DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS. First, to describe the outline of the lighting system, the lighting system of this embodiment includes eight lighting groups GR1 to GR8. Each group GR1-8 is also referred to herein as a channel (CH), and consists of one or more lighting fixtures. Each of the groups GR1 to GR8 is dimming-controlled by one dimmer LL1 to LL8.

FIG. 2 is a control panel 3 of the dimming control device of the embodiment.
The structure of 0 is shown. The operation panel 30 has a NO. 1 to N
O. Eight key switches K1 to K8, a mode switch MDS, an up (UP) switch UPS, a stop (STOP) switch STS, and a down (DOWN) switch DNS are provided. 8 key switches K1
Reference numerals 8 to 8 serve also as a lighting scene selection switch corresponding to eight lighting scenes and a channel selection switch corresponding to eight lighting groups, and which mode of switch function is selected by the mode switch MDS. It depends on the mode. Here, in the reproduction mode described later, the key switches K1 to K8 function as illumination scene selection switches. Further, in the preparation mode described later, the key switches K1 to K8 function as channel selection switches.
It should be noted that, here, automatic switch-type push button switches are applied to all the switches.

The mode switch MDS switches and selects a reproduction mode (a mode for reproducing an illumination scene) and a preparation mode (a mode for storing an illumination scene). The up switch UPS, the down switch DNS, and the stop switch STS are for adjusting the dimming level in the preparation mode. When the up switch UPS is pressed once, the dimming level continuously increases, and the down switch DNS is set to 1
When the switch is pressed once, the dimming level continuously decreases, and when the stop switch STS is pressed, the dimming level is fixed at the position at that time. In addition, the up switch UPS,
The down switch DNS functions as an all-on switch and an all-off switch in the reproduction mode, respectively.

The control panel 30 is provided with various lamps in addition to these switches. As the lamps, scene lamps SL1 to SL8 indicating which selected lighting scene, channel (CH) lamps CL1 to CL8 indicating which selected channel (lighting group), and reproduction mode are selected. Reproduction mode lamp SML, preparation mode lamp PM indicating that preparation mode is selected
L, an up display lamp UL that indicates that the dimming level is rising, a down display lamp DL that indicates that the dimming level is falling, and all lights are on (lighted at a dimming level of 100%). All lighting indicator lamp UUL, which indicates that
An all-off display lamp DDL indicating that all lights are off (dimming level is 0%) is provided.

Further, as other lamps, charging level lamps PL1 to PL10 are provided. The charging level lamps PL1 to PL10 are arranged by vertically arranging ten lamps, and corresponding to the dimming level being set or set,
The lamps are lit in order from the bottom. The dimming level indicates "0%" when all are off, and the dimming level indicates "100%" when all are on. When the dimming level is 30%, the three lamps from the bottom are lit.

Next, the overall structure of the dimming control device will be described.
As shown in FIG. 3, the dimming control device of this embodiment is mainly composed of a microcomputer 50. As is well known, the microcomputer 50 has a CPU (not shown),
The microcomputer 50 includes a ROM (not shown), a RAM 51, and the like. The microcomputer 50 includes key switches K1 to K8, a mode switch MDS, and an up switch UP.
Operation signals for S, the stop switch STS, and the down switch DNS are input. As described above, the lighting system of this embodiment includes eight lighting groups GR1 to 8 and dimmers LL1 to LL provided for each of the groups GR1 to GR8. Is a Microcomputer
A dimming control signal is input from the controller 50. Accordingly, the dimmers LL1 to LL8 adjust the dimming states of the lighting devices of the groups GR1 to GR8 to the dimming level designated by the dimming control signal.

On the output side of the micro computer 50,
Scene lamps SL1 to SL8 via a drive circuit (not shown),
The charging level lamps PL1 to 10 and other lamps (reproduction mode lamp SML, charging mode lamp PML, up display lamp UL, all-on display lamp UUL, down-display lamp DL, all-off display lamp DDL) are connected,
The microcomputer 50 controls turning on and off of these lamps.

Next, the control operation of the microcomputer 50 for various operations will be described with reference to the flow charts of FIGS. In this embodiment, the microcomputer 50 executes the control program stored in the ROM so that the dimming level setting means 2 and the illumination shown in FIG. The scene storage unit 3, the illumination scene reproduction unit 4, and the reset unit 5 are realized. Microcomputer 5 by turning on the power
0 starts up, initializes at startup, and starts the routine of FIG. At the start-up stage, "playback mode" is selected as the mode. When the routine of FIG. 4 starts,
In the first step 101, two or more specific switches,
In this case, key switches K1, K4 and mode switch M
It is determined whether the three switches of the DS are turned on at the same time for a predetermined time (for example, 5 seconds). This condition judgment is
This is a judgment as to whether or not a request for resetting the RAM 51 has been made. The type and number of switches for setting the reset condition are not particularly limited, and the duration of the ON operation is also not particularly limited. However, it is preferable to set an operation that is not performed during normal operation as a condition in order to prevent malfunction.

When a reset request is made, that is, when the key switches K1 and K4 and the mode switch MDS are continuously turned on for a predetermined time, the process proceeds to step 102 to clear the data in the RAM 51. Then, step 1
At 03, the preparation level lamps PL1 to PL10 are blinked for a predetermined time (for example, 5 seconds) to indicate that the data in the RAM 51 has been cleared. This lamp is not turned on at the time of reproduction, and by blinking it, it can be sure that the reset operation is completed. On the other hand, if the reset request has not been issued, the determination in step 101 is NO, and step 102,
103 passes.

Next, as shown in FIG. 5, step 104
Proceed to ~ 108. In these steps 104 to 108, whether the up switch UPS is turned on, the down switch DNS is turned on, or the key switches K1 to 8 are turned on.
It is determined whether or not N has been given. In this process, the mode is the "reproduction mode", the up switch UPS functions as a full lighting switch, and the down switch DNS.
Functions as an all-off switch, and key switches K1 to
8 functions as a scene selection switch.

If the up switch UPS is turned on at this stage, the determination at step 104 becomes YES and the routine proceeds to step 105 where the control signals for all lighting are output to the dimmers LL1 to LL8. .. As a result, all the lighting groups GR1 to GR8 are turned on at the dimming level of 100%. If the down switch DNS is turned on, the determination in step 106 is YES and step 1
07, where the control signal for turning off all lights is sent to the dimmer L.
Output to L1-8. As a result, all the illumination groups GR1 to 8 are turned off.

If any of the key switches K1 to K8 is turned on, it means that the illumination scene of the registration number corresponding to the turned on key switch K1 to 8 is selected, and the process proceeds to step 109, Only the scene lamps SL1 to SL8 corresponding to the registration number of the selected illumination scene are turned on, and then, in step 110, a dimming control signal based on the stored data of the selected illumination scene is sent to each dimmer L.
Output to L1-8. As a result, the illumination scene stored in the selected registration number is reproduced. After the processing of steps 105 and 107, and when the determination of step 108 is NO, the process returns to the start step.

After the processing of step 110, step 11
In step 1, it is determined whether the mode switch MDS is turned on. If the mode switch MDS is not turned on, the process returns to the start step. The above is a loop of the reproduction operation, and unless the mode switch MDS is turned on to switch the mode from the “reproduction mode” to the “preparation mode”, the above processing operation is repeated.

At this stage, the mode switch MDS is turned on.
By switching the mode to "preparation mode",
If a request is made to load a new lighting scene into the lighting scene registration number currently selected in step 108, the judgment in step 111 becomes YES and step 1
12, proceed to turn on the preparation mode lamp PML,
At step 113, the reproduction mode lamp SML is turned off,
Go to step 114.

As shown in FIG. 6, this step 114 waits for any of the key switches K1 to K8 to be turned on. In other words, at this stage, the registration number for preparing the lighting scene has been decided, and it waits for the next request for which lighting group (channel) to adjust the dimming level. Here, in the preparation mode, the key switches K1 to K8 function as channel selection switches. Therefore, if any of the key switches K1 to K8 is turned on at this stage, a channel, that is, a group, whose dimming level is to be adjusted can be selected.

When any of the key switches K1 to K8 is turned on to select a channel, the determination at step 114 is Y.
It becomes ES and proceeds to step 115, where the channel (CH) lamp CL1 corresponding to the channel selected here is
8 is turned on, and in step 116, the current dimming level of the selected channel (this is stored in the RAM 51 as one of the data constituting the illumination scene) is adjusted to the preparation level lamps PL1 to PL1. Display by 10. Then, the process proceeds to step 117.

In step 117, it is determined whether or not the dimming level has been changed. If the up switch UPS is turned on to change the level, the process proceeds to step 118 to increase the dimming level by a predetermined minute amount, and then step 1
The dimming level is set at 19 with the preparation level lamps PL1 to PL10
Then, in step 120, the dimming control signals of the same level are output to the dimmers LL1 to LL8 to change the brightness of the corresponding channels (groups GR1 to GR8). Dimming level becomes 100% or stop switch STS is ON
Until this is done, the operations of steps 118 to 120 are repeated (steps 121 and 122) to gradually raise the dimming level. When the dimming level reaches 100% or the stop switch STS is turned on, the process proceeds to step 130.

On the other hand, when the down switch DNS is turned on, the routine proceeds to step 123, where the dimming level is lowered by a predetermined minute amount, and at step 124 the dimming level is displayed by the preparation level lamps PL1 to PL10, and at step 125. Then, the same level of dimming control signal is output to the dimmers LL1 to LL8 to change the brightness of the corresponding channel (group GR1 to GR8). Step 12 until the dimming level becomes 0% or the stop switch STS is turned on.
The operations of 3 to 125 are repeated (steps 126 and 12).
7) Then gradually lower the dimming level. Then, the dimming level becomes 0% or the stop switch STS
If is turned on, the process proceeds to step 130. Also,
If the operation of changing the dimming level is not performed (if it is not performed for a certain period of time), the determination in step 117 becomes NO and the process proceeds to step 130.

As shown in FIG. 7, in step 130,
It is determined whether or not the mode switch MDS is turned on. Unless the mode switch MDS is turned on, the process returns to the above step 114 and waits for the next channel selection. When the mode switch MDS is turned on, the determination in step 130 is YES and the process proceeds to step 131, where the combination of the dimming level of each channel is stored in the RAM 51 as the content of the illumination scene of the selected registration number. Then, the process returns to the start step.

Next, the preparation operation will be described step by step, focusing on the contents of the operation. (1) First, press the key switch K1-8 of the lighting scene number to be charged. (2) Scene lamp SL1 of the lighting scene number

(5) Press the key switches K1 to K8 of the channel for which you want to prepare (change) the light. (6) Channel lamp C of the pressed channel number
L1 to 8 light up. (7) The preparation level lamps PL1 to PL10 are turned on at the stored dimming setting level. (8) Up switch UPS or down switch DN
When any one of S is pressed, the output of the channel becomes gradually brighter with the up switch UPS (it stops when reaching 100%), and the up display lamp UL blinks. If the down switch DNS, it becomes dark gradually (stops when it reaches 0%), and the down display lamp DL blinks. At the same time, the charging level lamps PL1 to PL10 change at the same level. (9) Press the stop switch STS to stop at the brightness at that time. (10) The above (5) to (9) are similarly performed for other channels to be charged. (11) When the setting of the brightness of all the channels in the same scene is completed, press the mode switch MDS again. (12) As a result, the mode is switched to the “reproduction mode”, and the setting value (light control setting level) of the light performed in the above (10) is stored. If the operation of (11) is not performed, the brightness level is not stored, and the stored storage status of the brightness before the setting of the brightness is not changed. (13) For other scenes you want to prepare, (1) ~
Repeat (12).

Next, the operation for turning on and off the light will be described. First, when reproducing the light, the operations are performed in the following order. (1) When the mode switch MDS is pressed to enter the reproduction mode, the reproduction mode lamp SML lights up. (2) Key switch K1 for the scene number you want to play
