The disaster prevention lighting equipment 1 is a guide light, an emergency lighting equipment, or the like. Guidance lights and emergency lighting fixtures must be inspected as required by law. The Fire Service Law stipulates the timing for inspection of guide lights, and the Building Standards Law stipulates the timing for inspection of emergency lighting equipment.

Furthermore, if a predetermined number of years has not passed since the manufacturing year of the storage battery mounted on the guide light, it may not be necessary to carry out the above-described inspection of the guide light in consideration of the life of the storage battery. In this case, if the predetermined number of years has passed since the manufacturing year of the storage battery mounted on the guide light, it is necessary to carry out the above-described inspection of the guide light in consideration of the life of the storage battery. For example, if the storage battery is a nickel-cadmium battery, it must be inspected if it is more than three years old from the date of manufacture of the storage battery. In addition, if the storage battery is a nickel-metal hydride battery, if five years have passed since the production year of the storage battery, it is necessary to carry out an inspection.

However, in reality, it is difficult to say that inspections are performed at appropriate times (for example, at times specified by laws and regulations). Therefore, the disaster prevention lighting fixture 1 according to the present embodiment has the following notification function in order to perform inspection at an appropriate time considering 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, the disaster prevention lighting fixture 1 does not need to be inspected. Therefore, the control circuit 42 controls the notification circuit 43 so as to perform notification after the usage 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 timer 421 and the inspection timer 422 periodically read the value of the real time clock and integrate the count value to measure the elapsed time. Performs timing operation. Alternatively, the power timer 421 and the inspection timer 422 may be counters that perform timekeeping operations by incrementing the count value at a constant cycle (for example, the cycle of the clock frequency).

The power timer 421 counts the usage period Ta of the battery 3 . In the present embodiment, the usage period Ta is the elapsed time from when the charging circuit 40 starts charging the battery 3 . The starting point of the usage period Ta is, for example, the time when charging of the new battery 3 is started. However, the starting point of the usage period Ta may be the time when the new battery 3 is fully charged by the charging circuit 40 . Then, when the power source timer 421 starts counting the usage period Ta, the counted value of the usage period Ta increases from zero as time elapses. Also, the power timer 421 is reset when the battery 3 is replaced with a new battery 3, and the measured value becomes zero. In this embodiment, a person presses the pushbutton switches 49A and 49B at the same time after the battery 3 is replaced. The control circuit 42 resets the power timer 421 when the pushbutton switches 49A and 49B are pressed simultaneously. After the power timer 421 is reset, the clock value increments again from zero.

Alternatively, when the control circuit 42 operates only with emergency power, the control circuit 42 may detect the replacement of the battery 3 based on the presence or absence of supply of emergency power. For example, immediately before the operation of the control circuit 42 stops due to the voltage of the emergency power transmission path falling below the operating voltage of the control circuit 42, the control circuit 42 acquires time information immediately before the stop based on the value of the real-time clock. Remember. 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 outputs 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 was stopped from the difference between the time information immediately before the stop and the time information immediately after the restart. and reset the power timer 421 .

The inspection timer 422 counts the period after the inspection for discharging the battery 3 is completed as the non-inspection period Tb. More specifically, the inspection timer 422 counts the non-inspection period Tb in order to determine when to inspect the same battery 3 again after the inspection is performed. When the inspection timer 422 starts timing the non-inspection period Tb, the measured value of the non-inspection period Tb increases from zero with the passage of time. Also, the inspection timer 422 is reset to zero when the inspection is performed. Similarly, the inspection timer 422 is reset when the battery 3 is replaced, and the measured value becomes zero. In this embodiment, a person presses the push button switches 49A and 49C at the same time after the inspection and after the battery 3 is replaced. The control circuit 42 resets the inspection timer 422 when the pushbutton switches 49A and 49C are pressed simultaneously. Alternatively, the control circuit 42 may reset the power timer 421 when the control circuit 42 performs inspection. After reset, the timer value increments again from zero.

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

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

The first notification in this specification refers to a notification that is made when the period of use Ta counted by the power timer 421 reaches the first notification time [Tc]. The first notification period [Tc] is an inspection period stipulated by law, and is a period corresponding to, for example, three years or five years.

In addition, the notification control circuit 423 uses the time value of the inspection timer 422 to perform a second notification control process for causing the notification circuit 43 to perform the second notification. The notification control circuit 423 stores data of the second notification period [Td] in advance, and performs comparison processing between the non-inspection period Tb and the second notification period [Td]. Then, when the non-inspection period Tb reaches the second notification period [Td], the notification control circuit 423 controls the notification circuit 43 to perform the second notification.

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

(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 according to the control by the notification control circuit 423 of the control circuit 42 . More specifically, as the first function, the notification circuit 43 performs the first notification with light when the usage period Ta counted by the power timer 421 reaches the first notification period [Tc]. In addition, when the non-inspection period Tb counted by the inspection timer 422 reaches the second notification period [Td], the notification circuit 43 performs the second notification with light.

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

On the other hand, the inspection timer 422 resets the measured value of the non-inspection period Tb when the battery 3 is inspected before the non-inspection period Tb reaches the second notification period [Td]. In other words, if the battery 3 is not inspected before the non-inspection period Tb reaches the second notification period [Td], the inspection timer 422 continues to count the non-inspection period Tb. When done, the inspection timer 422 resets the counted value of the non-inspection period Tb.

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

First, in the lighting device 4, when the control circuit 42 starts to supply emergency power, the control circuit 42 assumes that the charging of the battery 3 has started, and the power source timer 421 starts measuring the usage period Ta ( time t0). When the power supply timer 421 starts counting the usage period Ta, the counted value of the usage period Ta increases from zero with the passage of time.

After that, when the usage 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 inspection E1 of the battery 3 (time t2). When the inspection E1 is completed, the inspection timer 422 starts timing the non-inspection period Tb (time t3). The notification circuit 43 performs the second notification N2 when the non-inspection period Tb reaches the second notification period [Td] (time t4). When the second notification N2 is performed, the inspector performs inspection E2 (time t5). When the inspection E2 is completed, the inspection timer 422 is reset, and the inspection timer 422 starts counting the non-inspection period Tb (time t6). Then, if the replacement process of the battery 3 is not executed, the non-inspection 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 inspection E2. When the inspection E2 is completed, the inspection timer 422 is reset, and the inspection timer 422 starts counting the non-inspection period Tb.

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

That is, even if the lighting device 4 is not inspected by an inspector, the usage period Ta of the battery 3 is the first notification period [Tc] (for example, three years or five years determined by law). , 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.

Further, 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 clocking of the usage period Ta is started until the first notification N1 is performed. Then, if the battery 3 is not replaced after the first inspection, the lighting device 4 makes a second notification N2. Therefore, the lighting device 4 can prompt the inspection at an appropriate time in consideration of the life of the battery 3 and the like. In addition, the control circuit 42 acquires the current time from the real-time clock, and according to a predetermined schedule, during a time zone that can be notified (for example, a time zone when people are present in the building where the disaster prevention lighting equipment 1 is installed) It is preferable to cause the notification operation to be executed.

In this case, the notification control circuit 423 notifies by changing the lighting state of the light source 2 . For example, the notification control circuit 423 periodically changes the light intensity of the light source 2, periodically changes the light color of the light source 2, or causes the light source 2 to blink. Note that the notification unit may perform the first notification using the light source 2 and the second notification using the display element. Alternatively, the notification unit may perform the first notification using the display element and 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 with light using the light source 2 .

In addition, when performing at least one of the first notification and the second notification, the notification unit first dims the light source 2 (or blinks) with a light amount lower or higher than the emergency lighting, and a constant from the start of lighting. After the elapse of time, the light source 2 may be lit (or blinked) with the same amount of light as emergency lighting. Alternatively, the notification unit may gradually increase the light intensity 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 lights (or blinks) the display element 431, and after a certain period of time has elapsed from the start of lighting of the display element 431, the light source 2 may be lit (or blinking). The dimming level at the time of dimming lighting is a dimming level less than 100% or a dimming level exceeding 100%.

As a modification 6 of the present embodiment, the notification unit of the lighting device 4 may perform the first notification and the second notification with light using at least one of the plurality of light emitting elements of the light source 2 . Light source 2 includes a plurality of light emitting elements. Note that the notification unit may perform the first notification using at least one of the plurality of light emitting elements, and may perform the second notification using the display element. Alternatively, the notification unit may perform the first notification using the display element and 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 with light using a plurality of light emitting elements of the light source 2 .

As a modification 7 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 modified 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, the notification circuit 43 performs the first notification when a person is present when the use period Ta reaches the first notification period [Tc]. In this case, the notification control circuit 423 of the control circuit 42 acquires the detection result from the human sensor that detects the presence of a person when the usage period Ta reaches the first notification period [Tc]. Then, when a person is present, the notification control circuit 423 controls the notification circuit 43 to perform the first notification. The notification circuit 43 performs the first notification under the control of the notification control circuit 423 . On the other hand, even if the period of use Ta reaches the first notification period [Tc], the notification circuit 43 does not perform the first notification when there is no person present. That is, the notification circuit 43 performs the first notification when a person is present after the usage 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, the notification circuit 43 performs the second notification when the non-inspection period Tb reaches the second notification period [Td] and the person is present. In this case, the notification control circuit 423 acquires the detection result from the human sensor that detects the presence of a person when the non-inspection period Tb reaches the second notification period [Td]. Then, when a person is present, the notification control circuit 423 controls the notification circuit 43 to perform the second notification. The notification circuit 43 performs the second notification under the control of the notification control circuit 423 . On the other hand, even if the non-inspection period Tb has reached the second notification period [Td], the notification circuit 43 does not perform the second notification when there is no person present. That is, the notification circuit 43 performs the second notification when a person is present after the non-inspection period Tb reaches the second notification period [Td].

As a ninth modification of the present embodiment, the notification circuit 43 may perform the first notification at a predetermined first timing. More specifically, in the first function, the notification circuit 43 performs the first notification at a predetermined first timing when the period of use Ta reaches the first notification period [Tc]. The first timing is the time or time zone in which the first notification is possible. For example, the first timing is the time or time zone when people are in the building where the disaster prevention lighting equipment 1 is installed. In Modified Example 9, the control circuit 42 stores in advance a schedule including the first timing. When the period of use 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. Controls circuit 43 . 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, if the first timing is 10:00 am and the use period Ta reaches the first notification period [Tc], the notification circuit 43 makes the first notification at 10:00 am. In other words, even if the usage 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 the time period from 7:00 pm to 9:00 pm (2 hours), when the usage period Ta reaches the first notification period [Tc], the notification circuit 43 The first notification is made in the time zone from 1:00 to 9:00 pm. In other words, the notification circuit 43 does not perform the first notification in a time zone other than the time zone from 7:00 pm to 9:00 pm.

Similarly, the notification circuit 43 may perform the second notification at a predetermined second timing. More specifically, in the second function, the notification circuit 43 performs the second notification at a predetermined second timing when the non-inspection period Tb reaches the second notification period [Td]. The second timing is, for example, time or time period. As an example, if the second timing is 3:00 pm, and the non-inspection period Tb reaches the second notification period [Td], the notification circuit 43 makes the second notification at 3:00 pm. In other words, even if the non-inspection 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 the time zone (4 hours) from 6:00 pm to 10:00 pm, when the non-inspection period Tb reaches the second notification period [Td], the notification circuit 43 The second notification is performed in the time zone from 6:00 to 10:00 pm. In other words, the notification circuit 43 does not perform the second notification in a time zone other than the time zone from 6:00 pm to 10:00 pm.

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

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

As a modified example 11 of the present embodiment, the power timer 421 may continue timing until the usage period Ta reaches the life of the battery 3 instead of until the usage period Ta reaches the first notification period [Tc]. (See phantom lines in Figure 2). More specifically, the power timer 421 continues clocking without resetting the clock value when the usage period Ta reaches the first notification period [Tc]. Then, when the period of use Ta has reached the end of its life, the notification control circuit 423 controls the notification circuit 43 so as to issue a notification to prompt replacement of the battery 3 . The notification circuit 43 performs the above notification under the control of the notification control circuit 423 . When the usage period Ta reaches the life period, the power timer 421 resets the counted value. After that, when the replacement process of the battery 3 is completed, the power source timer 421 newly starts timing the usage period Ta.

Further, in the inspection of an emergency power supply such as the battery 3, if the battery 3 cannot maintain discharge for a specified time, the notification control circuit 423 causes the notification unit to perform notification to prompt replacement of the battery 3. may be controlled. The notification circuit 43 performs the above notification under the control of the notification control circuit 423 .

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

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

Then, each of the plurality of lighting devices 4 that can communicate via the communication line 8 communicates with other lighting devices 4 other than the own device, thereby issuing the first notification and the second notification to the other disaster prevention lighting system B2. conduct.

For example, each control circuit 42 of a plurality of lighting devices 4 controls a communication circuit to transmit data related to notification of inspection time to other lighting devices 4 when the usage period reaches the notification period. Likewise, when the non-inspection period reaches the second notification period, each control circuit 42 also transmits data related to notification to the other lighting devices 4 at the time of inspection to the other lighting devices 4 . In the other 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 in the own device but also in other disaster prevention lighting fixtures 1 .

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

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

Also, the communication circuit may transmit and receive signals by wireless communication. For example, the communication circuit may transmit signals in compliance with standards such as wireless LAN, BLUETOOTH (registered trademark), or ZIGBEE (registered trademark) (for example, IEEE 802.11, IEEE 802.15.1, IEEE 802.15.4, etc.). and receive signals. In this case, the communication line 8 becomes unnecessary 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 its own device.
