Summary of the Invention

Problems to be Solved by the Invention

[0004] However, since a conventional emergency lamp always lights at a constant illuminance, although it is less likely to be a major problem in the case of a short power outage, in the case of a large-scale power outage lasting for a long time or a power outage during a disaster, there is a problem that the lighting time of the emergency lamp is insufficient compared to the time until power restoration or the time required for evacuation preparation. In addition, as the user spends a long time under the emergency lamp, the user's eyes get used to it, and even though sufficient visibility can be ensured at an illuminance lower than the illuminance when the emergency lamp is lit, the emergency lamp continues to light at a constant illuminance, resulting in a problem of wasting the battery.

Also, the drawings are schematic diagrams that have been appropriately emphasized, omitted, or adjusted in ratio to show the present invention, and may be different from the actual shape, positional relationship, and ratio.

[0016] [Description of Configuration] First, referring to FIG. 1, the power failure lighting system 1 according to the embodiment of the present invention will be outlined. The power failure lighting system 1 according to the present embodiment is attached to an arbitrary space in a building and includes lighting fixtures 100 to 107 configured to be communicable with each other, a power failure detection device 10 connected to the indoor wiring and capable of detecting a power failure, and an operation terminal 200 capable of operating the lighting fixtures 100 to 107. The power failure detection device 10 is configured to be able to output a power failure detection signal to the lighting fixtures 100 to 107 when detecting a power failure. Further, the lighting fixtures 100 to 107 further have a function as an embedded emergency light.

[0017] [Configuration of Power Failure Detection Device] The power outage detection device 10 generally includes, as shown in FIG. 2, a plug 20 that is inserted into a power outlet to receive power supply, a power outage detection unit 30, an emergency power source 40 that supplies power to the power outage detection device 10 during a power outage, a main control unit 50, and a communication unit 60 that can transmit a power outage detection signal to lighting fixtures 100 to 107.

[0021] The power outage detection device 10 having such a configuration waits while receiving power supply from the indoor wiring during normal times, and is configured to be powered from the emergency power supply 40 when the power supply from the indoor wiring is cut off during a power outage. Therefore, it is possible to transmit a power outage detection signal to the emergency communication units 180 of the lighting fixtures 100 to 107 described later even during a power outage.

[0022] [Configuration of Lighting Fixture] The lighting fixtures 100 to 107 generally include, as shown in FIG. 3, a power supply 110, a light emitting unit 130 capable of adjusting the lighting state, a main control unit 120 capable of controlling the lighting state of the light emitting unit 130, and a communication unit 140. With these configurations, a lighting fixture that can be used during normal times is constituted. Hereinafter, in this specification, "control of the lighting state" means controlling various lighting states of the light emitting unit, and includes, for example, various controls such as on / off control for switching the on / off of the light emitting unit and dimming control for changing the dimming (illuminance) of the light emitting unit.

[0023] In addition, the lighting fixtures 100 to 107 include an emergency power supply 150, an emergency light emitting unit 170 capable of adjusting the lighting state, an emergency control unit 160 capable of controlling the lighting state of the emergency light emitting unit 170, and an emergency communication unit 180. With these configurations, an emergency light that can be used during a power outage is constituted. In other words, the lighting fixtures 100 to 107 according to the present embodiment are lighting devices with emergency lights. The configuration related to the emergency light may be an in-built type configuration pre-incorporated in the lighting fixtures 100 to 107, or may be a configuration of a unit that can be retrofitted to existing lighting fixtures without emergency lights.

[0024] The light emitting unit 130 and the emergency light emitting unit 170 have a dimming function, and the light emitting unit 130 further has a color adjustment function. In addition, the main control unit 120 includes a lighting control unit 122, a dimming control unit 124, a color adjustment control unit 126, and a light-off reservation unit 128 for setting a light-off reservation. The lighting control unit 122 is configured to be able to control the lighting and light-off of the light emitting unit 130. The dimming control unit 124 is configured to be able to control the illuminance of the light emitting unit 130, and the color adjustment control unit 126 is configured to be able to control the color temperature of the light emitting unit 130.

[0025] The communication unit 140 is configured to be communicable with the communication units 140 of other lighting fixtures and the communication unit 230 of the operation terminal 200 described later. Specifically, the communication unit 140 is configured to be able to receive operation signals transmitted from the communication unit 230 of the operation terminal 200 described later and the communication units 140 of other lighting fixtures, and is configured to be able to transmit the received operation signals to the communication units 140 of other lighting fixtures.

[0026] The emergency power source 150 includes a battery. When the lighting fixtures 100 to 107 are lit as normal lighting fixtures, the battery is charged from the power supply of the indoor wiring. When the power supply from the indoor wiring to the lighting fixtures 100 to 107 is cut off, the emergency power source 150 is configured to supply power to the emergency control unit 160, the emergency light emitting unit 170, and the emergency communication unit 180.

[0027] The emergency control unit 160 includes a lighting control unit 162, a dimming control unit 164, a remaining amount calculation unit 166, and a relay lighting control unit 168. The lighting control unit 162 is configured to be able to control the lighting and extinguishing of the emergency light emitting unit 170. The dimming control unit 164 is configured to be able to control the illuminance of the emergency light emitting unit 170. The remaining amount calculation unit 166 monitors the remaining battery amount of the emergency power source 150 and is configured to calculate the remaining continuous lighting time based on the remaining battery amount and the lighting state of the emergency light emitting unit 170.

[0028] The relay lighting control unit 168 is configured to be able to generate a relay lighting signal transmitted from the emergency communication unit 180 to other lighting fixtures. Lighting fixtures 100 to 107 having such a configuration, for example, when receiving a power outage detection signal from the power outage detection device 10, only turn on an arbitrary lighting fixture as an emergency light, and before the battery provided in the emergency power supply 150 of the lit lighting fixture runs out, by transmitting a relay lighting signal to other lighting fixtures, it becomes possible to turn on the next lighting fixture as an emergency light in a relay manner. Specifically, it is possible to sequentially turn on the emergency lights installed in the living room, corridor, and entrance along the evacuation route, or when there are lighting fixtures installed adjacent to each other within a predetermined range, only turn on one of them, and switch to only turning on the other emergency light before the battery provided in the emergency power supply 150 runs out.

[0029] The emergency communication unit 180 is configured to be communicable with the communication unit 60 of the power outage detection device 10, the emergency communication units 180 of other lighting fixtures, and the communication unit 230 of the operation terminal 200 described later. Specifically, the emergency communication unit 180 is configured to be able to receive a power outage detection signal and a restoration detection signal transmitted from the communication unit 60 of the power outage detection device 10, and is configured to be able to transmit and receive the power outage detection signal and the restoration detection signal with the emergency communication units 180 of other lighting fixtures. Also, the emergency communication unit 180 is configured to be able to receive an operation signal transmitted from the communication unit 230 of the operation terminal 200 described later. Further, the emergency communication unit 180 is configured to be able to transmit the remaining power information of the emergency light to the communication unit 230 of the operation terminal 200 described later. The remaining power information transmitted from the emergency communication unit 180 includes the battery remaining amount of the emergency power supply 150 and the lighting duration which is the calculation result of the remaining amount calculation unit 166.

[0030] When lighting fixtures 100 to 107 having the above configuration receive a power outage detection signal from the power outage detection device 10, the lighting control unit 162 of the emergency control unit 160 turns on the emergency light emitting unit 170, and when receiving a restoration detection signal from the power outage detection device 10, the lighting control unit 162 of the emergency control unit 160 turns off the emergency light emitting unit 170.

[0031] In addition, the lighting fixtures 100 to 107 are configured to be able to construct a mesh-type network, and can transmit a power outage detection signal to lighting fixtures installed outside the communication range of the power outage detection device 10 via other lighting fixtures installed within the communication range.

[0032] [Configuration of the operation terminal] The operation terminal 200 generally includes a main control unit 210, a display unit 220, and a communication unit 230 as shown in FIG. 4. As the operation terminal 200, a portable device such as a smartphone, a tablet terminal, or a notebook computer having portability is preferable, but it is not limited thereto. When the operation terminal 200 is portable, it is possible to operate the emergency light while moving while holding the operation terminal 200, and it is possible to evacuate more safely in the event of a disaster. On the other hand, when the operation terminal 200 is a stationary type, since the location of the operation terminal 200 can always be grasped, it is possible to approach the operation terminal 200 promptly after a power outage occurs.

[0033] As shown in FIG. 4, the main control unit 210 includes a lighting operation instruction unit 212, a dimming operation unit 214, and a lighting sequence operation unit 216. Further, the main control unit 210 further includes a color adjustment operation unit (not shown) capable of instructing the color adjustment operation of the light emitting unit 130 provided in the lighting fixtures 100 to 107 and a turn-off reservation unit (not shown) capable of setting a turn-off reservation for the light emitting unit 130. The lighting operation instruction unit 212 is configured to be able to instruct the lighting operation and the turn-off operation of the light emitting unit 130 and the emergency light emitting unit 170 provided in the lighting fixtures 100 to 107. The dimming operation unit 214 is configured to be able to instruct the dimming operation of the light emitting unit 130 and the emergency light emitting unit 170 provided in the lighting fixtures 100 to 107.

[0034] The lighting sequence operation unit 216 is configured to be able to set the lighting sequence of the emergency light emitting units 170 provided in the lighting fixtures 100 to 107. For example, by operating the lighting sequence operation unit 216 and setting the lighting sequence, the user can turn on only an arbitrary lighting fixture without turning on all the emergency light emitting units 170 of the lighting fixtures 100 to 107 during a power outage, and can turn on the next emergency light before the battery level of the emergency power source 150 runs out or after a predetermined time has elapsed.

[0035] The main control unit 210 having such a configuration is configured to be able to generate an operation signal transmitted from the communication unit 230 to the lighting fixtures 100 to 107. The operation signal includes one or more instructions selected from the operation instruction of the lighting operation instruction unit 212, the operation instruction of the dimming operation unit 214, the operation instruction of the lighting sequence operation unit 216, the operation instruction of a color tone adjustment operation unit (not shown), and the operation instruction of a light-off reservation unit (not shown).

[0036] As shown in FIG. 5, the display unit 220 includes display areas 220a to 220d, and the display areas 220a to 220d each include a dimming area 222, a brightness display area 224, a lighting ON / OFF button 226, and a battery display area 228.

[0037] The display areas 220a to 220d are graphical user interfaces capable of operating the illumination states of the emergency light-emitting units 170 included in the lighting fixtures 100 to 107. The operation terminal 200 is configured such that when the user operates the display areas 220a to 220d of the display unit 220, the main control unit 210 generates an operation signal according to the operation content of the user, and the communication unit 230 transmits the operation signal.

[0038] The display area 220a is configured to be able to collectively operate the illumination states of the emergency light-emitting units 170 included in the lighting fixtures 100 to 107, and the display areas 220b to 220d are each configured to be able to individually operate the illumination states of the emergency light-emitting units 170 included in the lighting fixtures 100 to 102.

[0039] The dimming area 222 enables dimming operation of the emergency light-emitting units 170 included in the lighting fixtures 100 to 107, and the illuminance of the emergency light-emitting units 170 is displayed in the brightness display area 224 according to the dimming state. The display in the brightness display area 224 may be a relative value [%] with respect to the brightest state or an absolute value [lx, lm] of the illuminance.

[0040] The lighting ON / OFF button 226 can perform the lighting and extinguishing operations of the emergency light-emitting unit 170 provided in the lighting fixtures 100 to 107. In the present embodiment, the lighting ON / OFF button 226 is divided into an ON button and an OFF button, but it is not limited thereto, and by operating one button a plurality of times, the lighting and extinguishing of the emergency light-emitting unit 170 provided in the lighting fixtures 100 to 107 may be operable.

[0041] The battery display area 228 is configured to be able to display the remaining battery level of the emergency power source 150 provided in the lighting fixtures 100 to 107 received by the communication unit 230 described later from the lighting fixtures 100 to 107, and the result calculated by the remaining amount calculation unit 166 of the emergency control unit 160 provided in the lighting fixtures 100 to 107. By having such a configuration, the user can operate the illumination state of the emergency light-emitting unit 170 while checking the remaining battery level of the emergency power source 150 provided in the lighting fixtures 100 to 107 and the estimated continuous lighting time of the emergency light-emitting unit 170.

[0042] The communication unit 230 is configured to be able to communicate with the communication unit 60 of the power outage detection device 10, the communication unit 140 of another lighting fixture, and the emergency communication unit 180. Specifically, the communication unit 230 is configured to be able to receive a power outage detection signal transmitted from the communication unit 60 of the power outage detection device 10. Further, the communication unit 230 is configured to be able to receive the remaining power information of the emergency light from the emergency communication unit 180 provided in the lighting fixtures 100 to 107, and is configured to be able to transmit an operation signal to the communication unit 140 and the emergency communication unit 180 provided in the lighting fixtures 100 to 107.

[0043] The operation terminal 200 further includes a lighting 240 and a speaker 250, and the display unit 220 further includes a notification area (not shown). The operation terminal 200 having such a configuration is configured such that when the main control unit 210 receives a power outage detection signal transmitted from the power outage detection device 10, the main control unit 210 turns on the lighting 240 and causes the speaker 250 to emit a notification sound.

[0044] The operation terminal 200 having the above configuration is configured to be able to control the illumination state of the emergency light-emitting unit 170 provided in the lighting fixtures 100 to 107 by operating the display unit 220. Since it is possible to turn on and dim only the necessary emergency lights according to the situation, it is possible to prevent all the emergency lights from running out of battery at the same time and to know in advance the time until the battery runs out.

[0045] For the communication between the power failure detection device 10, the lighting fixtures 100 to 107, and the operation terminal 200, short-range wireless communication in the 2.4 GHz band is preferably used, but it is not limited thereto. Various arbitrary frequency bands and wireless communication standards such as the 920 MHz band and the 5 GHz band called the sub-giga band can be adopted. For example, when using Bluetooth (registered trademark), which is a short-range wireless communication standard using the 2.4 GHz band, the power consumption required for communication can be suppressed, and it becomes possible to keep the emergency lights on for a longer time. Further, as other short-range wireless communication standards using the 2.4 GHz band, for example, Wi-Fi and ZigBee (registered trademark) can be mentioned.

[0046] [Description of Operations] Next, the operation procedure during a power failure of the power failure lighting system 1 according to the present embodiment will be described with reference to FIG. 6. FIG. 6 is an example of a flowchart showing a series of flows of the operation method. In the flowchart of FIG. 6, the lighting order of the lighting fixtures 100 to 107 is not set by the lighting order operation unit 216 of the operation terminal 200, and no relay lighting signal is transmitted.

[0047] Further, hereinafter, an example in which the lighting fixture 100 receives a power failure detection signal from the power failure detection device 10 will be described, but it is not limited thereto. It is also possible for all the lighting fixtures 100 to 107 to receive the power failure detection signal at the same time, and in that case, the following flow is executed in parallel.

[0048] The power outage lighting system 1 according to this embodiment first has the power outage detection unit 30 of the power outage detection device 10 detect the occurrence of a power outage from the power supply state of the indoor wiring (YES in S1 of FIG. 6). The power outage detection device 10 that has detected a power outage switches to operation by the emergency power supply 40 (S2 in FIG. 6), and the notification control unit 52 of the main control unit 50 transmits a power outage detection signal from the communication unit 60 (S3 in FIG. 6).

[0049] On the other hand, the lighting fixture 100 stops receiving power from the power supply 110 due to a power outage and switches to operation by the emergency power supply 150. The emergency communication unit 180 of the lighting fixture 100 receives the power outage detection signal transmitted from the power outage detection device 10 (S10 in FIG. 6). The lighting fixture 100 that has received the power outage detection signal transmits the power outage detection signal from the emergency communication unit 180 to the lighting fixtures installed within the communication range of the lighting fixture 100 (lighting fixture 101 in this embodiment) (S11 in FIG. 6). The lighting fixture 100 causes the lighting control unit 162 of the emergency control unit 160 to turn on the emergency light emitting unit 170 at a predetermined illuminance simultaneously with or after transmitting the power outage detection signal (S12 in FIG. 6).

[0050] Also, the operation terminal 200 has the communication unit 230 receive the power outage detection signal. The operation terminal 200 that has received the power outage detection signal notifies the user of the power outage and indicates the location of the operation terminal 200 by having the main control unit 210 turn on the lighting 240 and having the speaker 250 emit a notification sound.

[0051] Subsequently, the lighting fixture 101 has the emergency communication unit 180 of the lighting fixture 101 receive the power outage detection signal transmitted from the lighting fixture 100 (S20 in FIG. 6). The lighting fixture 101 that has received the power outage detection signal transmits the power outage detection signal from the emergency communication unit 180 to the lighting fixtures installed within the communication range of the lighting fixture 101 (S21 in FIG. 6). The lighting fixture 101 causes the lighting control unit 162 of the emergency control unit 160 to turn on the emergency light emitting unit 170 at a predetermined illuminance simultaneously with or after transmitting the power outage detection signal (S22 in FIG. 6). Subsequently, the power outage detection signal is transmitted to all the lighting fixtures installed in the building in the same procedure, and the emergency light emitting unit 170 is turned on, so that the lighting fixtures 100 to 107 are turned on as emergency lights.

[0052] When the power outage is restored, the power failure detection unit 30 of the power failure detection device 10 is powered from the indoor wiring, so that the power failure detection device 10 detects the restoration of the power outage (YES in S4 of FIG. 6), and switches from the operation by the emergency power source 150 to the operation by the power supply from the indoor wiring (S5 in FIG. 6). Also, the lighting fixtures 100 to 107 also switch from the operation by the emergency power source 150 to the operation by the power source 110.

[0053] In the power failure detection device 10, the notification control unit 52 of the main control unit 50 transmits a restoration detection signal from the communication unit 60 (S6 in FIG. 6). In the lighting fixture 100, the emergency communication unit 180 of the lighting fixture 100 receives the restoration detection signal transmitted from the power failure detection device 10 (YES in S13 of FIG. 6). The lighting fixture 100 that has received the restoration detection signal transmits the restoration detection signal from the emergency communication unit 180 to the lighting fixture 101 installed within the communication range of the lighting fixture 100 (S14 in FIG. 6). At the same time as or after transmitting the restoration detection signal, the lighting control unit 162 of the emergency control unit 160 of the lighting fixture 100 turns off the emergency light emitting unit 170 (S15 in FIG. 6).

[0054] Subsequently, in the lighting fixture 101, the emergency communication unit 180 of the lighting fixture 101 receives the restoration detection signal transmitted from the lighting fixture 100 (YES in S23 of FIG. 6). The lighting fixture 101 that has received the restoration detection signal transmits the restoration detection signal from the emergency communication unit 180 to the lighting fixtures installed within the communication range of the lighting fixture 101 (S24 in FIG. 6). At the same time as or after transmitting the restoration detection signal, the lighting control unit 162 of the emergency control unit 160 of the lighting fixture 101 turns off the emergency light emitting unit 170 (S25 in FIG. 6). Hereinafter, the restoration detection signal is transmitted to all the lighting fixtures installed in the building in the same procedure, and all the emergency light emitting units 170 are turned off. Through the above steps, a series of operations during a power outage by the power outage lighting system 1 according to the present embodiment are executed.

[0055] In the series of procedures of the above-described operation method, all the lighting fixtures 100 to 107 were described as being lit, but it is also possible to light them in a relay format. Specifically, for example, the lighting order of the lighting fixtures 100 to 107 is set in advance. The lighting fixtures 100 to 107 with the lighting order set are divided into those that receive a power failure detection signal and light up, and those that do not light up even when receiving the power failure detection signal. The lighting fixtures that do not light up even when receiving the power failure detection signal light up by receiving the power failure detection signal and the relay lighting signal transmitted from the lighting fixtures that light up. Also, not limited to this, after receiving the power failure detection signal, the lighting fixtures 100 to 107 may be lit in a relay format by the lighting control unit 162 of the emergency control unit 160 not immediately lighting up the emergency light emitting unit 170 and holding the lighting control for a predetermined time.

[0056] [Advantages of the power failure lighting system according to the present embodiment] As described above, the power failure lighting system 1 according to the present embodiment includes emergency lights (lighting fixtures 100 to 107) that light up during a power failure, and a power failure detection device 10 that can detect a power failure and output a power failure detection signal to the emergency lights (lighting fixtures 100 to 107). The emergency lights (lighting fixtures 100 to 107) are configured to be able to control the illumination state based on the operation signal received from the operation terminal 200.

[0057] And, since the power failure lighting system 1 according to the present embodiment has such a configuration, it is possible to control the illumination state of the emergency lights (emergency light emitting unit 170) by the operation of the user. Therefore, even in the case of a large-scale power failure lasting for a long time or a power failure during a disaster, appropriate measures can be taken according to the situation.

[0058] Also, since the control of the illumination state of the power failure lighting system 1 according to the present embodiment includes on / off control and / or dimming control, it is possible to suppress the power consumption of the emergency lights while ensuring a safe field of vision during a power failure. As a result, compared to the case of continuously lighting at a certain illuminance, there is an advantage that the emergency lights can be lit for a longer time.

[0059] Furthermore, the power failure lighting system 1 according to the present embodiment is configured to be able to display the remaining power information of the emergency lights (lighting fixtures 100 to 107) on the operation terminal 200, so that the user can control the lighting state while checking the remaining power information of the emergency lights (lighting fixtures 100 to 107).

[0060] Moreover, in the power failure lighting system 1 according to the present embodiment, since the remaining power information includes information regarding the remaining battery level and / or information regarding the lighting duration of the emergency lights (lighting fixtures 100 to 107), the user can grasp the time until the emergency light emitting unit 170 turns off due to battery depletion of the emergency power source 150.

[0061] In addition, in the power failure lighting system 1 according to the present embodiment, a plurality of emergency lights (lighting fixtures 100 to 107) are installed, and the plurality of emergency lights (lighting fixtures 100 to 107) are each configured to be able to transmit a power failure detection signal and an operation signal to other emergency lights (lighting fixtures 100 to 107).
