Description

DETAILED DESCRIPTION OF THE INVENTION Technical Field The present invention relates to a four-light device for controlling relatively large-scale light control equipment such as a stage I11 light.

BACKGROUND ART Conventionally, a light control device generates a signal for controlling the dimming of a lamp. Generally, a dimmer device ij, as shown in FIG. 1, a preset fader 2 corresponding to each lamp individually;
It consists of a master fader 1 that collectively controls all preset faders 2, but in order to change scenes in stage productions, etc., as shown in Fig. Fader PFI~P
Multi-stage installation of Fn! 4□I am doing it. In addition, a crossfader CF is provided, and a preset fader PFI・-PF
(7) Smooth switching between stages is possible.

Crossfader CF resistance A resistance M4k 100%,
The resistance value of resistor B is set to 0%, and the resistance value of resistor A is set to 1.
Contact point al of switch SWl of stage selection section 4, switch SW
2 contact a2. and a contact an of switch SWn. Further, the contact b1 of the switch S W 1 of the two-stage selection section 4 of the resistor B is connected to the contact b1. Contact b2 of switch SW2. and switch SW n O) connected to contact bn1. Ru. One terminal of the Bricent fader PFI is connected to the common contact c1 of the switch SWI.
One terminal of F2 is connected to the common contact C2 of switch SW2, and one terminal of Brisset Fader PFn is connected to switch SVi'
n common contacts cn, respectively. The other terminals of the preset faders PFI to Ppn are grounded. The input terminals of the calculators l1l-Hn are connected to the variable resistance terminals of the preset faders PFI to PFn. Connect the crossfader CF to the variable resistance terminal of master fader 1.

The common contacts c1 to cn'a of the switches S W 1 to S W n in the stage selection section 4 and the contacts a] to an are the first
When set, Lampke dimming fti can be controlled using the preset faders PFI to PFn, and the full brightness of the stage performance can be performed. Switch SW1-SW
n concentric contacts cl to cnk contacts l] If you set it to 1 to bn, the preset faders PIi 1 to P
Dim the lamp from FnK! ti can be controlled and the lighting of the primary stage can be produced.

Resistance 1i of resistance A of next Nikros fader CF? '+',
't'' From 100% to 0%, the resistance of resistor B (direction 0%)
By changing from 100% to 100% at the same time, it is possible to continuously switch from the current stage production to the next stage production. In this way, preset faders PF1 to PF
m k By having m stages, from the current stage production (
m-1) You can even set the stage direction after the scene.
The precent faders PFl''PFm can be continuously switched by the successive one-stage selection section 4 and the crossfader CF.

Conventionally, the arrangement of the preset fader 31 has been fixed in a configuration with channels in the horizontal direction and stages in the vertical direction, as shown in FIG. Since the Bricent faders 31 that create dimming signals to control the same lamp were lined up in one row,
Differences in light control levels for several types of stage production scenes were clearly visible from the position of the preset fader 31.

However, as the number of controlled lamps increases and the number of preset faders increases, the horizontal rows of preset faders needed to create one stage production scene become extremely long, and many people are required to operate the settings. It has become. Particularly recently, memory dimming has been developed that allows stage performance scenes to be stored in memory and then played back in their entirety, saving labor. Although it has become possible to save labor when playing back memories, labor savings have not yet been achieved in setting stage production zones.

the purpose The object of the present invention is to solve all the above-mentioned technical problems.

It is an object of the present invention to provide a complete light control device that realizes labor-saving setting operations for needle head lighting production scenes.
