Description

DETAILED DESCRIPTION OF THE INVENTION Technical Field The present invention relates to a dIJ optical device for controlling relatively large-scale θ, 1-light equipment such as stage lighting.

BACKGROUND TECHNOLOGY Conventionally, Bt"d optical devices have created and used signals to control the dimming of lamps. In general, a dimming device has a preset fader 2 and a preset fader 2 individually corresponding to each lamp, as shown in FIG. , and a master fader 1 that collectively controls all preset faders 2. However, in order to change the scene in stage production, etc., the preset fader 1 is configured so that a large number of scenes can be set as shown in Figure 2. Fader PF
I to PFn are installed in multiple stages. Also, crossfader C
F is provided to enable smooth switching between stages of the preset faders PF1xPFn.

The resistance value to the resistor of the crossfader CF is 100%, the resistance value of the resistor B is 0%, and the variable resistance terminal of the resistor A is connected to the connection I5. of the switch swl of the stage selection section 4. a1, switch SW

are connected to each. Preset fader PFI~P
The other terminal of Fn is grounded. Input terminals of additions RNHI to Hn are connected to variable resistance terminals of preset faders PFI to PFn, respectively. The crossfader CF is
Master 7 is connected to the variable resistance terminal of Ada 1.

When the common contacts c1 to cn of the switches SW1 to SWn in P selection% 144 are set to the contacts a1 to an, respectively, (the lamp can be dimmed and controlled by the preset faders PFI to PFn, By setting the common contacts c1 to cn of the switches SW1 to SWn to the contacts b1 to bn, respectively, the lamps can be controlled by +1 light using the preset faders PF1 to PFni,'. It can be used to direct the lighting of a soft stage.

Next is crossfader C1? The resistance value of resistor A is 100%
from 0% to 100%, and the resistance value of resistance +1'CB from 0% to 100%.
By simultaneously changing to , it is possible to continuously switch from the current stage production to the next stage production.

In this way, by having m stages of preset faders PF1 to PFm, it is possible to
) You can set up to the tilted stage effect after the scene, sequentially,
The stage selection unit 4 and the crossfader CF can continuously switch the preset faders PFl to PFm.

Conventionally, the arrangement of the preset fader 31 r, :h qr
', As shown in Figure 3, there is a channel in the horizontal direction and 1 in the direction of the pattern.
4′ called death! It was fixed at 4 times 1. Controlling the same lamp #1. Since the preset 7adars 31 for creating the lj optical signals were lined up in one row, the internal light level differences for each of the several types of ti performance scenes were obvious at a glance from the position of the preset fader 31'.

However, when the number of controlled lamps increases and the number of preset faders increases, the 40゛1 row of preset faders used to create the same scene as the scene becomes very long, and the setting operations become more difficult. The number of human resources has become necessary.

q,'rK Recently, I stored the p-stage production scene in memory,
The memory of playing it sequentially! Ill light has also been developed to save labor. Although it has become possible to save labor during memory playback, it has not yet been put into practical use when setting scenes for ↑,'L production. It is an object of the present invention to provide a light control device that solves the problems and saves labor in setting operations for the stage lighting scene.
