[0074] Optical Components 470 The optical member 470 is a lens that adjusts the spread of the light emitted by the light source unit 410. The optical member 470 has a light distribution characteristic that spreads light to a range required as an emergency light source. The optical member 470 has, for example, a bud wing-shaped light distribution characteristic. The optical member 470 is formed of, for example, a material that is transparent and non-flammable. The material that is transparent and non-flammable is glass or the like. The optical member 470 is disposed on the mounting unit 443. The optical member 470 has a light-transmitting portion 480 and a flange portion 490. The optical member 470 is disposed so as to face the light passing hole 220 of the cover unit 200. The lower end of the optical member 470 is disposed at a position that is above the lower surface of the cover main portion 210 and below the upper end of the cover inclined portion 221.

[0075] Translucent part 480 The light transmitting section 480 is a section through which the light emitted by the light source section 410 passes and adjusts the spread of the light. The light transmitting section 480 is the center section of the optical member 470. In a plan view, the light transmitting section 480 has a shape in which the length from the center in the direction shifted by 45 degrees from the longitudinal direction X is longer than the length from the center in the longitudinal direction X and the length from the center in the lateral direction Y. By making the light transmitting section 480 have such a shape, even if the floor surface of the irradiated area is rectangular, the light can easily reach the corners of the irradiated area.

[0076] Flange 490 The flange portion 490 is provided on the outer periphery of the light transmitting portion 480. In a plan view, the flange portion 490 extends so as to protrude from the outer periphery of the light transmitting portion 480 to the outside of the light transmitting portion 480. The flange portion 490 has a flat flange portion 491 at the upper portion. When the optical member 470 is placed on the placement portion 443, the flange portion flat portion 491 is placed on the elastic portion 448 of the holder 430. When the flange portion 490 of the optical member 470 is pressed against the placement portion 443 by the first fixing portion 450 and the second fixing portion 460, the elastic portion 448 elastically deforms upward. This allows the holder 430 to hold the optical member 470 while allowing for a dimensional error in the vertical direction Z of the flange portion 490. Moreover, the elastic portion 448 elastically deforms so as to press the flange portion 490 of the optical member 470 against the first fixing portion 450 and the second fixing portion 460. Therefore, it is possible to suppress misalignment between the optical member 470 and the light source unit 410, and it is possible to supply light with a stable light distribution.

[0077] The flange portion 490 has a positioning recess 492 recessed downward on the flange portion planar portion 491. In other words, the flange portion 490 has the positioning recess 492 at a position between the outer periphery of the flange portion 490 and the light-transmitting portion 480. Then, the positioning protrusion 447 of the main mounting portion 445 of the holder 430 is inserted into the positioning recess 492 of the flange portion 490, whereby the optical member 470 is positioned in the holder 430 in the planar direction.

[0078] Here, in the conventional lighting device, the holder has a plurality of ribs that contact the outer periphery of the flange of the optical member. In the conventional lighting device, the optical member is positioned in the holder by the plurality of ribs contacting the outer periphery of the flange of the optical member. That is, in the conventional lighting device, the optical member is positioned using the outer periphery of the flange that is located at the position farthest from the light-transmitting portion. Therefore, in the conventional lighting device, the positioning accuracy of the light-transmitting portion of the optical member relative to the light source is low. On the other hand, in the lighting device 1 according to the present embodiment, the optical member 470 is positioned in the holder 430 at a position between the outer periphery of the flange 490 and the light-transmitting portion 480. That is, the optical member 470 of the lighting device 1 according to the present embodiment is positioned in the holder 430 at a position closer to the light-transmitting portion 480 than in the conventional lighting device. Therefore, in the lighting device 1 according to the present embodiment, the positioning accuracy of the light-transmitting portion 480 of the optical member 470 relative to the light source unit 410, which is the light source, is improved compared to the conventional lighting device.

[0079] Note that a positioning protrusion 447 may be provided at a position between the outer periphery of flange 490 and light-transmitting portion 480. Then, holder 430 may be provided with a positioning recess 492. In other words, flange 490 may be provided with one of positioning protrusion 447 and positioning recess 492 at a position between the outer periphery of flange 490 and light-transmitting portion 480. Then, holder 430 may be provided with the other of positioning protrusion 447 and positioning recess 492.

[0080] The shape of the outer periphery of the flange portion 490 is an arc-shaped portion 494 at a portion facing the arc-shaped portion 444a of the outer wall portion 444 of the mounting portion 443. Also, the shape of the outer periphery of the flange portion 490 is a straight portion at a portion facing the second straight portion 444b of the outer wall portion 444 of the mounting portion 443. Hereinafter, the straight portion of the outer periphery of the flange portion 490 is referred to as a first straight portion 493. That is, the outer periphery of the flange portion 490 includes an arc-shaped portion 494 and a pair of first straight portions 493 arranged opposite to each other. The distance between the pair of second straight portions 444b is longer than the distance between the pair of first straight portions 493 and shorter than the diameter of the arc-shaped portion 494. By forming the outer periphery of flange 490 in this shape, when optical member 470 is placed on mounting portion 443, if the angle of optical member 470 with respect to mounting portion 443 is incorrect, optical member 470 cannot be placed on mounting portion 443. Therefore, by forming the outer periphery of flange 490 in this shape, it is possible to prevent optical member 470 from being placed at an incorrect angle with respect to mounting portion 443, and the reliability of illumination device 1 is improved.

[0081] Heat dissipation part 500 The heat dissipation section 500 dissipates heat generated from the light source section 410 to the main body section 100, and is made of a material with high thermal conductivity. The heat dissipation section 500 is formed, for example, by bending a metal plate. The heat dissipation section 500 is formed in a U-shape with an opening on the upper side. The heat dissipation section 500 has a heat dissipation section main section 510, a heat dissipation section first side section 520, and a heat dissipation section second side section 530.

[0082] Heat dissipation main part 510 The heat dissipation main part 510 is formed in a rectangular plate shape. The heat dissipation main part 510 has a holder hole 511, which is a screw hole. The holder fastener 442 inserted into the holder mounting hole 441 is screwed into the holder hole 511, so that the holder 430 is attached to the heat dissipation main part 510. At this time, the light source board 420 and the insulating plate 540 are sandwiched between the holder 430 and the heat dissipation main part 510. The heat dissipation main part 510 has a heat dissipation main part protrusion 512 that protrudes downward at an end of the heat dissipation main part 510 in the longitudinal direction X that is on the battery passage hole 240 side. In addition, the heat dissipation main part protrusion 512 has a groove part 513 that penetrates in the longitudinal direction X at the end part in the downward direction. The groove part 513 is a groove part in which a battery cover fastener (not shown) inserted into the cover main part first wall part hole 251 is caught.

[0083] Heat dissipation section first side portion 520 The heat dissipation section first side portion 520 is provided so as to protrude upward from an end portion of the heat dissipation section main portion 510 in the short side direction Y that is on the first lighting device 3 side. The heat dissipation section first side portion 520 is formed with a heat dissipation section mounting hole 521 and a heat dissipation section hook hole 522. The heat dissipation section mounting hole 521 is a screw hole to which the heat dissipation section fixing device 134 is attached, and is for fixing the heat dissipation section 500 and the main body section 100. The heat dissipation section hook hole 522 is for inserting the main body wall section second protrusion portion 136 of the main body wall section 130.

[0084] Heat dissipation section second side 530 The heat dissipation section second side portion 530 is provided to protrude upward from an end portion of the heat dissipation section main portion 510 in the short side direction Y, the end portion being opposite the end portion of the heat dissipation section first side portion 520. The heat dissipation section second side portion 530 is formed with a guide groove 531. The heat dissipation section second side portion 530 also includes a fixing recess 532.

[0085] Guide groove 531 The guide groove 531 is a groove that has an opening at an upper end and extends downward.

[0086] Fixing recess 532 The fixing recess 532 is adapted to be engaged with a locking portion 612 of the control portion 600, which will be described later. In this embodiment, the fixing recess 532 is a hole penetrating the heat dissipation portion second side portion 530.

[0087] Insulating plate 540 The insulating plate 540 is a plate-shaped member that is disposed between the light source unit 410 and the heat dissipation unit 500 and provides insulation between the light source unit 410 and the heat dissipation unit 500 .

[0088] Control unit 600 The control unit 600 controls the lighting state of the light source unit 410. The control unit 600 also controls the charging and discharging of the battery 800. The heat dissipation unit 500 is attached to the control unit 600 as described below. In other words, the control unit 600 and the light source module 400 are fixed by attaching the heat dissipation unit 500. The control unit 600 and the light source module 400 fixed in this manner are housed in the housing 4a. The control unit 600 has a first control cover 610, a second control cover 620, and a control board unit 650. The first control cover 610 and the second control cover 620 form an outer shell of the control unit 600, and the control board unit 650 is housed in the outer shell.

[0089] Control No. 1 Cover 610 The control first cover 610 is one half of a cover forming the outer shell of the control unit 600, and is made of resin or the like. The control first cover 610 has a guide protrusion 611 and a locking portion 612 on the outer surface. The control first cover 610 also has a control first cover hole portion 613 and a control first cover fixing portion 614 on the upper and lower portions.

[0090] Guide protrusion 611 The guide protrusion 611 is a protrusion that protrudes from the outer surface of the first control cover 610, and the amount of protrusion increases from the top to the bottom. The guide protrusion 611 is movably inserted into the guide groove 531 of the heat dissipation part second side part 530 and is guided by the guide groove 531 when the heat dissipation part 500 is attached to the control part 600.

[0091] Locking portion 612 The locking portion 612 is a protrusion that protrudes from the outer surface of the first control cover 610, and the amount of protrusion increases from the bottom to the top. When the heat dissipation portion 500 is attached to the control portion 600, the locking portion 612 is hooked into the fixing recess 532 of the heat dissipation portion second side portion 530. In this way, the heat dissipation portion 500 is attached to the control portion 600, and the control portion 600 and the light source module 400 are fixed together.

[0092] Here, in the conventional lighting device, the control unit is fixed to the mounting member to which the control unit is attached with a screw. In addition, in such a conventional lighting device, the light source module is also fixed to the above-mentioned mounting member with a screw. That is, in the conventional lighting device, when mounting the control unit and the light source module, the work of fixing the control unit with a screw and the work of fixing the light source module with a screw are required. Therefore, in the conventional lighting device, the installation work of the control unit and the light source module is time-consuming. On the other hand, in the lighting device 1 according to the present embodiment, the light source module 400 and the control unit 600 can be fixed without using a screw. Therefore, in the lighting device 1 according to the present embodiment, the installation work of the control unit 600 and the light source module 400 can be performed more easily than in the past.

[0093] The fixing recess 532 may be provided in the control unit 600, and the locking portion 612 may be provided in the heat dissipation unit 500. The fixing recess 532 and the locking portion 612 provided in the light source module 400 may be provided in a component other than the heat dissipation unit 500, as long as the fixing recess 532 and the locking portion 612 are components of the light source module 400. That is, the light source module 400 may have one of the locking portion 612 and the fixing recess 532. The control unit 600 may have the other of the locking portion 612 and the fixing recess 532. The fixing recess 532 and the locking portion 612 provided in the light source module 400 is preferably provided in the heat dissipation unit 500. The heat dissipation unit 500 releases heat generated from the light source unit 410, and is a relatively large component among the components of the light source module 400. For this reason, it is relatively easy to provide the fixing recess 532 or the locking portion 612 in the heat dissipation unit 500. Therefore, by providing either the fixing recess 532 or the locking portion 612, whichever is provided in the light source module 400, in the heat dissipation portion 500, the manufacturing of the lighting device 1 becomes easier.

[0094] As described above, the heat dissipation section 500 is formed with the guide groove 531. The control section 600 is provided with the guide protrusion 611. Therefore, when the light source module 400 and the control section 600 are fixed, the guide protrusion 611 is guided by the guide groove 531, and the locking section 612 is guided to the fixing recess 532. Therefore, the lighting device 1 according to the present embodiment further facilitates the installation work of the control section 600 and the light source module 400. The guide groove 531 may be formed in a component other than the heat dissipation section 500 as long as the component is a component of the light source module 400. The guide groove 531 may be formed in the control section 600, and the guide protrusion 611 may be provided in the light source module 400. That is, it is sufficient that one of the light source module 400 and the control section 600 has the guide protrusion 611. The guide groove 531 for guiding the locking portion 612 to the fixing recess 532 may be formed on the other of the light source module 400 and the control portion 600 .

[0096] Guide protrusion 621 and locking portion 622 The guide protrusion 621 is formed in the same manner as the guide protrusion 611. The locking portion 622 is formed in the same manner as the locking portion 612. In this embodiment, the guide protrusion 621 and the locking portion 622 are not used to fix the control portion 600 and the light source module 400 together. However, if it is desired to reverse the mounting direction of the light source module 400 relative to the control portion 600, this can be achieved by providing the guide protrusion 621 and the locking portion 622.

[0097] Wire connection port The electric wire connection port is formed in a concave shape from the outer surface side toward the inner surface side of the control second cover 620, and the connection port is formed at the bottom of the concave shape. The opening of the connection port is an inclined portion in which the opening becomes smaller from the outer surface side toward the inner surface side of the control second cover 620. This makes it easier to insert the electric wire connector into the electric wire connection port. In addition, when inserting the electric wire connector into the electric wire connection port, a space for the operator's fingers to enter can be secured. In this embodiment, the control second cover 620 has an external power supply connection port 623, a battery connection port 624, and a light source connection port 625 as electric wire connection ports.

[0098] The external power supply connection port 623 is a wire connection port into which a connector of the wire 50 connected to an external power supply is inserted. By inserting the connector of the wire 50 into the external power supply connection port 623, the connector is connected to a connector mounted on the control board unit 650. The battery connection port 624 is a wire connection port into which a connector provided at one end of a wire connected to a battery 800 is inserted. By inserting a connector provided at one end of a wire connected to a battery 800 into the battery connection port 624, the connector is connected to a connector mounted on the control board unit 650. Note that in FIG. 11 and the like, the connector provided at the other end of the wire connected to the battery 800 is illustrated as the second connector 61. The light source connection port 625 is a wire connection port into which a connector of the wire 70 connected to the light source unit 410 is inserted. By inserting the connector of the electric wire 70 into the light source connection port 625 , the connector is connected to a connector mounted on the control board unit 650 .

[0099] Wire holding part The electric wire holding portion is provided to hold, on the control second cover 620, electric wires that connect to a connector mounted on the control board portion 650. In the present embodiment, the control second cover 620 has, as electric wire holding portions, a battery electric wire holding portion 626 that holds electric wires connected to the battery 800, and a light source electric wire holding portion 627 that holds electric wires 70 connected to the light source portion 410.

[0100] Battery wire holding part 626 The battery electric wire holding portion 626 has a pair of protruding pieces protruding from the outer surface of the control second cover 620. The pair of protruding pieces face each other in the up-down direction. Furthermore, the tip portions of the protruding pieces are provided with hook portions formed so as to approach each other. By inserting an electric wire connected to the battery 800 between the pair of protruding pieces, the electric wire is held by the battery electric wire holding portion 626. Furthermore, the tip portion of the battery electric wire holding portion 626 abuts against the heat dissipation portion first side portion 520 in a state in which the heat dissipation portion 500 is attached to the control portion 600. This makes it possible to prevent the electric wire connected to the battery 800 from coming off the battery electric wire holding portion 626.

[0101] Light source wire holding part 627 The light source electric wire holding portion 627 has a protruding piece protruding from the outer surface of the control second cover 620 and a hook portion protruding downward from the tip of the protruding piece. By inserting the electric wire 70 connected to the light source unit 410 between the hook portion and the control second cover 620, the electric wire 70 is held by the light source electric wire holding portion 627.

[0102] Rib 628 The rib 628 is provided so as to protrude from the outer surface of the second control cover 620. The tip of the rib 628 abuts against the heat dissipation portion first side portion 520 when the heat dissipation portion 500 is attached to the control portion 600.

[0103] Monitor unit 640 The monitor unit 640 is provided in a flat plate shape at the bottom of the second control cover 620. The monitor unit 640 is exposed to the outside from the cover insertion hole 230. The monitor unit 640 has a light passing hole 641, a switch hole 642, and a light receiving hole 643 formed therein. The light passing hole 641 is a hole through which light emitted by a monitor LED provided on the control board unit 650 passes. The switch hole 642 is a hole into which a pressing part of a switch 651 provided on the control board unit 650 is inserted. The light receiving hole 643 is a hole through which the light receiving unit 652 provided on the control board unit 650 is exposed to the outside.

[0104] Control board section 650 The control board section 650 has a charging circuit (not shown) that stores power supplied from an external power source in the battery 800. The control board section 650 also has a lighting circuit (not shown) that supplies power from the battery 800 to the light source section 410 and lights up the light source section 410 when the supply of power from the external power source is stopped. The control board section 650 also has a switch 651, a light receiving section 652, and a monitor LED (not shown) as described above. The switch 651 starts checking the state of the battery 800. When the switch 651 is pressed, power is supplied from the battery 800 to the light source section 410, and the switch 651 is turned on. The light receiving section 652 receives a signal to start checking from an external terminal such as a remote control. When the light receiving section 652 receives the signal to start checking, checking the state of the battery 800 starts. The monitor LED emits light according to the inspection state and the inspection result of the battery 800, and notifies the operator of the inspection state.

[0105] Battery holding part 700 The battery holding portion 700 is attached to the main body bottom portion 110 of the main body portion 100, and holds a battery 800. The battery holding portion 700 is provided at a position facing the battery passing hole 240 of the cover portion 200 in the vertical direction Z. The battery holding portion 700 has a battery holding portion bottom portion 710, a battery holding portion side portion 720, and a harness fixing portion 730. The battery holding portion 700 is formed, for example, by bending a metal plate.

[0106] Battery holding part bottom 710 Battery holding section bottom 710 is formed in a plate shape. Battery holding section bottom 710 is formed with holes 711 into which screws are inserted for fixing to main body bottom 110 of main body 100. Battery holding section bottom 710 also has hooks 712 that hook into holes (not shown) formed in main body bottom 110.

[0107] Battery holder side 720 The battery holding section side 720 is provided so as to protrude downward from an end portion of the battery holding section side 720 opposite to the end portion of the battery holding section side 720 on the main body wall section 130 side when the battery holding section 700 is attached to the main body section 100. The battery holding section side 720 has a support section 721, a battery support section 723, and a battery guide section 724.

[0108] Support part 721 The support portion 721 is formed, for example, by making a slit penetrating the battery holding portion side portion 720 in a U-shape that is convex downward. The support portion 721 is processed so as to be elastically deformable in the direction in which the battery holding portion side portion 720 and the main body wall portion 130 face each other when the battery holding portion 700 is attached to the main body portion 100. The support portion 721 has a clamping protrusion 722 that protrudes in the direction toward the main body wall portion 130 when the battery holding portion 700 is attached to the main body portion 100. The clamping protrusion 722 is provided at a position facing the clamping protrusion 137 of the main body wall portion 130 in the short-side direction Y. It is not necessary for the clamping protrusion 722 and the clamping protrusion 137 of the main body wall portion 130 to be strictly opposed to each other in the short-side direction Y. The clamping protrusion 722 and the clamping protrusion 137 of the main body wall 130 may face each other at a slight incline from the short-side direction Y. When the battery 800 is held inside the housing 4a, the clamping protrusion 722 clamps the battery 800 together with the clamping protrusion 137. That is, the lighting device 1 according to the first embodiment is provided with a pair of clamping protrusions that clamp the battery 800. The lighting device 1 is also provided with the clamping protrusion 722, which is one of the pair of clamping protrusions, and is provided with a support part 721 that is elastically deformable in the opposing direction of the pair of clamping protrusions.

[0109] Battery support part 723 The battery support section 723 is formed, for example, by making a slit penetrating the battery holding section side section 720 into an upwardly convex U-shape. The battery support section 723 is formed so as to be freely bendable with the lower end section as a fulcrum. The number of tube batteries 811 (described later) in the battery 800 varies depending on the battery capacity. Furthermore, the length of the battery 800 in the vertical direction Z varies as the number of tube batteries 811 varies. More specifically, the length of the battery 800 in the vertical direction Z of a battery main body section 810 (described later) of the battery 800 varies.

[0110] For the battery 800 whose length in the vertical direction Z changes in this way, the battery support part 723 is used as follows. For example, in the case of the battery 800 having six tube batteries 811, the length of the battery 800 in the vertical direction Z is long. For this reason, the battery support part 723 is not bent. Then, the battery 800 is housed in the housing 4a in which the battery holding part 700 having such a shape is fixed to the main body bottom part 110. Also, the length of the battery 800 in the vertical direction Z of the battery 800 with four tube batteries 811 is shorter than that of the battery 800 with six tube batteries 811. For this reason, the battery support part 723, which is provided so as to be freely bendable, is bent. When the battery support part 723 is bent, the battery 800 held by the clamping protrusions 722 and the clamping protrusions 137 comes into contact with the battery support part 723. By using the battery support portion 723 in this manner, even if the length of the battery 800 in the up-down direction Z changes, the clamping protrusion 722 and the clamping protrusion 137 can clamp the battery 800 at a desired position.

[0111] Battery guide 724 The battery guide portion 724 is a plate-like member attached to the battery holding portion side portion 720 and is elastically deformable in a direction intersecting with the surface of the battery holding portion side portion 720. The battery guide portion 724 is provided so as to cover one of the ends of the battery 800 on the longitudinal direction X side. The battery guide portion 724 guides the battery 800 when the battery 800 is inserted into the housing 4a. The battery guide portion 724 also serves as a stopper that prevents the battery 800 held in the housing 4a from easily falling out of the battery holding portion 700.

[0112] Harness fixing part 730 The harness fixing portion 730 is aligned with the battery holding portion bottom portion 710 in the longitudinal direction X. The harness fixing portion 730 is disposed below the battery holding portion bottom portion 710. The harness fixing portion 730 is formed in a plate shape. The harness fixing portion 730 is formed with a harness fixing hole 731 penetrating in the vertical direction. The harness fixing hole 731 is provided with a second connector 61 of an electric wire connected to the battery 800. In other words, the harness fixing hole 731 is provided with a second connector 61 of an electric wire connecting the control portion 600 and the battery 800. That is, it can be said that the housing 4a is provided with the second connector 61 inside the housing 4a. The second connector 61 is provided at a position facing the battery passing hole 240 of the cover portion 200 in the vertical direction Z.

[0113] A first connector 831 of the battery 800, which will be described later, is connected to the second connector 61. Here, the second connector 61 is provided along the vertical direction Z. Therefore, the connection direction between the first connector 831 and the second connector 61 is the vertical direction Z. In other words, the connection direction between the first connector 831 and the second connector 61 is the opposing direction between the battery 800 accommodated in the housing 4a and the battery passing hole 240. In addition, in this embodiment, a gap large enough for an operator's thumb to fit in is provided between the harness fixing hole 731 and the cover first wall portion 270 of the cover portion 200 so that an operator's finger can reach the second connector 61 when connecting the second connector 61 and the first connector 831. The gap large enough for an operator's thumb to fit in is, for example, a gap of about 20 mm.

[0114] battery 800 The battery 800 is a secondary battery such as a storage battery. The battery 800 is, for example, a nickel-metal hydride battery, a nickel-cadmium battery, or an alkaline ion battery. The battery 800 includes a battery main body 810 and a harness 830.

[0115] Battery body 810 The battery main body 810 includes a plurality of tube batteries 811. The plurality of tube batteries 811 are connected to form the battery main body 810. The number of tube batteries 811 varies depending on the capacity of the battery 800. For example, when the battery main body 810 includes four tube batteries 811, the tube batteries 811 are arranged in two vertical rows and two horizontal rows. Also, when the battery main body 810 includes six tube batteries 811, the tube batteries 811 are arranged in three vertical rows and two horizontal rows. The outer periphery of the plurality of tube batteries 811 is covered with a film 820. That is, the battery 800 includes a film 820 that covers the outer periphery.

[0116] Harness 830 The harness 830 is connected to the battery main body 810, and has the above-mentioned first connector 831 at its tip. The control unit 600 and the battery 800 are connected by connecting the first connector 831 and the second connector 61. This allows power supplied from an external power source to be stored in the battery 800. In addition, power can be supplied from the battery 800 to the light source unit 410 to light the light source unit 410.

[0117] Here, the battery of the conventional lighting device is held in the lighting fixture as follows: The conventional lighting fixture has a housing that houses the battery. This housing is provided with a holding part whose upper end is fixed to the housing and which is elastically deformable. This holding part supports the lower corners of the battery and presses the battery against the side of the housing to hold the battery within the housing. In other words, the conventional lighting device holds the battery by the elastic force generated when the holding part elastically deforms. For this reason, in the conventional lighting device, if the elastic force of the holding part decreases, the battery holding force decreases.

[0118] On the other hand, in the lighting device 1 according to the present embodiment, when the battery 800 is held in the housing 4a, the battery 800 is held between the clamping protrusion 722 and the clamping protrusion 137. At this time, the clamping protrusion 722 and the clamping protrusion 137 clamp the position indicated by the outlined arrow in FIG. 29. Specifically, the clamping protrusion 722 and the clamping protrusion 137 clamp the position between the tube battery 811. As a result, when the battery 800 is held between the clamping protrusion 722 and the clamping protrusion 137, the film 820 of the battery 800 is bent. That is, the second lighting device 4 of the lighting device 1 according to the present embodiment is configured such that the clamping protrusion 722 and the clamping protrusion 137 bend the film 820 to hold the battery 800, and the battery 800 is held in the housing 4a. Therefore, when the lighting device 1 according to the present embodiment holds the battery 800, the elastic deformation of the support portion 721 provided with the clamping protrusion 722 can be suppressed compared to the elastic deformation of the holding portion of the conventional lighting device. Therefore, the lighting device 1 according to the present embodiment can suppress a decrease in the elastic force of the support portion 721. Furthermore, in the lighting device 1 according to the present embodiment, even if the elastic force of the support portion 721 is reduced, the clamping protrusion 722 and the clamping protrusion 137 can be caught by the film 820 and the battery 800 can be held. Therefore, the lighting device 1 according to the present embodiment can suppress a decrease in the holding force of the battery 800 more than in the past.

[0119] Method of housing the battery 800 in the housing 4a Next, a method of housing the battery 800 in the housing 4a will be described with reference to FIGS.

[0120] 30 to 32 are diagrams for explaining a method of housing a battery in the housing of the second lighting device according to the embodiment, and are perspective views of the second lighting device observed from below. Note that FIG. 30 shows a state before the battery 800 is housed in the housing 4a. FIG. 31 shows a state in the middle of housing the battery 800 in the housing 4a. FIG. 32 shows a state after the battery 800 has been housed in the housing 4a.

[0121] First, the battery cover 290 is rotated to open the battery passage hole 240. Then, the battery 800 is held so that the harness 830 faces downward, and the battery 800 is inserted into the housing 4a through the battery passage hole 240. Then, the battery body 810 of the battery 800 is clamped in the short-side direction Y by the clamping protrusion 722 and the clamping protrusion 137. This allows the battery body 810 to be held in the housing 4a. At this time, in the long-side direction X, the battery body 810 is supported by the body side portion 140 of the main body portion 100 and the battery guide portion 724 of the battery holding portion 700. Then, the first connector 831 of the harness 830 of the battery 800 is connected to the second connector 61. This step of connecting the first connector 831 of the harness 830 to the second connector 61 may be performed before the step of holding the battery body 810 in the housing 4a. The method of removing the battery 800 from the housing 4a is the reverse of the method of housing the battery 800 in the housing 4a.

[0122] Here, in the conventional lighting device, the connection direction between the first connector of the battery and the second connector in the housing is perpendicular to the opposing direction between the battery and the battery passage hole. In other words, in the conventional lighting device, the first connector and the second connector need to be connected in the opposing direction between the battery body and the second connector. Therefore, when connecting the first connector and the second connector, it is difficult for the worker to visually recognize the second connector, and it is difficult to connect the first connector and the second connector. In addition, in the conventional lighting device, since the first connector and the second connector need to be connected in the opposing direction between the battery body and the second connector, the space for performing the connection work between the first connector and the second connector is narrow. Thus, in the conventional lighting device, it is difficult to accommodate the battery in the housing and remove the battery from the housing.

[0123] On the other hand, in the lighting device 1 according to the present embodiment, the connection direction between the first connector 831 of the battery 800 and the second connector 61 in the housing 4a is the opposing direction between the battery 800 and the battery passing hole 240. Therefore, in the lighting device 1 according to the present embodiment, when connecting the first connector 831 and the second connector 61, the worker can easily visually confirm the second connector 61. In addition, in the lighting device 1 according to the present embodiment, since the first connector 831 and the second connector 61 are connected in the opposing direction between the battery 800 and the battery passing hole 240, it is easy to secure a space for performing the connection work between the first connector 831 and the second connector 61. In addition, since a sufficient space is secured around the second connector 61 for the worker's fingers to enter, even if the second connector 61 cannot be visually confirmed, the first connector 831 and the second connector 61 can be easily connected by the sense of the fingers. Therefore, in the lighting device 1 according to the present embodiment, it is easier to accommodate the battery 800 in the housing 4a and remove the battery 800 from the housing 4a than in the conventional lighting device.

[0124] In addition, in this embodiment, the second connector 61 is disposed at a position that does not overlap the battery body 810 of the battery 800 housed in the housing 4a in the longitudinal direction X. In other words, in this embodiment, the second connector 61 is disposed at a position that does not overlap the battery body 810 of the battery 800 housed in the housing 4a in a direction perpendicular to the opposing direction of the battery 800 housed in the housing 4a and the battery passing hole 240. When the battery body 810 and the second connector 61 overlap in the longitudinal direction X, it is necessary to perform a step of holding the battery body 810 in the housing 4a after the step of connecting the first connector 831 and the second connector 61 of the harness 830. On the other hand, by disposing the second connector 61 as in this embodiment, either the step of connecting the first connector 831 and the second connector 61 of the harness 830 or the step of holding the battery body 810 in the housing 4a may be performed first. Therefore, by arranging the second connector 61 as in this embodiment, it becomes even easier to accommodate the battery 800 in the housing 4a and to remove the battery 800 from the housing 4a.

[0125] [Variations] The lighting fixture 2 of the lighting device 1 described above was a V-shaped lighting fixture. The lighting fixture 2 may have various shapes, such as a shaded type, a one-side reflective shaded type, and a trough type. Here, when the second lighting fixture 4 of the same shape is provided on a plurality of lighting fixtures 2 of different shapes, depending on the shape of the lighting fixture 2, the light of the second lighting fixture 4 may be reflected by the lighting fixture 2, and the lighting device 1 may not be able to emit light at a specified light distribution angle. As one method for solving this problem, it is considered to make the shape of the second lighting fixture 4 different for each shape of the lighting fixture 2. However, such a method increases the lineup of the second lighting fixture 4. Therefore, in order to suppress an increase in the lineup of the second lighting fixture 4 and enable the lighting device 1 to emit light at a specified light distribution angle, the lighting device 1 may be provided with an adapter 900 as follows.

[0126] FIG. 33 is a perspective view of the lighting device according to the modified example observed from below. FIG. 34 is a plan view of the lighting device according to the modified example. FIG. 35 is a perspective view of the lighting device according to the modified example observed from above. FIG. 36 is a view of the second lighting device and the adapter of the lighting device according to the modified example observed from below, showing a state in which the second lighting device and the adapter are not connected. FIG. 37 is a view of the second lighting device and the adapter of the lighting device according to the modified example observed from below, showing a state in which the second lighting device and the adapter are connected. FIG. 38 is a view of the second lighting device and the adapter of the lighting device according to the modified example observed from the side. FIG. 39 is a side view showing the second lighting device according to the comparative example. Note that the second lighting device 4 shown in FIG. 39 shows the second lighting device 4 fixed to the bottom wall part 12 of the main body part 11 which is the base part without connecting the adapter 900.

[0127] The fixture inclination portion 15 of the lighting fixture 2 of the lighting device 1 according to the modification is inclined downward as it is away from the main body 11. In the lighting device 1 including such a lighting fixture 2, if the second lighting fixture 4 is directly fixed to the bottom wall 12 of the main body 11, which is the base portion, there is a concern that a part of the light emitted from the light source unit 410 may hit the fixture inclination portion 15. In this regard, in order to prevent the light emitted from the light source unit 410 from hitting the fixture inclination portion 15, the lighting device 1 according to the modification includes an adapter 900. When the second lighting fixture 4 is fixed to the bottom wall 12 of the main body 11 via the adapter 900, the connector 120 is bent downward from the end of the short side direction Y of the main body bottom 110 and arranged along the main body wall 130.

[0128] Adapter 900 The adapter 900 is connected to the second lighting device 4 and the bottom wall 12 of the main body 11 which is the base, and fixes the second lighting device 4 to the bottom wall 12 of the main body 11 which is the base. The adapter 900 has an adapter main part 910 and an adapter side part 920. The adapter 900 is formed, for example, by bending a metal plate.

[0129] Adapter main part 910 The adapter main part 910 is formed in a plate shape. The adapter main part 910 has an adapter first hole 911, an adapter second hole 912, and an adapter third hole 913. The adapter first hole 911 is a hole into which the main body wall hook part 138 formed in the main body wall part 130 is hooked. The adapter second hole 912 is a hole into which the heat dissipation part fixing tool 134 for attaching the adapter 900 to the main body wall part 130 is inserted. That is, the adapter 900 and the second lighting device 4 are connected by the heat dissipation part fixing tool 134. The heat dissipation part fixing tool 134 is inserted into the adapter second hole 912 to fasten the adapter 900, the main body wall part 130, and the heat dissipation part 500 together. The adapter third hole 913 is a hole through which the electric wire 50 extending from the second lighting device 4 to the lighting device receiving part 18 of the lighting device 2 passes.

[0130] Adapter side 920 The adapter side part 920 is a plate-like part provided so as to protrude from the upper end of the adapter main part 910 in a direction intersecting with the adapter main part 910. The adapter side part 920 is provided with an adapter mounting hole 921. The adapter 900 is attached to the bottom wall part 12 of the main body part 11, which is the base part, by a fastener 922 such as a screw inserted into the adapter mounting hole 921. That is, the adapter 900 and the bottom wall part 12 of the main body part 11, which is the base part, are connected by the fastener 922. Here, as can be seen from a comparison between FIG. 38 and FIG. 39, when the adapter 900 is attached to the main body wall part 130, the upper end of the adapter main part 910 protrudes upward from the main body bottom part 110 of the second lighting device 4. Therefore, when the second lighting device 4 is attached to the bottom wall part 12 of the main body part 11, which is the base part, via the adapter 900, it is attached to the bottom wall part 12 of the main body part 11 in a state where it has moved downward compared to a state where the adapter 900 is not interposed. In other words, when the second lighting device 4 is attached to the bottom wall portion 12 of the main body portion 11, which is the base portion, via the adapter 900, a gap is formed between the second lighting device 4 and the bottom wall portion 12 of the main body portion 11, which is the base portion.

[0131] In this manner, the adapter 900 of the lighting device 1 according to the modified example is connected to the second lighting fixture 4 and the bottom wall 12 of the main body 11 which is the base, and fixes the second lighting fixture 4 to the bottom wall 12 of the main body 11 which is the base with a gap between the second lighting fixture 4 and the bottom wall 12 of the main body 11 which is the base. Therefore, the lighting device 1 according to the modified example can change the distance between the second lighting fixture 4 and the main body 11 which is the base by the adapter 900. Therefore, the lighting device 1 according to the modified example can use a common second lighting fixture 4 for lighting fixtures 2 of a plurality of shapes which could not use a common second lighting fixture 4 in the past. Therefore, the lighting device 1 according to the modified example can emit light from the lighting device at a specified light distribution angle while suppressing an increase in the lineup of the second lighting fixtures 4.

[0132] As described above, the lighting device 1 according to the present embodiment is a lighting device including the second lighting device 4 that emits light with power supplied from the battery 800.
