Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Field of Industrial Application) The present invention relates to a lighting device used in a stage, a studio or the like.

(Prior Art) This type of device has a plurality of level setting means including faders corresponding to each lighting load, and stores the lighting level of each lighting load for each scene set by these level setting means. Etc.

Conventionally, when setting, storing or executing lighting of such a lighting level, the number of each level setting means and its setting value are displayed on a CRT or the like, and a desired level setting means number is designated and the designated number is designated. It has been proposed that the lighting level of each lighting load can be set (including correction) by operating the level setting means.

(Problems to be solved by the invention) However, in the conventional one, since the correspondence between the level setting means and the actual lighting load was not displayed on the screen of the CRT, prepare a sheet in which the correspondence is entered separately, While watching this, the lighting level is set, and the operation unit of the level setting means is provided with a panel in which the correspondence is entered. However, all of these require level setting while looking at the sheet or panel and the screen, which impairs the operability of the operator. This problem becomes more remarkable as the number of level setting means increases. In addition,
For example, it is conceivable to input the above-mentioned correspondence by using a keyboard, but the input operation is still troublesome and is not a fundamental solution.

The present invention has been made in order to solve the above-mentioned conventional problems, and an object of the present invention is to provide a lighting device capable of significantly improving the operability of level setting.

[Structure of the Invention] (Means for Solving Problems) According to the present invention, a plurality of level setting means are provided corresponding to lighting loads and set the lighting level of each lighting load, and the above-mentioned level is set for each scene. A means for storing the level setting means number and each level setting value as lighting data; a means for reading and storing comment data on a sheet in which a preset relationship between the level setting means and each lighting load is written; It is characterized by comprising display means for simultaneously displaying the illumination data for each scene and the comment data on a common screen.

In the present invention, the level setting means can use a fader, a keyboard and the like, and the correspondence to the lighting load includes not only a fixed one but also a device whose correspondence can be arbitrarily changed as needed. .

Further, as the means for reading the comment data, it is preferable to use, for example, an optical scanning method, but other means may be used.

(Operation) In the present invention, since the display means simultaneously displays the illumination data and the comment data on the common screen, the operator can know the correspondence between the level setting means and the actual lighting load simply by looking at the screen. Therefore, when setting the lighting level of each lighting load, by selecting an arbitrary level setting means number while watching the comment corresponding to the lighting load and operating the level setting means of that number, the lighting of each lighting load is turned on. The level can be set.

Moreover, since the comment data is simply input by reading the comment written on the sheet, the operation is very simple.

In order to display on the screen, it is desirable that one level setting unit is horizontally expanded in the order of the level setting unit number, the level setting value and the comment. To achieve this, for example, the sheet in which the comment is written is standardized, and the display position of the level setting means number and the level setting value on the screen is restricted.

Further, the comment data is any one of the lighting load number, the type of lighting load (appliance), the light distribution, the light color, etc., or a mixture of them, and in short, what is useful to the operator when setting the level is properly used. Is.

Such a controller D is composed of, for example, a phase controller. C is a control device which outputs a control signal to the controller D to control the operation of the controller D. That is, by controlling the controller D, the lighting load L is lit at a desired lighting level. E is a cross connection which is used as required, and which can arbitrarily switch to which controller D (one or more) the control signal from the control device C is supplied, for example, a relay or a diode. Matrix and control device C
In the case of having a CPU, an A / D converter in the input section from the control signal generating section and the control signal output section of the control device C,
It is realized by switching the correspondence between D / A converters and the like. Note that the lighting load is shown in FIG. 7 for simplification.
Only one L and controller D are shown.

Next, the control device C will be described in detail below. 1 ₁ to 1 _n
