Detailed Implementation

[0017] The lighting control method will now be described with reference to the accompanying drawings. First, refer to... Figure 1 Explain the structure of the lighting control system 1000.

[0018] like Figure 1 As shown, 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 lamp.

[0019] Even if the smartphone 100 does not conform to the control protocol standard of the lighting device 300, the lighting control system 1000 can still establish a correspondence between the smartphone 100 and the lighting device 300 via the projector 200. In other words, for example, the smartphone 100 can be used to turn the lighting device 300 on or off, or to change the color or brightness of the lighting device 300.

[0020] The projector 200 has a projection unit 250 for projecting externally input image information, etc., onto a projection surface 400. A projected image 410 based on the image information is displayed on the projection surface 400. Examples of projection surfaces 400 include room walls, screens, whiteboards, etc.

[0021] Next, refer to Figure 2 Describe the electrical structure of the lighting control system 1000.

[0022] like Figure 2 As shown above, the lighting control system 1000 includes a smartphone 100, a projector 200, and a lighting device 300.

[0023] The smartphone 100 has a control unit 110, a camera unit 120, a communication unit 130, a storage unit 140, a display unit 150, and a selection unit 160.

[0024] The control unit 110 is configured to have one or more processors, and controls the operation of the smartphone 100 in a unified manner by performing operations according to the control program stored in the storage unit 140.

[0025] The identification code is provided by the imaging unit 120 and the imaging illumination device 300. Examples of imaging units 120 include cameras equipped with CCD (Charge Coupled Device) sensors and CMOS (Complementary Metal Oxide Semiconductor) sensors. Examples of identification codes include QR codes 310 and barcodes.

[0026] The communication unit 130 transmits and receives signals with the communication unit 220 of the projector 200. The communication unit 130 is, for example, a short-range wireless communication such as Bluetooth (registered trademark).

[0027] The storage unit 140 is configured to include RAM (Random Access Memory) and ROM (Read Only Memory). RAM is used for temporary storage of various data, while ROM stores control programs and control data used to control the operation of the smartphone 100.

[0028] The display unit 150 has, for example, a display panel such as an LCD (liquid crystal display) to display, for example, the communication status with the projector 200.

[0029] The selection unit 160 allows users to select, for example, whether to turn the lighting device 300 on or off, whether to brighten or dim the lighting device 300, and what color to display.

[0030] 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.

[0031] The control unit 210 is configured to have one or more processors, and controls the operation of the projector 200 in a unified manner by performing operations according to the control program stored in the storage unit 230.

[0032] The communication unit 220 transmits and receives signals between itself and the communication unit 130 of the smartphone 100, and between itself and the communication unit 340 of the lighting device 300. The communication unit 220 is, for example, a short-range wireless communication such as Bluetooth.

[0033] The storage unit 230 is configured to include RAM (Random Access Memory) and ROM (Read Only Memory). RAM is used for temporary storage of various data, and ROM stores control programs and control data used to control the operation of the projector 200.

[0034] The processing unit 240 executes each process based on the instructions of the control unit 210.

[0035] 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, and a light valve drive unit. The projection unit 250 uses the liquid crystal light valve to modulate the light emitted from the light source to form image light, and projects the image light from the projection optical system including at least one of a lens and a mirror to display the projected image 410 on the projection surface 400.

[0036] The lighting device 300 includes a QR code 310, a control unit 320, a storage unit 330, a communication unit 340, and a light-emitting unit 350.

[0037] QR code 310 is equipped on the lighting device 300. QR code 310 is a two-dimensional code. QR code 310 is installed on a part of the lighting device 300 that can be photographed by a smartphone 100.

[0038] The control unit 320 is configured to have one or more processors, and to uniformly control the operation of the lighting device 300 by performing operations according to the control program stored in the storage unit 330.

[0039] The storage unit 330 is configured to include RAM (Random Access Memory) and ROM (Read Only Memory). RAM is used for temporary storage of various data, and ROM stores control programs and control data used to control the operation of the lighting device 300.

[0040] The communication unit 340 transmits and receives signals with the communication unit 220 of the projector 200. The communication unit 340 is, for example, a short-range wireless communication such as Bluetooth.

[0041] The light-emitting part 350 is a light-emitting device whose color, brightness, and other properties change based on light-emitting data. The light-emitting part 350 may include, for example, a light-emitting element such as an LED (Light Emitting Diode). For example, the light-emitting part 350 preferably has one or more red LEDs that emit red light, green LEDs that emit green light, and blue LEDs that emit blue light.

[0042] Next, refer to Figures 3-9Explain the lighting control method of the lighting control system 1000.

[0043] like Figure 3 As shown, in step S11, the smartphone 100 scans the QR code 310. Furthermore, the smartphone 100 is pre-paired with the projector 200. Specifically, as... Figure 4 As shown, the user brings the smartphone 100 close to the QR code 310 installed on the lighting device 300 and scans the QR code 310. The smartphone 100 is then able to read the 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.

[0044] Next, in step S12, the information of QR code 310 is sent to projector 200. Specifically, as follows... Figure 5 As shown, the control unit 110 of the smartphone 100 causes the communication unit 130 to send 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.

[0045] Next, in step S13, the Matter device is registered based on the information in QR code 310. The Matter device is the lighting device 300. Matter is one of the control protocols. The projector 200 pairs with the lighting device 300 based on the identification code stored in the storage unit 230.

[0046] Next, in step S14, a completion notification is sent to the smartphone 100. Specifically, as follows: Figure 6 As shown, the control unit 210 of the projector 200 causes the communication unit 220 to send a pairing completion signal to the communication unit 130 of the smartphone 100, indicating that pairing with the lighting device 300 has been completed. Consequently, a message indicating that pairing between the projector 200 and the lighting device 300 is complete is displayed on the display unit 150 of the smartphone 100.

[0047] In this way, the projector 200 and the lighting device 300 are paired based on an identification code. Therefore, even if the smartphone 100 does not conform to the control protocol standard of the lighting device 300, a correspondence can still be established between the lighting device 300 and the smartphone 100 via the projector 200. That is, the lighting device 300 can be activated based on the operation of the smartphone 100. Through the above, the device registration is completed.

[0048] Next, the control method for the lighting device 300 will be described. In step S15, a control signal is sent from the smartphone 100 to the projector 200. Specifically, as follows... Figure 7As shown, the control unit 110 of the smartphone 100 causes the communication unit 130 to send control signals for controlling the lighting device 300 to the communication unit 220 of the projector 200. Examples of control signals include signals for turning the power on or off the lighting device 300, signals for the brightness of the light-emitting part 350, signals for the color of the light-emitting part 350, signals for the lighting time of the light-emitting part 350, and signals for the flashing time of the light-emitting part 350.

[0049] Next, in step S16, a control signal is sent from the projector 200 to the lighting device 300. Specifically, as follows: Figure 8 As shown, the control unit 210 of the projector 200 causes the communication unit 220 to send the received control signal to the communication unit 340 of the lighting device 300. That is, the instructions, i.e., control signals, of the smartphone 100 are sent to the lighting device 300 via the projector 200.

[0050] Next, in step S17, processing is performed based on the control signal. Specifically, as follows: Figure 9 As shown, the control unit 320 of the lighting device 300 causes the light-emitting unit 350 to perform processing based on the received control signal. Additionally, as a processing step in this embodiment, for example, the light-emitting unit 350 of the lighting device 300 is turned on.

[0051] Next, in step S18, a completion notification is sent to smartphone 100. Specifically, as follows: Figure 9 As shown, the control unit 210 of the projector 200 causes the communication unit 220 to send a completion signal indicating that the processing has been completed to the communication unit 130 of the smartphone 100. The display unit 150 of the smartphone 100 displays a message indicating that the light-emitting unit 350 of the lighting device 300 has been turned on.

[0052] In this way, even if the smartphone 100 is not compatible with the control protocol standard of the lighting device 300, the lighting device 300 can still be operated from the smartphone 100 via the projector 200. The lighting device 300 is thus controlled.

[0053] As described above, the lighting control method of this embodiment includes: pairing a smartphone 100 with a projector 200; reading a QR code 310 provided by the lighting device 300; sending the QR code 310 to the projector 200; pairing the projector 200 with the lighting device 300 based on the QR code 310; and sending a pairing completion signal to the smartphone 100.

[0054] According to this method, the projector 200 and the lighting device 300 are paired based on a QR code 310. Therefore, even if the smartphone 100 does not correspond to the control protocol standard (e.g., Matter) of the lighting device 300, a correspondence can still be established between the lighting device 300 and the smartphone 100 via the projector 200. That is, the user can control the lighting device 300 by operating the smartphone 100.

[0055] Furthermore, the lighting control method of this embodiment preferably includes the following steps: the smartphone 100 sends a control signal for controlling the lighting device 300 to the projector 200; the projector 200 sends a control signal to the lighting device 300; and the lighting device 300 executes the prescribed control based on the control instruction of the control signal. According to this method, the projector 200 and the lighting device 300 are paired based on a QR code 310. Therefore, even if the smartphone 100 does not correspond to the control protocol standard of the lighting device 300, a correspondence can be established between the lighting device 300 and the smartphone 100 via the projector 200. That is, the user can control the lighting device 300 by operating the smartphone 100.

[0056] The following describes variations of the above-described embodiments.

[0057] As described above, the control is not limited to the illumination device 300 located on the left side relative to the projection surface 400; the illumination device on the right side can also be controlled. When controlling the illumination device on the right side, the QR code of the illumination device on the right side is scanned in the same manner.

[0058] As mentioned above, it is not limited to using Matter as the control protocol; any general standard can be used, and other control protocols can also be used.

[0059] The following is a summary published in this note.

[0060] (Appendix 1) A lighting control method includes the following steps: pairing an information processing device with a display device; reading an identification code equipped with a lamp by the information processing device; sending the identification code to the display device by the information processing device; pairing the lamp with the display device based on the identification code; and sending a pairing completion signal to the information processing device by the display device.

[0061] According to this method, the display device and the luminaire are paired based on an identification code. Therefore, even if the information processing device does not correspond to the control protocol standard (e.g., Matter) of the luminaire, a correspondence can be established between the luminaire and the information processing device via the display device. That is, the luminaire can be controlled according to the operation of the information processing device.

[0062] (Appendix 2) The lighting control method according to Appendix 1 includes the following steps: the information processing device sends a control signal for controlling the luminaire to the display device; the display device sends the control signal to the luminaire; and the luminaire executes a predetermined control based on the control instruction of the control signal. According to this method, since the display device and the luminaire are paired based on an identification code, even if the information processing device does not correspond to the control protocol standard of the luminaire, a correspondence can be established between the luminaire and the information processing device via the display device. That is, the luminaire can be controlled according to the operation of the information processing device.
