(First embodiment)
First, the first embodiment will be described.
Drawing 1 is a figure showing the example of composition of lighting system 1 concerning an embodiment.
The illumination system 1 is a system that causes the illumination device 20 to emit light using electric power from the power supply 2. Moreover, the illumination system 1 dimmes the illumination device 20 based on various parameters. The lighting system 1 is installed in, for example, a house, an office, or a commercial facility.

  The power source 2 supplies power to the lighting system 1. For example, the power supply 2 supplies an alternating voltage. For example, the power source 2 is a commercial power source. For example, the power source 2 is 100 V and supplies an AC voltage that is 50 Hz or 60 Hz. The power supply 2 may supply a direct current.

  As illustrated in FIG. 1, the lighting system 1 includes a controller 10 (lighting control device), a lighting device 20, a controlled device, and the like. In the example shown in FIG. 1, the lighting system 1 includes a relay 30 (power switch), a human sensor 40, an illuminance sensor 50, and a switch 60 as controlled devices. The controller 10 is connected to the lighting device 20 via a dimming signal line. The controller 10 is connected to the relay 30, the human sensor 40, the illuminance sensor 50, and the switch 60 through the transmission signal line. Moreover, the illuminating device 20 is connected to the power supply 2 via a power line.

  The controller 10 controls the entire lighting system 1. For example, the controller 10 generates a dimming signal for controlling the dimming of the lighting device 20 in the lighting device 20 based on a transmission signal from the human sensor 40, the illuminance sensor 50, the switch 60, or the like.

The controller 10 transmits and receives transmission signals to and from the controlled device. That is, the controller 10 transmits and receives transmission signals to and from the relay 30, the human sensor 40, the illuminance sensor 50, and the switch 60. The transmission signal is a signal for transmitting / receiving data to / from the controller 10, the relay 30, the human sensor 40, the illuminance sensor 50, and the switch 60 (controlled device).
The controller 10 will be described in detail later.

The lighting device 20 emits light based on the dimming signal from the controller 10. In other words, the lighting device 20 emits the amount of light indicated by the dimming signal.
The lighting device 20 includes, for example, a control unit and a lighting load. A control part performs control which supplies electric power to lighting load according to a light control signal. That is, the control unit performs control to supply the power that the illumination load emits the light amount indicated by the dimming signal. The illumination load emits light according to the supplied power. For example, the illumination load is a light emitting diode, a fluorescent lamp, an incandescent lamp, or the like. In addition, the illumination load of the illuminating device 20 is not limited to a specific structure. Further, the number of lighting loads provided in the lighting device 20 is not limited to a specific number.

  The controlled device is a device controlled by the controller 10. For example, the controlled device is related to the control of the lighting device 20. For example, the controlled device supplies data necessary for controlling the lighting device 20 or performs an operation necessary for controlling the lighting device 20. Hereinafter, the relay 30, the human sensor 40, the illuminance sensor 50, and the switch 60, which are controlled devices, will be described.

  The relay 30 turns on or off the power supply to the lighting device 20 based on the transmission signal from the controller 10. That is, the relay 30 connects or disconnects the power line between the lighting device 20 and the power source 2.

As shown in FIG. 1, the relay 30 includes a switch unit 31 and an amplifier unit 32.
The switch unit 31 is installed on a power line between the lighting device 20 and the power supply 2. The switch unit 31 closes or opens a contact between the lighting device 20 and the power supply 2. For example, the switch unit 31 includes a coil that receives power supply from the power supply 2. The switch unit 31 closes or opens the contact using magnetic force generated from the electric power flowing through the coil.

  The switch unit 31 operates based on the transmission signal. That is, when the transmission signal turns on the power supply to the lighting device 20, the switch unit 31 connects the lighting device 20 and the power source 2. When the transmission signal turns off the power supply to the lighting device 20, the switch unit 31 shuts off the lighting device 20 and the power source 2.

  The amplifier unit 32 amplifies the transmission signal from the controller 10. That is, the amplifier unit 32 amplifies the transmission signal from the controller 10 and outputs the amplified signal to a controlled device downstream from the relay 30 (that is, a controlled device far from the controller 10 on the transmission signal line). In the example illustrated in FIG. 1, the amplifier unit 32 outputs the amplified transmission signal to the human sensor 40, the illuminance sensor 50, and the switch 60. The amplifier unit 32 may amplify a transmission signal from a downstream controlled device and transmit the amplified signal to the controller 10.

  The amplifier unit 32 may amplify the transmission signal based on the transmission signal from the controller 10. For example, when the amplifier unit 32 receives a transmission signal instructing amplification, the amplifier unit 32 amplifies the transmission signal received later and transmits the amplified signal to the downstream controlled device. The amplifier unit 32 may set the amplification amount based on the transmission signal from the controller 10.

The amplifier unit 32 is supplied with power from the power source 2. In other words, the amplifier unit 32 amplifies the transmission signal using the power from the power source 2.
The amplifier unit 32 may receive power from another power source.

  The human sensor 40 detects a person in a predetermined area. For example, the human sensor 40 detects a person in an area illuminated by the lighting device 20. When the human sensor 40 detects a person within a predetermined area, the human sensor 40 transmits a transmission signal indicating that the person has been detected to the controller 10. Note that the human sensor 40 may transmit a transmission signal indicating that there is no person to the controller 10 when detecting that there is no person from the predetermined area.

  The illuminance sensor 50 detects illuminance in a predetermined area. For example, the illuminance sensor 50 detects illuminance in a region illuminated by the lighting device 20. Further, the illuminance sensor 50 may detect the illuminance in the vicinity of the area illuminated by the lighting device 20. For example, the illuminance sensor 50 may detect the illuminance outside a room illuminated by the lighting device 20. The illuminance sensor 50 transmits a transmission signal indicating the detected illuminance to the controller 10.

  The switch 60 receives various operations from the operator. For example, the switch 60 receives an on / off operation of the lighting device 20. Further, the switch 60 may accept an operation indicating the light amount of the lighting device 20. For example, the switch 60 includes a push button switch or a rotary switch. The switch 60 may be composed of a touch panel or the like. The switch 60 transmits a transmission signal indicating the accepted operation to the controller 10.

In addition, the illumination system 1 may include a configuration as necessary in addition to the configuration illustrated in FIG. 1 or may exclude a specific configuration.
For example, the lighting system 1 may not include the human sensor 40, the illuminance sensor 50, or the switch 60. Moreover, the illumination system 1 may include other controlled devices.

Next, the controller 10 will be described.
FIG. 2 is a diagram illustrating a configuration example of the controller 10.
As shown in FIG. 2, the controller 10 includes a CPU 11, a memory 12, a first interface 13, a second interface 14, and the like.

  The CPU 11 has a function of controlling the operation of the entire controller 10. The CPU 11 may include an internal cache and various interfaces. The CPU 11 implements various processes by executing a program stored in advance in the internal memory or the memory 12. The CPU 11 is, for example, a processor.

  Note that some of the various functions realized by the CPU 11 executing the program may be realized by a hardware circuit. In this case, the CPU 11 controls functions executed by the hardware circuit.

  The memory 12 includes a volatile memory and a nonvolatile memory. For example, the memory 12 stores a control program and control data in advance. The memory 12 temporarily stores data being processed by the CPU 11. For example, the memory 12 stores various application programs being executed based on instructions from the CPU 11. The memory 12 may store data necessary for executing the application program, the execution result of the application program, and the like.

  The first interface 13 is an interface for transmitting and receiving data to and from the lighting device 20. For example, the CPU 11 transmits a dimming signal to the lighting device 20 through the first interface 13. For example, a PWM dimming signal is transmitted as the dimming signal. The first interface 13 may support a LAN connection, for example.

  The second interface 14 is an interface for transmitting and receiving data to and from the controlled device (here, the relay 30, the human sensor 40, the illuminance sensor 50, and the switch 60). For example, the CPU 11 transmits a transmission signal to the controlled device through the second interface 14. The second interface 14 is configured to be able to transmit an arbitrary illumination control communication standard, and for example, a communication standard such as DALI can be used. Further, the second interface 14 can adopt a communication protocol different from that of the first interface 13. Further, it is desirable that the second interface 14 is configured to perform transmission / reception of transmission signals and power supply to devices connected to the second interface 14 through two transmission lines. With this configuration, the lighting device 20 connected to the first interface 13 has a simple configuration that can be controlled by a dimming signal, and acquires sensor device information via the second interface. It is possible to control the lighting device 20 or turn on / off the power supply to the lighting device 20 connected to the first interface 13 by the relay 30 connected to the second interface 14. Note that the second interface 14 may support a LAN connection.

The first interface 13 and the second interface 14 may be integrally formed.
Further, the controller 10 may have a configuration as required in addition to the configuration shown in FIG.

Next, functions realized by the CPU 11 will be described.
CPU11 has a function which outputs a light control signal to the illuminating device 20 (light control signal output part).
The CPU 11 determines the amount of light to be emitted to the lighting device 20 based on a transmission signal from the human sensor 40, the illuminance sensor 50, the switch 60, or the like. For example, the CPU 11 determines whether there is a person in the area illuminated by the lighting device 20 based on the transmission signal from the human sensor 40. When there is a person in the area, the CPU 11 determines a large value as the light amount. Further, when there is no person in the area, the CPU 11 determines a small value as the light amount.

  Further, the CPU 11 acquires the illuminance around the area illuminated by the lighting device 20 based on the transmission signal from the illuminance sensor 50. For example, if the illuminance around the area is small, the CPU 11 determines a large value as the light amount. In addition, if the illuminance around the area is large, the CPU 11 determines a small value as the light amount.

  Further, the CPU 11 may determine the amount of light according to an operation input to the switch 60. For example, the CPU 11 may acquire the light amount input to the switch 60 and determine the acquired light amount as the light amount of the illumination device 20.

  The method by which the CPU 11 determines the amount of light is not limited to a specific method.

In addition, the CPU 11 generates a dimming signal indicating the determined light amount. For example, the CPU 11 generates a PWM wave as the dimming signal. For example, the CPU 11 generates a PWM wave having a pulse width corresponding to the amount of light as a dimming signal. Note that the CPU 11 may generate a bit signal indicating the amount of light as a dimming signal. The configuration of the dimming signal generated by the CPU 11 is not limited to a specific configuration.
In addition, the CPU 11 outputs the generated dimming signal to the lighting device 20 through the first interface 13.

The CPU 11 has a function of outputting a transmission signal (third transmission signal) to the controlled device (second transmission signal output unit).
For example, the CPU 11 generates a transmission signal for controlling the controlled device. For example, the CPU 11 generates a transmission signal for performing on / off control of the human sensor 40 or the illuminance sensor 50. The CPU 11 transmits the generated transmission signal to the controlled device through the second interface 14.

  Further, the CPU 11 has a function of outputting a transmission signal for turning on or off the power supply to the lighting device 20 to the relay 30 (first transmission signal output unit). That is, the CPU 11 sends a transmission signal (first transmission signal) for turning on the power supply to the lighting device 20 or a transmission signal (second transmission signal) for turning off the power supply to the lighting device 20 to the relay 30. Output.

For example, the CPU 11 determines to turn on the lighting device 20 in a predetermined case.
For example, when an operation for turning on the lighting device 20 is input to the switch 60, the CPU 11 determines to turn on the lighting device 20. Further, the CPU 11 may determine to turn on the lighting device 20 when it is determined that there is a person in the area illuminated by the lighting device 20 based on the transmission signal from the human sensor 40.

  When the CPU 11 determines to turn on the power of the lighting device 20, the CPU 11 generates a transmission signal for turning on the power supply to the lighting device 20. The CPU 11 transmits the transmission signal generated through the second interface 14 to the relay 30.

Further, the CPU 11 determines to turn off the lighting device 20 in a predetermined case.
For example, when an operation for turning off the lighting device 20 is input to the switch 60, the CPU 11 determines to turn off the power of the lighting device 20. Further, the CPU 11 may determine to turn off the power of the lighting device 20 when it is determined that there is no person in the region illuminated by the lighting device 20 based on the transmission signal from the human sensor 40.

  When the CPU 11 determines to turn off the power of the lighting device 20, the CPU 11 generates a transmission signal for turning off the power supply to the lighting device 20. The CPU 11 transmits the transmission signal generated through the second interface 14 to the relay 30.

Next, an operation example of the illumination system 1 will be described.
Here, it is assumed that the switch unit 31 is turned off (that is, the lighting device 20 is turned off).

  First, the CPU 11 of the controller 10 determines to turn on the lighting device 20 in a predetermined case. As described above, for example, the CPU 11 determines to turn on the lighting device 20 based on a transmission signal from the human sensor 40 or the switch 60.

  When it is determined that the lighting device 20 is to be turned on, the CPU 11 generates a transmission signal for turning on the power supply to the lighting device 20. When the transmission signal is generated, the CPU 11 transmits the transmission signal to the relay 30 through the second interface 14. Note that the CPU 11 may include a bit indicating a transmission signal for the relay 30 in the transmission signal and output the transmission signal to the transmission signal line.

  The relay 30 receives a transmission signal for turning on the power supply to the lighting device 20 from the controller 10. The relay 30 closes the switch unit 31 according to the transmission signal. When the switch unit 31 is closed, the lighting device 20 is activated by receiving power from the power source 2.

When the lighting device 20 is activated, the CPU 11 generates a dimming signal. When the dimming signal is generated, the CPU 11 transmits the dimming signal generated through the first interface 13 to the lighting device 20.
The lighting device 20 receives a dimming signal from the controller 10. When the dimming signal is received, the lighting device 20 emits the amount of light indicated by the dimming signal.

  In addition, the CPU 11 transmits a transmission signal to the transmission signal line through the second interface 14. The CPU 11 may transmit a transmission signal to the transmission signal line before and after the lighting device 20 is activated. Moreover, CPU11 may transmit a transmission signal to a transmission signal line after the illuminating device 20 starts.

  When the CPU 11 transmits a transmission signal to the transmission signal line, the amplifier unit 32 of the relay 30 receives the transmission signal. When receiving the transmission signal, the amplifier unit 32 amplifies the received transmission signal. When the transmission signal is amplified, the amplifier unit 32 outputs the amplified transmission signal to the downstream transmission signal line.

  In addition, the CPU 11 of the controller 10 determines to turn off the lighting device 20 in a predetermined case. As described above, for example, the CPU 11 determines to turn off the lighting device 20 based on a transmission signal from the human sensor 40 or the switch 60.

  When it is determined that the lighting device 20 is to be turned off, the CPU 11 generates a transmission signal for turning off the power supply to the lighting device 20. When the transmission signal is generated, the CPU 11 transmits the transmission signal to the relay 30 through the second interface 14. Note that the CPU 11 may include a bit indicating a transmission signal for the relay 30 in the transmission signal and output the transmission signal to the transmission signal line.

  The relay 30 receives a transmission signal for turning off the power supply to the lighting device 20 from the controller 10. The relay 30 opens the switch unit 31 according to the transmission signal. When the switch unit 31 is opened, the supply of power from the power source 2 to the lighting device 20 is stopped. When the supply of power is stopped, the lighting device 20 ends the operation.

  As described above, the amplifier unit 32 may amplify the transmission signal from the controlled device to the controller 10 downstream. The amplifier unit 32 may amplify the transmission signal based on the transmission signal from the controller 10.

  The controller formed as described above outputs a signal for turning on or off the power supply to the lighting device 20. Further, the relay connected to the controller turns on or off the connection between the lighting device and the power source according to the signal. As a result, the controller can turn on or off the lighting device.

In addition, the relay amplifies a signal for the controlled device by an amplifier unit included in the relay. As a result, the controller can stably transmit a signal to a controlled device installed at a distance or the like. In addition, the amplifier unit receives power from a power source that supplies power to the lighting device 20. As a result, the amplifier unit can amplify the signal without requiring a new power source.
(Second Embodiment)

The transmission signal line connected to the controller 10a is connected to the controller 10b. That is, the controller 10a transmits a transmission signal to the controller 10b.

Next, the controllers 10a and 10b will be described.
Here, the controller 10b will be described. The controller 10a has the same configuration as the controller 10b.

FIG. 4 is a diagram illustrating a configuration example of the controller 10b.
As shown in FIG. 4, the controller 10b includes a CPU 11b, a memory 12b, a first interface 13b, a second interface 14b, a third interface 15b (communication unit), an operation unit 16b, and the like.

  Since the memory 12b, the first interface 13b, and the second interface 14b are the same as the memory 12, the first interface 13, and the second interface 14, respectively, description thereof is omitted.

  The CPU 11b has a function of controlling the overall operation of the controller 10b. The CPU 11b may include an internal cache and various interfaces. The CPU 11b implements various processes by executing a program stored in advance in the internal memory or the memory 12b. The CPU 11b is, for example, a processor.

  Note that some of the various functions realized by the CPU 11b executing the program may be realized by a hardware circuit. In this case, the CPU 11b controls functions executed by the hardware circuit.

The third interface 15b is an interface for transmitting / receiving data to / from a higher-level lighting system. That is, the third interface 15b transmits and receives transmission signals to and from the controller (here, the controller 10a) of the higher-level lighting system. For example, the third interface 15b is connected to the transmission signal line of the upper lighting system. The CPU 11b receives a transmission signal through the third interface 15b. For example, the third interface 15b may support a LAN connection.
Note that the first interface 13b, the second interface 14b, and the third interface 15b may be integrally formed.

  The operation unit 16b receives an operation for instructing to operate as a controlled device of a higher-level lighting system from the operator. The operation unit 16b transmits the received operation to the CPU 11b. The operation unit 16b is configured by, for example, a switch or a touch panel.

Further, the controller 10b may include a configuration as necessary in addition to the configuration illustrated in FIG. 4 or may exclude a specific configuration.
The controller 10a includes a CPU 11a, a memory 12a, a first interface 13a, a second interface 14a, a third interface 15a, an operation unit 16a, and the like (not shown). The CPU 11a, the memory 12a, the first interface 13a, the second interface 14a, the third interface 15a, and the operation unit 16a are respectively the CPU 11b, the memory 12b, the first interface 13b, the second interface 14b, and the third interface. Since it is the same as 15b and operation part 16b, explanation is omitted.

Next, functions of the CPU 11b will be described.
The CPU 11b realizes the following functions in addition to the functions of the CPU 11 of the first embodiment.
The CPU 11 has a function of setting a slave mode (operating as a slave of the host controller) that operates as a controlled device of the host lighting system (operating mode setting unit).
For example, when the CPU 11b receives an operation for instructing to operate as a controlled device of a higher-level lighting system through the operation unit 16b, the CPU 11b sets the operation mode to the slave mode. Further, the CPU 11b may set the operation mode to the slave mode based on detection of connection between the third interface 15b and the transmission signal line (that is, the host controller).

The slave mode is an operation mode that operates as a controlled device of the host lighting system. That is, the slave mode is a mode that operates under the control of the controller of the host lighting system.
Here, it is assumed that the lighting system 1a is a higher-level lighting system.
When the slave mode is set, the CPU 11b controls each part of the lighting system 1b based on a transmission signal received from the controller 10a through the third interface 15b. For example, the CPU 11b receives a transmission signal for turning on the lighting device 20b from the controller 10a. When the transmission signal is received, the CPU 11b turns on the lighting device 20b according to the transmission signal. The operation of the CPU 11b for turning on the power of the lighting device 20b is the same as the operation of the first embodiment, and a description thereof will be omitted.

  In addition, the CPU 11b receives a transmission signal indicating the light amount of the illumination device 20b from the controller 10a. When the transmission signal is received, the CPU 11b adjusts the lighting device 20b so as to emit the amount of light indicated by the transmission signal. The operation of the CPU 11b for dimming the lighting device 20b is the same as the operation of the first embodiment, and a description thereof will be omitted.

Further, the CPU 11b may transmit a transmission signal to the controller 10a through the third interface 15b. For example, the CPU 11b may transmit a transmission signal from a controlled device (such as the human sensor 40b, the illuminance sensor 50b, or the switch 60b) of the lighting system 1b to the controller 10a.
Note that the controller (here, the controller 10a) of the illumination system described above may not include the third interface 15a and the operation unit 16a.

Next, an operation example of the integrated system 100 will be described.
Here, it is assumed that the CPU 11a of the illumination system 1a operates in an operation mode (master mode) for controlling the illumination system 1b that operates in the slave mode.

  First, the CPU 11b determines whether to set the slave mode. As described above, for example, the CPU 11b determines whether an instruction to operate in the slave mode is received through the operation unit 16b. Further, the CPU 11b determines whether a transmission signal line is connected to the third interface 15b. Here, it is assumed that the CPU 11b determines to set the slave mode.

When determining that the slave mode is set, the CPU 11b sets the operation mode to the slave mode.
When the CPU 11b sets the operation mode to the slave mode, the CPU 11a of the illumination system 1a transmits a transmission signal to the controller 10b through the second interface 14b. For example, the CPU 11a transmits, to the controller 10b, a transmission signal for turning on / off the power of the lighting device 20b, a transmission signal indicating the light amount of the lighting device 20b, and the like.

  The CPU 11b of the controller 10b receives a transmission signal from the controller 10a through the third interface 15b. When receiving the transmission signal, the CPU 11b controls each part of the illumination system 1b based on the transmission signal.

  When the operation mode is set to the slave mode, the CPU 11b may transmit a transmission signal from the controlled device of the illumination system 1b to the controller 10a as described above.

  The controller configured as described above sets the operation mode to a slave mode that operates as a slave of the upper lighting system. Therefore, the controller can operate under the control of the controller of the upper lighting system. As a result, the integrated system can easily increase the lighting system. In addition, the integrated system can easily link the lighting systems.
