[0003] [Patent Document 1] Japanese Patent Publication No. 2023-101135 Summary of the Invention [Problem to be solved by the invention]

[0004] Periodic inspections of emergency lights and emergency lighting fixtures are required by the Fire Service Act, the Building Standards Act, and other laws. The lighting fixture of Patent Document 1 automatically performs periodic inspections and notifies the user of the inspection results without the user having to initiate the inspection. Here, it is assumed that when an abnormality is detected in the inspection results, the user may not notice the notification. In this case, even if the next inspection is performed and the user is notified again that an abnormality has been detected in the same manner as the previous inspection, the user may not notice the notification.

[0005] The present disclosure aims to provide a lighting device that makes it easier for a user to notice abnormalities in a storage battery. [Means for solving the problem]

When a trigger to start an inspection occurs, the control device performs an inspection in response to the trigger if the memory unit does not store any previous inspection results indicating an abnormality in the storage battery. If an abnormality in the storage battery is detected during this inspection, the control device issues a first notification to notify of an abnormality in the storage battery. If the memory unit stores any previous inspection results indicating an abnormality in the storage battery, the control device issues a second notification by means different from the first notification.

[0007] The lighting device according to the present disclosure includes a light source unit, a storage battery that supplies power to the light source unit, a control device that inspects the storage battery by discharging the storage battery, and a memory unit that stores the inspection results of the inspection, and when an abnormality in the storage battery is detected during the current inspection, the control device issues a first notification to notify of the abnormality in the storage battery if the memory unit does not store previous inspection results that indicate an abnormality in the storage battery, and issues a second notification by means different from the first notification if the memory unit stores previous inspection results that indicate an abnormality in the storage battery.

[0008] The lighting device according to the present disclosure includes a light source unit, a storage battery that supplies power to the light source unit, and a control device that inspects the storage battery by discharging the storage battery, and if an abnormality in the storage battery is detected during the inspection, the control device issues a first notification to notify the user of the abnormality in the storage battery, and if the abnormality in the storage battery is not resolved after the first notification is initiated, the control device issues a second notification by a means different from the first notification. [Effects of the Invention]

[0011] The lighting device according to each embodiment will be described with reference to the drawings. The same or corresponding components are designated by the same reference numerals, and the repeated description may be omitted.

[0012] Embodiment 1 Fig. 1 is a perspective view of a lighting device 1 according to embodiment 1. Fig. 2 is a perspective view showing an exploded state of the lighting device 1 according to embodiment 1. Fig. 3 is a block diagram showing the configuration of the lighting device 1 according to embodiment 1. The lighting device 1 includes a light source unit 2, a storage battery 3, a power supply device 4, a notification unit 5, a light receiving unit 6, and an inspection switch 7.

[0013] The light source unit 2 has a light-emitting section 21 and an optical member 22. When the supply of power from an external power source (not shown) is stopped, the light source unit 2 receives power from the power supply device 4 and lights up. The light-emitting section 21 is a light-emitting element such as an LED that receives power and emits light. The optical member 22 is arranged to cover the light-emitting section 21, and controls the light distribution of the light emitted from the light-emitting section 21. The optical member 22 is a lens made of glass, resin, or the like.

[0014] The storage battery 3 supplies power to the light source unit 2 via a power supply device 4. The storage battery 3 is, for example, a rechargeable secondary battery. The storage battery 3 is, for example, a nickel-cadmium battery, a nickel-metal hydride battery, a lithium-ion battery, an all-solid-state battery, etc. The storage battery 3 is connected to the power supply device 4.

[0015] The power supply device 4 has a charging circuit 41, a lighting circuit 42, a detection unit 43, an inspection unit 44, a determination unit 45, a memory unit 46, a control unit 47, and a timing unit 48. The charging circuit 41 converts AC voltage supplied from an external power supply (not shown) into DC voltage to charge the storage battery 3. The lighting circuit 42 controls the current discharged from the storage battery 3 and supplies it to the light source unit 2, thereby lighting the light source unit 2.

[0016] The detection unit 43 detects that the power supplied from the external power source has stopped. When the detection unit 43 detects that the power supply from the external power source has stopped, the charging circuit 41 stops the supply of power to the storage battery 3. Furthermore, the lighting circuit 42 supplies the current supplied from the storage battery 3 to the light source unit 2 to light the light source unit 2.

[0017] The inspection unit 44 inspects whether the lighting device 1 can be turned on for an appropriate period of time in an emergency by using a simulated power outage. That is, the inspection unit 44 inspects the storage battery 3 by discharging it. Inspection of emergency lights is stipulated in the Fire Service Act. The inspection cycle for emergency lights is six months. Furthermore, when inspecting emergency lights, the light source unit 2 must be turned on for 20 or 60 minutes using the power from the storage battery 3. Inspection of emergency lighting devices is stipulated in the Building Standards Act. The inspection cycle for emergency lighting devices is six to twelve months. Furthermore, when inspecting emergency lighting devices, the light source unit 2 must be turned on for 30 or 60 minutes using the power from the storage battery 3. Hereinafter, the lighting time during inspection may be referred to as the inspection time.

[0018] The inspection unit 44 can start an inspection using, for example, the following four types of triggers. The first is when the inspection switch 7 is pressed. The second is when the light receiving unit 6 receives an inspection start signal from an external terminal such as a remote control (not shown). The third is when an inspection signal is received from a controller (not shown) that controls the lighting device 1. The controller is connected to multiple lighting devices 1 and controls each lighting device 1. The controller stores the inspection cycle, schedule, etc. of each lighting device 1. The controller sends an inspection start signal to the lighting device 1 when the timer time or real time obtained from an external device reaches the inspection cycle. The fourth is when the time on the timer unit 48, which is a timer built into the lighting device 1, or real time obtained from an external device reaches the inspection cycle. In this case, the lighting device 1 stores the inspection start cycle or the date and time to perform the inspection in the memory unit 46.

[0019] When the inspection unit 44 starts the inspection, it stops the supply of power from the charging circuit 41 to the storage battery 3. Furthermore, the inspection unit 44 causes the lighting circuit 42 to supply current from the storage battery 3 to the light source unit 2, thereby lighting up the light source unit 2. Note that during the inspection, it is also possible to discharge the storage battery 3 into a pseudo resistor or the like without supplying current to the light source unit 2. In this case, the power of the storage battery 3 is converted into heat in the pseudo resistor, and the charge capacity of the storage battery 3 can be confirmed.

[0020] When the inspection is completed, the inspection unit 44 stops the supply of current from the storage battery 3 to the light source unit 2 by the lighting circuit 42. The inspection unit 44 also causes the charging circuit 41 to resume charging the storage battery 3.

[0021] When the inspection time has elapsed since the start of inspection, the determination unit 45 determines whether the battery voltage of the storage battery 3 is higher or lower than the discharge reference voltage. If the battery voltage of the storage battery 3 is higher than the discharge reference voltage, the storage battery 3 is determined to be normal. If the battery voltage of the storage battery 3 is lower than the discharge reference voltage, the storage battery 3 is determined to be abnormal. Here, the discharge reference voltage is a reference value of the battery voltage of the storage battery 3 at which the light emitted from the light source unit 2 satisfies the optical characteristics required by standards based on the Fire Service Act or the Building Standards Act. In other words, if the battery voltage of the storage battery 3 is lower than the discharge reference voltage after the inspection time has elapsed since the start of lighting, the determination unit 45 determines that the storage battery 3 does not meet the capacity required by the standards.

[0022] The storage unit 46 is configured with at least one storage device such as a ROM (Read Only Memory) or a RAM (Random Access Memory). The storage unit 46 stores, for example, an inspection schedule, an inspection interval, and inspection results. The storage unit 46 may have calendar information into which inspection dates or times are input as the inspection schedule. The inspection schedule or inspection interval may be stored in the storage unit 46 in advance, or may be set after the lighting device 1 is installed. In the present embodiment, the storage unit 46 is described as being included in the lighting device 1, but this is not limiting. The storage unit 46 may also be provided in an external terminal, a server on a network, or the like, as long as it is capable of communicating with the lighting device 1.

[0023] The memory unit 46 stores the inspection results of the inspection determined by the determination unit 45 after the inspection performed by the inspection unit 44. The memory unit 46 may store the inspection results and the time when the inspection was performed. The memory unit 46 may store the inspection results for multiple inspections.

[0024] The control unit 47 can be configured with, for example, a microcomputer. The control unit 47 causes the notification unit 5 to issue a notification based on the determination made by the determination unit 45. The control unit 47 changes the notification means of the notification unit 5, as will be described later, based on the past inspection results stored in the memory unit 46.

[0025] The timer 48 counts time. The timer 48 may count the inspection period, the inspection time, etc.

[0026] The detection unit 43, the inspection unit 44, the determination unit 45, the control unit 47, and the timing unit 48 correspond to the control device of this embodiment. The control device can be configured with at least one processing device. The processing device is, for example, a processor, a microcomputer, or the like. The storage unit 46 may store a program for the control device to execute the inspection and notification.

[0027] The notification unit 5 notifies, by means of a display or the like, the state of the light source unit 2, the state of the inspection, the inspection result performed by the inspection unit 44 and judged by the judgment unit 45, etc. When notifying that an inspection is in progress, the notification unit 5 may change the notification method depending on the difference in the inspection trigger.

[0028] The light receiving unit 6 is, for example, an infrared sensor. The light receiving unit 6 receives a signal to start inspection from an external terminal (not shown). The inspection switch 7 is a switch that can be pressed. When the inspection switch 7 is pressed, an inspection is performed.

[0029] Next, the inspection and notification operations of the lighting device 1 will be described in detail. Fig. 4 is a flowchart showing the operation of the lighting device 1 according to the first embodiment. First, the inspection unit 44 starts the inspection. That is, it is assumed that the inspection unit 44 detects that a trigger for starting the inspection has occurred. In response to this, the control unit 47 checks whether a past inspection result indicating an abnormality in the storage battery 3 is stored in the storage unit 46 (step 1).

[0030] If the memory unit 46 does not store any past inspection results indicating an abnormality in the storage battery 3, the inspection unit 44 performs an inspection in response to a trigger. That is, the inspection unit 44 stops charging the storage battery 3 by the charging circuit 41, and starts supplying power from the storage battery 3 to the light source unit 2 by the lighting circuit 42, thereby lighting up the light source unit 2 (step 2). When the inspection time has elapsed since lighting started, the determination unit 45 determines whether the battery voltage of the storage battery 3 is equal to or higher than the discharge reference voltage (step 3).

[0031] If the battery voltage of the storage battery 3 is equal to or greater than the discharge reference voltage, it is determined that there is no abnormality. If the battery voltage of the storage battery 3 is lower than the discharge reference voltage, it is determined that there is an abnormality. If there is an abnormality, the control unit 47 causes the notification unit 5 to issue a first notification (step 4).

[0032] In step 1, if the memory unit 46 stores past inspection results indicating an abnormality in the storage battery 3, the control unit 47 causes the alarm unit 5 to issue a second alarm using a means different from the first alarm (step 5).

[0033] In this way, when a trigger to start an inspection occurs, the control device of this embodiment performs an inspection in response to the trigger unless the memory unit 46 stores past inspection results indicating an abnormality in the storage battery 3. If an abnormality in the storage battery 3 is detected during the current inspection in response to the trigger, the control device issues a first notification to notify the user of the abnormality in the storage battery 3. Furthermore, if the memory unit 46 stores past inspection results indicating an abnormality in the storage battery 3, the control device issues a second notification by a means different from the first notification.

[0034] In this embodiment, after the start of inspection, if the memory unit 46 contains past inspection results indicating an abnormality in the storage battery 3, the inspection unit 44 does not perform the inspection, and the control unit 47 causes the notification unit 5 to issue a second notification by means different from the first notification. This is not a limitation, and the inspection unit 44 may turn on the light source unit 2 and perform the inspection even if past inspection results indicating an abnormality in the storage battery 3 are stored. In this case, if the control unit 47 determines that an abnormality exists, it issues the second notification by means different from the first notification. An example of such control will be described with reference to FIG. 5.

[0035] 5 is a flowchart showing the operation of the lighting device 1 according to the modification of the first embodiment. First, the inspection unit 44 starts inspection. The inspection unit 44 stops charging of the storage battery 3 by the charging circuit 41 and starts supplying power from the storage battery 3 to the light source unit 2 by the lighting circuit 42, thereby lighting the light source unit 2 (step 101). When the inspection time has elapsed since lighting started, the determination unit 45 determines whether the battery voltage of the storage battery 3 is equal to or higher than the discharge reference voltage (step 102).

[0036] If the battery voltage of the storage battery 3 is equal to or greater than the discharge reference voltage, it is determined that there is no abnormality. If the battery voltage of the storage battery 3 is lower than the discharge reference voltage, it is determined that there is an abnormality. If there is an abnormality, the control unit 47 checks whether a past inspection result indicating an abnormality in the storage battery 3 is stored in the memory unit 46 (step 103).

[0037] If the memory unit 46 does not contain any past inspection results indicating an abnormality in the storage battery 3, the control unit 47 causes the notification unit 5 to issue a first notification (step 104). If the memory unit 46 contains past inspection results indicating an abnormality in the storage battery 3, the control unit 47 causes the notification unit 5 to issue a second notification by a means different from the first notification (step 105).

[0038] In this way, when an abnormality in the storage battery 3 is detected during the current inspection, the control device of this embodiment issues a first notification to notify of the abnormality in the storage battery 3 if the memory unit 46 does not store past inspection results indicating an abnormality in the storage battery 3. Furthermore, when an abnormality in the storage battery 3 is detected during the current inspection, the control device issues a second notification by means different from the first notification if the memory unit 46 stores past inspection results indicating an abnormality in the storage battery 3.

[0039] Next, the effects of this embodiment and the modified example will be described. Even if an abnormality in the storage battery 3 is notified based on the inspection results, there is a possibility that the user will not notice the notification. In contrast, according to this embodiment, the method of notifying the abnormality is changed from a first notification to a second notification based on whether or not past inspection results are stored. This makes it easier for the user to notice an abnormality in the storage battery 3.

[0040] The past inspection results referred to by the control unit 47 may be the results of an inspection prior to the current inspection. The past inspection results may be, for example, the results of the previous inspection.

[0041] A first notification unit that issues the first notification and a second notification unit that issues the second notification may be provided separately as the notification unit 5. Alternatively, a single notification unit 5 may issue the first notification and the second notification that includes information different from the first notification.

[0042] If the storage battery 3 is replaced while the notification unit 5 is issuing a notification indicating an abnormality in the storage battery 3, the inspection results stored in the memory unit 46 may be erased. As a result, if an abnormality is determined in the inspection of the replaced storage battery 3, the notification unit 5 will issue the first notification.

[0043] 6 to 9 are diagrams showing examples of the notification unit 5 according to the first embodiment. FIG. 6 shows an example in which the notification unit 5 is a plurality of monitor lamps 51 that emit different light colors. The monitor lamps 51 include, for example, an orange LED 511, a red LED 512, and a green LED 513. For example, the light colors of the lit or flashing monitor lamps 51 differ between the first notification and the second notification.

[0044] An example of the monitor lamp display is shown below. The orange LED 511 flashes during inspection and is off otherwise. The red LED 512 flashes when the light source has reached the end of its lifespan, lights up when there is an abnormality such as the light source being disconnected, damaged, or not lighting, and is off otherwise. The green LED 513 lights up normally, when the light source has reached the end of its lifespan, or when there is an abnormality such as the light source being disconnected, damaged, or not lighting, flashes when the storage battery 3 has reached the end of its lifespan, and is off otherwise.

[0045] Here, as an example, a state in which the orange LED 511 is off, the red LED 512 is off, and the green LED 513 is flashing is defined as the first alert. A lighting state of the monitor lamp 51 that is different from the first alert is defined as the second alert. The second alert is, for example, a state in which the orange LED 511 is flashing, the red LED 512 is flashing, and the green LED 513 is flashing. The first alert and the second alert may be in any lighting state in which the monitor lamp 51 is different. The number, color, combination, etc. of the monitor lamps 51 are not limited to the example in FIG. 6. The first alert and the second alert may be distinguished by the intensity of the light of the monitor lamp 51.

[0046] Furthermore, the lighting pattern of the monitor lamp 51 may be regular so that the user can distinguish between the first and second alerts. For example, the lighting interval of the monitor lamp 51 may be different between the first and second alerts. Also, the number of times the monitor lamp 51 flashes within a certain period of time may be different between the first and second alerts. For example, the monitor lamp 51 flashes once within a certain period of time for the first alert, and the monitor lamp 51 flashes twice within a certain period of time for the second alert. In this way, the number of flashes within a certain period of time may be used to enable the user to recognize whether the alert is the first or second alert. The user may be able to recognize whether the alert is the first or second alert based on the number of monitor lamps 51 that are lit or flashing, rather than the number of flashes.

[0047] Here, the distinction between the first and second notifications has been described, but the number of times the indicator flashes within a certain period of time or the number of monitor lamps 51 that light up or flash may be changed depending on the number of past inspection results that indicate an abnormality in the storage battery 3, which are stored in the memory unit 46. This allows the user to recognize the number of times an abnormality has been notified.

[0048] 7 shows an example in which the notification unit 5 is a sound generating unit 52 such as a speaker that generates sound. The first notification and the second notification may be notification by different sounds. For example, the first notification is a sound such as "beep," and the second notification is a sound including a message such as "battery abnormality." However, the first notification and the second notification may be notification by different sounds in volume or pitch.

[0049] The sound pattern may have a regularity so that the user can distinguish between the first and second alerts. For example, the first alert may be made by making the sound generation unit 52 emit a "beep" once within a certain period of time, and the second alert may be made by making the sound generation unit 52 emit a "beep beep" twice or repeatedly within a certain period of time. This may allow the user to recognize whether it is the first alert or the second alert.

[0050] Here, the distinction between the first and second alerts has been described, but the number of times the alert is issued within a certain period of time may be changed depending on the number of past inspection results indicating an abnormality in the storage battery 3 that are stored in the memory unit 46. This allows the user to recognize the number of times an abnormality has been alerted. Rather than being limited to the number of occurrences, the voice generation unit 52 may directly alert the number of times an abnormality has been alerted, such as "first time" or "second time."

[0051] 8 shows an example in which the notification unit 5 is a display unit 53 such as a liquid crystal screen that displays characters or images. The first notification and the second notification are, for example, notification using different characters or images. The first notification is, for example, a notification using characters such as "Storage battery abnormality," and the second notification is, for example, a notification using characters such as "Battery abnormality." The first notification and the second notification may be different in character size, character font, character color, or screen background color.

[0052] FIG. 9 shows an example in which the alarm unit 5 is a communication unit 54 capable of communicating with an external terminal, network, etc. The communication unit 54 has, for example, an infrared communication unit as a first alarm unit that issues a first alarm, and a radio wave communication unit other than infrared communication unit as a second alarm unit that issues a second alarm. The first alarm unit and the second alarm unit are each capable of transmitting inspection result data. In this way, the communication method or communication protocol of the communication unit 54 may be different for the first alarm and the second alarm. However, this is not limited to this, and the communication method of the communication unit 54 may be the same. The data transmitted from the communication unit 54 or the destination of the data from the communication unit 54 may be different for the first alarm and the second alarm.

[0053] Any electrical device capable of communication can be used as the destination of data from the communication unit 54. Examples of electrical devices include a personal computer, a mobile phone, a speaker, an AI speaker, a television, etc. When these electrical devices receive data from the communication unit 54, the inspection results are reported from the electrical devices.

[0054] The first and second notifications may be made by different means among the monitor lamp 51, sound from the sound generating unit 52, characters on the display unit 53, an image on the display unit 53, and data transmission by the communication unit 54. For example, one of the first and second notifications may be made by the monitor lamp 51, and the other may be made by sound. Furthermore, multiple means may be used for the first or second notification among the monitor lamp 51, sound from the sound generating unit 52, characters on the display unit 53, an image on the display unit 53, and data transmission by the communication unit 54.

[0055] The above-described modifications can be applied as appropriate to the lighting devices according to the following embodiments. Note that the lighting devices according to the following embodiments have many points in common with embodiment 1, so the following description will focus on the differences from embodiment 1.

[0056] Embodiment 2 10 is a flowchart showing the operation of the lighting device 1 according to embodiment 2. In this embodiment, the condition for performing the second notification is different from that in embodiment 1. The other configurations are the same as those in embodiment 1.

[0057] When an abnormality in the storage battery 3 is detected during inspection, the control device of this embodiment issues a first notification to notify the abnormality in the storage battery 3, and issues a second notification if a predetermined specified time has elapsed since the start of the first notification without the abnormality in the storage battery 3 being resolved. The means used for the first and second notifications can be the same as those in the first embodiment.

[0058] In the storage unit 46 of this embodiment, a notification change time, which is a specified time, can be set in addition to the contents stored in the storage unit 46 of embodiment 1. The notification change time is an arbitrary time, such as one month or three months.

[0059] The operation of the notification unit 5 will be described in detail using Figure 10. The operation up to step 102 is the same as that of the modified example of embodiment 1. In step 102, if the battery voltage of the storage battery 3 is equal to or higher than the discharge reference voltage, it is determined that there is no abnormality. If the battery voltage of the storage battery 3 is lower than the discharge reference voltage, it is determined that there is an abnormality. If there is an abnormality, the control unit 47 causes the notification unit 5 to issue a first notification and causes the timing unit 48 to start counting time (step 203). When the time counted by the timing unit 48 reaches the notification change time stored in the memory unit 46 (step 204), the control unit 47 switches the notification of the notification unit 5 from the first notification to the second notification (step 205).

[0060] According to this embodiment, if the abnormality in the storage battery 3 is not resolved after the first notification is initiated, the control device issues a second notification by a means different from the first notification. This makes it easier for the user to notice the abnormality in the storage battery 3, even if the user does not notice the first notification, by switching the notification means.

[0061] In this embodiment, the first and second notifications are switched. In addition, a third notification unit, a fourth notification unit, etc., using different means than the first and second notifications may be provided. If the storage battery 3 is not replaced despite a notification indicating an abnormality in the storage battery 3, the notification means may be changed sequentially depending on the passage of a specified time, etc. Furthermore, the light beam, sound, font of the text, etc. used to notify the battery may become larger each time the notification means is switched from the first notification to the second notification, and the third notification. This makes the later notification more noticeable. Furthermore, the light beam, sound, font of the text displayed may change more significantly when switching from the second notification to the third notification than when switching from the first notification to the second notification. Furthermore, the notification means is not limited to switching from the first notification to the second notification, and the second notification may be superimposed on the first notification.

[0062] Embodiment 3 11 is a block diagram showing the configuration of a lighting device 1 according to embodiment 3. This embodiment differs from embodiment 2 in that the lighting device 1 has a human presence detection function such as a human presence sensor 8, and in the conditions for issuing a second alert. The other configurations are the same as those of embodiment 2. If an abnormality in the storage battery 3 is detected during inspection, the control device issues a first alert, and if a human is detected by the human presence sensor 8 after the first alert has started and the abnormality in the storage battery 3 has not been resolved, the control device issues a second alert.

[0063] The human presence sensor 8 is, for example, an infrared sensor, a radio wave sensor, an image sensor, or the like. The human presence sensor 8 may be any device that can detect a person. The human presence sensor 8 may also be provided outside the lighting device 1. That is, information on the presence or absence of a person may be obtained from devices surrounding the lighting device 1. For example, information on a person's entry or presence from an entry management system may be transmitted to the lighting device 1. In this way, a lighting control system may be configured with the lighting device 1 and the human presence sensor 8.

[0064] 12 is a flowchart showing the operation of the lighting device 1 according to the third embodiment. The operation is the same as that of the first embodiment up to step 102. In step 102, if the battery voltage of the storage battery 3 is equal to or higher than the discharge reference voltage, it is determined that there is no abnormality. If the battery voltage of the storage battery 3 is lower than the discharge reference voltage, it is determined that there is an abnormality. If there is an abnormality, the control unit 47 causes the notification unit 5 to issue a first notification (step 303).

[0065] When the human sensor 8 detects a person while the first notification is being made (step 304), the timer 48 starts counting time. When the time counted by the timer 48 reaches a specified time stored in the memory 46 (step 305), the control unit 47 switches the notification of the notification unit 5 from the first notification to the second notification (step 306).

[0066] As described above, in this embodiment, when the motion sensor 8 detects a person, the means for notifying the inspection result is switched in conjunction with the detection result. In conventional lighting devices 1, notifications were issued regardless of whether a person was present or not, so the notifications were difficult to notice. In this embodiment, the second notification is issued when a user is present, that is, when the user can check the notification unit 5, making it easier for the user to recognize the inspection result.

[0067] The technical features described in each embodiment may be combined as appropriate. For example, the control of this embodiment may be combined with the control of embodiment 2.
