Description

DETAILED DESCRIPTION OF THE INVENTION TECHNICAL FIELD The present invention relates to a light control device for dimming and controlling a lighting load for performing lighting effects on a stage or the like.

BACKGROUND ART FIG. 1 is a block diagram showing a portion of the configuration of a prior art dimmer.

In FIG. 1, a fader number selection section 1 selects a plurality of faders (not shown) for setting the dimming level of a lighting load. The fader controls dimmers DIM1 to DIMn that dim the lighting load. Load selection switches S1 to Sn are dimmers.
They are connected in correspondence with DIM1 to DIMn, respectively.

With such a configuration, the fader number selection section 1
The output of the fader selected by is given to the dimmers DIM1 to DIMn via the load selection switches S1 to Sn, whereby the dimmers DIM1 to DIMn drive each lighting load in a dimming manner. For example, when the load selection switch S2 is turned on, the output of the fader selected by the fader number selection section 1 is given to the dimmer DIM2 via the load selection switch S2. device DIM
The lighting load connected to 2 is driven at a dimming level corresponding to the fader output.

However, in the conventional light control device having the configuration shown in FIG. 1, for example, when the number of load circuits driving lighting loads increases, the same number of load selection switches as the number of load circuits are required. The wiring work for such a load selection switch becomes complicated. Further, such a light control device has a drawback that the capacity of the operation section for controlling the light control of the lighting load is also large.

The load selection switch is graphically arranged on the operating section in correspondence with the arrangement of the lighting loads on the stage, and is designed to improve operability. Therefore, if the load selection switch is replaced with, for example, a numeric keypad switch, the operating section will certainly become smaller, but since it does not correspond to the arrangement of the lighting loads, the operability will be very poor.
Therefore, such a ten-key switch is not very practical and is not used at all.

FIG. 2 is a block diagram showing a portion of the configuration of another prior art light control device. In Figure 2,
Components corresponding to those shown in FIG. 1 are given the same reference numerals.

In FIG. 2, the fader number selection section 1 selects a plurality of faders (not shown) for setting the dimming level of the lighting load. Load name selection switch
FS1 to FSm are for selecting lighting loads corresponding to predetermined names. Ten key switch TKS1 to TKSm for load number selection is dimmer DIM1
~DIMn is selected. The output of the feeder number selection section 1 is the load name selection switch FS1~
FSm respectively. The outputs of the load name selection switches FS1 to FSm are given to the lighting loads DIM1 to DIMn via the respective load number selection ten-key switches TKS1 to TKSm.

Such a configuration allows for example dimmer DIM
If each lighting load connected to DIM 1 to DIM6 is an upper horizon placed on the stage so that it can be illuminated from above the stage, the load name selection switch FS1 is named upper horizon. However, upper horizon refers to the type of lighting load that is lit from above the stage. Therefore, when dimming the upper horizon lighting load connected to the dimmer DIM1, by turning on the load name selection switch FS1 and the load number selection numeric key switch TKS1, the selection in the fader number selection section 1 is performed. The dimmer DIM1 operates with the fader output, and the lighting load connected to the dimmer DIM1 is driven to dim.

However, the dimmer shown in Fig. 2 can select the name and number of the lighting load and drive the lighting load, but when the number of lighting loads becomes very large, the load name selection switches FS1 to FSm and the load Numeric keypad switch for number selection TKS1~TKSm
There will also be more. This increases the capacity of the operating section and also complicates the wiring.

Purpose The purpose of the present invention is to solve the above-mentioned technical problem,
To provide a light control device in which a lighting load can be selected by the name of the actual lighting load and wiring can be easily performed.

Embodiment FIG. 3 is a block diagram showing an embodiment of the present invention, and FIG. 4 is an electrical circuit diagram of the embodiment of FIG. In FIGS. 3 and 4, the fader number selection section 1, which is a level setting means selection section, has a plurality of faders (not shown), which are level setting means, for setting the dimming level of the lighting load, Select that fader output. The load name selection unit 2, which is a second group selection means, includes a load name selection switch FS1, which is an individual switching element that selects a lighting load corresponding to a predetermined lighting load name.
~FSm, and receives the output of the fader number selection section 1. The load number selection units 1a to 1ma include the first
Numeric key switches TKS1 to TKSm for selecting load numbers, which are load selection means, are provided, and the ten key switches TKS1 to TKSm for selecting load numbers select the dimmers DIM1 to DIMn, respectively, which drive the lighting loads in a dimming manner.

Color selection switches CLS1 to CLSm, which are second group selection means, are connected to the load number color connection parts 1b to mb.
and a color preparation switch which is the second load selection means.
CLRS1 to CLRSm are provided. The color selection switches CLS1 to CLSm receive the outputs of the load name selection switches FS1 to FSm of the load name selection section 2, and apply them to the color preparation switches CLRS1 to CLRSm. Color preparation switches CLRS1 to CLRSm are dimmer DIM1
~Filter color of each lighting load connected to DIMm,
In other words, a lighting load that generates light of a predetermined color is selected. Also, color preparation switch CLRS1
-CLRSm are for giving the outputs of the color selection switches CLS1 to CLSm to the dimmers DIM1 to DIMn.

For example, the filter color of a lighting load connected to the dimmer DIM1 is red, and in order to dim the lighting load, switch A1 and switch B1 are turned on. In other words, if you turn on the color setting switches CLRS1 to CLRSm that indicate the color of the filter installed in the lighting load, which are installed in each load circuit that dims the lighting load, in advance, the load name selection switches FS1 to FSm Combination with numeric key switch TKS1 to TKSm for load number selection,
Further, a desired lighting load can be specified by a combination of load name selection switches FS1 to FSm and color selection switches CLS1 to CLSm.

FIG. 5 is a block diagram schematically showing another embodiment of the present invention. The fader selection unit 54 and the dimmer 55 correspond to the fader selection unit 1 and the dimmers DIM1 to DIMn shown in FIG. 3, so their explanation will be omitted. The memory 51 has storage areas 6A to 6E as shown in FIG. 6, and the storage area 6A has a lighting load 5.
6, such as Upper Horizont (UH) and Lower Horizont (LH), are stored. However, upper horizon refers to a lighting load that provides lighting from above the stage, and lower horizon refers to a lighting load that provides lighting from below the stage. The lighting load 5 is stored in the storage area 6B of the memory 51.
The color of the filter included in the lighting load 56 is stored in the storage area 6C where the load number 6 is stored. A predetermined number of the dimmer 55 is stored in the storage area 6D of the memory 51, and a predetermined fader number of the fader selected by the fader selection section 54 is stored in the storage area 6E.

As shown in FIG. 7, the keyboard 53 includes an upper horizon designation key switch UH, a lower horizon designation key switch LH, a red filter color designation key switch R, a green filter color designation key switch G, a blue filter color designation key switch B, and a numeric key switch. 0 to 9, clear key switch C, etc.

Here, the operation of the keyboard 53 and the operation of the processing circuit 52 when specifying a lighting load will be described with reference to the flowchart shown in FIG.

In step n2, a load name of a predetermined lighting load is specified using the keyboard 53 as a first group selection means. For example, to specify the upper horizon lighting load, press the upper horizon specification key switch UH shown in FIG. This specifies the lighting load for the upper horizon. Next, in step n3, the operator determines whether to specify the load number of the lighting load, and if the operator decides to specify the load number, the process moves to step n4. In step n4, for example, when specifying load number 4 of the lighting load, the ten key switch 4 as the first load selection means shown in FIG. 7 is pressed. As a result, the lighting load with load number 4 in the upper horizon is designated, and as can be seen from the memory contents shown in FIG. 6, the lighting load has a red filter color and is a dimmer DIM4. Further, the fader selection section 54 as a level setting means selection section specifies the fader number 4. As a result, the lighting load with load number 4 is driven and emits red light.

On the other hand, if you want to specify the filter color, click
Move from step n3 to step n5, and in step n5 the seventh
A filter color is designated by filter name designation key switches R, G, and B as second group selection means shown in the figure. For example, to designate the filter color as red, press the filter color designation key switch R. As a result, in step n6, the processing circuit 5
2 searches the contents of the memory as an individual switching element as the second load selection means shown in FIG. 6, and selects load number 1 and load number 4 whose load name is UPPER HORIZON. Therefore, the lighting load with load number 1 and the lighting load with load number 4 are driven by the dimmer DIM1 and the dimmer DIM4, respectively.

As described above, in this embodiment, a load can be specified by a combination of a load name and a load number, or a combination of a load name and a filter color.

In the embodiment shown in FIG. 4, the color selection of the lighting load filter is limited to four colors, but it is not limited thereto. In the embodiment shown in FIG. 5, the entire dimming device can be downsized by implementing the processing circuit and memory using a microcomputer.

Effects As described above, according to the present invention, the operation for specifying the lighting load can be performed using the commonly used name of the lighting load, so the operation for selecting the lighting load can be performed quickly. Furthermore, since the number of wiring can be reduced compared to the conventional method, the cost can be reduced.

Further, according to the present invention, the setting work of the individual switching elements of the second load selection means can be performed while operating the first load selection means and checking the color of the lighting load. After setting the second load selection means in this way, the lighting load can be selected by specifying the load name using the first group selection means and then selecting the second load selection means.
The color may be specified using the group selection means.
Moreover, by specifying the color, the switching element of the second load selection means can be set to a plurality of dimmer DIMs.
When it is set to be ON for 1, DIM2, ..., DIM6, multiple lighting loads can be selected at the same time. To cancel these designations, it is only necessary to operate the switching element of the first group selection means according to the load name, and the operation can be performed quickly.

The load name and color are predetermined for stage lighting. Therefore, a skilled operator can control the lighting load without visually checking the selection means, and can perform lighting effects while concentrating on the stage.
