Description

Detailed Description of the Invention

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lighting device, and more particularly to a lighting device suitable for large-scale facilities and buildings.

2. Description of the Related Art Conventionally, there has been provided a lighting device for collectively controlling a plurality of lighting fixtures. FIG. 10 is a schematic configuration diagram showing a lighting device according to a conventional example. This lighting device
The base unit 1 and a base unit terminal 8 for operating the base unit 1 are provided, and the base unit 1 is connected with the handset 2, the motion sensor 5, and the brightness sensor 6 via a signal line L. There is. A plurality of lighting fixtures 3 are connected to each of the slaves 2.
Further, the operation for the master device 1 can be performed from the master device 1 main body or the master device terminal 8. The human sensor 5 and the brightness sensor 6 transmit their respective detection information to the master device 1, and tell the slave device 2 to perform a predetermined control on the lighting fixture 3 based on the detection information. Send a control signal.
The slave unit 2 transmits a dimming signal to a plurality of lighting fixtures 3 connected to itself so as to illuminate at a dimming level determined by the control signal received from the master unit 1, and collectively adjusts the dimming signal. By lighting or turning on / off the power according to the control signal received from the master unit 1, the plurality of lighting fixtures 3 connected to itself are made to blink at once. In addition, lighting equipment 3
It is also possible to forcibly change the control of (1) from the base unit 1 or the base unit terminal 8, and it is possible to arbitrarily turn on / off the light. However, in the above-described lighting device, the forcible control of the lighting fixture 3 can be performed only from the main unit 1 main unit or the main unit terminal 8, and therefore, when a large-scale system or a highly convenient system construction is aimed, the main unit terminal There is a problem that it is necessary to increase the number of eight, which leads to a complicated system and wiring. In addition, when trying to group or collectively control the lighting fixtures 3, it is necessary to operate the parent device 1 each time, and the responsiveness is poor. In addition, a different conventional example is shown in FIG.
And FIG. 12 will be described. FIG. 11 is a block diagram showing the slave unit 2, and 29 is a power supply unit which supplies power to the ballast 30 and the control unit 25. Ballast 30
The lighting device 3 such as a fluorescent lamp is turned on / off, and can be operated only by a signal from the control unit 25. Here, the control unit 25 of the child device 2 in the system shown in FIG.
Each has an ID (a to t in FIG. 12) and is uniquely sorted. As a result, the remote unit 2 can be operated by an external remote controller.
It is possible to group the. For example,
As shown in FIG. 12, a, b, c, e, f, g, i, j
• k can be grouped (region A) and m to t can be grouped (region B). Then, it is possible to perform control for each group. The control unit 25 receives signals from the motion sensor 5, the brightness sensor 6, and the signal receiving unit 21, and controls the ballast 30 by the signals. The signal receiving unit 21 receives the signals of the human sensor 5 and the brightness sensor 6 from the other child device 2 in the system, and also outputs the signals of the human sensor 5 and the brightness sensor 6 connected to itself. It transmits to the other handset 2 at a constant cycle. Regarding the signal transmission / reception, it is possible to give directionality, and it is possible to target all the slaves 2 in the system or only within the same group. Those settings are made by an external remote controller or the like. When the control unit 25 receives a signal from the human sensor 5 of its own or the human sensor 5 from another child device 2, the controller 25 normally turns on the lighting device 3 in the off state. The control unit 25 has a timer function, and stops the oscillation of the ballast 30 or turns off the power after counting for a certain period of time. However, if a signal from the motion sensor 5 or another slave unit 2 is received again while the timer is counting, the timer is reset. Further, when the control unit 25 receives the signal of the brightness sensor 6 from its own brightness sensor 6 or another slave unit 2, the control unit 25 converts the table data and the signal of the brightness sensor 6 set in advance in the control unit 25. Based on this, the luminaire 3 is dimmed to a predetermined brightness. Here, the brightness sensor 6 monitors the brightness of the lower surface of itself and sends a signal corresponding to the brightness to the control unit 25. However, in the above-described lighting device, since all the slaves 2 have individual IDs, it is possible to control from each slave 2 to all the specific slaves 2. Since the wiring becomes complicated and the traffic of the signal line increases, complicated control is required.

In the conventional lighting device, when performing collective control or group control for a plurality of slave units, it was necessary to issue a command from the master unit. However, it is expected that temporary all-off / all-lighting will be used relatively frequently, and it is inconvenient to operate the main unit installed at a distant position each time. In addition, even if the terminals of the parent device are provided in the required places, it is necessary to increase the number of terminals as the system becomes larger. Convenience can be secured by increasing the number of terminals of the base unit, but it will also coexist with the terminals of the handset units, resulting in a complicated system due to the proper use of terminals, system configuration, and increase in signal traffic.
Further, as a conventional example, there is one disclosed in Japanese Patent Laid-Open No. 154082/1992. It is composed of a main luminaire, a plurality of sub luminaires, and a transmitter for transmitting a remote control signal for controlling the luminaire. When the main luminaire receives the remote control signal from the transmitter, the main luminaire transmits the remote control signal to all the sub luminaires, and the sub luminaire receives the remote control signal from the transmitter. Is designed to transmit a remote control signal from the sub lighting fixture to the main lighting fixture, and to transmit a remote control signal from the main lighting fixture to all the sub lighting fixtures. Therefore, the remote control signal from the transmitter can be reliably transmitted to the sub lighting device via the main lighting device and the main lighting device. However, in the device disclosed in Japanese Patent Laid-Open No. 154082/1992, signals are transmitted wirelessly, so that it is necessary to dispose the main lighting equipment and the sub lighting equipment in close proximity to each other. In addition, the luminaires in a predetermined closed space are collectively controlled, and the group control cannot be performed. The present invention has been made in view of the above problems, and an object of the present invention is to provide a lighting device that has a simple configuration and can easily control a plurality of lighting fixtures. is there.

In order to solve the above problems, in the present invention, a master unit for transmitting a control signal for controlling a slave unit, a plurality of slave units, and each slave unit. A lighting device that is connected to a device and is controlled by a child device to which the device is connected, and a controller for controlling a child device that is associated with each of the child devices. Machine controls the lighting device connected to itself based on a control signal from the master unit, based on a control request signal that the master unit requests control of the other slave unit from the slave unit, A control signal is transmitted to the other child device. As a result, it is possible to temporarily control the master unit from the slave unit in the centralized control system, and it is possible to control the master unit from the slave unit without the terminal of the master unit, and with a simple system configuration. Moreover, a highly convenient lighting device can be realized.

BEST MODE FOR CARRYING OUT THE INVENTION (First Embodiment) An illumination device according to a first embodiment of the present invention will be described below with reference to FIGS.

Not something. The handset 2 receives a control signal from the base unit 1, a signal receiving unit 22 that sends a control request signal to the base unit 1, and a remote control signal receiving unit 23 that receives a signal from the remote control 4. And an information signal transmitting unit 24 that transmits information (for example, dimming ratio and address) of the slave unit 2 to the remote controller 4 as an information signal, and creates a dimming signal based on the received signal and Control unit 2 for creating
5, and a power switch unit 2 for turning on / off the power supply
6 and a dimming signal transmitting unit 27 that transmits a dimming signal for performing dimming control of the lighting fixture 3. Here, each slave unit 2 has an individual address. When the control signal from the base unit 1 is received by the signal receiving unit 21, the control unit 25 determines the dimming level and the lamp blinking state based on the content of the control signal, and the power switch unit 26 instructs the lighting fixture 3 to operate. In addition to supplying a predetermined power, the dimming signal transmitter 27 transmits a dimming signal for dimming the lighting fixture 3. In the present embodiment, if the control signal from the master unit 1 indicates that the lamp is on, the power switch unit 26 is turned on to supply power to the lighting fixture 3, and the control signal from the master unit 1 is sent to the lamp. If the light is off, the power switch unit 26 is turned off to cut off the power. Similarly, for example, if the control signal from the master unit 1 is turned on at a dimming ratio of 50%, the dimming signal transmitting unit 27 transmits a corresponding dimming signal to dimm the lighting fixture 3. In addition to the control of the lighting device 3 based on the control signal from the master device 1, the slave device 2 can also control the lighting device 3 for each slave device 2 by an operation input on the slave device 2.

At 3, the remote controller 4 outputs a signal equivalent to the control signal transmitted from the signal transmission unit 13 of the parent device 1. However, in this case, since the target slave unit 2 is specified when the remote control signal is transmitted, the address information is unnecessary. From the information signal transmitter 24, the current information (light control rate, address, etc.) of the child device 2 can be transmitted to the remote controller 4. This allows the user to easily understand the information of the child device 2. Further, the child device 2 can make a control request for another child device 2 to the parent device 1. For example, the signal transmission unit 22 of the slave 2 transmits a control request signal indicating collective control of the slave 2 to the master 1, and the master 1 receives the control request signal at the signal receiver 14. The control unit 15 creates a control signal based on the content of the control request signal, and the signal transmission unit 13 transmits the control signal to all the slaves 2. The control request signal is composed of a signal indicating a dimming level and a lamp blinking state. When the slave unit 2 receives the control signal at the signal receiving unit 14, the slave unit 2 controls the lighting fixture 3 connected thereto based on the content of the received control signal. This allows the user to collectively control all the lighting fixtures 3 from the remote controller 4. In the present embodiment, since the master unit 1 can be operated by the remote controller 4, it is not necessary to separately install an operation terminal for operating the master unit 1, and all the slave units 2 operate the master unit 1. Since it can be a terminal, it is not necessary to install a specific operation terminal, and the wiring becomes simple. Therefore, the wiring can be saved, the layout is not restricted by the position of the operation terminal, and the degree of freedom of layout is increased. Moreover, since it is equivalent to that there are as many operating terminals as the parent device 1 as the number of the child devices 2, it is easy to operate the parent device 1 and convenience is improved.
