Mode for Carrying Out the Invention

[0010] Embodiment 1 FIG. 1 is a diagram showing the configuration of the lighting system according to Embodiment 1 of the present disclosure. The lighting system 1000 includes a lighting fixture 100. The lighting fixture 100 can perform wireless communication with a cloud server 300 via a router 200. The router 200 is, for example, a wireless LAN router. The cloud server 300 is connected to a terminal 400 having a display unit by wireless communication or wired communication.

[0011] As described above, the lighting fixture 100 and the terminal 400 can communicate via the router 200 and the cloud server 300. That is, the lighting system 1000 is a system that can perform lighting control of the lighting fixture 100 by remote operation when the user operates the terminal 400.

[0012] FIG. 2 is a diagram showing the configuration of the lighting fixture according to Embodiment 1 of the present disclosure. The lighting fixture 100 includes a receiving unit 160 that can transmit and receive information with the router 200. The receiving unit 160 receives a wireless signal transmitted from the router 200 and transmits it to the signal processing unit 150. This wireless signal is, for example, a dimming instruction transmitted from the terminal 400 by a user operation. This dimming instruction may include information on the lighting fixture that is the target of the dimming instruction.

[0013] The signal processing unit 150 transmits the instruction information obtained by processing the received radio signal to the control unit 130. This instruction information includes the dimming instruction and information on the lighting fixture that is the target of the dimming instruction.

[0014] The lighting fixture 100 also includes a human detection unit 140. The human detection unit 140 has a function of detecting the presence or absence of a person in the area where the lighting fixture 100 is installed, and transmits the detection result to the control unit 130.

[0015] Based on the received instruction information and the detection result, the control unit 130 determines whether to perform a remote operation based on the received instruction information. The details of the determination method will be described later.

[0016] Note that the function of the human detection unit 140 for detecting the presence or absence of a person is preferably a function of detecting a stationary person by image recognition using a camera or the like, or a function of detecting with a pyroelectric sensor. Alternatively, it may be a function of detecting with a radio wave sensor or the like.

[0017] When performing a remote operation, the control unit 130 transmits the instruction information to the lighting control unit 120. The lighting control unit 120 performs lighting control of the light source 110 based on the instruction information from the control unit 130. The light source 110 is a light source composed of at least one light emitting element. When not performing a remote operation, the control unit 130 discards the instruction information.

[0018] Although illustration is omitted, regarding the first hardware configuration of the lighting fixture according to Embodiment 1 of the present disclosure, for example, the light source 110 includes a light emitting element, the lighting control unit 120 is a lighting control circuit, and the control unit 130 is a control circuit. Also, for example, the human detection unit 140 can use a pyroelectric sensor, the signal processing unit 150 is a signal processing circuit, and the receiving unit 160 is an antenna. In this way, the functions of the lighting control unit 120, the control unit 130, and the signal processing unit 150 in the lighting fixture may be respectively realized by dedicated hardware, namely, a lighting control circuit, a control circuit, and a signal processing circuit.

[0019] Furthermore, although illustration is omitted, regarding the second hardware configuration of the lighting fixture according to Embodiment 1 of the present disclosure, the functions of the lighting control unit 120, the control unit 130, and the signal processing unit 150 in the lighting fixture 100 may be realized by, for example, a CPU 180 that executes a program stored in a memory 190.

[0020] Figure 3 is a flowchart showing a method for determining whether to perform remote control according to Embodiment 1 of the present disclosure. This determination is started by using, as a trigger, a dimming instruction transmitted from the terminal 400 to the lighting fixture 100 by a user operation.

[0021] First, in step S100, the lighting fixture 100 determines whether to enable or disable remote control by determining whether the dimming instruction is addressed to itself. Specifically, the control unit 130 determines whether the dimming instruction is addressed to itself by referring to the lighting fixture information included in the instruction information. If it is determined that the instruction is addressed to itself, the remote control is enabled and the process proceeds to step S102. If it is determined that the instruction is not addressed to itself, the remote control is disabled and the process proceeds to step S110.

[0022] In step S102, the lighting fixture 100 determines whether there is a person in its control area. Specifically, the control unit 130 makes a determination based on the detection result described above. If it is determined that there is no person, the process proceeds to step S104. If it is determined that there is a person, the process proceeds to step S112.

[0023] In step S104, the lighting fixture 100 performs lighting control of the light source 110. Specifically, first, the control unit 130 determines to enable remote control and transmits the instruction information including the dimming instruction to the lighting control unit 120. The lighting control unit 120 performs lighting control of the light source 110 based on the received instruction information. This lighting control may be a lighting and extinguishing operation or a dimming operation.

[0024] Next, in step S106, the lighting fixture 100 transmits success information to the terminal 400. The success information is information for notifying that the lighting control of the lighting fixture 100 has been completed as per the dimming instruction.

[0025] Next, in step S108, the terminal 400 that has received the success information displays a process completion indication on the display unit. Through this display, the user can confirm that the dimming instruction has been successful.

[0026] In step S110, the terminal 400 displays an indication of uncontrollability on the display unit. Specifically, the control unit 130 determines to invalidate the remote operation and discards the dimming instruction. Also, the control unit 130 transmits the determination result to the terminal 400. The terminal 400 displays an indication of uncontrollability on the display unit based on the determination result. Through this display, the user can confirm that the lighting fixture 100 is in an uncontrollable state and that the dimming instruction has failed.

[0027] In step S112, the terminal 400 displays an indication of uncontrollability on the display unit. Specifically, the control unit 130 that has determined that there is a person discards the dimming instruction. Also, the control unit 130 transmits the determination result to the terminal 400. The terminal 400 displays an indication of uncontrollability on the display unit based on the determination result. Through this display, the user can confirm that the dimming instruction has failed because there is a person in the control area of the lighting fixture 100.

[0028] As described above, according to the present embodiment, lighting control by remote operation is performed only when there is no person in the area where the lighting fixture to be controlled is installed. That is, it is possible to provide a lighting system in which lighting control contrary to the intention of the person staying in the area where the lighting fixture is installed is not performed.

[0029] Embodiment 2 FIG. 4 is a diagram showing the configuration of a lighting system according to Embodiment 2 of the present disclosure. This embodiment is different from Embodiment 1 in that it includes a switch 500 having a function of detecting the presence or absence of a person.

[0030] The lighting system 2000 includes a switch 500. When directly operated by a user, the switch 500 has a function of controlling the lighting of the lighting fixture 100a of the present embodiment. This lighting control may be the on / off switching of the lighting fixture 100a, or the change of the dimming rate or color temperature. The switch 500 may be, for example, a push-button type or a liquid crystal type.

[0031] Furthermore, the switch 500 of the present embodiment has a function of detecting the presence or absence of a person in the area where the lighting fixture 100a is installed, and transmits the detection result to the lighting fixture 100a. The function of detecting the presence or absence of a person that the switch 500 has is preferably a function of detecting a stationary person by image recognition using a camera or the like, or a function of detecting with a radio wave sensor. Alternatively, it may be a function of detecting with a pyroelectric sensor or the like.

[0032] The function of detecting the presence or absence of a person will be described in more detail. As sensors used for human detection, pyroelectric sensors or radio wave sensors are known. Pyroelectric sensors are suitable for detecting in the crossing direction, and radio wave sensors are suitable for detecting approaching and receding movements. Therefore, it is more appropriate for the lighting fixture 100 installed on the ceiling to have a pyroelectric sensor and the switch 500 installed on the wall surface to have a radio wave sensor to perform appropriate human detection.

[0033] A pyroelectric sensor detects the presence or absence of a person based on the temperature difference between the ambient temperature and the moving body. Therefore, in an environment where the temperature difference between the ambient temperature and a person as a moving body is small, such as in summer, it may be difficult to detect the presence or absence of a person. On the other hand, since a radio wave sensor detects the presence or absence of a person by radio waves, it is not difficult to detect the presence or absence of a person due to the influence of the ambient temperature.

[0034] In the present embodiment, since the switch 500 has a function of detecting the presence or absence of a person, it is preferable to use a radio wave sensor. Therefore, in the present embodiment, the presence or absence of a person can be detected without being affected by the ambient temperature.

[0035] Moreover, pyroelectric sensors and radio wave sensors also differ in terms of design. Since pyroelectric sensors often have a lens-shaped form, they may be mistaken by users for surveillance cameras and be shunned. On the other hand, since radio wave sensors often have a flat and thin form, they are not shunned by users visually. Furthermore, since radio waves can pass through resin, the radio wave sensor may be incorporated, for example, in a plastic switch 500. In this case, the radio wave sensor can function without being noticed by the user.

[0036] FIG. 5 is a diagram showing the configuration of a lighting fixture according to Embodiment 2 of the present disclosure. The lighting fixture 100a of the present embodiment differs from the lighting fixture 100 in that it includes a receiving unit 161 and a human detection unit 140a that does not have a function of detecting the presence or absence of a person.

[0037] The lighting fixture 100a includes a receiving unit 161 that can receive information from the switch 500. For example, the receiving unit 161 receives the detection result transmitted from the switch 500 and transmits it to the human detection unit 140a. The human detection unit 140a manages the received detection result and transmits it to the control unit 130 as necessary. The control unit 130 determines whether to perform a remote operation based on the received instruction information based on the received detection result.

[0038] The determination method is the same as that of Embodiment 1 except that the switch 500 detects the presence or absence of a person. That is, in step S102 of FIG. 3, it is the same as Embodiment 1 except that the detection result used by the control unit 130 for determination is the detection result detected by the switch 500.

[0039] As described above, according to the present embodiment, lighting control by remote operation is performed only when there is no person in the area where the lighting fixture to be controlled is installed. That is, it is possible to provide a lighting system in which lighting control against the intention of a person staying in the area where the lighting fixture is installed is not performed. Furthermore, since the switch 500 has a function of detecting the presence or absence of a person, it is not affected by the ambient temperature and can detect the presence or absence of a person without being noticed by the user.

[0040] Embodiment 3 FIG. 6 is a diagram showing the configuration of the lighting system according to Embodiment 3 of the present disclosure. This embodiment is different from Embodiment 2 in that it includes a terminal 401 capable of directly communicating with the lighting fixture 100a and has a function of switching between enabling and disabling remote control.

[0041] The lighting system 3000 includes a terminal 401. The terminal 401 is a terminal capable of communicating with the lighting fixture 100a, for example, via Bluetooth (registered trademark). The terminal 401 has a function of controlling the lighting of the lighting fixture 100a of this embodiment when operated by the user. This lighting control may be switching on / off the lighting fixture 100a, or changing the dimming rate or color temperature.

[0042] Also, a fade time may be provided for the above-described on / off switching. Thereby, the on / off switching can be performed without rapidly changing the light source 110, so that it is possible to avoid the user from being confused or falling into an unsafe situation. Further, the user may be able to set the fade time via the terminal 401.

[0043] Furthermore, when the lighting fixture 100a of this embodiment is paired with the terminal 401, it may be configured not to receive a remote operation from another terminal 400 outside the communication range.

[0044] The lighting system 3000 also includes a switch 500a. The switch 500a has a function of switching between enabling and disabling remote control in addition to the function of the switch 500. That is, when the user performs an operation to switch between enabling and disabling remote control, the switch 500a transmits the switching result to the lighting fixture 100a via the receiving unit 161.

[0045] As described above, since the lighting system 3000 has a function of switching between enabling and disabling remote operation, the remote operation in an area without people can be temporarily restricted. For example, for an area where people are not present for a long time, such as at night, the unnecessary costs generated by accidentally performing unnecessary lighting control can be reduced.

[0046] Here, although the mode in which the switch 500a has the function of switching between enabling and disabling remote operation is shown, the terminal 401 may have it. Also, the time zone for switching between enabling and disabling remote operation may be set in advance and automatically switched to temporarily restrict the remote operation in an area without people. In this case, the user may set the time zone for switching between enabling and disabling remote operation via the terminal 401.

[0047] FIG. 7 is a flowchart showing a method for determining whether to perform remote operation according to Embodiment 3 of the present disclosure. Note that the description of steps common to the flowchart of FIG. 3 is omitted.

[0048] First, in step S114, the lighting fixture 100a determines whether the remote operation is enabled, thereby determining whether to enable or disable the remote operation. Specifically, the control unit 130 determines based on the above-described switching result. If it is determined to be enabled, the process proceeds to step S102. If it is determined not to be enabled, the process proceeds to step S116.

[0049] In step S116, the terminal 400 displays an indication of uncontrollability on the display unit. Specifically, first, the control unit 130 that has determined that the remote operation is not enabled discards the dimming instruction. Also, the control unit 130 transmits the determination result to the terminal 400. The terminal 400 displays an indication of uncontrollability on the display unit based on the determination result. By this display, the user can confirm that the remote operation of the lighting fixture 100a is not enabled and that the dimming instruction has failed.

[0050] As described above, according to the present embodiment, lighting control by remote operation is performed only when there is no person in the area where the lighting fixture to be controlled is installed. That is, it is possible to provide a lighting system in which lighting control against the intention of a person staying in the area where the lighting fixture is installed is not performed. Further, since the lighting system has a function of switching between enabling and disabling remote operation, remote operation in an area where there is no person can be temporarily restricted.
