The disaster prevention lighting equipment 1 is a guide light, an emergency lighting equipment, or the like. Guide lights and emergency lighting equipment must be inspected in accordance with laws and regulations. The timing for inspecting guide lights is stipulated by the Fire Service Act, and the timing for inspecting emergency lighting equipment is stipulated by the Building Standards Act.

Furthermore, if a predetermined number of years have not passed since the manufacturing year of the storage battery installed in the guide light, the above-mentioned inspection of the guide light may not be necessary in consideration of the lifespan of the storage battery. In this case, if a predetermined number of years have passed since the year of manufacture of the storage battery installed in the guide light, it is necessary to carry out the above-mentioned inspection on the guide light, taking into consideration the lifespan of the storage battery. For example, if the storage battery is a nickel-cadmium battery, an inspection must be performed if more than three years have passed since the battery was manufactured. Furthermore, if the storage battery is a nickel-metal hydride battery, an inspection must be carried out if more than five years have passed since the year of manufacture of the storage battery.

However, the reality is that it is difficult to say that inspections are carried out at appropriate times (for example, at times specified by laws and regulations). Therefore, the disaster prevention lighting equipment 1 according to the present embodiment has the following notification function in order to perform inspection at an appropriate time taking into consideration the lifespan of the storage battery.

First, as a premise, in the disaster prevention lighting device 1 according to the present embodiment, if the usage period of the battery 3 does not exceed a predetermined time, it is not necessary to perform an inspection on the disaster prevention lighting device 1. Therefore, the control circuit 42 controls the notification circuit 43 to issue a notification after the usage period of the battery 3 reaches a predetermined time.

The control circuit 42 is configured to have the functions of a power supply timer 421 and a check timer 422. When the control circuit 42 has a real-time clock (RTC), the power supply timer 421 and the inspection timer 422 measure the elapsed time by periodically reading the value of the real-time clock and integrating the count value. Performs timekeeping operation. Alternatively, the power supply timer 421 and the inspection timer 422 may be counters that measure time by incrementing a count value at a constant period (for example, a period of a clock frequency).

The power supply timer 421 measures the usage period Ta of the battery 3. In this embodiment, the period of use Ta is the elapsed time from the time when the charging circuit 40 starts charging the battery 3 . The starting point of the usage period Ta is, for example, the time when charging of the new battery 3 is started. However, the starting point of the usage period Ta may be the time when the new battery 3 is fully charged by the charging circuit 40. Then, when the power supply timer 421 starts counting the use period Ta, the measured value of the use period Ta increases from zero as time passes. Further, the power supply timer 421 is reset when the battery 3 is replaced with a new battery 3, and the time value becomes zero. In this embodiment, after replacing the battery 3, a person simultaneously presses the push button switches 49A and 49B. The control circuit 42 resets the power timer 421 when the pushbutton switches 49A and 49B are pressed simultaneously. After the power supply timer 421 is reset, the clock value increases again from zero.

Alternatively, when the control circuit 42 operates using only emergency power, the control circuit 42 may detect whether the battery 3 is to be replaced based on whether or not the emergency power is supplied. For example, immediately before the voltage of the emergency power transmission path falls below the operating voltage of the control circuit 42 and the operation of the control circuit 42 stops, the control circuit 42 obtains time information immediately before the stop based on the value of the real-time clock. Remember it. Immediately after the voltage of the emergency power transmission path exceeds the operating voltage of the control circuit 42 and the operation of the control circuit 42 is restarted, the control circuit 42 provides time information immediately after restart based on the value of the real-time clock. get. The control circuit 42 determines the stop time during which the operation was stopped from the difference between the time information immediately before the stop and the time information immediately after the restart, and if the stop time is longer than a certain time, detects that the battery 3 needs to be replaced. and resets the power timer 421.

The inspection timer 422 measures the period after the completion of the inspection for discharging the battery 3 as an uninspected period Tb. More specifically, after the inspection is performed, the inspection timer 422 measures the uninspected period Tb in order to determine when to inspect the same battery 3 again. When the inspection timer 422 starts counting the uninspected period Tb, the measured value of the uninspected period Tb increases from zero as time passes. Further, the inspection timer 422 is reset when an inspection is performed, and the time value becomes zero. Similarly, the inspection timer 422 is reset when the battery 3 is replaced, and the clock value becomes zero. In this embodiment, a person simultaneously presses the push button switches 49A and 49C after inspection and after replacing the battery 3. The control circuit 42 resets the inspection timer 422 when the pushbutton switches 49A and 49C are pressed simultaneously. Alternatively, the control circuit 42 may reset the power supply timer 421 when the control circuit 42 executes the inspection. After reset, the clock value increases again from zero.

The control circuit 42 has the functions of a power supply timer 421 and an inspection timer 422, and also has a notification control circuit 423 that controls the notification of the notification circuit 43.

The notification control circuit 423 uses the time value of the power supply timer 421 to perform a first notification control process that causes the notification circuit 43 to perform the first notification. The notification control circuit 423 stores data of the first notification period [Tc] in advance, and performs a comparison process between the usage period Ta and the first notification period [Tc]. Then, when the use period Ta reaches the first notification period [Tc], the notification control circuit 423 controls the notification circuit 43 to perform the first notification.

The first notification in this specification refers to notification performed when the usage period Ta measured by the power supply timer 421 reaches the first notification time [Tc]. The first notification period [Tc] is an inspection period specified by law, and is a period equivalent to, for example, three years or five years.

Further, the notification control circuit 423 uses the measured value of the inspection timer 422 to perform a second notification control process that causes the notification circuit 43 to perform a second notification. The notification control circuit 423 stores data of the second notification period [Td] in advance, and performs a comparison process between the uninspected period Tb and the second notification period [Td]. Then, when the uninspected period Tb reaches the second notification period [Td], the notification control circuit 423 controls the notification circuit 43 to perform the second notification.

The second notification in this specification refers to a notification performed when the non-inspection period Tb counted by the inspection timer 422 reaches the second notification period [Td]. The second notification period [Td] is an inspection period specified by law, and is, for example, an arbitrary period of 6 months or less or 12 months or less.

(2.6) Notification Circuit The notification circuit 43 has a first function of making a first notification, and a second function of making a second notification. The notification circuit 43 performs first notification and second notification under the control of the notification control circuit 423 of the control circuit 42 . More specifically, as a first function, the notification circuit 43 performs the first notification using light when the usage period Ta measured by the power supply timer 421 reaches the first notification period [Tc]. Further, the notification circuit 43 performs a second notification using light when the uninspected period Tb counted by the inspection timer 422 reaches the second notification period [Td].

The notification circuit 43 is a notification section having a notification function, and includes, for example, a display element 431 different from the light source 2 and a drive circuit 432 that drives the display element 431 to emit light. The display element 431 is, for example, a light emitting diode that emits green light or a light emitting diode that emits red light. The notification circuit 43 performs the first notification and the second notification using light using the display element 431. For example, the notification circuit 43 may perform the first notification and the second notification by blinking the display element 431, or may perform the first notification and the second notification by lighting the display element 431.

By the way, the power supply timer 421 continues to time the usage period Ta even if the battery 3 is inspected before the usage period Ta reaches the first notification period [Tc]. In other words, before the usage period Ta reaches the first notification period [Tc], the power supply timer 421 continues to time the usage period Ta, regardless of whether or not the battery 3 is inspected.

On the other hand, if the battery 3 is inspected before the non-inspection period Tb reaches the second notification period [Td], the inspection timer 422 resets the time value of the non-inspection period Tb. In other words, if the battery 3 is not inspected before the uninspected period Tb reaches the second notification period [Td], the inspection timer 422 continues to measure the uninspected period Tb, but the battery 3 is not inspected. When this is done, the inspection timer 422 resets the time value of the uninspected period Tb.

(3) Operation of disaster prevention lighting equipment Hereinafter, the operation of the disaster prevention lighting equipment 1 according to the present embodiment will be explained with reference to FIG. 2.

First, in the lighting device 4, when the control circuit 42 starts supplying emergency power, the control circuit 42 assumes that charging of the battery 3 has started and starts timing the usage period Ta by the power supply timer 421 ( time t0). When the power supply timer 421 starts counting the usage period Ta, the measured value of the usage period Ta increases from zero as time passes.

Thereafter, when the use period Ta reaches the first notification period [Tc] (time t1), the notification circuit 43 performs the first notification N1. When the first notification N1 is issued, the inspector performs an inspection E1 of the battery 3 (time t2). When the inspection E1 is completed, the inspection timer 422 starts counting the uninspected period Tb (time t3). The notification circuit 43 performs the second notification N2 when the uninspected period Tb reaches the second notification period [Td] (time t4). When the second notification N2 is issued, the inspector performs the inspection E2 (time t5). When the inspection E2 is completed, the inspection timer 422 is reset, and the inspection timer 422 starts measuring the uninspected period Tb (time t6). If the battery 3 replacement process is not executed, the uninspected period Tb reaches the second notification period [Td] again, and the notification circuit 43 issues the second notification N2. When the second notification N2 is issued, the inspector performs an inspection E2. When the inspection E2 is completed, the inspection timer 422 is reset, and the inspection timer 422 starts counting the uninspected period Tb.

On the other hand, if the replacement process C1 for replacing the battery 3 is executed before the uninspected period Tb reaches the second notification period [Td], the power supply timer 421 and the inspection timer 422 are reset (time t7). When the replacement process C1 is completed, the power supply timer 421 starts counting the usage period Ta (time t8). Thereafter, operations similar to those described above are repeated.

That is, even if the lighting device 4 is not inspected by an inspector, the usage period Ta of the battery 3 is the first notification period [Tc] (for example, 3 years or 5 years as determined by law). After reaching , the first notification N1 is performed. Therefore, the lighting device 4 issues the first notification N1 at an appropriate time taking into consideration the life span of the battery 3 and the like.

Further, the lighting device 4 periodically issues the second notification N2 until the battery 3 is replaced. At this time, the second notification period [Td] is shorter than the first notification period [Tc] from the start of time measurement of the usage period Ta until the first notification N1 is performed. Then, the lighting device 4 issues a second notification N2 if the battery 3 is not replaced after the first inspection. Therefore, the lighting device 4 can prompt for inspection at an appropriate time taking into consideration the life span of the battery 3 and the like. The control circuit 42 acquires the current time from the real-time clock, and according to a predetermined schedule, the control circuit 42 determines the current time according to a predetermined schedule during a time period when notification is possible (for example, a time period when there are people in the building where the disaster prevention lighting equipment 1 is installed). It is preferable to perform a notification operation.

(4) Structure of disaster prevention lighting fixture The structure of the disaster prevention lighting fixture 1 including the lighting device 4 will be described below with reference to FIGS. 3A to 3C.

The disaster prevention lighting system B1 includes a plurality of (four in the illustrated example) disaster prevention lighting fixtures 1. In each disaster prevention lighting fixture 1, the lighting device 4 performs a first notification and a second notification.

(6) Modification Example As a modification example 1 of the present embodiment, the lighting device 4 may include a notification section that provides the first notification and the second notification by sound. The notification section includes, for example, a sound generation section such as a piezoelectric sounder, and a sound drive circuit that drives the sound generation section to generate a notification sound, a notification message, or the like.

The notification unit performs the first notification and the second notification by outputting notification sound from the sound generation unit. The notification sound may be a buzzer sound such as "beep beep" or a voice message such as "Please perform an inspection." When the inspector hears the notification sound, he or she can perform the inspection by operating the wireless transmitter or push button switch 49A. In addition, when performing the first notification and the second notification, the notification unit may output the notification sound continuously or may output the notification sound intermittently.

Further, the notification section of the lighting device 4 may perform the first notification using light and the second notification using sound, or may perform the first notification using sound and may perform the second notification using light. In short, the notification section of the lighting device 4 only needs to have a first function of providing a first notification using at least one of light and sound, and a second function of providing a second notification of at least one of light and sound. .

Alternatively, the lighting device 4 may include a notification section that performs the first notification and the second notification using the identifier. An identifier is, for example, a character such as "It's time for inspection", a symbol such as "〇" or "x", or a pattern, or a combination of characters, symbols, or patterns.

The notification section may include a light source provided inside the main body 10 and emit light from the light source toward a symbol-shaped through hole provided in the main body 10 or the cover 11. That is, it is preferable that the identifier be formed on the cover 11 in the form of a watermark.

Alternatively, the notification section may include a display section such as a liquid crystal display. The display section is provided on the main body 10, for example, and displays characters such as "It's time for inspection" or symbols such as "O" or "x".

Further, the notification section of the lighting device 4 may perform the first notification using light or sound and the second notification using an identifier, or may perform the first notification using an identifier and the second notification using light or sound. Good too. In short, the notification unit of the lighting device 4 has a first function of making a first notification using at least one of light, sound, and an identifier, and a second function of making a second notification using at least one of light, sound, and an identifier. It is enough if you have it.

As a second modification of the present embodiment, the usage period Ta of the battery 3 as an emergency power source is the elapsed time from the time when the battery 3 was manufactured, instead of the elapsed time from the time when charging of the battery 3 was started. Good too. In this case, when the battery 3 is manufactured, a recording medium such as an ID chip or an IC tag storing battery information including the manufacturing date or the elapsed time from the manufacturing date is attached to the battery 3. When the electrical connection with the battery 3 is established, the control circuit 42 reads battery information from the recording medium and sets the initial value of the usage period. Note that the information indicating the time of manufacture of the battery 3 may be the date of manufacture of the battery 3, the date of manufacture of the battery 3, or the year of manufacture of the battery 3.

As a third modification of the present embodiment, the usage period Ta of the battery 3 as an emergency power source is the elapsed time from the time the battery 3 is installed, instead of the elapsed time from the time when charging of the battery 3 is started. Good too. That is, the period of use Ta may be the elapsed time since the battery 3 was installed. In this case, a detection element is provided that detects that the connection terminal connected to the wiring from the battery 3 and the connection terminal connected to the wiring on the lighting circuit 41 side are connected. The time when the detection element detects that the two connection terminals are connected is the start of the usage period.

As a fourth modification of the present embodiment, the usage period Ta of the battery 3 as an emergency power source is based on at least two points: when charging of the battery 3 is started, when the battery 3 is manufactured, and when the battery 3 is installed. It may also be the elapsed time from the timing obtained.

As a fifth modification of the present embodiment, the notification section of the lighting device 4 may perform the first notification and the second notification using light using the light source 2. In this case, the notification control circuit 423 performs notification by changing the lighting state of the light source 2. For example, the notification control circuit 423 periodically changes the light amount of the light source 2, periodically changes the light color of the light source 2, or causes the light source 2 to blink. Note that the notification section may perform the first notification using the light source 2 and may perform the second notification using the display element. Alternatively, the notification section may perform the first notification using the display element and may perform the second notification using the light source 2. In short, the notification unit may perform at least one of the first notification and the second notification using light using the light source 2.

In addition, when performing at least one of the first notification and the second notification, the notification unit first turns on the light source 2 in a dimmed manner (or blinks) at a lower or higher light intensity than the lighting in an emergency, and keeps the light source 2 constant from the start of lighting. After the time has elapsed, the light source 2 may be turned on (or blinked) with the same amount of light as when turned on in an emergency. Alternatively, the notification unit may gradually increase the amount of light from the light source 2 when performing at least one of the first notification and the second notification. Alternatively, when performing at least one of the first notification and the second notification, the notification unit first lights up (or blinks) the display element 431, and after a certain period of time has elapsed from the start of lighting of the display element 431, the light source 2 may be lit (or blinking). Note that the dimming level during dimming lighting is a dimming level of less than 100% or a dimming level of more than 100%.

As a sixth modification of the present embodiment, the notification unit of the lighting device 4 may perform the first notification and the second notification using light using at least one of the plurality of light emitting elements of the light source 2. Light source 2 includes a plurality of light emitting elements. Note that the notification section may perform the first notification using at least one of the plurality of light emitting elements, and may perform the second notification using a display element. Alternatively, the notification section may perform the first notification using a display element, and may perform the second notification using at least one of the plurality of light emitting elements. In short, the notification unit may perform at least one of the first notification and the second notification using light using a plurality of light emitting elements of the light source 2.

As a seventh modification of the present embodiment, the notification section of the lighting device 4 may use the monitor lamp 48 as a display element for performing the first notification and the second notification. Note that the notification section may display only the first notification using the monitor lamp 48, or may display only the second notification using the monitor lamp 48. In short, the notification unit may perform at least one of the first notification and the second notification using the monitor lamp 48.

As a modified example 8 of this embodiment, the notification circuit 43 may perform the first notification when a person is present. More specifically, in the first function, the notification circuit 43 performs the first notification when a person is present when the usage period Ta reaches the first notification period [Tc]. In this case, the notification control circuit 423 of the control circuit 42 acquires a detection result from the human sensor that detects the presence of a person when the usage period Ta reaches the first notification period [Tc]. Then, when a person is present, the notification control circuit 423 controls the notification circuit 43 to perform the first notification. The notification circuit 43 performs the first notification under the control of the notification control circuit 423. On the other hand, even if the usage period Ta reaches the first notification period [Tc], if no person is present, the notification circuit 43 does not perform the first notification. That is, the notification circuit 43 performs the first notification when a person is present after the use period Ta reaches the first notification period [Tc].

Similarly, the notification circuit 43 may issue a second notification when a person is present. More specifically, in the second function, the notification circuit 43 performs the second notification when a person is present when the uninspected period Tb reaches the second notification period [Td]. In this case, the notification control circuit 423 acquires a detection result from the human sensor that detects the presence of a person when the uninspected period Tb reaches the second notification period [Td]. Then, when a person is present, the notification control circuit 423 controls the notification circuit 43 to perform the second notification. The notification circuit 43 performs the second notification under the control of the notification control circuit 423. On the other hand, even if the uninspected period Tb reaches the second notification period [Td], if no person is present, the notification circuit 43 does not issue the second notification. That is, the notification circuit 43 performs the second notification when a person is present after the uninspected period Tb reaches the second notification period [Td].

As a ninth modification of the present embodiment, the notification circuit 43 may perform the first notification at a predetermined first timing. More specifically, in the first function, the notification circuit 43 performs the first notification at a predetermined first timing when the usage period Ta reaches the first notification period [Tc]. The first timing is a time or time period in which the first notification can be made. For example, the first timing is the time or time period when there are people in the building where the disaster prevention lighting equipment 1 is installed. In modification 9, the control circuit 42 stores in advance a schedule including the first timing. When the usage period Ta reaches the first notification period [Tc], the notification control circuit 423 acquires the current time from the real-time clock and issues a notification to perform the first notification at the first timing according to a predetermined schedule. The circuit 43 is controlled. The notification circuit 43 performs the first notification at the first timing under the control of the notification control circuit 423. As an example, when the first timing is 10 a.m. and the use period Ta reaches the first notification period [Tc], the notification circuit 43 performs the first notification at 10 a.m. In other words, even if the use period Ta reaches the first notification period [Tc], the notification circuit 43 does not issue the first notification until 10 am. As another example, when the first timing is from 7:00 p.m. to 9:00 p.m. (2 hours), when the usage period Ta reaches the first notification period [Tc], the notification circuit 43 The first announcement will be made between 9:00 p.m. and 9:00 p.m. In other words, the notification circuit 43 does not perform the first notification during time periods other than the time period from 7:00 pm to 9:00 pm.

Similarly, the notification circuit 43 may perform the second notification at a predetermined second timing. More specifically, in the second function, the notification circuit 43 performs the second notification at a predetermined second timing when the uninspected period Tb reaches the second notification period [Td]. The second timing is, for example, a time of day or a time period. As an example, when the second timing is 3:00 p.m. and the uninspected period Tb reaches the second notification period [Td], the notification circuit 43 performs the second notification at 3:00 p.m. In other words, even if the uninspected period Tb reaches the second notification period [Td], the notification circuit 43 does not issue the second notification until 3:00 pm. As another example, if the second timing is from 6:00 pm to 10:00 pm (4 hours) and the uninspected period Tb reaches the second notification period [Td], the notification circuit 43 A second announcement will be made between 6:00 and 10:00 p.m. In other words, the notification circuit 43 does not perform the second notification in time slots other than the time slot from 6:00 pm to 10:00 pm.

As a tenth modification of the present embodiment, the first notification period may be shorter than the inspection period specified by law. More specifically, the control circuit 42 stores in advance a period shorter than the inspection period prescribed by law as the first notification period. Then, when the usage period reaches the first notification period, the notification control circuit 423 controls the notification circuit 43 to perform the first notification. The notification circuit 43 performs the first notification under the control of the notification control circuit 423 before the period of use reaches the inspection period specified by law. The notification circuit 43 can perform the first notification at a timing earlier than the inspection timing specified by law. In this case, the first notification period is a period from the start of use of the battery 3 to a time point before the inspection timing. For example, the first notification period is a grace period earlier than the timing when the battery 3 is inspected. The length of the grace period is, for example, less than one week (for example, one day). This allows the inspector to conduct the actual inspection in accordance with the inspection period prescribed by law.

Similarly, the second notification period may be shorter than the inspection period specified by law. More specifically, the notification control circuit 423 stores in advance a period shorter than the inspection period prescribed by law as the second notification period. Then, when the uninspected period reaches the second notification period, the notification control circuit 423 controls the notification circuit 43 to perform the second notification. The notification circuit 43 performs the second notification under the control of the notification control circuit 423 before the non-inspection period reaches the inspection period specified by law. The notification circuit 43 can perform the second notification at a timing earlier than the inspection timing specified by law. In this case, the second notification period is a period from the previous inspection timing to a time point before the next inspection timing. For example, the second notification period is a grace period earlier than the timing for checking the battery 3. The length of the grace period is, for example, less than one week (for example, one day). This allows the inspector to conduct the actual inspection in accordance with the inspection period prescribed by law.

As a modification 11 of the present embodiment, the power supply timer 421 may continue counting until the usage period Ta reaches the life span of the battery 3 instead of until the usage period Ta reaches the first notification period [Tc]. (See imaginary line in Figure 2). More specifically, when the use period Ta reaches the first notification period [Tc], the power supply timer 421 continues to measure time without resetting the time value. Then, when the use period Ta reaches the end of the life period, the notification control circuit 423 controls the notification circuit 43 to issue a notification urging replacement of the battery 3. The notification circuit 43 performs the above notification under the control of the notification control circuit 423. When the usage period Ta reaches the lifetime period, the power supply timer 421 resets the time value. Thereafter, when the battery 3 replacement process is completed, the power supply timer 421 newly starts counting the usage period Ta.

Further, when inspecting an emergency power source such as the battery 3, if the battery 3 cannot maintain discharge for a specified time, the notification control circuit 423 controls the notification unit to issue a notification prompting replacement of the battery 3. May be controlled. The notification circuit 43 performs the above notification under the control of the notification control circuit 423.

As a modification 11 of this embodiment, there may be a disaster prevention lighting system B2 as shown in FIG. The disaster prevention lighting system B2 includes a plurality of (four in the illustrated example) disaster prevention lighting fixtures 1.

In the disaster prevention lighting system B2, each of the plurality of disaster prevention lighting fixtures 1 has a communication function. The lighting device 4 further includes a communication circuit connected to the communication line 8. The communication circuit transmits and receives signals via the communication line 8 . The communication circuit is compliant with a wired LAN (Local Area Network) such as Ethernet (registered trademark) or a standard such as RS-485 (for example, IEEE 802.3 or RS-485), and transmits and transmits signals. Preferably, the signal is received. Therefore, in each lighting device 4 of the plurality of disaster prevention lighting devices 1, the control circuit 42 performs communication via the communication line 8 by controlling the communication circuit, and the control circuit 42 communicates with other lighting devices 4. Data can be exchanged.

Each of the plurality of lighting devices 4 that can communicate via the communication line 8 sends the first notification and second notification to other disaster prevention lighting systems B2 by communicating with other lighting devices 4 other than the own device. conduct.

For example, each control circuit 42 of the plurality of lighting devices 4 transmits data related to notification of inspection time to other lighting devices 4 by controlling respective communication circuits when the period of use reaches the notification period. Furthermore, even when the uninspected period reaches the second notification period, each control circuit 42 similarly transmits data related to notification to the other lighting devices 4 when it is time for the other lighting devices 4 to be inspected. In other lighting devices 4, when the control circuit 42 acquires the above data, the notification control circuit 423 of the control circuit 42 performs the first notification or the second notification. Thereby, the first notification and the second notification can be performed not only in the own device but also in other disaster prevention lighting equipment 1.

Further, each control circuit 42 of the plurality of lighting devices 4 may transmit data regarding the inspection timing of its own device by multicast or broadcast.

Further, each control circuit 42 of the plurality of lighting devices 4 may periodically transmit a data request to other lighting devices 4 by multicast or broadcast. The control circuit 42 that has received the data request returns data regarding the inspection timing of its own device to the lighting device 4 that has transmitted the data request.

Further, the communication circuit may transmit and receive signals by wireless communication. For example, the communication circuit may transmit signals in accordance with standards such as wireless LAN, BLUETOOTH (registered trademark), or ZIGBEE (registered trademark) (e.g., IEEE 802.11, IEEE 802.15.1, or IEEE 802.15.4). and receive signals. In this case, the communication line 8 becomes unnecessary in the disaster prevention lighting system.

Therefore, each of the plurality of lighting devices 4 included in the disaster prevention lighting system B2 can grasp the inspection timing of the other lighting devices 4, and notifies the other lighting devices 4 of the inspection timing of its own device.
