Main controller 4 includes switching elements 5 and 6 that are inserted into AC power supply 1 so as to form a closed loop with lighting loads 2 and 3, respectively. The switching elements 5 and 6 perform phase control corresponding to the dimming level in the range of 0 to 100% with respect to the illumination loads 2 and 3, or perform blinking control that alternately switches the extinguished state and the lit state. .. The driving of the switching elements 5 and 6 is performed by the control means 7. The control means 7 includes a microcomputer, and the lighting load 2,
A plurality of scenes are stored with one illumination pattern based on the combination of the dimming level of 3 and the blinking state as one scene, and the switching elements 5 and 6 are controlled so as to reproduce the selected scene. The control means 7 is connected with an input means 12 such as an all-off switch 8, a blinking switch or a dimming switch 9, and scene switches 10 and 11. When the all-off switch 8 is operated, power is not applied to all the lighting loads 2 and 3, and the lighting loads 2 and 3 are turned off. Either scene switch 10 or 11
Select one and operate it to reproduce the corresponding scene. The blinking or dimming switch 9 is provided for each lighting load circuit, and the corresponding lighting load can be controlled individually in the selected state of one scene. In this way, when all the lighting loads 2 and 3 are individually controlled and the all-off switch 8 is operated, the power to all the lighting loads 2 and 3 is not energized, and all the lighting loads are turned off. It becomes a state. When one scene is selected by operating the scene switches 10 and 11, a light emitting diode (hereinafter abbreviated as "LED") provided adjacent to the scene selection switches 10 and 11 on the operation panel of the main operation device 4. , One of the scene selection display LEDs 13 and 14 is lit. The control means 7 controls the display means 15 including the scene selection display light emitting diodes 13 and 14 in response to the input from the input means 12, and at the same time, an interface circuit (hereinafter abbreviated as “I / F”) 16 is provided. A signal is transmitted via a signal line 18 to a remote controller operating device 17 provided in a room different from the room in which the lighting loads 2 and 3 are provided.

The remote controller operating device 17 is connected to the signal line 18 via an I / F 19. To the control means 20 of the remote control operating device 17, an input means 24 including an all-off switch 21, scene switches 22 and 23, and a display means 27 including scene selection display LEDs 25 and 26 are connected. The operations of the input unit 24 and the display unit 27 are performed in the same manner as the main control device 4. The operation result by the input means 24 is sent from the remote controller operating device 17 to the main control device 4 via the signal line 18, and the lighting loads 2 and 3 are controlled and the display means 15 displays.

FIG. 6 is a state transition diagram for explaining the operation of the conventional lighting control device shown in FIG. When neither of the lighting loads 2 and 3 is energized, all the lights are turned off, and the scene selection display LEDs 13, 14; 25,
All of 26 are not lit and all display is turned off. One of the scene switches 10, 11; 2 when all lights are off
When 2, 23 are operated, the scene is turned on and the scene selection display LEDs 13, 1 corresponding to the selected scene are displayed.
4; 25, 26, scene selection display is performed. When the flashing switch or the dimming switch 9 for each circuit is operated in the scene lighting state, the scene correction state is set. From the scene correction state, the scene switches 10, 11; 22, 23
When is operated, the scene lights up again. When all the extinguishing switches 8 and 21 are operated in such a scene selection display state, the all extinguishing state is set.

As described above, in the conventional lighting control device, in order to turn on the lighting loads 2 and 3, it is necessary to operate the scene switches 10, 11; 22 and 23 to select one scene. Since one scene is composed of lighting patterns for a plurality of lighting loads 2 and 3,
It cannot meet the needs of turning on only the desired lighting loads 2 and 3. Although it is possible to set only a specific lighting load to be turned on in one scene, generally, the number of scenes that can be set is limited, and the lighting of individual lighting loads 2 and 3 can be set for each scene. However, the number of scenes in which the combination of the lighting loads 2 and 3 can be designated decreases.

Further, even if the main control device 4 is constructed so that the individual lighting loads 2 and 3 can be turned on, such a lighting state causes the remote control operation device 17 to operate.
When it is not possible to display in the remote control operation device 17
Since the lighting states of the lighting loads 2 and 3 cannot be confirmed, there is a risk of forgetting to turn off the lights.

The control means 57 includes an all-off switch 58, a blinking switch or a dimming switch 59 provided corresponding to each of the lighting load circuits 52, 55; 53, 56, and a scene switch 60 for selecting one of a plurality of scenes. , 61 are connected to the input means 62. When the all-off switch 58 is operated, the power supply to all the lighting loads 52 and 53 is stopped, and the lighting loads 52 and 53 are turned off. Each scene stored in the memory of the control means 57 is
It is selected by operating one of the scene switches 60 and 61. The control means 57 reads the stored contents of the memory corresponding to the selected scene and controls the switching elements 55 and 56. A display means 65 including scene selection display LEDs 63 and 64 is connected to the control means 57. When one scene is selected, the scene display LEDs 63, 64 corresponding to the selected scene
Lights up. The scene switches 60, 61 and the scene selection display LEDs 63, 64 are arranged at corresponding positions on the operation panel of the main controller 54. The control state of the main control device 54 is such that the lighting loads 52 and 53 are provided from the control means 57 via the I / F 66, and the remote control operation device 67 is installed in a room different from the room in which the main control device 54 is installed. Be transmitted to.

The remote controller 67 is a main controller 54.
Are connected via a signal line 68. The signal line 68 transmits an electric signal bidirectionally. An I / F 69 is provided on the remote controller operating device 67 side of the signal line 68, and is further connected to the control means 70. The control means 70 includes a microcomputer or the like, receives a signal transmitted from the main control device 54 via the signal line 68, and performs processing in accordance with the content represented by the signal. It also sends a signal to main controller 54.

The control means 70 includes an all-off switch 71,
Input means 74 including scene switches 72 and 73 and display means 77 including scene selection display LEDs 75 and 76 are connected. It should be noted that the temporary lighting LED 78 is further connected to the control means 70.

When one scene is selected by the control means 57 of the main controller 54, the control means 70 displays the scene by the display means 77. Scene switch 7
When one of 2, 73 is operated, the scene is displayed by the scene selection display LEDs 75, 76,
A signal representing the selected scene is transmitted to main controller 54 via signal line 68. In the main controller 54, the scene represented by the received signal is selected and displayed by the scene selection display LEDs 63 and 64.

As described above, in both main controller 54 and remote controller 67, one scene can be selected and all lights can be turned off. The fact that all lights are off means that the scene selection display LED 63,
Since all of 64; 75 and 76 are in the off state, it can be known from either main controller 54 or remote controller 67. When the main controller 54 is installed in the room where the lighting loads 52 and 53 are installed,
Of course, it is possible to directly confirm the extinguished state of the lighting loads 52 and 53.

When the lighting loads 52 and 53 are all in the off state, by operating the blinking switch or the dimming switch 59 of the main controller 54, the corresponding lighting loads 52 and 53 can be turned on. The blinking switch or the dimming switch 59 is provided for each of the lighting loads 52 and 53,
Originally, it is used to correct the dimming level or blinking state of the corresponding lighting load in each selected scene. The dimming level is corrected by operating the switch 59 to further increase or decrease the set dimming level. Such a lighting state of the lighting loads 52, 54 cannot be displayed by the scene selection display LEDs 63, 64; 75, 76 because the scene is not selected. The main controller 54 is connected to the lighting loads 52, 53.
If it is installed in the room in which is installed, the lighting state of the lighting loads 52 and 53 can be directly confirmed on the main controller 54 side. When the remote control operating device 67 is installed in another room, it is not possible to directly check the lighting states of the lighting loads 52 and 53, and therefore the remote control operating device 67 is provided with the temporary lighting LED 78. When the lighting loads 52 and 53 are in the lighting state, the control means 70 of the remote controller operating device 67 lights the temporary lighting display LED 78 in accordance with a signal via the signal line 68.

FIG. 2 is a state transition diagram for explaining the operation of the embodiment shown in FIG. All lighting loads 52, 53
When no power is applied to the power source, all lights are off. When the blinking switch or the dimming switch 59 corresponding to the lighting loads 52 and 53 of the main controller 54 is operated,
The lighting loads 52 and 53 corresponding to the operation are temporarily turned on. Switch off all lights 58, 71
When is operated, all lights are turned off again. In the all-off state and the temporarily-on state, the scene selection display LEDs 63, 6
4; 75 and 76 are not turned on, and all are turned off. When any one of the scene switches 60, 61; 72, 73 is operated in the state where all lights are off, the selected scene is reproduced and the scene is turned on. In this state,
Flashing switch or dimming switch 6 for each lighting load circuit

When the scene switches 60, 61; 72, 73 are operated in the scene correction state, the scene corresponding to the operation is reproduced and the scene is turned on. In such a scene lighting state and a scene correction state, the scene selection display LED 6 corresponds to the selected scene.
3, 64; 75, 76, scene selection display is performed. When the all-off switches 58 and 71 are operated from the state where the scene selection display is being performed, the all-off switch returns to the all-off state.

FIG. 3 is a flow chart for explaining the operation of main controller 54 in the embodiment shown in FIG. From step a1 to step a2, it is determined whether or not all lights are off. If it is in the all-off state, it is determined in step a3 whether it is in the temporarily lit state. If the light is on temporarily, step a4
Then, the fact that it is in the temporary lighting state is transmitted to the remote control operating device 67. When step a4 is completed, when it is determined in step a3 that it is not in the temporarily lit state, or when it is determined in step a2 that it is not in the all-off state, the process proceeds to step a5. Step a5
At, it is determined whether or not there is a state input by operating the scene switch, and the process waits until there is an input. Next, in step a6, the selected scene state is output from the memory, and the lighting load circuit 5 is responsive to the stored contents.
2, 55; 53, 56 are controlled respectively. The state of the selected scene is transmitted to the remote controller operating device 67. Next, the process returns from step a7 to step a1, and the operations from step a1 to step a7 are repeated.

FIG. 4 is a flow chart for explaining the operation of the temporary lighting display of the remote controller operating device 67 in the embodiment shown in FIG. In step b1, main controller 54 is operated in step a4 of the flowchart of FIG.
The signal indicating the temporary lighting state transmitted from the device is received.
Next, in step b2, the LED 78 for temporary lighting is displayed.
Is turned on, and a temporary lighting display is performed. Next, at step b3, it is judged whether or not there is a switch input of the input means 74. When there is no switch input, the process returns to step b2. In step b3, when there is a switch input, in step b4, the display on the display unit 77 is displayed corresponding to the input switch, and the signal line 6
A signal is transmitted via 8 to the main controller. Then, in step b5, the process ends.

In the above embodiment, the remote control operating device 67 is provided with the temporary lighting LED 78 to display the temporary lighting state. However, by displaying the scene selection displaying LEDs 75 and 76 in a blinking manner, other It goes without saying that the temporary lighting state can be displayed by the means. Further, although the main controller 57 and the remote controller 67 are provided with the all-off switches 58 and 71, the all-off state is assigned to one scene, and that scene is switched to the scene switches 60, 61;
Of course, it is possible to realize the all-off state by selecting 3 and working.

In the lighting load circuits 52, 55; 53, 56, amphoteric three-terminal thyristors are used as the switching elements 55, 56, but it goes without saying that other semiconductor switching elements such as transistors may be used. is there. Further, it goes without saying that blinking control may be performed by a relay or the like. Although the dimming level for each of the lighting loads 52 and 53 for one scene is corrected and set by the dimming switch 59, it may be set by using a preset fader using a variable resistor or the like. Of course.

Although the main controller 54 and the remote controller 67 are connected by a signal line 68 in a wired manner, it goes without saying that they may be connected by radio such as radio waves or light. Further, it goes without saying that a high frequency signal may be superimposed on the line of the AC power supply 51 to transmit the signal. Furthermore, it goes without saying that signals may be transmitted using optical fibers or the like. Main controller 5
The signal transmission between the remote controller 4 and the remote control operating device 67 is performed when the input means 62 and 74 are operated, so that it is not necessary to transmit a large amount of information at high speed, and the signal line 68 is provided. It's easy.

[0024]

As described above, according to the present invention, since the main controller is provided with the lighting means, it is possible to individually light the lighting load circuits from the all-off state. Therefore,
By installing the main control device in the room where the lighting load of the lighting load circuit is provided, it is possible to turn on the lighting load individually and make it temporarily bright even if the room is completely off. .. Such a need occurs frequently in daily life. For example, this is for preparing or rearing in a hall or a stage where light control is performed.

Since the remote control device can be installed separately from the main control device, it can be installed in a room different from the room in which the lighting load is installed. Since the lighting control means is provided in the remote control device, it is easy to know that the lighting load circuit is in the lighting state even if it is not possible to directly confirm that the lighting load circuit is in the lighting state. In this way, in the remote control device that can be provided separately, the lighting state of the lighting load circuit can be monitored and confirmed, so that it is possible to prevent forgetting to turn it off when going out or going to bed.
