[0008] One embodiment will be described below with reference to the drawings.

[0009] As shown in Figures 1 and 2, the lighting device 10 is a lighting device installed on a surface such as a ceiling. Furthermore, the lighting device 10 is an emergency lighting device that lights up using an emergency battery in the event of a power outage of the normal external power supply. Hereafter, the lighting device 10 will be described as being installed on a ceiling, with the front side in the direction of light irradiation being referred to as the lower side and the back side opposite to the direction of light irradiation being referred to as the upper side.

[0010] The lighting device 10 comprises a long fixture body 11, a long, normally operated light source unit 12 that is detachably fixed to one end of the fixture body 11 in the longitudinal direction, and a second light source unit 13 that is an emergency light unit fixed to the other end of the fixture body 11 in the longitudinal direction. The lighting device 10 is long and configured as a base light type in which the light-emitting area of ​​the first light source unit 12 is linear along the longitudinal direction.

[0011] Next, as shown in Figure 1, the first light source unit 12 is formed in an elongated shape and comprises a cylindrical cover 26, caps 27 provided at both ends of the cover 26, and mounting springs (not shown) that can engage with mounting brackets 103 of the fixture body 11. At least the protruding region 12b of the cover 26 is light-transmitting. Inside the cover 26 is a light source (not shown) comprising a chassis inserted and disposed inside the cover 26, and a regular light source module having a regular light source such as an LED, which is disposed on the lower side of the chassis.

[0012] The protruding region 12b of the cover 26 and cap 27 is a convex shape in which the cross-section in the width direction protrudes downward. It is formed in a curved shape.

[0013] On the other hand, the connection wire from the cap 27, which is connected to the regular light source unit, is electrically connected to the power line that is drawn into the fixture body 11.

[0014] The mounting springs are, for example, torsion springs and are provided at two locations near both ends in the longitudinal direction of the first light source unit 12. The mounting springs (not shown) are also detachably attached to the mounting brackets 103 of the fixture body 11, which will be described later. The mounting springs are configured to temporarily suspend the first light source unit 12 from the fixture body 11 by hooking them onto the mounting brackets 103 of the fixture body 11 while the unit is pulled up from the chassis, and then to attach the first light source unit 12 to the fixture body 11 by pushing it up, and to maintain that attached state.

[0015] As shown in Figures 1 to 3, the fixture main body 11 includes an elongated main body portion 17 and end plates 18 provided at both longitudinal ends of the main body portion 17. The main body portion 17 includes a bottom surface portion 19 that is the installation surface side facing the ceiling surface, opposite side surface portions 20 provided downward from both sides in the width direction, which is the short direction intersecting the longitudinal direction of the bottom surface portion 19, and reflection surface portions 21 provided to expand outward diagonally upward from the lower ends of the opposite side surface portions 20.

[0016] An opening 22 facing the bottom surface portion 19 is formed on the lower surface side between the opposite side surface portions 20 on the lower surface side of the fixture main body 11 and the end plates 18 at both ends, and a first recess 23 opening to the lower surface side is formed inside the fixture main body 11. The first light source unit 12 and the second light source unit 13 are arranged in the opening 22.

[0017] The fixture main body 11 is provided with a wiring hole 105 through which a power supply line for supplying AC power from a commercial AC power supply as an external power supply is inserted, and a plurality of mounting hole portions on the bottom surface portion 19 for mounting to the ceiling surface using suspension bolts, screws or the like. Further, as shown in Figure 4, the bottom surface portion 19 is formed with a notch 24 through which a flange portion 112 of a case 102 described later can be inserted. The flange portion 112 inserted through the notch 24 is located on the surface (back surface side) opposite to the bottom surface portion 19 of the fixture main body 11.

[0018] Further, as shown in Figures 2, 3 and 5, inside the fixture main body 11, a pair of mounting brackets 103, a terminal block 100 to which an external electric wire inserted through the wiring hole 105 is connected, a power supply unit 104 connected to the terminal block 100 for converting power supplied from the terminal block 100 and supplying the converted power to the first light source unit 12, an emergency battery 14, a protruding portion 101 protruding from the bottom surface portion 19 of the fixture main body 11 toward the opening 22, a case 102 detachably attached to the protruding portion 101 with the battery 14 placed thereon, and a fixture-side wiring holding portion 124 for holding a wiring portion 131 extending from the second light source unit 13 are mounted.

[0019] The mounting bracket 103 is a bracket to which the first light source unit 11 is attached, and is provided at two locations near both ends in the longitudinal direction of the bottom surface 19.

[0020] The wiring hole 105 is provided in a roughly circular shape on the longitudinal center side of the fixture body 11, through which the power cord is inserted from the outside and drawn into the fixture body 11.

[0021] The terminal block 100 has multiple connection holes and is positioned closer to the center of the fixture body 11 than the mounting brackets 103 which are located at both ends of the fixture body 11 in the longitudinal direction, and is located on one end of the fixture body 11 in the longitudinal direction relative to the wiring hole 105. Power lines inserted through the wiring hole 105 are connected to it and it is fixed to the bottom surface 19 of the fixture body 11 with screws or the like.

[0022] The terminal block 100 may be located closer to the center of the fixture body 11 than the mounting brackets 103 which are located at both ends of the fixture body 11 in the longitudinal direction, and on the other end of the fixture body 11 in the longitudinal direction relative to the wiring hole 105.

[0023] In a front view from below, the power supply unit 104 is fixed with screws or the like to the other end in the longitudinal direction, on the opposite side of the terminal block 100 from the wiring hole 105. The power supply unit 104 is also connected to the terminal block 100 via wires (not shown), and converts the power supplied from the terminal block 100 to supply power to the first light source unit 12.

[0024] The power supply unit 104 may be positioned in the same direction as the terminal block 100 with respect to the wiring hole 105 when viewed from below.

[0025] The battery 14 consists of two batteries, for example, a first battery 14a and a second battery 14b, and is positioned on the central side of the device body 11 from the mounting bracket 103 and on one end of the device body 11 in the longitudinal direction from the terminal block 100.

[0026] The battery 14 is a rechargeable secondary battery, such as a nickel-metal hydride battery or a lithium-ion battery. The battery 14 also has a battery connection line 15 equipped with a connector (not shown) that can be connected to a connection part 132, which is a connector provided at the end of a wiring 131 extending from the power supply unit 33 of the second light source unit 13 (described later). Under normal circumstances, the battery 14 is charged with power supplied from the power supply unit 33, and in emergencies such as power outages, the battery 14 supplies power to the power supply unit 33. At this time, the power supply unit 33 uses the power supplied from the battery 14 to light up the second light source unit 13. The shape of the battery 14 is preferably a curved shape such as an ellipse, but is not limited thereto.

[0027] As shown in Figures 6 and 7, the protrusion 101 is positioned at one end of the fixture body 11, relative to its longitudinal center. One end of the protrusion 101 is fixed to the bottom surface 19 with a screw or the like, and the other end protrudes toward the opening 22 of the fixture body 11. The protrusion 101 has a support column 200 extending from one end and a screw hole 201 provided at the other end. The case 102 is attached to the screw hole 201 at the other end via a fixing member 110 such as a screw.

[0028] As shown in Figures 6 to 8, the case 102 includes a plate-shaped mounting portion 106 extending in the longitudinal direction of the fixture body 11, side plate portions 107 rising from both ends of the mounting portion 106 in the longitudinal direction toward the fixture body 11, guide plate portions 111 rising from both ends of the mounting portion 106 in the short direction toward the fixture body 11, and a plate-shaped mounting portion 108 projecting from one end of the mounting portion 106 in the longitudinal direction toward the other end of the fixture body 11 in the longitudinal direction. The mounting portion 108 has a mounting hole 109 through which a part of the fixing member 110 (for example, the portion of a wing bolt with spirally arranged threads) is inserted. The side plate portion 107 rising toward the fixture body 11 has a flange portion 112 extending toward one end of the fixture body 11 in the longitudinal direction, and the flange portion 112 is inserted by sliding from an oblique direction into a notch portion 24 formed in the bottom surface portion 19 of the fixture body 11. Furthermore, it is preferable that the longitudinal dimension of the flange portion 112 extending to one end of the fixture body 11 in the longitudinal direction is longer than the longitudinal dimension of the notch portion 24 formed in the longitudinal direction of the fixture body 11.

[0029] Furthermore, the mounting section 106 has a first surface 140 on the side facing the main body 11 and a second surface 141 on the side facing the first light source unit 12, and the first battery 14a and the second battery 14b are mounted on the first surface 140. The first battery 14a and the second battery 14b have curved surfaces 36, and a gap 123 is provided between the first battery 14a and the second battery 14b due to the mutual curved surfaces 36 of adjacent first batteries 14a and second batteries 14b.

[0030] Furthermore, when the battery 14 is placed on the first surface 140 of the mounting portion 106, the length X from one end to the other of the protruding portion 101 is longer than the length Y (thickness of the battery 14) from the surface facing the bottom surface 19 of the battery 14 to the surface facing the first surface 140 of the mounting portion 106. In other words, the vertical length X of the protruding portion 101 is longer than the vertical length Y of the battery 14.

[0031] Furthermore, the length Z from the end of the side plate portion 107 on the mounting portion 106 side to the flange portion 112 is longer than the length Y from the surface facing the bottom surface portion 19 of the battery 14 to the surface facing the first surface 140 of the mounting portion 106. In other words, the vertical length Z of the side plate portion 107 is longer than the vertical length Y of the battery 14.

[0032] The case 102 is attached to the device body 11 by inserting the flange portion 112 into the notch portion 24 with the first battery 14a and the second battery 14b placed inside, and then screwing the fixing member 110, which is inserted through the mounting hole 109, into the screw hole 201 of the support column portion 200.

[0033] The other end of the support column 200 is not limited to the screw hole 201; for example, it may have a screw thread. In this case, the fixing member 110 is, for example, a wing nut, and the mounting hole 109 is inserted through the screw thread of the support column 200, and the case 102 is attached by the fixing member 110. The mounting hole 109 may be a round hole or an elongated hole.

[0034] The wiring holding portion 120 is provided in the center of the case 102. The wiring holding portion 120 includes a pin portion 125 that is inserted through a hole 25 provided in the center of the case 102, a first return portion 126 that unfolds so as to open when one end of the pin portion 125 is inserted through the hole 25, a second return portion 127 provided on the other end of the pin portion 125, and a binding portion 121 provided on the other end of the pin portion 125. The binding portion 121 holds the wiring portion 131 and the connection portion 132 when the wiring portion 131 extending from the second light source unit 13 is inserted into the binding portion 121. The shape of the binding portion 121 of the wiring holding portion 120 may be a clip shape or the like. Furthermore, the means for holding the wiring section 131 with the wiring holding section 120 is not limited to a means of inserting the wiring section 131 through the binding section 121, but may also be a means of bundling and holding the wiring section 131, such as a cable tie, or a means of bundling the wiring section 131 with hook-and-loop fasteners, etc. The connecting section 132 is, for example, a connector, and it is preferable that the size of the insertion hole (loop) of the binding section 121 in the wiring holding section 120 is smaller than the connecting section 132. With this configuration, the connecting section 132 catches on the binding section 120, preventing the wiring section 131 from coming off the case 102.

[0035] Here, the holding of the wiring section 131 by the wiring holding section 120 means, for example, that the wiring section 131 may be fixed in place, or that the wiring section 131 may be caught in the insertion hole of the binding section 121. In other words, it is sufficient that the wiring section 131 does not fall out of the wiring holding section 120.

[0036] Furthermore, the wiring holding portion 120 is positioned on the first light source unit 12 side of the case 102. That is, it is provided on the back side of the mounting portion 106 of the case 102. Also, when the first battery 14a and the second battery 14b are mounted on the case 102, the wiring holding portion 120 is positioned between the adjacent first battery 14a and the second battery 14b. In addition, an air gap 123 is provided between the adjacent first battery 14a and the second battery 14b, and the pin portion 125 of the wiring holding portion 120 is located in the air gap 123.

[0037] As shown in Figures 5, 6, and 9, the device-side wiring retaining parts 124 are provided in multiple locations on the side surface 20 of the device body 11. The device-side wiring retaining parts 124 have the same configuration as the wiring retaining parts 120 and include a pin portion 125 that is inserted into a hole 16 provided in the side surface 20 of the device body 11, a first return portion 126 that unfolds so as to open with one end of the pin portion 125 inserted into the hole 25, a second return portion 127 provided on the other end of the pin portion 125, and a binding portion 121 provided on the other end of the pin portion 125. The wiring portion 131 is inserted into the binding portion 121 and held inside the device body 11. The first return portion 126 of the device-side wiring retaining part 124 is located in the space between the back surface of the side surface 20 of the device body 11 and the back surface of the reflective surface portion 21. The wiring retaining portion 124 on the fixture body side may be provided on the bottom surface 19 of the fixture body 11. Although the wiring retaining portion 124 on the fixture side has been described as having the same configuration as the wiring retaining portion 120, it is not limited to this configuration; any device that can be attached to the fixture body and hold the wiring portion 131 is acceptable, and it may have a different structure from the wiring retaining portion 120.

[0038] Next, Figures 10 and 11 show the second light source unit 13. The second light source unit 13 comprises a housing 30, an emergency light source 31 fixed to the housing 30, a lens 32 facing the emergency light source 31, a power supply unit 33 which is an emergency lighting unit housed inside the housing 30, and a decorative frame 35 fixed to the housing 30. The longitudinal length of the fixture body 11 is shorter than that of the first light source unit 12. The housing 30 is integrally formed, for example, from die-cast aluminum. The housing 30 has a substantially rectangular opening 37 on its lower side, with a second recess 38 formed inside that opens on the lower side, and a flange 39 protruding from the lower end periphery. Holes 42 and 43 for attaching the decorative frame 35 with screws are provided in the flange 39 on one end (the side with the first light source unit 12) and the other end (the side opposite to the first light source unit 12). The part of the housing 30 above the flange 39 is inserted into the first recess 23 of the fixture body 11.

[0039] The housing 30 is provided with a box-shaped housing 44 that protrudes upward and houses the power supply unit 33 inside. An emergency light source arrangement section 46 is provided on the lower side of this housing 44, with an emergency light source 31 positioned at one end (the side of the first light source unit 12).

[0040] The housing section 44 is provided in a box shape that protrudes upward, and a second recess 38 for housing the power supply unit 33 is formed inside. On one end of the housing section 44, on one side in the width direction, a wiring base section 48 is provided that protrudes upward from the upper surface side of the protruding section 45. The upper surface of the wiring base section 48 is located at an intermediate height in the vertical direction of the housing section 44, and a wire insertion hole 49 is provided on the upper surface of the wiring base section 48, with the inside of the wiring base section 48 communicating with the housing section 44. A wiring section 131, which is a battery connection wire drawn out from the power supply unit 33, and a power supply connection wire extended from the terminal block 100 are inserted through the wire insertion hole 49. The power supply connection wire is electrically connected to the power supply unit 33, and the wiring section 131, which is a battery connection wire, is electrically connected to a connection section 132 provided at the tip of the wiring section 131 and to battery connection wires 15 drawn out from the first battery 14a and the second battery 14b.

[0041] The wiring section 131 is held by a plurality of wiring retaining sections 120 provided on the side of the fixture body 11, and the connection section 132 at the end of the wiring section 131 is held by a wiring retaining section 120 attached to the case 102. The wiring section 131, when held by the wiring retaining sections 120, is located on the fixture body 11 side of the opening 22 of the fixture body 11.

[0042] Furthermore, the emergency light source 31 uses a light-emitting module on which semiconductor light-emitting elements such as LEDs or organic ELs are mounted on a substrate. The emergency light source 31 is combined with an annular socket 58 and fixed to the emergency light source distribution section 46 by the socket 58. The emergency light source 31 is thermally connected to the emergency light source distribution section 46, and the heat generated when it is lit is dissipated to the housing 30.

[0043] The socket 58 is attached to the emergency light source distribution section 46 by screws or the like, with the emergency light source 31 sandwiched between the socket 58 and the emergency light source distribution section 46. The socket 58 is electrically connected to the emergency light source 31, and the wiring from the power supply unit 33 is also electrically connected to the socket 58, thereby electrically connecting the emergency light source 31 and the power supply unit 33.

[0044] Furthermore, the lens 32 is formed in the shape of a convex lens that protrudes in the direction of light irradiation, and is positioned opposite the emergency light source 31, receiving light emitted from the emergency light source 31 and emitting it in a predetermined light distribution. The lens 32 is fitted around the socket 58 and positioned relative to the emergency light source 31, and the decorative frame 35 is placed thereon.

[0045] Furthermore, the power supply unit 33 is inserted into the housing section 44 through the opening 37 of the housing 30 and is held and housed between the upper surface of the housing section 44 and the decorative frame 35 that closes the opening 37 of the housing 30.

[0046] The power supply unit 33 comprises a resin case 60 and a circuit unit (not shown) housed within the case 60. The circuit unit includes a charging circuit that converts external power into a predetermined charging power to charge the battery 14 when AC power is supplied, and an emergency lighting circuit that converts the battery power stored in the battery 14 into a predetermined lighting power and supplies it to the emergency light source 31 to light it during a power outage. The aforementioned power supply connection wires and battery connection wires are connected to the circuit unit, and these power supply connection wires and battery connection wires are inserted through wire insertion holes 49 and brought out to the outside of the housing 30. The emergency lighting circuit of the circuit unit and the emergency light source 31 are electrically connected by wiring.

[0047] The circuit section (not shown) is equipped with an inspection unit 62 for checking the lifespan of the battery 14 and for any abnormalities in the emergency light source 31. The inspection unit 62 is located on the underside of the power supply unit 33. The inspection unit 62 includes a receiving unit for receiving wireless signals such as infrared signals transmitted from an external terminal such as a remote control, a transmitting unit for transmitting inspection results to the external terminal, an inspection switch unit 63 for manually instructing the inspection, and a monitor lamp for displaying inspection results, etc.

[0048] Furthermore, the decorative frame 35 has a surface portion 68 on its front side that is formed in a convex curved shape with a cross section in the width direction that protrudes downward, so as to be continuous with the surface shape of the protruding region 12b of the first light source unit 12.

[0049] The back side of the surface portion 68 of the decorative frame 35 is formed in a concave shape, and the lower side of the housing 30 is positioned there via a packing 34. The surface portion 68 of the decorative frame 35 is attached to the holes 42 and 43 of the housing 30 with screws.

[0050] The surface portion 68 of the decorative frame 35 is provided with a light source window 69 in which the emergency light source 31 faces and the central part of the lens 32 protrudes, and an inspection window 70 in which the inspection section 62 faces.

[0051] Then, the second light source unit 13 is fixed to the fixture body 11 by screwing a screw that passes through the bottom portion 19 into the housing 30, with the housing 30 inserted into the first recess 23 of the fixture body 11 and the upper surface of the housing 44 in contact with the lower surface of the bottom portion 19 of the fixture body 11.

[0052] Next, the operation of the lighting device 10 will be explained.

[0053] The second light source unit 13 is fixed to the fixture body 11, and power supply connection wires drawn from the terminal block 100 are inserted through the wire insertion holes 49 of the second light source unit 13 and electrically connected. In addition, the wiring section 131, which is a battery connection wire drawn from the power insertion holes 49 of the second light source unit 13, is electrically connected to the battery connection wires 15 of the first battery 14a and the second battery 14b.

[0054] The first battery 14a and the second battery 14b, which are electrically connected to the second light source unit 13, are placed on the mounting portion 106 of the case 102, and are positioned between the fixture body 11 and the case 102 with the case 102 and the protruding portion 101 engaged.

[0055] When AC power is supplied to the lighting device 10 from an external source, the AC power is supplied via the terminal block 100 to the power supply unit 104 of the first light source unit 12 and to the power supply unit 33 of the second light source unit 13. In the first light source unit 12, the power supply unit 104 converts the AC power into a predetermined lighting power and supplies it to the light source, causing the light source to light up. In the second light source unit 13, the charging circuit of the power supply unit 33 converts the AC power into a predetermined charging power and charges the battery 14.

[0056] Furthermore, if a power outage occurs and AC power is no longer supplied to the lighting device 10 from an external source, the first light source unit 12 will turn off. The second light source unit 13 operates using the power discharged from the first battery 14a and the second battery 14b, converting the power from the first battery 14a and the second battery 14b into a predetermined lighting power and supplying it to the emergency light source 31, which will then light up.

[0057] Furthermore, when inspecting the second light source unit 13, the operator uses a remote control to send an inspection signal to the inspection unit 62 of the second light source unit 13. When the power supply unit 33 of the second light source unit 13 receives the inspection signal to the inspection unit 62, it enters inspection mode and uses the power of the first battery 14a and the second battery 14b to illuminate the emergency light source 31 for a predetermined inspection period, determining the status of the emergency light source 31 and the lifespan of the first battery 14a and the second battery 14b. The inspection operation and inspection results are displayed on the monitor lamp of the inspection unit 62. The operator can then visually check the monitor lamp of the inspection unit 62 to confirm the inspection results or check the inspection results received on the remote control. Note that the inspection operation of the second light source unit 13 can also be performed by operating the inspection switch unit 63.

[0058] Next, we will explain the procedure for replacing battery 14.

[0059] First, the first light source unit 12 is pulled down from the fixture body 11 installed on the ceiling, the mounting spring is hooked onto the mounting bracket 103 to temporarily suspend the first light source unit 12, and the connector connection between the first light source unit 12 and the power supply unit 104 is disconnected.

[0060] Next, the first light source unit 12 is removed from the fixture body 11.

[0061] Next, the battery connection wires 15 of the first battery 14a and the second battery 14b, which are connected to the wiring section 131 of the power supply unit 33 of the second light source unit 13, are removed from the wiring section 131, which is the battery connection wire. At this time, the wiring section 121 is maintained in a state where it is held by a plurality of fixture-side wiring holding sections 124 provided on the fixture body 11 and by the wiring holding section 120 of the case 102.

[0062] Next, remove the fixing member 110, such as a screw, that secures the screw hole 201 of the protruding part 101 to the mounting hole 109 of the case 102.

[0063] Next, as shown in Figure 8, adjust the angle so that the mounting hole 109 side of the case 102 is oblique to the fixture body 11. In other words, tilt the mounting hole 109 side of the case 102 toward the irradiation surface.

[0064] Next, the flange portion 112 of case 102 is slid out of the notch portion 24 of the fixture body 11, and the first battery 14a and the second battery 14b are removed together with case 102, and the new first battery 14a and the second battery 14b are placed on the mounting portion 106 of case 102. Then, with the first battery 14a and the second battery 14b placed on the mounting portion 106, the flange portion 112 of case 102 is tilted diagonally relative to the fixture body 11, and the flange portion 112 is slid into the notch portion 24. At this time, since case 102 has a guide plate portion 111 and a side plate portion 107 on the mounting portion 108 side, the batteries 14 can be attached to the fixture body 11 without slipping out of case 102 even when tilted diagonally.

[0065] Next, the screw hole 201 on the other end of the protruding part 101 is aligned with the mounting hole 109 provided in the mounting part 108 of the case 102.

[0066] Next, a fixing member 110 such as a screw is attached to the mounting hole 109 of the case 102 and the screw hole 201 of the protrusion 101, thereby fixing the case 102 and the protrusion 101 together.

[0067] Next, the connection part 132 of the wiring section 131, which is the battery connection wire of the power supply unit 33 attached to the wiring holding section 120 provided in the case 102, is connected to the battery connection wires 15 of the first battery 14a and the second battery 14b.

[0068] Next, the mounting spring of the first light source unit 12 is hooked onto the mounting bracket 103 of the fixture body 11, putting it into a temporary suspension state.

[0069] Next, the first light source unit 12 and the power supply unit 104 are connected by wiring.

[0070] Finally, the first light source unit 12 is pushed up onto the fixture body 11, completing the replacement of the first battery 14a and the second battery 14b.

[0071] In the lighting device 10 configured as described above, the wiring section 131 extending from the power supply unit 33 of the second light source unit 13 is held by the fixture-side wiring holder 124 provided on the side portion 20 of the fixture body 11 and the wiring holder 120 provided on the case 102, allowing for the replacement of the first battery 14a and the second battery 14b. Therefore, the wiring section 131 does not hang down and does not interfere with the work when replacing the batteries. In addition, when the case 102 containing the new first battery 14a and the second battery 14b is attached to the fixture body 11, the wiring section 131 is held by the case 102, making it easy to connect the battery connection wire 15 to the connection portion 132 of the wiring section 131. Furthermore, since the wiring section 131 is held by the wiring holding section 120 of the case 102, sagging of the wiring section 131 is prevented, and the wiring section 131 is prevented from being pinched between the first light source unit 12 and the fixture body 11 when the first light source unit 12 is attached to the fixture body 11.

[0072] Furthermore, since the case 102 is fitted with a wiring holder 120 that holds the wiring section 131 and the connection section 132, even if the worker accidentally lets go of the case 102 when removing it from the main body 11 of the device, the case 102 will remain suspended in mid-air and will not fall.

[0073] Furthermore, since the wiring holding section 120 is positioned in the center of the second surface 141 side of the mounting section 106 of the case 102, and the wiring section 131 and connection section 132 extending from the power supply section 33 are held in this wiring holding section 120, the lengths from the first battery 14a and the second battery 14b to the connection section 132 become approximately equal. Therefore, there is no need to prepare batteries with connection wires of different lengths, and wiring work can be performed by preparing only one type of battery with connection wires of equal length. In addition, since there is no need to manufacture batteries with connection wires of different lengths, manufacturing costs are reduced.

[0074] Furthermore, when the first battery 14a and the second battery 14b, each having a curved surface 36, are placed on the mounting portion 106 of the case 102, and the wiring holding portion 120 is positioned in the center of the second surface 141 of the mounting portion 106 of the case 102, the first return portion 126 of the wiring holding portion 120, which is provided on the first surface 140 of the mounting portion 106 of the case 102, is located between the wiring holding portion 120 and the gap 123 provided by the curved surfaces 36 of the first battery 14a and the second battery 14b. As a result, the wiring holding portion 120 does not interfere with the first battery 14a and the second battery 14b, and multiple batteries can be mounted in the limited space of the mounting portion 106.

[0075] Since the flange portion 112 of case 102 is longer in the longitudinal direction of the fixture body 11 than the notch portion 24 of the fixture body 11, even if the fixing member 110 that fixes the protruding portion 101 of the fixture body 11 and the mounting portion 108 of case 102 comes off, the flange portion 112 will catch on the notch portion 24, preventing case 102 from falling.

[0076] Furthermore, since the flange portion 112 of the case 102 is inserted into the notch portion 24 of the fixture body 11, the first battery 14a and the second battery 14b can be replaced by tilting the case 102 toward the opening 22 of the fixture body 11, eliminating the need to remove the case 102 from the fixture body 11, thus improving work efficiency.

[0077] Furthermore, since the case 102, on which the first battery 14a and the second battery 14b are placed, is fixed via a fixing member 110 to the other end of the protrusion 101 that extends from the bottom surface 19 of the device body 11 toward the opening 22, the first battery 14a and the second battery 14b can be replaced by working near the opening 22. As a result, as in the conventional method, the worker does not need to reach the bottom surface 19 of the device body 11 with their hands or tools such as a screwdriver when replacing the first battery 14a and the second battery 14b, making the replacement work easier.

[0078] Furthermore, when replacing the first battery 14a and the second battery 14b, tilting the case 102 toward the opening 22 brings the first battery 14a and the second battery 14b even closer to the opening 22. As a result, when replacing the first battery 14a and the second battery 14b, the worker does not need to reach deeply into the first recess 23 of the device body 11, improving work efficiency.

[0079] Furthermore, when the first battery 14a and the second battery 14b are attached to the fixture body 11 by the case 102, a gap is provided between the bottom surface 19 of the fixture body 11 and the mounting portion 108 of the case 102. Also, the side plate portion 107 on the protruding portion 101 side does not cover the entire first battery 14a and the second battery 14b. Therefore, the first battery 14a and the second battery 14b can dissipate heat from the portion not covered by the side plate portion 107 through the gap between the bottom surface 19 and the mounting portion 108 into the space between the fixture body 11 and the first light source unit 12.

[0080] Furthermore, when the battery 14 is attached to the fixture body 11 by the case 102, the length X from one end to the other of the protruding portion 101 is longer than the length Y from the surface facing the bottom portion 19 of the battery 14 to the surface facing the first surface 140 of the mounting portion 106. Therefore, a gap 129 is provided between the battery 14 and the bottom portion 19. In other words, the bottom portion 19 of the fixture body 11 and the battery 14 do not come into contact. By providing a gap 129 between the bottom portion 19 and the battery 14, the heat from the battery 14 can be dissipated into the space between the fixture body 11 and the first light source unit 12, and the external load on the battery 14 can be reduced because the battery 14 is not compressed by the bottom portion 19 and the case 102.

[0081] Furthermore, the length Z from the end of the side plate portion 107 on the mounting portion 106 side to the flange portion 112 is longer than the length Y from the surface facing the bottom portion 19 of the battery 14 to the surface facing the first surface 140 of the mounting portion 106. Therefore, the battery 14 can be inserted into the notch portion 24 using the flange 112 without contacting the bottom portion 19 of the device body 11.

[0082] Furthermore, since the wiring section 131 is held in place by the fixture-side wiring retaining section 124 and the wiring retaining section 120 between the fixture body 11 and the case 102, the wiring section 131 only needs to have the minimum length required to reach the wiring retaining section 120 provided on the case 102, thereby reducing the manufacturing cost of the wiring section 131.

[0083] Furthermore, although the above-described embodiment describes a configuration in which two batteries, the first battery 14a and the second battery 14b, are placed on the first surface 140 of the mounting section 106, the invention is not limited to this configuration, and for example, a configuration in which only one battery is placed on the first surface 140 of the mounting section 106 may also be used. When only one battery is placed on the first surface 140 of the mounting section 106, the wiring holding section 120 is attached to one of the ends in the longitudinal direction of the case 102, in the gap between the curved surface 36 of the battery and the case 102, to prevent the wiring holding section 120 from interfering with the battery.

[0084] In the embodiment described above, the wiring retaining portion 120 is attached to the case 102. However, the invention is not limited to this configuration; for example, the wiring retaining portion 120 may be formed by cutting and bending a part of the case 102.

[0085] Furthermore, although the above-described embodiment described a configuration in which the wiring holding portion 120 is attached to the center of the mounting portion 106, it is not limited to this configuration; for example, it may be attached to the short end of the mounting portion 106, or to the side of the case 102, etc.

[0086] Furthermore, although the above-described embodiment shows an embodiment in which there is an air gap 123 between the device body 11 and the first battery 14a and the second battery 14b, the embodiment is not limited to this, and for example, a heat dissipation sheet may be provided between the device body 11 and the first battery 14a and the second battery 14b, and the heat from the first battery 14a and the second battery 14b may be dissipated to the device body 11 via the heat dissipation sheet.

[0087] Furthermore, although the above-described embodiment shows a configuration in which the case 102 is attached by attaching the fixing member 110 to the screw hole 201 of the protrusion 101, the configuration is not limited to this as long as the case 102 is attached to the other end of the protrusion 101. For example, a screw thread may be provided on the other end of the protrusion 101, the screw thread of the protrusion 101 may be inserted through the mounting hole 109 of the case 102, and the fixing member 110, which has a screw hole, may be attached to the screw thread that has been inserted through the mounting hole 109. Alternatively, the other end of the protrusion 101 and the fixing member 110 may have magnets and be fixed by magnetic force, or the mounting portion 108 of the case 102 may have a magnet and be attached by magnetic force, etc.

[0088] Furthermore, since the wiring holding section 120 is positioned in the center of the back side of the mounting section 106 of the case 102, the length of the wiring from the first battery 14a and the second battery 14b mounted on the mounting section 106 to the connection section 132 held by the wiring holding section 120 becomes uniform. Therefore, there is no need to leave extra length in the wiring of the first battery 14a and the second battery 14b, and the first battery 14a and the second battery 14b can be connected to the connection section 132 with the minimum length of wiring to the connection section 132, making the connection work easier. In addition, it prevents the wiring extending from the first battery 14a and the second battery 14b from being pinched between the fixture body 11 and the first light source unit 12.

[0089] Furthermore, when the first battery 14a and the second battery 14b, each having a curved surface 36, are placed on the mounting portion 106 of the case 102, and the wiring holding portion 120 is positioned in the center of the second surface 141 of the mounting portion 106 of the case 102, the first return portion 126 of the wiring holding portion 120, which is provided on the first surface 140 side of the mounting portion 106 of the case 102, is located between it and the gap 123 provided by the curved surfaces 36 of the first battery 14a and the second battery 14b. Therefore, the wiring holding portion 120 does not interfere with the first battery 14a and the second battery 14b, and does not affect the process of placing the first battery 14a and the second battery 14b on the mounting portion 106.

[0090] Furthermore, the mounting hole 109 may be formed as an elongated hole. If the mounting hole 109 is an elongated hole, even if there is a misalignment between the mounting hole 109 and the screw hole 201 of the protrusion 101, the mounting position of the mounting hole 109 has width, so the case 102 and the protrusion 101 can be fixed with the fixing member 110.

[0091] Furthermore, when the battery 14 is placed on the first surface 140 of the mounting section 106, the length X from one end to the other of the protruding portion 101 is longer than the length Y from the surface facing the bottom surface 19 of the battery 14 to the surface facing the mounting section 106. Therefore, the work of fixing the case 102 and the protruding portion 101 with the fixing portion 110 can be performed at a position close to the opening 22 of the main body of the device 11, resulting in good workability.
