Description

[Technical field]

[0001] The present disclosure relates to emergency lighting devices such as emergency exit lights or emergency lighting devices, and lighting control systems. [Background technology]

[0002] An emergency lighting device charges a storage battery from an external power source, and in an emergency where the external power source is cut off, such as a power outage, the storage battery turns on the light source. The emergency lighting device is provided with a function for checking the storage battery by checking whether the storage battery can turn on the light source for a predetermined period of time. This makes it possible to confirm that the emergency lighting device can be used in an emergency.

[0003] In the emergency lighting device of Patent Document 1, after the storage battery is electrically connected during installation, the storage battery is continuously charged for a predetermined time and the device is placed in an inspection restriction mode in which inspection is restricted. Even in the inspection restriction mode, the lighting by the storage battery can be confirmed by canceling the inspection restriction mode. This makes it possible to confirm that there are no problems with lighting by the storage battery immediately after installing the emergency lighting device or replacing the storage battery.

[0004] [Patent Document 1] JP 2008-135212 A Summary of the Invention [Problem to be solved by the invention]

[0005] However, during inspection, the storage battery is in a discharged state. Therefore, in a situation where a power outage occurs and the storage battery is likely to be used, such as a disaster, it is desirable not to inspect the storage battery, since there is a concern that the light source cannot be turned on for a predetermined period of time after the power outage occurs. However, with the above method, there is a problem that inspection is performed if the inspection restriction mode is released even in a situation where a power outage is likely to occur.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0012] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present disclosure will be described with reference to the drawings. The same or corresponding components are designated by the same reference numerals, and repeated description may be omitted.

[0013] First embodiment Fig. 1 is a perspective view of an emergency lighting device 100 according to a first embodiment of the present disclosure. Fig. 2 is an exploded view of the emergency lighting device 100 according to the first embodiment of the present disclosure.

[0014] The emergency lighting device 100 is attached to a mounting portion such as a ceiling or a wall. The emergency lighting device 100 is, for example, an emergency light or an emergency lighting device. In the case of an emergency light, the Fire Service Act of Japan requires that the light source 2 be continuously lit for 20 minutes or 60 minutes by the storage battery 4. On the other hand, in the case of an emergency lighting device, the Building Standards Act of Japan requires that the light source 2 be continuously lit for 30 minutes or 60 minutes by the storage battery 4.

[0015] The emergency lighting fixture 100 includes a fixture body 1, a light source 2, a lighting device 3, and a storage battery 4.

[0016] <Apparatus body 1> The fixture body 1 is a housing formed in a cylindrical shape, and houses the light source 2, the lighting device 3, the storage battery 4, etc. Note that the shape of the fixture body 1 is not limited to a cylindrical shape as long as it can house the light source 2, the lighting device 3, and the storage battery 4.

[0017] <Light source 2> The light source 2 has a light source unit 21 and a light distribution control member 22. The light source unit 21 is a light emitting element such as an LED (Light Emitting Diode) that lights up when power is supplied. The light source unit 21 is not limited to an LED, and may be a laser element, an organic EL, or the like. The light distribution control member 22 is, for example, a lens. The light distribution control member 22 is disposed so as to cover the light source unit 21, and controls the light distribution of the light emitted from the light source unit 21.

[0018] <Lighting device 3> The lighting device 3 controls the lighting of the light source 2 and the charging / discharging and inspection of the storage battery 4. The lighting device 3 receives information on a state in which there is a possibility of a power outage (hereinafter referred to as power outage possibility information), and restricts the inspection of the storage battery 4 when it determines that it is necessary to restrict the inspection.

[0019] Specifically, power outage concern information is weather warnings such as heavy rain, heavy snow, strong winds, and floods. It is also disaster-related information such as evacuation orders or evacuation recommendations, as typified by L-Alert. Or it is information such as ballistic missile information, emergency earthquake alerts, or large tsunami warnings, as typified by the nationwide instantaneous warning system (J-Alert), which transmits information on time-sensitive situations. Power outage concern information may be information other than the above, as long as it notifies users that there is a concern about a power outage.

[0020] <Battery 4> The storage battery 4 is a rechargeable battery. The storage battery 4 is, for example, a secondary battery such as a nickel-cadmium battery, a nickel-metal hydride battery, or a lithium-ion battery, or an all-solid-state battery. The storage battery 4 is charged with power from the external power source 1000 during normal times when the external power source 1000 is supplied. On the other hand, during an emergency when the external power source 1000 is cut off, the storage battery 4 supplies power to the light source 2 via the lighting device 3.

[0021] 3 is a block diagram showing the configuration of the emergency lighting device 100 according to the first embodiment of the present disclosure. The light source 2 and the storage battery 4 are as described above, and therefore will not be described here. The lighting device 3 will be described in detail below.

[0022] <Inspection switch 5> The inspection switch 5 is a switch that an operator presses when inspecting the storage battery 4. The inspection switch 5 is a push button switch attached to the lighting device 3, and is positioned so that the part that is pressed is exposed from an opening provided in the fixture body 1. This allows an operator to press the inspection switch 5 from outside the fixture body 1.

[0023] <Receiving unit 6> The receiving unit 6 receives an infrared signal from the remote control. The infrared signal includes an inspection command that instructs the inspection unit 343 to start inspection. Furthermore, the infrared signal includes the above-mentioned power outage concern information. The receiving unit 6 is attached to the lighting device 3 and is arranged so as to be exposed from an opening provided in the fixture body 1.

[0024] <Transmitter 7> The transmitter 7 transmits an infrared signal to an external terminal or controller. The transmitted content is, for example, the inspection result of the storage battery 4, but is not limited to this.

[0025] The signals transmitted and received by the receiver 6 and the transmitter 7 are not limited to infrared signals, and may be wireless signals as long as they can transmit and receive the above-mentioned inspection command, power outage concern information, and inspection results. Furthermore, the transmission and reception of signals does not have to be wireless, and may be wired.

[0026] Monitor 8 The monitor 8 is equipped with LEDs as indicator lights, each of which shows a different light color. For example, the red monitor indicates the status of the light source 2, and when it is lit, it indicates that the light source 2 is abnormal. The green monitor indicates the status of the storage battery 4, and when it is lit, it indicates that the storage battery 4 is normal. On the other hand, when the green monitor is flashing, it indicates that the storage battery 4 has reached the end of its life. Also, when the green monitor is off, it indicates that the connection status of the storage battery 4 is abnormal. The orange monitor indicates the inspection status of the emergency lighting device 100, and when it is flashing, it indicates that the emergency lighting device 100 is undergoing inspection.

[0027] The color, lighting state, and display content of the indicator lamp are not limited to those described above. Furthermore, the monitor 8 is not limited to one that indicates the state of the emergency lighting device 100 by the lighting state of the LED, but may have a screen that displays the state of the emergency lighting device 100, or may notify the state by voice.

[0028] The lighting device 3 includes a power supply circuit 31, a charging circuit 32, a lighting circuit 33, and a control device .

[0029] <Power circuit 31> The power supply circuit 31 converts AC power supplied from an external power supply 1000 such as a commercial power supply into DC power. The power supply circuit 31 supplies the converted DC power to the charging circuit 32 and the control device .

[0030] <Charging circuit 32> The charging circuit 32 charges the storage battery 4 with power supplied from the external power source 1000 and converted into DC power by the power supply circuit. Since the power of a secondary battery such as the storage battery 4 gradually decreases over time due to self-discharge, the charging circuit 32 performs trickle charging to continuously supply weak power to the storage battery 4. Note that the charging method is not limited to trickle charging, and a method such as quick charging that quickly charges the storage battery 4 with power greater than that of trickle charging may also be used.

[0031] <Lighting circuit 33> The lighting circuit 33 discharges the storage battery 4 under the control of the control device 34 and lights up the light source 2 with the power from the storage battery 4 .

[0032] <Control device 34> The control device 34 is, for example, a microcomputer. The control device 34 includes a control unit 341, a detection unit 342, an inspection unit 343, a timer unit 344, a storage unit 345, and a determination unit 346.

[0033] <Control unit 341> When the detection unit 342 detects that the power from the external power source 1000 has been cut off, the control unit 341 stops the supply of power from the charging circuit 32 to the storage battery 4. The control unit 341 further supplies power from the storage battery 4 to the light source 2 via the lighting circuit 33 to light the light source 2. When the lighting of the light source 2 causes the voltage of the storage battery 4 to fall below a predetermined voltage, the control unit 341 stops the supply of power from the storage battery 4 to the light source 2. On the other hand, when it is determined that the power supply from the external power source 1000 has been restored and is again possible, the control unit 341 causes the charging circuit 32 to charge the storage battery 4.

[0034] <Detection unit 342> The detection unit 342 detects that the power from the external power source 1000 has been cut off.

[0035] <Inspection Department 343> The inspection unit 343 inspects the storage battery 4 when triggered by pressing the inspection switch 5 or when the receiving unit 6 receives an infrared signal including an inspection command. With the start of inspection, the inspection unit 343 causes the timer unit 344, which will be described later, to start timing. Next, the inspection unit 343 stops charging the storage battery 4 by the charging circuit 32. Furthermore, the inspection unit 343 supplies power from the storage battery 4 to the light source 2 via the lighting circuit 33 to light the light source 2. The inspection unit 343 measures the voltage of the storage battery 4, and inspects whether the voltage exceeds the discharge reference voltage for a specified lighting time required by laws and regulations.

[0036] The trigger for starting the inspection is not limited to pressing the inspection switch 5 or receiving an inspection command at the receiving unit 6. The inspection may be triggered by the time counted by the timing unit 344 reaching a predetermined time. This makes it possible to perform the inspection periodically and automatically.

[0037] When the inspection is completed, the inspection unit 343 stops the supply of power from the storage battery 4 to the light source 2 by the lighting circuit 33. Furthermore, the inspection unit 343 charges the storage battery 4 with the external power source 1000 via the charging circuit 32. Furthermore, the inspection unit 343 displays the inspection result on the monitor 8. Alternatively, the inspection unit 343 transmits the inspection result to an external terminal or controller by the transmission unit 7.

[0038] <Timekeeping section 344> The timer unit 344 measures the time during which the light source 2 is turned on by the power supplied from the storage battery 4. Note that the timer unit 344 may measure the time since the storage battery 4 was mounted in the device body 1.

[0039] <Storage section 345> The storage unit 345 is, for example, a memory having a storage area such as a volatile memory or a non-volatile memory. The storage unit 345 stores a list in which inspection restriction information, which is information about a situation in which inspection of the storage battery 4 should be restricted, is described.

[0040] <Determination unit 346> The determination unit 346 executes a process (hereinafter referred to as a determination process) of comparing the power outage concern information received by the receiving unit 6 with the list stored in the storage unit 345 and determining whether or not the received power outage concern information is inspection restriction information that should restrict inspection of the storage battery 4. The determination process makes it possible to closely examine the power outage concern information received by the receiving unit 6 and implement inspection restrictions only when necessary.

[0041] For example, it is known that weather-related warnings have stages such as warning and special warning, but only the special weather warning may be stored as inspection restriction information in the storage unit 345. In this case, even if the receiving unit 6 acquires weather-related power outage concern information, it is possible to control so that inspection is not restricted when the information is at the warning stage, but is restricted only when the information is at the special warning stage.

[0042] Furthermore, with regard to the disaster-related information, only information related to the area in which the emergency lighting device 100 is installed may be used as the inspection restriction information. In this case, it is possible to perform control such that inspection is restricted only when the receiving unit 6 receives disaster-related information that is particularly relevant to a specific area. Note that the inspection restriction information is not limited to these examples.

[0043] When the power outage concern information received by the receiving unit 6 is recognized as inspection restriction information, the determining unit 346 executes a process (referred to as an inspection restriction process) for putting the inspection unit 343 into an inspection restriction mode. The inspection restriction mode is a mode in which inspection is not started even if a trigger for starting inspection is recognized. For example, the inspection restriction mode is realized by blocking a circuit or signal that notifies the inspection unit 343 that the inspection switch 5 has been pressed or that an inspection command has been received by the receiving unit 6, thereby preventing the start of inspection.

[0044] On the other hand, if the power outage concern information does not match the inspection restriction information stored in the storage unit 345 in the determination process, the determination unit 346 sets the inspection unit 343 to an inspection mode. The inspection mode is a mode in which inspection is started upon recognition of a trigger for starting inspection.

[0045] 4 is a flowchart showing a process executed by the emergency lighting device 100 according to the first embodiment of the present disclosure. First, the process is started. At the start of the process, the inspection unit 343 is in the inspection mode, but inspection is not being performed, and the storage battery 4 is in a charged state.

[0046] Next, the determination unit 346 of the control device 34 causes the receiving unit 6 to acquire power outage concern information (step S101).

[0047] Next, the determination unit 346 executes the above-mentioned determination process to determine whether the power outage concern information received by the receiving unit 6 is inspection restriction information or not (step S102). If it is determined to be inspection restriction information, the determination unit 346 executes the inspection restriction process and sets the inspection unit 343 to inspection restriction mode (step S103). At this time, the user may be notified that the power outage concern information received by the receiving unit 6 is inspection restriction information. Specifically, a conceivable method is to light up an LED built into the monitor 8 or display it on the screen. On the other hand, if it is not determined to be inspection restriction information, the process returns to step S101.

[0048] Next, the determination unit 346 causes the receiving unit 6 to acquire the power outage concern information again (step S104). Furthermore, the determination unit 346 executes the determination process again (step S105). If the information received by the receiving unit 6 does not match the inspection restriction information, this means that the power outage concern information determined to be the inspection restriction information in step S102 has been lifted. Therefore, the determination unit 346 releases the inspection restriction mode and sets the inspection unit 343 to the inspection mode (step S106). This allows the inspection unit 343 to return to the inspection mode again.

[0049] On the other hand, if the information received by the receiving unit 6 in step S105 matches the inspection restriction information, this means that the power outage concern information determined to be the inspection restriction information has not been lifted, or a new warning or the like that requires inspection to be restricted has been issued. In this case, the process returns to step S104, and the inspection restriction mode is maintained.

[0050] <Variation 1 of Fig. 4> In the above description, it is assumed that inspection is not being performed and the storage battery 4 is in a charged state at the start of the inspection. On the other hand, if inspection is being performed at the start of the inspection, when the power outage concern information received by the receiving unit 6 is determined to be inspection restriction information in the determination process of step S102, the determination unit 346 stops the inspection being performed. Furthermore, the determination unit 346 operates the charging circuit 32 to charge the storage battery 4 from the external power source 1000. At that time, it is desirable to rapidly charge the storage battery 4.

[0051] By executing the above-described process, it is possible to restore the storage battery 4 to a fully charged state even if power outage concern information is received during inspection.

[0052] It is preferable that the user is notified by the transmission unit 7 or the monitor 8 that the determination unit 346 has stopped the inspection. This allows the user to know that the inspection was not completed and to carry out the inspection again.

[0053] <Variation 2 of Fig. 4> In step S106, it has been described that the determination unit 346 cancels the inspection restriction mode when the power outage concern information received by the receiving unit 6 does not match the inspection restriction information. However, the condition for canceling the inspection restriction mode is not limited to this. For example, restriction release information, which is information about a situation in which the inspection restriction mode should be released, may be stored in the storage unit 345, and when the information received by the receiving unit 6 matches the restriction release information, the determination unit 346 may release the inspection restriction mode. Note that the restriction release information is information about releasing an alarm, but is not limited to this.

[0054] As described above, in the emergency lighting device 100 of the present disclosure, when the received power outage concern information is determined to be inspection restriction information, the inspection unit 343 is set to the inspection restriction mode. This makes it possible to provide an emergency lighting device that can restrict the inspection of the storage battery in a situation where a power outage is likely to occur. This makes it possible to maintain the storage battery 4 in a charged state in a situation where a power outage is likely to occur.

[0055] First Modification of First Embodiment In the above description, a determination process is performed on the received power outage concern information, and when the power outage concern information is determined to be inspection restriction information, the inspection unit 343 is set to the inspection restriction mode. However, the determination process may not be performed, and the inspection unit 343 may be set to the inspection restriction mode immediately upon receiving the power outage concern information. This allows the inspection unit 343 to immediately switch to the inspection restriction mode when, for example, there is a high degree of agreement between the power outage concern information and the inspection restriction information, by omitting the determination process.

[0056] Second Modification of First Embodiment The condition for the determination unit 346 to set the inspection unit 343 to the inspection restriction mode does not have to be limited to when the power outage concern information received by the receiving unit 6 is recognized as inspection restriction information. The inspection restriction mode may also be entered when the receiving unit 6 receives information, such as an attendance record, indicating that a person is present in the building or room in which the emergency lighting device 100 is installed.

[0057] Third Modification of First Embodiment When the receiver 6 receives a signal from the remote controller to release the inspection restriction mode, the inspection restriction mode may be released even in a situation where a power outage is highly likely to occur. This allows inspection to be performed according to the operator's wishes even in a situation where a power outage is highly likely to occur.

[0058] Fourth Modification of the First Embodiment The determination unit 346 may further include a machine learning unit and a model generation unit. The machine learning unit learns the power outage concern information received by the receiving unit 6 and whether or not a power outage actually occurred due to a disaster or the like indicated by the power outage concern information, and the model generation unit generates inspection restriction information. By overwriting and updating the inspection restriction information stored in the storage unit 345 with the generated inspection restriction information, it is possible to improve the quality of the inspection restriction information that serves as a filter for scrutinizing the power outage concern information.

[0059] Embodiment 2 In this embodiment, a lighting control system 500 including one or more emergency lighting devices 10 will be described. In the following, changes from the first embodiment will be described.

[0060] FIG. 5 is a block diagram showing a configuration of a lighting control system 500 according to the second embodiment of the present disclosure.

[0061] The emergency lighting device 10 differs from the emergency lighting device 100 described in the first embodiment in that the emergency lighting device 10 does not include the storage unit 345 and the determination unit 346.

[0062] The lighting control device 200 communicates with one or more emergency lighting devices 10 via wired or wireless communication, and collectively controls the lighting and inspection of the emergency lighting devices 10. The lighting control device 200 has a memory unit 210, a determination unit 220, a transmission unit 230, and a reception unit 240.

[0063] <Receiving unit 240> The receiving unit 240 forms a wired or wireless network 20 with an external device 300 such as a server or a terminal, and acquires power outage concern information and the like. The receiving unit 240 also acquires information related to lighting and inspection from the emergency lighting device 10. Information related to inspection is, for example, information indicating whether the inspection unit 343 of the emergency lighting device 10 is in an inspection mode or an inspection restriction mode.

[0064] <Storage section 210> The storage unit 210 stores a list in which inspection restriction information is described, similar to the storage unit 345 described in the first embodiment. Note that the inspection restriction information here is information about a situation in which inspection of the storage battery 4 of the emergency lighting device 10 should be restricted.

[0065] <Determination unit 220> The determination unit 220 executes a determination process of comparing the power outage concern information received by the receiving unit 240 with the list stored in the storage unit 210 and determining whether the received power outage concern information is inspection restriction information. If the power outage concern information received by the receiving unit 240 is recognized as inspection restriction information, the determination unit 220 executes a process (referred to as a transmission process) of transmitting a control signal for restricting inspection of the storage battery 4 to the emergency lighting device 10.

[0066] <Transmitter 230> The transmission unit 230 transmits a control signal to the emergency lighting device 10. The control signal is not limited to a signal that restricts inspection of the storage battery 4 of the emergency lighting device 10 (i.e., switches to inspection restriction mode), but may be a signal that controls the lighting state of the light source 2 of the emergency lighting device 10. If the power outage concern information does not match the inspection restriction information stored in the storage unit 210 in the determination process, a signal that switches the emergency lighting device 10 to the inspection mode may be transmitted. The inspection mode is a mode in which the emergency lighting device 10 starts inspection when it recognizes a trigger to start inspection. The transmission unit 230 may transmit information to the external device 300.

[0067] As described above, the lighting control system 500 of the present disclosure includes one or more emergency lighting devices 10 and a lighting control device 200 that controls the emergency lighting devices 10. The lighting control device 200 transmits a control signal for restricting inspection of the storage battery 4 to the emergency lighting devices 10. As a result, an inspection restriction mode for restricting inspection of the storage battery 4 is applied to the emergency lighting devices 10 that have received the control signal. This means that it is no longer necessary to provide the emergency lighting devices 10 with the memory unit 345 and the determination unit 346 described in the first embodiment. Therefore, in the emergency lighting devices 10, the load associated with the processing performed by the memory unit 345 and the determination unit 346 can be eliminated, and the effect of reducing the load can be increased as the number of emergency lighting devices 10 increases.

[0068] <Modification of the second embodiment> In the above description, a determination process is performed on the received power outage concern information, and if the power outage concern information is determined to be inspection restriction information, a control signal for restricting inspection of the storage battery 4 is transmitted to the emergency lighting device 10. However, the control signal may be transmitted immediately upon receiving the power outage concern information without performing the determination process. In this way, if there is a high degree of match between the power outage concern information and the inspection restriction information, the determination process can be omitted and the emergency lighting device 10 can be immediately switched to the inspection restriction mode.

[0069] Third embodiment In this embodiment, the lighting control device 200 of the second embodiment further includes an inspection management unit 250. In the following, changes from the second embodiment will be described.

[0070] 6 is a block diagram showing a configuration of a lighting control system 600 according to a third embodiment of the present disclosure. The inspection management unit 250 of the lighting control device 200 stores inspection schedules for one or more emergency lighting devices 10. When there are multiple emergency lighting devices 10 to be managed, the inspection management unit 250 stores an inspection start date and time for each of the emergency lighting devices 10. When a predetermined inspection start date and time arrives, the inspection management unit 250 transmits an inspection start signal via the transmission unit 230 to start inspection of the target emergency lighting device 10.

[0071] The determination unit 220 executes the same determination process as in embodiment 2. When the power outage concern information received by the receiving unit 240 is determined to be inspection restriction information, the determination unit 220 suppresses the transmission of an inspection start signal from the transmitting unit 230 to the emergency lighting device 10. This makes it possible to control so that inspection of the emergency lighting device 10 is not performed even if the inspection start date and time arrives in a situation where there is a high possibility of a power outage.

[0072] Furthermore, the determination unit 220 notifies the inspection management unit 250 that the inspection start signal has been suppressed. This allows the inspection management unit 250 to know that the inspection of the emergency lighting device 10 has not been performed as scheduled.

[0073] If a specified inspection start date and time arrives during a period in which the determination unit 220 is suppressing the inspection start signal, and the inspection of the emergency lighting device 10 has not been carried out as scheduled, the inspection management unit 250 notifies the external device 300 of that effect, or causes the monitor 8 of the target emergency lighting device 10 to display the fact that the inspection has not been carried out as scheduled.

[0074] It is preferable to wait until the inhibition of the inspection start signal by the determination unit 220 is released, and then have the inspection management unit 250 set a new inspection start date for the target emergency lighting device 10.

[0075] As described above, in the lighting control system 600 of this embodiment, the inspection management unit 250 of the lighting control device 200 stores the inspection schedule for the emergency lighting device 10. When the power outage concern information received by the receiving unit 240 is recognized as inspection restriction information, the lighting control device 200 suppresses the transmission of an inspection start signal to the target emergency lighting device 10. This allows inspection of the emergency lighting device 10 to be carried out as scheduled under normal circumstances, while preventing the start of inspection in situations where there is a high possibility of a power outage occurring.

[0076] <Modification of the Third Embodiment> If inspection of the emergency lighting device 10 has already begun at the time when the power outage concern information received by the receiving unit 240 is recognized as inspection restriction information, the determining unit 220 may transmit an inspection stop signal to the emergency lighting device 10 to stop the inspection. This makes it possible to prevent the inspection of the storage battery 4 from being stopped in the emergency lighting device 10 that has received the inspection stop signal, and to prevent the consumption of the charged power.
