Description

Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to a controller,
The present invention relates to a lighting control system including a lighting fixture and a wall switch.

[0002]

2. Description of the Related Art Conventionally, this type of lighting control system has been
As shown in FIG. 2, the controller 1 is arranged on the ceiling A, and the lighting fixtures 2 and 3 having the built-in lighting device are arranged.
The wall switch 4 is placed on the wall B, and the input power line 5 from the outside
To the wall switch 4, the power line 6 from the wall switch 4 to the controller 1 and the lighting fixture 2, the power line 7 from the lighting fixture 2 to the lighting fixture 3, and from the controller 1 to each lighting device. The dimming signal line 8 is wired to the second and third wirings.

[0003]

However, in this conventional configuration, it is necessary to route the input power supply line to the wall side,
Further, since the power line is to be laid from the wall side to the back of the ceiling, and the power line cannot be directly routed to the back of the ceiling, the construction is troublesome. Further, the wall switch 4 directly controls the power supply to the controller 1 and the lighting fixtures 2 and 3 to be turned on and off, and the controller 1 sends a dimming signal to the lighting fixtures 2 and 3 when the power is turned on by the wall switch 4. Since the light is transmitted and the light control is performed, the control of the lighting fixtures 2 and 3 by the controller 1 and the on / off control of the wall switch 4 interfere with each other, and, for example, the light control of the lighting fixtures 2 and 3 is performed by the controller 1. Then, if the lighting devices 2 and 3 are once turned off by the wall switch 4 and then turned on, the immediately preceding dimming state is not immediately reproduced, and there is a problem that the lighting state is switched to the dimming state once the lighting state is 100%. It was

Therefore, according to the present invention, it is easy to install the power line, and when the lamp is turned off in the dimming state and then turned on, the immediately preceding dimming state can be reproduced, and the conventional system can be easily constructed. A lighting control system that can also be used is provided.

[0005]

Means for Solving the Problems The present invention incorporates a controller, which is arranged on the ceiling and which sends a lighting control signal, and a lighting device, which is arranged on the ceiling and controls the brightness by a lighting control signal from the controller. It is equipped with a lighting fixture and a wall switch that is placed on the wall and turns on / off a signal line connected to the controller. The wall switch and the controller are connected only by the signal line, and the controller and the lighting fixture each have an input power source. The line is wired, and the lighting device is in a lighting control system that controls extinguishment by a signal output from the controller when the controller detects the off state of the wall switch.

[0006]

Embodiments of the present invention will be described below.
A description will be given with reference to the drawings. As shown in FIG. 1, a controller 11 is arranged on a ceiling A, lighting fixtures 12 and 13 having a built-in lighting device are arranged, and a wall switch 14 is arranged on a wall B.
Are arranged. The wall switch 14 turns on / off the signal line 15 connected to the controller 11, and the wall switch 14 and the controller 11 are connected only by the signal line 15. The controller 11
Input power lines 16, 17, and 18 from the outside are wired to the lighting fixtures 12 and 13, respectively. From the controller 11 to the respective lighting devices 12 and 13, a dimming signal line 19
Is wired.

In such a configuration, the controller 11 detects whether the wall switch 14 is turned on or off by the signal line 15 thereof. Then, in a state where the ON state of the wall switch 14 is detected, a dimming signal is transmitted to each of the lighting devices 12 and 13 to control the dimming lighting of each lighting device. Further, when the controller 11 detects that the wall switch 14 is turned off, it controls the lighting devices of the respective lighting devices 12 and 13 to be turned off.

In this way, the controller 11 detects the on / off state of the signal line 15 by the wall switch 14, and controls the lighting devices of the respective lighting devices 12 and 13 to be turned on, dimmed, and turned off. The controller 11 can reliably control the lighting devices of the lighting devices 12 and 13. Therefore, when the controller 11 turns off the lighting device in a dimming state and then turns it on again, the controller 1
1 makes it possible to immediately reproduce the lighting device in the immediately previous dimming state.

Further, it is not necessary to route the input power supply line to the wall side, and the input power supply line can be directly wired to the back of the ceiling and connected to the controller 11 and each of the lighting devices 12 and 13, thus facilitating the construction. Is.

Further, this system can be easily constructed by using the power line from the wall switch to the controller as it is in the conventional system shown in FIG. 2 as an ON / OFF signal line. That is, the conventional system can be easily used, and the construction is easy in this respect as well.

If a light sensor is arranged in the controller 11, it becomes possible to automatically turn on or off the lighting devices 12 and 13 or control the dimming according to the ambient brightness. Further, if a human sensor is arranged in the controller 11, it is possible to detect whether or not there is a person in the room by this sensor and automatically turn on or off the lighting devices 12 and 13 or perform dimming control. become. By arranging the various sensors of the controller 11 in this way, each lighting device 1
It is possible to widely turn on and off the lights 2 and 13 or perform dimming control.

[0012]

As described above in detail, according to the present invention,
A lighting control system that is easy to install the power line, and can immediately reproduce the previous dimming state when the light is turned off in the dimming state and then turned on, and the conventional system can be easily used. Can be provided.
