[0009] The first embodiment will be described below with reference to Figures 1 to 6.

[0010] Figures 1 and 2 show the lighting device 10. The lighting device 10 is a round bracket-type emergency lighting fixture. The lighting device 10 is installed on the ceiling or wall surface, which is the surface to be installed.

[0011] The lighting device 10 comprises a housing 11, a light source unit 12, a terminal block 13, a power supply unit 14, an emergency unit 15, and a battery 16, all of which are arranged inside the housing 11.

[0012] The housing 11 comprises a fixture body 20 that is installed on the surface to be installed, and a globe 21 that is detachably attached to the fixture body 20.

[0013] As shown in Figures 2 to 6, the fixture body 20 has a circular mounting surface 22 and a circumferential surface 23 that rises from the periphery of the mounting surface 22, and is formed in a cylindrical shape with the opposite side from the mounting surface 22 open. The mounting surface 22 has a wiring hole 24 in the center through which a power line is inserted, and a pair of mounting holes 25 and a pair of mounting holes 26 are provided radially around this wiring hole 24. The pair of mounting holes 25 located on the inner diameter side are for screw fastening to the mounting surface, and the pair of mounting holes 26 located on the outer diameter side are for attaching suspension bolts.

[0014] On the inner surface of the mounting surface 22, a pair of cylindrical mounting parts 27 protrude at diagonal positions on either side of the central wiring hole 24 for mounting the light source unit 12. In addition, support parts 28 and 29 protrude in directions intersecting the direction connecting the pair of mounting parts 27 to support the back side of the light source unit 12.

[0015] On the inner surface of the mounting surface 22, a wall portion (projection) 30 protrudes in a direction intersecting the direction in which the mounting holes 25 and 26 are aligned, at a position midway between the central wiring hole 24 and the circumferential surface 23. The wall portion 30 is provided in a wide wall shape along the direction in which the mounting holes 25 and 26 are aligned. One support portion 28 is provided on one end of the wall portion 30 in the width direction. The wall portion 30 is provided with a lower projection height from the inner surface of the mounting surface 22 than the one support portion 28. The emergency unit 15 is arranged on the inner diameter side of the wall portion 30, and the battery 16 is arranged on the outer diameter side. The wall portion 30 has the function of supporting the emergency unit 15 and the function of positioning the battery 16. On the outer diameter side of the wall portion 30, a battery positioning portion 31 is provided to position the four sides around the battery 16. The wall portion 30 also serves as a battery positioning projection 31 to position one side of the battery 16.

[0016] On the inner peripheral surface of the peripheral surface 23, a threaded portion 32, which is a spiral female thread for rotating and attaching / detaching the glove 21 in the circumferential direction, is formed.

[0017] The glove 21 is constituted by, for example, an opal glove having light transmissivity and light diffusibility. The glove 21 has a circular front surface portion 33 and a peripheral surface portion 34 provided by rising from the peripheral portion of the front surface portion 33, and is formed in a cylindrical shape with the side opposite to the front surface portion 33 side being open. On the peripheral surface portion 34 of the glove 21, an insertion portion 35 to be inserted inside the instrument body 20 is formed, and around the insertion portion 35, a threaded portion 36, which is a spiral male thread that engages with the threaded portion 32 of the instrument body 20, is formed.

[0018] A disk-shaped packing 37 is arranged on the back side of the instrument body 20, and an annular packing 38 is interposed between the instrument body 20 and the glove 21, whereby the lighting device 10 having a waterproof structure is constituted.

[0019] Also, as shown in FIGS. 2 to 4, the light source unit 12 includes an annular light source 40, a substantially annular heat dissipation plate 41 to which the annular light source 40 is attached, a light source cover 42 that covers the annular light source between the annular light source 40 and the heat dissipation plate 41, and a light source connector 43 attached to the heat dissipation plate 41.

[0020] The annular light source 40 includes an annular substrate 44, and a plurality of normal light source elements 45 and a plurality of emergency light source elements 46 mounted on the substrate 44.

[0021] The substrate 44 has a substantially rectangular outer shape, and a substantially circular light source opening (substrate opening) 47 is formed inside. On the front side of the substrate 44, a first wiring pattern for mounting a plurality of normal light source elements 45 and connecting them in series or in series-parallel, and a second wiring pattern for mounting a plurality of emergency light source elements 46 and connecting them in series or in series-parallel are formed. On the substrate 44, a substrate connector 48 electrically connected to the first wiring pattern and the second wiring pattern is mounted. Then, the back side of the substrate 44 is arranged on the front side of the heat dissipation plate 41, and it is attached to the heat dissipation plate 41 with a plurality of screws 49.

[0022] Multiple commonly used light source elements 45 are composed of, for example, light-emitting diodes, mounted on the first wiring pattern of the substrate 44, and arranged in a ring shape on the outer periphery of the substrate 44.

[0023] Multiple emergency light source elements 46 are composed of, for example, light-emitting diodes, connected to a second wiring pattern on the substrate 44, and arranged in a ring shape on the inner circumference of the substrate 44, closer to the normal light source elements 45.

[0024] The regular light source element 45 and the emergency light source element 46 may be the same element or different elements, and the number of emergency light source elements 46 used is less than the number of regular light source elements 45.

[0025] The heat sink 41 is formed from a metal plate with a diameter smaller than the inner diameter of the peripheral surface 23 of the fixture body 20. The heat sink 41 has a circular outer shape, and a heat sink opening 50 smaller than the light source opening 47 is formed on the inside.

[0026] The edge of the heat sink opening 50 of the heat sink 41 is provided with a pair of dome-shaped mounting holes 51 facing the tip surfaces of a pair of mounting parts 27 that protrude from the fixture body 20. The light source unit 12 is attached to the fixture body 20 by screwing each screw 52 into each mounting part 27 through each mounting hole 51. The back side of the edge of the heat sink opening 50 of the heat sink 41 abuts against the tip surfaces of support parts 28, 29 that protrude from the fixture body 20. Therefore, the light source unit 12 is attached by the pair of mounting parts 27 and support parts 28, 29 in a state where it is positioned on the opening side of the fixture body 20, spaced apart from the inner surface of the mounting surface 22.

[0027] A connector mounting portion 41a for attaching a light source connector 43 is formed on the edge of the heat sink opening 50 of the heat sink 41, bent approximately vertically toward the front. The connector mounting portion 41a is bent so as to face the circumferential direction of the heat sink 41.

[0028] The heat sink 41 is provided with a light source cover mounting structure around the mounting position of the circuit board 44 for attaching the light source cover 42. In this light source cover mounting structure, a pair of hook holes 53 are provided on one side around the mounting position of the circuit board 44, screw holes 54 are provided on the other side opposite to the first side, and insertion holes 55 are provided on both sides that intersect with these first and second sides.

[0029] The light source cover 42 is a light-transmitting, for example, transparent cover, and is formed in an annular shape corresponding to the shape of the substrate 44. A pair of claws 56 are provided on one side of the light source cover 42 that are inserted into and hooked into the hooking holes 53 of the heat sink 41, a mounting piece 58 is provided on the other side opposite to the one side that is attached with a screw 57 to a screw hole 54, and insertion parts 59 are provided on both sides that intersect the one side and the other side that are inserted into insertion holes 55.

[0030] The light source connector 43 is attached to the connector mounting portion 41a of the heat sink 41 and is positioned inside the annular light source 40 when viewed from the front, and is positioned on the front portion 33 of the globe 21 in the light irradiation direction, relative to the annular light source 40. The connector connection surface on one end of the light source connector 43 is positioned facing the circumferential direction of the light source unit 12. A wire 60 is drawn out from the other end of the light source connector 43, and a connection connector 61 is connected to the tip of this wire 60. The connection connector 61 is connected to a board connector 48 mounted on the board 44.

[0031] Furthermore, as shown in Figures 2 and 5, the terminal block 13 is attached to the mounting surface 22 of the fixture body 20 at the wall portion 30 of the fixture body 20, the emergency unit 15, and the side of the battery 16. Power lines drawn in from the wiring holes 24 of the fixture body 20 are electrically connected to the terminal block 13. The power lines supply external power, such as commercial AC power.

[0032] Furthermore, the power supply unit 14 is mounted on the mounting surface 22 of the fixture body 20 in a position opposite the emergency unit 15 via the wiring hole 24. The input side of the power supply unit 14 is connected to the other end of the input wiring, one end of which is connected to the terminal block 13, and external power is input through the terminal block 13. The output side of the power supply unit 14 is connected to the other end of the normal output wiring, and the other end of this normal output wiring is connected to the fixture-side connector 65. The fixture-side connector 65 is detachably connected to the light source connector 43. The power supply unit 14 then converts the input external power into a predetermined lighting power such as DC power and supplies it to the normal light source element 45 of the annular light source 40, thereby lighting the normal light source element 45.

[0033] Furthermore, the emergency unit 15 is attached to the mounting surface 22 of the fixture body 20 at a position between the wiring hole 24 and the wall portion 30. The emergency unit 15 is formed in the shape of a long rectangular parallelepiped, with one end in the longitudinal direction attached to the mounting surface 22 of the fixture body 20. The other end in the longitudinal direction of the emergency unit 15 penetrates the inside of the annular light source 40 and is positioned on the front portion 33 of the globe 21 in the light irradiation direction, relative to the annular light source 40.

[0034] The emergency unit 15 comprises a case 70 and a circuit section housed within the case 70. The circuit section includes a charging circuit that charges the battery 16 when external power is input and discharges the battery 16 when there is a power outage, an emergency power supply circuit that converts power from the battery 16 into a predetermined emergency lighting power when there is a power outage, and an inspection circuit that executes an inspection mode in which the battery 16 and the light source unit 12 are inspected by an inspection signal from a remote control or by operating an inspection switch 74.

[0035] The emergency unit 15 includes an input terminal section 71 (shown in Figure 6) to which the other end of an input wiring, one end of which is connected to the terminal block 13, is connected; a connection connector 72 to which the battery 16 is connected; and an output terminal section 73 to which the annular light source 40 is connected. One end of the emergency output wiring is connected to the output terminal section 73, and the other end of this emergency output wiring is connected to the device-side connector 65. The normal output wiring is connected to the device-side connector 65 together with the emergency output wiring, and this device-side connector 65 is connected to the light source connector 43. In the event of a power outage, the emergency unit 15 supplies lighting power converted from the battery 16 to the emergency light source element 46 of the annular light source 40, thereby lighting the emergency light source element 46.

[0036] The emergency unit 15 is equipped with an inspection switch 74 for manually instructing inspection, a remote control receiver 75 for receiving signals such as inspection signals from a remote control, and a monitor lamp 76 for displaying the status of the battery 16 and light source unit 12 and the inspection results, on the front end surface facing the front portion 33 of the globe 21. These inspection switch 74, remote control receiver 75, and monitor lamp 76 are located on the front portion 33 side of the globe 21 in the direction of light irradiation, relative to the annular light source 40.

[0037] The emergency unit 15 is provided with a battery cord holder 77 on its side for holding the battery cord from the battery 16 inserted, and a battery connector holder 78 for temporarily holding the battery connector at the end of the battery cord. The battery cord holder 77 has a roughly L-shaped first holder 77a through which the battery cord is inserted between it and the side of the emergency unit 15, and a second holder 77b opposite the first holder 77a that presses the battery cord into the first holder 77a. The middle portion of the battery cord can be inserted through a notch between the first holder 77a and the second holder 77b and held by the battery cord holder 77. The battery connector holder 78 is provided on the mounting surface 22 side of the device body 20, closer to the battery cord holder 77, and holds the battery connector when it is inserted. These battery connector holders 78 and connection connectors 72 are positioned opposite the light source opening 47 inside the annular light source 40 and the heat sink opening 50 inside the heat sink 41.

[0038] Furthermore, the battery 16 uses a battery package in which multiple rechargeable secondary batteries are connected together. The battery 16 is positioned and arranged between the surrounding battery positioning parts 31 on the side of the wall part 30, and is detachably attached by a battery mounting member 82 which is attached to the battery positioning part 31 with decorative screws 81.

[0039] The battery 16 has a battery cord that is pulled out from the battery body, and a battery connector is connected to the end of this battery cord. The battery cord is inserted through the battery cord holder 77 of the emergency unit 15 and connected to the connection connector 72 of the emergency unit 15. At the time of factory shipment of the lighting device 10, in order to prevent the battery 16 from discharging, the battery connector is not connected to the connection connector 72, but is temporarily held in place by being inserted into the connector holder 78, and the battery connector is connected to the connection connector 72 when the lighting device 10 is installed.

[0040] To install the lighting device 10, the globe 21 and light source unit 12 are removed from the fixture body 20. The power wires, which are pulled out from the mounting surface, are routed into the fixture body 20 through the wiring hole 24, and the fixture is either screwed to the ceiling or wall using the mounting hole 25, or, if mounting to the ceiling, the mounting hole 26 is passed through the suspension bolts protruding from the ceiling surface, and the nuts screwed onto the suspension bolts are tightened to attach the fixture to the ceiling. The power wires routed into the fixture body 20 are connected to the terminal block 13.

[0041] The battery connector of the battery cord of battery 16 is detached from the battery connector holder 78 of the emergency unit 15 and connected to the connection connector 72 of the emergency unit 15. At this time, since the battery cord is held by the battery cord holder 77 of the emergency unit 15, even if the battery cord or battery connector is temporarily released from your hand during the connection work, the position of the battery connector will not shift significantly, allowing you to re-grasp it, and the battery cord will not get caught on other parts inside the main body 20, allowing you to connect it to the connection connector 72 of the emergency unit 15.

[0042] The light source unit 12 is inserted into the fixture body 20 and attached to the fixture body 20 with screws 52. When the light source unit 12 is attached to the fixture body 20, the battery connector holding part 78 and the connection connector 72 of the emergency unit 15 are positioned opposite the light source opening 47 on the inside of the annular light source 40 and the heat sink opening 50 on the inside of the heat sink 41. Therefore, even after attaching the light source unit 12 to the fixture body 20, the battery connector of the battery 16 can be connected to the connection connector 72 of the emergency unit 15 as described above.

[0043] The fixture-side connector 65 is pulled out from the light source opening 47 inside the annular light source 40 and the heat sink opening 50 inside the heat sink 41 to the front side of the light source unit 12 and connected to the light source connector 43. Since the light source connector 43 is attached to the connector mounting portion 41a of the heat sink 41 and is in a fixed position, it is easy to connect the fixture-side connector 65.

[0044] Attach the globe 21 to the fixture body 20, and the installation is complete.

[0045] When external power is supplied to the lighting device 10, the ignition power converted by the power supply unit 14 is supplied to the normal light source element 45 of the annular light source 40, causing the normal light source element 45 to light up. The light from the normal light source element 45 passes through the globe 21 and illuminates it. Because the normal light source element 45 is arranged in a ring and is located on the outer circumference of the annular light source 40, the entire globe 21 lights up evenly, and light is irradiated over a wide area.

[0046] The emergency unit 15 charges the battery 16 using external power.

[0047] Furthermore, if the supply of external power is interrupted due to a power outage or the like, the lighting device 10 will have its normal light source element 45 turn off and its emergency light source element 46 turn on.

[0048] The emergency unit 15 operates using power discharged from the battery 16 when external power is lost. The power from the battery 16 is converted into emergency lighting power and supplied to the emergency light source element 46 of the annular light source 40, causing the emergency light source element 46 to light up. Because the emergency light source elements 46 are arranged in an annular shape, the entire globe 21 lights up evenly, illuminating a wide area.

[0049] Furthermore, the emergency unit 15 displays the status of the battery 16 and the light source unit 12 using monitor lamps 76. For example, if the battery 16 is charging normally, the green monitor lamp 76 for the battery will light up, and if the light source unit 12 is functioning normally, the red monitor lamp 76 for the light source will turn off. On the other hand, if there is a problem with the battery 16 connection, the green monitor lamp 76 for the battery will turn off, and if a problem with the battery 16 charging or the battery 16 reaching the end of its lifespan is detected, the green monitor lamp 76 for the battery will blink, and if there is a problem with the light source unit 12, the red monitor lamp 76 for the light source will blink.

[0050] The illumination or flashing of the monitor lamp 76 can be seen through the front part 33 of the globe 21. Because the emergency unit 15 is positioned as part of the annular light source 40, and the monitor lamp 76 of the emergency unit 15 is positioned closer to the front part 33 of the globe 21 than the annular light source 40, it is easy to see the illumination or flashing of the monitor lamp 76 through the globe 21 even when the normal light source element 45 is illuminated.

[0051] Furthermore, during inspection, the remote control is operated towards the lighting device 10. When the remote control signal is received by the remote control receiver 75 of the emergency unit 15, the emergency unit 15 executes an inspection mode for the battery 16 and the light source unit 12. During the inspection mode, the green monitor lamp 76 for the battery and the red monitor lamp 76 for the light source flash alternately. The inspection results from the inspection mode are displayed by the illuminated state of the monitor lamps 76 as described above. Note that the inspection mode is also performed when the globe 21 is removed and the inspection switch 74 of the emergency unit 15 is operated.

[0052] To replace the battery 16, remove the globe 21, disconnect the fixture-side connector 65 from the light source connector 43, loosen the screw 52 securing the light source unit 12 to the fixture body 20, slide the light source unit 12 to the side to release the elliptical mounting hole 51 from the screw 52, ​​and remove the light source unit 12 from the fixture body 20 (resulting in the state shown in Figure 5). Furthermore, disconnect the battery connector from the connection connector 72 and the battery cord from the battery cord holder 77, loosen the decorative screw 81 to remove the battery mounting member 82, and remove the battery 16.

[0053] The new battery 16 to be replaced is placed between the battery positioning protrusions 31 on the fixture body 20, and the battery mounting member 82 attached to the battery 16 is attached to the fixture body 20 with decorative screws 81. The daruma-shaped mounting part 51 of the light source unit 12 is fitted onto the screw 52 on the fixture body 20 side, the light source unit is slid to the side, and the screw 52 is tightened to attach the light source unit 12 to the fixture body 20. The fixture-side connector 65 is connected to the light source connector 43, and the globe 21 is attached to the fixture body 20.

[0054] In the lighting device 10 configured as described above, the emergency unit 15 is positioned to penetrate the inside of the annular light source 40, allowing for effective use of the limited space inside the fixture and enabling miniaturization.

[0055] Furthermore, the regular light source elements 45 are arranged in a ring on the outer circumference of the annular light source 40, and the emergency light source elements 46 are arranged in a ring on the inner circumference. The emergency unit 15, which has a monitor lamp 76, is positioned inside the annular light source 40. As a result, the regular light source elements 45 and the monitor lamp 76 are positioned far apart, making it easier to see the light from the monitor lamp 76 even when the regular light source elements 45 are lit.

[0056] Furthermore, since the monitor lamp 76 is positioned closer to the front 33 side of the globe 21 than the annular light source 40, the light from the monitor lamp 76 can be made more visible.

[0057] Furthermore, since the emergency unit 15 is positioned inside the annular light source 40, and the light source side connector 43 is positioned opposite the emergency unit 15, the fixture side connector 65, which is drawn out through the light source opening 47 inside the annular light source 40, can be easily connected to the light source side connector 43, thereby improving the workability of the wiring.

[0058] Furthermore, since the emergency unit 15 has a connection connector 72 located opposite the front portion 33 of the globe 21, the battery connector of the battery 16 can be connected to the connection connector 72 without removing the light source unit 12 from the fixture body 20, even with the globe 21 removed.

[0059] Next, Figure 7 shows a second embodiment.

[0060] Figure 7 shows a bottom view of the lighting device 10 with the globe 21 and light source cover 42 removed.

[0061] The annular light source 40 has a protruding portion (light source protrusion) 90 that projects outwards from the inner light source opening 47. The protruding portion 90 is positioned opposite the emergency unit 15. Multiple emergency light source elements 46 are arranged together on the protruding portion 90.

[0062] Furthermore, the battery 16 is detachably positioned between the emergency unit 15 and the protrusion 90, facing the light source opening 47 inside the annular light source 40 and the heat sink opening 50 inside the heat sink 41.

[0063] The battery 16 is positioned in a wiring guide 91, which is placed with a gap between it and the wiring hole 24 for the power line to pass through, and is also positioned along the side of the emergency unit 15 and is detachably attached by a battery mounting member 92 which is attached to the main body of the device 20.

[0064] The battery mounting member 92 has a holder portion 93 that holds the battery 16 between itself and the wiring guide 91 and the emergency unit 15, and an arm portion 94 that extends from the holder portion 93 toward the mounting surface portion 22 of the fixture body 20, with the tip of the arm portion 94 being attached to the fixture body 20 by a screw 95. The screw 95 is positioned opposite the light source opening 47 inside the annular light source 40 and the heat sink opening 50 inside the heat sink 41, and is operable through the light source opening 47 inside the annular light source 40 and the heat sink opening 50 inside the heat sink 41.

[0065] The battery 16, together with the emergency unit 15, penetrates the inside of the annular light source 40, and a portion of the battery 16 may be positioned on the front 33 side of the globe 21 in the direction of light irradiation, relative to the annular light source 40.

[0066] Furthermore, in the lighting device 10 of this embodiment, since the emergency light source element 46 is arranged on the protruding portion 90 that protrudes inward from the annular light source 40, the light source opening 47 inside the annular light source 40 can be made larger in all areas except for the portion of the protruding portion 90, and the inside of the annular light source 40 can be effectively utilized.

[0067] Furthermore, since the battery 16 is detachably positioned inside the annular light source 40, the battery 16 can be easily replaced without removing the light source unit 12 from the fixture body 20.

[0068] Furthermore, the annular light source 40 includes those in which a portion of the annular shape is open, as long as at least the regular light source elements 45 are arranged in a ring shape and a light source aperture 47 is formed on the inside.

[0069] While several embodiments of the present invention have been described, these embodiments are presented as examples only and are not intended to limit the scope of the invention. These novel embodiments can be carried out in a variety of other forms, and various omissions, substitutions, and modifications can be made without departing from the spirit of the invention.
