The control unit 5 controls the luminaire 4. The control unit 5 includes, for example, a controller 5a and a power supply device 5b. The controller 5a controls the power supply device 5b. The control of the luminaire 4 is performed by the controller 5a controlling the power supply device 5b. FIG. 1 shows an example in which the controller 5a and the power supply device 5b exist as independent devices and are connected by a signal line 5c. The controller 5a may be a device integrated with the power supply device 5b. In such a case, for example, the controller 5a and the power supply device 5b are formed on one substrate. The control unit 5 corresponds to the first control unit within the scope of claims.

The control unit 5 radiates light from the luminaire 4. The control unit 5 emits red light from, for example, the red LED 11. The control unit 5 emits green light from the green LED 12. The control unit 5 emits blue light from the blue LED 13. The control unit 5 can individually control the red LED 11, the green LED 12, and the blue LED 13.

The control unit 5 regulates the light emitted from the luminaire 4. "Adjusting light" includes, for example, changing the intensity of light. "Adjusting the light" involves changing the color of the light. Any method may be adopted for adjusting the light. For example, amplitude control may be adopted to adjust the light emitted from the luminaire 4. In amplitude control, the brightness is adjusted by controlling the direct current of the LED. Further, PWM (Pulse Width Modulation) control may be adopted to adjust the light emitted from the luminaire 4. In PWM control, the LED is turned on and off at a constant frequency, and the brightness is adjusted by controlling the ratio of the on-time. The control unit 5 adjusts the light emitted from the red LED 11, for example. The control unit 5 adjusts the light emitted from the green LED 12. The control unit 5 adjusts the light emitted from the blue LED 13. The control unit 5 can individually adjust the light emitted from the red LED 11, the light emitted from the green LED 12, and the light emitted from the blue LED 13.

The control unit 5 causes the luminaire 4 to transmit specific information. For example, the control unit 5 causes the luminaire 4 to transmit identification information by changing the intensity of the light while maintaining the control conditions for illuminating the light radiated from the luminaire 4. The "control condition as illumination" is, for example, at least one of dimming degree, light color, and color temperature. For example, the control unit 5 transmits identification information from the luminaire 4 by slightly changing the brightness of the light radiated from the luminaire 4 while maintaining the color temperature at a certain reference value (or reference range). Let me. The identification information is information for identifying the lighting fixture 4. Unique identification information is assigned to the luminaire 4 in advance. The control unit 5 transmits identification information from the luminaire 4 by changing, for example, the light radiated from the red LED 11, the light radiated from the green LED 12, and the light radiated from the blue LED 13. Any method may be used to change the light in order to transmit the identification information from the luminaire 4. Various visible light communication technologies can be applied to the transmission of the identification information.

The control terminal 6 receives information from the outside. The control terminal 6 receives information via, for example, the network 15. The network 15 is, for example, an internet line. When the control terminal 6 receives information from the outside, the control terminal 6 transmits the received information to the communication device 7. The control terminal 6 and the communication device 7 are connected by a communication line 16a for lighting control. The control terminal 6 and the communication device 7 may be wirelessly connected. The control terminal 6 corresponds to a second control unit within the scope of claims.

The communication device 7 receives information from the control terminal 6. When the communication device 7 receives the information from the control terminal 6, the communication device 7 transmits the received information to the control unit 5. The communication device 7 and the control unit 5 are connected by, for example, a communication line 16b. That is, the information transmitted from the control terminal 6 is received by the control unit 5 via the communication device 7.

When the control terminal 6 receives information from the outside, the control terminal 6 transmits the received information to the corresponding control unit 5 via the communication device 7.

FIG. 3 is a diagram showing an example of the mobile terminal 2. The mobile terminal 2 may be an information communication terminal such as a smartphone. The mobile terminal 2 includes, for example, a receiving unit 17, a light receiving unit 18, a specific unit 19, an input unit 20, and a transmitting unit 21.

The receiving unit 17 receives information from the outside. The receiving unit 17 receives information via, for example, the network 15.

The light receiving unit 18 receives light from the outside. The light receiving unit 18 is, for example, a camera provided with an image sensor. As the image sensor, for example, CMOS (Complementary Metal Oxide Semiconductor) or CCD (Charge-Coupled Device) is adopted. Other techniques may be adopted as the image sensor. The light receiving unit 18 receives, for example, the light reflected by the bag 8 or the like among the light radiated from the luminaire 4.

The identification unit 19 identifies the identification information. The light radiated from the luminaire 4 is taken into the mobile terminal 2 by the light receiving unit 18. The identification unit 19 identifies the identification information based on, for example, the light received by the light receiving unit 18.

The input unit 20 is used to input information from the outside. Any method may be used for inputting information from the input unit 20. The input unit 20 may include, for example, a button. The input unit 20 may include a touch panel type sensor. From the input unit 20, for example, lighting information for the lighting fixture 4 is input. The lighting information is information for adjusting the light emitted from the lighting fixture 4. The lighting information is, for example, dimming information for changing the intensity of light emitted from the lighting fixture 4. The lighting information may be toning information for changing the color of the light emitted from the lighting fixture 4. The lighting information may include both dimming information and toning information.

The transmission unit 21 transmits information to the outside. The transmission unit 21 transmits information via, for example, the network 15. For example, the transmission unit 21 transmits the device identification information including the identification information specified by the specific unit 19 to the authentication server 3. Further, the transmission unit 21 transmits the lighting information input from the input unit 20 to the authentication server 3.

When the authentication server 3 receives the device identification information and the lighting information from, for example, the mobile terminal 2, the authentication server 3 transmits the received device identification information and the lighting information to the lighting control system 1. In the lighting control system 1, the control terminal 6 receives the fixture identification information and the lighting information.

Next, a series of operations performed in the dimming system will be described with reference to FIG. FIG. 4 is a flowchart showing an operation example of the dimming system according to the first embodiment of the present invention.

In the lighting control system 1, the control unit 5 controls the lighting fixture 4 and emits light from the lighting fixture 4. Further, the control unit 5 transmits identification information from the luminaire 4 by changing the intensity of the light radiated from the luminaire 4, for example (S101). At this time, the control unit 5 changes the intensity of the light while maintaining the control conditions for illuminating the light emitted from the luminaire 4. The identification information transmitted from the luminaire 4 in S101 is unique information assigned to the luminaire 4. The light radiated from the luminaire 4 hits the bag 8, the base 9, the wall 10, and the like, and is reflected.

Here, consider a case where a user wants to change the degree of light hitting the bag 8 which is a product or an exhibit. This user receives the reflected light from the bag 8 at the light receiving unit 18 of the mobile terminal 2 (S102). That is, the user takes a picture of the bag 8 with the camera of his / her smartphone.

The image sensor provided in the mobile terminal 2 such as a smartphone often has a frame rate of 30 fps when shooting a moving image. When such a mobile terminal 2 is used, the mobile terminal 2 naturally shoots the bag 8 at 30 fps. If the control unit 5 adjusts the intensity of light at a cycle synchronized with the frame rate of the mobile terminal 2 when transmitting the identification information, the identification information can be efficiently transmitted. In the above example, the identification information can be transmitted to the mobile terminal 2 at a communication speed of 30 bps. Further, when the bag 8 is photographed by a mobile terminal 2 or a digital device such as a digital camera, it is possible to suppress the occurrence of a striped pattern in the photographed image. The control unit 5 may adjust the intensity of light at a cycle synchronized with a frame rate of 24 fps, 60 fps, or 120 fps.

The identification unit 19 analyzes the reflected light from the bag 8 received by the light receiving unit 18 and identifies the identification information transmitted from the luminaire 4 (S103). The method for the specific unit 19 to specify the identification information may be any method. For example, the specific unit 19 may specify the identification information based on the light of a specific wavelength among the light received by the light receiving unit 18. The specific wavelength corresponds to, for example, the wavelength of red light (660 nm). The specific wavelength may correspond to the wavelength of green light (555 nm). The specific wavelength may correspond to the wavelength of blue light (460 nm).

For example, when the light receiving unit 18 receives light, the information detected by the light receiving unit 18 is input to the specific unit 19. The specific unit 19 extracts intensity information of a specific wavelength from the wavelengths of the light received by the light receiving unit 18 from the input information. The specific unit 19 extracts, for example, intensity information of the wavelength of red light (660 nm). The identification unit 19 identifies the identification information transmitted from the luminaire 4 based on the extracted intensity information.

When the identification information is specified by the specific unit 19, a screen for inputting lighting information is displayed on the display of the mobile terminal 2. The user inputs lighting information for the lighting fixture 4 from the input unit 20 according to the guidance displayed on the screen (S104). The lighting information is information for controlling the lighting fixture 4. The transmission unit 21 transmits the fixture identification information including the identification information specified in S103 and the lighting information input in S104 to the authentication server 3 (S105). The mobile terminal 2 may send and receive information a plurality of times with the authentication server 3 before transmitting the lighting information, for example, in order to acquire the information necessary for inputting the lighting information. Further, in order to transmit the device identification information and the lighting information from the mobile terminal 2 to the authentication server 3, another device not shown in FIG. 1 may be interposed.

The device identification information and the lighting information transmitted from the mobile terminal 2 are received by the authentication server 3. The authentication server 3 transmits the device identification information and the lighting information received from the mobile terminal 2 to the lighting control system 1 (S106).

In the lighting control system 1, the control terminal 6 determines at regular intervals whether or not the fixture identification information and the lighting information have been received. The device identification information and the lighting information transmitted from the authentication server 3 are received by the control terminal 6. When the control terminal 6 receives the fixture identification information and the lighting information corresponding to the fixture identification information (identification information), the control terminal 6 transmits the lighting information to the corresponding control unit 5 (S107). That is, when the control terminal 6 receives the identification information representing a certain lighting fixture 4, the control terminal 6 transmits the received lighting information together with the identification information to the control unit 5 that controls the lighting fixture 4. When the control unit 5 receives the lighting information from the control terminal 6, the control unit 5 adjusts the control conditions of the lighting fixture 4 based on the received lighting information. That is, when the control unit 5 receives the lighting information from the control terminal 6, the control unit 5 adjusts the light emitted from the lighting fixture 4 based on the received lighting information (S108).

In this lighting control system 1, identification information is transmitted from the lighting fixture 4. Further, when the control terminal 6 receives the identification information representing the lighting fixture 4, the light emitted from the lighting fixture 4 is adjusted based on the lighting information received by the control terminal 6 together with the identification information. The user can acquire the identification information of the lighting fixture 4 with his / her smartphone, for example, and transmit the lighting information for the lighting fixture 4. Therefore, the user can easily adjust the light near the luminaire 4, that is, within the reach of the reflected light.

In this lighting control system 1, the lighting fixture 4 can be specified by the identification information. Therefore, even when a plurality of luminaires 4 are provided, the light can be easily adjusted for each luminaire 4. The lighting control system 1 does not need to be provided with a large number of buttons or a large number of switches for specifying the lighting fixture 4, as in the conventional case.

If the dimming system is to be constructed by utilizing the existing system as much as possible, it is desirable that the authentication server 3 and the control terminal 6 are connected by an internet line. However, the authentication server 3 and the control terminal 6 may be connected by wire. Further, the function of the authentication server 3 and the function of the control terminal 6 may be included in one device.

FIG. 5 is a diagram showing another example of the dimming system according to the first embodiment of the present invention. FIG. 5 shows an example in which the luminaire 4 emits light toward a specific space. For example, the luminaire 4 radiates light toward a private room of a restaurant. In such a case, the user may directly receive the light from the luminaire 4 at the light receiving unit 18 of the mobile terminal 2. For example, the user captures the direct light from the lighting fixture 4 into the mobile terminal 2 by photographing the lighting fixture 4 with the camera of his / her smartphone. The user may take a picture of the wall 10 or the like exposed to the light from the lighting fixture 4 with the camera of his / her smartphone.

Considering the light receiving element provided in the camera of the smartphone, it is desirable that the luminaire 4 includes three-color (RGB) LEDs, that is, a red LED 11, a green LED 12, and a blue LED 13. If the luminaire 4 is equipped with three-color LEDs, the communication speed can be improved. However, if the luminaire 4 includes at least one of the red LED 11, the green LED 12, and the blue LED 13, the dimming system can be constructed. For example, the luminaire 4 may include only the red LED 11 and may not include the green LED 12 and the blue LED 13. The luminaire 4 includes a green LED 12 and a blue LED 13, and may not include a red LED 11. In such a case, the control unit 5 causes the luminaire 4 to transmit the identification information by changing the intensity of the light radiated from the LED provided in the luminaire 4.

FIG. 6 is a diagram showing another example of the luminaire 4 and the control unit 5. FIG. 6 shows an example in which the luminaire 4 includes a plurality of white LEDs 22 in addition to the plurality of red LEDs 11, the plurality of green LEDs 12, and the plurality of blue LEDs 13. The white LED 22 emits white light. FIG. 6 shows an example in which a plurality of white LEDs 22 are connected in series. The white LEDs 22 may be connected in parallel. The luminaire 4 may include only one white LED 22. The white LED 22 is controlled by the control unit 5.

When the luminaire 4 is provided with only three-color (RGB) LEDs, the color reproducibility is lowered as compared with the case where the luminaire 4 is provided with the white LED 22. When the luminaire 4 includes the white LED 22, the color reproducibility can be improved. The luminaire 4 may include an LED of one color of RGB and a white LED 22. The luminaire 4 may include two-color LEDs of RGB and a white LED 22.

When the luminaire 4 includes the white LED 22, the control unit 5 causes the luminaire 4 to transmit identification information by, for example, changing the intensity of light radiated from an LED other than the white LED 22. For example, the control unit 5 is emitted from the light emitted from the red LED 11, the light emitted from the green LED 12, and the blue LED 13 while maintaining the control conditions for illuminating the entire light emitted from the luminaire 4. Change the intensity of light. As a result, the identification information is transmitted from the luminaire 4. Further, when the control terminal 6 receives identification information representing a certain lighting fixture 4, for example, the control unit 5 has a white LED 22 provided on the lighting fixture 4 based on the lighting information received by the control terminal 6 together with the identification information. Adjusts the dimming intensity of the light emitted from. At this time, the control unit 5 has both the light radiated from the white LED 22 provided in the luminaire 4 and the light radiated from the LEDs other than the white LED 22 based on the lighting information received by the control terminal 6. The dimming degree may be adjusted. For example, the control unit 5 has a light emitted from the red LED 11, a light emitted from the green LED 12, a light emitted from the blue LED 13, and a light emitted from the white LED 22 based on the illumination information received by the control terminal 6. Adjust the dimming degree of.

FIG. 7 is a diagram showing another example of the luminaire 4 and the control unit 5. FIG. 7 shows an example in which the luminaire 4 includes a plurality of white LEDs 22. The luminaire 4 does not include the red LED 11, the green LED 12, and the blue LED 13. FIG. 7 shows an example in which a plurality of white LEDs 22 are connected in series. The white LEDs 22 may be connected in parallel. The luminaire 4 may include only one white LED 22.

When the luminaire 4 includes only the white LED 22, the control unit 5 transmits identification information from the luminaire 4 by changing the intensity of the light while maintaining the control conditions for illuminating the light emitted from the white LED 22. Let me. Further, when the control terminal 6 receives identification information representing a certain lighting fixture 4, for example, the control unit 5 has a white LED 22 provided on the lighting fixture 4 based on the lighting information received by the control terminal 6 together with the identification information. Adjusts the dimming intensity of the light emitted from. The light emitted from the white LED 22 includes light having a wavelength of 660 nm, light having a wavelength of 555 nm, and light having a wavelength of 460 nm. Therefore, in the mobile terminal 2, the identification information can be specified based on the extracted intensity information of the specific wavelength.

In the present embodiment, an example in which the lighting fixture 4 includes an LED has been specifically described. The luminaire 4 may include a light source other than the LED. For example, the luminaire 4 may include a light source such as an organic EL (Electroluminescence).

The luminaire 23 may include a light source other than the LED.

The control unit 5 controls the luminaire 4. For example, the control unit 5 radiates light from the luminaire 4. The control unit 5 regulates the light emitted from the luminaire 4. Further, the control unit 5 causes the luminaire 4 to transmit specific information. For example, the control unit 5 causes the luminaire 4 to transmit identification information by changing the intensity of the light while maintaining the control conditions for illuminating the light radiated from the luminaire 4. When the luminaire 4 includes three-color (RGB) LEDs, the control unit 5 changes the intensity of the light emitted from the red LED 11, the light emitted from the green LED 12, and the light emitted from the blue LED 13. , The lighting fixture 4 transmits the identification information.

The control unit 5 controls the luminaire 23. For example, the control unit 5 radiates light from the luminaire 23. The control unit 5 emits white light from, for example, the white LED 22. Further, the control unit 5 adjusts the light emitted from the luminaire 23. In the present embodiment, the luminaire 23 is for lighting and is not used for visible light communication. That is, the identification information is not transmitted from the luminaire 23.

In the lighting control system 1 of the present embodiment, when the control terminal 6 receives the fixture identification information and the lighting information corresponding to the fixture identification information (identification information), the control terminal 6 transmits the lighting information to the corresponding control unit 5. That is, when the control terminal 6 receives the identification information representing a certain lighting fixture 4, the control terminal 6 transmits the received lighting information together with the identification information to the control unit 5 that controls the lighting fixture 4. When the control unit 5 receives the lighting information from the control terminal 6, the control unit 5 adjusts the control conditions of the lighting fixture 4 based on the received lighting information.

Further, when the control unit 5 receives the lighting information from the control terminal 6, the control unit 5 adjusts the control conditions of the lighting fixture 23 based on the received lighting information. That is, when the control unit 5 receives the lighting information from the control terminal 6, the control unit 5 adjusts the dimming intensity of the light radiated from the lighting fixture 23 based on the received lighting information. That is, when the control unit 5 receives the lighting information from the control terminal 6, it controls both the lighting fixture 4 and the lighting fixture 23 to adjust the light that hits the bag 8.

In the lighting control system 1, when the control terminal 6 receives the identification information representing the lighting fixture 4, both the light emitted from the lighting fixture 4 and the light emitted from the lighting fixture 23 are adjusted. Since the lighting fixture 23 used exclusively for lighting is provided, the color reproducibility can be improved.

As described in the first embodiment, the luminaire 4 does not necessarily have to be provided with three-color LEDs. The present dimming system can be constructed if the luminaire 4 includes at least one of the red LED 11, the green LED 12, and the blue LED 13. In such a case, the control unit 5 causes the luminaire 4 to transmit the identification information by changing the intensity of the light radiated from the LED provided in the luminaire 4.

In the present embodiment, the identification information is information for identifying the luminaire 23. Unique identification information is assigned to the luminaire 23 in advance. The light emitter 24 transmits identification information representing the lighting fixture 23, for example, by changing the intensity of the light emitted from the red LED 11, the light emitted from the green LED 12, and the light emitted from the blue LED 13. Any method may be used to change the light in order to transmit the identification information from the light emitter 24.

The control unit 5 controls the luminaire 23. For example, the control unit 5 radiates light from the luminaire 23. The control unit 5 emits white light from, for example, the white LED 22. Further, the control unit 5 adjusts the control conditions of the luminaire 23. For example, the control unit 5 adjusts the dimming intensity of the light emitted from the luminaire 23. The luminaire 23 is for lighting and is not used for visible light communication.

In the lighting control system 1 of the present embodiment, when the control terminal 6 receives the fixture identification information and the lighting information corresponding to the fixture identification information (identification information), the control terminal 6 transmits the lighting information to the corresponding control unit 5. That is, when the control terminal 6 receives the identification information representing the lighting fixture 23 transmitted by the light emitter 24, the control terminal 6 transmits the received lighting information together with the identification information to the control unit 5 that controls the lighting fixture 23. When the control unit 5 receives the lighting information from the control terminal 6, the control unit 5 adjusts the control conditions of the lighting fixture 23 based on the received lighting information.

Embodiment 4.
FIG. 10 is a diagram showing an example of a dimming system according to the fourth embodiment of the present invention. The dimming system includes, for example, a lighting control system 1, a mobile terminal 2, and an authentication server 3. The lighting control system 1 includes, for example, a lighting fixture 4, a control unit 5, a control terminal 6, and a communication device 7. The dimming system shown in the present embodiment includes all the functions disclosed in the first embodiment. Further, the dimming system shown in the present embodiment has a function of transmitting information for identifying a position to a meeting partner. The unique functions of this system will be described in detail below.

The luminaire 4 emits light. The luminaire 4 emits light, for example, to illuminate a particular object to be illuminated. The luminaire 4 may radiate light toward a specific space. FIG. 10 shows an example in which a luminaire 4 is used to illuminate a creation 25 created by an artist. The light emitted from the luminaire 4 hits the creation 25. A part of the light that hits the creation 25 is reflected by the creation 25. Further, the light radiated from the lighting fixture 4 also hits the table 26 on which the creation 25 is placed, the wall 10 facing the creation 25 side, and the like. A part of the light that hits the table 26 is reflected by the table 26. A part of the light that hits the wall 10 is reflected by the wall 10. In FIG. 10, among such reflected light, the light directed toward the mobile terminal 2 is indicated by an arrow A. As shown in FIG. 2, for example, the luminaire 4 includes a plurality of red LEDs 11, a plurality of green LEDs 12, and a plurality of blue LEDs 13.

The control unit 5 controls the luminaire 4. For example, the control unit 5 radiates light from the luminaire 4. The control unit 5 regulates the light emitted from the luminaire 4. Further, the control unit 5 causes the luminaire 4 to transmit specific information. For example, the control unit 5 causes the luminaire 4 to transmit identification information by changing the intensity of the light while maintaining the control conditions for illuminating the light radiated from the luminaire 4. When the luminaire 4 includes three-color LEDs, the control unit 5 changes at least one of the light emitted from the red LED 11, the light emitted from the green LED 12, and the light emitted from the blue LED 13. This causes the lighting fixture 4 to transmit the identification information.

FIG. 11 is a diagram showing an example of the mobile terminal 2. The mobile terminal 2 includes, for example, a receiving unit 17, a light receiving unit 18, a specific unit 19, an input unit 20, and a transmitting unit 21, as well as a display unit 27. The receiving unit 17, the light receiving unit 18, the specific unit 19, the input unit 20, and the transmitting unit 21 all have the functions disclosed in the first embodiment. Further, in the example shown in this embodiment, the light receiving unit 18 is used to acquire an image. When an image is acquired by the light receiving unit 18, a part of the light radiated from the lighting fixture 4 is taken into the mobile terminal 2 by the light receiving unit 18. The display unit 27 displays information.

Next, a series of operations performed in this dimming system will be described with reference to FIG. FIG. 12 is a flowchart showing an operation example of the dimming system according to the fourth embodiment of the present invention. In the following, an example in which the owner of the mobile terminal 2 and the owner of the mobile terminal 28 are meeting will be described. The mobile terminal 28 is an information communication terminal such as a smartphone.

In the lighting control system 1, the control unit 5 controls the lighting fixture 4 and emits light from the lighting fixture 4. Further, the control unit 5 causes the lighting fixture 4 to transmit identification information by changing the intensity of the light radiated from the lighting fixture 4, for example (S201). The identification information transmitted from the luminaire 4 in S201 is unique information assigned to the luminaire 4. That is, the identification information represents the luminaire 4. The light radiated from the luminaire 4 hits the creation 25, the pedestal 26, the wall 10, and the like, and is reflected.

For example, consider a case where the meeting place between the owner of the mobile terminal 2 and the owner of the mobile terminal 28 is in front of the creation 25. Further, it is assumed that the owner of the mobile terminal 2 arrives at the meeting place first. When the owner of the mobile terminal 2 arrives at the meeting place, the camera provided in the mobile terminal 2 takes a picture of the creation 25 which is a mark of the meeting place (S202). As a result, the light receiving unit 18 acquires an image of the creation 25. Further, the light receiving unit 18 receives the light radiated from the luminaire 4.

The identification unit 19 analyzes the light received by the light receiving unit 18 and identifies the identification information transmitted from the luminaire 4 (S203). The method for the specific unit 19 to specify the identification information may be any method. For example, the specific unit 19 may specify the identification information based on the light of a specific wavelength among the light received by the light receiving unit 18. The specific wavelength corresponds to, for example, the wavelength of red light. The specific wavelength may correspond to the wavelength of green light. The specific wavelength may correspond to the wavelength of blue light.

For example, when the light receiving unit 18 receives light, the information detected by the light receiving unit 18 is input to the specific unit 19. The specific unit 19 extracts intensity information of a specific wavelength from the wavelengths of the light received by the light receiving unit 18 from the input information. The specific unit 19 extracts, for example, intensity information of the wavelength of red light. The identification unit 19 identifies the identification information transmitted from the luminaire 4 based on the extracted intensity information.

When the identification information is specified by the identification unit 19, the transmission unit 21 transmits the device identification information including the identification information specified in S203 to the authentication server 3 (S204). In S204, the transmission unit 21 may transmit the device identification information to the authentication server 3 via another device (not shown in FIG. 10).

The device identification information transmitted from the mobile terminal 2 is received by the authentication server 3. When the mobile terminal 2 transmits the fixture identification information in S204, the mobile terminal 2 receives the fixture position information indicating the position of the lighting fixture 4 as a response. The fixture position information includes, for example, a map and information indicating where the lighting fixture 4 is located on the map. When the luminaire 4 is present in the building, the luminaire position information may include a floor map of the building and information indicating where the luminaire 4 is located on the floor map. Other information may be included in the device position information.

For example, the authentication server 3 stores the identification information of the lighting fixture 4 and the fixture position information of the lighting fixture 4 in association with each other. In such a case, when the authentication server 3 receives the fixture identification information of the lighting fixture 4 from the mobile terminal 2, the authentication server 3 can specify the fixture position information of the lighting fixture 4 based on the received fixture identification information (Yes in S205). .. When the authentication server 3 specifies the fixture position information of the lighting fixture 4 based on the received fixture identification information, the authentication server 3 transmits the identified fixture position information to the mobile terminal 2 (S209). In the mobile terminal 2, the receiving unit 17 receives the fixture position information of the lighting fixture 4 from the authentication server 3 as a response to the fixture identification information of the lighting fixture 4 transmitted by the transmitting unit 21.

The authentication server 3 may store the identification information of the luminaire 4 and the detailed information of the irradiated object exposed to the light from the luminaire 4 in association with each other. In the example shown in this embodiment, the irradiated object is the creation 25. In such a case, for example, information such as the name of the creator, the career of the creator, and the content expressed by the creation 25 is stored in the authentication server 3 as detailed information of the irradiated object. For example, when the authentication server 3 receives the fixture identification information of the lighting fixture 4 from the mobile terminal 2, the authentication server 3 identifies the detailed information of the creation 25 based on the received fixture identification information. When the authentication server 3 specifies the detailed information of the creation 25 based on the received device identification information, the authentication server 3 transmits the specified detailed information together with the device position information to the mobile terminal 2 (S209). In the mobile terminal 2, as a response to the fixture identification information of the lighting fixture 4 transmitted by the transmitting unit 21, the receiving unit 17 receives the fixture position information of the lighting fixture 4 and the detailed information of the creation 25 from the authentication server 3.

The above is an example in which the device position information and the detailed information of the irradiated object are stored in the authentication server 3. The authentication server 3 can communicate with the lighting control system 1 provided with the lighting fixture 4. The identification information of the lighting fixture 4 and the fixture position information of the lighting fixture 4 may be associated and stored in the lighting control system 1. In such a case, even if the authentication server 3 receives the fixture identification information of the lighting fixture 4 from the mobile terminal 2, the authentication server 3 cannot specify the fixture position information of the lighting fixture 4 based on the received fixture identification information (S205). No). When the authentication server 3 receives the fixture identification information of the lighting fixture 4 from the mobile terminal 2, the authentication server 3 transmits the received fixture identification information to the lighting control system 1 in order to acquire the fixture position information of the lighting fixture 4 (S206).

The fixture identification information of the lighting fixture 4 transmitted from the authentication server 3 is received by the control terminal 6 in the lighting control system 1. When the control terminal 6 receives the fixture identification information of the lighting fixture 4 from the authentication server 3, the control terminal 6 identifies the fixture position information of the lighting fixture 4 based on the received fixture identification information (S207). When the control terminal 6 specifies the fixture position information of the lighting fixture 4 based on the received fixture identification information, the control terminal 6 transmits the identified fixture position information to the authentication server 3 (S208). When the authentication server 3 receives the fixture position information of the lighting fixture 4 from the lighting control system 1, it transmits the received fixture position information to the mobile terminal 2 (S209). In the mobile terminal 2, the receiving unit 17 receives the fixture position information of the lighting fixture 4 from the authentication server 3 as a response to the fixture identification information of the lighting fixture 4 transmitted by the transmitting unit 21.

Similarly, the lighting control system 1 may store the identification information of the lighting fixture 4 and the detailed information of the irradiated object to which the light from the lighting fixture 4 hits in association with each other. In such a case, when the authentication server 3 receives the fixture identification information of the lighting fixture 4 from the mobile terminal 2, the authentication server 3 transmits the received fixture identification information to the lighting control system 1 in order to acquire detailed information of the irradiated object.

The fixture identification information of the lighting fixture 4 transmitted from the authentication server 3 is received by the control terminal 6 in the lighting control system 1. When the control terminal 6 receives the fixture identification information of the lighting fixture 4 from the authentication server 3, the control terminal 6 identifies the detailed information of the irradiated object based on the received fixture identification information. In the example shown in this embodiment, the control terminal 6 specifies the detailed information of the creation 25. When the control terminal 6 specifies the detailed information of the creation 25 based on the received device identification information, the control terminal 6 transmits the specified detailed information to the authentication server 3. When the authentication server 3 receives the detailed information of the creation 25 from the lighting control system 1, the authentication server 3 transmits the received detailed information to the mobile terminal 2. In the mobile terminal 2, as a response to the fixture identification information of the lighting fixture 4 transmitted by the transmitting unit 21, the receiving unit 17 receives the fixture position information of the lighting fixture 4 and the detailed information of the creation 25 from the authentication server 3.

The authentication server 3 may acquire only the fixture position information from the lighting control system 1. The authentication server 3 may acquire only the detailed information of the irradiated object from the lighting control system 1. The authentication server 3 may acquire both the fixture position information and the detailed information of the irradiated object from the lighting control system 1.

When the receiving unit 17 receives the fixture position information of the lighting fixture 4 from the authentication server 3, the transmitting unit 21 transfers the fixture position information received from the authentication server 3 and the image of the creation 25 acquired by the light receiving unit 18 in S202. It is transmitted to the mobile terminal 28 (S210). Information may be transmitted from the mobile terminal 2 to the mobile terminal 28 by using the mail function or the message function. The above information may be transmitted using another communication function.

The mobile terminal 28 includes, for example, a display unit. When the mobile terminal 28 receives the fixture position information of the lighting fixture 4 and the image of the creation 25 from the mobile terminal 2, the display unit displays the information (S211). FIG. 13 is a diagram showing a display example of the mobile terminal 28. FIG. 13A shows an example of the device position information displayed on the mobile terminal 28. FIG. 13A shows an example in which a floor map of a building and information indicating where the lighting fixture 4 is located on the floor map are displayed on the mobile terminal 28. In the example shown in FIG. 13A, the position of the luminaire 4 is indicated by a star. The owner of the mobile terminal 28 can confirm the meeting place on the floor map by looking at the displayed device position information.

FIG. 13B shows an example of an image of the creation 25 displayed on the mobile terminal 28. The owner of the mobile terminal 28 can display the image of the creation 25 by scrolling the screen from the state shown in FIG. 13A, for example. By looking at the displayed image of the creation 25, the owner of the mobile terminal 28 can confirm the actual image of the meeting place, which cannot be known only from the device position information.

When the transmission unit 21 transmits the device position information and the image of the creation 25 to the mobile terminal 28, the display unit 27 displays the detailed information of the creation 25 received from the authentication server 3 by the reception unit 17 and the light receiving unit 18 in S202. The acquired image of the creation 25 is displayed (S212). FIG. 14 is a diagram showing a display example of the mobile terminal 2. FIG. 14A shows an example of an image of the creation 25 displayed on the mobile terminal 2. FIG. 14B shows an example of detailed information on the creation 25 displayed on the mobile terminal 2. The owner of the mobile terminal 2 can display the detailed information of the creation 25 by scrolling the screen from the state shown in FIG. 14A, for example.

The owner of the mobile terminal 2 arrives at the meeting place before the owner of the mobile terminal 28. The owner of the mobile terminal 2 can see the contents displayed on the display unit 27 and wait for the owner of the mobile terminal 28 to arrive. In a large commercial facility, the light from the lighting fixture 4 may be applied to the products in the store. In such a case, the image of the product and the detailed information of the product are displayed on the mobile terminal 2 in S212. The mobile terminal 2 can be used as an advertising medium and can contribute to product sales.
