[0027] The pair of third wall portions 23 are attached to both ends in the left-right direction of the bottom portion 20, the pair of first wall portions 21, and the pair of second wall portions 22.

[0028] The tool body 2 has a recess 24 that is open toward the front. The recess 24 is formed by a bottom portion 20 and a pair of first walls 21.

[0029] The recess 24 accommodates the light source unit 3, the functional unit 4, the battery 6 and the emergency power supply unit 7.

[0030] The fixture body 2 is surrounded by a pair of first wall portions 21 and a pair of second wall portions 22, and further has a space 25 that is open toward the back side (rear) of the fixture body 2. The power supply line 8 is accommodated in the space 25. The power supply line 8 is an electric wire for supplying power from a power source (for example, a commercial AC power source).

[0031] The bottom portion 20 is a long rectangular flat plate extending in the left-right direction. Each of the pair of first walls 21 is a long rectangular flat plate extending in the left-right direction. The pair of second walls 22 are formed by bending a long rectangular flat plate extending in the left-right direction.

[0032] The bottom 20, the pair of first wall portions 21, and the pair of second wall portions 22 have the same length in the left-right direction. The bottom 20, the pair of first wall portions 21, and the pair of second wall portions 22 are integrally formed, for example, by bending a single metal plate. In this embodiment, the pair of third wall portions 23 are formed by bending a metal plate different from the bottom 20, the pair of first wall portions 21, and the pair of second wall portions 22.

[0033] As shown in FIG. 2, the bottom portion 20 has a plurality of (eg, four) long fixing holes 26 and a number of (eg, two) round introduction holes 27.

[0034] An anchor bolt (not shown) embedded in a wall surface 100 made of a concrete wall or the like can be inserted into each of the multiple fixing holes 26. The device main body 2 is fixed to the wall surface 100 by tightening a nut onto the anchor bolt inserted into the fixing hole 26.

[0035] A power supply line 8 for supplying power from a power source to the light source unit 3 can be inserted into each of the multiple introduction holes 27.

[0036] A plurality of terminal blocks 10 (three in the illustrated example) are attached near the introduction hole 27 on the front surface of the bottom 20. The plurality of terminal blocks 10 are electrically connected to the power supply line 8, a signal line for receiving a fire signal from an automatic fire alarm system installed in the building, and the like.

[0037] A plurality of (for example, two) insertion holes 210 through which the power supply lines 8 can be inserted are provided in the central portion in the left-right direction of each of the pair of first wall portions 21. The power supply lines 8 are introduced into the accommodating recess 24 through the introduction hole 27 of the bottom portion 20 or the insertion hole 210 of the first wall portion 21.

[0040] A battery attachment section 28 to which a battery 6 is detachably attached is provided at one end (e.g., the left end) of the bottom 20 in the left-right direction. The battery attachment section 28 is disposed at a position on the bottom 20 that is covered by both the light source unit 3 and the functional unit 4.

[0041] The battery attachment portion 28 has a pair of elastically deformable clamping pieces 280. The battery 6 is clamped between the pair of clamping pieces 280, thereby allowing the battery 6 to be detachably attached to the bottom portion 20. The battery 6 is, for example, a rechargeable secondary battery such as a nickel-metal hydride battery.

[0042] An emergency power supply unit 7 is fixed to the other end (e.g., the right end) in the longitudinal direction of the bottom 20. The emergency power supply unit 7 has a charging circuit that charges the battery 6 with power supplied from a power supply line 8, and a lighting circuit that supplies power from the battery 6 to the emergency light source unit 4a when the power supply from the power supply line 8 is stopped.

[0043] (2.2) Light source unit 1 and 2 is configured to be turned on by power from a power supply line 8. In this embodiment, the light source unit 3 has an elongated shape extending in the left-right direction. The light source unit 3 is housed in a recess 24.

[0044] The light source unit 3 has a light source section 31, a support member 30 that supports the light source section 31, a cover 32 attached to the support member 30 so as to cover the light source section 31, and a control unit 33 that controls the lighting of the light source section 31.

[0045] The light source unit 31 has a substrate 310 extending in the left-right direction, and a plurality of light-emitting elements 311 mounted in a row on the substrate 310. In this embodiment, each of the plurality of light-emitting elements 311 is, for example, an LED (light-emitting diode). That is, in this embodiment, the light source unit 31 is an LED module. Note that the light-emitting elements 311 are not limited to LEDs.

[0046] The control unit 33 controls the light emission of the light source unit 31 according to the detection result of the human detection unit 5 described later. More specifically, the control unit 33 controls the power supplied to the light source unit 31 from the power source via the power supply line 8. The control unit 33 is attached to the rear surface of the support member 30 as shown in FIG.

[0047] The support member 30 is made of a metal such as steel. The support member 30 is formed, for example, by bending a single steel plate. As shown in Figs. 3 and 4, the support member 30 has a plate-shaped main body 300 extending in the left-right direction, and a hook portion 302 connected to one end of the main body 300 in the width direction. In this embodiment, the support member 30 is disposed such that the width direction of the main body 300 is aligned with the up-down direction and the thickness direction is aligned with the front-rear direction. The hook portion 302 is connected, for example, to a lower end D1 of the main body 300.

[0048] 4, the main body 300 has a first surface S1 and a second surface S2 that face each other in the thickness direction (front-rear direction). Here, the first surface S1 is the front surface of the main body 300, and the second surface S2 is the rear surface of the main body 300.

[0049] The main body 300 supports the light source unit 31 on the first surface S1.

[0050] As shown in FIGS. 3 to 5, the hook portion 302 has a flat portion 3021 and a curved portion 3022.

[0051] The flat surface portion 3021 is a plate-like member protruding rearward from the lower end D1 of the main body portion 300. More specifically, the flat surface portion 3021 protrudes rearward from the lower end D1 so as to be perpendicular to the up-down direction. Note that "perpendicular" in this disclosure may include not only completely perpendicular, but also a state inclined within a predetermined error range (e.g., about a few degrees) with respect to the vertical direction.

[0052] The flat portion 3021 has a first end E1 connected to the lower end D1 of the main body 300, and a second end E2 different from the first end E1. That is, the first end E1 is the front end of the flat portion 3021, and the second end E2 is the rear end of the flat portion 3021.

[0053] 5, a plurality of insertion holes H1 into which fasteners 13 such as screws are inserted are provided in the flat surface portion 3021. The plurality of insertion holes H1 are aligned at equal intervals in the left-right direction.

[0054] The curved portion 3022 has a third end E3 connected to the second end E2 of the flat portion 3021, and a fourth end E4 different from the third end E3.

[0055] 4 and 5, the curved portion 3022 is a plate-like member that is curved when viewed from the left-right direction. More specifically, when viewed from the left-right direction, the curved portion 3022 starts to curve upward from the third end E3 and curves counterclockwise toward the fourth end E4. This causes the curved portion 3022 to face the second surface S2 of the main body portion 300 in the front-rear direction. In this embodiment, the position of the fourth end E4 in the up-down direction is above the center position of the curved portion 3022 in the up-down direction.

[0056] The curved portion 3022 has a constant curvature when viewed from the left and right direction, that is, the shape of the curved portion 3022 when viewed from the left and right direction is an arc shape.

[0057] A fourth end E4 of the curved portion 3022 is separated from the flat portion 3021 and the second surface S2 of the main body portion 300. This provides a gap (shortest distance Dmin, described later) between the curved portion 3022 and the second surface S2 of the main body portion 300 in the front-rear direction.

[0058] 5, the shortest distance Dmin between the curved portion 3022 and the second surface S2 in the front-rear direction is shorter than half the distance Ds1 between the second surface S2 and the second end E2 of the flat portion 3021 in the front-rear direction. In this embodiment, the shortest distance Dmin is the distance between the fourth end E4 of the curved portion 3022 and the second surface S2 in the front-rear direction.

[0059] As shown in FIGS. 3 and 4, the support member 30 further has a member-side fixing portion 301 that protrudes rearward from the second surface S2 at an upper end U1 opposite to the lower end D1 of the main body portion 300.

[0060] The member-side fixing part 301 is a long rectangular flat plate extending in the left-right direction. The member-side fixing part 301 also protrudes rearward when viewed from the left-right direction. Here, as shown in FIG. 4, the longest distance Dmax between the curved part 3022 and the second surface S2 in the front-rear direction is equal to the distance Ds2 between the second surface S2 and the tip (rear end) of the member-side fixing part 301 in the thickness direction of the main body part 300. In this embodiment, the longest distance Dmax is the distance between the rear end of the curved part 3022 and the second surface S2. As a result, for example, by abutting and fixing the rear end of the member-side fixing part 301 and the rear end of the curved part 3022 with a plate-like member or the like, the main body part 300 of the support member 30 can be in a state aligned with the up-down direction when viewed from the left-right direction.

[0061] The member-side fixing portion 301 is provided with a plurality of fixing holes 304 into which fasteners 11, 12 such as screws used to fix the support member 30 and the cover body 320 are fixed.

[0062] As shown in FIGS. 2 and 3, the cover 32 has a cover body 320 that covers the light source unit 31 from the front side, and a pair of cover ends 321.

[0063] The cover body 320 is formed in a semi-cylindrical shape that extends in the left-right direction and is open on both left-right ends and on the rear side (back surface). The cover body 320 is made of a synthetic resin (e.g., acrylic resin, polycarbonate resin, etc.) having translucency.

[0064] The cover body 320 has a flat body portion 322 extending in the left-right direction, and a pair of flat side wall portions 323 extending rearward from both ends of the body portion 322 in the width direction.

[0065] Furthermore, the cover body 320 has a pair of flat flange portions 324 that protrude inward in the vertical direction from the rear ends of the pair of side wall portions 323, and a cover side fixing portion 325 that protrudes rearward from the vertical center of the upper flange portion 324.

[0066] The cover side fixing portion 325 has a flat plate shape extending in the left-right direction so as to follow at least a part of the member side fixing portion 301 of the support member 30.

[0067] A plurality of ribs R1 (two in this embodiment) are provided on the lower surface of the cover side fixing part 325. Further, the cover side fixing part 325 is provided with a plurality of insertion holes 3251 through which the fixing devices 11, 12 are inserted.

[0068] Furthermore, the cover body 320 has a contact portion 326 that protrudes rearward from the center in the up-down direction of the lower flange portion 324 .

[0069] The contact portion 326 has a flat contact portion 3260 that protrudes rearward from the lower flange portion 324. The flat contact portion 3260 is in the form of a plate that extends in the left-right direction along the flat portion 3021 of the hook portion 302.

[0070] A plurality of ribs R2 (two in this embodiment) are provided on the upper surface of the planar contact portion 3260. Also, as shown in Fig. 5, the planar contact portion 3260 is provided with a plurality of insertion holes H2 through which the fixing device 13 is inserted. The plurality of insertion holes H2 are arranged at equal intervals in the left-right direction.

[0071] The pair of cover ends 321 are each formed in a rectangular plate shape. The pair of cover ends 321 are attached to the left and right ends of the cover main body 320 to close the openings at the left and right ends of the cover main body 320. More specifically, the cover ends 321 are attached to the left and right ends of the main body portion 322, the pair of side wall portions 323, and the pair of flange portions 324 of the cover main body 320.

[0072] In this embodiment, each of the pair of cover ends 321 is formed of a metal plate. A paint of a similar color to that of the cover body 320 is applied to the surface of the metal plate.

[0073] When the light source unit 3 is installed in the recess 24, the cover 32 is located on the front side (front side) of the recess 24 and on the front side (front side) of the pair of second walls 22 of the fixture body 2.

[0074] (2.3) Functional Unit 1 and 2 includes an emergency light source unit 4a that turns on during a power outage. More specifically, the functional unit 4 includes a pair of emergency light source units 4a positioned so as to sandwich the light source unit 3 in the left-right direction.

[0076] Each of the pair of emergency light source units 4a is turned on by power supplied from the battery 6 during a power outage of the normal power supply.

[0077] As shown in FIG. 2, each emergency light source unit 4a includes an emergency LED module 40 and a unit cover 41.

[0078] One of the pair of emergency light source units 4a (the right emergency light source unit 4a in this embodiment) is provided with an inspection unit 42 for inspecting the operation of the emergency light source unit 4a. The inspection unit 42 has, for example, two inspection switches made of push button switches, a lamp, and a light receiving element that receives a wireless signal using infrared rays as a medium.

[0079] The emergency LED module 40 includes an LED (light emitting diode) and a lens 400. The LED is, for example, a COB (chip on board) type white light emitting diode. The lens 400 is, for example, made of glass and has a substantially hemispherical shape.

[0080] The unit cover 41 is made of sheet metal. The unit cover 41 is formed, for example, by bending a single metal plate. A through hole 410 through which the lens 400 passes is provided in the center of the unit cover 41.

[0081] The emergency light source section 4a is attached to the recessed section 24 by hooking a part of the unit cover 41 onto the pair of first wall sections 21 of the fixture body 2.

[0082] (2.4) Heat shielding material 3 and 4 is disposed between the light source unit 31 and the battery 6. More specifically, the heat shield 9 is attached to the left end of the support member 30 at a position overlapping with the battery 6 in the front-rear direction.

[0083] The heat shielding member 9 prevents radiant heat from the light source unit 31 from being transmitted to the battery 6. In this embodiment, the heat shielding member 9 has a higher thermal conductivity than the support member 30 and is made of, for example, aluminum.

[0084] The heat-shielding member 9 has a plate-shaped main body 90, a plate-shaped fixing piece 91 protruding forward from one end (upper end) of the main body 90, and an L-shaped locking piece 92 in a side view protruding forward from the other end (lower end) of the main body 90.

[0085] A fixing hole 910 is provided in a part of the fixing piece 91, into which a fixing tool 12 for fixing the cover 32 to the support member 30 is fixed.

[0086] The locking piece 92 has a rectangular, flat first portion 920 protruding forward from the lower end of the main body 90, and a rectangular, flat second portion 921 extending downward from the tip (front end) of the first portion 920.

[0087] 4 and 5, the heat shield 9 is attached to the support member 30 by inserting the locking piece 92 into the gap between the curved portion 3022 and the second surface S2 of the main body portion 300 and fixing the fixing piece 91 to the member-side fixing portion 301 of the support member 30 with a fastener 12. The heat shield 9 is attached to one end (e.g., the left end) in the longitudinal direction of the support member 30 that overlaps with the battery 6 in the front-rear direction.

[0088] (2.5) Human detection unit 1 and 2 is configured to output a human detection signal to the control unit 33 of the light source unit 3 when it detects a human (moving object). The human detection unit 5 is, for example, a radio wave sensor.

[0089] The human detection unit 5 is attached to the center of the second lower wall portion 22 in the left-right direction.

[0090] (3) Effects In the lighting fixture 1 of the present embodiment described above, the cover 32 is attached to the support member 30 as follows.

[0091] First, the cover 32 is fitted onto the supporting member 30 in a state in which the rib R1 of the cover-side fixing portion 325 and the rib R2 of the contact portion 326 are in contact with the member-side fixing portion 301 and the flat portion 3021 of the hook portion 302 of the supporting member 30, respectively.

[0092] 3 and 4, in a state where the cover 32 is fitted into the support member 30, the multiple insertion holes 3251 of the cover-side fixing part 325 and the multiple fixing holes 304 of the member-side fixing part 301 are overlapped in the vertical direction. In this state, the fixing devices 11 and 12 are inserted into the multiple insertion holes 3251 and fixed to the multiple fixing holes 304, whereby the member-side fixing part 301 and the cover-side fixing part 325 are fixed by the fixing devices 11 and 12. The member-side fixing part 301 and the cover-side fixing part 325 may be fixed by a method such as crimping.

[0093] 5, when the cover 32 is fitted into the support member 30, the insertion hole H1 of the planar portion 3021 and the insertion hole H2 of the planar contact portion 3260 overlap in the vertical direction. In this state, the fastener 13 is inserted into the insertion holes H1 and H2 from below, and the fastener 13 is fixed to the insertion hole H1, thereby fixing the planar portion 3021 and the planar contact portion 3260 to each other by the fastener 13. The planar portion 3021 and the planar contact portion 3260 may be fixed to each other by a method such as crimping.

[0094] Next, the cover ends 321 are attached to the left and right ends of the cover body 320 .

[0095] In this way, the flat surface portion 3021 of the hook portion 302 functions as a guide in the operation of attaching the cover 32 to the support member 30, thereby improving the ease of assembly.
