Further, the lighting device 4 preferably further includes a DC power supply circuit 45, a power failure detection circuit 46, a receiving unit 47, a monitor lamp 48, and a push button switch 49. The lighting device 4 includes three push button switches 49. When the three push button switches 49 are distinguished, they are referred to as push button switches 49A, 49B, and 49C, respectively.

  The DC power supply circuit 45 is configured by, for example, a self-excited switching power supply circuit such as a ringing choke converter, and converts an AC voltage supplied from an external power supply (for example, a commercial power system) 9 from an effective value of the AC voltage. Is preferably converted to a low DC voltage. It is preferable that the charging circuit 40 be configured to operate when power is supplied from the external power supply 9 and to flow a charging current from the DC power supply circuit 45 to the battery 3. The power failure detection circuit 46 is configured to detect a power failure of the external power supply 9 from the output voltage of the DC power supply circuit 45 and notify the control circuit 42 of the power failure.

  The monitor lamp 48 includes, for example, a light-emitting diode that emits green light, and emits light by a charging current supplied from the charging circuit 40 to the battery 3. The receiving unit 47 is configured to receive a wireless signal using infrared rays as a communication medium, demodulate a transmission frame from the received wireless signal, and pass the demodulated transmission frame to the control circuit 42. This wireless signal is transmitted from a wireless transmitter operated by an inspector or the like performing an inspection.

  The inspection is performed at intervals specified by laws and regulations, and the purpose is to discharge the battery 3 for a specified time or more, and to check the degree of deterioration of the battery 3. Further, it is preferable that the inspection has a further object of confirming that the lighting circuit 41 is forcibly operated and the light source 2 is maintained in the lighting state for a specified time or more.

(2.4) Lighting Circuit The lighting circuit 41 lights the light source 2 with the power supplied from the battery 3 when the external power supply 9 is stopped. More specifically, the lighting circuit 41 is configured to convert the direct current supplied from the battery 3 into a constant current and supply the constant current to the light source 2.

(2.5) Control Circuit The control circuit 42 operates by being supplied with power from the external power supply 9 or the battery 3. The control circuit 42 is preferably configured by a computer system. The computer system mainly has a processor and a memory as hardware. The function as the control circuit 42 in the present disclosure is realized by the processor executing the program recorded in the memory of the computer system. The program may be recorded in a memory of the computer system in advance. It may be provided through an electric communication line, or may be provided by being recorded on a non-transitory recording medium such as a memory card, an optical disk, or a hard disk drive which can be read by a computer system. A processor of a computer system is composed of one or more electronic circuits including a semiconductor integrated circuit (IC) or a large-scale integrated circuit (LSI). An integrated circuit such as an IC or an LSI referred to here differs depending on the degree of integration, and includes an integrated circuit called a system LSI, a VLSI (Very Large Scale Integration), or a ULSI (Ultra Large Scale Integration). Furthermore, an FPGA (Field-Programmable Gate Array), which is programmed after the manufacture of the LSI, or a logic device capable of reconfiguring the connection relation inside the LSI or reconfiguring the circuit section inside the LSI, is also adopted as a processor. Can be. The plurality of electronic circuits may be integrated on one chip, or may be provided separately on a plurality of chips. The plurality of chips may be integrated in one device, or may be provided separately in a plurality of devices. The computer system referred to here includes a microcontroller having one or more processors and one or more memories. Therefore, the microcontroller is also configured by one or a plurality of electronic circuits including a semiconductor integrated circuit or a large-scale integrated circuit.

  The control circuit 42 is configured to operate the charging circuit 40 and stop the lighting circuit 41 when the power failure detection circuit 46 does not detect a power failure. The control circuit 42 is configured to stop the charging circuit 40 and operate the lighting circuit 41 when the power failure detection circuit 46 detects a power failure. Further, when the push-button switch 49A is pressed, the control circuit 42 determines that an inspection instruction has been issued from an inspector or the like, stops the charging circuit 40, and operates the lighting circuit 41 to operate the battery 3. It is configured to discharge and operate the charging circuit 40. Similarly, when the control circuit 42 receives the transmission frame from the receiving unit 47, it determines that there is an inspection instruction from an inspector or the like, stops the charging circuit 40, and operates the lighting circuit 41 to operate the battery. 3 is configured to be discharged and the charging circuit 40 is operated. However, when the push-button switch 49B is pressed, the control circuit 42 operates the lighting circuit 41 for several seconds, then stops the lighting circuit 41 again, and operates the charging circuit 40. Preferably.

  The disaster prevention lighting fixture 1 is a guide light, an emergency lighting fixture, or the like. Guidance lights and emergency lighting fixtures must be inspected in accordance with the law. The timing for inspection of guide lights is stipulated in the Fire Service Law, and the timing for inspection of emergency lighting equipment is specified in the Building Standards Law.

  Further, if the storage battery mounted on the guide light does not exceed a predetermined number of years from the year of manufacture, the above-described inspection may not be performed on the guide light in consideration of the life of the storage battery. In this case, if the storage battery mounted on the guide light has exceeded a predetermined number of years from the year of manufacture, the above-described inspection needs to be performed on the guide light in consideration of the life of the storage battery. For example, when the storage battery is a nickel-cadmium battery, if the storage battery has been manufactured for more than three years, an inspection needs to be performed. When the storage battery is a nickel-metal hydride battery, if the storage battery has been manufactured for more than five years, an inspection needs to be performed.

  However, it is difficult to say that the inspection is performed at an appropriate time (for example, a time determined by laws and regulations). Therefore, the disaster prevention lighting device 1 according to the present embodiment has the following notification function in order to perform inspection at an appropriate time in consideration of the life of the storage battery.

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

  The control circuit 42 is configured to have a function of a power supply timer 421 and a function of an inspection timer 422. When the control circuit 42 has a real-time clock (RTC), the power supply timer 421 and the inspection timer 422 periodically read the value of the real-time clock and accumulate the count value to measure the elapsed time. Perform timing operation. Alternatively, the power supply timer 421 and the inspection timer 422 may be counters that perform a timekeeping operation by incrementing a count value at a fixed cycle (for example, a cycle of a clock frequency).

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

  Alternatively, when the control circuit 42 operates only with the emergency power, the control circuit 42 may detect the execution of the replacement work of the battery 3 based on whether or not the emergency power is supplied. For example, immediately before the voltage of the transmission path of the emergency power falls below the operating voltage of the control circuit 42 and the operation of the control circuit 42 stops, the control circuit 42 outputs the time information immediately before the stop based on the value of the real-time clock. Remember. Then, immediately after the voltage of the transmission path of the emergency power exceeds the operating voltage of the control circuit 42 and the operation of the control circuit 42 is restarted, the control circuit 42 determines the time information immediately after the restart based on the value of the real-time clock. To get. The control circuit 42 obtains the stop time during which the operation has been stopped from the difference between the time information immediately before the stop and the time information immediately after the restart, and detects the replacement of the battery 3 if the stop time is longer than a certain time. Then, the power supply timer 421 is reset.

  The inspection timer 422 measures a period from completion of the inspection for discharging the battery 3 as an uninspection period Tb. More specifically, the inspection timer 422 clocks the non-inspection period Tb after the inspection is performed, in order to determine when to perform the inspection again on the same battery 3. When the inspection timer 422 starts counting the unchecked period Tb, the counted value of the unchecked period Tb increases with time from zero. Further, the inspection timer 422 is reset when the inspection is performed, and the counted value becomes zero. Similarly, the inspection timer 422 is reset when the battery 3 is replaced, and the time value becomes zero. In the present embodiment, the person simultaneously presses the push button switches 49A and 49C after the inspection and after the replacement of the battery 3. When the push-button switches 49A and 49C are simultaneously pressed, the control circuit 42 resets the inspection timer 422. Alternatively, when the control circuit 42 performs the inspection, the control circuit 42 may reset the power timer 421. After a reset, the timing value increases again from zero.

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

  The notification control circuit 423 performs a first notification control process for causing the notification circuit 43 to perform the first notification using the time value of the power timer 421. The notification control circuit 423 stores data of the first notification period [Tc] in advance, and performs a comparison process between the use 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 is a notification that is performed when the usage period Ta measured by the power timer 421 reaches the first notification time [Tc]. The first notification period [Tc] is a check period defined by laws and regulations, for example, a period corresponding to three years or five years.

  In addition, the notification control circuit 423 performs a second notification control process that causes the notification circuit 43 to perform the second notification using the time value of the inspection timer 422. The notification control circuit 423 stores data of the second notification period [Td] in advance, and performs a comparison process between the unchecked period Tb and the second notification period [Td]. Then, when the unchecked 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 notification performed when the unchecked period Tb measured by the check timer 422 reaches the second notification period [Td]. The second notification period [Td] is an inspection period defined 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 performing a first notification and a second function of performing a second notification. The notification circuit 43 performs the first notification and the 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 by light when the usage period Ta measured by the power timer 421 reaches the first notification period [Tc]. In addition, the notification circuit 43 performs the second notification by light when the unchecked period Tb measured by the check timer 422 reaches the second notification period [Td].

  The notification circuit 43 is a notification unit 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 by 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 timer 421 continues to count the use period Ta even if the battery 3 is checked before the use period Ta reaches the first notification period [Tc]. In other words, before the use period Ta reaches the first notification period [Tc], the power supply timer 421 continues to count the use period Ta regardless of whether or not the battery 3 is checked.

  On the other hand, if the check of the battery 3 is performed before the unchecked period Tb reaches the second notification period [Td], the check timer 422 resets the time value of the unchecked period Tb. In other words, if the battery 3 is not checked before the unchecked period Tb reaches the second notification period [Td], the check timer 422 continues to count the unchecked period Tb. When performed, the inspection timer 422 resets the time value of the non-inspection period Tb.

(3) Operation of Disaster Prevention Lighting Fixture Hereinafter, the operation of the disaster prevention lighting fixture 1 according to the present embodiment will be described with reference to FIG.

  First, in the lighting device 4, when the supply of the emergency power from the control circuit 42 is started, the control circuit 42 determines that the charging of the battery 3 is started, and starts time measurement of the use period Ta by the power timer 421 ( (Time t0). When the power timer 421 starts counting the usage period Ta, the count value of the usage period Ta increases with time from zero.

  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 performed, the inspector performs the inspection E1 of the battery 3 (time t2). When the inspection E1 is completed, the inspection timer 422 starts measuring the unchecked period Tb (time t3). When the non-inspection period Tb reaches the second notification period [Td] (time t4), the notification circuit 43 performs the second notification N2. When the second notification N2 is performed, the inspector performs the inspection E2 (time t5). When the inspection E2 is completed, the inspection timer 422 is reset, and the measurement of the non-inspection period Tb by the inspection timer 422 is started (time t6). Then, if the replacement process of the battery 3 is not performed, the unchecked period Tb reaches the second notification period [Td] again, and the notification circuit 43 performs the second notification N2. When the second notification N2 is performed, the inspector performs the inspection E2. When the inspection E2 is completed, the inspection timer 422 is reset, and the measurement of the non-inspection period Tb by the inspection timer 422 is started.

  On the other hand, if the replacement process C1 for replacing the battery 3 is performed before the unchecked period Tb reaches the second notification period [Td], the power timer 421 and the check timer 422 are reset (time t7). When the replacement process C1 is completed, the power supply timer 421 starts measuring the usage period Ta (time t8). Thereafter, the same operation as described above is repeated.

  That is, in the lighting device 4, even when the inspection is not performed by the inspector, the use period Ta of the battery 3 is set to the first notification period [Tc] (for example, 3 years or 5 years determined by law or the like). , The first notification N1 is performed. Therefore, the lighting device 4 performs the first notification N1 at an appropriate time in consideration of the life of the battery 3 and the like.

  The lighting device 4 periodically performs 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 when the use period Ta is started to when the first notification N1 is performed. Then, when the battery 3 is not replaced after the first inspection, the lighting device 4 performs the second notification N2. Therefore, the lighting device 4 can prompt an inspection at an appropriate time in consideration of the life of the battery 3 and the like. Note that the control circuit 42 acquires the current time from the real-time clock and, in accordance with a predetermined schedule, in a time zone that can be notified (for example, a time zone in which a person is present in the building where the disaster prevention lighting fixture 1 is installed). It is preferable to execute the notification operation.

The notification unit includes, for example, a sounding unit such as a piezoelectric sounder, and a sound drive circuit that drives the sounding unit to emit a notification sound or a notification message.

  The notification unit performs the first notification and the second notification based on the output of the notification sound from the sounding unit. The notification sound may be a buzzer sound such as "Peepy" or a voice message such as "Please check." Upon hearing the notification sound, the inspector can operate the wireless transmitter or the push button switch 49A to execute the inspection. 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.

  In addition, the notification unit of the lighting device 4 may perform the first notification by light and perform the second notification by sound, or may perform the first notification by sound and perform the second notification by light.

Is also good. That is, the usage period Ta may be an elapsed time since the battery 3 is mounted. In this case, a detection element is provided for detecting 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 defined as the start of the use period.

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

  As a fifth modification of the present embodiment, the notification unit of the lighting device 4 may perform the first notification and the second notification by 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, changes the light color of the light source 2 periodically, or blinks the light source 2. In addition, the notification unit may perform the first notification using the light source 2 and perform the second notification using the display element. Alternatively, the notification unit may perform the first notification using the display element and 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 by light using the light source 2.

  When at least one of the first notification and the second notification is performed, the notification unit first dimmes and lights (or blinks) the light source 2 with a light amount lower or higher than that in the emergency, and keeps the light source 2 constant from the start of lighting. After a lapse of time, the light source 2 may be turned on (or blinked) with the same light amount as the emergency lighting. Alternatively, the notification unit may gradually increase the light amount of 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 turns on (or blinks) the display element 431, and after a predetermined time has elapsed from the start of turning on the display element 431, the light source 2. May be turned on (or blinking). The dimming level at the time of 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 by light using at least one of the plurality of light emitting elements of the light source 2. The light source 2 includes a plurality of light emitting elements. Note that the notification unit may perform the first notification using at least one of the plurality of light-emitting elements, and perform the second notification using the display element. Alternatively, the notification unit may perform the first notification using the display element and 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 by light using the plurality of light emitting elements of the light source 2.

  As a seventh modification of the present embodiment, the notification unit of the lighting device 4 may use the monitor lamp 48 as a display element for performing the first notification and the second notification. The notification unit 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 modification example 8 of the present embodiment, the notification circuit 43 may perform the first notification when a person is present. More specifically, in the first function, when the use period Ta reaches the first notification period [Tc], if the presence of a person is present, the notification circuit 43 performs the first notification. In this case, the notification control circuit 423 of the control circuit 42 acquires a detection result from a human sensor that detects the presence of a person when the use period Ta reaches the first notification period [Tc]. 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 according to the control of the notification control circuit 423. On the other hand, even when the use period Ta reaches the first notification period [Tc], the notification circuit 43 does not perform the first notification when there is no person. That is, the notification circuit 43 performs the first notification when the person is present after the use period Ta reaches the first notification period [Tc].

  Similarly, the notification circuit 43 may perform the second notification when a person is present. More specifically, in the second function, when the uninspected period Tb reaches the second notification period [Td], the notification circuit 43 performs the second notification when a person is present. In this case, the notification control circuit 423 acquires a detection result from a human sensor that detects the presence of a person when the unchecked period Tb has reached 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 according to the control of the notification control circuit 423. On the other hand, even when the unchecked period Tb has reached the second notification period [Td], when there is no person, the notification circuit 43 does not perform the second notification. That is, the notification circuit 43 performs the second notification when there is a person after the unchecked 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, when the use period Ta reaches the first notification period [Tc], the notification circuit 43 performs the first notification at a predetermined first timing. The first timing is a time or a time zone where the first notification is possible. For example, the first timing is a time or a time zone when a person is in a building where the disaster prevention lighting fixture 1 is installed. In the ninth modification, the control circuit 42 stores a schedule including the first timing in advance. When the use period Ta reaches the first notification period [Tc], the notification control circuit 423 obtains the current time from the real-time clock, and notifies 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 according to the control by the notification control circuit 423. As an example, when the first timing is 10:00 am, when the use period Ta reaches the first notification period [Tc], the notification circuit 43 performs the first notification at 10:00 am. In other words, even if the use period Ta reaches the first notification period [Tc], the notification circuit 43 does not perform the first notification until 10:00 am. As another example, when the first timing is a time zone (2 hours) from 7:00 pm to 9:00 pm, when the use period Ta reaches the first notification period [Tc], the notification circuit 43 outputs The first notification is performed from time to 9:00 pm. In other words, the notification circuit 43 does not perform the first notification in a time period 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, when the non-inspection period Tb reaches the second notification period [Td], the notification circuit 43 performs the second notification at a predetermined second timing. The second timing is, for example, a time or a time zone. As an example, when the second timing is 3:00 pm, when the unchecked period Tb reaches the second notification period [Td], the notification circuit 43 performs the second notification at 3:00 pm. In other words, even if the unchecked period Tb reaches the second notification period [Td], the notification circuit 43 does not perform the second notification until 3:00 pm. As another example, when the second timing is a time period (4 hours) from 6:00 pm to 10:00 pm, when the unchecked period Tb reaches the second notification period [Td], the notification circuit 43 outputs The second notification is performed during the time period from 6:00 to 10:00 pm. In other words, the notification circuit 43 does not perform the second notification in a time period other than the time period from 6:00 pm to 10:00 pm.

  As a tenth modification of the present embodiment, the first notification period may be a period shorter than the inspection period specified by law. More specifically, the control circuit 42 stores in advance a period shorter than the inspection period stipulated 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 according to the control by the notification control circuit 423 before the use period reaches the inspection period specified by law. The notification circuit 43 can perform the first notification at a timing earlier than the inspection timing stipulated by law. In this case, the first notification period is a period from the start of use of the battery 3 to a point before the inspection timing. For example, the first notification period is a timing earlier by the grace period than the timing when the battery 3 is checked. The length of the grace period is, for example, less than one week (for example, one day). This allows the inspector to perform an actual inspection so as to match the inspection period specified by law.

  Similarly, the second notification period may be a period 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 stipulated by law as a second notification period. Then, when the unchecked 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 according to 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 stipulated by law. In this case, the second notification period is a period from the previous inspection timing to a point before the next inspection timing. For example, the second notification period is a timing earlier by the grace period than the timing when the battery 3 is checked. The length of the grace period is, for example, less than one week (for example, one day). This allows the inspector to perform an actual inspection so as to match the inspection period specified by law.

  As a modification 11 of the present embodiment, the power timer 421 may continue the time measurement not until the use period Ta reaches the first notification period [Tc] but until the use period Ta reaches the life period of the battery 3. (See phantom lines in FIG. 2). More specifically, the power timer 421 continues to count time without resetting the count value when the use period Ta reaches the first notification period [Tc]. Then, when the use period Ta reaches the life period, the notification control circuit 423 controls the notification circuit 43 so as to notify that the replacement of the battery 3 is prompted. The notification circuit 43 performs the notification according to the control of the notification control circuit 423. When the use period Ta reaches the life period, the power timer 421 resets the clock value. Thereafter, when the replacement process of the battery 3 is completed, the power supply timer 421 newly starts measuring the usage period Ta.

  Further, in the inspection of the emergency power supply such as the battery 3, when the battery 3 cannot maintain the discharge for a specified time, the notification control circuit 423 causes the notification unit to notify the user of replacement of the battery 3. It may be controlled. The notification circuit 43 performs the notification according to the control of the notification control circuit 423.

  As a modification 11 of the present embodiment, there may be a disaster prevention lighting system B2 as shown in FIG. The disaster prevention lighting system B2 includes a plurality (four in the illustrated example) of 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 transmits and receives signals in accordance with a wired LAN (Local Area Network) such as Ethernet (registered trademark) or a standard such as RS-485 (eg, IEEE 802.3 or RS-485). Preferably, signal reception is performed. Therefore, in each lighting device 4 of the plurality of disaster prevention lighting fixtures 1, the control circuit 42 performs communication via the communication line 8 by controlling the communication circuit, and the control circuit 42 communicates with the other lighting devices 4. Data can be exchanged.

  Then, each of the plurality of lighting devices 4 communicable via the communication line 8 communicates with the other lighting devices 4 other than the own device, thereby providing the first notification and the second notification to the other disaster prevention lighting system B2. Do.

  For example, each control circuit 42 of the plurality of lighting devices 4 controls the communication circuit, and when the usage period reaches the notification period, transmits data on notification of the inspection time to the other lighting devices 4. Similarly, when the unchecked period reaches the second notification period, each control circuit 42 also transmits data on notification to the other lighting devices 4 to the other lighting devices 4 at the time of the inspection. In another lighting device 4, when the control circuit 42 acquires the 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 on the own device but also on the other disaster prevention lighting fixture 1.

  Further, each control circuit 42 of the plurality of lighting devices 4 may transmit data on the inspection time of the 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 on the inspection time of the own device to the lighting device 4 that has transmitted the data request.

  In addition, the communication circuit may perform signal transmission and signal reception by wireless communication. For example, the communication circuit transmits a signal in accordance with a standard such as wireless LAN, BLUETOOTH (registered trademark), or ZIGBEE (registered trademark) (for example, IEEE 802.11, IEEE 802.15.1, or IEEE 802.15.4). And a signal is received. In this case, the communication line 8 is not required for 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 time of the other lighting device 4, and the other lighting device 4 notifies the inspection time of the own device.
