Description

Technical Field

[0001] The present invention relates to a lighting device, a living body movement detection system, a living body movement detection method, a program, and a recording medium.

Background Art

[0002] With the recent aging of society, the number of elderly people dying alone has been increasing, becoming a social problem. From such a situation, especially in the case of elderly people living alone, when renting a dwelling unit, there are also frequent cases where the landlord refuses to conclude a tenancy agreement from the landlord who is concerned about dying alone. On the other hand, even though there are many applicants for occupancy on the landlord's side, there is a problem that the dwelling unit cannot be rented even if the landlord wants to rent it, resulting in vacant rooms. For this reason, measures for preventing the solitary death of the elderly and for early detection of a crisis are desired. This problem is the same for, for example, not only the elderly but also, for example, disabled people living alone, sick people, etc.

[0003] Therefore, as a method for early detection of the solitary death of residents, etc., for example, a system has been reported in which an abnormality detector is installed in a dwelling unit and a notification is made to a monitoring center when an abnormality is detected (Patent Document 1).

[0004] However, installing a dedicated abnormality detector for each dwelling unit is costly and there is also a problem of installation space. Especially in the case of apartments for single-person households, since the landlord owns a large number of dwelling units, the hurdle for introduction is high.

Modes for Carrying Out the Invention

[0014] As described above, the present invention is useful for external parties to detect the safety of residents who may become unable to move within their dwelling, such as the elderly, disabled, and ill. The bio-movement detection system and bio-movement detection method of the present invention can be implemented, for example, by installing the lighting device of the present invention as a lighting device in the dwelling of the subject, and by having a third party (hereinafter referred to as a caregiver) who wants to know the status of the subject possess an external terminal. The caregiver is, for example, the homeowner of the dwelling, the subject's family, caregiver, nurse, etc. According to the present invention, for example, it is possible to detect whether the subject is inside the dwelling, whether they are moving inside the dwelling, whether the door is locked or unlocked, and whether the door is opened or closed. Therefore, if the caregiver receives analysis data indicating, for example, that the subject has been absent for a long time, that the subject has not been seen moving for a long time, that the door to the subject's dwelling has not been unlocked for a long time, or that the door to the subject's dwelling has not been opened or closed for a long time, they can take action such as visiting the subject's dwelling and speaking to them, or calling the subject. Therefore, a caregiver can take action towards the subject based on real-time analysis data received through the present invention, for example. The lighting device of the present invention can also be called a lighting device for detecting biological movement, for example, as it also functions as a biological movement detection device.

[0015] Next, the lighting device, biological movement detection system (hereinafter referred to as the detection system), and biological movement detection method (hereinafter referred to as the detection method) of the present invention will be described with examples using diagrams. The present invention is not limited or restricted in any way by the following embodiments. The descriptions in each embodiment can be used interchangeably with each other.

[0016] (Embodiment 1) An example of the lighting device and detection system using the same according to this embodiment will be described with reference to Figure 1. Figure 1 is a schematic diagram showing the overall configuration when the lighting device and detection system are used. The lighting device 10 is installed in the room of the subject 2's dwelling unit 1, and the magnetic detection device 40 is installed near the door 50 of the dwelling unit 1. Meanwhile, the caregiver 3, who wants to know the status of the subject 2, carries a terminal 30. The lighting device 10 and the terminal 30 can be connected via a communication network 20, and the lighting device 10 and the magnetic detection device 40 can communicate with each other. The communication method between the lighting device 10 and the magnetic detection device 40 is not limited, as will be described later, but wireless communication 40A will be used as an example below.

[0017] In dwelling unit 1, there are no particular restrictions on which rooms the lighting device 10 is installed in. Dwelling unit 1 generally has multiple rooms such as a bedroom, living room, kitchen, and toilet. According to the detection system of this embodiment, analytical data is obtained that indicates whether or not the subject 2 is inside dwelling unit 1 and whether or not they are moving around inside dwelling unit 1. For this reason, the lighting device 10 may be installed in all rooms, for example, or in rooms where the subject spends a long time (for example, the living room, bedroom, etc.).

[0018] The lighting device 10 can be, for example, ceiling-mounted or wall-mounted, with ceiling-mounted being preferred. By installing the lighting device 10 on the ceiling, for example, it becomes possible to detect biological information over a wider area.

[0019] In dwelling unit 1, the doors 50 to which the magnetic detection device 40 is to be installed include, for example, room doors and entrance doors, with the entrance door being preferred. The installation location of the magnetic detection device 40 on the door 50 is not particularly limited. In the present invention, when analyzing the locking and unlocking of the door 50, the installation location is, for example, a position where a change in magnetism due to switching between locking and unlocking can be detected, and when analyzing the opening and closing of the door 50, the installation location is, for example, a position where a change in magnetism due to switching between opening and closing the door 50 can be detected.

[0020] Door 50 is locked, for example, by the bolt of the deadbolt of door 50 engaging with the corresponding strike plate, and door 50 is unlocked by the deadbolt being removed from the strike plate. The locking and unlocking may be operated, for example, by a key or by a thumbturn. Opening and closing of door 50 is not limited to the aforementioned locking and unlocking, but also means opening and closing the door 50 for people to enter and exit.

[0021] The method for generating magnetic changes due to switching between locking and unlocking the door 50 and switching between opening and closing the door 50 is not particularly limited, and for example, a magnet can be used. Preferably, the magnet is placed in a position where the distance or angle to the magnetic detection device 40 changes when the door 50 is switched between locking and unlocking or when the door 50 is opened and closed. This makes it possible to generate magnetic changes when the door 50 is locked or unlocked or when the door 50 is opened and closed. As a specific example, Figure 2 shows a configuration in which the magnet is placed on the thumbturn 51 of the door 50. Figure 2 is a schematic diagram showing the positional relationship between the thumbturn 51 of the door 50 and the magnetic detection device 40. In Figure 2, a magnet 52 is fixed to the thumbturn 51. As shown in Figure 2, for example, in the locked state (A), the thumbturn 51 is oriented horizontally, and in the unlocked state (B), the thumbturn 51 is oriented vertically. Furthermore, the distance of the magnet 52 fixed to the thumbturn 51 from the magnetic detection device 40 changes between the locked state (A) and the unlocked state (B). Therefore, the magnetic detection device 40 can detect the magnetic change caused by the switching between locking and unlocking by the thumbturn 51.

[0022] Furthermore, the device is not limited to this, and for example, a magnet 52 may be fixed to the door 50, and the magnetic detection device 40 may be placed on the door 50 frame side. In this case, when the door 50 is opened, the magnet 52 moves away from the door 50 frame, and when the door 50 is closed, the magnet 52 moves closer to the door 50 frame. Therefore, the magnetic detection device 40 can detect the change in magnetism caused by the opening and closing of the door 50.

[0023] As mentioned above, the communication method between the lighting device 10 and the magnetic detection device 40 is not particularly limited, and for example, wireless communication 40A can be used. In this case, for example, the lighting device 10 has a wireless communication unit as a communication unit with the magnetic detection device 40, and the magnetic detection device 40 has a wireless communication unit as a communication unit with the lighting device 10.

[0024] The communication network 20 connecting the lighting device 10 and the terminal 30 can, for example, be a known communication network. The communication method is not particularly limited and may be wired or wireless, for example, an internet connection, a telephone line, etc.

[0025] Terminal 30 only needs to be connectable to the lighting device 10 via the communication network 20, and for example, it may have a communication module. Terminal 30 may also have, for example, a CPU (central processing unit), an output unit, an input unit, a memory unit, etc., each of which may be connected by an interface (I / F). The output unit is, for example, a display unit such as a display, an audio output unit, etc. Terminal 30 is not particularly limited, and for example, a portable terminal can be cited. Specific examples of the portable terminal include smartphones, tablets, mobile phones, and wearable devices. Examples of the wearable device include a wristwatch type, glasses type, ring type, shoe type, pocket type, pendant type, etc.

[0026] Next, an example of the lighting device 10 of this embodiment will be described using Figure 3. Figure 3 is a block diagram showing an example of the lighting device 10. For convenience, in Figure 3, as in Figure 1, connections to the terminal 30 via a communication network and connections to the magnetic detection device 40 via wireless communication are shown. The lighting device 10 has a lighting device body 11. The lighting device body 11 has a lighting unit 101, and further includes a biometric information detection unit 102, a wireless communication unit 103 which is an example of the communication unit, a processing unit 104, and an output unit 105 to an external terminal.

[0027] The lighting device 10 consists of a lighting device body 11 and a cover member (not shown) that covers the lighting unit 101, etc., of the lighting device body 11. That is, the lighting device body 11 represents the basic structure of a lighting device, and includes, for example, a lighting unit 101 containing a light source, a power supply unit, etc., for functioning as a lighting device. The configuration and structure of the lighting device body 11 are not particularly limited, and as described above, it is sufficient that it functions as a lighting device and can also be equipped with a bio-information detection unit 102, a wireless communication unit 103, a processing unit 104, and an output unit 105. Furthermore, the form of the lighting device body 11 is not particularly limited, and examples include ceiling lights and pendant lights that are attached to a ceiling hook. The type of light source of the lighting unit 101 is not particularly limited, and examples include LEDs, organic ELs, etc. In the lighting device 10, for example, the biological information detection unit 102, the wireless communication unit 103, the processing unit 104, and the output unit 105 may be housed between the substrate on the installation side of the lighting device body and a diffusion cover (not shown) provided on the light-illuminating side. The substrate is, for example, a main substrate for fixing a light source such as an LED, a power supply circuit, etc., and the diffusion cover is, for example, a cover that diffuses the light emitted from the light source to reduce glare. The power supply unit is, for example, connected directly or indirectly to an external power supply and supplies power to the lighting unit 101, the biological information detection unit 102, the wireless communication unit 103, the processing unit 104, and the output unit 105.

[0028] Furthermore, when lighting is not needed, such as during the daytime, the biometric information detection unit 102, wireless communication unit 103, processing unit 104, and output unit 105 can be operated while the lighting unit 101 remains switched off, for example, by installing an automatic lighting device.

[0029] The bio-information detection unit 102 detects bio-information in the space where the lighting device body 11 is installed. The type of bio-information detection unit 102 is not particularly limited, as long as it can detect bio-information indicating the presence of a human body. Specific examples of the bio-information detection unit 102 include, for example, a human presence sensor or a camera. The human presence sensor is preferred for the bio-information detection unit 102 because, for example, it is inexpensive and does not require complex information processing. The human presence sensor is, for example, a pyroelectric sensor or an infrared sensor, and the infrared sensor may be, for example, an array type with multiple sensors installed. The human body emits infrared radiation. Therefore, for example, if the human presence sensor detects infrared radiation in the space, the processing unit 104, described later, can analyze the presence or absence of a living organism and its movement in the space from the bio-information detection data. In the case of a camera, if an image of the space is captured, the processing unit 104, described later, can analyze the presence or absence of a living organism and its movement in the space from the captured image data (the bio-information detection data).

[0030] As mentioned above, the lighting device 10 is preferably installed on the ceiling, for example, but may also be installed on the wall or under the floor. The biometric information detection unit 102 mounted on the lighting device 10 can detect biometric information within the region 4 enclosed by the dotted circle in Figure 1. Region 4 will also be referred to as the detection region 4 below. The size of the detection region 4 is not particularly limited and can be set appropriately depending on, for example, the type and number of biometric information detection units 102 mounted on the lighting device 10, the height of the ceiling on which the lighting device 10 is installed, the size of the room, etc. For one lighting device 10, the detection region 4 can be estimated to be a 1K apartment, for example, based on a typical floor plan for a single elderly person.

[0031] In the lighting device 10, the communication unit for the magnetic detection device 40 is not particularly limited, as described above, and a wireless communication unit 103 is an example. The wireless communication unit 103 can communicate wirelessly with the magnetic detection device 40, which is an external device separate from the lighting device 10. The wireless communication unit 103 receives magnetic detection data transmitted from the magnetic detection device 40 and transmits it to the processing unit 104.

[0032] In the lighting device 10, the biometric information detection data detected by the biometric information detection unit 102 is sent to the processing unit 104 and analyzed as described later. Communication between the biometric information detection unit 102 and the processing unit 104 is not particularly limited and may be, for example, communication between circuits via a bus or wireless communication via a wireless communication unit. In the latter case, the wireless communication unit 103 can be used as the wireless communication unit. The wireless communication unit 103 can communicate wirelessly with the processing unit 104 located within the same lighting device 10. The wireless communication unit 103 then transmits the biometric information detection data detected by the biometric information detection unit 102 to the processing unit 104. The wireless communication unit 103 is not particularly limited and only needs to be able to wirelessly connect the biometric information detection unit 102 and the processing unit 104, which are located within the same lighting device 10.

[0033] The wireless communication method of the wireless communication unit 103 is not particularly limited and may include, for example, IEEE (The Institute of Electrical and Electronics Engineers, Inc.) 802.15.1 and IEEE 802.15.4. IEEE 802.15.1 is, for example, a standard related to Bluetooth®, and IEEE 802.15.4 is, for example, a standard related to ZigBee®. Other examples include RFID, infrared communication (IrDA), and UWB.

[0034] The processing unit 104 analyzes the presence or absence of a living organism and whether or not the living organism has moved, based on the biological information detection data. As described above, if the biological information detection data is infrared detection data, for example, infrared data in an unoccupied state is used as a threshold, and if detection data showing a significant difference from the threshold is obtained, it can be determined that a person is present in the space. Furthermore, if the detection data showing a significant difference from the threshold changes over time, it can be determined that a person has moved in the space. The lighting device body may further have, for example, a storage unit, and the storage unit may store information such as the threshold as evaluation criterion information.

[0035] Furthermore, the processing unit 104 analyzes the locking and unlocking of the door 50, or the opening and closing of the door 50, based on the received magnetic detection data. As described above, for example, by placing the magnetic detection device 40 and the magnet near the door 50, a magnetic change can be generated by switching the door 50 between locking and unlocking, or by opening and closing the door 50. For this reason, for example, the magnetic change due to switching the door 50 between locking and unlocking, or the magnetic change due to opening and closing the door 50, can be set as evaluation criterion information, and the locking and unlocking of the door 50, or the opening and closing of the door 50 can be determined by comparing the magnetic detection data with the evaluation criterion information. The storage unit may store the relationship between switching the door 50 between locking and unlocking and the magnetic change, and the relationship between opening and closing the door 50 and the magnetic change, as evaluation criterion information.

[0036] The processing unit 104 may be, for example, a CPU. In the lighting device 10, the processing unit 104 is preferably a small device because it is mounted on, for example, the main body of a typical lighting device. Examples of such small devices include small single-board computers, and a specific example is the Raspberry Pi®. The CPU is connected to other parts, for example, via an interface.

[0037] The output unit 105 transmits the analysis data obtained by the processing unit 104 to the external terminal 30 via the communication network 20. The output unit 105 may also be a transmitting / receiving unit that transmits information to the external terminal 30 and receives information from the external terminal 30. The output unit 105 may be, for example, a communication module.

[0038] The lighting device body 11 may further include, for example, a storage unit. The storage unit can store, for example, biological information detection data from the biological information detection unit 102, magnetic information detection data from the magnetic detection device 40, and analysis data from the processing unit 104.

[0039] When the external terminal 30 receives the analysis data from the output unit 105 of the lighting device 10 via the communication network 20, the external terminal 30 outputs the analysis data to the output unit, for example. If the output unit is a display unit such as a screen, the analysis data may be displayed on the display unit, or if the output unit is an audio output unit such as a speaker, the analysis data may be emitted as sound. This allows the caregiver 3 to understand the condition of the subject 2 from the external terminal 30.

[0040] If the external terminal 30 has the display unit, the analysis data can be displayed as follows, for example. Note that this is an example and does not limit the present invention. The following example uses a smartphone as the external terminal 30 and the living room of dwelling unit 1 as the installation location of the lighting device 10. Figure 8 is a schematic diagram showing an example of the display of analysis data on the display unit 31 of the external terminal (smartphone) 30. As shown in Figure 8, the display unit 31 of the smartphone 30 displays the analysis results 32 and their reception time 33 in chronological order. The analysis results 32 are displayed as messages such as, for example, "Activity in the living room could not be confirmed at XX:△△" or "The unlocking of the front door could not be confirmed at XX:△△". In addition, if the movement of subject 2 is confirmed, a message such as "Activity in the living room was confirmed at XX:△△" is displayed, and if the unlocking of the front door is confirmed, a message such as "The unlocking of the front door was confirmed at XX:△△" is displayed. In addition, the display unit 31 may also display the dwelling information and name of subject 2, as shown in Figure 8.

[0041] The magnetic detection device 40 is a device installed near the door 50 of a dwelling unit 1, as shown in Figure 1, and includes a magnetic sensor 401 and a wireless communication unit 402 as an example of a communication unit.

[0042] The magnetic sensor 401 is a sensor that detects magnetism, and in the present invention, for example, it detects magnetic changes caused by locking and unlocking the door 50, or magnetic changes caused by opening and closing the door 50. For example, a Hall element can be used as the magnetic sensor 401.

[0043] The communication unit only needs to be able to communicate with the lighting device 10, and as mentioned above, the wireless communication unit 402 can be an example. The wireless communication unit 402 is capable of wireless communication with the lighting device 10, and its wireless communication method is not particularly limited and is the same as described above.

[0044] (Variation 1) The lighting device 10 may further include a detection control unit 106, as shown in the block diagram of Figure 4. The detection control unit 106 controls the start and stop of detection by the biological information detection unit 102. The detection control unit 106 is, for example, a CPU. In Figure 4, for convenience, the connection to the terminal 30 via a communication network and the connection to the magnetic detection device 40 via wireless communication are shown, similar to Figure 3.

[0045] The detection control unit 106 controls the start and stop of detection by the biological information detection unit 102. For example, instead of performing continuous detection at all times, detection can be performed only when necessary or intermittently, thereby reducing costs such as electricity bills and saving on the amount of recorded data. The detection control unit 106 can, for example, start detection by the biological information detection unit 102 at any time interval, and stop detection by the biological information detection unit 102 after any time has elapsed since the start of detection.

[0046] When the biological information detection unit 102 obtains biological information detection data over time, the processing unit 104 analyzes, for example, the presence or absence of a living organism and whether or not the living organism is moving, from the biological information detection data received over time. By using biological information detection data over time, it is possible to analyze in more detail, for example, whether the subject is not in the room, whether the subject is in the room but not moving, or whether the subject is moving.

[0047] (Modification 2) The lighting device 10 may have, for example, an output unit 105 which is a transmitting / receiving unit 405, as shown in the block diagram of Figure 5, and may also have an alert unit 107. As described above, the transmitting / receiving unit 405 transmits information to an external terminal 30 via a communication network 20 and receives information from the external terminal 30. The alert unit 107 also issues an alert when it receives alert information transmitted from the terminal 30 to the transmitting / receiving unit 405. The alert unit 107 is, for example, a speaker, and the alert may be, for example, a siren, a pre-set message, or a real-time message from the caretaker 3, as described later.

[0048] If the caregiver 3 receives analysis data via the communication network 20, such as that the subject 2 is not moving, that the door 50 has not been unlocked for a long time, or that the door 50 has not been opened for a long time, the caregiver 3 can send a message to the lighting device 10 in real time via the communication network 20 from the terminal 30. When the transmitting / receiving unit 405 of the lighting device 10 receives the message, the alert unit 107 of the lighting device 10 can send the message to the dwelling unit 1.

[0049] Next, the detection method of this embodiment will be explained using the flowchart in Figure 6. The detection method of this embodiment is carried out as follows, for example, using the detection system of this embodiment shown in Figure 1 and the lighting device 10 shown in Figures 3 to 5. In the flowchart in Figure 6, the steps enclosed in thick lines (S300, S301) are steps performed by the magnetic detection device 40, and the others are steps performed by the lighting device 10. Note that the detection method of this embodiment is not limited to the use of the detection system in Figure 1 and the lighting device 10 in Figures 3 to 5. Illumination, detection of biological information, and detection of magnetic changes will be explained in order, but as will be described later, the order of these steps is not restricted.

[0050] The lighting device 10 illuminates the space of the room in which the lighting device 10 is installed using the lighting device body (S100).

[0051] Furthermore, the lighting device 10 detects biological information in the space of the room where the lighting device 10 is installed using the biological information detection unit 102 (S200). The wireless communication unit 103 of the lighting device 10 then transmits the detected biological information detection data to the processing unit 104 of the lighting device 10 (S201), which receives it. Next, the processing unit 104 of the lighting device 10 analyzes the presence or absence of living organisms and the presence or absence of movement of living organisms in the space based on the received biological information detection data (S202). The analysis data obtained by the processing unit 104 of the lighting device 10 is then transmitted to the external terminal 30 via the communication network 20 (S203). This process (S200) to (S203) is repeated, for example, continuously or intermittently.

[0052] On the other hand, the magnetic detection device 40 uses a magnetic sensor 401 to detect magnetic changes caused by locking and unlocking the door of the dwelling unit 1, or by opening and closing the door (S300), and transmits the detected magnetic detection information from the magnetic detection device 40 to the processing unit 104 of the lighting device 10 using the wireless communication unit 402 (S301). The lighting device 10 then uses its wireless communication unit 103 to receive the magnetic detection information transmitted from the magnetic detection device 40 and transmits it to the processing unit 104 of the lighting device 10. Next, when the processing unit 104 of the lighting device 10 receives the magnetic detection information, it analyzes the locking and unlocking of the door 50, or the opening and closing of the door 50, based on the received magnetic detection data (S302). The processing unit 104 of the lighting device 10 then transmits the analysis data obtained to the external terminal 30 via the communication network 20 (S203). Steps (S300), (S302), and (S203) are repeated, for example, continuously or intermittently.

[0053] In this embodiment, the lighting process (S100), the biological information process (S200) to (S202), the magnetic change process (S300) to (S302), and (S203) can, for example, be carried out in parallel. Furthermore, the lighting process (S100) is optional, and other processes may be carried out even if this process (S100) is not performed. In other words, with respect to the lighting device 10, other processes may be carried out regardless of whether the lighting is ON or OFF.

[0054] According to this method, firstly, in the first form, the need to check on the safety of a person residing in a dwelling can be detected by detecting the movement of living organisms within the dwelling. For example, in the above step (S202), the presence or absence of living organisms and the presence or absence of movement of living organisms can be analyzed over time. If there is no change, the result of determining that the safety of the person (resident) 2 in the dwelling 1 where the lighting device 10 is installed needs to be checked can be transmitted as analysis data to the external terminal 30 of the monitor 3 via the communication network 20. If there is a change, the result of determining that the safety of the person 2 does not need to be checked can be transmitted as analysis data to the external terminal 30 of the monitor 3 via the communication network 20. Therefore, upon receiving the former transmission result, the monitor 3 can take further concrete safety check actions, such as going to the dwelling 1 and speaking to the person 2, or calling the person 2. On the other hand, if the latter transmission result is received, the caregiver 3 can, for example, decide that a safety check is unnecessary and omit going to the residence 1 of the subject 2 or making a phone call to the subject 2.

[0055] Furthermore, according to the method described above, in a second form, for example, by detecting the locking / unlocking of a door or the opening and closing of a door, it is possible to detect from a different perspective than in the first form whether or not it is necessary to check on the safety of the person residing in the dwelling unit. For example, in step (S302), the locking / unlocking of a door or the opening and closing of a door is analyzed, and if there is no change in the locking / unlocking of the door or no change in the opening and closing of the door for a long period of time, the result of determining that it is necessary to check on the safety of the person (resident) 2 in the dwelling unit 1 where the lighting device 10 is installed can be transmitted as analysis data to the external terminal 30 of the monitor 3 via the communication network 20. Also, if there is a change, the result of determining that it is unnecessary to check on the safety of the person 2 can be transmitted as analysis data to the external terminal 30 of the monitor 3 via the communication network 20. Therefore, upon receiving the former transmission result, the monitor 3 can take further specific safety check actions, for example, by going to the dwelling unit 1 and speaking to the person 2, or by calling the person 2. On the other hand, if the latter transmission result is received, the caregiver 3 can, for example, decide that a safety check is unnecessary and omit going to the residence 1 of the subject 2 or making a phone call to the subject 2.

[0056] Furthermore, the following determinations can also be made from the combination of the first and second embodiments. That is, for example, if in step (S202) there is no change over time regarding the presence or absence of a living organism and the movement of a living organism, and in step (S302) the analysis indicates that the door is locked and unlocked or the door is opened and closed, the determination that the safety of the subject needs to be confirmed may be transmitted as analysis data to the external terminal via the communication network. This is because if there is no change in the living organism but there is a change in the locking / unlocking or opening and closing of the door, for example, an intruder may be suspected. On the other hand, if in step (S202) there is a change over time regarding the presence or absence of a living organism and the movement of a living organism, the determination that the safety of the subject does not need to be confirmed may be transmitted as analysis data to the external terminal via the communication network. This is because it can be determined that the subject is able to move. Furthermore, if movement of a living being is detected within a dwelling unit, followed by the locking of the unit, and then no further movement within the unit is detected for an extended period, it is highly likely that the resident is out or traveling, thus reducing the need for a safety check.

[0057] Furthermore, as shown in Modification 2, if the lighting device 10 also has an alert unit 107, the steps shown in the flowchart of Figure 7 can be performed. That is, when the caregiver 3 receives analysis results on the terminal 30 indicating that the safety of the subject 2 needs to be checked, the caregiver 3 uses the terminal 30 to send alert information to the lighting device 10. The alert information may be, for example, a real-time voice message from the caregiver 3, a siren, a pre-set message, etc. When the lighting device 10 receives the alert information via the transmitting / receiving unit 405 (S204), it sends the alert from the alert unit 107 (S205).

[0058] In this way, by enabling two-way information communication between the lighting device 10 installed in the dwelling unit 1 of the subject 2 and the terminal 30 carried by the caregiver 3, the caregiver 3 can, for example, use the terminal 30 to send a message or siren to the subject 2 to confirm their safety. The alert may also be, for example, an alert notifying the occurrence of a disaster. Even if a disaster occurs in the vicinity of the dwelling unit, the subject 2 may not be aware of it. In such cases, by sending a disaster alert, the subject 2 can be notified of the disaster and encouraged to evacuate.

[0059] As described above, the lighting device 10 functions as a light source and also detects the movement of living organisms and the locking, unlocking, or opening / closing of doors. The primary function of lighting, the detection of living organism movement, and the locking, unlocking, or opening / closing of doors may, for example, be performed in parallel, or one of them may be stopped while the others are being performed.

[0060] The lighting device 10 is powered, for example, by turning on the main power supply (e.g., wall power supply). Therefore, regardless of whether the lighting unit 101 of the lighting device body is activated or not, it is possible to activate the biometric information detection unit 102, the wireless communication unit 103, the processing unit 104, and the output unit 105. However, there are cases where the detection of the subject is necessary regardless of whether the main power supply is ON or OFF. For this reason, it is preferable that the lighting device 10 further includes at least one of a power storage unit and a battery unit, so that the detection of the subject can be performed regardless of whether the main power supply is ON or OFF. By including the power storage unit or the battery unit in this way, for example, even when the main power supply is OFF, it is possible to supply power from the power storage unit or the battery unit to the biometric information detection unit 102, the wireless communication unit 103, the processing unit 104, and the output unit 105, and activate them.

[0061] Even if the caregiver requests the subject to keep the main power switch ON at all times, if the subject is elderly or otherwise, they may turn off the main power switch instead of using a remote control when turning off the lights from the lighting device 10. Furthermore, a fuse may blow due to an earthquake, fire, or other disaster, causing the main power switch to turn OFF regardless of the subject's wishes. However, with the lighting device 10 in this configuration, even if the main power switch is turned OFF, detection becomes possible through power supply from a backup power source such as the energy storage unit or battery unit, enabling safer and more reliable monitoring. In order to keep the main power switch ON at all times, a cover may be attached to the wall power supply (main power switch) in the room of the dwelling where the lighting device of the present invention is installed to prevent accidental ON / OFF switching.

[0062] In this invention, the target individuals are exemplified as the elderly, disabled persons, and sick persons, but are not limited thereto. This invention can be used in dwellings where a person who is a concern for the caregiver resides, and where the caregiver is worried about the person being alone in the dwelling. Specific examples of such persons include children, pets, and dementia patients with a tendency to wander. Normally, children do not live alone in dwellings, but for example, when parents are absent for work, shopping, or medical appointments, children may be alone in the dwelling. In such cases, the lighting device, detection system, and detection method of this invention are useful. Furthermore, for example, if it is not necessary to monitor the dwelling tenant themselves, but there are persons who require monitoring at certain times of the day, the detection control unit in the lighting device of this invention may, for example, perform detection by the biometric information detection unit in the lighting device of this invention only during the necessary time periods, and stop detection during other times. This can reduce, for example, the cost and power consumption associated with detection by the biometric information detection unit.

[0063] [Embodiment 2] The program of this embodiment is a program that can be executed on a computer, which implements the detection method of the above embodiment. The detection method of the present invention can be realized by, for example, installing and executing the program of this embodiment on a computer. In this case, the computer's CPU functions, for example, as the processing unit and optionally as the detection control unit. The program of this embodiment may also be recorded on a storage device such as a computer-readable recording medium. The recording medium is not particularly limited and includes, for example, read-only memory (ROM), hard disk (HD), optical disk, floppy disk (FD), etc.

[0064] Although the present invention has been described above with reference to embodiments, the present invention is not limited to the above embodiments. Various modifications to the configuration and details of the present invention can be understood by those skilled in the art within the scope of the present invention. [Industrial applicability]

[0065] According to the present invention, for example, by simply replacing the lighting equipment that is essential in a dwelling unit, it is possible to perform normal lighting functions while simultaneously detecting the movement of living beings and the locking / unlocking or opening and closing of doors, and outputting the results to a person outside the dwelling unit. For this reason, even if the resident is an elderly person living alone, for example, the landlord can easily find out whether the resident is in the room or moving around, making it possible to prevent or detect deaths in isolation at an early stage.
