[0011] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present disclosure will be described with reference to the drawings. The same or corresponding components are designated by the same reference numerals, and repeated description may be omitted.

[0012] First embodiment 1 is a diagram showing a wall-mounted lighting device 2 according to a first embodiment of the present disclosure, in which the upper direction on the page corresponds to the ceiling direction, and the lower direction on the page corresponds to the floor direction.

[0013] The wall-mounted lighting fixture 2 is attached to a wall 10 via a main body 11. The wall-mounted lighting fixture 2 includes a lighting circuit 12. The lighting circuit 12 is connected to a commercial power source and supplies current received from the commercial power source to a light source 14 via a substrate 13. The cover 16 is made of a light-transmitting material and has airtightness and light diffusibility.

[0014] The substrate 13 has a base material made of a metal such as aluminum, which has good heat dissipation properties. The substrate 13 is not limited to one using a metal base material. For example, the heat dissipation properties of the substrate 13 can be improved by using a double-sided substrate in which circuits are arranged on both sides of the substrate. A light source 14 is arranged on the surface of the substrate 13 opposite the wall. Furthermore, a first connector 20 for connecting a vital sign monitoring device 15 is arranged on the substrate 13.

[0015] The first connector 20 is disposed on the same surface as the light source 14. This ensures that the detection range of the biological information monitoring device 15 connected to the first connector 20 is not blocked by the light source 14.

[0016] The orientation of the vital information monitoring device 15 is adjusted by a hinge 34, which will be described later, so that the vital sensor 30 faces the area in which people are present when the device is connected to the first connector 20. In the case of a wall-mounted lighting fixture 2 that is installed at a high position in a room, it is desirable for the vital sensor 30 of the vital information monitoring device 15 to face the floor surface. Therefore, the vital sensor 30 is adjusted so that it faces diagonally downward on the page as shown in FIG. 1.

[0017] In addition, while FIG. 1 illustrates an example of a wall-mounted lighting fixture 2, the lighting fixture of the present disclosure is not limited to the wall-mounted type, and may be, for example, a straight tube lighting fixture 4, a ceiling lighting fixture 3, or another type.

[0018] 2 is a diagram showing a ceiling lighting fixture 3 according to the first embodiment of the present disclosure. The ceiling lighting fixture 3 is attached to a ceiling 60 via a main body 11. As with the wall-mounted lighting fixture 2, the vital information monitoring device 15 here is also adjusted so that the vital sensor 30 faces the floor surface, which is located downward in the plane of the drawing, when connected to the first connector 20.

[0019] When there is no need to distinguish between the wall-mounted lighting fixture 2, the ceiling lighting fixture 3, and the straight tube lighting fixture 4, they will hereinafter be referred to simply as lighting fixture 9.

[0020] 3 is an arrangement diagram of light sources 14 and first connectors 20 on substrate 13 according to embodiment 1 of the present disclosure. A plurality of light sources 14 are arranged concentrically on substrate 13. Light source 14 includes warm white LED 141 with a color temperature of 2700K and white LED 142 with a color temperature of 6500K. Warm white LED 141 and white LED 142 are arranged alternately on the concentric circles. Note that the color temperature here is merely an example and is not limited.

[0021] The first connectors 20 are disposed around the light sources 14. In this manner, it is desirable that the first connectors 20 are disposed outside the multiple light sources 14 so as not to block the light emitted from the multiple light sources 14.

[0022] Although the number of first connectors 20 is not limited, arranging a plurality of first connectors 20 as shown in Fig. 3 allows the user to select a suitable first connector 20 and then connect the vital sign monitoring device 15. That is, the user can select a suitable first connector 20 according to the installation position of the lighting device 9 and the presence range of the person to be detected, so that the detection range of the vital sensor 30 overlaps most closely with the presence range of the person to be detected. Note that the arrangement of a plurality of first connectors 20 is not limited to the example shown in Fig. 3, and may be determined according to the shape of the substrate 13, etc.

[0023] A second connector 22 disposed in the center of the substrate 13 electrically connects the lighting circuit 12 and the light source 14. A plurality of screws 21 are used to fasten the substrate 13 and the main body 11 together.

[0024] In order to prevent all light sources 14 from being turned off in the event of a malfunction, it is desirable to combine the multiple warm white LEDs 141 in a circuit such that some are connected in series and some are connected in parallel. The same is true for the white LEDs 142.

[0025] FIG. 4 is a configuration example of the biological information monitoring device 15 according to the first embodiment of the present disclosure. The vital sensor 30 is mounted on a substrate 39. The vital sensor 30 detects biological information such as the presence or absence of a person, the heart rate, and the respiratory rate by the Doppler effect. The control circuit 32 notifies the lighting circuit 12 of the biological information detected by the vital sensor 30. Furthermore, the control circuit 32 transmits the biological information collected from the vital sensor 30 to an external device via a wireless device 31. Examples of the communication method of the wireless device 31 include Wi-Fi (registered trademark) and Bluetooth Low Energy (registered trademark). Furthermore, wireless communication using a frequency band used in the sub-gigahertz band or the fifth generation mobile communication system (5G) may be used.

[0026] The secondary battery 33 functions as a power source for driving the biological information monitoring device 15 when the power to the lighting fixture 9 is turned off.

[0027] The third connector 35 is a connector for connecting the vital information monitoring device 15 to the first connector 20. A hinge 34 is provided between the third connector 35 and the substrate 39 as a movable part, and the angle of the substrate 39 can be changed. This allows the angle of the vital sensor 30 to be adjusted so that it faces the range in which a person is present. Note that the mechanism for adjusting the angle is not limited to the hinge 34. For example, a mechanism using a screw or a clamp, or other methods may be used.

[0028] 5 shows an example of the configuration of the third connector 35 of the biological information monitoring device 15 according to the first embodiment of the present disclosure. An end view is shown here. A support material 36 is disposed in the center of the third connector 35. A plurality of electrodes 37 are disposed around the support material 36 so as to be symmetrical vertically and horizontally. The plurality of electrodes 37 includes ten electrodes, 37(1) to 37(10). The pin assignment of the electrodes 37 is as follows: Electrode 37(1), Electrode 37(10): Vcc5V Electrode 37(2), Electrode 37(9):TX Electrode 37(3), Electrode 37(8):RX Electrode 37(4), Electrode 37(7):CLK Electrode 37(5), Electrode 37(6): GND

[0029] In this way, the third connector 35 has a mechanically and electrically symmetrical structure so that it can be connected to the first connector 20 regardless of the orientation. Naturally, the multiple electrodes provided in the first connector 20, which is the connection counterpart, also have a mechanically and electrically symmetrical structure.

[0030] Here, the vital sensor 30 is mounted on one side of the substrate 39. Therefore, if the first connector 20 and the third connector 35 do not have a symmetrical structure as described above, if a manufacturing error causes one of the connectors to be misoriented, the vital sensor 30 will face away from the floor surface. If the first connector 20 and the third connector 35 have a symmetrical structure as in the present disclosure, this will not occur.

[0031] 6 is a diagram showing the detection range of the biological information monitoring device 15 according to the first embodiment of the present disclosure. In the biological information monitoring device 15, the detection range of the vital sensor 30 is 60 degrees in the X direction and 45 degrees in the Y direction. In the Y direction, which is particularly narrow, the orientation of the vital sensor 30 can be adjusted by the hinge 34. Note that the numerical values ​​of the detection range are merely examples.

[0032] 7 is a block diagram of lighting device 9 according to embodiment 1 of the present disclosure. Lighting circuit 12 is connected to commercial power supply 40 via terminal block 41. Power supply circuit 42 converts AC voltage from commercial power supply 40 into DC voltages of 5 V and 45 V.

[0033] The 5V DC voltage is a voltage for driving the control circuit 43. The 5V DC voltage is also supplied to the first connector 20. On the other hand, the 45V DC voltage is a voltage for driving the lighting circuits 44 and 46. The lighting circuit 44 controls the lighting of the warm white LED 141 included in the light source 14. On the other hand, the lighting circuit 46 controls the lighting of the white LED 142 included in the light source 14. The third connector 35 of the biological information monitoring device 15 is connected to the first connector 20.

[0034] The control circuit 32 of the vital information monitoring device 15 notifies the lighting circuit 12 of the vital information detected by the vital sensor 30. For example, when the vital sensor 30 detects a person, the control circuit 32 notifies the control circuit 43 of the lighting circuit 12 of information indicating the presence of a person. The control circuit 43 that has received the information keeps the light source 14 on. On the other hand, when the vital sensor 30 detects the absence of a person, the control circuit 32 notifies the control circuit 43 of information indicating the absence of a person. The control circuit 43 that has received the information turns off the light source 14 after a preset time has elapsed. This makes it possible to prevent the lighting device 9 from being immediately turned off when a person is temporarily out of the detection range of the vital information monitoring device 15 but is still using the lighting device 9.

[0035] Furthermore, when at least one of the person's heart rate and respiratory rate detected by the vital sensor 30 is higher than a specified value, the control circuit 32 notifies the control circuit 43 of information indicating that the person is active. The control circuit 43 that receives the information turns on the white LED 142 at a predetermined brightness. By turning on the lighting device 9 with the highly visible white LED 142, it is possible to create an illumination state in which an active person feels comfortable. The predetermined brightness is preferably about 700 lx, but any value is acceptable as long as the brightness is felt to be sufficiently bright by an active person.

[0036] On the other hand, when at least one of the heart rate and respiratory rate of the person detected by vital sensor 30 is lower than the specified value, control circuit 32 notifies control circuit 43 of information indicating that the person is relaxing. Control circuit 43 that receives this information turns on warm white LED 141 so that its brightness fluctuates at 1 / f, where f is the light frequency of warm white LED 141. By fluctuating the brightness of warm white LED 141 at 1 / f, it is possible to create an illumination state in which the person detected by vital sensor 30 can feel more relaxed.

[0037] Thus, in lighting fixture 9 of the present disclosure, first connector 20 for connecting vital information monitoring device 15 is disposed on the same surface as light source 14 on substrate 13. Furthermore, the orientation of vital information monitoring device 15 is adjusted by the movable part so that vital sensor 30 faces the range in which a person is present while connected to first connector 20. This allows vital information monitoring device 15 to be attached so that the detection range of vital sensor 30 is not blocked by light source 14, and lighting fixture 9 can be provided in which vital sensor 30 can be adjusted to face the direction in which a person is present.

[0038] Furthermore, in the lighting device 9 of the present disclosure, the lighting state is controlled based on the biological information detected by the vital sensor 30. This makes it possible to create a lighting state that the detected person feels comfortable. In view of this effect, it is particularly preferable that the lighting device 9 of the present disclosure is installed in a bathroom where the heart rate and respiration rate of the person in the room are likely to change. For example, it is known that the heart rate and respiration rate increase when a person is washing the body. In this case, the lighting device 9 determines that the person is active and turns on the white LED 142. On the other hand, it is known that the heart rate and respiration rate decrease when a person is soaking in a bathtub. In this case, the lighting device 9 determines that the person is relaxing and turns on the warm white LED 141 so that the brightness fluctuates at 1 / f.

[0039] In the above-described lighting fixture 9, first connector 20 for connecting vital sign monitoring device 15 is arranged on the same surface of substrate 13 as light source 14. However, vital sign monitoring device 15 and light source 14 do not necessarily have to be arranged on the same substrate 13 as long as they are arranged on the same surface. This point is common to all of the following embodiments.

[0040] Embodiment 2 In this embodiment, a monitoring system using the lighting device 9 of the first embodiment will be described.

[0041] FIG. 8 illustrates an example of a system configuration of a monitoring system 100 according to the second embodiment of the present disclosure.

[0042] The monitoring system 100 includes one or more lighting fixtures 9 according to embodiment 1. Here, the monitoring system 100 includes a wall-mounted lighting fixture 2, a ceiling lighting fixture 3, and a straight tube lighting fixture 4. The monitoring system 100 further includes a server 1 and a cloud system 7.

[0043] The lighting fixtures 9 and the server 1 are arranged in a house or the like. For example, the wall-mounted lighting fixture 2 is installed on the wall of a bathroom, the ceiling lighting fixture 3 is installed on the ceiling of a living room, the straight tube lighting fixture 4 is installed above the kitchen, etc. However, the type and installation location of the lighting fixture 9 are not limited to this.

[0044] Each lighting fixture 9 transmits lighting information and biological information detected by vital sensor 30 to server 1 via wireless device 31. The lighting information of lighting fixture 9 includes, for example, on / off status, fault status, power consumption, LED current, and LED voltage.

[0045] The server 1 notifies the cloud system 7 of the lighting information and biometric information received from each lighting fixture 9 via the LAN 5. The cloud system 7 manages the lighting information and biometric information received from the server 1 for each lighting fixture 9. Furthermore, the cloud system 7 discloses the biometric information to the terminal 8 in response to a request from a user of the terminal 8. This allows the user of the terminal 8 to remotely check the biometric information of people in the house where the lighting fixture 9 is located.

[0046] In the first embodiment, it has been described that the lighting device 9 determines a suitable lighting state based on the biological information detected by the vital sensor 30, and controls the lighting of the light source 14 to achieve the suitable lighting state. However, the suitable lighting state may be determined by the server 1 or the cloud system 7. This eliminates the need to determine the lighting state for each lighting device 9, thereby reducing the burden.

[0047] 9 is a block diagram of a cloud system 7 according to the second embodiment of the present disclosure. The security management processing circuit 50 receives illumination information and biological information from the server 1. Furthermore, the security management processing circuit 50 receives a signal for operating the cloud system 7 from the terminal 8.

[0048] The security management processing circuit 50 refers to the authentication information previously stored in the first memory 52 and determines whether the server 1 that notified the cloud system 7 of information or the terminal 8 that sent an operation signal to the cloud system 7 is a party that should be approved. If the party is a party that should be approved, the security management processing circuit 50 approves the access of the server 1 or the terminal 8 to the cloud system 7. This allows the communication management processing circuit 51 to receive the illumination information and biometric information from the server 1, and the operation signal from the terminal 8.

[0049] The first memory 52 stores authentication information of the server 1 and the terminal 8 that should be permitted to access the cloud system 7 in the form of an ID, a password, etc. Note that the authentication information is collected, for example, by a notification registration service in which the user registers in advance.

[0050] The analysis processing circuit 55 analyzes the biometric information received by the communication management processing circuit 51 and determines an appropriate lighting state using a machine learning learning model 56. The second memory 54 stores the biometric information analyzed by the analysis processing circuit 55 and the determined lighting state. The control processing circuit 57 notifies the server 1 of the lighting state determined by the analysis processing circuit 55 via the communication management processing circuit 51 and the security management processing circuit 50. The server 1 that receives the lighting state information notifies the target lighting fixture 9 of the information. This allows the lighting fixture 9 to perform lighting control based on the lighting state.

[0051] Furthermore, the control processing circuit 57 performs a requested operation based on the operation signal received by the communication management processing circuit 51. When the operation content is disclosure of biometric information, the control processing circuit 57 discloses the biometric information to the terminal 8 via the communication management processing circuit 51 and the security management processing circuit 50. Note that the disclosure to the terminal 8 may be in the form of an app or the like as a visualization service.

[0052] The voice recognition processing circuit 53 receives an operation signal issued as voice information from the terminal 8 that has been approved as described above.

[0053] In this way, according to this embodiment, it is possible to provide a monitoring system 100 that uses a lighting fixture 9 that can be installed so that the detection range of the vital sensor 30 is not obstructed by the light source 14 and that can be adjusted so that the vital sensor 30 faces in the direction in which a person is present.

[0054] The processes performed by the lighting fixtures 9, the server 1, and the cloud system 7 may be executed by a program using a computer having a CPU and memory and storing a program in the memory. Alternatively, the processes may be executed by a program using an integrated circuit such as an FPGA (Field Programmable Gate Array). The programs may be provided by being recorded on a storage medium, or may be provided via a network. This point is common to all the embodiments.

[0055] The present disclosure is not limited to the above-described embodiment, and various modifications can be made in the implementation stage without departing from the spirit of the present disclosure. In addition, the embodiments may be implemented in appropriate combination, and in that case, the combined effects can be obtained.
