Description

DETAILED DESCRIPTION OF THE INVENTION Technical Field The present invention relates to a storage dimming device suitably used for stage or studio lighting production.

BACKGROUND TECHNOLOGY When using a memory dimmer to set the stage lighting level temporally prior to the performance of a play, etc.
In addition, when reproducing the lighting levels set during rehearsals, etc., various tasks such as setting up props on the stage are usually carried out in parallel. In particular, if the lights to the audience seats are turned off as during a performance, it becomes difficult to assemble the equipment on the stage, so the lights above the audience seats must be turned on during the above-mentioned work.

Additionally, in recent years, it has become common practice to dim the lights above the audience seats at the start of a performance and then turn on the stage lights, and lighting above the audience seats is now considered to be a part of the production effect. .

FIG. 3 is a block diagram illustrating a typical prior art dimmer 30. In the light control device 30, light control is performed by completely separate circuits for the lighting above the audience seats and the lighting on the stage. That is, the lighting above the audience seats outputs a signal to the output circuit 39 by operating the fader 37 for the audience seats. Output circuit 3
9 converts this signal into a signal for controlling the dimming unit U1a and outputs it. The dimming unit U1a performs phase control on the illumination level of the lighting load R1a according to the output signal of the output circuit 39, thereby performing dimming control.

Regarding the stage lighting, the output signal from the operation of the operation unit 31 or the dimming information output from the main memory unit 36 via the memory circuit 35 is transmitted to the arithmetic circuit 3.
2, and calculations are performed in conjunction with a fade progression (crossfade) between a set of illumination levels at each point in time (hereinafter referred to as a scene).

The output signal of the arithmetic circuit 32 controls the illumination level of each lighting load R11-R1n via a storage circuit 33, an output circuit 34, and each dimming unit U11-U1n.

The operation unit 31 controls each lighting load R in each scene.
The illumination levels of 11 to R1n are operated, and the crossfade between each scene is also adjusted. In each scene, the arithmetic circuit 32 calculates
The signal representing the illumination level L1 input to the arithmetic circuit 32 is output as is, and during the period in which the crossfade is performed, the crossfade time T
1. Signals representing the previous scene illumination level M1 and next scene illumination level L1 are input, and when time τ1 has elapsed from the start of the crossfade, a signal representing the illumination level N1 given by the following equation is output.

N1=M1+(L1-M1)·τ1/T1 (1) The storage circuit 33 stores the calculation result of the calculation circuit 32 and outputs it to the output circuit 34. Also, memory circuit 3
3 also remembers the lighting level M1 of the previous scene,
A signal representing the illumination level M1 of the previous scene is output to the arithmetic circuit 32 and the main storage section 36.

The output of the memory circuit 33 is input to the output circuit 34 and converted into a signal for controlling each of the dimming units U11 to U1n. Each dimming unit U11~U1
n performs dimming control by controlling the phase of each of the lighting loads R11 to R1n based on the output signal of the output circuit 34.

The output of the operating section 31 is directly inputted to the main storage section 36, or the output signal of the storage circuit 33 is inputted to the main storage section 36, and each illumination level, crossfade time, etc. in each scene are stored. Memory circuit 3
5 reads the illumination level of each illumination load R11 to R1n of the next scene from the main storage unit 36, and
Output to.

Below are the 4 steps when performing stage lighting control.
The operation of the two modes is explained below.

First, in the manual operation mode in which the illumination level is directly controlled by operating the operating section 31, each of the lighting units U11 to U1n of the operating section 31
When a corresponding fader or the like is operated, a signal corresponding to the operation is provided to the output circuit 34 via the arithmetic circuit 32 and the memory circuit 33. Output circuit 34
outputs a signal to each of the dimming units U11 to U1n, and each of the dimming units U11 to U1n outputs a signal to each of the corresponding lighting loads R11 to R1n according to this signal.
Controls 1n illumination.

At this time, if there are multiple stages of fader rows corresponding to each lighting load R11 to R1n, each stage of fader rows is set to the illumination level of multiple scenes, and crossfades are performed manually or automatically between the multiple scenes. can be done.

Next, in a mode in which signals output by operating the operating section 31 are directly stored, the output signals of the operating section 31 are directly sent to the main storage section 36 and stored therein. Therefore, in this mode, each lighting load R1
The illumination level can be stored without affecting the actual illumination of 1 to R1n.

In the mode in which the lighting conditions of each lighting load R11 to R1n are stored while being monitored, the output signal of the storage circuit 33 is also output to the main storage section 36, and the output signal of each lighting load R1n is
Memory is also performed at the same time as the dimming of 1 to R1n.

In the mode in which the last playback operation is performed, a signal representing the dimming level L1 of the next scene among the dimming levels of a plurality of scenes stored in the main storage unit 36 is read out to the storage circuit 35 at the start of the crossfade, and the arithmetic circuit 32. At this time, the crossfade operation may be realized by the crossfader (not shown) of the operation section 31, or the crossfade operation may be realized by the crossfader (not shown) of the operation section
It is also possible to store the crossfade time T1 and output it to the arithmetic circuit 32 via the storage circuit 35 together with the dimming level L1. Thereafter, the output of the arithmetic circuit 32 is transmitted to each of the lighting loads R11 to R1 via the memory circuit 33, the output circuit 34, and each of the dimming units U11 to U1n, as in the manual operation mode.
n, and dimming control is performed.

The light control device 30 described above can only perform simple control of light control for the audience seats. Such a function alone cannot fully utilize the illumination of the audience seats as one of the production effects. Moreover, since the fader 37, which controls the level of lighting for the audience seats, operates in a different manner from the operating section 31, which controls the dimming of the stage, there are problems such as easy operation errors.

Therefore, a method was considered in which the dimming control of the lighting above the audience seats could be performed using the same operation without separating it from the dimming control of the stage lights, but once the dimming information was stored, the dimming control of the lighting above the audience seats could be controlled. Since light information is also stored, it is not possible to change the lighting level between rehearsal and actual performance. Therefore, in order to turn on the lights to the audience seats during a rehearsal and turn them off during the actual performance, complicated operations such as setting the lighting level once again are required after the rehearsal.

The light control device 30a shown in FIG. 4 is such that the above two light control methods can be switched by a switch 38, and blocks corresponding to those in FIG. 3 are given the same reference numerals. It has been done.

A switch 38 is provided between the memory circuit 33 and the output circuit 34 in the light control device 30a, the terminal α1 of the switch 38 is connected to the memory circuit 33, and the terminal β1 is connected to the fader 37. In addition, the output of the output circuit 34 is for each lighting load R11 to R1n on the stage.
The light is applied to the lighting load R1a on the passenger seats via the dimming units U11 to U1n and the dimming unit U1a.

The light control device 30a operates in exactly the same manner as the light control device described above for illuminating the stage. Furthermore, when the switch 38 is switched to the terminal α1 side, the lighting above the audience seats can be controlled by the same operation as the lighting on the stage. Further, by switching the switch 38 to the terminal β1 side, it is also possible to manually control the dimming of the lighting above the audience seats using the fader 37.

In such a light control device 30a, after setting the lighting level of each lighting load R11 to R1n for each scene, the switch 38 is switched to the terminal β1 side during rehearsal, and the lighting level of the lighting above the audience seats is adjusted even during playback operation. is brightened by the fader 37. During the actual performance, the switch 38 is switched to the terminal α1 side, the stored lighting level is reproduced in the same way as the stage lighting, and dimming control is performed.

However, such a light control device 30a has a drawback in that a fader 37 dedicated to the audience seats is essential. Furthermore, it is necessary to set the dimming information for the lighting above the audience seats at the same time as for the stage lighting. For example, in a rehearsal, if you want to set the lighting information and work on the stage at the same time, you can either dim the lights above the audience seats and set the lighting as in the actual performance, or change the settings to the lights that are on. must be set in a mode that sets the lighting level without affecting it. When setting the dimming in a mode in which the signal output by operating the operation unit 31 is directly stored in the main memory unit 36 without affecting the lighting that is lit, changing the mode is time-consuming. In addition to this, it is not possible to set the illumination level while looking at the actual illumination, making it impossible to make minute adjustments to the illumination level.

The conventional technology has the problems described above.

Purpose The present invention solves the above problems and allows dimming information to be stored/reproduced with the same operation for both the stage and the lights above the audience seats. It is an object of the present invention to provide a storage dimming device that can selectively store an arbitrary illumination level, such as turning on the illumination without storing only the illumination level.

This is a storage dimming device characterized by storing information.

Multipliers P1 to 6 multiply each dimming level by the output from the storage level fader and provide the result to the storage means 6.
Pn, and the storage means 6 stores the dimming output level from the one individual contact α of the changeover switch 8 or from the multipliers P1 to Pn in the storage area. It is an optical device.

Embodiment FIG. 1 is a block diagram showing a light control device 10 as an embodiment according to the present invention. In the light control device 10, the light above the audience seats and the stage light are controlled by the same circuit system. That is, any lighting load among the lighting loads R1 to Rn is set as the lighting load on the audience seats, and the memory selection unit 7
The switches S1 to Sn corresponding to each of the lighting loads R1 to Rn switch the conduction/blocking state between the type corresponding to the lighting load on the audience seats and the type corresponding to the lighting load on the stage. lighting loads are distinguished.

In the light control device 10, an output signal generated by operation of the operation unit 1 or light control information outputted from the main memory unit 6 via the memory circuit 5 is input to the calculation circuit 2, and calculations associated with cross-fade are performed.

The output of the arithmetic circuit 2 is sent to a memory circuit 3, an output circuit 4,
Each lighting load R via each dimmer unit U1 to Un
Controls the illumination level from 1 to Rn.

In the operation unit 1, each lighting load R1 in each scene
A lighting level of ~Rn is set, and a crossfade between each scene is also performed.

In the arithmetic circuit 2, during non-crossfade operation, the illumination level L input to the arithmetic circuit 2 is output as is, and during the crossfade period, the crossfade time T, the illumination level M of the previous scene, and the illumination of the next scene are output. Level L
is input, and when time τ has elapsed from the start of the crossfade, an illumination level N given by the following equation is output.

N=M+(LM)·τ/T (1) The storage circuit 3 stores the calculation result of the calculation circuit 2 and outputs it to the output circuit 4. The memory circuit 3 also stores the illumination level M of the previous scene, and outputs a signal representing the illumination level M of the previous scene to the arithmetic circuit 2 and the memory selection section 7.

The output circuit 4 takes in the output of the memory circuit 3 and converts it into a signal for controlling each of the dimming units U1 to Un. Each of the dimming units U1 to Un performs dimming control by, for example, phase controlling the lighting loads R1 to Rn, respectively, based on the output signal of the output circuit 4.

The memory selection unit 7 includes switches S1 to Sn corresponding to each of the lighting loads R1 to Rn and a switch 8. When the switch 8 is switched to the terminal α side, the dimming of the stage lighting explained in the background art is performed. This allows dimming to be performed using the same operation as the dimming of the lights above the audience seats, without having to separate them.

When the switch 8 is switched to the terminal β side, only the type of output from the memory circuit 3 that goes through the conductive one of the switches S1 to Sn is sent to the main memory 6.
is input.

The output of the operation section 1 is directly inputted to the main storage section 6, or the output signal of the storage selection section 7 is inputted to the main storage section 6, and each illumination level and crossfade time in each scene are stored. The storage circuit 5 reads out the illumination levels of the respective illumination loads R1 to Rn of the next scene from the main storage section and outputs them to the arithmetic circuit 2.

Hereinafter, operations in four modes when performing dimming will be explained.

First, in the manual operation mode in which the illumination level is directly controlled by operating the operating section 1, the operating section 1
When a fader or the like corresponding to each of the lighting loads R1 to Rn is operated, a signal corresponding to the amount of operation is applied to the output circuit 4 via the arithmetic circuit 2 and the memory circuit 3. The output circuit 4 outputs a signal to each dimmer unit U1 to Un, and each dimmer unit U1 to Un outputs a signal to each corresponding lighting load R1 according to this signal.
~Control the lighting status of Rn. At this time, if there are multiple stages of fader rows corresponding to each lighting load R1 to Rn, each stage of fader rows is set to the illumination level of multiple scenes, and the cross fader is manually or automatically set between these multiple scenes. can be done.

Next, in a mode in which signals output by operating the operating section 1 are directly stored, the output signals of the operating section 1 are directly sent to the main storage section 6 and stored therein. Therefore, in this mode, the lighting level can be stored without affecting the actual lighting of each lighting load R1-Rn.

In a mode in which the actual lighting conditions of each of the lighting loads R1 to Rn are stored while being visually recognized, the output signal of the storage circuit 3 is also output to the storage selection section 7. When the switch 8 is switched to the terminal α side, storage is performed simultaneously with the dimming operation of each of the lighting loads R1 to Rn, as in the conventional case. When the switch 8 is switched to the terminal β side, the illumination level of the lighting load corresponding to the switch that is turned on among the switches S1 to Sn is stored, but the illumination level of the lighting load corresponding to the switch that is turned off is stored. Levels are not remembered.

In the playback mode, among the dimming levels of multiple scenes stored in the main storage unit 6,
At the start of the crossfade, a signal representing the dimming level L of the next scene is read out to the storage circuit 5 and output to the arithmetic circuit 2. At this time, the crossfade may be realized by operating a crossfader (not shown) of the operation section 1, or the crossfade time T may be stored in the main memory section 6 and the crossfade time T may be stored together with the dimming level L through the memory circuit 5. This may be realized by outputting the data to the arithmetic circuit 2. Thereafter, the output of the arithmetic circuit 2 is input to each of the lighting loads R1 to Rn via the memory circuit 3, the output circuit 4, and each of the dimming units U1 to Un, as in the manual operation mode, and dimming control is performed.

In such a light control device 10, during work such as a rehearsal, the switch 8 is set to the terminal β side, and among the switches S1 to Sn, only the switch corresponding to the lighting load on the audience seats is shut off, and the light control level is adjusted. Do not memorize. At this time, the lighting loads above the audience seats are turned on by manual operation. During the actual performance, the switch 8 is set to the terminal α side to perform normal playback operations.

In this way, the light control device 10 is realized which overcomes the difficulty of changing the light control state during rehearsal as described in the background art section. In addition, in the light control device 10, it is possible to selectively store the individual lighting loads R1 to Rn, so for example, only the lighting level of the lighting above the audience seats can be stored before or after the lighting level of the lighting load on the stage. This allows for flexible memory operations such as Furthermore, the configuration is simplified because an output circuit dedicated to the lighting load on the passenger seats is not required. Furthermore, since the lighting load on the stage and the lighting load on the audience seats can be dimmed using the same operation, there is no risk of erroneous operation.

In the embodiment, switch 8 and switch S
1 to Sn need not be of the type having a contact mechanism, and may be memory switches using random access memory or the like.

FIG. 2 is a block diagram showing a memory selection section 7a according to another embodiment of the present invention. Memory selection section 7a
When the switch 8 is switched to the terminal α side, the operation is exactly the same as when the switch 8 is switched to the terminal α side in the light control device 10 shown in FIG. When the switch 8 is switched to the terminal β side, each multiplier P1 to Pn has a
The output from the fader (not shown) corresponding to ~Pn and the output from the memory circuit 3 are input, multiplied, and output to the main memory section 6.

If a light control device incorporating such a memory selection section 7a is used, for example, during a rehearsal, the lighting load on the audience seats remains bright, and on stage, the lighting level on the audience seats can be adjusted while observing the actual lighting conditions. The lighting above the audience seats can be used effectively as a production effect.

In this embodiment, the switch 8 or the switch 8a can also be configured to be switched in accordance with the operation of a fader, for example.

Effects As explained above, according to the present invention, since the present invention has a control means for controlling the information to be stored, for example, the lights above the audience seats can be turned on during work such as a rehearsal, and the actual performance can be performed without making any corrections after the rehearsal. During a performance, light control can be performed in accordance with the stored light control information. Furthermore, it is possible to provide a storage dimming device that has flexible operability for individual channels, such as re-storing only an arbitrary channel.
