[0007] The lighting control method will be described below with reference to the drawings. First, the configuration of a lighting control system 1000 will be described with reference to FIG.
[0008] As shown in FIG. 1, the lighting control system 1000 includes a smartphone 100 as an information processing device, a projector 200 as a display device, and a lighting device 300 as a lighting fixture.
[0009] Even if the smartphone 100 does not support the control protocol standard of the lighting device 300, the lighting control system 1000 can associate the smartphone 100 with the lighting device 300 via the projector 200. In other words, for example, by operating the smartphone 100, the lighting device 300 can be turned on or off, or the color or brightness of the lighting device 300 can be changed.
[0010] The projector 200 includes a projection unit 250 for projecting image information input from the outside onto a projection surface 400. A projection image 410 based on the image information is displayed on the projection surface 400. Examples of the projection surface 400 include a wall in a room, a screen, and a whiteboard.
[0011] Next, the electrical configuration of the lighting control system 1000 will be described with reference to FIG.
[0012] As shown in FIG. 2, the lighting control system 1000 includes the smartphone 100, the projector 200, and the lighting device 300, as described above.
[0013] The smartphone 100 includes a control unit 110 , an imaging unit 120 , a communication unit 130 , a storage unit 140 , a display unit 150 , and a selection unit 160 .
[0014] The control unit 110 is configured to include one or more processors, and operates in accordance with a control program stored in the storage unit 140 to perform overall control of the operation of the smartphone 100 .
[0015] The imaging unit 120 captures an image of the identification code attached to the lighting device 300. The imaging unit 120 may be, for example, a camera equipped with a CCD (Charge Coupled Device) sensor or a CMOS (Complementary Metal Oxide Semiconductor) sensor. The identification code may be, for example, a QR code 310 or a barcode.
[0016] The communication unit 130 transmits and receives signals to and from the communication unit 220 of the projector 200. The communication unit 130 is, for example, a short-range wireless communication unit such as Bluetooth (registered trademark).
[0017] The storage unit 140 is configured to include memories such as a RAM (Random Access Memory) and a ROM (Read Only Memory). The RAM is used for temporary storage of various data, and the ROM stores control programs and control data for controlling the operation of the smartphone 100.
[0018] The display unit 150 includes a display panel such as an LCD (liquid crystal display), and displays, for example, the communication status with the projector 200.
[0019] The selection unit 160 selects, for example, whether to turn the lighting device 300 on or off, whether to brighten or darken the brightness of the lighting device 300, what color to display, and the like.
[0020] The projector 200 includes a control unit 210, a communication unit 220, a projection unit 250, a storage unit 230, and a processing unit 240.
[0021] The control unit 210 is configured to include one or more processors, and operates in accordance with a control program stored in the storage unit 230 to perform overall control of the operation of the projector 200 .
[0022] The communication unit 220 transmits and receives signals to and from the communication unit 130 of the smartphone 100 and the communication unit 340 of the lighting device 300. The communication unit 220 is, for example, a short-range wireless communication unit such as Bluetooth.
[0023] The storage unit 230 is configured to include memories such as RAM (Random Access Memory) and ROM (Read Only Memory). The RAM is used for temporary storage of various data, and the ROM stores control programs and control data for controlling the operation of the projector 200.
[0024] The processing unit 240 executes each process based on instructions from the control unit 210.
[0025] Although not shown, the projection unit 250 is configured to include a light source, a liquid crystal light valve as a light modulation device, a projection optical system, a light valve driving unit, etc. The projection unit 250 modulates light emitted from the light source with the liquid crystal light valve to form image light, and projects this image light from the projection optical system which includes at least one of a lens and a mirror to display a projection image 410 on the projection surface 400.
[0026] The lighting device 300 includes a QR code 310, a control unit 320, a storage unit 330, a communication unit 340, and a display unit 350.
[0027] The QR code 310 is provided on the lighting device 300. The QR code 310 is a two-dimensional code. The QR code 310 is attached to the lighting device 300 at a position where an image of the QR code 310 can be captured by the smartphone 100.
[0028] The control unit 320 is configured to include one or more processors, and operates in accordance with a control program stored in the storage unit 330 to comprehensively control the operation of the lighting device 300 .
[0029] The storage unit 330 is configured to include memories such as RAM (Random Access Memory) and ROM (Read Only Memory). The RAM is used to temporarily store various data, and the ROM stores control programs and control data for controlling the operation of the lighting device 300.
[0030] The communication unit 340 transmits and receives signals to and from the communication unit 220 of the projector 200. The communication unit 340 is, for example, a short-range wireless communication unit such as Bluetooth.
[0031] The display unit 350 is a light-emitting device that changes color, brightness, etc. based on light-emitting data. The display unit 350 has light-emitting elements such as LEDs (Light Emitting Diodes). For example, the display unit 350 preferably has one or more red LEDs that emit red light, one or more green LEDs that emit green light, and one or more blue LEDs that emit blue light.
[0032] Next, a lighting control method of the lighting control system 1000 will be described with reference to FIGS.
[0033] As shown in FIG. 3, in step S11, the smartphone 100 scans the QR code 310. Note that the smartphone 100 and the projector 200 have been paired in advance. Specifically, as shown in FIG. 4, the user brings the smartphone 100 close to the QR code 310 attached to the lighting device 300 and scans the QR code 310. This enables the smartphone 100 to read an identification code based on the QR code 310. The control unit 110 of the smartphone 100 stores the read identification code in the storage unit 140.
[0034] Next, in step S12, the information of the QR code 310 is transmitted to the projector 200. Specifically, as shown in Fig. 5, the control unit 110 of the smartphone 100 causes the communication unit 130 to transmit the identification code to the communication unit 220 of the projector 200. The control unit 210 of the projector 200 causes the storage unit 230 to store the identification code received via the communication unit 220.
[0035] Next, in step S13, the Matter device is registered based on the information in the QR code 310. The Matter device is the lighting device 300. Matter is one of the control protocols. The projector 200 is paired with the lighting device 300 based on the identification code stored in the storage unit 230.
[0036] Next, in step S14, a completion notification is sent to smartphone 100. Specifically, as shown in Fig. 6, control unit 210 of projector 200 causes communication unit 220 to send a pairing completion signal indicating that pairing with lighting device 300 has been completed to communication unit 130 of smartphone 100. As a result, display unit 150 of smartphone 100 displays a message indicating that pairing between projector 200 and lighting device 300 has been completed.
[0037] In this way, the projector 200 and the lighting device 300 are paired based on the identification code, so even if the smartphone 100 does not support the control protocol standard of the lighting device 300, the lighting device 300 and the smartphone 100 can be associated with each other via the projector 200. In other words, the lighting device 300 can be operated in response to the operation of the smartphone 100. This completes the device registration.
[0038] Next, a method for controlling the lighting device 300 will be described. In step S15, the smartphone 100 transmits a control signal to the projector 200. Specifically, as shown in FIG. 7 , the control unit 110 of the smartphone 100 transmits a control signal for controlling the lighting device 300 to the communication unit 220 of the projector 200 via the communication unit 130. Examples of the control signal include a signal for turning the power of the lighting device 300 on or off, a signal for the brightness of the display unit 350, a signal for the color of the display unit 350, and a signal for the lighting time or blinking time of the display unit 350.
[0039] Next, in step S16, a control signal is transmitted from the projector 200 to the lighting device 300. Specifically, as shown in Fig. 8, the control unit 210 of the projector 200 transmits the control signal received by the communication unit 220 to the communication unit 340 of the lighting device 300. In other words, an instruction from the smartphone 100, i.e., a control signal, is transmitted to the lighting device 300 via the projector 200.
[0040] Next, in step S17, processing is performed based on the control signal. Specifically, as shown in Fig. 9, the control unit 320 of the lighting device 300 causes the display unit 350 to perform processing based on the received control signal. Note that, as the processing in this embodiment, for example, the display unit 350 of the lighting device 300 is turned on.
[0041] Next, in step S18, a completion notification is sent to smartphone 100. Specifically, as shown in Fig. 9, control unit 210 of projector 200 causes communication unit 220 to send a completion signal indicating that execution of the process has been completed to communication unit 130 of smartphone 100. Display unit 150 of smartphone 100 displays a message indicating that display unit 350 of lighting device 300 has been turned on.
[0042] In this way, even if the smartphone 100 does not support the control protocol standard of the lighting device 300, the lighting device 300 can be operated from the smartphone 100 via the projector 200. In this way, the control of the lighting device 300 is completed.
[0043] As described above, the lighting control method of this embodiment includes the steps of pairing the smartphone 100 with the projector 200, the smartphone 100 reading the QR code 310 attached to the lighting device 300, the smartphone 100 transmitting the QR code 310 to the projector 200, the projector 200 pairing with the lighting device 300 based on the QR code 310, and the projector 200 transmitting a pairing completion signal to the smartphone 100.
[0044] According to this method, the projector 200 and the lighting device 300 are paired based on the QR code 310, so even if the smartphone 100 does not support the control protocol standard (e.g., Matter) of the lighting device 300, the lighting device 300 and the smartphone 100 can be associated with each other via the projector 200. In other words, the user can control the lighting device 300 by operating the smartphone 100.
[0045] Furthermore, the lighting control method of this embodiment preferably includes the steps of: smartphone 100 transmitting a control signal for controlling lighting device 300 to projector 200; projector 200 transmitting the control signal to lighting device 300; and lighting device 300 executing predetermined control based on the control instruction of the control signal. According to this method, projector 200 and lighting device 300 are paired based on QR code 310. Therefore, even if smartphone 100 does not support the control protocol standard of lighting device 300, lighting device 300 and smartphone 100 can be associated with each other via projector 200. That is, the user can control lighting device 300 by operating smartphone 100.
[0046] Modifications of the above-described embodiment will now be described.
[0047] As described above, the control is not limited to the lighting device 300 on the left side of the projection surface 400, but the lighting device on the right side may also be controlled. In the case of controlling the lighting device on the right side, the QR code of the lighting device on the right side is scanned in the same manner.
[0048] As described above, the control protocol is not limited to Matter, and any other control protocol may be used as long as it is a common standard.
[0049] The following is a summary of this disclosure. (Supplementary Note 1) A lighting control method including: pairing an information processing device with a display device; reading an identification code attached to a lighting fixture by the information processing device; transmitting the identification code by the information processing device to the display device; pairing the display device with the lighting fixture based on the identification code; and transmitting a pairing completion signal by the display device to the information processing device.
[0050] According to this method, since the display device and the lighting fixture are paired based on the identification code, even if the information processing device does not support the control protocol standard of the lighting fixture (e.g., Matter), the lighting fixture and the information processing device can be associated via the display device. In other words, the lighting fixture can be controlled in response to the operation of the information processing device.

According to this method, the display device and the luminaire are paired based on an identification code, so that even if the information processing device does not support the control protocol standard of the luminaire, the luminaire and the information processing device can be associated via the display device. In other words, the luminaire can be controlled in accordance with the operation of the information processing device. [Explanation of symbols]
