[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2010-238572 Summary of the Invention [Problem to be solved by the invention]

[0004] However, in lighting devices and lighting control systems connected to an external network such as the Internet, if a malfunction occurs in the control server's program or if a malicious third party performs unauthorized operations via the external network, the control server may send an inappropriate control signal, causing the lighting device to unnecessarily turn off or blink, creating an uncomfortable lighting environment for users near the lighting device. In such cases, a comfortable lighting environment for users can be maintained by disconnecting communication between the lighting control system and the external network and disabling remote control. However, lighting devices and lighting control systems connected to an external network have the problem that it is difficult for users to disconnect communication between the lighting control system and the external network.

[0005] In order to solve the above-mentioned problems, the present disclosure aims to provide a lighting device and a lighting control system that allow a user to disable remote control if the remote control creates an uncomfortable lighting environment for the user. [Means for solving the problem]

[0007] In addition, the lighting device according to the present disclosure irradiates light into a space in which it is installed and includes a light source unit, a communication unit that communicates with a control server via an external network, a control unit that remotely controls the light source unit based on a control signal received by the communication unit from the external network, and a power supply determination means that determines whether the power supply state to the lighting device is on or off, and the control unit disables the remote control when the power supply state determined by the power supply determination means is in a predetermined pattern. [Effects of the Invention]

[0010] The following description will discuss embodiments of the present disclosure with reference to the accompanying drawings. In each drawing, identical or corresponding parts are designated by the same reference numerals, and redundant descriptions are appropriately simplified or omitted. The present disclosure is not limited to the following embodiments, and any of the components of the embodiments may be modified, combined, or omitted without departing from the spirit of the present disclosure.

[0011] Embodiment 1 Fig. 1 is a diagram showing an example of the configuration of a lighting control system 100 according to embodiment 1. As shown in Fig. 1, lighting control system 100 includes a plurality of lighting devices 1, sensors 12, switches 13, and a connection device 50. Connection device 50 of lighting control system 100 is connected to a control server 400 via an external network 300.

[0012] The external network 300 is a network such as the Internet that allows communication between remote devices.

[0013] The control server 400 transmits a control signal indicating the control content of the lighting control system 100 to the lighting control system 100 via the external network 300. The control signal is generated by a program executed on the control server 400. Alternatively, the control server 400 generates the control signal based on a signal generated by an operator operating a communication terminal (not shown) such as a smartphone or a PC and transmitted to the control server 400.

[0014] The external power supply 200 supplies power to the illumination lighting device 1 and the sensor 12 that constitute the illumination control system 100 via an electric wire 15 .

[0015] The connection device 50 is a gateway device that relays communication between the external network 300 and the dedicated network 10 that is made up of a plurality of illumination lighting devices 1 and sensors 12.

[0016] The dedicated network 10 is a network dedicated to the lighting control system 100, which connects lighting devices 1 and sensors 12 installed in one building or a limited area, and is used for communicating signals related to the control of the lighting devices 1.

[0017] The communication between the connection device 50 and the dedicated network 10, and the communication within the dedicated network 10, are carried out using a communication cable such as a LAN (Local Area Network) cable, or wireless communication.

[0018] The illumination lighting device 1 has a light source unit 8 such as an LED, and emits light into the space in which it is installed, as will be described in detail later.

[0019] The sensor 12 is a sensor, such as a human presence sensor or an illuminance sensor, that acquires information used to control the lighting device 1. The detection result of the sensor 12 is output to the lighting device 1, and the lighting device 1 controls dimming according to the output result.

[0020] The switch 13 is provided on an electric wire 15 connecting the external power source 200 to the lighting device 1 and the sensor 12. The switch 13 can switch the state of the power supply from the external power source 200 between on and off by mechanical operation by a user. Here, the user refers to a person who is near the location where the lighting control system is installed and who can operate the switch 13. Mechanical operation refers to the user operating an operating unit such as a switch, lever, or handle that operates based on a mechanical action. The switch 13 is, for example, a wall switch provided on the wall of the room where the lighting device 1 is installed, or a breaker that cuts off power from the external power source 200. The switch 13 functions as an operating unit in this embodiment. When the user mechanically operates the operating unit, the lighting device 1 disables remote control, which will be described later.

[0021] 2 is a schematic diagram showing the circuit configuration of the illumination lighting device 1 according to the first embodiment. The illumination lighting device 1 includes a control unit 2, a communication unit 3, a diode bridge 4, an input voltage detection circuit 5, a DC power supply circuit 6, a converter circuit 7, a light source unit 8, and a control power supply generation circuit 9. The illumination lighting device 1 controls the current flowing through the light source unit 8 to turn on the light source unit 8. The light source unit 8 is, for example, an LED.

[0022] The diode bridge 4 performs full-wave rectification on the AC power supplied from the external power supply 200 and converts it into a DC voltage. The high-potential side of the output of the diode bridge 4 is connected to the input voltage detection circuit 5, and the low-potential side is connected to the GND potential.

[0023] The input voltage detection circuit 5 includes resistors 5a and 5b connected in series, and divides the input voltage. This allows the divided voltage to be detected by the control unit 2, making it possible to detect the input voltage from the external power supply 200. The input voltage detection circuit 5 is a power supply detection means that detects the power supply state from the external power supply 200 in the illumination lighting device 1.

[0024] The DC power supply circuit 6 converts the DC voltage input from the diode bridge 4 into a voltage suitable for the converter circuit 7. The DC power supply circuit 6 includes a reactor 6a, a diode 6b, a switching element 6c, a drive circuit 6d, resistors 6e and 6f, and a capacitor 6g. One end of the reactor 6a is connected to the output end of the diode bridge 4. The other end of the reactor 6a is connected to the switching element 6c and the diode 6b. The switching element 6c is, for example, a metal-oxide-semiconductor field-effect transistor (MOSFET). When the switching element 6c is a MOSFET, the first terminal is a drain terminal, the second terminal is a source terminal, and the control terminal is a gate terminal. In the switching element 6c, the first terminal is connected to the anode of the reactor 6a and the diode 6b, the second terminal is connected to the GND potential, and the control terminal is connected to the drive circuit 6d. The drive circuit 6d is a driver for switching control. Resistors 6e and 6f are provided at the output terminal of the DC power supply circuit 6 and are used to detect the output voltage of the DC power supply circuit 6. The voltage divided by resistors 6e and 6f is input to the control unit 2. Based on the detected voltage, the control unit 2 switches on and off the switching element 6c via the drive circuit 6d so that the output voltage of the DC power supply circuit 6 remains constant. The cathode of diode 6b is connected to the positive electrode of capacitor 6g. The negative electrode of capacitor 6g is connected to the GND potential.

[0025] The operation of the DC power supply circuit 6 will now be described. The drive circuit 6d switches the switching element 6c on and off in response to a signal from the control unit 2 based on the output voltage of the DC power supply circuit 6. When the switching element 6c is on, current flows through the reactor 6a and the switching element 6c, applying a voltage to the reactor 6a and storing power. When the switching element 6c is turned off, the power stored in the reactor 6a is released via the diode 6b and stored in the capacitor 6g. The control unit 2 divides the voltage of the DC power stored in the capacitor 6g using resistors 6e and 6f to detect it, and changes the on / off ratio of the switching element 6c so that the detected voltage is suitable for the converter circuit 7. That is, the control unit 2 performs negative feedback control by shortening the on-time of the switching element 6c if the output voltage of the DC power supply circuit 6 is higher than the voltage suitable for the converter circuit 7, and lengthening the on-time if the output voltage is lower than the voltage suitable for the converter circuit 7.

[0026] The converter circuit 7 converts the voltage input from the DC power supply circuit 6 into a voltage suitable for lighting the light source unit 8 and outputs it to the light source unit 8. The converter circuit 7 includes a switching element 7a, a reactor 7b, a drive circuit 7c, a diode 7d, a capacitor 7e, and a detection resistor 7f. The switching element 7a is, for example, a MOSFET. The switching element 7a has a first terminal connected to the positive electrode of the capacitor 6g, a second terminal connected to the cathode of the diode 7d and the reactor 7b, and a control terminal connected to the drive circuit 7c. The drive circuit 7c is a driver for switching control. The other end of the reactor 7b is connected to the positive electrode of the capacitor 7e. The anode of the diode 7d is connected to the negative electrode of the capacitor 7e and one end of the detection resistor 7f. The other end of the detection resistor 7f is connected to the control unit 2. The detection resistor 7f is used to detect the output current of the converter circuit 7, i.e., the current flowing through the light source unit 8. The output current of the converter circuit 7 is converted into a voltage by the detection resistor 7 f and input to the control unit 2 .

[0027] The operation of the converter circuit 7 will now be described. The control unit 2 keeps the output current of the converter circuit 7 constant by switching the switching element 7a on and off via the drive circuit 7c so that the voltage detected by the detection resistor 7f becomes a predetermined value. When the switching element 7a is on, the power stored in the capacitor 6g is supplied to the reactor 7b, capacitor 7e, and light source unit 8. When the switching element 7a is off, the power stored in the reactor 7b and capacitor 7e is supplied to the light source unit 8 via the diode 7d. The control unit 2 changes the on / off ratio of the switching element 7a via the detection resistor 7f so that the current flowing through the light source unit 8 becomes a predetermined value. As a result, a predetermined DC current flows through the light source unit 8, allowing brightness to be controlled.

[0028] The control power generation circuit 9 converts the power supplied from the external power supply 200 via the diode bridge 4 into a voltage appropriate for driving the control unit 2, and supplies the power to the control unit 2. The control power generation circuit 9 includes a voltage conversion unit 9a and a capacitor 9b. The voltage conversion unit 9a is a converter circuit that converts the power supplied from the external power supply 200 into a voltage appropriate for driving the control unit 2. When power is being supplied to the control power generation circuit 9 from the external power supply 200, the control power generation circuit 9 stores power in the capacitor 9b, so that when the power supply from the external power supply 200 is cut off, the capacitor 9b can supply power to the control unit 2. The capacitor 9b functions as a power storage unit that supplies power to the control unit 2 when the power supply to the lighting device 1 is cut off.

[0029] The communication unit 3 is communicably connected to the external network 300 via the connection device 50. The communication unit 3 receives a control signal for the light lighting device 1 from a control server 400 on the external network 300. Upon receiving the control signal, the communication unit 3 transmits the control signal to the control unit 2. The communication unit 3 and the connection device 50 are connected by a communication cable such as a LAN cable. Alternatively, the communication unit 3 and the connection device 50 may communicate wirelessly. In the present embodiment, the communication unit 3 may be communicably connected directly to the external network 300 without going through the connection device 50. In the present disclosure, controlling the light lighting device 1 based on a control signal received by the light lighting device 1 via the external network 300 is referred to as remote control.

[0030] The control unit 2 can be realized by various types of arithmetic devices such as a processor or a microcomputer. For example, various types of microcomputers are already known as digital power supply control devices, and these known microcomputers can be used as appropriate for the control unit 2. The control unit 2 can also be configured by an arithmetic device such as a DSP (Digital Signal Processor). The control unit 2 may also be configured by multiple arithmetic devices. The control unit 2 also includes a storage unit (not shown) such as a nonvolatile memory, which stores the arithmetic program to be executed by the control unit 2 and various data used for the arithmetic.

[0031] The control unit 2 controls the drive circuit 6d based on the output voltage of the DC power supply circuit 6 to switch the switching element 6c on and off. The control unit 2 controls the drive circuit 7c based on a voltage corresponding to the output current of the converter circuit 7, which is the current flowing through the light source unit 8, to switch the switching element 7a on and off. The control unit 2 controls the drive circuit 7c based on a control signal input from the communication unit 3 to control the dimming rate of the light source unit 8. The control unit 2 is also connected to a remote control 16 and receives a control signal from the remote control 16. The control unit 2 controls the dimming rate of the light source unit 8 by controlling the drive circuit 7c based on the control signal. The control unit 2 is also connected to a sensor 12 and receives the detection result of the sensor 12 as input. The control unit 2 controls the dimming rate of the light source unit 8 based on the detection result of the sensor 12. For example, if the sensor 12 is a human presence sensor, the control unit 2 turns on the light source unit 8 when the human presence sensor detects a person. Control of the lighting device 1 that does not require an external network 300, such as when the user operates the remote control 16 and the control unit 2 controls the light source unit 8 in response to a control signal sent from the remote control 16 or the detection result of the sensor 12, is called local control.

[0032] Furthermore, the control unit 2 receives a voltage divided by resistors 5a and 5b of the input voltage detection circuit 5, which is a power supply state grasping means, and can grasp the power supply state from the external power source 200 in the illumination lighting device 1. The control unit 2 has a timer unit (not shown) that measures time, and measures the time when the power supply from the external power source 200 is cut off and the time when it is energized.

[0033] FIG. 3 is an example of a timing chart of the power supply state showing a remote control invalid pattern. The memory unit of the control unit 2 stores the remote control invalid pattern shown in FIG. 3. The remote control invalid pattern is a preset pattern of timing for switching between power supply interruption and power supply. When the power supply interruption and power supply are switched in the remote control invalid pattern, the control unit 2 disables remote control. For example, when the remote control invalid pattern shown in FIG. 3 is set in the control unit 2, remote control is disabled when the power supply is interrupted for 1 to 2 seconds, then powered on for 1 to 2 seconds, and then interrupted again for 1 to 2 seconds and then powered on. When a user wants to disable remote control of the lighting control system 100, the user operates the switch 13, which is an operation unit, to set the remote control invalid pattern, switching between power supply interruption and power supply. Because the power supply interruption and power supply switching are based on the user's operation of the switch 13, it is desirable to have a wide range of timing, such as 1 to 2 seconds, for switching between power supply interruption and power supply in the remote control invalid pattern, as shown in FIG. 3.

[0034] 4 is a flowchart showing the process of disabling remote control in the control unit 2. The process of disabling remote control is started in step S101 when the control unit 2 detects a power supply interruption by the power supply status grasping means while remote control is enabled. The power supply interruption is performed by the user operating the switch 13.

[0035] Next, in step S102, the control unit 2 starts storing the power supply state pattern. At this time, power supply from the external power source 200 is cut off, but the control power generation circuit 9 supplies the power stored in the capacitor 9b to the control unit 2, allowing the control unit 2 to operate. The power supply state pattern is stored for a fixed time. This fixed time is set in advance to be a time longer than the remote control invalid pattern. For example, when the remote control invalid pattern is as shown in Figure 3, the remote control invalid pattern is a maximum of 6 seconds, so the control unit 2 is set to store the power supply state pattern for 6 seconds. Next, proceed to step S103.

[0036] Next, in step S103, the control unit 2 compares the power supply state pattern stored in step S102 with the remote control invalid pattern. If it is determined that the power supply state pattern matches the remote control invalid pattern (step S103: Yes), the process proceeds to step S104. If it is determined that the power supply state pattern does not match the remote control invalid pattern (step S103: No), the process returns to step S101.

[0037] Next, in step S104, the control unit 2 disables the remote control. That is, the control unit 2 ignores any control signal input from the communication unit 3, and performs only local control, which is control of the light source unit 8 based on the control signal from the remote control 16 and control of the light source unit 8 according to the detection result of the sensor 12. Furthermore, when the remote control is disabled, the control unit 2 may set the light source unit 8 to be always on. This completes the remote control disable process.

[0038] Furthermore, in step S104, the control unit 2 may blink the light source unit 8 several times to notify the user that the remote control has been disabled. This allows the user to confirm that the remote control has been disabled by operating the switch 13. Furthermore, if the remote control 16 has a display unit such as a display, the control unit 2 may display on the display unit of the remote control 16 that the remote control has been disabled.

[0039] Furthermore, to notify the user that remote control is disabled, the control unit 2 may blink the light source unit 8 several times at predetermined time intervals, for example, every hour. This allows the user to confirm whether remote control of the illumination lighting device 1 is enabled or disabled. Note that the control of the light source unit 8 to notify the user that remote control is disabled is not limited to blinking the light source unit 8 several times at regular time intervals, and may involve predetermined lighting control, such as changing the dimming rate or color temperature at regular intervals.

[0040] When remote control is disabled, blinking the light source unit 8 at predetermined time intervals or displaying on the display unit of the remote controller 16 that remote control is disabled are notification means for notifying the user that remote control is disabled.

[0041] Furthermore, when the user operates the switch 13 while the remote control of the lighting device 1 is disabled and changes the power supply state in the same pattern as the remote control disabled pattern, the control unit 2 may switch the remote control to enabled. Furthermore, the power supply state pattern that enables the remote control may be a pattern different from the remote control disabled pattern.

[0042] Through the above process, the user can disable remote control of the lighting device 1 by mechanically operating the switch 13, which is an operation unit. Remote control can also be disabled by changing the settings of the gateway device, which is a connection device that relays communication between the lighting control system and an external network, or by turning off the power to the gateway device. However, it is difficult for users who do not have knowledge about networks to operate the gateway device. In this embodiment, remote control can be disabled by operating the switch 13. Therefore, even users who do not have knowledge about networks can easily disable remote control if remote control creates an uncomfortable lighting environment for the user.

[0043] Many lighting devices 1 are installed on ceilings or walls. For example, even if the lighting device 1 is installed on a high ceiling and it is difficult for the user to directly touch the lighting device 1, the user can easily operate the operating unit by using a wall switch or a breaker switch 13 as the operating unit.

[0044] As described above, the lighting control system 100 of the present disclosure includes a lighting device having a light source unit 8, a communication unit 3 that communicates with a control server 400 that transmits control signals via an external network 300, and a control unit 2 that remotely controls the operation of the light source unit 8 based on control signals received from the control server 400, and an operation unit that receives mechanical operation by a user and disables the remote control. With this configuration, even a user who has no knowledge of networks can easily disable the remote control of the lighting device 1.

[0045] Furthermore, when remote control is disabled, the control unit performs local control to operate the light source unit based on a user's operation related to lighting control or an output value of a sensor. This allows lighting control system 100 to create an appropriate lighting environment for the user even when remote control is disabled.

[0046] Furthermore, the operation unit of lighting control system 100 is switch 13 that switches the power supply state to lighting device 1 between on and off by mechanical operation by the user, lighting device 1 further has power supply detection means that detects the power supply state to lighting device 1, and control unit 2 disables the remote control when the power supply state detected by the power supply detection means is performed in a preset pattern. In this way, by using switch 13, which is a wall switch or a breaker, as the operation unit, the user can easily operate the operation unit.

[0047] Furthermore, lighting control system 100 further includes a notification unit that notifies the user that remote control is disabled when remote control is disabled, thereby allowing the user to know whether remote control of lighting control system 100 is enabled or disabled.

[0048] Furthermore, when the remote control is disabled, the control unit 2 controls the light source unit to light up at a predetermined interval to notify the user that the remote control is disabled. This makes it possible to notify the user that the remote control of the illumination lighting device 1 is disabled without providing a display unit in the illumination lighting device 1.

[0049] Furthermore, when remote control is disabled, the user can enable remote control by operating the operation unit in lighting control system 100. This allows the user to easily enable remote control when they want to, improving convenience.

[0050] The illumination lighting device 1 of the present disclosure includes a light source unit 8, a communication unit 3 that communicates with an external network 300, a control unit 2 that remotely controls the light source unit 8 based on a control signal received by the communication unit 3 from the external network 300, and a power supply detection means that detects whether the power supply state to the illumination lighting device 1 is on or off, and the control unit 2 disables the remote control when the power supply state detected by the power supply detection means matches a preset pattern. With this configuration, even if it is difficult for a user to directly touch the illumination lighting device 1, the remote control of the illumination lighting device 1 can be easily disabled.

[0051] Furthermore, when the remote control is disabled, the control unit 2 of the illumination lighting device 1 enables the remote control if the power supply state recognized by the power supply recognition means is performed in a preset pattern. This allows the user to easily enable the remote control when they want to, improving convenience.

[0052] Embodiment 2 Next, a second embodiment will be described with reference to Fig. 5. Fig. 5 is a diagram showing an example of the configuration of a lighting control system 100 according to the second embodiment. In Fig. 5, parts that are the same as or correspond to those in Fig. 1 are given the same reference numerals. In this embodiment, a switch 11 is provided as an operation unit for cutting off communication on a communication cable that transmits signals from a connection device 50 to a dedicated network 10. An electric wire 15 that supplies power from an external power source 200 to the lighting device 1 and the sensor 12 is not shown in Fig. 5 because it is not related to the control in this embodiment. Note that a description of parts of this embodiment that are the same as those in the above-mentioned embodiments will be omitted.

[0053] In this embodiment, communication between the connection device 50 and the dedicated network 10 is performed using a communication cable such as a LAN cable, rather than wireless communication. As shown in FIG. 5 , a switch 11 is installed in the communication cable connecting the connection device 50 and the dedicated network 10. The switch 11 can be mechanically operated by a user, and when the switch 11 is closed, the communication cable between the connection device 50 and the dedicated network 10 is connected, allowing communication. When the switch 11 is in the off state, i.e., when the switch 11 is open, the communication cable between the connection device 50 and the dedicated network 10 is cut off, preventing communication. Furthermore, in order to stabilize the output to the dedicated network 10 when the switch 11 is in the off state, the communication cable may be branched between the switch 11 and the dedicated network 10 and connected to a GND potential. By providing a resistor 14 between the branch point of the communication cable and the GND potential, a signal from the connection device 50 flows through the communication cable when the switch 11 is in the on state.

[0054] Furthermore, the illumination lighting device 1 may determine that the remote control is disabled if the signal input from the connection device 50 is at GND potential for a certain period of time. When the illumination lighting device 1 determines that the remote control is disabled, it may blink the light source unit 8 several times. This allows the user to confirm that the remote control has been disabled by operating the switch 11.

[0055] Furthermore, to notify the user that the remote control is disabled, the lighting device 1 may blink the light source unit 8 several times at predetermined time intervals, for example, every hour. This allows the user to confirm whether the remote control of the lighting device 1 is enabled or disabled. Note that the control of the light source unit 8 to notify the user that the remote control is disabled is not limited to blinking several times at regular time intervals, but may also be predetermined lighting control, such as changing the dimming rate or color temperature at regular intervals.

[0056] As described above, by providing the switch 11, which switches between connecting and disconnecting communication, between the communication cable connecting the connection device 50 and the dedicated network 10, it is possible to block signals transmitted to the lighting device 1 via the external network 300. When the switch 11 is in the off state, control signals from the external network 300 are not transmitted to the lighting device 1, and remote control of the lighting device 1 is disabled. This has the effect that even a user who has no knowledge of networks can easily disable remote control if the remote control creates an uncomfortable lighting environment for the user.

[0057] Embodiment 3 Next, a third embodiment will be described with reference to Fig. 6. Fig. 6 is a diagram showing an example of the configuration of a lighting control system 100 according to the third embodiment. In Fig. 6, parts that are the same as or correspond to those in Fig. 1 are given the same reference numerals. In this embodiment, the connection device 50 has an operation unit that disables remote control of the lighting device 1. Note that a description of parts of this embodiment that are the same as those in the above-mentioned embodiments will be omitted.

[0058] The connection device 50 is a gateway device that connects the external network 300 with a dedicated network 10 that is made up of a plurality of illumination lighting devices 1 and sensors 12. In addition to the dedicated network 10, the connection device 50 also has a connection terminal 53 that connects a device (not shown) that has a communication function.

[0059] The connection device 50 includes a switch 51 that switches between connection and disconnection of communication between the external network 300 and the lighting control system 100, and a resistor 52 that is a pull-down resistor. The switch 51 is disposed exposed on the outside of the connection device 50 and can be mechanically operated by a user. The switch 51 may also be installed in a location away from the connection device 50, pulling out the communication cable inside the connection device 50. When the switch 51 is in the on state, i.e., when the switch 51 is closed, the external network 300 and the dedicated network 10 are connected and can communicate. When the switch 51 is in the off state, i.e., when the switch 51 is open, the signal output from the connection device 50 to the dedicated network 10 is fixed to the GND potential, and communication is disconnected.

[0060] When the switch 51 is in the off state, the output from the connection device 50 to the dedicated network 10 is fixed to the GND potential, and therefore, a control signal from the external network 300 is not transmitted to the light lighting device 1. Therefore, remote control of the light lighting device 1 is disabled, and the light lighting device 1 is controlled by local control.

[0061] Furthermore, the illumination lighting device 1 may determine that the remote control is disabled if the signal input from the connection device 50 is at GND potential for a certain period of time. When the illumination lighting device 1 determines that the remote control is disabled, it may blink the light source unit 8 several times. This allows the user to confirm that the remote control has been disabled by operating the switch 51.

[0062] Furthermore, to notify the user that the remote control is disabled, the lighting device 1 may blink the light source unit 8 several times at predetermined time intervals, for example, every hour. This allows the user to confirm whether the remote control of the lighting device 1 is enabled or disabled. Note that the control of the light source unit 8 to notify the user that the remote control is disabled is not limited to blinking several times at regular time intervals, but may also be predetermined lighting control, such as changing the dimming rate or color temperature at regular intervals.

[0063] As described above, the connection device 50 includes the switch 51 that can be mechanically operated by the user, and when the switch 51 is in the off state, control signals from the external network 300 are not transmitted to the lighting device 1, disabling remote control of the lighting device 1. The remote control of the lighting device 1 can also be disabled by turning off the power to the connection device 50. However, it is difficult for a user who is unfamiliar with networks to turn off the power to the connection device 50. By providing the connection device 50 with the switch 51 that can be mechanically operated by the user, even a user who is unfamiliar with networks can easily disable remote control if the remote control creates an uncomfortable lighting environment for the user.

[0064] Furthermore, when the power supply to the connection device 50 is cut off, communication between devices other than the dedicated network 10 connected to the connection device 50 and the external network 300 is cut off. By turning off the switch 51 of the connection device 50 and cutting off communication between the dedicated network 10 and the external network 300, it is possible to achieve the effect of not interfering with communication with devices other than the dedicated network 10.

[0065] Furthermore, the lighting device 1 may be controlled to turn on the light source unit 8 when it detects that communication from the external network 300 has been fixed at GND potential for a certain period of time. When the switch 51 is turned off and remote control of the lighting device 1 is disabled, the lighting environment may become dark with the lighting device 1 turned off, which may cause inconvenience to the user. Therefore, as a fail-safe operation, when remote control is disabled, the lighting device 1 is turned on to provide a safe lighting environment for the user.

[0066] Furthermore, even if the communication between the connection device 50 and the dedicated network 10 is wireless, the communication can be cut off by providing a switch 51 that cuts off the signal before it is input to the wireless transmission circuit.

[0067] As described above, the lighting control system 100 of the present disclosure includes a lighting device having a light source unit 8, a communication unit 3 that communicates with an external network 300, a control unit 2 that operates the light source unit 8 by remote control based on control signals received by the communication unit 3 from the external network 300 and by local control based on user operation or output values of various sensors, an operation unit that disables the remote control when the user performs a mechanical operation, and a connection device 50 that relays communication between the external network 300 and the communication unit 3 of the lighting device 1, and the user disables the remote control by operating the operation unit to cut off communication between the connection device 50 and the communication unit 3 of the lighting device 1. With this configuration, even a user who has no knowledge of networks can easily disable the remote control of the lighting device 1.

[0068] Embodiment 4 Next, a fourth embodiment will be described with reference to Figs. 7 and 8. Fig. 7 is a diagram showing an example of the configuration of a lighting control system 100 according to the fourth embodiment. In Fig. 7, parts that are the same as or correspond to those in Fig. 1 are given the same reference numerals. In this embodiment, the lighting control system 100 includes a relay device 60 for connecting the connection device 50 to the dedicated network 10. The relay device 60 includes an operation unit that disables remote control of the lighting device 1. Fig. 8 is a schematic diagram showing the configuration of the relay device 60 according to the fourth embodiment. Note that a description of parts of this embodiment that are the same as those in the above-mentioned embodiments will be omitted.

[0069] The relay device 60 relays communication between the connection device 50 and the dedicated network 10. The light lighting devices 1 and the sensors 12 are connected to the relay device 60 by wire or wirelessly. As shown in FIG. 7 , there may be a plurality of relay devices 60 in the lighting control system 100. One relay device 60 and the light lighting devices 1 and sensors 12 connected to the relay device 60 constitute one control group. In this embodiment, remote control can be enabled or disabled for each relay device 60.

[0070] The relay device 60 includes a switch 61 that switches between connection and disconnection of communication between the external network 300 and the dedicated network 10, a resistor 62 that is a pull-down resistor, and a buffer 63. The switch 61 is disposed exposed on the outside of the relay device 60 and can be mechanically operated by a user. The switch 61 may also be installed in a location away from the relay device 60, pulling out a communication cable inside the relay device 60. When the switch 61 is in the on state, i.e., when the switch 61 is closed, communication between the external network 300 and the dedicated network 10 is possible. When the switch 61 is in the off state, i.e., when the switch 61 is open, a signal output from the relay device 60 to the dedicated network 10 is fixed to the GND potential. Note that the relay device 60 includes a buffer 63 before the connection point with the GND potential, so that the signal line on the connection device 50 side of the relay device 60 is not fixed to the GND potential even when the switch 61 is closed.

[0071] When the switch 61 is in the off state, the output from the relay device 60 to the dedicated network 10 is fixed to the GND potential, and therefore, a control signal from the external network 300 is not transmitted to the lighting device 1. Therefore, remote control of the lighting device 1 is disabled, and the lighting device 1 is controlled by local control.

[0072] Furthermore, the illumination lighting device 1 may determine that remote control is disabled if the signal input from the relay device 60 is at GND potential for a certain period of time. When the illumination lighting device 1 determines that remote control is disabled, it may blink the light source unit 8 several times. This allows the user to confirm that remote control has been disabled by operating the switch 61.

[0073] Furthermore, to notify the user that the remote control is disabled, the lighting device 1 may blink the light source unit 8 several times at predetermined time intervals, for example, every hour. This allows the user to confirm whether the remote control of the lighting device 1 is enabled or disabled. Note that the control of the light source unit 8 to notify the user that the remote control is disabled is not limited to blinking several times at regular time intervals, but may also be predetermined lighting control, such as changing the dimming rate or color temperature at regular intervals.

[0074] As described above, the relay device 60 is provided with the switch 61 that can be mechanically operated by the user, and when the switch 61 is in the off state, remote control of the lighting device 1 is disabled. Even if the power supply to the relay device 60 is cut off, the remote control of the lighting device 1 can be disabled. However, it is difficult for a user who has no knowledge about networks to cut off the power supply to the relay device 60. By providing the relay device 60 with the switch 61 that can be mechanically operated by the user, even a user who has no knowledge about networks can easily disable the remote control if the remote control creates an uncomfortable lighting environment for the user.

[0075] Furthermore, by cutting off communication between the relay device 60 and the dedicated network 10, it is possible to effectively disable the remote control of only the illumination lighting device 1 connected to the relay device 60 whose communication has been cut off.

[0076] Furthermore, the lighting device 1 may be controlled to turn on the light source unit 8 when it detects that communication from the external network 300 has been fixed at GND potential for a certain period of time. When the switch 61 is turned off and remote control of the lighting device 1 is disabled, the lighting environment may become dark with the lighting device 1 turned off, which may cause inconvenience to the user. Therefore, as a fail-safe operation, when remote control is disabled, the lighting device 1 is turned on to provide a safe lighting environment for the user.

[0077] As described above, the lighting control system 100 of the present disclosure includes a lighting device having a light source unit 8, a communication unit 3 that communicates with an external network 300, a control unit 2 that operates the light source unit 8 by remote control based on control signals received by the communication unit 3 from the external network 300 and by local control based on user operation or output values of various sensors, an operation unit that disables the remote control when the user performs a mechanical operation, and at least one relay device 60 to which the lighting device 1 is connected wirelessly or wired and that relays communication between the external network 300 and the communication unit of the lighting device 1, and the user disables the remote control by operating the operation unit to block signals transmitted by the relay device. With this configuration, even a user who has no knowledge of networks can easily disable the remote control of the lighting device 1.

[0078] The configurations shown in the above embodiments are examples of the content of the present invention, and may be combined with other known technologies, and some of the configurations may be omitted or modified within the scope of the gist of the present invention.
