[0010] A lighting device 1 according to an embodiment of the present disclosure will be described in detail with reference to the drawings. Note that each figure described in the following embodiment is a schematic diagram, and the size and thickness ratio of each component in each figure does not necessarily reflect the actual dimensional ratio. In addition, the embodiment and modified example described below are merely examples of the present disclosure, and the present disclosure is not limited to the embodiment and modified example. Even if it is not the embodiment and modified example, various modifications are possible according to the design, etc., as long as it does not deviate from the technical idea of ​​the present disclosure. In addition, the following embodiment (including modified examples) may be realized by appropriately combining them.

[0011] (1) Overview As shown in FIGS. 1 to 4, the lighting device 1 includes a light source section 31, a support member 30 that supports the light source section 31, and a cover 32 that is attached to the support member 30 so as to cover the light source section 31.

[0012] The support member 30 has a main body portion 300 which is a plate-like body extending in one direction, and a first hook portion 302 which is connected to one end of the main body portion 300 in the width direction (the lower end D1 in this embodiment).

[0013] The first hook portion 302 has a curved portion 3021 having a first end E1 connected to one widthwise end (lower end D1) of the main body portion 300 and a second end E2 different from the first end E1, and a flat portion 3022 connected to the second end E2 of the curved portion 3021.

[0014] The main body 300 has a first surface S1 and a second surface S2 that face each other in the thickness direction.

[0015] The main body 300 supports the light source unit 31 on the first surface S1.

[0016] The curved portion 3021 is curved so as to be convex in the opposite direction relative to the main body portion 300 when viewed from one direction.

[0017] The flat surface portion 3022 faces the second surface S2 in the thickness direction via a space Sp1.

[0018] The cover 32 has a second hook portion 326 that hooks onto at least a portion of the first hook portion 302 .

[0019] Here, the expression "curved portion 3021 is convex in the opposite direction to main body portion 300" means that curved portion 3021 is convex in the opposite direction to the direction of main body portion 300 as seen from curved portion 3021.

[0020] According to the above configuration, the flat portion 3022 connected to the main body 300 via the curved portion 3021 faces the second surface S2 via the space Sp1 in the thickness direction, so that the space Sp1 can be effectively utilized. This allows some of the components of the lighting device 1 (for example, the power supply line 8 that supplies power from a power source to the light source unit 31) to be accommodated in the space Sp1, and the lighting device 1 can be made compact.

[0021] (2) Details The lighting fixture 1 will now be described in detail with reference to the drawings.

[0022] In this embodiment, the lighting fixture 1 is a lighting fixture (a so-called staircase passageway exit light) that is installed on a wall surface 100 of a landing of a staircase that serves as an evacuation route of a building.

[0023] The lighting fixture 1 is an elongated lighting fixture that extends in one direction. In the following description, the up-down, left-right, and front-rear directions of the lighting fixture 1 are defined based on the state in which the lighting fixture 1 shown in Fig. 1 is installed on a wall surface 100. That is, the direction in which the lighting fixture 1 is located relative to the wall surface 100 is defined as the front, and among the directions along the wall surface 100, the longitudinal direction of the lighting fixture 1 is defined as the left-right direction, and the transverse direction of the lighting fixture 1 is defined as the up-down direction. That is, in this embodiment, the lighting fixture 1 extends in the left-right direction.

[0024] 1, the lighting fixture 1 includes a fixture body 2 extending in the left-right direction, a light source unit 3 extending in the left-right direction, function units 4 disposed on the left and right of the light source unit 3, and a human detection unit 5.

[0026] The pair of second wall portions 22 extend obliquely upward and backward and obliquely downward and backward from the tip ends (front end portions) of the pair of first wall portions 21 so as to face the pair of first wall portions 21, respectively.

[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 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.

[0031] The bottom 20, the pair of first walls 21, and the pair of second walls 22 have the same length in the left-right direction. The bottom 20, the pair of first walls 21, and the pair of second walls 22 are integrally formed, for example, by bending a single metal plate. In this embodiment, the pair of third walls 23 are formed by bending a metal plate different from the bottom 20, the pair of first walls 21, and the pair of second walls 22.

[0032] 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.

[0033] 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.

[0034] A power supply line 8 that supplies power from a power source to the light source unit 3 can be inserted into each of the multiple introduction holes 27. The power supply line 8 is introduced into the recess 24 through the introduction hole 27.

[0035] 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.

[0038] 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.

[0039] 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.

[0040] 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.

[0041] (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.

[0042] 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.

[0043] 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.

[0044] 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 below. More specifically, the control unit 33 controls the power supplied to the light source unit 31 from a power source (e.g., a commercial AC 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.

[0045] 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 first 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 first hook portion 302 is connected, for example, to a lower end D1 of the main body 300.

[0046] 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.

[0047] The main body 300 supports the light source unit 31 on the first surface S1.

[0048] As shown in FIG. 4, the first hook portion 302 has a curved portion 3021 and a flat portion 3022.

[0049] The curved portion 3021 has a first end E1 connected to the lower end D1 of the main body portion 300, and a second end E2 different from the first end E1.

[0050] When viewed from the left-right direction, the curved portion 3021 is curved so as to be convex in the opposite direction to the main body portion 300. More specifically, the curved portion 3021 is curved so as to be convex downward, which is the opposite direction to the upward direction of the main body portion 300 as viewed from the curved portion 3021.

[0051] The curved portion 3021 has a constant curvature when viewed from the left-right direction. That is, the shape of the curved portion 3021 when viewed from the left-right direction is an arc. More specifically, the shape of the curved portion 3021 when viewed from the left-right direction is, for example, a semicircular shape.

[0052] The flat portion 3022 has a plate shape extending in the left-right direction. The flat portion 3022 has a third end E3 connected to the second end E2 of the curved portion 3021 and a fourth end E4 different from the third end E3. In this embodiment, the third end E3 is the lower end of the flat portion 3022, and the fourth end E4 is the upper end of the flat portion 3022.

[0053] As shown in FIG. 4, the flat surface portion 3022 is provided with a plurality of insertion holes H1 through which fasteners 13 such as screws are inserted.

[0054] The flat surface portion 3022 faces a second surface S2, which is the rear surface of the main body portion 300, across a space Sp1 in the front-rear direction.

[0055] The power supply line 8 is housed in the space Sp1.

[0056] Here, the distance Ds between the flat surface portion 3022 and the second surface S2 in the front-rear direction is, for example, constant. That is, the flat surface portion 3022 and the second surface S2 are parallel to each other. In this disclosure, "parallel" is not limited to parallel in the strict sense, and also includes cases where there is an error within an allowable range.

[0057] 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 of the main body portion 300 opposite to the lower end D1.

[0058] The component side fixing portion 301 is a long rectangular flat plate extending in the left-right direction.

[0059] The component-side fixed part 301 protrudes slightly rearward from the first hook part 302. In other words, the rear end of the component-side fixed part 301 is located rearward from the rear end of the first hook part 302.

[0060] 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.

[0061] 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.

[0062] 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.

[0063] 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.

[0064] 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.

[0065] The cover side fixing part 325 is a flat plate extending in the left-right direction so as to follow at least a part of the member side fixing part 301 of the support member 30. A plurality of ribs 3250 (two in this embodiment) are provided on the lower surface of the cover side fixing part 325. The cover side fixing part 325 is also provided with a plurality of insertion holes 3251 through which the fixing devices 11, 12 are inserted.

[0066] Additionally, the cover body 320 has a second hook portion 326 that protrudes rearward from the center of the lower flange portion 324 in the up-down direction.

[0067] The second hook portion 326 has a flat protrusion 3260 that protrudes rearward from the lower flange portion 324, and a curved contact portion 3261 that is continuous with the protrusion 3260 and is curved in an arc shape along a portion of the curved portion 3021 of the first hook portion 302.

[0068] Further, the second hook portion 326 further has a planar contact portion 3262 that is continuous with the curved contact portion 3261. The planar contact portion 3262 is in the form of a plate that extends in the left-right direction along the planar portion 3022 of the first hook portion 302.

[0069] As shown in FIG. 4, the flat contact portion 3262 is provided with a plurality of insertion holes H2 through which the fixtures 13 are inserted.

[0070] 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.

[0071] 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.

[0072] 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 .

[0073] The above-mentioned cover 32 and support member 30 can be attached as follows.

[0074] First, the first hook portion 302 of the support member 30 is inserted into the second hook portion 326 of the cover body 320 in a state in which the body portion 322 of the cover body 320 and the body portion 300 of the support member 30 are slightly tilted from a parallel state.

[0075] Next, the cover body 320 is rotated around the first hook portion 302 of the support member 30, and the cover body 320 is moved to a position where the body portion 322 of the cover body 320 and the body portion 300 of the support member 30 are parallel to each other.

[0076] When the main body 322 of the cover main body 320 and the main body 300 of the support member 30 are parallel to each other, the flat surface 3022 of the first hook portion 302 and the flat surface contact portion 3262 of the second hook portion 326 come into contact with each other along the left-right direction. At this time, the insertion hole H1 of the flat surface 3022 and the insertion hole H2 of the flat surface contact portion 3262 overlap with each other in the front-rear direction.

[0077] Here, the fastener 13 is inserted into the insertion holes H1 and H2 from the rear, and the tip of the fastener 13 is fixed to a fixing member such as a nut, thereby fixing the flat surface portion 3022 and the flat surface contact portion 3262 with the fastener 13. If a thread groove is formed in the insertion hole H1, a fixing member is not necessary. Also, the flat surface portion 3022 and the flat surface contact portion 3262 may be fixed by a method such as crimping.

[0078] Furthermore, when the main body 322 of the cover body 320 and the main body 300 of the support member 30 are parallel to each other, the rib 3250 of the cover-side fixing part 325 of the cover body 320 and the member-side fixing part 301 of the support member 30 come into contact with each other along the left-right direction. At this time, 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 overlap in the up-down direction.

[0079] Here, the fasteners 11, 12 are inserted into the multiple insertion holes 3251, and the fasteners 11, 12 are fixed to the multiple fixing holes 304, whereby the component side fixing part 301 and the cover side fixing part 325 are fixed by the fasteners 11, 12. The component side fixing part 301 and the cover side fixing part 325 may be fixed by a method such as crimping.

[0080] Next, the cover ends 321 are attached to the left and right ends of the cover body 320 .

[0081] In this manner, the cover 32 is attached to the support member 30.

[0082] (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.

[0083] The pair of emergency light source units 4a are housed one at each of both longitudinal ends (that is, the left and right ends) of the recess 24.

[0084] 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.

[0085] As shown in FIG. 2, each emergency light source unit 4a includes an emergency LED module 40 and a unit cover 41.

[0086] 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.

[0087] 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.

[0088] 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.

[0089] 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.

[0090] (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.

[0091] 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.

[0092] (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.

[0093] The human detection unit 5 is attached to the center of the second lower wall portion 22 in the left-right direction.

[0094] (3) Effects In the lighting device 1 of the present embodiment described above, the planar portion 3022 faces the second surface S2 of the main body portion 300 in the front-to-rear direction via the space Sp1, and some of the components of the lighting device 1, such as the power supply line 8, can be accommodated within the space Sp1.

[0095] As a result, there is no need to reserve a large space (for example, space 25 surrounded by a pair of first wall portions 21 and a pair of second wall portions 22 and opening toward the rear of the fixture body 2) to accommodate some of the components of the lighting fixture 1, making it possible to make the lighting fixture 1 more compact.

[0096] (4) Variations The above embodiment is merely one of various embodiments of the present disclosure. The above embodiment can be modified in various ways depending on the design, etc., as long as the object of the present disclosure can be achieved. Below, modifications of the above embodiment are listed. The modifications described below can be applied in appropriate combination.

[0097] In the above embodiment, the curvature of the curved portion 3021 of the first hook portion 302 is constant when viewed from the left-right direction, but the curvature of the curved portion 3021 may change when viewed from the left-right direction. When the curvature of the curved portion 3021 changes, the curved portion 3021 becomes parabolic, for example, as shown in Fig. 5. Note that the shape of the curved portion 3021 when the curvature of the curved portion 3021 changes is not limited to a parabolic shape, and may be any curve other than a circular arc.

[0098] In the above embodiment, the distance Ds between the flat portion 3022 and the second surface S2 in the front-rear direction is constant, but as shown in Fig. 6, the distance Ds may increase toward the upper end U1 opposite the lower end D1 of the main body portion 300.
