No. 1012I is a flowchart called a PAD diagram for explaining the operation of the control unit 53 for realizing effect control in a conventional device. This operation in the control unit 53 is performed by an interrupt operation every 25m5ec. Effect control playback is performed in the order of playback effect numbers indicating the illumination state FF) at the time when effect 1iiiIItn is being executed.When the 1 interrupt operation is started, in step n1, the playback effect number i is The processing for each effect is performed sequentially from effect number 1 to effect number 4, for example. For each reproduction effect number i, in step 02, it is determined whether reproduction is instructed by the effect number. If the effect is not being reproduced, the process returns to step n1 and processing for the next reproduced effect number is performed. When the effect is being reproduced, the process moves to step r13, and the value of the variable SCi for calculating the step time is increased by 1. Note that the initial value of the variable SCi is zero. Next, the process moves to step n4, and the variable SC
The value of i is the predetermined maximum value of SCi 3 (: i m

5d to set the value of scimax in FIG.

Problems to be Solved by the Invention Conventionally, when the step time is shortened, the lighting time of the lighting load is also controlled to be shortened. However, since an incandescent lamp or the like is used as the lighting load, there is a problem that, especially when the capacity is large, the set dimming level cannot be reached in a short period of time, so that sufficient effect control cannot be obtained.

An object of the present invention is to provide a lighting effect device that can easily realize effect control based on a step time, which is a short reference time, for a large capacity lighting load.

Means for Solving the Problems The present invention provides: a plurality of lighting loads; and a reference time setting means for setting times at which each of the lighting loads should be dimmed and controlled at intervals of multiples of a predetermined unit time. , means for individually setting a lighting time for each of the lighting loads with respect to a reference time for each of the lighting loads; 1. A lighting effect device comprising: means for energizing.

According to the present invention, the reference time of a plurality of lighting loads is set at a multiple of a predetermined unit time, and the light is controlled to be dimmed. Regarding the reference time for each lighting load, the time for lighting each lighting load can be individually set and energized with power.

Therefore, by setting the lighting load to be given time to reach the set dimming level, even if the predetermined unit time becomes shorter, it will still be sufficient for a large capacity lighting load. Time power energization can be done.

The data set as shown in FIG. 3 is intended to realize the effect control shown in FIG. 9. However, if the step time adjustment wheels 58 to 5d are adjusted to shorten the step time, which is the interval between each reference time, the time during which each lighting load is energized with power becomes insufficient as described above.

In other words, the step length adjustment wheel is a time setting means. In this way, it is possible to extend the lighting time of each lighting load.

FIG. 5 is a flowchart called PAD[ ] for explaining the operation of the control unit 3 in this embodiment. receive. When this interrupt occurs, the effects, which are the illumination states reproduced in step m1, are read out repeatedly from numbers 1 to 4. For each reproduction effect number 1, it is determined in step m2 whether the effect is being reproduced. If the effect is not playing, step m
1 and move on to the next playback effect number i. When the effect is being reproduced in step m2, the process moves to step m3, and the process is repeated until the channel number k changes from 1 to the maximum channel number CHm a X. For each channel number k, in step m4, it is determined whether the previously read dimming level Lki exceeds a certain value, for example zero. If the level does not exceed a certain level, processing A, which is normal processing, is performed in step m5. The contents of process A are shown in FIG. 6 and will be explained later. In step m4, if the previous dimming level Lki exceeds a certain level, this means that the corresponding lighting load is being lit, and the process moves to step m6. In step m6, the step length adjustment wheels 6a to 6d, which are the step length adjustment means 6,
It is determined whether the step length adjustment value XV has been adjusted. When the value of W is zero, Stella 7 m
Proceed to step 7, and process A is performed in the same way as step m5! L. When it is determined in step rn6 that W is greater than zero and that the step length adjustment wheels 6a to 6d have been operated, in step m8, the playback effect number i
A variable for each channel to calculate the step length of
The value of 5Cki whose initial value is zero is evaluated, and step m
Move on to 9. In step m9, the variable 5Cki is
It is determined whether it is greater than or equal to the sum of S Cirna x, which is the maximum value when calculating the length of one step of reproduction effect number i, and the step length adjustment value W.

As a result of this judgment, if it is larger than the sum, SCJ<i and ST k i
and is returned to the value when W is zero. When the processing related to step m4 is thus completed, the process moves to step mll. In step m11, playback effect number i
Channel number k, step number STk from the data set to realize effect control assigned to
The dimming level corresponding to i is extracted and output as Lki. In this way, when the repetitive operation for the channel number k in step m3 is completed and the repetitive operation for the playback effect number i in step m1 is completed, the interrupt processing in the control section 3 ends.

FIG. 5 is a PAD diagram for explaining the contents of the process shown as process A in FIG. When processing A starts, the value of variable 5Ckj is increased in step mal,
Move to step ma2. In step ma2, the value of variable 5Cki is compared with its maximum value to determine whether one step time has been completed. When one step time is completed, the process moves to step ma3. step ma
3, 5Cki is reinitialized to zero and the variable ST
The value of k i is increased. Thereafter, in step ma4, it is determined whether the value of 5Tki exceeds its maximum value. If the maximum value is exceeded, step ma
In step 5, reinitialize STk i with 1 and perform step 1
When processing A is ended in this way, processing A is a subroutine, so reading 5 returns to the original processing step.

In the above effect reproduction, an example of effect control is shown in which lighting loads of channels 1 to 4 are repeatedly turned on. Of course, by changing the data for reproducing effect control, various effect controls can be realized. for example,
By setting data for effect control so that each channel can be lit in an order as irregular as possible, it is possible to create an effect that looks like a burning flame. Furthermore, as in this embodiment, by using the step time adjustment foils 5a to 5d and the step length adjustment foils 6a to 6d,
While actually performing the dimming effect, effect control can be performed and adjustments can be made to achieve the desired effect.

Effects of the Invention As described above, according to the present invention, it is possible to individually set the lighting time of each lighting load and energize the lighting, so even when the predetermined unit time is set short, each lighting load The power can be energized for a sufficient time. Therefore, fast-changing illumination effects can be easily achieved.
