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 ordinary buildings such as ordinary detached houses and apartment complexes. 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 operating a wall switch or 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 and cuts off the power, a power outage will occur and lighting fixtures will suddenly go out. Particularly when a power outage occurs at night, you will have to grope around in the dark looking for flashlights, lanterns, and candles, and if the safety breaker trips, you will have to search for the switch on the distribution board. In such cases, if ceiling-mounted lighting fixtures are equipped with disaster prevention (emergency) lighting devices that can be turned on in an emergency, people will not have to search for flashlights or other light sources in the sudden darkness, which will reduce their anxiety.

[0004] Therefore, as a measure against sudden power outages, lighting fixtures equipped with an emergency power source (battery) that lights up in an emergency are known. When this lighting fixture detects a power outage, it lights up using power supplied 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 sends out a power outage detection signal in the event of a commercial power outage is set in a permanently connected state to a power outlet, and in the event of a power outage, the lighting fixture is turned on by the power outage detection signal sent from the remote control transmitter. However, this lighting fixture requires the remote control transmitter to be set and plugged into a power outlet at all times.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 its lighting time is short, so in order to ensure a certain level of lighting time, it is necessary to equip it with 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 it, and by placing a battery in the battery holder so that it can be attached and detached freely, the lighting fixture functions as a lighting fixture under normal circumstances and as a disaster prevention light (emergency light) that turns on for a certain period of time in an emergency, in a simple manner. [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 a circular, flat body with an opening at the center of the lighting fixture, and includes: an annular portion to be attached to a flat surface formed around the opening; and legs located on a lower surface of the annular portion and for 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 in the event of a power outage, power is supplied from the battery to the light source. [Effects of the Invention]

[0009] According to the present invention, a battery is placed inside a lighting fixture that is attached to a mounting fixture (wiring device) installed on the ceiling (mounting section), and the lighting fixture is 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.

[0014] In a typical home, a fixture 2 called a ceiling hook rosette, ceiling hook body, ceiling hook, or ceiling hook rosette is attached to a ceiling 9 for attaching a ceiling light or the like. The fixture 2 outputs commercial power and connects to a lighting fixture 1.

[0015] As shown in Fig. 1, lighting fixture 1 according to the embodiment has light source 30 attached to the front side of main body 10, and light source 30 and the entire front portion of main body 10 are covered by shade 90. Main body 10 is supported by fixture 2 on an installation location (fixture mounting surface) of lighting fixture 1, such as ceiling 9. Light source 30 is a component that emits light in lighting fixture 1, and is also called a light source module, light source unit, or the like.

[0016] In addition, the shade 90 is optional and not necessarily required for the lighting fixture 1 of the present invention. In that case, the holder 14 formed on the main body 10 is not necessary.

[0017] The light source 30 is arranged in the main body 10 so as to surround the central opening 13. Figure 2 shows the circular main body 10, the LED light source cover 31, and the battery 70 attached to the main body 10.

[0018] The main body 10 is formed from a substantially circular flat plate with an opening 13 in the center. As shown in Fig. 3, a mounting adapter 3 is attached to the back surface (rear side) of the main body 10 in a state where it is fitted into the opening 13. A protrusion 18 is also formed on the rear side of the main body 10. Fig. 4 shows a light source 30 arranged on the front side of the main body 10 and a battery 70 attached to the opening 13 of the main body 10 provided near the center.

[0019] FIG. 5(A) is a side view showing the main body 10 and the light source 30 according to the embodiment, and FIG. 5(B) is a perspective view.

[0020] FIG. 5A shows the main body 10 and the light source 30 arranged on the front side of the main body 10.

[0021] 5(B), an opening is provided in the center of the annular light source 30, which communicates with the opening 13 of the main body 10. The annular light source 30 having the opening 13 in the center and the annular main body 10, which is slightly larger than the light source 30, are shown.

[0022] FIG. 6 is a side view of the main body 10 according to the embodiment, FIG. 7 is a front view, and FIG. 8 is a rear view.

[0023] 6, main body 10 has a shape in which trapezoidal convex portion 18 is formed on flat portion 11. Here, when lighting fixture 1 is installed on ceiling 9, the side of lighting fixture 1 facing ceiling 9 is referred to as the back side, and the side facing the floor surface from which light is emitted from light source 30 is referred to as the front side.

[0024] As shown in FIG. 7 , annular stepped portions 16A and 16B are formed around the outside of opening 13 on main body 10 along the circumferential direction. Inner stepped portion 16B forms the side of a truncated cone that is convex toward the front surface as a whole, and outer stepped portion 16A forms an annular flat surface portion 11 on the outer periphery of main body 10. In addition, an annular convex portion 18 that is convex toward the rear surface is formed between inner stepped portion 16B and outer stepped portion 16A. Light source 30 is placed within convex portion 18 and positioned by positioning portion 17. Light source 30 is screwed to main body 10 through a plurality of holes 15 and 20 drilled in flat surface portion 11 formed around main body 10 and flat surface portion 21 formed around opening 13.

[0025] As shown in FIG. 8, the back side of the main body 10 is formed with a bottom surface portion 12 (protruding portion 18) that protrudes toward the front, and a rim portion 19 is formed on the outermost periphery of the main body 10.

[0026] FIG. 9(A) is a side view of an LED light source cover 31 according to the embodiment, FIG. 9(B) is a plan view, and FIG. 9(C) is a perspective view.

[0027] The LED light source cover 31 is located on the front side of the light source 30, and is made of a diffusive material such as acrylic resin or polycarbonate resin, which eliminates the graininess caused by the light emitted from the LED 41 built into the light source 30 and mounted on the LED board (LED substrate) 40, and provides anti-glare properties, while also providing uniform illumination over a wide area.

[0028] As shown in Fig. 9(B), the LED light source cover 31 is an annular member having an opening 13 in the center. A flat plate portion 34 is formed around the opening 13 along the periphery of the opening 13. Two opposing holes 33 and an opening 39 for passing an electric wire for supplying power are formed in the flat plate portion 34, and a connection terminal 39A for connecting to the end of the electric wire is disposed inside the opening 39. A plurality of notches 37 and holes 38 are formed in an edge portion 32 on the outer periphery of the LED light source cover 31, and the LED light source cover 31 is fixed to the main body 10 by screws passing through the notches 37 and holes 38.

[0029] The shade 90 shown in FIG. 1 is removably attached so as to cover the entire front surface of the LED light source cover 31 and the main body 10. The shade 90 is made of a light-transmitting acrylic resin or polycarbonate resin with a diffusive property such as milky white, and is hollow and circular with an opening on one side. The shade 90 is also called a globe or the like, and has the function of efficiently diffusing the light emitted from the light source 30. A holding portion 14 is provided on the flat surface 11 of the main body 10, and the edge of the shade 90 engages with the holding portion 14 of the main body 10, thereby removably holding the shade 90 to the main body 10. As described above, the shade 90 is an optional component.

[0030] 10(A) is a side view of the 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 attachable battery 70. It has a circular annular portion 82 and cylindrical fastening bosses 83 with slightly tapered sides provided on the upper surface of the annular portion. The fastening bosses 83 are positioned opposite each other on the surface of the annular portion 82. A pair of legs 81 are fixed to the underside of the annular portion 82 adjacent to the hole 84 and perpendicular to the underside of the annular portion 82. The tips of the legs 81 are formed in an L-shape facing inward of the annular portion. In addition, a pair of notches 85 are formed in the annular portion 82.

[0032] By inserting and screwing 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, the battery holder 80, the LED light source cover 31, and the main body 10 are screwed together.

[0033] 11(A) is a side view of the 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-tiered shape consisting of a disk-shaped upper tier 77 and a disk-shaped lower tier 78 that is larger than upper tier 77. Upper tier 77 has two grooves 73 formed on its side surface, each facing the other. Groove 73 has a fitting portion 74 formed on the side surface of upper tier 77, with a recess that fits from the top to the bottom, and a fixing portion 75 recessed along the side surface. A protrusion 76 is formed between fitting portion 74 and fixing portion 75.

[0035] A pigtail cable 79 with a power terminal at its tip extends from the side of the upper section 77 of the battery 70. A USB terminal 71 and an indicator 72C that shows the usage status 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] 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 aligned with 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 portion 78 of the battery 70, and the battery 70 is rotated counterclockwise as viewed from above, whereby the tips of the legs 81 move along the fixing portion 75 of the battery 70, thereby fixing the battery 70 in place. The fixing portion 75 is provided with a protrusion 76, which fixes the legs 81 so that they do not come off the battery holder 80. To remove the battery 70 from the battery holder 80, the battery 70 can be easily removed by lifting it up and rotating it clockwise.

[0038] Furthermore, 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 mobile phones, etc. Furthermore, since the battery 70 is commercially available, it can be purchased at a low price, and it is possible to own multiple batteries as spares. By owning multiple batteries 70, lighting fixture 1 can be expected to stay lit for even longer, providing peace of mind in the event of a power outage.

[0039] 13(A) is a side view of the mounting adapter 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, 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, to connect mechanically and electrically to the commercial power source.

[0041] 1 and 14(A), the fixture 2 is a member for attaching the main body 10 to the installation location of the lighting fixture 1. The fixture 2 is also 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 fixture 2, and by pinching the release lever 4 with your 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, allowing the mounting adapter 3 to be removed from the 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 the main part.

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

[0045] 14(A) and 14(B) are both cross-sectional views of the lighting fixture 1 shown in FIG. 4 taken along line AA, showing the lighting fixture 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 inside 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 towards the front side of the lighting fixture 1.

[0047] Here, we will explain how to attach lighting fixture 1 to mounting fixture 2. First, attach mounting adapter 3 to mounting fixture 2. Next, hold main body 10 of lighting fixture 1 and insert mounting adapter 3 into opening 13 provided in main body 10. Then, lift main body 10 by pushing up tabs 5 of mounting adapter 3 from below, and tabs 5 are pushed into mounting adapter 3 by the edge of annular portion 82 of battery holder 80 attached to main body 10. If main body 10 is continued to be lifted in this state, tabs 5 will climb over the edge of annular portion 82 of battery holder 80 and will be positioned below annular portion 82. Because tabs 5 are biased outward from mounting adapter 3, they will again protrude outward and support main body 10 from below.

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

[0049] The LED substrate 40 is an annular flat plate with 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 at substantially equal intervals in an annular shape. The LEDs 41 are made up of warm white LEDs 42, daylight white LEDs 43, and firefly LEDs 44 (also called "afterglow LEDs"; "Firefly" (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, with the warm white LEDs 42 and the daylight white LEDs 43 alternately arranged in the same row. The LEDs 41 may be arranged in a single ring shape or in multiple ring shapes. The LEDs 41 may also be arranged in a grid pattern on the LED substrate 40. The warm white LEDs 42 and the daylight white LEDs 43 of 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 arranged in an appropriate location on the LED substrate 40, for example, around the opening or periphery of the LED substrate 40, or between the warm white LEDs 42 and the daylight white LEDs 43. As with the other drawings, in Fig. 14 and other figures, parts such as cords and connectors connected to the mounting adapter 3, the LED substrate 40, etc. are omitted with some exceptions.

[0052] FIG. 15 is a schematic diagram illustrating the circuit configuration of lighting fixture 1 according to an embodiment. Light source 30 has power supply board 50 arranged around opening 13. Power supply board 50 is equipped with dimming and color-adjusting power supply circuit 51, which functions as a normal power supply circuit for lighting fixture 1, and battery power supply circuit 60, which includes a power failure lighting circuit that charges battery 70 during normal operation and turns on lighting fixture 1 during a power failure. Dimming and color-adjusting power supply circuit 51 controls the applied voltage and current to adjust the brightness of light source 30, such as by turning it on / off or dimming it, and to adjust the color of light, such as by individually emitting the warm white LED 42 and the daylight white LED 43 or by emitting a mixed color of these LEDs. These dimming and color adjustment operations can be performed by operating 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 composed of a PFC circuit (power factor correction circuit) 61, a power supply circuit 62, a remote control light receiving circuit 63, and a power outage LED lighting circuit (boost circuit) 64. The battery 70 is composed 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 Act and certified by the Japan Lighting Manufacturers Association, use nickel-metal hydride (Ni-MH) batteries that comply with JIS standards. They do not require a control circuit and are inexpensive, but they do require a dedicated circuit for constant charging, have a short replacement guideline of four to 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 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 lifespan.

[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 commercially available general-purpose batteries, so it can be supplied to the market as an inexpensive lighting fixture despite having disaster prevention functions.

[0057] AC power supplied from the power supply passes through PFC circuit (power factor correction circuit) 52 and DC / DC circuit 53, then branches three ways and is connected to dimming / color-adjusting circuit 55, remote control light receiving circuit 54, and firefly lighting circuit 56. Command signals issued by button operations on remote controller 100 are received by remote control light receiving circuit 54, which then transmits the command signals to dimming / color-adjusting circuit 55, which controls dimming (on / off, dimming, etc.) and color adjustment (warm white, daylight, etc.), thereby controlling the output of LED circuit 40. Furthermore, when the power supply to LED circuit 40 is stopped by turning off lighting fixture 1, power is supplied from firefly lighting circuit 56 to firefly LED 44, causing firefly LED 44 to light up.

[0058] Meanwhile, 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 battery 70 through a power supply circuit 62. A pigtail cable 79 extending from battery 70 is connected to a connector (not shown) of power supply circuit 62, and DC power is supplied to battery main body 72A in battery 70. The output voltage of power supply circuit 62 is, for example, DC 24V.

[0059] Battery 70 comprises a battery main body 72A, a battery charging circuit 72B, and an indicator 72C. Indicator 72C is composed of three green LEDs located 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. While a green LED is used for indicator 72C, this is not limiting and other colored LEDs such as red or yellow may also be used.

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

[0061] Furthermore, 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 light on / off signal from the remote controller 100 to turn on / off the emergency light. For example, even if lighting fixture 1 is turned off and emergency light is activated due to a power outage or other reason, it may be daytime and the room is bright, making it unnecessary to turn on lighting fixture 1. In such cases, operating operation switches 101 and 102 on the remote controller 100 can be used to dim or turn off the emergency light of lighting fixture 1, thereby preventing unnecessary consumption of battery 70. This is particularly effective when the power outage lasts for a long period of time. Using an inexpensive, commercially available battery 70 can reduce the production cost of lighting fixture 1. Furthermore, because battery 70 can be easily removed from battery holder 80 of lighting fixture 1, a spare battery 70 can be prepared and fully charged in advance. By replacing the old battery 70 with a new one when it runs out, emergency light can be maintained for a long period of time.

[0063] Remote control light receiving circuits 54, 63 include a receiving unit (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 content of an instruction (control content for controlling lighting device 1) in response to 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 content. Remote controller 100 outputs an infrared signal indicating the control content for lighting device 1, for example, by outputting an infrared signal indicating an IR code corresponding to the operation content.

[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 configured with a light receiving element (for example, an infrared sensor) that can receive the infrared signal. The infrared signal received by the receiving section is converted into an electric signal and output to the dimming / color adjusting circuit 55 and the LED lighting circuit 64.

[0065] The dimming / color adjusting circuit 55 controls the warm white LED 42 and the daylight white LED 43 to perform dimming and color adjustment such as turning on / off and dimming in accordance with the electrical signal (for example, the control content indicated by the infrared signal) supplied from the receiving unit. Also, the LED lighting circuit 64 turns on / off the emergency lighting in accordance with the electrical 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 that the light source 30 should be turned 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 that the light source 30 should be turned 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 the type of dimming to be performed, and the color of the light source 30 is adjusted.

[0069] Wireless communication between the remote controller 100 and the receiving unit may use infrared signals, as well as 2.4 GHz specific low-power radio, 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. Upon receiving the power supply, the LED circuit 40 lights up the light source 30 using the DC power output from the battery 70, thereby starting emergency lighting.

[0071] In the event of an 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, just 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 it on. In other words, lighting fixture 1 can be turned on and off by operating dimmer switch 101. Lighting fixture 1 can also be operated using color adjustment switch 102 in the same way as in normal times.

[0072] For example, even in an emergency such as a power outage, if the light from lighting fixture 1 is not needed, such as during the day when the room is sufficiently bright, lighting fixture 1 can be turned off by operating operation switch 111 on remote controller 100, thereby saving power from battery 70 and preparing for lighting at night. Also, when needed, lighting fixture 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, but light source 30 may also be provided with an illuminance sensor that detects brightness and a human presence sensor that detects human movement. This allows for adding functions such as (1) not turning on the emergency light if 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 and extending the replacement interval of battery 70.

[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 functions 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 lit for a long period of time without the need for dedicated construction.

[0075] FIG. 16(A) shows a front view of wall switch cover 115. In a typical home, when lighting fixture 1 is turned off by operation switch 111, such as wall switch 110 used to turn lighting fixture 1 on and off, the LED lighting circuit 64 of lighting fixture 1 cannot detect a power outage. In other words, from the perspective of lighting fixture 1, the wall switch 110 has already caused the power outage, so even if a power outage occurs, battery power supply circuit 60 will not operate. Therefore, by covering wall switch 110 with wall switch cover 115, which prevents operation of wall switch 110, the present invention can be implemented in a simple manner without the user having to use wall switch 110 or performing wiring work, etc.

[0076] The wall switch cover 115 covers the entire wall switch 110 from above, and by attaching double-sided tape or adhesive to the side 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] 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 equipped 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 lights up for a certain period of time in emergencies such as when the power is turned on, by attaching a battery holder 80 to the lighting fixture 1 and positioning a battery in the battery holder 80 so that the lighting fixture 1 functions normally and as a disaster prevention light (emergency light) that lights up for a certain period of time in emergencies such as when the power is turned on.

[0079] Furthermore, the present invention can provide a lighting fixture 1 that 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, by attaching a battery 70 that can be attached to the lighting fixture 1, and that can be operated to turn the light on and off even in an emergency.
