Description

[Technical field]

[0001] The present invention relates to lighting fixtures such as ceiling lights that use light-emitting elements such as LEDs, which can be used as normal lighting fixtures under normal circumstances and as disaster prevention lighting fixtures in emergencies. [Background technology]

[0002] Generally, lighting fixtures such as ceiling lights that use light-emitting elements such as LEDs are widely used in general buildings such as ordinary detached houses and apartment buildings. Lighting fixtures such as ceiling lights are usually supplied with commercial power from a fixture (wiring device) installed on the ceiling (the fixture mounting surface), and can be turned on / off by using a wall switch or by operating the buttons on a remote controller (remote control) that comes with the lighting fixture.

[0003] If a natural disaster such as an earthquake or typhoon occurs, or if a power generation facility malfunctions and the commercial power supply is cut off, or if an overcurrent occurs in the home and the safety breaker trips, cutting off the power supply, a power outage will occur and the lighting fixtures will suddenly go out. In particular, if a power outage occurs at night, you will have to search for flashlights, lanterns, and candles in the dark, and if the safety breaker trips, you will have to search for the switch on the distribution board. In such cases, if the lighting fixtures installed on the ceiling were equipped with disaster prevention (emergency) lighting devices that could be turned on in an emergency, people would not have to search for a flashlight or other light in the sudden darkness, which would reduce their anxiety.

[0004] As a countermeasure against sudden power outages, lighting fixtures equipped with an emergency power source (battery) that turns on in an emergency are known. When this lighting fixture detects a power outage, it turns on by receiving power from the emergency power source (battery) and serves as an emergency light (Patent Document 1). [Prior art documents] [Patent documents]

[0005] [Patent Document 1] Japanese Patent Application Publication No. 10-92586 Summary of the Invention [Problem to be solved by the invention]

[0006] Patent Document 1 describes a lighting fixture that is installed on the ceiling and has a battery inside it, and a remote control transmitter that transmits a power outage detection signal in the event of a commercial power outage is set and kept connected to a power outlet at all times, and in the event of a power outage, the lighting fixture is turned on by the power outage detection signal transmitted from the remote control transmitter. However, this lighting fixture requires the remote control transmitter to be set and always connected to a power outlet. Furthermore, because this lighting fixture is a round ceiling light that uses a fluorescent lamp, it requires more power than light-emitting elements such as LEDs, and the lighting time is short, so in order to ensure a certain level of lighting time, it is necessary to have a large-capacity battery.

[0007] Therefore, in order to solve the problems of the prior art documents, the present invention provides a lighting fixture such as a ceiling light that uses an LED as a light source, which has a power outage detection function and has a battery holder attached inside, and by placing a battery in the battery holder so that it can be freely attached and detached, the lighting fixture functions as a lighting fixture under normal circumstances in a simple manner, and as a disaster prevention light (emergency light) that is lit for a certain period of time in an emergency. [Means for solving the problem]

[0008] In order to achieve the above object, a lighting fixture according to an aspect of the present invention comprises: A battery holder that is attached to a lighting fixture and to which a battery is detachably attached, the battery holder has an annular portion attached to a flat portion formed around an opening of the lighting fixture having a circular, flat body with an opening at the center, and legs located on a lower surface of the annular portion and holding the battery; When the battery holder is attached to the lighting fixture and the battery is attached to the battery holder, power is normally supplied from a commercial power source to the light source of the lighting fixture and the battery, and when a power outage occurs, power is supplied from the battery to the light source. Effect of the Invention

[0009] According to the present invention, a battery is placed inside a lighting fixture which is attached to a mounting fixture (wiring device) installed on the ceiling (mounting section), and the lighting fixture can be turned on using power supplied from the battery during a power outage, allowing the lighting fixture to function as a disaster prevention light that can be turned on for a certain period of time without the need for special construction work.

[0029] The shade 90 shown in FIG. 1 is detachably attached so as to cover the entire front part of the LED light source cover 31 and the main body 10. The shade 90 is formed from a translucent acrylic resin or polycarbonate resin having a diffusive property such as milky white, and is formed in a hollow circular shape with an opening on one side. The shade 90 is a member having a function of efficiently diffusing the light emitted from the light source 30, and is called a globe or the like. A holding part 14 is provided on the flat part 11 of the main body 10, and the edge of the shade 90 engages with the holding part 14 of the main body 10, so that the shade 90 is detachably held on the main body 10. As described above, the shade 90 is an optional member.

[0030] 10(A) is a side view of a battery holder 80 according to the embodiment, FIG. 10(B) is a top view, FIG. 10(C) is a bottom view, and FIG. 10(D) is a perspective view.

[0031] The battery holder 80 is attached to the main body 10 and holds the freely attachable battery 70. It has a circular annular portion 82 and a cylindrical co-fastening boss 83 with a slightly tapered side provided on the upper surface of the annular portion. The co-fastening bosses 83 are disposed at positions facing each other on the surface of the annular portion 82. A pair of legs 81 are fixed to the lower surface of the annular portion 82 adjacent to the hole 84 and perpendicular to the lower surface of the annular portion 82. The tip of the leg 81 is formed in an L-shape toward the inside of the annular portion. In addition, a pair of cutouts 85 are formed in the annular portion 82.

[0032] The battery holder 80, the LED light source cover 31 and the main body 10 are screwed together by inserting a screw through the hole 84 of the co-fastening boss 83, the hole 33 of the LED light source cover 31 and the hole 20 of the main body 10 and screwing them.

[0033] FIG. 11(A) is a side view of a battery 70 according to the embodiment, FIG. 11(B) is a top view, FIG. 11(C) is a bottom view, and FIG. 11(D) is a perspective view.

[0034] Battery 70 has a two-stage shape consisting of a disk-shaped upper stage portion 77 and a disk-shaped lower stage portion 78 that is larger than upper stage portion 77. Upper stage portion 77 has two groove portions 73 that face each other on its side surface. Groove portion 73 has fitting portion 74 having a recess that fits from the top surface to the bottom surface on the side surface of upper stage portion 77, and fixing portion 75 that is recessed along the side surface. A protrusion 76 is provided between fitting portion 74 and fixing portion 75.

[0035] A pigtail cable 79 with a power terminal at its tip extends from the side surface of the upper section 77 of the battery 70. A USB terminal 71 and an indicator 72C that shows the usage state of the battery 70 are provided on the bottom surface of the lower section 78 of the battery 70, as shown in Fig. 11(C).

[0036] FIG. 12(A) is a side view showing a state in which a battery 70 according to the embodiment is attached to a battery holder 80, FIG. 12(B) is a top view, and FIG. 12(C) is a perspective view.

[0037] The battery 70 is detachably attached to the battery holder 80. Specifically, the fitting portion 74 of the battery 70 is fitted to a pair of legs 81 of the battery holder 80 attached to the main body 10, the legs 81 are placed on the upper surface of the lower stage portion 78 of the battery 70, and the battery 70 is rotated counterclockwise as viewed from above, so that the tip of the legs 81 moves along the fixing portion 75 of the battery 70, thereby fixing the battery 70. Since the fixing portion 75 is provided with a protrusion 76, the legs 81 are fixed so as not to come off the battery holder 80. When the battery 70 is to be removed from the battery holder 80, the battery 70 can be easily removed by lifting it up and rotating it clockwise.

[0038] By adding a light source such as an LED to the battery 70, it can be removed and used as a flashlight, or the DC power output from the USB terminal 71 can be used as an emergency power source for charging a mobile phone, etc. In addition, since the battery 70 is a commercially available battery, it can be purchased at a low price and multiple batteries can be owned as spares. By owning multiple batteries 70, the lighting fixture 1 can be expected to stay lit for a longer period of time, providing peace of mind during a power outage.

[0039] FIG. 13(A) is a side view of the mounting adaptor 3 according to the embodiment, FIG. 13(B) is a top view, FIG. 13(C) is a bottom view, and FIG. 13(D) is a perspective view.

[0040] The mounting adapter 3 is a member with a circular cross section and has a pair of hooks 6 on its top surface, a pair of claws 5 on its side surface, and a pair of release levers 4 on its bottom surface. The hooks 6 of the mounting adapter 3 fit into a pair of engagement grooves in the fixture 2 arranged on the ceiling 9, respectively, for mechanical connection and electrical connection to a commercial power source.

[0041] 1 and 14(A), the mounting fixture 2 is a member for mounting the main body 10 to the installation location of the lighting fixture 1. The mounting fixture 2 is a member called a ceiling hook, a ceiling hook body, or the like.

[0042] The claw 5 is a member for removing the mounting adapter 3 from the attachment fixture 2. By pinching the release lever 4 with the fingers and pulling it inward, the claw 5 is moved toward the center of the mounting adapter 3 and the mounting adapter 3 is rotated horizontally, thereby removing the mounting adapter 3 from the attachment fixture 2.

[0043] FIG. 14(A) is a cross-sectional perspective view of the lighting fixture 1 shown in FIG. 4 taken along the line AA, and FIG. 14(B) is a side view of a main portion.

[0044] Hereinafter, the structures of the main body 10 and the light source 30 will be described with reference to cross-sectional views. Note that in Fig. 14 and other figures, components such as the LED board 40 are illustrated as schematic cross-sectional views, and hatching representing the cross section and internal structures are omitted.

[0045] 14(A) and (B) are both cross-sectional views of the luminaire 1 shown in Fig. 4 taken along line AA, and show the luminaire 1 installed on a ceiling 9. The main body 10 is attached by engaging the hook 6 of the mounting adapter 3 with the fixture 2 installed on the ceiling 9.

[0046] The light source 30 is formed in an annular shape with an opening 13 in the center, and has an LED light source cover 31 covering the front side, and inside the cover 31, an annular LED board 40 and LEDs 41 surface-mounted on the LED board 40 are arranged. The front side of the LED board 40 and the flat plate constituting the main body 10 arranged in the light source 30 are painted with white paint or the like, and by applying the white paint, the irradiated light emitted by the LEDs 41 can be efficiently reflected to the front side of the lighting fixture 1.

[0047] Here, a method of attaching the lighting fixture 1 to the mounting fixture 2 will be described. First, the mounting adapter 3 is attached to the mounting fixture 2. Next, the main body 10 of the lighting fixture 1 is held, and the mounting adapter 3 is inserted into the opening 13 provided in the main body 10. Then, when the main body 10 is lifted up so as to push up the tabs 5 of the mounting adapter 3 from below, the tabs 5 are pushed into the inside of the mounting adapter 3 by the edge of the annular portion 82 of the battery holder 80 attached to the main body 10. When the main body 10 is lifted up in this state, the tabs 5 climb over the edge of the annular portion 82 of the battery holder 80, and the tabs 5 are positioned below the annular portion 82. Since the tabs 5 are biased toward the outside of the mounting adapter 3, they protrude outward again and support the main body 10 from below.

[0048] To remove the main body 10 from the mounting adapter 3, if there is a shade 90, the shade 90 is removed from the main body 10, and then a pair of release levers 4 provided on the bottom surface of the mounting adapter 3 is used. By simultaneously placing hands on the pair of release levers 4 and pulling them inward, the claws 5 retract into the mounting adapter 3, the engagement with the annular portion 82 is released, and the main body 10 is removed from the mounting adapter 3.

[0049] The LED substrate 40 is an annular flat plate having an opening in the center. The LEDs 41 mounted on the surface of the LED substrate 40 are substantially rectangular parallelepiped in shape, and are mounted on the LED substrate 40 in an annular shape at substantially equal intervals. The LEDs 41 are made up of warm white LEDs 42, daylight white LEDs 43, and hotaluk LEDs 44 (also called "afterglow LEDs"; "Hotalook" (registered trademark)).

[0050] The warm white LED 42 and the daylight white LED 43 are LEDs that emit warm white and daylight white light, respectively, and the firefly LED 44 is an LED that glows as an afterglow for a certain period of time after the LEDs of the lighting fixture 1 are turned off.

[0051] On the surface of the LED substrate 40, the LEDs 41 are arranged in a ring shape around the opening, and the warm white LEDs 42 and the daylight white LEDs 43 are arranged alternately in the same row. The ring-shaped row of the LEDs 41 may be a single row or multiple rows. The LEDs 41 may be arranged in a lattice shape on the LED substrate 40. The warm white LEDs 42 and the daylight white LEDs 43 in the LEDs 41 do not need to be arranged alternately, and the warm white LEDs 42 may be arranged in the same row and the daylight white LEDs 43 in another row. The firefly LEDs 44 can be disposed at suitable locations on the LED board 40, for example, around the opening or periphery of the LED board 40, or between the warm white LEDs 42 and the daylight white LEDs 43. As in other drawings, in Fig. 14 and the like, parts such as cords and connectors connected to the mounting adapter 3 and the LED board 40 are omitted except for some parts.

[0052] FIG. 15 is a schematic diagram showing a circuit configuration of a lighting fixture 1 according to an embodiment. A power supply board 50 is disposed in the light source 30 so as to surround the opening 13. The power supply board 50 is mounted with a dimming and color-adjusting power supply circuit 51 configured as a power supply circuit for the normal lighting fixture 1, and a battery power supply circuit 60 equipped with a power failure lighting circuit that charges the battery 70 during normal times and turns on the lighting fixture 1 in an emergency during a power failure. The dimming and color-adjusting power supply circuit 51 controls the applied voltage and current to adjust the brightness of the light source 30, such as turning it on / off or dimming it, and to adjust the color, such as individually emitting the warm white LED 42 and the daylight white LED 43 or emitting a mixed color of these. These dimming and color adjustment operations can be performed by operating the remote controller 100.

[0053] The dimming and color adjusting power supply circuit 51 is composed of a PFC circuit (power factor correction circuit) 52, a DC / DC circuit 53, a remote control light receiving circuit 54, a dimming / color adjusting circuit 55, a firefly lighting circuit (afterglow LED lighting circuit) 56 and an LED circuit 40.

[0054] The battery power supply circuit 60 is made up of a PFC circuit (power factor correction circuit) 61, a power supply circuit 62, a remote control light receiving circuit 63, and a power failure LED lighting circuit (boost circuit) 64. The battery 70 is made up of a battery main body 72A, a battery charging circuit 72B, and an indicator 72C.

[0055] Emergency lights, generally stipulated in the Electrical Appliance and Material Safety Law and certified by the Japan Lighting Manufacturers Association, use nickel-metal hydride batteries (Ni-MH), which comply with the JIS standard, as batteries and are inexpensive as they do not require control circuits. However, they require a dedicated circuit for constant charging, have a short replacement guideline of between four and six years, and are required to be continuously lit when in an emergency. The continuous lighting time of light source 30 in lighting device 1 of the present invention is designed to last for approximately 10 hours, although this depends on the capacity of battery 70. For example, a lithium iron phosphate battery is used as battery 70. Among lithium ion batteries, this battery is characterized by its resistance to overcharging / overdischarging and its long life.

[0056] In addition, disaster prevention lights generally use dedicated batteries, making the lighting fixtures themselves expensive, but the battery 70 of the present invention can use a commercially available general-purpose battery, so it can be supplied to the market as an inexpensive lighting fixture despite having a disaster prevention function.

[0057] The AC power supplied from the power source passes through a PFC circuit (power factor correction circuit) 52 and a DC / DC circuit 53, then branches in three directions and is connected to a dimming / color-adjusting circuit 55, a remote control light receiving circuit 54, and a firefly lighting circuit 56. An instruction signal issued by operating a button on the remote controller 100 is received by the remote control light receiving circuit 54, which transmits the instruction signal to a dimming / color-adjusting circuit 55 that adjusts the brightness such as turning on / off and dimming, and adjusts the color such as incandescent light color and daylight color, thereby controlling the output of the LED circuit 40. When the power supply to the LED circuit 40 is stopped by turning off the lighting fixture 1, power is supplied from the firefly lighting circuit 56 to the firefly LED 44, and the firefly LED 44 lights up.

[0058] On the other hand, AC power supplied from a commercial power source passes through a PFC circuit (power factor correction circuit) 61, and then DC power is supplied to the battery 70 through a power supply circuit 62. A pigtail cable 79 extending from the battery 70 is connected to a connector (not shown) of the power supply circuit 62, and DC power is supplied to a battery main body 72A in the battery 70. The output voltage of the power supply circuit 62 is, for example, DC 24V.

[0059] Battery 70 is made up of a battery main body 72A, a battery charging circuit 72B, and an indicator 72C. Indicator 72C is made up of three green LEDs arranged on the bottom surface of battery 70, and the remaining battery charge is indicated by the number of lit LEDs. For example, three lit LEDs indicate a full battery charge, two lit LEDs indicate a medium battery charge, and one lit LED indicates a low battery charge. A green LED is used for indicator 72C, but this is not limiting and other colored LEDs such as red and yellow LEDs may also be used.

[0060] The DC power output from the USB terminal 71, the battery charging circuit 72B, and the pigtail cable 79 is 5V / 1A, but is not limited thereto and may be 5V / 0.1-3.0A, 9V / 1.7-3.0A, 15V / 1.8-3.0A, 20V / 2.25-5.0A, etc. The power supply circuit 62 is connected to the battery charging circuit 72B as well as to an LED lighting circuit 64 that controls boosting of the DC power. When the power supply from the power supply circuit 62 is stopped, the LED lighting circuit 64 detects a power outage and is excited, and DC power is output from the battery 70 to the warm white LED 42 and the daylight white LED 43, starting emergency lighting.

[0061] During a power outage, the remote control light receiving circuit 63 operates by receiving DC power from the battery main body 72A.

[0062] The battery power supply circuit 60 is provided with a remote control light receiving circuit 63, which receives an emergency lighting on / off signal from the remote controller 100 to turn on / off the emergency lighting. For example, even if the lighting fixture 1 is turned off and emergency lighting is started due to a power outage or the like, there may be cases where it is daytime and the room is bright and there is no need to turn on the lighting fixture 1. In such cases, the emergency lighting of the lighting fixture 1 can be dimmed or turned off by operating the operation switches 101 and 102 of the remote controller 100 to prevent unnecessary consumption of the battery 70. This is particularly effective when the power outage lasts for a long period of time. By using a commercially available inexpensive product as the battery 70, the production cost of the lighting fixture 1 can be reduced. In addition, since the battery 70 can be easily removed from the battery holder 80 of the lighting fixture 1, a spare battery 70 can be prepared and fully charged in advance, and by replacing the battery 70 with a new battery 70 when the remaining power of the previous battery 70 runs out, it is possible to continue the emergency lighting for a long period of time.

[0063] Remote control light receiving circuits 54, 63 include a receiving section (not shown) that receives a signal transmitted from remote controller 100 and transmits the received signal to dimming / color adjustment circuit 55 and LED lighting circuit 64. Remote controller 100 outputs an infrared signal indicating the contents of an instruction (control contents of how lighting device 1 is to be controlled) by an operation performed by a user or the like. The infrared signal may be, for example, a signal indicating an IR (Infrared) code indicating the control contents. Remote controller 100 outputs an infrared signal indicating the control contents of lighting device 1, for example, by outputting an infrared signal indicating an IR code corresponding to the operation contents.

[0064] The infrared signal transmitted from the remote controller 100 is received by the receiving section of the remote control light receiving circuit 54, 63. The receiving section is composed of a light receiving element (e.g., an infrared sensor) capable of receiving an infrared signal. The infrared signal received by the receiving section is converted into an electric signal and output to the dimming / color adjustment circuit 55 and the LED lighting circuit 64.

[0065] The dimming / color adjustment circuit 55 controls the warm white LED 42 and the daylight white LED 43 to adjust the light intensity and color by turning them on / off and dimming them according to the electric signal (e.g., the control contents indicated by the infrared signal) supplied from the receiving unit. The LED lighting circuit 64 turns the emergency lights on / off according to the electric signal supplied from the receiving unit.

[0066] That is, the remote control light receiving circuit 54 functions as a detection unit that detects an infrared signal transmitted from the remote controller 100. The operation of these receiving units, the dimming / color adjusting circuit 55, the LED lighting circuit 64, etc. realizes remote control of the light source 30 by the remote controller 100.

[0067] The remote controller 100 is provided with a dimmer switch 101 and a color adjustment switch 102 as operation switches. The dimmer switch 101 is used to turn on / off the lighting fixture 1, and the color adjustment switch 102 can adjust the color of the illumination emitted by the light source 30 to a color desired by the user, such as daylight color or warm white.

[0068] For example, when a user operates the dimmer switch 101 of the remote controller 100 to turn on the light source 30, an infrared signal indicating turning on is supplied to the light source 30, and the dimming / color adjustment circuit 55 turns on the light source 30 based on the infrared signal received by the receiving unit. When a user operates the remote controller 100 to turn off the light source 30, an infrared signal indicating turning off is supplied to the light source 30, and the dimming / color adjustment circuit 55 turns off the light source 30 based on the infrared signal received by the receiving unit. When a user operates the color adjustment switch 102, the remote controller 100 transmits an instruction signal indicating dimming and what type of dimming to perform, and the color of the light source 30 is adjusted.

[0069] The wireless communication between the remote controller 100 and the receiving unit may use, in addition to infrared signals, specific low-power radio of 2.4 GHz, radio in other frequency ranges, ZigBee (registered trademark), Bluetooth (registered trademark), Wi-Fi (registered trademark), infrared communication, etc.

[0070] When the commercial power supply is interrupted and a power outage occurs, the power supply to the lighting fixture 1 is interrupted. The LED lighting circuit 64 detects that the power supply has been interrupted, and outputs DC power from the battery 70 to supply the DC power to the LED board 40. The LED circuit 40 that has received the power supply turns on the light source 30 with the DC power output from the battery 70, and starts emergency lighting.

[0071] During emergency lighting of lighting fixture 1 due to a power outage caused by a commercial power interruption, DC power is continuously output from battery 70, and the lighting state (emergency lighting) is maintained. Fig. 16(B) shows a perspective view of remote controller 100. When the light of lighting fixture 1 is not needed, as in normal times, operating dimmer switch 101 provided on remote controller 100 will turn lighting fixture 1 off, and operating it again will turn lighting fixture 1 on. In other words, lighting fixture 1 can be turned on / off by operating dimmer switch 101. Lighting fixture 1 can also be operated with color adjustment switch 102 in the same way as in normal times.

[0072] For example, even in the event of an emergency such as a power outage, when the light from lighting device 1 is not needed, such as during the day when the room is sufficiently bright, lighting device 1 can be turned off by operating operation switch 111 of remote controller 100 to conserve power in battery 70 and prepare for lighting at night. Also, when needed, lighting device 1 can be turned on by operating operation switch 111.

[0073] As described above, remote controller 100 is provided with dimmer switch 101 and color adjustment switch 102 for turning lighting fixture 1 on and off, and light source 30 may further be provided with an illuminance sensor for detecting brightness and a human presence sensor for detecting human movement. This makes it possible to add functions such as (1) not turning on the emergency light when the room is bright even during a power outage, (2) turning off the light when the room becomes bright in the morning, and (3) not turning on the light when no one is present during emergency lighting of lighting fixture 1 due to an earthquake or the like, thereby enabling efficient operation of lighting fixture 1 including battery 70, such as saving power for battery 70 and extending the replacement period.

[0074] According to the present invention, by providing a battery 70 in a lighting fixture 1 equipped with a light source 30, the lighting fixture can function as a lighting fixture under normal circumstances, and in an emergency, by supplying power from the battery provided in the lighting fixture, the lighting fixture can function as a disaster prevention light that can be turned on for a long period of time without the need for dedicated construction.

[0075] 16(A) shows a front view of the wall switch cover 115. In a typical home, when the lighting fixture 1 is turned off by an operation switch 111 such as a wall switch 110 used to turn the lighting fixture 1 on and off, the LED lighting circuit 64 of the lighting fixture 1 cannot detect a power outage. In other words, when viewed from the lighting fixture 1 side, the wall switch 110 has already caused a power outage, so that the battery power supply circuit 60 does not operate even if a power outage occurs. For this reason, by covering the wall switch 110 with a wall switch cover 115 for preventing the operation of the wall switch 110, the present invention can be implemented in a simple manner without the user using the wall switch 110 or without wiring work or the like.

[0076] The wall switch cover 115 covers the entire wall switch 110 from above, and by attaching double-sided tape or adhesive to the sides of the wall switch cover 115 and fixing it to the panel of the wall switch 110, it is possible to prevent the user from touching the wall switch 110.

[0077] It should be noted that the present invention is not limited to the above-described embodiment, and various modifications and applications of the above-described embodiment are possible.

[0078] In this way, the present invention provides a lighting fixture 1 with a power outage detection function, such as a ceiling light that uses an LED as a light source, that functions as a lighting fixture 1 under normal circumstances and as a disaster prevention light (emergency light) that turns on for a certain period of time in an emergency such as when the power is turned on, by attaching a battery holder 80 to the lighting fixture 1 and arranging a battery in a manner that allows it to be attached and removed freely.

[0079] Furthermore, the present invention can provide a lighting fixture 1 that can be fitted with a freely attachable battery 70 so that the lighting fixture 1 can remain lit for a long period of time even in the event of a power outage caused by a natural disaster such as an earthquake, and that can also be operated to turn the lighting on and off even in an emergency.
