on a channel-by-channel basis in the mode switch. An off mode switch is provided, and when the off mode switch is set to the off mode, the dimming control means responds to the on operation of the operation switch to turn off all the channel units of the lighting load that is turned on. The light control device is characterized in that it is controlled to operate.

[0007]

[Action]

 According to the present invention, the mode switch is provided with an off mode switch for setting the light-off mode. When the OFF mode switch is set to the OFF mode, the dimming control unit turns OFF all the lighting load channel units in response to the ON operation of the operation switch. Therefore, during dimming control, if it is necessary to suddenly turn off the light on a channel-by-channel basis, simply operate the off-mode switch in the mode switch and turn on the operation switch. It is possible to turn off the lights with, and it is possible to respond quickly and surely.

【Example】

 1 is a block diagram showing an electrical configuration of a light control device 1 according to an embodiment of the present invention, FIG. 2 is a perspective view of the light control device 1 shown in FIG. 1, and FIG. 3 is a schematic view of the light control device 1. It is an electric circuit diagram shown. The configuration of the light control device 1 will be described with reference to FIGS. 1 to 3. The light control device 1 includes an operation unit 2 and a display unit 3. The operation unit 2 includes a lap reproduction unit 2A, a fade reproduction unit 2B, and a setting unit 2C, and sets dimming data such as dimming level and fade time.

A display unit 3 including display units 3A, 3B, and 3C each realized by a cathode ray tube (abbreviated as “CRT”) or the like is provided near the operation unit 2. The fader number, lighting output (%), etc. during the period are displayed. In the desk of the dimming device 1 realized by the dimming operation console, the dimming control means 4 for controlling the lighting loads L1 to Ln is provided in association with the operation section 2, and is operated by manual operation or memory reproduction. For each channel of the lighting loads L1 to Ln, it operates so as to give a predetermined output level in the range of extinguished light (0%) to full level (100%) to the lighting load.

The operation unit 2 includes a mode switch 5, a plurality of stages of preset faders 6A and 6B, and operation switches 7A and 7B provided corresponding to a plurality of, for example, two preset faders 6A and 6B. . For the preset faders 6A and 6B in a plurality of stages, the output from the selected one stage becomes effective. The mode switch 5 is provided with four switches, that is, a lock mode key 8, a −mode key 9, a + mode key 10, and an off mode key 11, each of which is realized by a Piano switch. The lock mode key 8 sets an output mode in which the output level applied to the illumination loads L1 to Ln is fixed to the final calculation output determined by the output calculation level including preset faders 6A and 6B and memory reproduction described later.

On the other hand, the-mode key 9 sets an output mode in which the output level of the specified channel is changed to 100% level and the output levels of the other channels are changed to 0 level, and the + mode key 10 is set to the output mode of the specified channel. The output mode is set so that the output level is kept at 100% and the output levels of other channels are kept at the final calculation output. Further, the off mode key 11 sets an output mode in which the output level of the specified channel is kept at 0 level and the output levels of the other channels are kept at the final calculation output.

The preset faders 6A and 6B are formed by sliding resistors, and the output level applied to the illumination load can be set in the range of 0 to 100%, and the knobs are manually operated to the front side. It can be set to 0% by pulling it down to 100% level by pushing it up.

Next, the operation switches 7A and 7B are switches realized by piano switches. For example, the operation switch 7A controls the dimming control means 4 so as to give the output mode set by one of the keys of the mode switch 5 to the illumination load whose output level is set by the two preset faders 6A and 6B. The momentary switch is used to set the output that activates the. The output lasts as long as you hold it down and disappears when you release it. As the operation switches 7A and 7B, it is of course possible to use an alternate switch in which the output is maintained until being pressed once and then pressed again.

On the other hand, the dimming control means 4 is provided with a turn-off control means 12. The light-off control means 12 is activated while the off-mode key 11 is operated and one of the operation switches 7A and 7B is on-operated, and all the lighting loads L1 to Ln are output at zero. That is, the lights are turned off, and the on operation of any of the operation switches 7A and 7B is turned off so that the lighting loads L1 to Ln are restored to the original lighting level.

FIG. 4 is a time chart showing an operation state of the light control device 1, and FIG. 5 is a flow chart of the same. The operation of the light control device 1 will be described with reference to FIGS. 1, 4 and 5. First, in step n1, the dimmer 1 is started. Go to the next step n2, n5, n7 or n9 and judge whether the lock (LOCK) mode key 8, -mode key 9, + mode key 10 or off mode key 11 in the mode switch has been operated. , Set the output mode corresponding to the operated key.

When the lock mode key 8 is set, the process proceeds to the next step n3, the dimming control means 4 is activated, and the output corresponding to the final calculation output determined by the preset faders 6A and 6B is illuminated. It is given to the loads L1 to Ln. This output state is shown in the range up to time T1 in FIG.

-When the mode key 9 is set, the process proceeds to the next step n6, and if the operation switch 7A is pressed along with the operation of the dimming control means 4, for example, the switch 7A is pressed. The lighting load of the corresponding channel is given 100% output (full level), and the lighting load of the other channels is given output that changes to 0 output (zero level). This output change is continued while the operation switch 7A is pressed.

On the other hand, when the + mode key 10 is set, the process proceeds to the next step n8, where the dimming control means 4 is activated and, for example, if the operation switch 7B is pressed, the switch 7B is pressed. Throughout this period, only the lighting load of the corresponding channel is changed to 100% output, and the lighting loads of other channels are allowed to retain the current final calculation output. This output state is shown in the range from time T1 to T2 in FIG.

When the off mode key 11 is set, the process proceeds to the next step n10, and if the operation switch 7A is pressed, for example, the operation of the operation switch 7A is controlled by the dimming control means 4. While is being pressed, the lighting load of the channel corresponding to the switch 7A is changed to 0% output and turned off, and the lighting loads of the other channels are given continuously after the current final calculation output. Become. This output state is shown in the range from time T3 to T4 in FIG. When the operation switch 7A is released, the extinguishing control means 12 immediately returns to the non-operation state, and as a result, the lighting load of the channel which has been extinguished until now is immediately given the original calculation final output and is not extinguished. Returned to brightness.

Since the output control is performed based on the flow shown in FIG. 5 as described above, the off mode switch 11 and the operation switch 7 are turned on and off for each channel unit especially during the dimming drive control. It is possible to perform the operation easily and quickly by operating the two types of switches.

[0021]

[Effect of device]

 As described above, according to the present invention, the mode switch 5 is provided with the off mode switch 11, and the dimming control means 4 operates the operation switch 7 when the off mode switch 11 is set to the off mode. In response to being turned on, the lighting load channel unit is controlled to be turned off. Therefore, it is possible to quickly turn off the light of each channel, and this point can be quickly performed by a simple operation, especially in the dimming control during memory reproduction.
