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

BACKGROUND TECHNOLOGY Conventionally, a light control device generates a signal for performing dimming control 11 of a lamp. In general, the 811 optical device Fi, as shown in Figure 1, consists of preset faders 2 that individually correspond to the lamps, and a master 7 fader l that collectively controls all preset faders 2. To do all the changes.

As shown in FIG. 2, preset faders PFI to PFn are arranged in multiple stages so that a large number of scenes can be set. A cross fader CF is also provided to enable smooth switching between preset faders PFI- and PFn.

The resistance value of the resistor A of the crossfader CF is 100%, the resistance 1m of the resistor B is 0%, and the variable resistance terminal Vi1 of the resistor A is

When set, the lamps can be dimmed and controlled using the vivid faders PFI to PFn, and the stage lighting can be performed. When the common contacts 01 to cn of the switches SW1 to SWn are set to all contacts b1 to bn, the lamps can be dimmed and controlled by the precent 7adas PF1 to PFn, and the lighting of the primary stage can be directed. NextNicros Feder CF resistance A resistance 1 night 100%
By simultaneously changing the resistance candy of resistance B from 0% to 100%, it is possible to continuously switch from E's vP stage performance to the next stage performance in Ut. In this way, by having m stages of PF1 to PFm, Q! 9 Hamade or I-

This is done using the main/tilt changeover switch 63 as shown in FIG.

The minimum pressure of the lamp of the load 79 is 1 degree. When the level of the main signal 91 is greater than or equal to the level of the fan signal 92, the lamp will emit light at the main input 91.Also, when the level of the main signal 91 is lower than the level of the signal 92, The lamp is dimmed by the tilt signal. Therefore, even if the level of the main signal 91 becomes zero, the lamp can be kept fully lit by the tilt signal 92.
As shown in (b), it is also possible to suddenly apply a tilt signal 92 higher than the level of the main signal (a) 91 to the lamp.

Effects As described above, according to the present invention, it is possible to completely switch between normal lighting and tilt lighting with a simple recitation 1r6 configuration. Since the user can visually check the comparison between the current dimming level and the 51.1 light level after tilting, the operation becomes convenient for the user.
