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 TECHNOLOGY In conventional memory-type light control devices, each scene
The dimming level fl of the valley-1 path that dims each lighting load every time.
It was meant to remember and regenerate the negative. Such a dimming device has to store dimming level values for all circuits regardless of whether the lighting level of each lighting load changes, and requires a large storage capacity.

FIG. 1 is a graph showing the relationship between the scene and the dimming level value of each circuit for dimming one faint load in a conventional dimming device. In addition, Figure 2 shows the dimming level values stored in the circuit for each scene.The symbols marked with an asterisk (*) indicate that the dimming level changes for each scene in order to save storage capacity. It is shown that the real first festival is not memorized in the Shina i circuit. This will be explained below with reference to FIGS. 1 and 2.

For example, if the current state is set as scene 1 and skipping is performed to scene 4, the illumination load is dimmed when the pM light level reaches scene 4. However, in scene 4, only circuit 3 has memory of the dimming level cap, and 1L! When the dimming level value is not stored in the circuit 1 and the circuit 2 in advance, the IIs light level value in the scene 1 is maintained in the circuit 1 and the circuit 2. 2, the dimming level value becomes 2.

On the other hand, for the control panel, we expect that the scene will become wrinkled in the middle when jumping from scene 1 to scene 4, and we think that the light control level will be the same as scene 4. That is, fade control is performed to sequentially move from scene 1 to scene 4, and it is expected that the light will be dimmed in scene 4 at the same level as the dimming level reached in scene 4. In other words, even though we expected the dimming level to be 643 in circuit 1 and 2 in circuit 2, @
As shown in Figure 1, in circuit 1, the dimming level +aa, ta+
In path 2, the dimming level is at the end, 5. Since the adjustment circuit 3 has been stored in advance, the dimming level value 1 is obtained. In this way, the operator assumes that the desired dimming level cannot be obtained if the operator skips the step.

Purpose The purpose of the present invention is to solve the above-mentioned technical order and to
It is an object of the present invention to provide a light control device that can obtain the light control level for each scene that is desired by an operator by reducing k.

A sequentially counts the used circuits of the output section E that dims each lighting load. The memory circuit counter counts the circuit numbers stored in areas IB and 2B of the memory section B. Kd storage section B includes a circuit that changes the dimming level for each scene and 111' corresponding to the circuit.

Comparison kl 3 A compares the output circuit counter 4A2A and the circuit number 11 of the storage section B.
If there is a match, the jtf output section provides a match signal.O operation time 1

Each control signal is given to the scene kakunta 4A and the billion circuit kakunta 5A. The output section E always maintains the current dimming level for the old circuit, and only when it receives a match signal from the comparator 3A, outputs the memory section B corresponding to the match signal.
% (Q L
, and further provides a dimming signal to the negative lighting 411t.

Here, one example of scene skipping will be explained with reference to the flowchart shown in FIG. In step n1, an instruction is given to skip the scene. Then, the next scene is set in step n2. That is, the preset scene numbers up to the jump are set in the scene column 4A of the control section A. In step n3, the output circuit capacitor 2A is initialized. For example, the initial value 1+in is set to 1, and the initial value 1 is given to the comparator 3A.

At the same time, (b)g61 of the output section E corresponding to the content 1 of the output circuit capacitor 2A enters the write port I.

In this state, the memory circuit printer 5A is initialized in step. For example, the initial value f11 is set to 1, and the first circuit number value and its dimming level Iα of the area IB of the storage section B are read out in step n5. The circuit signal is applied to a comparator 3A, and its dimming level is applied to an output E Ic.

In step n6, the comparator 3A outputs the output reheating power 9 from the input circuit 41 and the circuit number I from the memory section B.
:a and if they match, the process moves to step n7, and if they do not match, the process moves to step n8.

In step n7, the current write river boat (path 1, for example, the dimming level value read from the storage unit B is written to (b) wkl of the output unit E due to the match fU from the comparison iq83 A. When the above-mentioned output part and the above-mentioned circuit number value do not match, writing to the output section E is not performed, and each circuit of the output section E maintains the same dimming level.

Next, in step n8, the memory circuit counter 5A is counted up. For example, if the hy light level of scene n is specified, the memory time; bath counter will be 2, 3, etc.・
..., tn is counted up.

In step n9, whether or not the memory circuit counter has reached in is 'l! When it has been reached, the process moves to step n1'0, and when it has not been reached, it returns to step n5.In step nlO, the output circuit counter 2A is incremented, and the K134 till path counter 5A is initialized. The output circuit counter 2A counts up to all the circuit numbers used in the output section E, for example 1, 2.
．． ...The count is increased to 1M.

In step nil, it is determined whether or not the count 11 of the output TpJ% counter 2A has reached M after kk.
At eight o'clock, return to step n4. In step n12, the scene counter 4A counts up. For example, if the current scene number is 11-1, the scene number 414
A is a foot step that counts up to nln+1! In step 113, it is determined whether or not the scene number 7419 in the scene counter 4A has reached the skipping scene specified by the sweeper. However, if it does not reach the target, the process returns to step n2. Because scenes are skipped by the above-mentioned rotations, 1) as expected by the operator in Figure 1 of the IS Chronicle, circuit 1 is based on rc:A and the bell value is 3, and circuit 2 is adjusted. You can get the light level box 2 and 1 it. Therefore, the operator can maintain the dimming level of the lighting load without locking even if the door is opened and the nine scenes are skipped. 1 Nao M! Control section A in Figure 3 can also be viewed on a ψ microcomputer.

Effects As described above, according to the present invention, the storage capacity of the storage means can be reduced, cost increases can be prevented, productivity can be improved, and lighting effects can be improved.
