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 and off by operating a wall switch or buttons on a remote controller (remote control) that comes with the lighting fixture.

[0003] When a natural disaster such as an earthquake or typhoon occurs, or when a malfunction in power generation equipment occurs and the commercial power supply is cut off, or when an overcurrent occurs in a home and the safety breaker trips and cuts off the power, a power outage occurs and lighting fixtures suddenly go out. Particularly when a power outage occurs at night, you will have to grope around in the darkness searching for light sources such as 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, thereby reducing their anxiety.

[0004] Therefore, as a measure against sudden power outages, lighting fixtures equipped with an emergency power supply that turns on in an emergency are known. When this lighting fixture detects a power outage, it lights up using power supplied from the emergency power supply, which is made up of a 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] In Patent Document 1, a lighting fixture is equipped with a battery, and when a power outage occurs while a remote control transmitter is connected to a power outlet, the remote control transmitter transmits a signal to turn on the lighting fixture using the battery, and the lighting fixture, which is made of a fluorescent lamp, is turned on by power supplied from the battery. However, this lighting fixture is a round ceiling light that uses a fluorescent lamp, which requires more power than light-emitting elements such as LEDs, so it consumes a lot of battery power and is limited to lighting for a relatively short period of time, and in order to ensure a certain level of lighting time, a large-capacity battery must be installed. Also, since no external remote controller is used other than the remote control transmitter plugged into the power outlet, operation of the lighting fixture is limited to the remote control transmitter, which has some issues.

[0007] Therefore, in order to solve the problems of the prior art documents, the present invention provides a lighting fixture that uses a light-emitting element such as an LED as a light source, and that is equipped with a power outage detection device with a power outage detection function, a receiving device installed in the lighting fixture, and a storage battery built into the lighting fixture, so that it functions as a lighting fixture in normal times and as a disaster prevention light that stays lit for a long time using power from the storage battery installed in the lighting fixture in a simple manner without the need for dedicated construction, and further provides a lighting fixture and its power outage detection device that can be operated, such as dimming the light source, from a remote controller regardless of whether it is normal time or an emergency. [Means for solving the problem]

[0008] In order to achieve the above object, the lighting fixture of the present invention comprises: The main unit is attached to the ceiling, a light source arranged on the front side of the main body and including a substrate on which a plurality of LEDs are mounted; a storage battery and a power supply device disposed in the main body; A power failure signal receiving unit that receives a power failure detection signal transmitted from a power failure detection device and transmits the power failure detection signal to the power supply device; a remote control signal processing unit that receives an operation signal transmitted from a remote controller and transmits an operation signal for the light source to the power supply device; A lighting fixture comprising: The power supply device is electrically connected to a commercial power source to supply power to the light source and the storage battery, Pairing with the power outage detection device is performed, supplying power from the storage battery to the light source based on the power failure detection signal; operating the light source based on the operation signal; It is characterized by: [Effects of the Invention]

[0009] According to the present invention, a storage battery is built into a lighting fixture that is attached to a mounting fixture (wiring device) installed on the ceiling (fixture mounting surface), and a receiving device installed in the lighting fixture receives a transmission signal sent from a power outage detection device installed in a power outlet during a power outage of the commercial power supply, etc., and during a power outage of the commercial power supply, etc., the lighting fixture is turned on using the DC output of the storage battery, allowing the lighting fixture to function as a disaster prevention light that can be lit for a long period of time.

DETAILED DESCRIPTION OF THE INVENTION

[0011] To facilitate understanding of the present invention, an example of a lighting fixture 1 according to an embodiment of the present invention will be described with reference to Figures 1 to 8. The lighting fixture 1 according to the embodiment of the present invention is generally called an LED ceiling light, and is a lighting fixture that is attached to an installation surface such as a ceiling 5 when in use.

[0012] It should be noted that the embodiment described below shows one specific example of the present invention, and therefore the arrangement, functions, numerical values, etc. of the components described in the embodiment are merely examples, and the scope of the present invention should not be interpreted in a limited manner by these. In addition, some components that make up the lighting fixture, such as wiring and screws, have been omitted to avoid complicating the drawing.

[0013] (Embodiment) FIG. 1 is a side view showing the entire lighting fixture 1 according to the embodiment.

[0014] In a typical home, a fixture (wiring device) 2 called a hook ceiling rosette, hook ceiling body, hook ceiling, hook rosette, etc. for attaching a lighting fixture such as a ceiling light is attached to an installation surface such as a ceiling 5. A hook metal fitting 137 provided on a dedicated mounting adapter 133 attached to the lighting fixture 1 is electrically and mechanically connected to the fixture 2, so that the lighting fixture 1 is attached to the installation surface such as the ceiling 5, and commercial power is supplied to the lighting fixture 1 through indoor wiring.

[0015] As shown in FIG. 1 , lighting fixture 1 according to this embodiment has a shade 90 on the front side of main body 10, similar to a typical ceiling light, so as to cover the entire front side of main body 10. Main body 10 is held to ceiling 5 by a fixture 2 provided on an installation surface such as ceiling 5, with hooks 137 of a mounting adapter 133 engaging with the fixture 2. Four rectangular parallelepiped abutment members 25 arranged on the ceiling surface side of main body 10 are located between main body 10 and ceiling 5 to keep main body 10 horizontal and stabilize it from wobbling, and are made of a flexible sponge-like material such as urethane foam. Here, when lighting fixture 1 is installed on ceiling 5, the side of lighting fixture 1 facing ceiling 5 is referred to as the back side, and the floor side from which light is emitted from light source 30 is referred to as the front side.

[0016] 2 is an exploded perspective view of the entire lighting fixture according to the embodiment. The figure shows lighting fixture 1, which is composed of, in order from the front side, shade 90, protective cover 31, lighting device cover 75, circuit board 40 mounted on the outer periphery of power supply unit 50 and storage battery 69, and main body 10 with contact members 25 arranged at four locations on the back side. An opening 13 is drilled in the center of main body 10 and protective cover 31, through which mounting adapter 133 is inserted and positioned.

[0017] FIG. 3A is a plan view showing a state in which shade 90 has been removed from lighting fixture 1 according to the embodiment, and FIG. 3B is a perspective view showing a state in which protective cover 31 has been further removed from the state shown in FIG. 3A.

[0018] 3A shows a substantially circular transparent protective cover 31 that covers the entire surface on which the substrate 40 is mounted. The protective cover 31 protects the mounting surface (live section) of the substrate 40 from accidentally coming into contact with fingers when the shade 90 is removed, and also serves to prevent foreign objects such as dust and insects from entering the interior.

[0019] As shown in FIG. 3A , protective cover 31 has outer peripheral edges 32 at three locations on the peripheral side of main body 10 and an inner peripheral edge 33 around central opening 13. Edges 32 and 33 contact flat surface 11 and edge 17 of main body 10, respectively, and are fixed to holes 15 of main body 10 by fastening means such as screws through six holes 34 and three holes 35. Protective cover 31 has approximately the same shape as lighting device cover 75 so as to cover lighting device cover 75 while maintaining a certain space between itself and circuit board 40, and has opening 36 of the same shape as central opening 13. The number of holes 34 and 35 and the fastening means for fastening protective cover 31 to main body 10 are arbitrary and are not limited to those described in the embodiment.

[0020] 3A and 3B, multiple U-shaped substrates 40 are arranged in the circumferential direction on the main body 10 to surround the central opening 13. The substrates 40 have multiple pairs of LEDs 41 and lenses 45 surface-mounted on their surfaces, and are referred to as light sources, light source modules, light source units, etc. A donut-shaped lighting device cover 75 is attached around the opening 13. An opening 80 in the lighting device cover 75 has approximately the same shape as the opening 13 of the main body 10. Here, the assembly of the substrates 40, i.e., the annular bottom surface 12 of the main body 10 on which the substrates 40 are mounted, is referred to as the light source 30.

[0021] 3C is a rear view of main body 10. Main body 10 has an opening 13 in the center and is made of a generally circular flat plate. On the back surface (rear side) of main body 10, a storage section (recess) 18 that protrudes toward the rear surface is formed around opening 13, and storage section 18 stores power supply unit 50 and storage battery 69 on the light irradiation surface side (front side).

[0022] Furthermore, indicator 51 is disposed on the side of edge 19 formed around main body 10. Indicator 51 is made of a light-emitting element such as an LED, and indicates the charge state and remaining battery power of storage battery 69 built into main body 10, as well as the status of communication with power outage detection device 150. Indicator 51 remains lit for a certain period of time after lighting fixture 1 is turned off to indicate the remaining battery power, etc. Note that indicator 51 may continue to display the remaining battery power, etc., even after lighting fixture 1 is turned off. Indicator 51 is not limited to being disposed on the side of edge 19 of main body 10, but may be disposed in any visible position within shade 90 of main body 10.

[0023] FIG. 3D is a schematic cross-sectional view of the main body 10 of the lighting fixture 1, with the upper side being the front (illumination surface) side. A ring-shaped edge 17 for fixing a mounting adapter 133 is formed around the central opening 13. A storage section 18 for a power supply unit 50 and the like is formed around the edge 17, and a ring-shaped bottom surface 12 is formed on the outside of the storage section 18 so as to be convex toward the front (illumination surface) side. A plurality of substrates 40 are disposed on the front surface of the bottom surface 12, and light sources 30 are formed thereon. In addition, a ring-shaped edge 19 is formed at the outermost periphery of the main body 10, extending along the periphery toward the front side. A flat surface 11 is located between the edge 19 and the bottom surface 12, and a holding section 14 for detachably fixing a shade 90 is disposed thereon.

[0024] FIG. 4A is a plan view showing the lighting fixture 1 according to the embodiment with the lighting device cover 75 removed. The power supply device 50, covered by a roughly crescent-shaped power supply cover 76, and the storage battery 69, consisting of two battery packs 70, are housed in a circular storage compartment 18 located on the outer periphery of the edge 17 surrounding the opening 13. The power supply cover 76 is provided on its surface with a hemispherical sensor cover 56 that covers the light receiving surface of the remote control light receiving sensor 55, a dome-shaped antenna cover 66, and a pairing switch 60 that is inserted into a circular hole 59 formed in the surface of the power supply cover 76. The power supply cover 76 is fixed to the main body 10 by a fastening means such as screws. The power supply cover 76 is made by molding a metal plate into a crescent shape, and the hemispherical sensor cover 56 and antenna cover 66 that are placed on the surface are both made of plastic.

[0025] Fig. 4B is a plan view showing the state from Fig. 4A with power supply cover 76 further removed, and Fig. 4C is a perspective view of the same. A remote control light receiving sensor 55 and an antenna 67 are arranged on the top of power supply device 50. Remote control light receiving sensor 55 is equipped with a remote control signal processing unit that processes an operation signal (infrared signal) for lighting device 1 transmitted from an external remote controller 100 and transmits an operation signal for light source 30 to power supply device 50. Antenna 67 is equipped with a power outage signal receiving unit that is connected to power supply device 50 and communicates with power outage detection device 150 via wireless signals. Pairing switch 60 is an activation switch that pairs lighting device 1 with power outage detection device 150 in a one-to-one (one and only) relationship.

[0026] The power supply device 50 is equipped with a power supply control unit that is conductive with the mounting adapter 133 and receives power from a commercial power source and converts the commercial power source into appropriate direct current; a light source processing unit that receives an operation signal that is an infrared signal transmitted from an external remote controller 100 and processed by a remote control signal processing unit, and controls the dimming of the light source 30; a battery control unit that controls the input and output of power to the storage battery 69; a power outage signal processing unit that receives a power outage detection signal transmitted from the power outage detection device 150 and transmits a signal to the light source processing unit and the storage battery control unit; a pairing processing unit that pairs the power outage detection device 150 and the power supply device 50 using a pairing signal from the power outage detection device 150; and an indicator control unit that controls an indicator 51 that displays the pairing connection status, the charging status of the storage battery, etc.

[0027] As shown in Figure 4C, each of the two battery packs 70 is composed of a pair of cylindrical dry cell-type rechargeable batteries 72. The battery packs 70 are connected in series, and terminals 73, 74 at both ends of the battery packs 70 are connected to the power supply unit 50. The power supply unit 50 supplies power to the storage battery 69 and stops supplying power when the battery is fully charged. The storage battery 69, which is made up of the two battery packs 70, waits in a fully charged state in preparation for a power outage.

[0028] 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, which comply with the JIS standard, as storage batteries. 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. For example, a lithium iron phosphate battery is used as the rechargeable battery 72. Among lithium ion batteries, this battery is characterized by its resistance to overcharging / overdischarging and its long life.

[0029] The continuous lighting time of light source 30 in lighting device 1 of the present invention is designed to last, for example, about 10 hours when the luminous flux of light source 30 is 800 lumens. Furthermore, if the luminous flux is reduced to about 150 to 500 lumens, continuous lighting for even longer periods can be expected. This luminous flux can be adjusted using operation switch 101 on remote controller 100.

[0030] Figure 5(A) is a plan view of a substrate 40 on which an LED 41 according to the embodiment is mounted, (B) is a side view of the same, (C) is a plan view showing two substrates 40 combined together, and (D) is a cross-sectional view of the main parts of (B).

[0031] 5(A) shows a plan view of a substantially U-shaped substrate 40 on whose surface LEDs 41 equipped with substantially hemispherical lenses 45 are mounted. In the embodiment, 16 LEDs 41 are mounted along the edge of each substrate 40. The substrate 40 is provided with holes 42 at three locations for passing through fastening members such as screws for fixing the substrate 40 to the main body 10.

[0032] Fig. 5(B) is a side view of the substrate 40 on which an LED 41 equipped with a lens 45 is mounted. An enlarged cross-sectional view of the part surrounded by a circle A in the figure is shown in Fig. 5(D).

[0033] 5(C), a center point 48 and three black dots 49 are provided on the surface of the substrate 40. The center point 48 is a mark for determining the mounting position of the LED 41 to be mounted on the surface of the substrate 40, and the black dots 49 are marks for adhesively fixing the legs 46 of the lens 45. The LED 41 is a surface mount (SMD) type and is soldered onto the center point 48 on the surface of the substrate 40, and the legs 46 of the lens 45 are adhesively fixed onto the black dots 49 on the surface of the substrate 40.

[0034] 5(C), two roughly U-shaped substrates can be created by cutting a roughly rectangular substrate into a roughly U-shape. By making the substrate 40 roughly U-shaped in this way, it is possible to cut out a large number of substrates 40 with minimal waste of raw materials. Furthermore, by placing the substrate 40 directly on the surface of the main body 10, it is easy to change the layout of the substrate 40 depending on the number of tatami mats and the amount of light required, and it is possible to respond immediately to demand. Furthermore, since the substrate 40 is in direct contact with the main body 10, heat generated from the substrate 40 can be efficiently dissipated through the main body 10.

[0035] 5(D) and (E) show that lens 45 has three legs 46 on its bottom surface, a hemispherical space 47 near the center of the bottom surface for LED 41 to fit in, and an inverted tapered recess at the top. The light emitted from LED 41 is diffused widely and evenly by the action of lens 45, which becomes thicker towards the periphery, thereby eliminating the graininess and glare that are characteristic of LEDs and providing uniform diffusion and anti-glare properties.

[0036] As shown in Figure 5(D), there is a small gap between the lens 45 drilled in the substrate 40 and the substrate 40, and the heat generated by the LED 41 dissipates through this gap, which, together with the heat dissipation from the lens 45 and the substrate 40, prevents the LED 41 from overheating.

[0037] Furthermore, the substrate 40 disposed as the light source 30 and the front surface (irradiation surface) of the main body 10 on which the substrate 40 is disposed are coated with white paint or the like. By coating the surface with white paint, the irradiated light emitted by the LED 41 can be efficiently reflected toward the front surface of the lighting fixture 1.

[0038] In the embodiment, 16 LEDs 41 are surface-mounted along the edge of each board 40, and 96 LEDs 41 are mounted on six boards 40 in total in the light source 30 of the lighting fixture 1. The number and arrangement of LEDs 41 mounted on one board 40, and the number and arrangement of boards 40 constituting the light source 30 can be changed as appropriate depending on the amount of light required for the object to be illuminated, the number of tatami mats, the purpose, etc.

[0039] Figure 6(A) is a top view of the power outage detection device 150 according to the embodiment, (B) is a front view of the same, (C) is a right side view of the same, (D) is a rear view of the same, and (E) is an oblique view of the power outage detection device 150 seen from above.

[0040] The power outage detection device 150 is installed by being plugged into a power outlet 121 provided on a wall or the like in a room, and constantly monitors for interruptions in the commercial power supply, etc. The power outage detection device 150 has a roughly rectangular box-shaped housing, and on the back side is provided a rod terminal (input terminal) 151 that is plugged into the power outlet 121 provided on a wall or the like to supply electricity. On the front side of the housing are provided a pairing button 155 for pairing with the lighting fixture 1 and an indicator 156 for displaying the active state. Also provided inside the housing are a signal control unit that detects a power outage due to an interruption in the commercial power supply and transmits a power outage detection signal, as well as pairing with the power supply device 50, and an indicator control unit that controls the display state of the indicator 156.

[0041] The indicator 156 displays, for example, a flashing red LED when pairing with the lighting fixture 1 is in a pairing standby state or disconnected state, a flashing yellow LED when pairing authentication is in progress, and a lit green LED when pairing connection with the lighting fixture 1 is in progress.

[0042] As shown in Figure 7, if a power outage occurs due to an earthquake or other reason cutting off the commercial power supply or other power source, the power supply to power outage detection device 150 installed in power outlet 121 is cut off. Power outage detection device 150 immediately transmits a power outage detection signal to antenna 67 of lighting fixture 1, and antenna 67 has a power outage signal receiving unit that receives the power outage detection signal transmitted from the power outage detection device, and the power outage signal receiving unit transmits the power outage detection signal to a power outage signal processing unit of power supply device 50. Upon receiving the power outage detection signal, the power outage signal processing unit transmits a signal to the light source processing unit and the storage battery control unit, power supply from storage battery 69 is started, and emergency lighting by light source 30 is started. The lighting state (emergency lighting) is maintained until a signal indicating restoration of commercial power is transmitted from power outage detection device 150.

[0043] Here, the pairing between the lighting fixture 1 and the power outage detection device 150 will be described. A pairing switch 60 is disposed on the top surface of the lighting device cover 75 of the main body 10 of the lighting fixture 1, and a push-button pairing button 155 is provided on the power outage detection device 150. Pairing is performed by pressing down the pairing button 155 on the power outage detection device 150 and then pressing the pairing switch 60 on the main body 10 of the lighting fixture 1. This causes the ID of the power outage detection device 150 to be sent to the lighting fixture 1, the ID is confirmed on the lighting fixture 1 side, and the ID of the lighting fixture 1 is returned to the power outage detection device 150. Next, after confirming with an indicator 156 on the power outage detection device 150 side that the ID of the lighting device 1 has been returned, the pairing button 155 is pressed down, and the IDs are mutually authenticated and stored, and one-to-one pairing authentication between the lighting fixture 1 and the power outage detection device 150 is established. Note that authentication for pairing may be performed in the reverse order to the above procedure, where lighting fixture 1 transmits a pairing signal to power outage detection device 150 and mutual authentication is performed.

[0044] Furthermore, lighting fixture 1 and power outage detection device 150 may be paired and connected in a one-to-one relationship beforehand at the time of product shipment. In this case, by installing lighting fixture 1 and plugging power outage detection device 150 into power outlet 121, the pairing connection is immediately established without the need to turn on power by pressing pairing switch 60 or the like on lighting fixture 1.

[0045] When the lighting fixture 1 and the power outage detection device 150 are paired, the lighting fixture 1 constantly transmits radio waves, for example, at intervals of about 3-4 times per minute, to confirm the pairing connection status. If there is no response from the power outage detection device 150, such as when the power outage detection device 150 is disconnected from the power outlet 121, the lighting fixture 1 determines that the pairing connection has been broken, and warns the user of an abnormality by, for example, flashing the LED of the indicator 51 installed on the lighting fixture 1. The abnormality warning may be issued by a buzzer or voice in addition to the display of the indicator 51. Furthermore, if the pairing connection has been broken even when the power outage detection device 150 is not disconnected from the power outlet 121, this can be confirmed by the abnormality indication displayed by the indicator 51 of the lighting fixture 1, as well as by the abnormality indication displayed by the indicator 156 of the power outage detection device 150.

[0046] Wireless communication between lighting fixture 1 and power outage detection device 150 uses a frequency band of 315 MHz to 1 GHz allocated to weak radio stations as defined by the Radio Law, but preferably uses a frequency band of 320 MHz or less, which allows the use of relatively strong radio waves.

[0047] The shade 90 shown in FIG. 1 is removably attached to cover the entire front surface of the main body 10, including the substrate 40 and the protective cover 31. The shade 90 is made of a light-transmitting acrylic resin or polycarbonate resin with diffusive properties, such as milky white, and is hollow and circular with an opening on one side. The shade 90 is also a component that has the function of efficiently diffusing light emitted from the light source 30, and is also called a globe, cover, or other name. A holding portion 14 is provided on the flat surface 11 of the main body 10, and the edge of the shade 90 (not shown) engages with the holding portion 14 of the main body 10, thereby removably holding the shade 90 to the main body 10.

[0048] 8 shows a mounting adapter 133, which is an attachment for mounting the main body 10 to the fixture 2 on the ceiling 5. The mounting adapter 133 is a substantially cylindrical member that has a pair of hooks 137 on its top surface, two claws 135 on each of its two side surfaces, and a pair of release levers 138, 139 on its bottom surface. The hooks 137 of the mounting adapter 133 fit into a pair of engagement grooves provided on the fixture 2 arranged on the ceiling 5 to provide a mechanical connection, and are also electrically connected to a commercial power source through a power cord 136.

[0049] The claws 135 are members for engaging the mounting adapter 133 with the edge 17 provided at the opening 13 of the lighting fixture 1 to fix the mounting adapter 133 to the main body 10. In addition, by pulling the pair of release levers 138, 139 together, the claws 135 can be retracted into the mounting adapter 133, and the mounting adapter 133 can be removed from the fixture 2.

[0050] Here, a method for attaching lighting fixture 1 to mounting fixture 2 will be described. First, mounting adapter 133 is attached to mounting fixture 2. Next, main body 10 of lighting fixture 1 is held and mounting adapter 133 is inserted into opening 13 provided in main body 10. Then, as main body 10 is lifted up by pushing up tabs 135 of mounting adapter 133 from below, tabs 135 are pushed into the interior of mounting adapter 133 by inner edge 17 provided on main body 10. If main body 10 is continued to be lifted in this state, tabs 135 will climb over edge 17 and will be positioned below edge 17. Because tabs 135 are biased outward from mounting adapter 133, they will protrude outward again and support main body 10 from below. Then, align the shade 90 with the mark (not shown) on the inside of the edge 17 of the main body 10, align the shade 90 with the inside of the main body 10, lift the shade 90 horizontally, press it tightly against the main body 10, and rotate the shade 90 to the right (clockwise) until you hear a clicking sound.This causes the locking portions (not shown) on the shade 90 to engage with the three holding portions 14 on the flat portion 11 of the main body 10, and the shade 90 is held to the main body 10.

[0051] To remove the main body 10 from the mounting adapter 133, first remove the shade 90 from the main body 10, and then use the release levers 138, 139 provided on the bottom surface of the mounting adapter 133. By placing your hands on the release levers 138, 139 and pulling them inward, the claws 135 retract into the mounting adapter 133, disengaging from the edge 17, and the main body 10 can be removed from the mounting adapter 133.

[0052] Lighting fixture 1 is normally turned on or off by turning the power on or off via wall switch 120 or by operating operation switch 101 on remote controller 100. Furthermore, dimming of light source 30, such as turning it on, off, dimming, or brightening, can be controlled by operating remote controller 100 in both normal and emergency situations. For example, if lighting fixture 1 is turned off due to a power outage or other reason and emergency lighting is initiated, it may be daytime and the room is bright, making it unnecessary to turn on lighting fixture 1. In such cases, light source 30 of lighting fixture 1 can be dimmed or turned off by operating operation switch 101 on remote controller 100, preventing unnecessary drain on storage battery 69 and preparing for nighttime lighting. This operation is particularly effective when the power outage lasts for a long period of time. Furthermore, the dimming function by operating remote controller 100 may be achieved by providing a dimmer switch (not shown) on main body 10 of lighting fixture 1 and dimming by operating the dimmer switch.

[0053] As shown in FIG. 7, remote controller 100 outputs an infrared signal indicating the command issued by the user (how lighting device 1 is to be controlled), and the signal is received by remote control light receiving sensor 55 of lighting device 1. 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 IR code corresponding to the control content, thereby outputting an infrared signal indicating the control content of lighting device 1. Remote controller 100 is provided with operation switch 101. Operation switch 101 is used to turn lighting device 1 on, off, dim, brighten, etc.

[0054] In lighting fixture 1 according to the embodiment, LEDs 41 mounted on light source 30 may be daylight white LEDs, warm white LEDs, daylight white LEDs, or the like, as appropriate. Alternatively, one of the warm white LEDs may be used as a night light, and a firefly LED (registered trademark) may also be provided. In this case, the warm white LEDs and daylight white LEDs are LEDs that emit warm white and daylight white light, respectively, and the firefly LED is an LED that lights up in green as an afterglow for a certain period of time, for example, for several minutes, after the LEDs in lighting fixture 1 are turned off. In the above case, warm white LEDs and daylight white LEDs are basically arranged alternately on the surface of substrate 40, but this alternating arrangement is not essential, and the arrangement can be adjusted as necessary. The firefly LED may be arranged in an appropriate location on substrate 40. Furthermore, a color adjustment switch (not shown) may be provided on the main body 10 of the lighting fixture 1 so that the color can be adjusted on the main body 10 side.

[0055] When implementing various types of LEDs as described above, the remote controller 100 is provided with an operation switch 101 for turning the lighting fixture 1 on, off, dimming, and brightening, as well as a color adjustment switch for adjusting the color, such as incandescent white, daylight white, and daylight, and a night light switch for turning the night light on and off, making it possible to control the dimming of the lighting color emitted by the light source 30.

[0056] Furthermore, by providing the remote controller 100 with a pairing operation button that instructs the lighting fixture 1 and the power outage detection device 150 to be paired and connected, the pairing connection can be made using the remote controller 100 without operating the pairing switch 60 of the lighting fixture 1 or the pairing button 155 of the power outage detection device 150.

[0057] Wireless communication between the remote controller 100 and the remote control light receiving sensor 55 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.

[0058] Furthermore, various sensors such as an illuminance sensor that detects brightness, a motion sensor that detects human movement, and a color sensor may be provided in the light source 30 of the lighting fixture 1. 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, (3) not turning on the light when no one is present, and (4) switching to night lighting when a futon or other item is laid out, thereby enabling efficient operation of the lighting fixture 1 including the storage battery 69, such as saving power to the storage battery 69 and extending the replacement interval.

[0059] The present invention is not limited to the above-described embodiment, and various modifications and applications of the above-described embodiment are possible.

[0060] In this way, the present invention provides a lighting fixture with a power outage detection function, such as a ceiling light that uses an LED as a light source.By arranging a storage battery and a power supply unit in the lighting fixture and equipping a power outage detection device in a power outlet to which commercial power is supplied, the lighting fixture functions in a simple manner, and also functions as a disaster prevention light (emergency light) that turns on for a certain period of time in emergencies such as power outages.
