Description

[Detailed Description of the Invention] Technical Field The present invention relates to a light control device for controlling the light of a stage or the like.

Background Art Figure 1 shows the operation panel 1 of a conventional light control device.
FIG. The basic operation on this operation panel 1 is to input the predetermined circuit number of the dimmer circuit that dims and drives each lighting load using the numeric keypad 3, and press the set switch 5. comes under the control of the rotary encoder 2, and the lighting load connected to the dimming circuit is dimmed. Furthermore, if a plurality of the dimming circuits are specified using the numeric keypad 3, the plurality of dimming circuits perform a dimming operation. When the dimmer circuit is designated with the numeric keypad 3 and the release switch 3 is then pressed, the dimmer circuit that has been controlled by the rotary encoder 2 is no longer controlled. In other words, it is removed from the control of the rotary encoder 2. In such a conventional dimmer device, the dimmer circuit is controlled by the rotary encoder 2, that is, the dimmer circuit changes the dimming level of the lighting load when the rotary encoder 2 is operated during preparation of scene dimming, and the dimmer circuit is controlled by the rotary encoder 2. The dimmer circuit in which the light is installed has the ability to know which lighting loads are to be dimmed. This is the flash switch 4 shown in FIG. 1, and when the flash switch 4 is pressed, the lighting loads of all the dimming circuits under the control of the rotary encoder 2 repeat bright and dark dimming. The flash switch 4 thus allows the operator to signal which dimming circuit is under the control of the rotary encoder 2. However, it is not possible to know which lighting load the dimming circuit that is about to be placed under the control of the rotary encoder 2 corresponds to since it cannot be displayed until the dimming circuit is placed under control of the rotary encoder 2.
Also, when many dimmer circuits are already installed, there is a drawback that it is not known which lighting load the dimmer circuit just installed is compatible with the flashing operation.

Purpose The purpose of this invention is to solve the above technical problems,
It is an object of the present invention to provide a light control device that can inform an operator of which lighting load a specified light control circuit corresponds to by using an input means.

Embodiment FIG. 2 is a block diagram of an embodiment of the present invention. Moreover, FIG. 3 is a front view of the operation panel 31 of the light control device according to an embodiment of the present invention. The key input means 11 shown in FIG. 2 includes a numeric keypad 23 shown in FIG.
Flash switch 24, set switch 25,
A release switch 26 and a grouping switch 27 are provided. The rotary encoder 12 is
An up-down signal for raising or lowering the dimming level of the lighting loads L1 to Ln is given to the CPU (central processing unit) 13. The memory 14 stores the lighting load L
Dimming data necessary for dimming from 1 to Ln is stored. The CPU 13 receives the dimming data from the memory 14, processes the dimming data from the memory 14 using the up-down signal from the rotary encoder 12 and the key input signal from the key input means 11, and stores the data in the memory 14 at the same time. It is given to the output control device 15. The output control device 15 is

1 to Tn. The phase control elements T1 to Tn control the power from the AC power source E given to each of the lighting loads L1 to Ln using a phase control signal from the output control device 15. Accordingly, the lighting load L1~
Ln is dimmed at each dimming level.

The operations when operating the numeric keypad 23, flash switch 24, and set switch 25 will be described with reference to the flowchart shown in FIG. CPU
Step 13 enters the start state, moves from step m1 to step m2, judges whether or not the flash switch 24 is pressed, and if it is not pressed, moves to step m6, and checks the switching states of the switches other than the flash switch 24. and perform other processing. At step m2, flash switch 2
If it is determined that 4 is pressed, step m3
Then, it is determined whether the circuit has been selected by the numeric keypad 23 or before the set switch 25 is pressed. If the circuit is selected and the set switch 25 is not pressed, the process moves to step m5, and output level data of 0%, 100% (50%) is given to the circuit specified by the numeric keypad 23, and data is outputted alternately at regular intervals. Controls the output of the output control device 15. Thereby, the lighting loads L1 to Ln are dimmed at bright and dark dimming levels.

On the other hand, if a state other than the above occurs in step m3, the process moves to step m4, where all the circuits controlled by the rotary encoder 12 are set to 0% and 100%.
The output control device 15 alternately outputs the data at regular intervals.
give to

After the above operations are performed, the process moves to step m7 and ends.

Referring to the flowchart shown in FIG.
The operation when operating the grouping switch 27 shown in the figure will be explained. The grouping switch 27 is
For example, when there are four circuits for dimming a lighting load, there are four switches, and each switch corresponds to one circuit. When the number of circuits increases, the numeric keypad 23
can control the grouping switch 27. For example, in the case of 8 circuits, set predetermined circuit numbers 1, 3, 5, and 8 to switch SW1 of the grouping switch 27, and
If you select , the rotary encoder 12 will have circuits 1, 3,
5 and 8 will be under control.

In step n2 of FIG. 5, it is determined whether or not the flash switch 24 is pressed. If it is not pressed, the process moves to step n6 and other processing is performed; if it is pressed, the process moves to step n3. In step n3, after the numeric keypad 23 is pressed, when the flash switch 24 is pressed, 0% and 100% data is given to the circuit controlled by the selected grouping switch 27, and the data is alternately given at fixed time intervals. Controls the output of the output control device 15.

At step n3, if the circuit is selected and the set switch 25 is not pressed, the process moves to step n5. In step n5, 0% is applied to the circuit.
100% (50%) data is given, and the output of the output control device 15 is controlled alternately at fixed time intervals.

When preparing the circuit using the numeric keypad 23 in this way,
After selecting a circuit with the numeric keypad 23, if you continue to press the flash switch 24 until you press the set switch 25, you can alternately apply bright and dark dimming levels to that circuit at regular intervals, and after pressing the set switch 25, The circuit controls the output of the output control device 15 alternately at two dimming levels at regular intervals. This allows the operator to know whether the circuit selected with the numeric keypad 23 corresponds to the lighting loads L1 to Ln.

Effects As described above, according to the present invention, it is possible to easily know which lighting load the circuit corresponds to before installing the circuit, thereby eliminating incorrect installation.
