[Prior art documents] [Patent documents]

[0003] [Patent Document 1] Patent No. 6535379 Summary of the Invention [Problem to be solved by the invention]

[0004] However, since conventional emergency lights are constantly lit at a constant illuminance, they are unlikely to cause a major problem in the case of a short power outage, but in the case of a long-lasting large-scale power outage or a power outage during a disaster, the time the emergency lights are lit is insufficient to cover the time it takes to restore power or to prepare for evacuation. In addition, although a user's eyes become accustomed to the emergency lights after spending a long time under them and sufficient visibility can be secured even at illuminance levels lower than the illuminance at which the emergency lights are lit, there is a problem that the emergency lights continue to be lit at a constant illuminance, wasting the battery.

[0009] In the power failure illumination system according to the present invention, the remaining power information may include information relating to a remaining battery charge of the emergency light and / or information relating to a lighting duration.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0015] The best mode for carrying out the present invention will be described below with reference to the drawings. Note that the following embodiments do not limit the inventions according to the claims, and not all of the combinations of features described in the embodiments are necessarily essential to the solution of the invention. The drawings are schematic diagrams in which emphasis, omission, and ratio adjustments have been appropriately made to illustrate the present invention, and may differ from the actual shapes, positional relationships, and ratios.

[0016] [Configuration Description] First, referring to Fig. 1, a power failure lighting system 1 according to an embodiment of the present invention will be outlined. The power failure lighting system 1 according to this embodiment includes lighting fixtures 100-107 that are installed in any space of a building and configured to be able to communicate with each other, a power failure detection device 10 that is connected to indoor wiring and can detect a power failure, and an operation terminal 200 that can operate the lighting fixtures 100-107. The power failure detection device 10 is configured to be able to output a power failure detection signal to the lighting fixtures 100-107 when it detects a power failure. In addition, the lighting fixtures 100-107 further have a function as built-in emergency lights.

[0017] [Configuration of power outage detection device] As shown in FIG. 2, the power outage detection device 10 generally comprises a plug 20 that is inserted into an outlet to receive power, a power outage detection unit 30, an emergency power supply 40 that supplies power to the power outage detection device 10 in the event of a power outage, a main control unit 50, and a communication unit 60 that can transmit a power outage detection signal to the lighting devices 100-107.

[0018] The power failure detection unit 30 is configured to be able to detect a power failure from the power supply state of the indoor wiring. The emergency power supply 40 includes a battery, and is configured to be able to charge the battery by the power supply from the indoor wiring under normal circumstances.

[0019] Main control unit 50 includes a notification control unit 52. Notification control unit 52 is configured to generate a power outage detection signal that is transmitted from communication unit 60 to lighting fixtures 100-107 and operation terminal 200 when power outage detection unit 30 detects a power outage. The power outage detection signal includes a signal notifying that a power outage has been detected. Furthermore, notification control unit 52 is configured to generate a recovery detection signal that is transmitted from communication unit 60 to lighting fixtures 100-107 when power outage detection unit 30 detects recovery from the power outage. The recovery detection signal includes a signal notifying that recovery from the power outage has been detected.

[0020] The communication unit 60 is configured to be able to communicate with the emergency communication units 180 of the lighting fixtures 100 to 107, which will be described later, and the communication unit 230 of the operation terminal 200, which will be described later. Specifically, the communication unit 60 is configured to be able to transmit a power outage detection signal and a recovery detection signal to the emergency communication units 180 of the lighting fixtures 100 to 107, which will be described later, and is configured to be able to transmit a power outage detection signal to the communication unit 230 of the operation terminal 200, which will be described later. In addition, when the power outage detection fixture 10 is installed outside the communication range with the communication unit 230 of the operation terminal 200, which will be described later, the communication unit 60 is configured to be able to transmit a power outage detection signal to the operation terminal 200 via a mesh network constructed by the lighting fixtures 100 to 107.

[0021] The power outage detection device 10 having such a configuration is configured to wait while receiving power from the indoor wiring under normal circumstances, and to be powered by the emergency power source 40 when the power supply from the indoor wiring is cut off in the event of a power outage. Therefore, even during a power outage, it is possible to transmit a power outage detection signal to the emergency communication unit 180 of the lighting devices 100 to 107 described later.

[0022] [Lighting fixture configuration] 3, the lighting devices 100-107 each include a power source 110, a light-emitting unit 130 capable of adjusting the illumination state, a main control unit 120 capable of controlling the illumination state of the light-emitting unit 130, and a communication unit 140, and these components constitute a lighting device that can be used under normal circumstances. Hereinafter, in this specification, "control of the illumination state" refers to control of various illumination states of the light-emitting unit, and includes various types of control, such as on / off control for switching the light-emitting unit on and off, and dimming control for changing the dimming (illuminance) of the light-emitting unit.

[0023] Furthermore, the lighting fixtures 100 to 107 each include an emergency power supply 150, an emergency light-emitting unit 170 capable of adjusting the illumination state, an emergency control unit 160 capable of controlling the illumination state of the emergency light-emitting unit 170, and an emergency communication unit 180, and these components constitute an emergency light that can be used during a power outage. In other words, the lighting fixtures 100 to 107 according to this embodiment are lighting devices with emergency lights. The emergency light configuration may be a built-in configuration that is incorporated in the lighting fixtures 100 to 107 in advance, or may be a unit configuration that can be retrofitted to existing lighting fixtures that do not include an emergency light.

[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. The main control unit 120 also has 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 extinguishing 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] Communication unit 140 is configured to be able to communicate with communication unit 140 of other lighting fixtures and communication unit 230 of operation terminal 200 described below. Specifically, communication unit 140 is configured to be able to receive operation signals transmitted from communication unit 230 of operation terminal 200 described below and communication unit 140 of other lighting fixtures, and is configured to be able to transmit the received operation signals to communication unit 140 of the other lighting fixtures.

[0026] Emergency power supply 150 is equipped with a battery and is configured to charge the battery from the power supply in the indoor wiring when lighting fixtures 100-107 are turned on as normal lighting fixtures, and to supply power to emergency control unit 160, emergency light-emitting unit 170, and emergency communication unit 180 when power supply from the indoor wiring to lighting fixtures 100-107 is no longer provided.

[0027] The emergency control unit 160 includes a lighting control unit 162, a dimming control unit 164, a remaining charge calculation unit 166, and a relay lighting control unit 168. The lighting control unit 162 is configured to be able to control the turning on and off of the emergency light-emitting unit 170, and the dimming control unit 164 is configured to be able to control the illuminance of the emergency light-emitting unit 170. The remaining charge calculation unit 166 is configured to monitor the remaining battery charge of the emergency power supply 150, and to calculate the remaining continuous lighting possible time from the remaining battery charge and the illumination 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 to be transmitted from the emergency communication unit 180 to the other lighting fixtures. For example, when the lighting fixtures 100 to 107 having such a configuration receive a power outage detection signal from the power outage detection device 10, they can turn on only an arbitrary lighting fixture as an emergency light, and transmit a relay lighting signal to the other lighting fixtures before the battery of the emergency power source 150 of the turned-on lighting fixture runs out, thereby making it possible to relay-type turn on the next lighting fixture as an emergency light. Specifically, it is possible to turn on emergency lights installed in the living room, hallway, and entrance sequentially along the evacuation route, or, when there are adjacent lighting fixtures installed within a predetermined range, turn on only one of them, and switch to turning on only the other emergency light before the battery of the emergency power source 150 runs out.

[0029] The emergency communication unit 180 is configured to be able to communicate with the communication unit 60 of the power failure detection device 10, the emergency communication units 180 of the other lighting devices, 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 failure detection signal and a recovery detection signal transmitted from the communication unit 60 of the power failure detection device 10, and is configured to be able to transmit and receive a power failure detection signal and a recovery detection signal to and from the emergency communication units 180 of the other lighting devices. In addition, 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. Furthermore, the emergency communication unit 180 is configured to be able to transmit 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 remaining battery level of the emergency power source 150 and the lighting duration which is the calculation result of the remaining amount calculation unit 166.

[0030] The lighting devices 100-107 having the above configuration are configured such that when a power outage detection signal is received 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 a recovery detection signal is received 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 100-107 are configured to be able to form a mesh network, and a power outage detection signal can be transmitted to a lighting fixture installed outside the communication range of the power outage detection fixture 10 by passing through other lighting fixtures installed within the communication range.

[0032] [Operation terminal configuration] As shown in FIG. 4, the operation terminal 200 is generally equipped with a main control unit 210, a display unit 220, and a communication unit 230. The operation terminal 200 is preferably a portable terminal such as a smartphone, a tablet terminal, or a notebook computer, but is not limited thereto. If the operation terminal 200 is a portable terminal, it is possible to operate the emergency light while moving with the operation terminal 200, and it is possible to evacuate more safely in the event of a disaster. On the other hand, if the operation terminal 200 is a stationary terminal, it is possible to always know where the operation terminal 200 is located, and therefore it is possible to quickly approach the operation terminal 200 after a power outage occurs.

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

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

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

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

[0037] The display areas 220a-220d are graphical user interfaces that can operate the illumination state of the emergency light-emitting unit 170 equipped in the lighting devices 100-107, and the operation terminal 200 is configured so that, when a user operates the display areas 220a-220d of the display unit 220, the main control unit 210 generates an operation signal in accordance with the user's operation, and the communication unit 230 transmits the operation signal.

[0038] Display area 220a is configured to allow the illumination state of emergency light-emitting units 170 provided in lighting fixtures 100-107 to be operated collectively, and display areas 220b-220d are configured to allow the illumination state of emergency light-emitting units 170 provided in lighting fixtures 100-102 to be operated individually.

[0039] The dimming area 222 allows dimming of the emergency light-emitting unit 170 provided in the lighting fixtures 100 to 107, and the illuminance of the emergency light-emitting unit 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 [%] to the brightest state, or an absolute value of the illuminance [lx, lm].

[0040] The light ON / OFF button 226 can be used to turn on and off the emergency light-emitting units 170 included in the lighting devices 100-107. In this embodiment, the light ON / OFF button 226 is a separate ON button and OFF button, but is not limited to this. The emergency light-emitting units 170 included in the lighting devices 100-107 may be turned on and off by operating one button multiple times.

[0041] Battery display area 228 is configured to be able to display the remaining battery charge of emergency power source 150 provided in each of lighting fixtures 100-107, which is received from lighting fixtures 100-107 by communication unit 230, which will be described later, and the result of calculation by remaining charge calculation unit 166 of emergency control unit 160 provided in each of lighting fixtures 100-107. With this configuration, the user can operate the illumination state of emergency light-emitting unit 170 while checking the remaining battery charge of emergency power source 150 provided in each of lighting fixtures 100-107 and the estimated continuous lighting time of 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 and the communication units 140 and emergency communication units 180 of the other lighting devices. 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. In addition, the communication unit 230 is configured to be able to receive remaining power information of the emergency light transmitted from the emergency communication units 180 provided in the lighting devices 100 to 107, and is configured to be able to transmit an operation signal to the communication units 140 and emergency communication units 180 provided in the lighting devices 100 to 107.

[0043] The operation terminal 200 further includes a light 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, upon receiving a power outage detection signal transmitted from the power outage detection instrument 10, the main control unit 210 turns on the light 240 and causes the speaker 250 to emit an alarm 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 units 170 provided in the lighting fixtures 100-107 by operating the display unit 220, and it is possible to turn on and dim only the emergency lights that are necessary depending on the situation, so that it is possible to prevent all the emergency lights from running out of battery power at the same time and to know in advance the time remaining until the batteries run out.

[0045] For communication between the power outage detection device 10, the lighting devices 100 to 107, and the operation terminal 200, short-range wireless communication in the 2.4 GHz band is preferably used, but is not limited thereto, and various arbitrary frequency bands and wireless communication standards such as the 920 MHz band and the 5 GHz band, which are called the sub-giga band, can be adopted. For example, when Bluetooth (registered trademark), which is a short-range wireless communication standard using the 2.4 GHz band, is used, the power consumption required for communication can be reduced, and the emergency light can be turned on for a longer period of time. Other short-range wireless communication standards using the 2.4 GHz band include, for example, Wi-Fi and ZigBee (registered trademark).

[0046] [Explanation of operation] Next, the operation procedure of the power outage lighting system 1 according to this embodiment during a power outage will be described with reference to Fig. 6. Fig. 6 is an example of a flowchart showing a series of steps of the operation method. Note that in the flowchart of Fig. 6, the lighting sequence of the lighting fixtures 100-107 is not set by the lighting sequence operation unit 216 of the operation terminal 200, and no relay lighting signal is transmitted.

[0047] In addition, an example will be described below in which the lighting fixture 100 receives a power outage detection signal from the power outage detection fixture 10, but this is not limited to this, and it is also possible for all lighting fixtures 100 to 107 to receive the power outage detection signal simultaneously, in which case the following flow will be executed in parallel.

[0048] In the power outage lighting system 1 according to this embodiment, first, the power outage detection unit 30 of the power outage detection device 10 detects the occurrence of a power outage from the power supply state of the indoor wiring (if YES in S1 of FIG. 6). The power outage detection device 10 that detects the power outage switches to operation using the emergency power source 40 (S2 of 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 of FIG. 6).

[0049] On the other hand, when power is no longer supplied from power source 110 due to the power outage, lighting device 100 switches to operation using emergency power source 150. In lighting device 100, emergency communication unit 180 of lighting device 100 receives the power outage detection signal transmitted from power outage detection device 10 (S10 in FIG. 6). Having received the power outage detection signal, lighting device 100 transmits a power outage detection signal from emergency communication unit 180 to a lighting device (lighting device 101 in this embodiment) installed within the communication range of lighting device 100 (S11 in FIG. 6). Simultaneously with or after transmitting the power outage detection signal, lighting control unit 162 of emergency control unit 160 of lighting device 100 turns on emergency light-emitting unit 170 at a predetermined illuminance (S12 in FIG. 6).

[0050] Furthermore, the communication unit 230 of the operation terminal 200 receives a power outage detection signal. In the operation terminal 200 that has received the power outage detection signal, the main control unit 210 turns on the lighting 240 and causes the speaker 250 to emit an alarm sound, thereby notifying the user of the power outage and informing the user of the location of the operation terminal 200.

[0051] Next, in lighting fixture 101, emergency communication unit 180 of lighting fixture 101 receives the power outage detection signal transmitted from lighting fixture 100 (S20 in FIG. 6). Having received the power outage detection signal, lighting fixture 101 transmits a power outage detection signal from emergency communication unit 180 to lighting fixtures installed within the communication range of lighting fixture 101 (S21 in FIG. 6). Simultaneously with or after transmitting the power outage detection signal, lighting control unit 162 of emergency control unit 160 of lighting fixture 101 turns on emergency light-emitting unit 170 at a predetermined illuminance (S22 in FIG. 6). Thereafter, the power outage detection signal is transmitted to all lighting fixtures installed in the building in a similar procedure, and emergency light-emitting unit 170 is turned on, causing lighting fixtures 100 to 107 to light up as emergency lights.

[0052] When the power outage is restored, the power outage detection unit 30 of the power outage detection device 10 is supplied with power from the indoor wiring, so that the power outage detection device 10 detects the restoration of the power outage (YES in S4 of FIG. 6) and switches from operation based on the emergency power source 150 to operation based on power supplied from the indoor wiring (S5 of FIG. 6). In addition, the lighting devices 100 to 107 also switch from operation based on the emergency power source 150 to operation based on the power source 110.

[0053] In the power outage 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 device 100, the emergency communication unit 180 of the lighting device 100 receives the restoration detection signal transmitted from the power outage detection device 10 (if YES in S13 in FIG. 6). Having received the restoration detection signal, the lighting device 100 transmits the restoration detection signal from the emergency communication unit 180 to the lighting device 101 installed within the communication range of the lighting device 100 (S14 in FIG. 6). Simultaneously with or after transmitting the restoration detection signal, the lighting control unit 162 of the emergency control unit 160 in the lighting device 100 turns off the emergency light-emitting unit 170 (S15 in FIG. 6).

[0054] Next, the emergency communication unit 180 of the lighting fixture 101 receives the restoration detection signal transmitted from the lighting fixture 100 (if YES in S23 in FIG. 6). Having received the restoration detection signal, the lighting fixture 101 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). Simultaneously with 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). Thereafter, the restoration detection signal is transmitted to all lighting fixtures installed in the building in a similar procedure, and all emergency light-emitting units 170 are turned off. A series of operations during a power outage by the power outage lighting system 1 according to this embodiment are performed by the above-mentioned steps.

[0055] In the above-described series of steps of the operation method, all of the lighting fixtures 100 to 107 are described as being turned on, but it is also possible to turn them on 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 for which the lighting order is set are divided into lighting fixtures that receive a power outage detection signal and turn on, and lighting fixtures that do not turn on even when they receive a power outage detection signal. The lighting fixtures that do not turn on even when they receive a power outage detection signal turn on when they receive a relay lighting signal transmitted from a lighting fixture that receives a power outage detection signal and turns on. In addition, without being limited to this, the lighting control unit 162 of the emergency control unit 160 may not immediately turn on the emergency light-emitting unit 170 after receiving the power outage detection signal, but may reserve lighting control for a predetermined time, thereby turning on the lighting fixtures 100 to 107 in a relay format.

[0056] [Advantages of the lighting system during power outages according to this embodiment] As described above, the power outage lighting system 1 of this embodiment includes emergency lights (lighting fixtures 100-107) that turn on during a power outage, and a power outage detection fixture 10 that can detect a power outage and output a power outage detection signal to the emergency lights (lighting fixtures 100-107). The emergency lights (lighting fixtures 100-107) are configured to be able to control their illumination state based on an operation signal received from the operation terminal 200.

[0057] Furthermore, by being equipped with such a configuration, the power outage lighting system 1 according to this embodiment makes it possible to control the illumination state of the emergency light (emergency light-emitting unit 170) through user operation, so that appropriate measures can be taken according to the situation even in the case of a long-lasting large-scale power outage or a power outage during a disaster.

[0058] Furthermore, in the power outage lighting system 1 of this embodiment, the control of the illumination state includes on / off control and / or dimming control, which makes it possible to reduce the power consumption of the emergency light while ensuring a safe field of vision during a power outage.
