By the way, for example, in a lighting system installed in a wide space such as a classroom or a conference room, a plurality of controllers for executing dimming control may be provided for one lighting fixture. In such a lighting system, a dimming signal is transmitted from each controller to control the dimming of the luminaire.

Here, in the case where the dimming signal is transmitted from the controller to the lighting equipment by wireless communication, the dimming signal is transmitted from the controller at predetermined time intervals in order to ensure the communication reliability of the dimming signal. .. Therefore, since the dimming signal is constantly transmitted from the controller to the luminaire, only one controller is provided for one luminaire. That is, when a dimming signal is transmitted from a controller to a luminaire by wireless communication, it is difficult to provide a plurality of controllers for one luminaire.

Therefore, an object of the present invention is to provide a lighting system capable of controlling a lighting fixture from each controller in a lighting system in which a dimming signal is transmitted from a plurality of controllers to the lighting fixture by wireless communication.

In order to achieve the above object, the lighting system according to the embodiment of the present invention includes a lighting fixture and a plurality of controllers provided for controlling dimming of the lighting fixture. The controller wirelessly communicates with an operation unit that receives a dimming setting from a user, a control unit that generates a dimming signal including a dimming setting received from the user, and an update time that receives the dimming setting. A communication unit that transmits a dimming signal generated by the control unit at predetermined time intervals is provided. The luminaire has its own light source according to a communication unit that receives dimming signals transmitted from the plurality of controllers, and a dimming setting included in the dimming signal having the latest update time among the received dimming signals. It is provided with a control unit for controlling.

The control unit 22 is composed of, for example, a microcomputer including a CPU and a semiconductor memory. The control unit 22 controls the dimming of the light source 23 composed of an LED (Light Emitting Diode) or the like according to the dimming setting included in the received dimming signal.

Here, since the lighting system includes a plurality of controllers 1, the communication unit 21 receives a plurality of dimming signals within a predetermined time. Therefore, the control unit 22 includes a signal selection unit 25 that selects a dimming signal used for controlling the dimming of the light source 23 among the dimming signals input from the communication unit 21 within a predetermined time.

The signal selection unit 25 detects the update time included in the dimming signal input to the control unit 22. Then, the signal selection unit 25 selects the dimming signal having the latest update time among the dimming signals input to the control unit 22 within a predetermined time. The control unit 22 controls its own light source 23 according to the dimming setting included in the dimming signal selected by the signal selection unit 25.

-Operation of lighting system-

In step S12, the controller 1A generates the dimming signal CS1. Specifically, the controller 1A includes the dimming setting received by the operation unit 11, and includes the current time generated by the time unit 14, that is, the time when the dimming setting from the user is received as the update time. Generate CS1.

In step S13, the controller 1A transmits the dimming signal CS1 to the luminaire 2. Specifically, the communication unit 13 of the controller 1A transmits the dimming signal CS1 generated by the control unit 12 to the luminaire 2 at predetermined time intervals by wireless communication.

In steps S21 to S23, similarly to the controller 1A, the controller 1B generates a dimming signal CS2 including the dimming setting from the user and includes the time when the dimming setting is received as the update time, and wirelessly communicates with the controller 1B. It is transmitted to the lighting fixture 2 at predetermined time intervals.

In steps S31 and S32, the luminaire 2 receives the dimming signals CS1 and CS2 by wireless communication. Specifically, the communication unit 21 of the lighting fixture 2 receives the dimming signal CS1 transmitted from the communication unit 13 of the controller 1A and the dimming signal CS2 transmitted from the communication unit 13 of the controller 1B. The communication unit 21 of the luminaire 2 outputs dimming signals CS1 and CS2 to the control unit 22.

In step S33, the signal selection unit 25 (control unit 22) of the lighting fixture 2 selects the dimming signal. Specifically, the signal selection unit 25 detects the update time included in the dimming signals CS1 and CS2, and selects a dimming signal having a new update time from the dimming signals CS1 and CS2.

In step S34, the luminaire 2 controls the dimming of the light source 23 according to the dimming setting included in the dimming signal selected by the signal selection unit 25.

With the above configuration, each controller 1 controls to generate a dimming signal including an operation unit 11 that receives a dimming setting from the user, a dimming setting received from the user, and an update time that receives the dimming setting. The unit 12 includes a communication unit 13 that transmits a dimming signal generated by the control unit 12 at predetermined time intervals by wireless communication. The luminaire 2 has its own communication unit 21 that receives the dimming signal transmitted from each controller 1, and the lighting fixture 2 according to the dimming setting included in the dimming signal having the latest update time among the received dimming signals. It includes a control unit 22 that controls the light source 23. That is, when the user sets the dimming setting for the controller, the controller generates a dimming signal including the time when the user's dimming setting is received as the update time and transmits it to the lighting equipment. Then, the luminaire controls the dimming of the light source according to the dimming signal including the latest update time among the received dimming signals, that is, the dimming signal having the latest dimming time when the user's dimming setting is received. As a result, the user can control the dimming of the luminaire by setting the dimming setting for any one of the plurality of controllers. Therefore, in a lighting system in which a dimming signal is transmitted from a plurality of controllers to the luminaire by wireless communication, the luminaire can be controlled from each controller.

(Second Embodiment)
FIG. 3 is a block diagram of the lighting system according to the second embodiment. The lighting system according to the present embodiment includes a plurality of controllers 1, a controller 1C, and a lighting fixture 2A. Since the configuration of the controller 1 is the same as that of the first embodiment, the description thereof will be omitted. In FIG. 3, the controller 1C is provided with the signal selection unit 15, while the luminaire 2A is not provided with the signal selection unit 25.

Specifically, the communication unit 13 of the controller 1C receives the dimming signal from the controller 1 by wireless communication.

Further, the signal selection unit 15 of the controller 1C has the latest update time among the dimming signal generated by itself (control unit 12 of the controller 1C) and the dimming signal received from the controller 1 by wireless communication. Select an optical signal. Specifically, the signal selection unit 15 detects the update time included in the dimming signal generated by itself and the dimming signal received by wireless communication, and selects the dimming signal having the latest update time. The communication unit 13 of the controller 1C transmits the dimming signal selected by the signal selection unit 15 to the luminaire 2A by wireless communication or wired communication.

The communication unit 21 of the luminaire 2A receives the dimming signal from the communication unit 13 of the controller 1C. The control unit 22 of the luminaire 2A controls the dimming of the light source 23 according to the dimming setting included in the received dimming signal.

With the above configuration, the same effect as that of the first embodiment can be obtained.

Further, in this lighting system, the lighting fixture 2A is not provided with the signal selection unit 25. That is, this lighting system can be applied to existing lighting fixtures.

In the present embodiment, the controller 1C is provided with the operation unit 11 and the time unit 14, but the controller 1C may not be provided with the operation unit 11 and the time unit 14.

(Other embodiments)
As described above, embodiments have been described as examples of the techniques disclosed in this application. However, the technique in the present disclosure is not limited to this, and can be applied to embodiments in which changes, replacements, additions, omissions, etc. are appropriately made.

In the above embodiment, the operation unit 11 of the controllers 1 and 1C does not control the luminaires 2 and 2A according to the dimming settings accepted by the other controllers, but the luminaires 2 and 2A according to the dimming settings accepted by themselves. You may accept the setting of the forced mode to control. In this case, when the operation unit 11 accepts the forced mode setting, the control unit 12 sends a dimming signal including time data (forced mode data) indicating that the forced mode setting is accepted instead of the update time. Generate. Here, for example, it is assumed that "9999/99/99/99/99/99" (year / month / day / hour / minute / second) is used as the forced mode data. Then, the signal selection unit 15 of the controller 1C and the signal selection unit 25 of the lighting fixture 2 select the dimming signal when the dimming signal including the forced mode data is included in the received dimming signal. ..

For example, when the operation unit 11 receives a predetermined dimming setting (for example, the dimming rate is 100%) from the user, the controllers 1 and 1C determine that the forced mode setting has been accepted, and the update time. Instead, a dimming signal including forced mode data, that is, "9999/99/99/99/99/99" is generated. Then, the signal selection unit 15 of the controller 1C and the signal selection unit 25 of the lighting fixture 2 select the dimming signal including the forced mode data. As a result, the luminaire can be controlled by only one of the plurality of controllers. The operation unit 11 of the controllers 1 and 1C may be provided with a button or the like for setting the forced mode.

Further, in the above embodiment, the controllers 1 and 1C may have a motion sensor. Specifically, the controllers 1 and 1C may generate a dimming signal including an update time based on the detection timing of the motion sensor. For example, the controllers 1 and 1C may generate a dimming signal whose update time is the timing when the motion sensor detects the human body or the timing when the detected human body is no longer detected.

Further, in the above embodiment, when the lighting fixture 2 receives the dimming signal from the controller 1, it may notify the controller 1 that the dimming signal has been received by wireless communication. Further, when the controller 1C and the luminaire 2A receive the dimming signal from the controllers 1 and 1C, respectively, they may notify the controllers 1 and 1C that the dimming signal has been received by wireless communication. That is, in the above embodiment, the two-way communication may be configured so that the controllers can communicate with each other and the controller and the luminaire can communicate with each other.

Further, in the above embodiment, there may be a plurality of controllers 1, 1C and a plurality of lighting fixtures 2.

Since the dimming control of the lighting fixture can be executed by a plurality of controllers, the present invention can be applied to a lighting system provided with a plurality of controllers used for dimming control of the lighting fixture, for example, in a large classroom or a conference room.
