Description

[Detailed Description of the Invention] Technical Field The present invention relates to a plurality of lighting devices that change the brightness and color of the lighting depending on each scene, such as stage lighting for plays or lighting for wedding reception halls. This invention relates to an N''6 light 4J system that can be suitably implemented in order to be able to create and produce scenes.

BACKGROUND OF THE INVENTION In such a dimming device, each lighting scene is prepared and created before the scene begins, and then slowly when moving from the previous scene to the next scene.

This allows for quick scene changes. This kind of scene change behavior.

It's called a "crossfade." In other words, a crossfade consists of each light changing from the brightness of the previous scene to the brightness of the next scene.

During the lighting performance, not only all the lighting lights change at once, but also
Some of the lighting lights change slowly i1 and 'Ct? There are times when I feel nervous. For example, a lighting lamp such as a spotlight that shines light on a person.1. Even if the other lights f and J change to the next scene (for example, a zone where all lights iJ go out), only the spotlight will change with a delay, and the person will be illuminated for a long time due to this force. This makes it possible to create an effect where one person is emphasized.

In the prior art, among such multiple lighting ㅅ, J.

The variable resistors 9 and 1 (1 are constructed so that the increase and decrease in their resistance values are opposite to each other. Therefore, by operating the crossfader 5, the increase and decrease in the voltage applied to the preset fader 6.7 is The brightness fader 6 is used to set the illumination status of the illumination lights 1a to 1n corresponding to the previous illumination scene.
Another preset fader 6 is set with the lighting condition of the next lighting zone. ing. In this way, by operating the variable resistor 9.10 included in the crossfader 5, the lighting scene set by the Bricent fader 6 is changed to the lighting scene set by the Bricent fader 7. The illumination condition changes, or vice versa, as set by the preset fader 7.

It corresponds to the light-Ll of 1a to 1n. In this way, the memory circuit 39 stores the Bricent fader 4 for each scene designated by the scene designation switches 37 and 38.

A memory 44 is provided for receiving signals from 9. Input setting switches 45a to 45nt:t.

The input setting switches 45a to 45n individually correspond to the illumination lights 1a to 1n, and by making these input setting switches 45a to 45n small, delay designations can be made to individually correspond to the scene designation switches 37, 38 and 39. The signal is stored in memory 44.

When writing into this memory 44, a switch 46 is operated. The delay designation signals corresponding to the input setting switches 45a to 45n for each scene designated by the scene designation switches 37, 38, and 39 via the lines 47a to 47n are individually led out to the lines 47a to 47n.

However, if you try to use a lighting lamp with low power consumption (incandescent lamp) and a lighting lamp with high γF power consumption in the same sunny day with the same brightness, the light will be 71? ,1
Since the brightness (r) is determined first from the characteristic of 1 ([1 brightness 1), if all the 1i111 optical signals are changed at the same time and cross-faded, only the light with low power consumption will be produced in November. It seems that the brightness of the next scene is reached first, and the transition between the brightness scenes does not seem to be smooth.So, let's take an example of a tree and a tree with a brightness of 11.
7. The light of power 11 is slowed down and cross faded, and J: Very low consumption? It can be seen that a lighting lamp with FF power and a lighting lamp with high power consumption are changing into the same rod. This effect is.

In other words, if you change the light intensity all at once, bright-colored lighting lights will inevitably become stronger ML'l, F@ It appears that the light is changing.Then, let's delay the change in the light colored lights.As a result, both the light colored lights and the dark colored lights appear to change in a circular motion. be able to.

Effects As described above, according to the present invention, it is possible to change the light M by delaying a certain number of illumination lights among a plurality of lights. This makes it possible to achieve the desired lighting effect. In addition, lighting lamps with low consumption gravity and lighting lamps with bright color light intensity are delayed compared to the remaining lighting lamps, so that the apparent change in the light intensity of all lighting 'J:1' is made uniform. You can also do it.
