By the way, regarding the guide lights included in the disaster prevention lighting equipment (see Japanese Industrial Standards C 8105-2-22: 201422.3.22A), the requirements for inspection of the built-in emergency power supply have been relaxed. In other words, if the emergency power source is a nickel-cadmium storage battery, inspection is not necessary in principle from the year of manufacture until more than 3 years have passed. In addition, if the emergency power source is a nickel-metal hydride storage battery, inspection is not necessary in principle from the year of manufacture until more than 5 years have passed (Firefighting Preliminary No. 80 "Regarding partial revision of test standards and inspection procedures for firefighting equipment, etc." Notice) ”).

The above-mentioned disaster prevention lighting equipment 1 is a disaster prevention lighting equipment such as a guide light or an emergency lighting equipment. Guide lights and emergency lighting fixtures must be inspected in accordance with laws and regulations. The timing of inspection of guide lights is stipulated in the Fire Service Act, and the timing of inspection of emergency lighting equipment is stipulated in the Building Standards Act.

Further, if the storage battery mounted on the guide light does not exceed a predetermined number of years from the year of manufacture, it may not be necessary to carry out the above-mentioned inspection 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 exceeds a predetermined number of years from the manufacturing year, it is necessary to carry out the above-mentioned inspection on the guide light in consideration of the life of the storage battery. For example, when the storage battery is a nickel-cadmium battery, it is necessary to carry out an inspection if the storage battery has been manufactured for more than 3 years. If the storage battery is a nickel-metal hydride battery, it is necessary to carry out an inspection if the storage battery has been manufactured for more than 5 years.

However, it is difficult to say that the inspection is carried out at an appropriate time (for example, a time specified by law). Therefore, the disaster prevention lighting fixture 1 of the present embodiment has the following notification function and automatic inspection 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 fixture 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 carry out an inspection on the disaster prevention lighting fixture 1. Therefore, the control circuit 42 performs the following notification control processing and inspection control processing 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, an inspection timer 422, an instrument timer 423, a notification control circuit 424, and an inspection control circuit 425.

When the control circuit 42 is equipped with an RTC (Real Time Clock), the power supply timer 421, the inspection timer 422, and the instrument timer 423 periodically read the RTC value and accumulate the count values. Performs a timekeeping operation to time the time. Alternatively, the power supply timer 421, the inspection timer 422, and the instrument timer 423 may be counters that perform a timekeeping operation by incrementing the count value at a fixed cycle (for example, a clock frequency cycle).

Hereinafter, the notification control and the automatic inspection control will be described with reference to FIG.

The power timer 421 measures the power usage period Ta, which is the usage period of the battery 3. In the present embodiment, the power supply usage period Ta is the elapsed time from the time when the power supply from the external power supply 9 to the lighting device 4 is started. However, the starting point of the power supply usage period Ta may be the time when the unused battery 3 attached to the disaster prevention lighting fixture 1 is fully charged by the charging circuit 40. Then, when the power timer 421 starts the time measurement of the power supply usage period Ta, the time measurement time [Ta] of the power supply usage period Ta increases from zero with the passage of time. Further, the power timer 421 is reset when the battery 3 is replaced with a new battery 3, and the time counting time [Ta] becomes zero. The power timer 421 is not reset when the inspection is performed. In the present embodiment, the inspector or the administrator simultaneously presses the push button switches 49A and 49B after replacing the battery 3. The control circuit 42 resets the power timer 421 when the push button switches 49A and 49B are pressed at the same time. After resetting the power timer 421, the clock time [Ta] 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 the presence or absence of the supply of the emergency power. For example, the control circuit 42 stores the time information immediately before the stop based on the RTC value just 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. I will do it. Then, 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 obtains the time information immediately after the restart based on the RTC value. 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 if the stop time is a certain time or more, the battery 3 is replaced. Detects and resets the power timer 421.

The inspection timer 422 measures the period after the inspection for discharging the battery 3 is completed as the uninspected period Tb. The uninspected period Tb is used to determine when to perform the inspection again for the same battery 3 (the second and subsequent inspections for the same battery 3 and hereinafter referred to as re-inspection) after the inspection is performed. Used. When the inspection timer 422 starts timing of the uninspected period Tb, the timed time [Tb] of the uninspected period Tb increases from zero with the passage of time. Further, the inspection timer 422 is reset when the inspection is executed or the battery 3 is replaced, and the time counting time [Tb] becomes zero. In the present embodiment, the inspector or the administrator simultaneously presses the push button switches 49A and 49C after the inspection and after the replacement of the battery 3. The control circuit 42 resets the inspection timer 422 when the push button switches 49A and 49C are pressed at the same time. Alternatively, the control circuit 42 may reset the inspection timer 422 when the control circuit 42 performs the inspection. Alternatively, the control circuit 42 may reset the inspection timer 422 in the same manner as the power timer 421 when the battery 3 replacement work is performed. After reset, the clock time [Tb] increases again from zero.

The fixture timer 423 measures the fixture usage period Tc, which is the usage period of the disaster prevention lighting fixture 1. In the present embodiment, the appliance use period Tc is the elapsed time from the time when the power supply from the external power source 9 to the lighting device 4 is started. However, the starting point of the device usage period Tc may be the time when the new battery 3 is fully charged by the charging circuit 40. Then, when the instrument timer 423 starts timing the instrument use period Tc, the time counting time [Tc] of the instrument use period Tc increases from zero with the passage of time. The instrument timer 423 is not reset when the inspection is performed.

Then, the notification control circuit 424 controls the notification circuit 43 based on the time counting times [Ta], [Tb], and [Tc]. In other words, the notification circuit 43 performs notification according to the time counting times [Ta], [Tb], and [Tc]. The notification control circuit 424 uses the time counting time [Ta] of the power supply timer 421 to perform inspection notification control for causing the notification circuit 43 to perform inspection notification. The notification control circuit 424 uses the time counting time [Tb] of the inspection timer 422 to perform re-inspection notification control for causing the notification circuit 43 to perform re-inspection notification. The notification control circuit 424 uses the time counting time [Tc] of the instrument timer 423 to perform exchange notification control for causing the notification circuit 43 to perform exchange notification and exchange re-notification control for causing the notification circuit 43 to perform exchange re-notification.

Further, the inspection control circuit 425 performs automatic inspection control for automatically executing the inspection by controlling the charging circuit 40 and the lighting circuit 41 based on the time counting times [Ta], [Tb], and [Tc].

When the inspection control circuit 425 executes the inspection, if the battery 3 is in a fully charged state, the charging circuit 40 is stopped and the lighting circuit 41 is operated to operate the light source 2 for a predetermined predetermined time. Steady lighting (for example, all lighting). If the battery 3 is not in the fully charged state, the inspection control circuit 425 first operates the charging circuit 40 to make the battery 3 fully charged, and then stops the charging circuit 40 for a predetermined predetermined time. In addition, the lighting circuit 41 is operated to constantly turn on the light source 2 (for example, all lights are turned on). That is, the inspection control circuit 425 discharges the battery 3 when the inspection is executed. Further, in the inspection control circuit 425, if the battery 3 is not in a fully charged state, the charging circuit 40 is operated to charge the battery 3, and the lighting circuit 41 is operated for a predetermined predetermined time to charge the battery. 3 may be discharged.

Further, the inspection control circuit 425 may stop the charging circuit 40 and operate the lighting circuit 41 to keep the light source 2 constantly lit (for example, fully lit) regardless of the charging state of the battery 3. Further, in the inspection control circuit 425, if the charge amount of the charging circuit 40 is sufficiently smaller than the discharge amount to the lighting circuit 41 (for example, trickle charging), the charging circuit 40 is not stopped and the lighting circuit 41 is operated to operate the light source 2. It may be constantly lit (for example, all lit).

Then, the inspection control circuit 425 is used for disaster prevention based on the voltage value of the battery 3 and the current value flowing through the light source 2 at the time when the specified time (20 minutes, 30 minutes or 60 minutes) has elapsed from the start of the inspection. The lighting fixture 1 is inspected, and the inspection result is notified from the notification circuit 43. For example, if the inspection control circuit 425 determines that the battery 3 is deteriorated and the battery 3 is not normal (abnormal), the inspection control circuit 425 notifies by lighting or blinking the display element 431. Further, if the inspection control circuit 425 determines that the light source 2 is deteriorated and the light source 2 is not normal (abnormal), the inspection control circuit 425 notifies by lighting or blinking of the display element 431. It is preferable that the lighting or blinking of the display element 431 performed when the abnormality notification of the battery 3 is performed and the lighting or blinking of the display element 431 performed when the abnormality notification of the light source 2 is performed are different from each other. The lighting device 4 may notify by voice that the light source 2 or the battery 3 is to be replaced.

Further, the inspection control circuit 425 may determine that the battery 3 is normal if the lighting circuit 41 is operating normally when a predetermined time has elapsed from the start of the inspection. The inspection control circuit 425 may determine that the battery 3 is not normal (abnormal) if the lighting circuit 41 is not operating normally due to a decrease in the output voltage of the battery 3 when the specified time has elapsed. ..

Hereinafter, the inspection notification control, the re-inspection notification control, the replacement notification control, the replacement re-notification control, and the automatic inspection notification control will be described in detail with reference to FIG.

The notification control circuit 424 uses the time counting time [Ta] of the power supply timer 421 to perform inspection notification control for causing the notification circuit 43 to perform inspection notification. The inspection notification in the present specification means a notification that urges a person to carry out the first inspection of the battery 3. The notification control circuit 424 stores data of the inspection notification time ([T1], [T11], etc. described later) in advance, and compares the time counting time [Ta] with the inspection notification time [T1], [T11], etc. Perform processing. Then, when the time counting time [Ta] reaches the inspection notification time [T1], [T11], or the like, the notification control circuit 424 controls the notification circuit 43 so as to perform inspection notification.

Further, the notification control circuit 424 uses the time counting time [Tb] of the inspection timer 422 to perform re-inspection notification control for causing the notification circuit 43 to perform re-inspection notification. The re-inspection notification in the present specification means a notification that urges a person to carry out a second and subsequent inspections (re-inspection) of the battery 3. The notification control circuit 424 stores data of the re-inspection notification time ([T2], [T21], etc. described later) in advance, and sets the time counting time [Tb] and the re-inspection notification time [T2], [T21], etc. Performs comparison processing. Then, when the time counting time [Tb] reaches the re-inspection notification time [T2], [T21], or the like, the notification control circuit 424 controls the notification circuit 43 so as to perform re-inspection notification. At this time, the re-inspection notification time [T2], [T21], etc. are preferably shorter than the inspection notification time [T1]. For example, the re-inspection notification time [T2], [T21], etc. is an inspection period stipulated by law, and is, for example, an arbitrary period of 6 months or less or 12 months or less.

Further, the notification control circuit 424 uses the time counting time [Tc] of the instrument timer 423 to perform exchange notification control for causing the notification circuit 43 to perform exchange notification. The exchange notification in the present specification means a notification that prompts a person to replace the disaster prevention lighting fixture 1. The notification control circuit 424 stores the data of the exchange notification time [T3] in advance, and performs a comparison process between the time counting time [Tc] and the exchange notification time [T3]. Then, when the time counting time [Tc] reaches the exchange notification time [T3], the notification control circuit 424 controls the notification circuit 43 so as to perform exchange notification. The replacement notification time [T3] is a predetermined period based on the life of the disaster prevention lighting fixture 1, and is a period corresponding to, for example, 10 years.

Further, the notification control circuit 424 uses the time counting time [Tc] of the instrument timer 423 to perform exchange re-notification control for causing the notification circuit 43 to perform exchange re-notification. The replacement re-notification in the present specification means a notification that urges a person to replace the disaster prevention lighting fixture 1 more strongly than the re-inspection notification. The notification control circuit 424 stores the data of the instrument life time [T4] in advance, and performs a comparison process between the time counting time [Tc] and the instrument life time [T4]. Then, when the time counting time [Tc] reaches the instrument life time [T4], the notification control circuit 424 controls the notification circuit 43 so as to perform replacement re-notification. The fixture life time [T4] is a predetermined period based on the life of the disaster prevention lighting fixture 1, for example, a period equivalent to 15 years.

The notification circuit 43 performs inspection notification, re-inspection notification, replacement notification, and replacement re-notification according to the control by the notification control circuit 424 of the control circuit 42. Specifically, the notification circuit 43 performs inspection notification by light when the time counting time [Ta] of the power supply usage period Ta reaches the inspection notification time [T1], [T11], or the like. Further, when the time counting time [Tb] of the uninspected period Tb reaches the re-inspection notification [T2], [T21], etc., the notification circuit 43 performs re-inspection notification by light. Further, the notification circuit 43 performs replacement notification by light when the time counting time [Tc] of the instrument use period Tc reaches the replacement notification time [T3]. Further, the notification circuit 43 performs replacement re-notification by light when the time counting time [Tc] of the equipment usage period Tc reaches the equipment life time [T4].

The notification circuit 43 performs inspection notification, re-inspection notification, replacement notification, and replacement re-notification by light using the display element 431. For example, the notification circuit 43 may perform inspection notification, re-inspection notification, replacement notification, and replacement re-notification by blinking the display element 431, and may perform inspection notification, re-inspection notification, replacement notification, and replacement re-notification. , It may be performed by lighting the display element 431.

In the time chart of FIG. 2, when the power supply from the external power supply 9 to the lighting device 4 is started, the control circuit 42 starts timing the power supply usage period Ta by the power supply timer 421 (time t0). When the power timer 421 starts timing the power usage period Ta, the clock time [Ta] increases from zero with the passage of time.

After that, when the time counting time [Ta] reaches the inspection notification time [T1] (time t1), the notification circuit 43 performs the inspection notification N1. The inspection notification time [T1] is an inspection period stipulated by law, and is a period corresponding to, for example, 3 years or 5 years. The inspection control circuit 425 of the control circuit 42 executes the inspection E1 of the battery 3 when the first delay time [Td1] elapses after the inspection notification N1 is executed (for example, started) (time t2). Alternatively, the inspection control circuit 425 may execute the inspection E1 when the time counting time [Ta] reaches [T1] + [Td1]. Further, the inspector may perform the inspection E1 after the inspection notification N1 is executed.

The power timer 421 continues to measure the power supply usage period Ta even if the battery 3 is inspected before the time counting time [Ta] reaches the inspection notification time [T1]. In other words, until the time counting time [Ta] reaches the inspection notification period [T1], the power timer 421 continues to measure the power supply usage period Ta regardless of whether the battery 3 is inspected or not.

When the inspection E1 is completed, the inspection timer 422 starts measuring the uninspected period Tb (time t3). When the inspection timer 422 starts timing the uninspected period Tb, the clock time [Tb] increases from zero with the passage of time. When the time counting time [Tb] reaches the re-inspection notification time [T2] (time t4), the notification circuit 43 performs the re-inspection notification N2. The inspection control circuit 425 executes the inspection E2 (re-inspection) of the battery 3 (time t5) when the second delay time [Td2] elapses after the re-inspection notification N2 is executed (for example, started). Alternatively, the inspection control circuit 425 may execute the inspection E2 when the time counting time [Tb] reaches [T2] + [Td2]. Further, the inspector may perform the inspection E2 of the battery 3 after the re-inspection notification N2 is executed.

The control circuit 42 preferably has a first delay time [Td1] and a second delay time [Td2] of less than 12 months (for example, 2 months). The first delay time [Td1] and the second delay time [Td2] may be either the same time or different times from each other. The cycle of inspection E2 (corresponding to [T2] + [Td2]) is the time ([T1] + [Td1]) from the start of time counting of the power supply usage period Ta until the first inspection E1 is executed. Equivalent)

When the inspection E2 is completed, the inspection timer 422 is reset, and the timing of the uninspected period Tb by the inspection timer 422 is started (time t6). If the battery 3 replacement process is not executed, the time counting time [Tb] reaches the re-inspection notification time [T2] again, and the notification circuit 43 performs the re-inspection notification N2. When the second delay time [Td2] elapses after the re-inspection notification N2 is executed, the inspection E2 is executed. When the inspection E2 is completed, the inspection timer 422 resets the time counting time [Tb], and the timing of the uninspected period Tb by the inspection timer 422 is started. After that, the re-inspection notification N2 and the inspection E2 are repeated until the battery 3 or the disaster prevention lighting fixture 1 is replaced. The re-inspection notification time [T2] may be shortened as the number of times the re-inspection notification N2 is executed increases.

On the other hand, if the battery replacement C1 for replacing the battery 3 is executed before the non-inspection period Tb reaches the re-inspection notification time [T2], the power supply timer 421 and the inspection timer 422 are reset (time t7). When the battery replacement C1 is completed, the power timer 421 starts measuring the power usage period Ta (time t8).

That is, the lighting device 4 has reached the inspection notification time [T1] (for example, 3 years or 5 years determined by laws and regulations) even when the inspector does not inspect the lighting device 4. After that, the inspection notification N1 is performed. Therefore, the lighting device 4 can perform the inspection notification N1 at an appropriate time in consideration of the life of the battery 3 and the like.

Further, after the inspection notification N1 is performed, the lighting device 4 repeatedly repeats the re-inspection notification N2 until the battery 3 is replaced. That is, if the battery 3 is not replaced after the inspection E1 (first inspection), the lighting device 4 performs a re-inspection notification N2. As a result, the lighting device 4 can prompt the inspection at an appropriate time in consideration of the life of the battery 3 and the like.

Further, even if the lighting device 4 is not inspected by the inspector, after the power supply usage period Ta reaches a predetermined time (for example, 3 years or 5 years determined by laws and regulations), the lighting device 4 is used. Inspection E1 is automatically executed. Therefore, the lighting device 4 can automatically perform the inspection at an appropriate time in consideration of the life of the battery 3 and the like.

Further, after the inspection E1 is performed, the lighting device 4 repeatedly executes the inspection E2 until the battery 3 is replaced. That is, if the battery 3 is not replaced after the inspection E1 (first inspection), the lighting device 4 automatically executes the inspection E2 (re-inspection). As a result, the lighting device 4 can automatically perform the inspection at an appropriate time in consideration of the life of the battery 3 and the like. The control circuit 42 acquires the current time from the RTC, and inspects E1 in a time zone that can be inspected (for example, a time zone in which there are no people in the building where the disaster prevention lighting fixture 1 is installed) according to a predetermined schedule. , E2 is preferred.

Here, the disaster prevention luminaire 1 needs to encourage a person to replace the disaster prevention luminaire 1 itself in consideration of not only the life of the battery 3 but also the life of parts other than the battery 3. The parts other than the battery 3 are resin parts such as a cover, a computer system included in the control circuit 42, a solid-state light emitting element such as an LED included in the light source 2, and an electric component included in the lighting circuit 41. Therefore, the notification control circuit 424 uses the time counting time [Tc] of the instrument timer 423 to perform exchange notification control for causing the notification circuit 43 to perform exchange notification, and prompts a person to replace the disaster prevention lighting equipment 1. Further, when the disaster prevention lighting fixture 1 is not replaced by the replacement notification, the notification control circuit 424 uses the time counting time [Tc] of the equipment timer 423 to cause the notification circuit 43 to perform replacement re-notification. To encourage people to replace the disaster prevention lighting fixture 1 more strongly than the replacement notification.

In the time chart of FIG. 2, when the power supply from the external power source 9 to the lighting device 4 is started, the control circuit 42 starts measuring the fixture usage period Tc by the fixture timer 423 (time t0). When the instrument timer 423 starts timing the instrument usage period Tc, the time counting time [Tc] increases from zero with the passage of time.

After that, when the time counting time [Tc] reaches the exchange notification time [T3] (time t21), the notification circuit 43 performs the exchange notification N3. The exchange notification N3 is a notification that prompts a person to replace the disaster prevention lighting fixture 1. The exchange notification time [T3] is longer than the inspection notification time [T1]. In FIG. 2, after the replacement notification N3 is performed, the battery replacement C1 for replacing the battery 3 is executed instead of replacing the disaster prevention lighting fixture 1 (time t7). The power timer 421 is reset when the battery replacement C1 is executed. When the battery replacement C1 is completed, the power timer 421 starts timing the power usage period Ta, and the clock time [Ta] increases from zero with the passage of time (time t8).

When the battery replacement C1 is performed after the replacement notification N3 is executed, the notification control circuit 424 performs the inspection notification N1 using the inspection notification time [T11] instead of the inspection notification time [T1]. The inspection notification time [T11] is shorter than the inspection notification time [T1]. When the inspection notification time [T1] is 5 years, the inspection notification time [T11] is, for example, 3 years. When the inspection notification time [T1] is 3 years, the inspection notification time [T11] is, for example, 2 years. After the exchange notification N3, the notification circuit 43 performs the inspection notification N1 when the time counting time [Ta] reaches the inspection notification time [T11] (time t9). That is, when the battery 3 is replaced without replacing the disaster prevention lighting fixture 1 after the replacement notification N3, the inspection notification time [T11] for the replaced battery 3 is the inspection notification time [T1] for the battery 3 before replacement. Will be shorter than.

The inspection control circuit 425 executes the inspection E1 of the battery 3 (time t10) when the first delay time [Td1] elapses after the inspection notification N1 is executed (for example, started). Alternatively, the inspection control circuit 425 may execute the inspection E1 when the time counting time [Ta] reaches [T11] + [Td1]. Further, the inspector may perform the inspection E1 after the inspection notification N1 is executed.

The above-mentioned inspection notification time [T11] is shorter than the inspection notification time [T1]. Therefore, the lighting device 4 can perform the inspection notification N1 on the disaster prevention lighting fixture 1 that has been used for a long time at an early stage in consideration of the life of the disaster prevention lighting fixture 1.

The power timer 421 continues to measure the power supply usage period Ta even if the battery 3 is inspected before the time counting time [Ta] reaches the inspection notification time [T11]. In other words, until the time counting time [Ta] reaches the inspection notification period [T11], the power timer 421 continues to measure the power supply usage period Ta regardless of whether the battery 3 is inspected or not.

When the inspection E1 is completed, the inspection timer 422 starts measuring the uninspected period Tb (time t11). When the inspection timer 422 starts timing the uninspected period Tb, the clock time [Tb] increases from zero with the passage of time. When the time counting time [Tb] reaches the re-inspection notification time [T21] (time t12), the notification circuit 43 performs the re-inspection notification N2. The re-inspection notification time [T21] is shorter than the re-inspection notification time [T2]. That is, when the battery 3 is replaced without replacing the disaster prevention lighting fixture 1 after the time counting time [Tc] reaches the replacement notification time [T3], the re-inspection notification time [T21] for the replaced battery 3 is set. It is shorter than the inspection notification time [T2] of the battery 3 before replacement. Further, the re-inspection notification time [T21] may be the same length as the inspection notification time [T3].

After that, until the disaster prevention lighting fixture 1 is replaced and the disaster prevention lighting fixture 1 is no longer used (for the same disaster prevention lighting fixture 1), the notification control circuit 424 has an inspection notification time and re-inspection every time the battery 3 is replaced. It is preferable that the notification time is shorter than that before the replacement of the battery 3. If the disaster prevention lighting fixture 1 is not replaced, the lighting device 4 performs the inspection notification N1, the re-inspection notification N2, and the inspections E1 and E2 in the same manner as described above.

In the time chart of FIG. 2, when the time counting time [Tc] reaches the instrument life time [T4] (time t22), the replacement re-notification N4 is performed. The replacement re-notification N4 is a notification that the usage time of the disaster prevention lighting fixture 1 has reached the end of its useful life, and the replacement of the disaster prevention lighting fixture 1 is strongly urged as compared with the replacement notification N3. The instrument life time [T4] is longer than the replacement notification time [T3]. For example, if the replacement notification time [T3] is 10 years, the instrument life time [T4] is 15 years. In FIG. 2, after the replacement re-notification N4 is performed, the fixture replacement D1 for replacing the disaster prevention lighting fixture 1 is executed (time t13). When the fixture replacement D1 is completed, the same processing as described above is performed in the disaster prevention lighting fixture 1 after the replacement.

Therefore, the lighting device 4 prompts the replacement of the disaster prevention lighting fixture 1 by the replacement notification N3 for the disaster prevention lighting fixture 1 that has been used for a long time. That is, the lighting device 4 can notify the replacement time of the disaster prevention lighting device 1. Further, in the lighting device 4, the disaster prevention lighting fixture 1 is not replaced even if the replacement notification N3 is performed, and when the usage time reaches the useful life, the replacement of the disaster prevention lighting fixture 1 is performed by the replacement re-notification N4 rather than the replacement notification N3. Strongly urge. As a result, there is a high possibility that the disaster prevention lighting fixture 1 that has reached the end of its useful life will be replaced.

Further, it is preferable that the notification control circuit 424 further shortens the inspection notification time when the time counting time [Tc] of the instrument usage period Tc reaches the instrument life time [T4]. In FIG. 2, when the time counting time [Tc] reaches the instrument life time [T4], the notification control circuit 424 reaches the current inspection notification time [T21] and the timing time [Tc] reaches the instrument life time [T4]. Make it shorter than before. In this case, the lighting device 4 can prompt the replacement of the disaster prevention lighting fixture 1 whose usage time has reached the end of its useful life as soon as possible.

Further, in the inspection of an emergency power source such as the battery 3, if the battery 3 cannot maintain the discharge for a specified time, the notification control circuit 424 notifies the notification unit to prompt the replacement of the battery 3. You may control it. The notification circuit 43 performs the notification according to the control by the notification control circuit 424.

That is, the main body 10 has a ceiling material so as to sandwich the ceiling material between the pair of supports 12 inserted into the embedding holes provided in the ceiling and the flange 100 provided on the lower end surface of the main body 10. Supported by the material.

As shown in FIGS. 3A to 3C, the cover 11 is formed in a disk shape larger than the outer diameter of the flange 100 of the main body 10. As shown in FIG. 3B, a circular window hole 110 is provided in the center of the cover 11. The lens 21 of the light source unit 2U penetrates the window hole 110. A pair of mounting springs are attached to the cover 11. As shown in FIG. 3C, the cover 11 is held by the main body 10 in a state where the bottom surface of the main body 10 is closed by a pair of mounting springs.

A lighting device 4 (see FIG. 1), a light source 2 (see FIG. 1), and a battery 3 (see FIG. 1) are attached to the main body 10. More specifically, as shown in FIG. 3B, the light source unit 2U, the battery unit 3U, and the lighting unit 4U are housed in the main body 10. However, the battery unit 3U is housed in the main body 10 so that it can be inserted and removed through the opening on the bottom surface of the main body 10.

As shown in FIG. 3B, the light source unit 2U includes an LED module 20 and a lens 21. The LED module 20 has a substrate on which a light source 2 is mounted, and emits white illumination light such as white, neutral white, or daylight color by applying a voltage in the forward direction. The lens 21 is arranged in front of (below) the LED module 20 and collects the light emitted from the LED module 20.

The battery unit 3U shown in FIG. 3B has a battery 3 including a plurality of elementary batteries (see FIG. 1) and a battery case for accommodating the battery 3. The battery 3 is, for example, a nickel-hydrogen storage battery or a nickel-cadmium storage battery. The battery case is made of a material having electrical insulation such as synthetic resin in a box shape, and accommodates a plurality of elementary batteries inside.

The lighting unit 4U shown in FIG. 3B has a lighting device 4 (see FIG. 1). The light radiated from the monitor lamp 48 of the lighting device 4 is emitted to the front (downward) of the cover 11 through the first hole 111 provided in the cover 11. The receiving unit 47 receives (receives) a radio signal through the second hole 112 provided in the cover 11. The light radiated from the display element 431 of the notification circuit 43 is emitted to the front (downward) of the cover 11 through the third hole 114 provided in the cover 11. The push buttons of the three push button switches 49A, 49B, and 49C are arranged so as to face each of the three operation holes 113 provided in the cover 11.

(Disaster prevention lighting system)
FIG. 4 shows the configuration of the disaster prevention lighting system B1 of the present embodiment. The disaster prevention lighting system B1 includes a plurality of disaster prevention lighting fixtures 1.

In the disaster prevention lighting system B1, each of the plurality of disaster prevention lighting fixtures 1 has a communication function. The lighting device 4 further includes a communication circuit (not shown) connected to the communication line 8, and the communication circuit transmits and receives a signal via the communication line 8. The communication circuit transmits signals and conforms to 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). It is preferable to receive the signal. Therefore, each lighting device 4 of the plurality of disaster prevention lighting fixtures 1 communicates via the communication line 8, and the control circuit 42 can exchange data with the other lighting devices 4.

Then, each of the plurality of lighting devices 4 capable of communicating via the communication line 8 communicates with other lighting devices 4 other than the own device, so that the delay times [Td1] and [Td2] of the own device are [Td2] (FIG. 2). Refer to).

For example, each notification control circuit 424 of the plurality of lighting devices 4 has data regarding the inspection timing of the other lighting device 4 from the control circuit 42 of the other lighting device 4 (next inspection timing and delay time [Td1], [ Each data) such as Td2] is acquired. The acquisition timing is every predetermined time, or before the delay time [Td1] or the delay time [Td2] of the own device is set. Therefore, each notification control circuit 424 of the plurality of lighting devices 4 sets the delay times [Td1] and [Td2] of the own device so that the inspection timing of the own device does not overlap with the inspection timing of the other lighting devices 4. can.

Further, each notification control circuit 424 of the plurality of lighting devices 4 transmits data related to the inspection timing of the own device (next inspection timing and each data such as delay times [Td1] and [Td2]) by multicast or broadcast. You may. The transmission timing is, for example, when the delay time [Td1] or the delay time [Td2] is set. In this case, each of the plurality of lighting devices 4 can easily acquire the data of the delay times [Td1] and [Td2] in the other lighting devices 4.

Further, each notification control circuit 424 of the plurality of lighting devices 4 may periodically transmit a data request to another lighting device 4 by multicast or broadcast. Upon receiving the data request, the notification control circuit 424 uses the data related to the inspection timing of its own device (next inspection timing and each data such as delay times [Td1] and [Td2]) as the lighting device 4 of the data request transmission source. Reply to.

Further, the communication circuit of the lighting device 4 may transmit and receive signals by wireless communication. For example, the communication circuit transmits signals in accordance with standards such as wireless LAN, BLUETOOTH®, or ZIGBEE® (eg, IEEE 802.11, IEEE 802.15.1, or IEEE 802.15.4). And receive the signal. In this case, the disaster prevention lighting system does not require the communication line 8.

Therefore, each of the plurality of lighting devices 4 of the disaster prevention lighting system B1 can grasp the inspection timing of the other lighting devices 4, and can set the inspection timing (delay time [Td1], [Td2]) of the own device to the other lighting devices. It can be flexibly set so as not to overlap with the inspection timing of 4.

(First modification)
In the lighting device 4 of the first modification, the battery replacement C1 is performed before the replacement notification N3, and the inspection notification N1 is performed after the replacement notification N3. In this case, the timing at which the notification circuit 43 performs the inspection notification N1 differs depending on the timing of the battery replacement C1.

As shown in FIGS. 5A and 5B, it is assumed that the battery 3 is replaced before the time counting time [Tc] of the instrument usage period Tc reaches the replacement notification time [T3]. In this case, the notification circuit 43 performs inspection notification at the earlier of the following first notification timing and second notification timing.

First notification timing: The timing at which the inspection notification time [T1] elapses after the battery 3 is replaced.

Second notification timing: The timing at which the inspection notification time [T11] elapses after the time counting time [Tc] of the instrument usage period Tc reaches the replacement notification time [T3].

In FIGS. 5A and 5B, the inspection notification time [T1] is 5 years, the inspection notification time [T11] is 3 years, and the replacement notification time [T3] is 10 years.

In FIG. 5A, the battery replacement C1 was performed when the clock time [Ta] was [Ta1] (= 9 years). In this case, the first notification timing is the timing (time t31) when the inspection notification time [T1] (= 5 years) has elapsed since the battery 3 was replaced, and the time counting time [Tc] at the time t31 is [Tc1]. (Approximately 14 years ≒ 9 years + 5 years). The second notification timing is the timing (time t32) obtained by adding the inspection notification time [T11] (= 3 years) to the exchange notification time [T3] (= 10 years), and is the time counting time [Tc] at the time t32. ] Becomes [Tc2] (about 13 years ≒ 10 years + 3 years). Therefore, since the second notification timing (time t32) is earlier than the first notification timing (time t31), the notification circuit 43 performs inspection notification at the time t31 when the time counting time [Tc] reaches [Tc2] (about 13 years). I do.

In FIG. 5B, the battery replacement C1 was performed when the clock time [Ta] was [Ta2] (= 6 years). In this case, the first notification timing is the timing (time t33) when the inspection notification time [T1] (= 5 years) has elapsed since the battery 3 was replaced, and the time counting time [Tc] at the time t33 is [Tc3]. (Approximately 11 years ≒ 6 years + 5 years). Further, the second notification timing is the time t32 as in FIG. 5A, and the time counting time [Tc] at the time t32 is [Tc2] (about 13 years ≈ 10 years + 3 years). Therefore, since the first notification timing (time t33) is earlier than the second notification timing (time t32), the notification circuit 43 is inspected and notified at the time t33 when the time counting time [Tc] reaches [Tc3] (about 11 years). I do.

Therefore, in the lighting device 4, the first notification timing and inspection by the inspection notification time [T1] are set as the timing of the first replacement notification performed after the time counting time [Tc] of the appliance use period Tc reaches the replacement notification time [T3]. Of the second notification timings according to the notification time [T11], whichever is earlier is adopted. As a result, the exchange notification that is first performed after the time counting time [Tc] reaches the exchange notification time [T3] can be executed earlier.

(Second modification)
In the lighting device 4 of the second modification, the start timings of the power supply usage period Ta, which is the usage period of the battery 3, and the appliance usage period Tc, which is the usage period of the disaster prevention lighting fixture 1, are different from those in the above-described embodiment.

Specifically, the power supply usage period Ta and the appliance usage period Tc are the elapsed time from the time when the battery 3 is manufactured, instead of the elapsed time from the time when the power supply from the external power supply 9 to the lighting device 4 is started. You may. In this case, at the time of manufacturing the battery 3, a recording medium such as an ID chip or an IC tag that stores the battery information including the manufacturing date or the elapsed time from the manufacturing date is attached to the battery 3. When the notification control circuit 424 is electrically connected to the battery 3, the battery information is read from the recording medium, and the time counting times [Ta] and [Tc] of the power supply usage period Ta and the equipment usage period Tc are obtained. ] Set the initial value. 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.

Alternatively, the power supply usage period Ta and the appliance usage period Tc may be the elapsed time from the time when the battery 3 is attached, instead of the elapsed time from the time when the power supply from the external power supply 9 to the lighting device 4 is started. good. That is, the power supply usage period Ta and the appliance usage period Tc may be the elapsed time since the battery 3 is mounted. In this case, a detection element 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 is provided. When the detection element detects that the above two connection terminals are connected, it is defined as each start timing of the power supply usage period Ta and the equipment usage period Tc.

Alternatively, the power supply usage period Ta and the appliance usage period Tc are based on at least two of the time when the power supply from the external power supply 9 to the lighting device 4 is started, the time when the battery 3 is manufactured, and the time when the battery 3 is attached. It may be each elapsed time from the obtained timing.

Further, it is preferable that the power timer 421 clocks the power usage period Ta when power is supplied from at least one of the external power source 9 and the battery 3 when the time is started. Further, it is preferable that the instrument timer 423 clocks the instrument usage period Tc when power is supplied from at least one of the external power source 9 and the battery 3 when the instrument timer 423 starts timing.

(Third modification example)
In the lighting device 4 of the third modification, the notification unit includes the light source 2, and the notification unit uses the light emitted by the light source 2 to perform inspection notification N1, re-inspection notification N2, replacement notification N3, and replacement re-notification N4. You may do at least one of. In this case, the notification control circuit 424 controls the lighting circuit 41 and changes the lighting state of the light source 2 to perform notification. For example, the notification control circuit 424 periodically changes the amount of light of the light source 2, switches the light color of the display element 431, periodically changes the light color of the light source 2, or causes the light source 2 to blink. Or something. The notification unit uses the display element 431 to perform a part of the inspection notification N1, the re-inspection notification N2, the replacement notification N3, and the replacement re-notification N4, and uses the light source 2 to perform the inspection notification N1, the re-inspection notification N2, and the re-inspection notification N2. The rest of the exchange notification N3 and the exchange re-notification N4 may be performed.

Further, when performing at least one of the inspection notification N1, the re-inspection notification N2, the replacement notification N3, and the replacement re-notification N4, the notification unit first adjusts the light source 2 with a light amount lower or higher than that of the emergency lighting. The light may be turned on (or blinked), and after a certain period of time has elapsed from the start of lighting, the light source 2 may be turned on (or blinked) with the same amount of light as the lighting in an emergency. Alternatively, when performing at least one of the inspection notification N1, the re-inspection notification N2, the replacement notification N3, and the replacement re-notification N4, the notification unit gradually increases the amount of light of the light source 2 with the passage of time. You may. Alternatively, the notification unit first turns on (or blinks) the display element 431 when performing at least one of the inspection notification N1, the re-inspection notification N2, the replacement notification N3, and the replacement re-notification N4, and the display element 431. The light source 2 may be turned on (or blinked) after a certain period of time has elapsed from the start of lighting. 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%.

Further, at least one of the display element 431 and the light source 2 may have a plurality of light emitting elements. In this case, the notification unit performs at least one of the inspection notification N1, the re-inspection notification N2, the replacement notification N3, and the replacement re-notification N4 with light using at least one of the plurality of light emitting elements, and the inspection notification N1, The rest of the re-inspection notification N2, the replacement notification N3, and the replacement re-notification N4 may be performed using the display element.

Further, the notification unit may use the monitor lamp 48 as a display element for performing at least one of the inspection notification N1, the re-inspection notification N2, the replacement notification N3, and the replacement re-notification N4.

(Fourth modification)
As a fourth modification of the present embodiment, the notification circuit 43 has an inspection notification N1, a re-inspection notification N2, a replacement notification N3, and a replacement re-notification N4 when a person is present in the building in which the disaster prevention lighting fixture 1 is installed. May be done. In this case, the notification control circuit 424 of the control circuit 42 acquires the detection result from the motion sensor that detects the presence of a person in the building, and obtains the detection result of the motion sensor in the timekeeping time [Ta], [Tb]. , [Tc] to perform inspection notification N1, re-inspection notification N2, replacement notification N3, and replacement re-notification N4.

More specifically, the notification circuit 43 performs the inspection notification N1 when the time counting time [Ta] of the power supply usage period Ta reaches the inspection notification times [T1] and [T11] and there is a person. For example, the notification control circuit 424 acquires a detection result from a motion sensor that detects the presence of a person when the timing time [Ta] reaches the inspection notification times [T1] and [T11]. Then, when a person is present, the notification control circuit 424 controls the notification circuit 43 so as to perform the inspection notification N1. The notification circuit 43 performs inspection notification N1 according to the control by the notification control circuit 424. On the other hand, even when the time counting time [Ta] reaches the inspection notification times [T1] and [T11], the notification circuit 43 does not perform the inspection notification N1 when no person is present. That is, the notification circuit 43 performs the inspection notification N1 when a person is present after the time counting time [Ta] reaches the inspection notification times [T1] and [T11].

Similarly, the notification circuit 43 performs the re-inspection notification N2 when the time counting time [Tb] of the uninspected period Tb reaches the re-inspection notification time [T2] and [T21] and there is a person. For example, the notification control circuit 424 acquires a detection result from a motion sensor that detects the presence of a person when the time counting time [Tb] reaches the re-inspection notification times [T2] and [T21]. Then, when a person is present, the notification control circuit 424 controls the notification circuit 43 so as to perform the re-inspection notification N2. The notification circuit 43 performs re-inspection notification N2 according to the control by the notification control circuit 424. On the other hand, even when the time counting time [Tb] reaches the re-inspection notification time [T2] and [T21], the notification circuit 43 does not perform the re-inspection notification N2 when no person is present. That is, after the time counting time [Tb] reaches the re-inspection notification time [T2] and [T21], the notification circuit 43 performs the re-inspection notification N2 when a person is present.

Similarly, the notification circuit 43 performs the exchange notification N3 when the time counting time [Tc] of the instrument use period Tc reaches the exchange notification time [T3] and there is a person. For example, the notification control circuit 424 acquires a detection result from a motion sensor that detects the presence of a person when the time counting time [Tc] reaches the exchange notification time [T3]. Then, when a person is present, the notification control circuit 424 controls the notification circuit 43 so as to perform the exchange notification N3. The notification circuit 43 performs the exchange notification N3 according to the control by the notification control circuit 424. On the other hand, even when the time counting time [Tc] reaches the exchange notification time [T3], the notification circuit 43 does not perform the exchange notification N3 when no person is present. That is, the notification circuit 43 performs the exchange notification N3 when a person is present after the time counting time [Tc] reaches the exchange notification time [T3].

Similarly, the notification circuit 43 performs replacement re-notification N4 when the time counting time [Tc] of the equipment use period Tc reaches the equipment life time [T4] and there is a person. For example, the notification control circuit 424 acquires a detection result from a motion sensor that detects the presence of a person when the time counting time [Tc] reaches the instrument life time [T4]. Then, when a person is present, the notification control circuit 424 controls the notification circuit 43 so as to perform exchange re-notification N4. The notification circuit 43 performs exchange re-notification N4 according to the control by the notification control circuit 424. On the other hand, even when the time counting time [Tc] reaches the instrument life time [T4], the notification circuit 43 does not perform the replacement re-notification N4 when no person is present. That is, the notification circuit 43 performs replacement re-notification N4 when a person is present after the time counting time [Tc] reaches the instrument life time [T4].

Even if the notification circuit 43 performs at least one of the inspection notification N1, the re-inspection notification N2, the replacement notification N3, and the replacement re-notification N4 when a person is present in the building where the disaster prevention lighting fixture 1 is installed. good.

(Fifth modification)
As a fifth modification of the present embodiment, the control circuit 42 acquires the current time from the RTC, and according to a predetermined schedule, a person can be notified in a time zone (for example, in a building where the disaster prevention lighting fixture 1 is installed). It is preferable to execute at least one of the inspection notification N1, the re-inspection notification N2, the replacement notification N3, and the replacement re-notification N4 during the time zone in which the above is present.

For example, the notification circuit 43 may perform the inspection notification N1 at a predetermined first timing. More specifically, the notification circuit 43 performs inspection notification N1 at a predetermined first timing when the time measurement time [Ta] of the power supply usage period Ta reaches the inspection notification time [T1] and [T11]. .. The first timing is a time or time zone in which inspection notification N1 is possible. For example, the first timing is the time or time zone when a person is in the building where the disaster prevention lighting fixture 1 is installed. In the fifth modification, the control circuit 42 stores the schedule including the first timing in advance. When the time counting time [Ta] reaches the inspection notification time [T1] and [T11], the notification control circuit 424 acquires the current time from the RTC and sends the inspection notification N1 at the first timing according to a predetermined schedule. The notification circuit 43 is controlled so as to do so. The notification circuit 43 performs the inspection notification N1 at the first timing according to the control by the notification control circuit 424. As an example, when the first timing is 10:00 am and the time counting time [Ta] reaches the inspection notification times [T1] and [T11], the notification circuit 43 performs the inspection notification N1 at 10:00 am. In other words, even if the time counting time [Ta] reaches the inspection notification time [T1] and [T11], the notification circuit 43 does not perform the inspection notification N1 until 10:00 am. As another example, when the first timing is in the time zone (2 hours) from 7:00 pm to 9:00 pm, and when the time counting time [Ta] reaches the inspection notification time [T1] and [T11], the notification circuit. 43 performs inspection notification N1 in the time zone from 7:00 pm to 9:00 pm. In other words, the notification circuit 43 does not perform the inspection notification N1 in a time zone other than the time zone from 7:00 pm to 9:00 pm.

Similarly, the notification circuit 43 may perform re-inspection notification at a predetermined second timing. More specifically, the notification circuit 43 re-inspects the notification N2 at a predetermined second timing when the time counting time [Tb] of the uninspected period Tb reaches the re-inspection notification times [T2] and [T21]. I do. The third timing is, for example, a time or a time zone. As an example, when the second timing is 3:00 pm, when the time counting time [Tb] reaches the re-inspection notification time [T2] and [T21], the notification circuit 43 performs the re-inspection notification N2 at 3:00 pm. .. In other words, even if the time counting time [Tb] reaches the re-inspection notification time [T2] and [T21], the notification circuit 43 does not perform the re-inspection notification N2 until 3:00 pm. As another example, when the second timing is in the time zone (4 hours) from 6:00 pm to 10:00 pm, when the time counting time [Tb] reaches the re-inspection notification time [T2] or [T21], the notification is notified. The circuit 43 performs the re-inspection notification N2 in the time zone from 6:00 pm to 10:00 pm. In other words, the notification circuit 43 does not perform the re-inspection notification N2 in a time zone other than the time zone from 6:00 pm to 10:00 pm.

Similarly, the notification circuit 43 may perform the exchange notification N3 at a predetermined third timing. More specifically, the notification circuit 43 performs the exchange notification N3 at a predetermined third timing when the time counting time [Tc] of the instrument use period Tc reaches the exchange notification time [T3]. The third timing is, for example, a time or a time zone. As an example, when the third timing is 3:00 pm, when the time counting time [Tc] reaches the exchange notification time [T3], the notification circuit 43 performs the exchange notification N3 at 3:00 pm. In other words, even if the time counting time [Tc] reaches the exchange notification time [T3], the notification circuit 43 does not perform the exchange notification N3 until 3:00 pm. As another example, when the third timing is in the time zone (4 hours) from 6:00 pm to 10:00 pm, when the clock time [Tc] reaches the exchange notification time [T3], the notification circuit 43 is set in the afternoon. The exchange notification N3 is performed during the time period from 6:00 to 10:00 pm. In other words, the notification circuit 43 does not perform the exchange notification N3 in a time zone other than the time zone from 6:00 pm to 10:00 pm.

Similarly, the notification circuit 43 may perform exchange re-notification N4 at a predetermined fourth timing. More specifically, the notification circuit 43 performs replacement re-notification N4 at a predetermined fourth timing when the time counting time [Tc] of the equipment usage period Tc reaches the equipment life time [T4]. The fourth timing is, for example, a time or a time zone. As an example, when the fourth timing is 3:00 pm and the time counting time [Tc] reaches the instrument life time [T4], the notification circuit 43 performs replacement re-notification N4 at 3:00 pm. In other words, even if the time counting time [Tc] reaches the instrument life time [T4], the notification circuit 43 does not perform the replacement re-notification N4 until 3:00 pm. As another example, when the fourth timing is in the time zone (4 hours) from 6:00 pm to 10:00 pm, when the clock time [Tc] reaches the instrument life time [T4], the notification circuit 43 is set in the afternoon. Exchange re-notification N4 will be performed from 6:00 to 10:00 pm. In other words, the notification circuit 43 does not perform the exchange re-notification N4 in a time zone other than the time zone from 6:00 pm to 10:00 pm.

(6th modification)
As a sixth modification of the present embodiment, it is preferable that the inspection control circuit 425 of the control circuit 42 sets the delay times [Td1] and [Td2] as follows.

For example, it is preferable that each length of the delay times [Td1] and [Td2] is, for example, a value randomly set from a value within a predetermined range. In this case, the inspection control circuit 425 has a random number generator (random number generation function). When the time counting time [Ta] reaches the inspection notification time [T1], the inspection control circuit 425 obtains the length (value) of the delay time [Td1] corresponding to the random number generated by the random number generator. Then, the inspection control circuit 425 executes the inspection E1 when the delay time [Td1] elapses after the time counting time [Ta] reaches the inspection notification time [T1]. Further, in the inspection control circuit 425, when the time counting time [Tb] reaches the re-inspection notification time [T2] and [T21], the length (value) of the delay time [Td2] corresponding to the random number generated by the random number generator. Ask for. Then, the inspection control circuit 425 executes the inspection E2 when the delay time [Td2] has elapsed after the time counting time [Ta] reaches the re-inspection notification times [T2] and [T21].

Further, each length of the delay times [Td1] and [Td2] may be, for example, a value peculiar to the lighting device 4. In this case, the values unique to the lighting device 4 are the lengths of the delay times [Td1] and [Td2] according to the serial number of the lighting device 4, the setting contents such as the DIP switch, the setting signal transmitted from the outside, and the like. Set as a switch.

The remaining capacity of the battery 3 after the inspection is performed is smaller than the remaining capacity of the battery 3 before the inspection is performed. Therefore, if a power failure occurs in the external power supply 9 after the inspection is executed, the lighting time of the light source 2 is shortened due to insufficient capacity of the battery 3. As a result, when a plurality of disaster prevention luminaires 1 are installed and the execution timings of the respective inspections of the plurality of disaster prevention luminaires 1 are the same, the lighting time of the light source 2 is shortened in all the disaster prevention luminaires 1. Emergency lighting is not secured.

On the other hand, in the sixth modification, when a plurality of disaster prevention lighting fixtures 1 are installed, the timing at which each of the plurality of disaster prevention lighting fixtures 1 executes the inspection can be staggered from each other. As a result, when a power failure occurs in the external power supply 9, all or most of the plurality of disaster prevention lighting fixtures 1 can sufficiently maintain the lighting time of the light source 2, and the plurality of disaster prevention lighting fixtures 1 are installed. In some cases, emergency lighting is ensured.

(7th modification)
In the inspection control circuit 425 of the seventh modification, the light source 2 may be dimmed and lit when the inspection is executed. In this case, the inspection control circuit 425 keeps the light source 2 constantly lit (for example, fully lit) when the external power supply 9 fails. Then, the inspection control circuit 425 makes the light source 2 dimmed and lit by lowering or increasing the light output of the light source 2 at the time of inspection as compared with the case of steady lighting. The inspection control circuit 425 can dimm the light source 2 by controlling the output of the lighting circuit 41. 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%.

If the dimming level is less than 100%, the time required for inspection will be longer, but the light output of the light source 2 will be smaller, so that the lighting device 4 will mislead the people around the disaster prevention lighting device 1. It is possible to suppress the occurrence and carry out the inspection. That is, it is less likely that people around the disaster prevention lighting fixture 1 mistake the lighting of the light source 2 at the time of inspection for the lighting in an emergency.

When the dimming level exceeds 100%, the time required for inspection is shorter, but the light output of the light source 2 is larger, so that the lighting device 4 misleads the people around the disaster prevention lighting device 1. It is possible to suppress the occurrence and carry out the inspection. That is, it is less likely that people around the disaster prevention lighting fixture 1 mistake the lighting of the light source 2 at the time of inspection for the lighting in an emergency.

(8th modification)
The inspection control circuit 425 of the eighth modification may perform an inspection using a dummy load. In this case, the disaster prevention luminaire 1 includes a dummy load including a resistor in parallel with the light source 2 and a switch for electrically connecting the output of the lighting circuit 41 to the light source 2 or the dummy load so as to be switchable. The inspection control circuit 425 electrically connects the output of the lighting circuit 41 to the light source 2 during normal times and power outages.

Then, when the inspection is executed, the inspection control circuit 425 executes the inspection after electrically connecting the output of the lighting circuit 41 to the dummy load. That is, the light source 2 does not light up when the inspection is executed. Therefore, since it is possible to prevent the light source 2 of the disaster prevention lighting fixture 1 from being turned on except during a power failure, the lighting device 4 performs the inspection while suppressing the occurrence of a situation that misleads the people around the disaster prevention lighting fixture 1. be able to.

The notification unit may continuously output the notification sound or intermittently output the notification sound when performing the inspection notification N1 and the re-inspection notification N2.

The notification unit may perform the exchange notification N3 by outputting the notification sound from the sounding unit. The notification sound may be a buzzer sound such as "peepy" or a voice message such as "10 years have passed. It is recommended to replace the equipment." When the inspector hears the notification sound, the disaster prevention lighting fixture 1 can be replaced. The notification unit may continuously output the notification sound or intermittently output the notification sound when the exchange notification N3 is performed.

The notification unit may perform exchange re-notification N4 by outputting the notification sound from the sounding unit. The notification sound may be a buzzer sound such as "peepy" or a voice message such as "The service life of the device has expired. Please replace the device." Upon hearing the notification sound, the inspector can recognize that the need to replace the disaster prevention lighting fixture 1 has increased, and can replace the disaster prevention lighting fixture 1. The notification unit may continuously output the notification sound or intermittently output the notification sound when performing the exchange re-notification N4.

It is preferable that the notification unit performs at least one of the inspection notification N1, the re-inspection notification N2, the replacement notification N3, and the replacement re-notification N4 by the identifier. Identifiers are, for example, characters such as "It's time for inspection", "Please inspect", and "The service life of the equipment has expired. Please replace the equipment." Or a symbol or pattern such as "x", or a combination of characters, symbols or patterns.

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

Alternatively, the notification unit may have a display unit such as a liquid crystal display. The above display is provided on the main body 10, for example, "It is time for inspection", "Please inspect", and "The service life of the equipment has expired. Please replace the equipment." Characters such as, or symbols such as "○" or "×" are displayed.

It should be noted that each of the inspection notification N1, the re-inspection notification N2, the replacement notification N3, and the replacement re-notification N4 may be realized by using any one of light, sound, identifier, watermark, and display as the notification medium. Further, the notification media of the inspection notification N1, the re-inspection notification N2, the replacement notification N3, and the replacement re-notification N4 may be the same as each other.
