The lighting device 13 blinks (turns on / off) according to the operation of the wall switch 16, the detection state of the human sensor 14, the illuminance value monitored by the illuminance sensor 15, and the like. Control the dimming state. The controller 11 also includes a storage unit 31 that stores setting data for initial illuminance correction. In the present embodiment, the setting data is data for setting a pattern that changes the dimming rate of the light source as the cumulative lighting time of the light source of the lighting device 13 elapses. A specific example of the setting data will be described later. The storage unit 31 is, for example, a nonvolatile memory (ROM, flash memory, etc.).

  The communication unit 12 performs wireless communication or wired communication with the controller 11. This communication is called upper communication. The communication unit 12 performs two-wire serial communication (bidirectional communication) via the lighting device 13, the human sensor 14, the illuminance sensor 15, the wall switch 16, and the signal line. This communication is called subordinate communication. The communication unit 12 has a gateway function between upper communication and lower communication. Specifically, the communication unit 12 converts a signal related to data setting, monitoring instruction, and illumination control (lighting, turning off, dimming, etc.) received from the controller 11 by wireless communication or wired communication into a two-wire wired serial signal. The individual address which becomes a serial number is previously allocated to each illumination device 13, the human sensor 14, the illuminance sensor 15, and the wall switch 16, and data setting, monitoring instruction, and illumination control are performed individually.

  The controller 11 and the communication unit 12 may be integrated so that the controller 11 communicates directly with the lighting device 13, the human sensor 14, the illuminance sensor 15, and the wall switch 16. Communication between the communication unit 12 (or the controller 11 integrated with the communication unit 12) and the lighting device 13, the human sensor 14, the illuminance sensor 15, and the wall switch 16 is performed by any communication method other than wired serial communication. You may go.

  As shown in FIG. 1, the lighting device 13, the human sensor 14, the illuminance sensor 15, and the wall switch 16 may be connected to a single communication unit 12, or may be connected to a single communication unit 12. A plurality of devices (for example, lighting device 13) may be connected to 12, or may be connected to one communication unit 12 in any other combination. That is, the overall configuration of the lighting control system 10 is determined according to the aspect of the lighting system to be constructed.

  The illuminating device 13 is an instrument including an LED, a fluorescent lamp, an organic EL, or other light source, and a lighting circuit that lights the light source. The lighting device 13 turns on or off the light source or changes the brightness (output) of the light source according to a signal (signal related to lighting control) transmitted from the controller 11 via the communication unit 12.

  The human sensor 14 detects the presence / absence of a person in a specific area (detection area) in accordance with a signal (a signal related to data setting or a monitoring instruction) transmitted from the controller 11 via the communication unit 12. Then, the detection information indicating the result is notified to the controller 11.

  The illuminance sensor 15 measures the illuminance (for example, the illuminance on the desk surface) in a specific area around the signal (signal related to data setting or monitoring instruction) transmitted from the controller 11 via the communication unit 12. The illuminance information indicating the result is notified to the controller 11.

  The wall switch 16 is operated by a user (for example, a button is pressed) for lighting control and dimming control of the light source of the lighting device 13. When the wall switch 16 is operated by the user, the wall switch 16 notifies the controller 11 of operation information indicating the state (for example, button press).

  The wireless remote controller 17 performs wireless communication with the controller 11 and the communication unit 12, lighting control and dimming control of the light source of the lighting device 13, and status monitoring and data of each device including the controller 11 and the communication unit 12 by a user's remote operation. Set up. The wireless remote controller 17 also includes an input unit 32a that receives input of setting data from the user.

  The setting device 18 is, for example, a PC (Personal Computer), performs wireless communication or wired communication with the controller 11 or the communication unit 12, and controls lighting or dimming control of the light source of the lighting device 13 from the screen, the controller 11 or the communication unit 12. The status monitor and data setting of each device including The setting device 18 includes an input unit 32 b similar to the input unit 32 a of the wireless remote controller 17.

  The input units 32a and 32b included in the wireless remote controller 17 and the setting device 18 are input devices for manually inputting setting data (for example, a button or a touch panel for the wireless remote controller 17 or a mouse for the PC setting device 18). Or keyboard). The input units 32a and 32b allow the user to directly input setting data via the input device. The wireless remote controller 17 and the setting device 18 transmit the setting data input to the input units 32 a and 32 b to the controller 11. The controller 11 receives setting data transmitted from the wireless remote controller 17 or the setting device 18 and stores the setting data in the storage unit 31. Then, the controller 11 transmits the setting data stored in the storage unit 31 to the lighting device 13 via the communication unit 12.

  Note that the input units 32a and 32b may accept input of setting data via an external storage device instead of directly accepting input of setting data from the user. For example, the input units 32 a and 32 b are connected to a storage device (for example, a server computer on a network such as the Internet) that stores setting data in advance for each of a plurality of types of light sources that can be used as the light source of the lighting device 13. Suppose that In this case, the input units 32a and 32b cause the user to select the type of light source on the screen, and obtain setting data corresponding to the selected type from the storage device. Alternatively, for example, it is assumed that a storage device (for example, a memory card) that stores setting data in advance is detachably attached to the input units 32a and 32b. When the storage device is attached by the user, the input units 32a and 32b acquire setting data from the storage device.

  The control unit 21 includes a measurement unit 33a and a light control unit 34a.

  The measuring unit 33 a of the control unit 21 measures (counts) the cumulative lighting time of the LED light source 23. When the LED light source 23 is replaced, the cumulative lighting time count is reset.

  The light control unit 34 a of the control unit 21 performs wired communication with the communication unit 12 and receives setting data transmitted from the controller 11 via the communication unit 12. The dimming unit 34a obtains the dimming rate of the LED light source 23 corresponding to the cumulative lighting time measured by the measuring unit 33a in accordance with the pattern set by the received setting data. And the light control part 34a light-controls the LED light source 23 with the calculated | required light control rate. Specifically, the dimming unit 34 a outputs a PWM (pulse width modulation) dimming signal indicating the obtained dimming rate to the LED power supply device 22. The dimming unit 34a outputs a turn-off signal with a dimming rate of 0% when receiving a turn-off command from the communication unit 12, and outputs the PWM dimming signal only when a turn-on command is received.

  The LED power supply device 22 turns on or off the LED light source 23 or performs dimming according to the PWM dimming signal from the control unit 21.

  The LED light source 23 is a light source on which an LED chip is mounted, and is driven by the LED power supply device 22.

  As described above, when receiving the setting data from the communication unit 12, the control unit 21 analyzes the received setting data, and changes the PWM dimming signal output to the LED power supply device 22 based on the analysis result. By doing so, the brightness of the LED light source 23 is changed. The control unit 21 includes an initial illuminance correction function that increases the dimming rate so as to compensate for the luminous flux of the LED light source 23 that decreases in accordance with the cumulative lighting time of the LED light source 23.

  FIG. 3 is a block diagram showing a configuration of the illumination device 13 (in the case of a fluorescent lamp) connected to the communication unit 12.

  In FIG. 3, the lighting device 13 includes a control unit 21, an inverter 24, and a fluorescent lamp 25.

  The control unit 21 includes a measurement unit 33b and a light control unit 34b.

  The measuring unit 33b of the control unit 21 measures (counts) the cumulative lighting time of the fluorescent lamp 25. When the fluorescent lamp 25 is replaced, the cumulative lighting time count is reset.

  The dimming unit 34 b of the control unit 21 performs wired communication with the communication unit 12 and receives setting data transmitted from the controller 11 via the communication unit 12. The dimming unit 34b obtains the dimming rate of the fluorescent lamp 25 corresponding to the cumulative lighting time measured by the measuring unit 33b in accordance with the pattern set by the received setting data. And the light control part 34b light-controls the fluorescent lamp 25 with the calculated | required light control rate. Specifically, the dimming unit 34 b outputs a PWM dimming signal indicating the obtained dimming rate to the inverter 24. The dimming unit 34b outputs a turn-off signal with a dimming rate of 0% when receiving a turn-off command from the communication unit 12, and outputs the PWM dimming signal only when a turn-on command is received.

  The inverter 24 turns on or off the fluorescent lamp 25 or performs dimming according to the PWM dimming signal from the control unit 21.

  The fluorescent lamp 25 is driven by the inverter 24.

  As described above, when receiving the setting data from the communication unit 12, the control unit 21 analyzes the received setting data and changes the PWM dimming signal output to the inverter 24 based on the analysis result. Thus, the brightness of the fluorescent lamp 25 is changed. The control unit 21 includes an initial illuminance correction function that increases the dimming rate so as to compensate for the luminous flux of the fluorescent lamp 25 that decreases in accordance with the cumulative lighting time of the fluorescent lamp 25.

  The LED light source 23 of the illuminating device 13 in FIG. 2 and the fluorescent lamp 25 of the illuminating device 13 in FIG. 3 have different attenuation rates of the lamp luminous flux according to the cumulative lighting time. Therefore, the control unit 21 performs the initial illuminance correction. It is necessary to change how the dimming rate increases. Also in the lighting device 13 (in the case of LED) in FIG. 2, the attenuation factor of the lamp luminous flux according to the cumulative lighting time differs depending on the manufacturer and specification of the LED chip, so that the control unit 21 performs the initial illuminance correction. It is necessary to change how the dimming rate increases. That is, the control unit 21 needs to change the dimming characteristics (pattern for changing the dimming rate) in the initial illuminance correction depending on the type of light source and the product (mold). In addition, since the light source may be exchanged, the control unit 21 must be able to change the dimming characteristics even after the lighting device 13 is installed.

  The control unit 21 of the lighting device 13 belonging to the group 1 receives the group dimming rate command from the communication unit 12, and according to the dimming rate data included in the group dimming rate command, the light source such as the LED light source 23 and the fluorescent lamp 25 Turn off the light.

  FIG. 12 is a diagram illustrating an example of a communication sequence of the illumination control system 10 (when initial illumination correction is disabled).

  In the example of FIG. 12, it is assumed that the lighting devices 13 are grouped and the initial illuminance correction of the control unit 21 of the lighting devices 13 belonging to the group 1 is invalidated.

  First, the setting device 18 (which may be the wireless remote controller 17 or the central management device 20 of the second and third embodiments) transmits a setting signal for invalidating the initial illuminance correction of the group 1 to the controller 11.

  The controller 11 receives the setting signal from the setting device 18, and switches the group 1 to the dimming rate fixed mode (example of the second mode) based on the received setting signal.

  When the wall switch 16 is pressed, the controller 11 transmits a group dimming rate command for lighting the group 1 to the address of the lighting device 13 belonging to the group 1. This group dimming rate command includes, for example, dimming rate data indicating 8 C% (hexadecimal) as a value for directly commanding the dimming rate. Here, the value for instructing the dimming rate is assumed to be the actual dimming rate × n (n = 2 in this example). Therefore, 8 C% means a dimming rate of 70%.

  The communication unit 12 receives the group dimming rate command from the controller 11 and transfers it to the lighting devices 13 belonging to the group 1.

  The control unit 21 of the lighting device 13 belonging to the group 1 receives the group dimming rate command from the communication unit 12, and according to the dimming rate data included in the group dimming rate command, the light source such as the LED light source 23 and the fluorescent lamp 25 Is turned on at a dimming rate of 70%.

  Thereafter, when the wall switch 16 is pressed, the controller 11 transmits a group dimming rate command for turning off the group 1 to the address of the lighting device 13 belonging to the group 1. This group dimming rate command includes, for example, dimming rate data indicating 00% (hexadecimal number) as a value for directly commanding the dimming rate.

  The communication unit 12 receives the group dimming rate command from the controller 11 and transfers it to the lighting devices 13 belonging to the group 1.

  The control unit 21 of the lighting device 13 belonging to the group 1 receives the group dimming rate command from the communication unit 12, and according to the dimming rate data included in the group dimming rate command, the light source such as the LED light source 23 and the fluorescent lamp 25 Turn off the light.

  Note that the control unit 21 of the lighting device 13 counts the cumulative lighting time even in the dimming rate fixed mode, and when switching to the initial illuminance correction mode, the initial illuminance correction can be performed from the count value of the cumulative lighting time. Keep it.

  According to the present embodiment, the user can arbitrarily determine whether or not to perform the initial illuminance correction.
