Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a light control device, and more particularly to a light control device suitably implemented for lighting control of stages, studios, and the like.

Conventional technology A large number of lighting loads such as incandescent lamps are used for stage lighting such as stages and large halls, but the circuits to which these lighting loads are connected require that the lighting loads be installed at certain locations (ceilings, floors, etc.) A unique circuit number and circuit name (for example, UH for Atsuba Horizon) are assigned depending on the name and purpose (Lower Horizont, Atsuba Horizont, Footlight, etc.). energized by power.

A dimmer is realized using a semiconductor switching element or the like, and by controlling the phase of the gate terminal of the switching element, for example, the amount of power derived from the dimmer is adjusted to obtain a desired illumination level for each circuit. be able to.

The dimming levels of these dimmers are individually controlled by dimming control signals derived from the operating section of the dimming device.

Multiple faders are arranged in the control section of the dimmer,
By operating this, the brightness of the dimmer and therefore the lighting load connected to it is controlled, and a dimming operation is executed.

Generally, one circuit name includes one or more circuit numbers, so when a circuit name or circuit number is assigned to one fader, one channel is formed that can be dimmed by the fader. The light control device is provided with a circuit connection means called a crossbar switch for forming a channel, and a control means for instructing the crossbar switch to form a desired channel.

FIG. 5 is a block diagram showing the configuration of a light control device 1 according to the prior art. The light control device 1 includes one or more lighting loads aO, at, ..., a placed on the stage.
A total of n dimmers bO, bl, b2 . =-,
bn (1!) and a total number m of dimmers to control one or more dimmers in the same state to obtain the desired brightness of the corresponding lighting load a. Fader fO.

fl, f2. ..., fm (generally referred to as f), the above-mentioned dimmer, and fader f can be connected in any combination, and the loss bar switch 2 and fader f can be connected in any combination.
Channel designating means 3 and load circuit designating means 4 are arranged for setting the connection combination mode between the dimmer and the dimmer.

Although it depends on the scale of the stage, the number of load circuits n is usually greater than the number of channels m, and multiple load circuits, that is, dimmers, can be combined and connected to one channel in one operation. ,used.

The channel instruction means 3 and the load circuit instruction means 4 are both realized by a plurality of input switches such as a numeric keypad, and the channel instruction means 3 selectively instructs the fader f, and the load circuit instruction means 4 causes The circuit name and circuit number are selectively indicated. The number of dimmers connected to one fader f is not limited to one, and the above connection combination information of the selected fader f and dimmer is a connection combination realized by storage means such as RAM. The information is sequentially stored in the information holding means (hereinafter referred to as memory) 5.

In the crossbar switch 2, a plurality of lines to which dimmers are individually connected and a plurality of lines to which faders f are individually connected are arranged in a grid, and a semiconductor switch or relay is installed at each intersection of the grid. The contacts of the switch to be realized are arranged, and the switch is driven by the connection combination information S read out from the memory 5. Therefore, according to the connection combination information S read out from the memory 5.

For example, a fader f1 and a dimmer b3 are connected to form one channel.

In a place where the dimmer 1 is installed, such as a theater or hall, the circuit name and circuit number, that is, the channel, of the dimmer load circuit that each fader has is predetermined. The individual connection modes of the fader f and the dimmer corresponding to each channel, that is, the connection combination information S, may be written in advance in the memory 5 at the time of installation. A case may also be considered in which a person performs a write operation to the memory 5.

Problems to be Solved by the Invention However, in order to write the connection combination information S into the memory 5, the numeric keys provided on the channel designating means 3 and the load circuit designating means 4 are pressed, and for example, the load circuit 1 ( Dimmer number = 1) → Channel 1 → Load circuit 2 (Dimmer number = 2) → Channel 1 → Load circuit 3 (
It is necessary to repeat the instruction operation such as dimmer number = 3) → channel 2 → load circuit 4 (dimmer number = 4) → channel 3...

As described above, the number of load circuits r1 is greater than the number of channels m, so the setting method described above requires a large number of operating procedures, which naturally increases the working time.

Therefore, there was a problem that work errors were likely to occur.

Furthermore, even if the connection mode has been determined and the connection combination information S has been written in the memory 5, it is necessary to change the already determined connection mode depending on an event that will be performed at a later date. For this purpose, the connection combination information S may be rewritten. In the conventional light control device 1, it is necessary to repeat the operation procedure each time such a situation occurs, resulting in low efficiency and poor workability.

An object of the present invention is to provide a light control device that solves the above-mentioned problems, reduces the number of operating steps, and improves work efficiency and reliability.

After being inputted to the conversion means 16 via line L5 and subjected to a data conversion operation described later, identification data, such as a dimmer number to be described later, is inputted to the first table memory 15 via line L2.

In this way, the correspondence relationship between the lighting load A, that is, the dimmer B and the fader F is stored in the first table memory 15.

The load circuit switch 14 includes a circuit setting switch 14a equipped with a plurality of numeric keys for indicating the load circuit name and load circuit number, and an address switch for calling up the dimmer number stored in the second table memory 16b. 1

Therefore, the circuit setting switch 14a is provided with a numeric keypad on which numbers and alphabets are written.

Further, the address switch 14b is connected to the second table memory 16.
The dimmer number b is marked with a + or - sign to increase or decrease the corresponding address.

The address is given to the table memory 15, and is also held in the address holding means 16a and stored as the previous call address. The above address specification is performed by the address switch 14b, and when subsequently specifying an address, the address held in the address holding means 16a is increased by +1 by simply pressing the + or one switch of the address switch 14b. It can be incremented or decremented by -1 to call and specify the dimmer number for the preferred cortex.

When newly writing connection information to the first table memory 15 or changing the already written contents depending on the content of the event, etc., first specify the channel, that is, the fader F using the channel switch 13, and then turn the fader F. F
The dimmer you want to assign to the address switch 14b
Press to recall from the second table memory 16b.
For example, assume that the connection information is currently stored as shown in Table 2, and if you want to change the assignment of dimmer B, which belongs to dimmer number B3, from fader F1 to fader F3, use the channel switch. Instruct F3 from 3°.

This instruction is sent to the first table memory 15 via line L1.
Next, press the + switch of the address switch 14b to read the address "3" of the second table memory 16b.
”, and input it to the first table memory 15 via line L2.
The fader number corresponding to the dimmer number B3 in the first table memory 15 is rewritten from Fl to F3. Furthermore, when writing the connection information for the first time, the fader number (J) is a space, so the fader number F3 is immediately written. In this way, creation and modification of connection information can be achieved with simple operations.

In the embodiment described above, in FIG.
Although the load circuit switch 3 and the load circuit switch 14 are shown as being separately provided, they are actually provided on the same operating panel. Also, the contents of the first table memory 15,
The contents of the second table memory 16b may be displayed on the operation panel by a display means (not shown).

FIG. 4 is similar to FIG. 3, and corresponding parts are given the same reference numerals.It should be noted that the channel switch 13 and the first
A changeover switch Sll is interposed between the table memories 15, and the line L1 can be connected to the second table memory 16b by operating the changeover switch Sll. Thereby, the priority cortical layer of the dimmer number stored in the second table memory 16b can be changed.

Since the priority differs to some extent depending on the performance purpose and the operator, it is extremely effective for operation to have a configuration for changing the priority.

Effects of the Invention As described above, according to the present invention, the correspondence between a plurality of lighting loads and a plurality of operating means is stored in the first storage means as connection information, and a condition predetermined for each of the above operating means is satisfied. identification data of one or more lighting loads to be stored in the second storage means; In setting the correspondence relationship in the first storage means, the corresponding identification data of the second storage means is read out and stored in response to the output from the address instruction means.
