[0010] Hereinafter, lighting devices and the like according to embodiments will be described with reference to the drawings. In the following drawings, components with the same reference numerals are identical or equivalent, and this applies throughout the following embodiments. The size relationships between components in the drawings may differ from those in reality. The configurations of the components shown in the entire specification are described using an emergency lighting device regulated by the Building Standards Act as an example, but these are merely examples. They may also be emergency lights regulated by the Fire Service Act or lighting devices not regulated by the Building Standards Act or the Fire Service Act. The configurations are not limited to those described in the specification. In particular, the combinations of components are not limited to those in each embodiment, and components described in other embodiments may be applied to other embodiments.

[0011] Embodiment 1 Fig. 1 is a diagram showing the appearance of the lighting device 1 according to the embodiment 1. Fig. 2 is an exploded perspective view of the lighting device 1 according to the embodiment 1.

[0012] 1 and 2, the lighting device 1 according to the first embodiment includes a main body 2, a frame 3, a light source unit 4, a storage battery unit 5, and a control unit 6. The lighting device 1 will be described as an emergency lighting fixture that turns on in an emergency when power is not supplied to the lighting device 1 from a commercial power source provided outside the lighting device 1, such as in the event of a power outage or a break in the power line.

[0013] The main body 2 has a cylindrical shape with an opening formed on one side. The main body 2 has a ceiling mounting spring 21. The main body 2 houses the light source unit 4, the storage battery unit 5, and the control unit 6.

[0014] The ceiling mounting spring 21 is a spring made of a curved metal sheet. The ceiling mounting spring 21 is a mounting member for mounting the lighting device 1 to a mounting portion, which is a structure to which the lighting device 1 is attached, such as a ceiling or a wall.

[0015] The frame 3 is disk-shaped and is attached to the main body 2 so as to close an opening formed in the main body 2. The frame 3 is used to cover a part of the light source unit 4 housed in the main body 2 and a control Unit 6 A hole is formed to expose a part of the surface.

[0016] 3 is a diagram showing the configuration of a light source unit 4 (described later) of the lighting device 1 according to embodiment 1. As shown in FIGS. 2 and 3, the light source unit 4 has a mounting substrate 41, a light source section 42, a lens 43, a dummy load 44, and a heat dissipation section 45. The light source unit 4 is housed in the main body 2 and is detachable from the control unit 6.

[0017] The mounting board 41 has a light source unit 42 and a dummy load 44 mounted on one side.

[0018] The light source unit 42 is an LED (Light Emitting Diode) that emits light when supplied with power. Although the light source unit 42 will be described as being an LED, the light source unit 42 is not limited to this and may be any light-emitting element that emits light when supplied with power, such as an organic EL or laser diode.

[0019] The lens 43 is attached to the mounting substrate 41 so as to cover the light source unit 42, and is exposed to the outside of the main body 2 through a hole formed in the frame 3. The lens 43 focuses or diffuses the light emitted by the light source unit 42.

[0020] The dummy load 44 is configured with an electric resistance element or the like, and converts the supplied power into heat. The dummy load 44 is mounted on the mounting board 41. The dummy load 44 generates heat when power is supplied. 44The dummy load 44 increases the temperature of the peripheral components. The amount of heat generated by the dummy load 44 is limited by the power supply, the number of dummy loads 44 installed, and the layout of the dummy load 44. The dummy load 44 can prevent the light source unit 42 from turning on when an automatic inspection of the lighting device 1, which will be described later, is performed, causing the user to feel uncomfortable or mistakenly believe that an emergency has occurred. The dummy load 44 is not limited to being mounted on the mounting board 41, and may also be mounted on the control unit 6.

[0021] The heat dissipation unit 45 is a heat sink that is attached to the mounting board 41 so as to be in contact with the side opposite to the surface on which the light source unit 42 is mounted, and that dissipates heat generated when the light source unit 42 emits light. Alternatively, the heat dissipation unit 45 is a heat sink that dissipates heat generated when power is supplied to the dummy load 44. The heat dissipation capacity of the heat dissipation unit 45 has a capacity that corresponds to the amount of heat generated by the light source unit 42 or the amount of heat generated by the dummy load 44.

[0022] 4 is a block diagram showing an outline of the configuration of the lighting device 1 according to the first embodiment. As shown in FIGS. 2 and 4, the storage battery unit 5 has a storage battery 51 and a storage unit 52. The storage battery unit 5 is housed in the main body 2 and is detachable from the control unit 6.

[0023] The storage battery 51 is a nickel-metal hydride storage battery (hereinafter referred to as a Ni-MH storage battery). The storage battery 51 is charged by power supplied from a commercial power source. The storage battery 51 is charged by rapid charging when the remaining battery charge is low, and is trickle charged by being supplied with minute amounts of power when the remaining battery charge is high. The storage battery 51 also supplies power to the light source unit 42 when the supply of power from the commercial power source is stopped. Here, the storage battery 51 has been described as a Ni-MH storage battery, but is not limited to this and may be a secondary battery such as a nickel-cadmium storage battery (which may also be referred to as a Ni-Cd storage battery) or a lithium-ion battery (which may also be referred to as a Li-Ion battery).

[0024] The storage unit 52 stores storage battery information indicating the state of the storage battery 51. The storage unit 52 is a storage medium such as an IC (Integrated Circuit) chip or an RFID (Radio Frequency Identifier) ​​tag, and is connected to the control unit 51 by either a contact or non-contact method. 6 Alternatively, the storage battery information can be written or read from an external terminal. When the storage unit 52 is electrically connected to the control device 63 (described later) by a contact method, the storage battery unit 5 52 A socket, connector or housing is provided to be connected to the

[0025] The storage battery information is information for determining whether or not the storage battery 51 can be continuously used. Department Reference numeral 42 denotes the possible lighting duration, which is the time from when lighting is started by the power supplied from the storage battery 51 to when lighting is stopped.

[0026] 2 and 4, the control unit 6 has a lighting circuit 61, a charging circuit 62, a control device 63, an alarm unit 64, a check switch 65, and a light receiving unit 66. The control unit 6 is housed in the main body 2.

[0027] The lighting circuit 61 controls the lighting of the light source unit 42, and when the power supply from the commercial power source is stopped, it supplies power from the storage battery 51 to the light source unit 42, causing the light source unit 42 to emit light.

[0028] The charging circuit 62 receives power supplied from a commercial power source and charges the storage battery 51 .

[0029] The control device 63 is a device that controls the operation of the lighting device 1, such as lighting and inspection of the lighting device 1. 3The hardware of the control device 63 is configured, for example, by a microcomputer or microcontroller having a processing device such as a CPU (Central Processing Unit) and a storage unit made of non-volatile or volatile semiconductor memory such as RAM (Random Access Memory), ROM (Read Only Memory), flash memory, EPROM (Erasable Programmable Read Only Memory), or EEPROM (Electrically Erasable Programmable Read Only Memory). The control device 63 has an inspection processing unit 63A, a timer unit 63B, a determination unit 63C, a writing unit 63D, an acquisition unit 63E, and a status confirmation unit 63F.

[0030] The inspection processing unit 63A is an inspection function that stops the supply of power from the commercial power source to the storage battery 51 using the charging circuit 62, supplies power from the storage battery 51 to the light source unit 42 using the lighting circuit 61 to turn on the light source unit 42, and obtains the available lighting time, which is the time from when the light source unit 42 starts lighting using the power supplied from the storage battery 51 to when the lighting ends. Note that the inspection processing unit 63A is not limited to the available lighting time, and may have any inspection function that obtains storage battery information.

[0031] The timer 63B measures the elapsed time since power was supplied from the commercial power source and the light source. Department Reference numeral 42 denotes a timer function for measuring the time during which lighting can continue from the start of lighting using power supplied from the storage battery 51 until the end of lighting.

[0032] The determination unit 63C has a function of determining whether the storage battery 51 can be used. The determination unit 63C stores a threshold value for determining whether the storage battery 51 can be used. The determination unit 63C compares the storage battery information stored in the memory unit 52 with the threshold value to determine whether the storage battery 51 can be used. Here, the threshold value is a specified value for determining whether the storage battery 51 can be used in the storage battery information item.

[0033] A case will be described where the storage battery information is the possible lighting duration checked by the inspection processing unit 63A. When the storage battery information is the possible lighting duration, the threshold is a predetermined arbitrary value. For example, the threshold is set to 20 minutes, 30 minutes, or 60 minutes, which are times specified by the Building Standards Act or the Fire Service Act. Furthermore, the determination unit 63C obtains the possible lighting duration from the memory unit 52, and determines that the storage battery 51 is usable if the obtained possible lighting duration is greater than the threshold.

[0034] The writing unit 63D writes the storage battery information obtained by the inspection processing unit 63A when the inspection processing unit 63A inspects the storage battery 51 into the memory unit 52. At this time, the writing unit 63D may write the information while in contact with the memory unit 52, or may write the information by transmitting it in a contactless manner.

[0035] The acquisition unit 63E acquires the storage battery information from the storage unit 52 and sends it to the determination unit 63C. At this time, the acquisition unit 63E may acquire the storage battery information while in contact with the storage unit 52, or may receive and acquire the storage battery information in a contactless manner.

[0036] The status checking unit 63F has a function of checking the usability of the storage battery 51 housed in the main body 2. The status checking unit 63F causes the acquisition unit 63E to acquire storage battery information from the memory unit 52, causes the determination unit 63C to compare the storage battery information with a threshold value to determine whether the storage battery 51 is usable, and causes the notification unit 64, which will be described later, to make a notification corresponding to the determination of whether the storage battery 51 is usable.

[0037] The notification unit 64 is one or more monitor LEDs, and notifies the user of the inspection result and the determination of usability of the storage battery 51 depending on the lighting state of the monitor LEDs. The notification unit 64 notifies the result of the determination of usability of the storage battery 51 obtained by the status checking unit 63F using the storage battery information acquired by the acquisition unit 63E from the storage unit 52. Note that although the notification unit 64 has been described as a monitor LED, it is not limited to this and may be capable of displaying using a segment display or a liquid crystal display, and the storage battery information or the result of the determination of usability of the storage battery 51 may be displayed as data. outsideIt may also be something that transmits to external equipment.

[0038] The inspection switch 65 is one or more switches that inspect the storage battery 51 or 51 When the inspection switch 65 is pressed, it operates in accordance with various inspection modes, which will be described later.

[0039] The light receiving unit 66 receives an operation signal wirelessly sent from a terminal such as a remote controller (not shown). The light receiving unit 66 may receive a signal that causes the inspection processing unit 63A to inspect the storage battery 51. 3 Alternatively, the signal for causing the state confirmation unit 63F to perform the above operation may be received.

[0040] 5 is a diagram illustrating modes that can be executed in the lighting device 1 according to embodiment 1. Next, four modes of the lighting device 1 according to embodiment 1, namely, (a) normal lighting mode, (b) emergency lighting mode, (c) manual inspection mode, and (d) automatic inspection mode, will be described.

[0041] The normal lighting mode (a) is a mode in which power is supplied from a commercial power source and is a normal state. The charging circuit 62 supplies power from the commercial power source to the storage battery 51 to charge the storage battery 51. At this time, the lighting circuit 61 may supply power from the commercial power source to the light source unit 42 to cause the light source unit 42 to emit light.

[0042] The emergency lighting mode (b) is a mode used in an emergency situation in which the supply of power from the commercial power source is stopped and power is not supplied to the lighting device 1 from a commercial power source provided external to the lighting device 1 due to a power outage, a break in the power supply, or the like. In the emergency lighting mode, when the supply of power from the commercial power source is stopped, charging of the storage battery 51 by the charging circuit 62 is stopped and the lighting circuit 61 supplies power from the storage battery 51 to the light source unit 42 to light the light source unit 42. At this time, the storage battery 51 discharges as the light source unit 42 acts as a load.

[0043] The manual inspection mode (c) is a mode in which the inspection processing unit 63A inspects the storage battery 51 while the inspection switch 65 is being operated. Here, the manual inspection mode is not limited to the inspection switch 65, and the inspection processing unit 63A may be caused to perform the inspection by the light receiving unit 66 receiving a signal to start the inspection.

[0044] The automatic inspection mode (d) is a mode in which an inspection is automatically performed using the inspection interval time, which is the time measured after the storage battery 51 receives power from the commercial power source, as the elapsed inspection start condition. The inspection interval time is a predetermined time. When the time calculated by the timer unit 63B has elapsed the inspection interval time, the lighting device 1 starts the inspection process even if the inspection switch 65 has not been pressed. Reason The inspection interval is set to, for example, six months or one year. The inspection interval is not limited to six months or one year, and may be any time.

[0045] In the manual inspection mode, inspections are performed by an administrator to confirm whether the storage battery 51 is usable. However, because the frequency of inspections depends on the administrator, there is a concern that if the inspection interval is long, the storage battery 51 may not be replaced at the appropriate time. The automatic inspection mode can alleviate such concerns, and the storage battery 51 is inspected automatically at regular intervals.

[0046] In the lighting device 1, the duration for which the storage battery 51 can continuously light the light source unit 42 varies depending on the charge level of the storage battery 51 and the deterioration state of the storage battery 51. The storage battery 51 is trickle charged and is controlled so that the power of the storage battery 51 is always fully charged. However, as the storage battery 51 deteriorates, the duration for which the storage battery 51 can continuously light tends to shorten over time, even when it is fully charged. For this reason, the lighting device 1 periodically checks whether the light source unit 42 can light for a specified lighting period or longer to check the deterioration state of the storage battery 51. If deterioration of the storage battery 51 is detected, the manager of the lighting device 1 replaces the storage battery 51 to maintain the light source unit 42 in a state where it can light for a specified lighting period or longer.

[0047] Fig. 6 is a flowchart relating to the inspection operation of the lighting device 1 according to the first embodiment. Next, the inspection function of the lighting device 1 will be described. It is assumed that the flowchart of Fig. 6 starts when a user operates the inspection switch 65 or the light receiving unit 66 to start the operation of the inspection processing unit 63A. Examples of operations to start the operation of the inspection processing unit 63A include pressing a switch of the inspection switch 65 that operates the inspection processing unit 63A or causing the light receiving unit 66 to receive a signal that operates the inspection processing unit 63A.

[0048] In step S101, the inspection processing unit 63A causes the charging circuit 62 to stop supplying power from the commercial power source to the storage battery 51.

[0049] After the process of step S101 is completed, the process proceeds to step S102. In step S102, the inspection processing unit 63A causes the lighting circuit 61 to supply power from the storage battery 51 to the light source unit 42, thereby lighting up the light source unit 42. The storage battery 51 discharges with the light source unit 42 acting as a load. At this time, the timing unit 63B starts timing at the same timing as the light source unit 42 starts lighting up.

[0050] After the process of step S102 ends, the process proceeds to step S103. In step S103, the inspection processing unit 63A acquires the voltage of the storage battery 51.

[0051] After the processing of step S103 is completed, the process proceeds to step S104. In step S104, the inspection processing unit 63A determines whether the voltage of the storage battery 51 is below the discharge reference voltage, which is the voltage at which the light source unit 42 can be turned on. If it is determined in step S104 that the voltage of the storage battery 51 is below the discharge reference voltage (step S104, YES), the process proceeds to step S105. In this case, it is determined that the light source unit 42 cannot be turned on. If it is determined in step S104 that the voltage of the storage battery 51 is equal to or higher than the discharge reference voltage (step S104, NO), the process of step S103 is performed again. In this case, it is determined that the light source unit 42 can be continuously turned on.

[0052] If it is determined in step S104 that the voltage value of the storage battery 51 is a value that prevents the light source unit 42 from being turned on (S104, YES), the process proceeds to step S105. In step S105, the inspection processing unit 63A stops the supply of power from the storage battery 51 to the light source unit 42 by the lighting circuit 61, and ends the lighting of the light source unit 42. At this time, the timing unit 63B ends the timing that started after the light source unit 42 was turned on, and obtains the possible lighting duration, which is storage battery information.

[0053] After the process of step S105 ends, the process proceeds to step S106. In step S106, the inspection processing unit 63A causes the charging circuit 62 to supply power from the commercial power supply to the storage battery 51, and charging of the storage battery 51 begins.

[0054] After the process of step S106 ends, the process proceeds to step S107. In step S107, the inspection processing unit 63A causes the writing unit 63D to write into the storage unit 52 the possible lighting continuation time, which is the storage battery information.

[0055] FIG. 7 is a flowchart illustrating the operation of determining whether or not the storage battery 51 of the lighting device 1 according to the first embodiment is usable and providing a notification. Next, the determination of whether or not the storage battery 51 is usable and providing a notification using the remaining lighting time, which is the storage battery information stored in the memory unit 52 of the lighting device 1, will be described. It is assumed that the flowchart of FIG. 7 starts when the user operates the inspection switch 65 or the light-receiving unit 66 to start the operation of the status confirmation unit 63F. Examples of operations that start the operation of the status confirmation unit 63F include pressing a switch of the inspection switch 65 that activates the status confirmation unit 63F or causing the light-receiving unit 66 to receive a signal that activates the status confirmation unit 63F. The flowchart of FIG. 7 does not necessarily start when the inspection switch 65 or the light-receiving unit 66 is operated, and may start after the inspection flowchart of FIG. 6 has finished.

[0056] In step S201, the state confirmation unit 63F causes the acquisition unit 63E to acquire the remaining lighting time, which is the storage battery information, from the storage unit 52, and transmit it to the determination unit 63C.

[0057] After the process of step S201 is completed, the process proceeds to step S202. In step S202, the determination unit 63C determines whether the possible lighting duration, which is the battery information, is equal to or greater than a threshold value. If the determination unit 63C determines in step S202 that the possible lighting duration, which is the battery information, is equal to or greater than the threshold value (S202, YES), the process proceeds to step S203. At this time, the storage battery 51 is determined to be usable. If the determination unit 63C determines in step S202 that the possible lighting duration, which is the battery information, is a value below the threshold value (S203, NO), the process proceeds to step S204. At this time, the storage battery 51 is determined to be unusable.

[0058] If it is determined in step S202 that the battery information indicates that the possible lighting duration is longer than the threshold (YES in step S202), the process proceeds to step S203. In step S203, the notification unit 64 issues a notification indicating the determination result that the battery 51 is usable.

[0059] If it is determined in step S202 that the battery information indicates that the allowable lighting time is shorter than the threshold (S202, NO), the process proceeds to step S204. In step S204, the notification unit 64 issues a notification indicating the determination result that the battery 51 is unusable.

[0060] Next, the effects of the lighting device 1 according to the first embodiment will be described.

[0061] The lighting device 1 of the first embodiment includes a main body 2 attached to an attachment portion, a storage battery unit 5 that has a storage battery 51 and a storage unit 52 that stores storage battery information indicating the state of the storage battery 51 and that can be housed in the main body 2, and a control device 63 that acquires the storage battery information stored in the storage unit 52. Therefore, when the storage battery unit 5 is replaced, the lighting device 1 can acquire the storage battery information from the storage unit 52 of the storage battery unit 5 without having to perform a new inspection.

[0062] Furthermore, the lighting device 1 of the first embodiment further includes a determination unit 63C that determines whether the storage battery 51 is usable by comparing the storage battery information acquired from the storage unit 52 with a threshold value for determining whether the storage battery 51 is usable, and a notification unit 64 that notifies the determination result of the determination unit 63C. Therefore, when the storage battery unit 5 is replaced, the lighting device 1 can notify the determination result of whether the storage battery 51 is usable from the notification unit 64 without having to perform a new inspection.

[0063] Furthermore, the control device 63 of the lighting device 1 of the first embodiment has a writing unit 63D that inspects the storage battery 51 and writes the inspection results into the storage unit 52 as storage battery information of the storage battery 51. Therefore, in the lighting device 1, the storage battery information, which is information for determining whether the storage battery 51 can be continuously used, is written into the storage unit 52 attached to the storage battery unit 5, so that the storage battery information of the storage battery 51 can be confirmed even if the storage battery unit 5 is not attached to the main body 2.

[0064] In the lighting device 1 of the first embodiment, the storage unit 52 of the storage battery unit 5 is a storage medium such as an IC chip or an RFID tag, and the control device 63 The lighting device 1 acquires the storage battery information from the storage unit 52 in a non-contact manner. 3 The memory unit 52 and the control device 6 can be connected without performing any wiring work between them. 3 Battery information can be communicated between Controlled by This makes it easy to attach and detach the storage battery unit 5 to the control unit 6.

[0065] Next, a first modification of the first embodiment will be described.

[0066] Inspection of the lighting device 1 in this embodiment 1 is performed by the inspection processing unit 63A, and as explained above, the supply of power from the commercial power source to the storage battery 51 is stopped and power is supplied from the storage battery 51 to the light source unit 42 to turn on the light source unit 42. However, the target to which power is supplied from the storage battery 51 is not limited to the light source unit 42, and it may also be a dummy load 44 provided in the light source unit 4.

[0067] Since the dummy load 44 generates heat when power is supplied, it prevents the light source unit 42 from emitting light when the power supply from the commercial power source is stopped, which can lead the user to mistakenly believe that there is a power outage or an abnormality, during an inspection in the automatic inspection mode of the emergency lighting device, in which the light source unit 42 emits light.

[0068] The dummy load 44 can receive power from the storage battery 51 at a level equal to or greater than the power consumed in the emergency lighting mode. In this case, the storage battery 51 consumes power faster than during inspection when the light source unit 42 is used as a load, thereby shortening the inspection time. The power supplied to the dummy load 44 may be set arbitrarily, and the relationship between the supplied power and the inspection time may be set, for example, such that when the supplied power is twice the power supplied to the light source unit 42, the inspection time is half the specified lighting time of the light source unit 42.

[0069] Next, a second modification of the first embodiment will be described.

[0070] Although the threshold value of the lighting device 1 of the first embodiment has been described as being stored in the determination unit 63C of the control device 63, the storage target is not limited to the determination unit 63C, and the threshold value may be stored in the storage unit 52. In this case, the acquisition unit 63E acquires the storage battery information and the threshold value from the storage unit 52, and the determination unit 63C compares the acquired storage battery information with the threshold value to determine the storage battery information. 51 Determine whether is available.

[0071] In the lighting device 1 of variant example 2, the storage battery information and thresholds are stored in the memory unit 52 of the storage battery unit 5. Therefore, even if the thresholds of the storage battery unit 5 to be replaced are different, a threshold suitable for the storage battery 51 can be set, and the judgment unit 63C can judge whether the storage battery 51 can be used.

[0072] Next, a third modification of the first embodiment will be described.

[0073] Although the storage battery information of the lighting device 1 in the present embodiment 1 has been described as the possible continuous lighting time, it is not limited to the possible continuous lighting time, and may be information indicating the state of the storage battery 51 obtained by inspecting the storage battery 51 by the inspection processing unit 63A, such as the voltage transition when the storage battery 51 is discharged, the number of inspections of the storage battery 51, the voltage when the storage battery 51 is charged, or the charging time of the storage battery 51. In this case, the threshold value stored in the determination unit 63C is arbitrarily set to a value corresponding to the storage battery information.

[0074] Furthermore, the battery information of the lighting device 1 of this embodiment 1 is not limited to information obtained by inspecting the storage battery 51 by the inspection processing unit 63A, but may also be information obtained when the storage battery 51 is attached to the main body 2, regardless of the inspection being performed, such as the elapsed time since the storage battery 51 was charged by a commercial power source, the temperature history around the storage battery 51, or the number of times that power has been supplied from the storage battery 51 to the light source unit 42 to turn on the light source unit 42.

[0075] Furthermore, the battery information of the lighting device 1 of the present embodiment 1 is not limited to information obtained when the storage battery 51 is attached to the main body 2, but may be information indicating the specifications of the storage battery 51, such as the model name or type information of the storage battery 51. In this case, the battery information is stored in the storage unit 52 before the storage battery 51 is attached to the main body 2.

[0076] In the lighting device 1 of variant example 3, the battery information is not only the possible lighting duration, but also information obtained by inspecting the battery 51, information when the battery 51 is attached to the main body 2, or information stored in the memory unit 52 before the battery 51 is attached to the main body 2, so that the determination unit C can have a higher degree of freedom in selecting the items to determine whether the battery 51 can be used.

[0077] Embodiment 2 The illumination device 1 according to the second embodiment will be described, focusing on the differences in configuration and operation from the light source device 100 according to the first embodiment.

[0078] Fig. 8 is a block diagram showing an outline of the configuration of the lighting device 1 according to embodiment 2. As shown in Fig. 8, the light source unit 4 has a light source unit storage unit 46. The light source unit 4 is housed in the main body 2 and is detachable from the control unit 6.

[0079] The light source unit storage unit 46 stores light source unit information indicating the state of the light source unit 42. The light source unit storage unit 46 is a storage medium such as an IC (Integrated Circuit) chip or an RFID (Radio Frequency Identifier) ​​tag, and is stored in the control unit 42 by either a contact or non-contact method. 6 Alternatively, the light source unit information is written or read from an external terminal. 1 It may be mounted on the heat sink 45 or may be attached to the heat sink 45.

[0080] The light source unit information is information for determining whether the light source unit 42 can be continuously used. For example, the light source unit information is a possible continuous lighting time, which is the time from when the light source unit 42 starts to light up using power supplied from the storage battery 51 until when the light source unit 42 stops lighting. Note that the light source unit information is not limited to the possible continuous lighting time, and may also be the model name of the light source unit 42, model information of the light source unit 42, the lighting time of the light source unit 42, the luminous flux of the light source unit 42, or temperature history. The light source unit information may be any item for determining the specifications of the light source unit 42 or whether the light source unit 42 can be used, and is not limited to the items listed in this paragraph.

[0081] The control device 63 has an inspection processing unit 631A, a timer unit 63B, a determination unit 631C, a writing unit 631D, an acquisition unit 631E, and a status confirmation unit 631F.

[0082] The inspection processing unit 631A stops the supply of power from the commercial power source to the storage battery 51 by the charging circuit 62, and supplies power from the storage battery 51 to the light source unit 42 by the lighting circuit 61 to light the light source unit 42, and Department The inspection processing unit 631A is an inspection function that obtains the possible lighting duration, which is the time from when the light source unit 42 starts to light up using the power supplied from the storage battery 51 until when the light ends. Note that the inspection processing unit 631A is not limited to the possible lighting duration, and any inspection function that obtains light source unit information is sufficient. Here, the lighting duration of the light source unit 42 using the storage battery 51 is stipulated in the Building Standards Act and the Fire Service Act, and is 30 or 60 minutes for emergency lighting fixtures and 20 or 60 minutes for emergency lights.

[0083] The determination unit 631C has a function for determining whether the light source unit 42 can be used. The determination unit 631C stores a light source unit threshold value for determining whether the light source unit 42 can be used. The determination unit 631C determines whether the light source unit 42 can be used by comparing the light source unit information, which indicates the possible lighting duration, with the light source unit threshold value. Here, the determination unit 631C may determine whether the light source unit 42 is unused or has been used. Here, the light source unit threshold value is a specified value for determining whether the light source unit 42 can be used in the item of light source unit information.

[0084] A case will be described where the light source unit information is the possible continuous lighting time confirmed by the inspection processing unit 631A. When the light source unit information is the possible continuous lighting time, the threshold is a predetermined arbitrary value. For example, the threshold is set to 20 minutes, 30 minutes, or 60 minutes, which are times specified by the Building Standards Act or the Fire Service Act. Furthermore, the determination unit 63C acquires the possible continuous lighting time from the memory unit 52, and determines that the storage battery 51 is usable if the acquired possible continuous lighting time is greater than the threshold.

[0085] The writing unit 631D writes the possible lighting duration, which is light source unit information obtained by the inspection processing unit 631A when inspecting the light source unit 42, into the light source unit storage unit. 46 At this time, the writing unit 631D may write the information in a state of contact with the light source unit storage unit 46, or may write the information by transmitting it in a contactless manner.

[0086] The acquisition unit 631E acquires the light source unit information, ie, the lighting duration, from the light source unit storage unit 46, and sends it to the determination unit 631C. At this time, the acquisition unit 631E may acquire the light source unit information while in contact with the light source unit storage unit 46, or may receive and acquire the light source unit information in a contactless manner.

[0087] The status checking unit 631F has a function of checking the usability of the light source unit 42 attached to the main body 2. The status checking unit 631F causes the acquisition unit 631E to acquire the light source unit information, which is the possible lighting duration, from the light source unit storage unit 46, causes the determination unit 631C to compare the light source unit information, which is the possible lighting duration, with a light source unit threshold value and determine whether the light source unit 42 is usable, and causes the notification unit 641, which will be described later, to give a notification corresponding to the determination of whether the light source unit 42 is usable.

[0088] The notification unit 641 notifies the user of the inspection result and the determination of usability of the light source unit 42 based on the lighting state of the monitor LED. The notification unit 641 notifies the user of the determination result of usability of the light source unit 42 obtained by the status checking unit 631F using the light source unit information acquired by the acquisition unit 631E from the light source unit storage unit 46.

[0089] The inspection switch 651 is operated when inspecting the light source unit 42 .

[0090] Next, the effects of the lighting device 1 according to the second embodiment will be described.

[0091] The lighting device 1 of the second embodiment is equipped with a main body 2 that is attached to an attachment portion, a light source unit 4 that has a light source unit 42 and a light source unit storage unit 46 that stores light source unit information indicating the state of the light source unit 42, and is housed in the main body 2 and is detachable from the control unit 6, and a control device 63 that acquires the light source unit information stored in the light source unit storage unit 46. Therefore, when the light source unit 4 is replaced, the lighting device 1 can acquire the light source unit information from the light source unit storage unit 46 of the light source unit 4 without having to perform a new inspection.

[0092] Furthermore, the lighting device 1 of the second embodiment further includes a determination unit 631C that determines whether the light source unit 42 is usable by comparing the light source unit information acquired from the light source unit storage unit 46 with a light source unit threshold value for determining whether the light source unit 42 is usable, and a notification unit 641 that notifies the determination result of the determination unit 631C. Therefore, when the light source unit 4 is replaced, the lighting device 1 can notify the determination result of whether the light source unit 42 is usable from the notification unit 641 without having to perform a new inspection.

[0093] Furthermore, the control device 63 of the lighting device 1 of the second embodiment has an inspection processing unit 63A that inspects the light source unit 42 and writes information indicating whether the light source unit 42 can be used continuously based on the inspection result as light source unit information in the light source unit storage unit 46. Therefore, in the lighting device 1, the information indicating whether the light source unit 42 can be used continuously is written in the light source unit storage unit 46 attached to the light source unit 4, so that the light source unit information of the light source unit 42 can be confirmed even if the light source unit 4 is not attached to the main body 2.

[0094] Here, the lighting device 1 of the second embodiment may be configured such that the light source unit storage unit 46 is attached to the light source unit 4, and the storage unit 52 is attached to the storage battery unit 5. In this case, the control device 63 writes and reads information to and from the light source unit storage unit 46 and the storage unit 52, respectively, and determines whether or not each can be used.
