DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a storage dimming device that dims a plurality of lighting loads based on contents stored in advance in a memory.

Conventional Technology For example, in a wedding banquet hall, multiple lighting loads placed in the banquet hall move with soft light as the bride and groom walk, and illuminate only the area where the bride and groom are walking. Illumination may be desired.

Referring to FIG. 11, seven lighting loads A are installed in the banquet hall.
~G are arranged, and the brightness of these lighting loads changes according to the new part and the bride's walk 1 a, l b
,..., when trying to change each lighting load A to G, create a total of seven scenes for each lighting load A to G and store them in memory, as shown in Fig. 12. Two variable resistors R1 and R constituting the crossfader 5
The operator needs to operate the operation pieces 3.4 of 2 while selecting the scene.

In such prior art, the operations for sequentially reproducing each scene using a crossfader are complicated and require training. Furthermore, the lighting modes of each of the lighting loads A to G are limited, and furthermore, it is difficult to sequentially control the lighting loads A to G in various modes.

In addition, as shown in FIG. 4 (2) described in connection with the present invention, which will be described later, the lighting loads A to E are sequentially brightened from one end of the stage, for example, the left end, and the lighting load E at the other end, that is, the right end, is Conventionally, in order to control so that when the light becomes bright, all other lighting loads A to D also become bright, it is necessary to control each lighting load. A total of five scenes are stored and prepared in the memory for each lighting load A-E, and as shown in FIG.
~10. Each preset fader 6-1
Based on the output of 0, the brightness of each lighting load A to E is jul
It will be arranged.

Problems to be Solved by the Invention In the prior art shown in FIG. Preset faders 6 to 10 are required for each. Therefore, operations for the operator become complicated.

Although it is possible to automatically reproduce and produce the lighting control of the lighting loads A to E shown in FIG. 13, when doing so, it is necessary to The configuration is complicated, and it becomes impossible to adjust the brightness as desired by reversing the brightness control of each lighting load A to E.

An object of the present invention is to provide a storage dimming device that can control the lighting of multiple lighting loads in various ways with a simple configuration and operation.

Means for Solving the Problems The present invention comprises: a plurality of lighting loads; a fader having an operation piece and outputting an electric signal corresponding to the operation position of the operation piece; a lighting load to be powered;
A memory for storing a predetermined brightness of the lighting load; and a memory for reading the stored contents of the memory in response to the fader output, and energizing the lighting load to be energized at the predetermined brightness. A storage dimming device characterized in that it includes a control means.

According to the present invention, the lighting load to be energized and the brightness of the lighting load are stored in advance in the memory in accordance with the position of the operation piece of the fader. By operating the operating piece, the illumination load is energized at the predetermined brightness based on the stored contents of the memory corresponding to the position of the operating piece. As a result, the five configurations are simple, the operation is easy, and the dimming of the lighting load can be controlled in various ways.

Therefore, when changing the lights by following the movements of people in a banquet hall or on a stage, for example, the operation of the control panel can be done quickly and smoothly, and even people without training in operation can easily operate it. become able to. In addition, the so-called chaser function, which sequentially blinks multiple lighting loads, changes the lighting loads on and off according to the operation of the control panel, rather than the conventional fully automatic operation, at a speed corresponding to the speed of the control panel. A so-called manual chaser operation can be achieved. Furthermore, even an untrained person can perform various changes with simple operations. Furthermore, by sequentially turning on or off a plurality of lighting loads, it is possible to create an effect in which the light moves spatially with a simple operation.

Embodiment FIG. 1 is an overall simplified block diagram of one embodiment of the present invention. The brightness of the lighting loads A to G is changed and controlled by a dimming drive circuit 12 that performs conduction angle control. The lighting loads A to G are controlled by operating a console 13 equipped with faders 27 to 29 (see FIG. 2, which will be described later). The faders 27 to 29 are realized by variable resistors, and the output thereof is a voltage of, for example, 0 to 15V.

The outputs from the faders 27 to 29 are given to the voltage conversion circuit 15 from the line 14 and sent to the line 16 from 0 to 5.
It is converted to the voltage of analog digital conversion tIJ1 times 11
7 into an 8-bit digital value, line 1
8, the signal is input to a processing circuit 19 realized by a microcomputer or the like. A read-only memory 20 and a random access memory 21 are connected to this processing circuit 19 . The digital signal calculated in the processing circuit 19 is given to a digital/analog conversion circuit 23 via a line 22, and a voltage value is derived on a line 24. The voltage signal on this line 24 is applied to a voltage conversion circuit 25 and converted into a voltage value of 0 to 15V, and is applied to the dimming drive circuit 12 via a line 26. As a result, the dimming drive circuit 12 adjusts the conduction angle corresponding to the voltage value.
Therefore, each of the loads A to G is dimmed and driven depending on the brightness.

A plurality of preset faders 27, a submaster fader 28, and a crossfader 29 are provided, and furthermore, a key manual means 30 realized by a plurality of keys or the like is provided. The preset faders 27 are operated to individually control the brightness of each lighting load A to G, and according to the present invention, the operation of the operating piece 32 of that one preset fader 27 Corresponding to the position, the selection of each lighting load A to G and the brightness of the selected lighting load are reproduced. The submaster fader 28 is.

It corresponds to each scene individually and is used to adjust the overall brightness for each scene. A crossfader is used to switch between two scenes.

~G each includes a plurality of illumination lights and configures each channel. When displacing the operating piece 32 of the fader 27, which is a variable resistor, from one end 34 to the other end 35 as shown in FIG. Brightness corresponds to lighting loads A to G. By displacing the operating piece 32 from one end 34 to the other end 35, the lighting load A is changed as shown by the line 11a.
Further, the brightness of the lighting load B is changed as shown by line 11b, and the brightness of the lighting load G is changed in the same manner as shown by line 11g.

In this way, when the new part and the bride walk in the wedding banquet hall 33, the lighting staff RA near the new part and the bride
-G is turned on, and the light can be adjusted according to the walking situation. For example, for lighting load A, the position and brightness between both ends 34 and 35 of the operation piece 32 are set in advance as shown in Table 1.

As shown in Table 1 and FIG. 4 (1), when displacing the operation piece 32 of the fader 27 from one end 34 to the other end 35, the illumination loads A to E are As it is displaced to the right of (1), it gradually becomes brighter, and 1
The brightness will remain at 00%. For example, the brightness of illuminating lamp A changes as shown by line e2a, and the brightness of illuminating lamp B changes as shown by line 12b. In addition, in FIG. 3 (2) and FIG. 4 (1).

As shown in FIG. 2, lighting loads A to D may be selected and their brightness may be adjusted. The selection of what should be done corresponds to the brightness of the lighting loads A-D to be activated.

Referring to FIG. 6, when the operation piece 32a of the fader 27a is set at the 100% position, which is the top of FIG. Depending on the position of the operation piece 32b,
Brightness can be changed up to 100%. When the operating piece 32a is set to the 50% position, for example, the brightness of the lighting loads A to D is changed up to 50% at the maximum, as shown by lines 13a to 14d.

The configuration of the present invention will be further described in detail with reference to FIG. FIG. 6 shows the position of the operation piece 32 of one fader 27 and changes in brightness of lighting loads A, B, and C, and shows the changes in brightness of lighting loads A, B, and C.

Therefore, even a person without special training in operating the fader can produce a variety of moving lights. Furthermore, compared to the conventional method of changing scenes using a cross fader, the present invention allows the scene change to be performed by operating a single fader, improving operability.

Furthermore, in the present invention, the so-called chaser function that sequentially blinks multiple lighting loads can be advanced at a speed corresponding to the fader operation speed, and can also be reversed, allowing dimming control in various ways. It can be performed.

Furthermore, according to the present invention, the number of scenes to be stored in the memory and the number of faders to be used can be reduced, the memory capacity can be reduced, and the number of faders can be saved. Also in the present invention.

As mentioned above, since the concept of time such as fade time and wait time is applied to the fader operation piece, it is easy to use even for those who are not trained in operation.
