(Embodiment 1)
FIG. 1 is a perspective view showing a lighting fixture 1 according to Embodiment 1 of the present invention. As shown in FIG. 1, the luminaire 1 includes a light source unit 3 and a base unit 5.

  The light source unit 3 emits light. The light source unit 3 is attached to the base unit 5. The light source unit 3 extends along a certain direction PD. In the first embodiment, the direction PD indicates the first direction FD or the second direction SD. The first direction FD is substantially parallel to the positive direction of the Y axis. The second direction SD is the reverse direction of the first direction FD.

  The base unit 5 extends along the direction PD and is attached to a mounting portion in a structure such as a building. In the first embodiment, the attachment portion is a ceiling surface of a room in a building.

  FIG. 2 is a perspective view showing the light source unit 3, the base unit 5, and the clamping member 100 of the lighting fixture 1. FIG. 3 is a perspective view showing the base unit 5 and the clamping member 100.

  As shown in FIGS. 2 and 3, the base unit 5 includes a recess 110. The recess 110 extends along the direction PD and has a groove shape. The concave portion 110 has a substantially U-shaped cross section, and includes a top wall portion 110a and a pair of side wall portions 110b facing each other. The top wall portion 110a and the pair of side wall portions 110b extend along the direction PD. A through hole 116 for introducing a power supply line from the ceiling is formed at a substantially center in the longitudinal direction of the top wall portion 110a.

  The light source unit 3 includes a power supply unit 84 that supplies power to the light source unit. The power supply unit 84 is disposed at a position closer to the center in the longitudinal direction of the light source unit 3 than one end portion of the pair of end portions in the longitudinal direction of the light source unit 3. Specifically, the power supply unit 84 is disposed in the vicinity of the through hole 116. The power supply unit 84 is supplied with an external power supply voltage from the power supply line introduced from the through hole 116 via the terminal block.

  The light source unit 3 includes two engaged portions 85 that face each other. Specifically, the power supply unit 84 includes two engaged portions 85. In FIG. 2, only one engaged portion 85 of the two engaged portions 85 appears. One engaged portion 85 of the two engaged portions 85 is formed on a surface of the power supply unit 84 that faces the surface on which the other engaged portion 85 is formed. The two engaged portions 85 are arranged along the short direction of the light source unit 3. Specifically, the two engaged portions 85 are disposed so as to be positioned between the two side wall portions 110 b when the light source unit 3 is attached to the base unit 5. According to the first embodiment, since the engaged portion 85 is formed in the power source portion 84, it is not required to prepare the engaged portion 85 as a dedicated member, and the number of parts and the number of assembly steps can be reduced.

  The luminaire 1 further includes a clamping member 100 as a clamping unit. The clamping member 100 is substantially U-shaped, has elasticity, and is, for example, a metal leaf spring. The clamping member 100 is attached to the recess 110. Specifically, the clamping member 100 is attached to the top wall portion 110a. The sandwiching member 100 is disposed at a position closer to the center in the longitudinal direction of the base unit 5 than one end portion of the pair of end portions in the longitudinal direction of the base unit 5. Specifically, the clamping member 100 is disposed in the vicinity of the through hole 116.

  When the light source unit 3 is pushed into the recess 110 in the direction of arrow A, the clamping member 100 clamps the light source unit 3 in the recess 110. As a result, the light source unit 3 is attached to the base unit 5. According to the first embodiment, the operator can easily attach the light source unit 3 to the base unit 5 by fitting the light source unit 3 into the holding member 100 and holding the light source unit 3 in the holding member 100.

  Specifically, the clamping member 100 clamps the power supply unit 84 in the recess 110. Therefore, according to the first embodiment, it is not required to prepare the sandwiched member sandwiched by the sandwiching member 100 as a dedicated member, and the number of parts and the number of assembly steps can be reduced. Further, by sandwiching the relatively heavy power supply unit 84, the light source unit 3 can be prevented from being bent by its own weight. Furthermore, since the power supply part 84 protrudes toward the recessed part 110, the light source unit 3 can be attached to the base unit 5 more easily.

  With reference to FIG.2 and FIG.4, the detail of the clamping member 100 is demonstrated. 4A and 4B are perspective views showing the holding member 100. FIG. FIG. 4C is a cross-sectional view showing the holding member 100. As shown in FIGS. 4A to 4C, the clamping member 100 includes two engaging portions 10 and a connecting portion 18. The connecting portion 18 has a substantially plate shape and connects the two engaging portions 10. Two through holes 20 are formed in the connecting portion 18. A screw is screwed into the top wall 110 a of the recess 110 through the through hole 20, and the clamping member 100 is attached to the recess 110.

  The two engaging parts 10 correspond to the two engaged parts 85 of the power supply part 84. Each of the engaging portions 10 engages with a corresponding engaged portion 85. As a result, the power supply unit 84 is sandwiched. According to Embodiment 1, since the engaging part 10 engages with the engaged part 85, the position of the light source unit 3 can be prevented from shifting in the first direction FD or the second direction SD. For example, the position of the light source unit 3 can be prevented from shifting in the horizontal direction. In addition, it is possible to suppress the position of the light source unit 3 from shifting in the direction intersecting the direction PD. For example, it is possible to suppress the position of the light source unit 3 from shifting in the vertical direction.

  The two engaging portions 10 are formed so as to be opposed to each other and symmetrical with respect to an axis of symmetry AX passing through the connecting portion 18. Each of the engaging portions 10 includes a base portion 11, a first inclined portion 12, a second inclined portion 14, and a sliding contact portion 15.

  The pair of base portions 11 are substantially plate-shaped and extend substantially vertically from the pair of end portions of the connecting portion 18. The pair of first inclined portions 12 are substantially plate-shaped, extend from the tip portions of the pair of base portions 11 so as to approach each other, and are inclined with respect to the base portion 11. The pair of second inclined portions 14 are substantially plate-shaped, extend away from the distal ends of the pair of first inclined portions 12, and are inclined with respect to the first inclined portion 12. The first inclined portion 12 and the second inclined portion 14 form a convex portion 22. The convex portion 22 is substantially V-shaped in cross-sectional view. The pair of convex portions 22 protrude in directions facing each other, and engage with the pair of engaged portions 85 of the power supply unit 84.

  The pair of sliding contact portions 15 are substantially plate-shaped, extend from the side end portions of the pair of second inclined portions 14 so as to be separated from each other, and are inclined with respect to the second inclined portion 14. The sliding contact portion 15 is bent from the side end portion of the second inclined portion 14 so as to approach the side end portion 24 of the first inclined portion 12. Then, when the light source unit 3 slides in the second direction SD and is removed from the base unit 5, the sliding contact portion 15 comes into sliding contact with the engaged portion 85. Therefore, compared with the case where the sliding contact portion 15 is not provided, the engaging portion 10 is smoothly detached from the engaged portion 85. As a result, according to the first embodiment, the light source unit 3 can be easily detached from the base unit 5.

  With reference to FIG. 5, the detail of the lighting fixture 1 is demonstrated. FIG. 5 is an exploded perspective view showing the luminaire 1.

  The light source unit 60 extends along the direction PD, and includes a plurality of LEDs (Light Emitting Diodes) 62 that emit light and a substrate 64. The plurality of LEDs 62 are linearly arranged and mounted on the mounting surface 64 a of the substrate 64.

  The base member 70 extends along the direction PD and has a substantially U-shaped cross section. The base member 70 has a bottom wall portion 72 and a pair of side wall portions 74 facing each other. The light source unit 60 is attached to the base member 70 so that the lower surface 72a of the bottom wall 72 and the surface opposite to the mounting surface 64a of the substrate 64 face each other.

  The pair of hooks 80 are disposed on the upper surface of the bottom wall portion 72 and are fixed to the pair of end portions in the longitudinal direction of the base member 70. The hook metal fitting 80 has a hook-shaped tip. The pair of hooks 80 are hooked on the base unit 5.

  The power supply unit 84 supplies power to the light source unit 60. Specifically, the power supply unit 84 includes a power supply circuit unit 84a and a metal case 84b that houses the power supply circuit unit 84a. Case 84b includes a pair of side wall portions 84c facing each other. The power supply circuit unit 84 a supplies power for turning on the LEDs 62 to the LEDs 62 based on the external power supply voltage. The power supply circuit portion 84a is attached to the inner upper surface of the case 84b. The case 84 b is attached to the upper surface of the bottom wall portion 72 of the base member 70. As a result, the power supply unit 84 is attached to the base member 70.

  A pair of engaged portions 85 are formed on the pair of side wall portions 84c of the case 84b. FIG. 5 shows only one engaged portion 85 of the pair of engaged portions 85.

  As shown in FIG. 5, the base unit 5 of the luminaire 1 further includes a pair of extending portions 112, a pair of end members 114, and a temporary suspension portion 117 in addition to the recess 110. In Embodiment 1, the recessed part 110 and the extending part 112 are formed by bending a steel plate.

  The extending portion 112 extends along the recessed portion 110. The extension 112 is bent from the recess 110 toward the outside of the recess 110 so as to form an acute angle with the side wall 110b. The inclined surface of the extending portion 112 is preferably subjected to a reflection process such as white coating in order to efficiently reflect the light emitted from the light source unit 3.

  The pair of end members 114 constitute a pair of end portions in the longitudinal direction of the base unit 5. A pair of hooks 80 are hooked on the backs of the pair of end members 114. As a result, the light source unit 3 is supported by the pair of end members 114.

  The temporary suspension part 117 has a through hole, and is formed in the top wall part 110 a in the vicinity of the end member 114.

  With reference to FIGS. 6-8, the clamping member 100 when the clamping member 100 is clamping the light source unit 3 is demonstrated. 6 is a cross-sectional view taken along line VI-VI in FIG. FIG. 7A is an enlarged cross-sectional view showing the engaging portion 10 and the engaged portion 85 included in the region EA of FIG. The configurations of the other engaging portion 10 and the engaged portion 85 that are not included in the region EA are the same as the configurations of the engaging portion 10 and the engaged portion 85 that are included in the region EA, and a description thereof is omitted. FIG. 7B is a perspective view showing the engaging portion 10 and the engaged portion 85. In FIG.7 (b), the to-be-engaged part 85 is shown with the dashed-two dotted line for simplification of drawing.

  As shown in FIG. 6, the elastic force of the clamping member 100 acts toward the power supply unit 84. Therefore, the clamping member 100 clamps the power supply unit 84 by tightening the power supply unit 84 with the pair of engaging units 10 and engaging the pair of engaged units 85 with the pair of engaging units 10. As a result, the light source unit 3 is attached to the base unit 5. Specifically, as shown in FIGS. 7A and 7B, the engaged portion 85 has a substantially rectangular through hole 85a. And the convex part 22 of the engaging part 10 engages with the through-hole 85a. The sliding contact portion 15 of the engaging portion 10 is inclined so as to be separated from the engaged portion 85.

  As shown in FIG. 6, the cover member 40 includes a pair of base portions 42, a pair of side wall portions 44, and a pair of raised portions 46. Each of the pair of base portions 42 extends along the direction PD (FIG. 5). The upper surface of the base part 42 is flat. The pair of side wall portions 44 face each other and extend along the direction PD. The side wall portion 44 stands substantially vertically from the upper surface of the base portion 42. The pair of raised portions 46 protrude from the upper surfaces of the pair of base portions 42 so as to sandwich the pair of side wall portions 44, and extend along the direction PD. The light source unit 3 is attached to the base unit 5 such that the pair of side wall portions 44 and the pair of raised portions 46 are disposed between the pair of side wall portions 110b. The base member 70 to which the power supply unit 84 and the light source unit 60 are attached is held by the pair of base units 42 and the pair of side wall units 44. 6 and 7A, the power supply circuit portion 84a is omitted for simplification of the drawings.

  8 is a cross-sectional view taken along line VIII-VIII in FIG. In FIG. 8, for the sake of simplification of the drawing, oblique lines indicating the cross section are omitted.

  As shown in FIG. 8, the clamping member 100 has a light source unit 3 (specifically, a position closer to the center of gravity G of the light source unit 3 than one end portion of the pair of end portions in the longitudinal direction of the light source unit 3. The power supply unit 84) is clamped. Therefore, according to the first embodiment, it is possible to further suppress the light source unit 3 from being bent by its own weight. In particular, the clamping member 100 preferably clamps the light source unit 3 (specifically, the power supply unit 84) in the vicinity of the center of gravity G of the light source unit 3.

  As shown in FIG. 8, each end member 114 includes a support portion 120 and a stopper 122. And the front-end | tip part of a pair of hook metal fitting 80 contact | abuts to a pair of support part 120. FIG. Accordingly, the light source unit 3 is supported by the pair of support portions 120. Further, the stopper 122 suppresses the hook member 80 from being detached from the end member 114.

  A procedure for attaching the light source unit 3 to the base unit 5 will be described with reference to FIGS. 9 and 10. FIG. 9 is a perspective view showing the previous stage of the procedure for attaching the light source unit 3 to the base unit 5.

  Since the sliding contact portion 15 of the engaging portion 10 is inclined so as to be separated from the engaged portion 85, the light source unit 3 is slid in the second direction SD to move the engaging portion 10 from the engaged portion 85. When removed, the sliding contact portion 15 comes into sliding contact with the edge 85 b of the through hole 85 a of the engaged portion 85. Therefore, compared with the case where the sliding contact portion 15 is not provided, the engaging portion 10 is smoothly detached from the engaged portion 85. As a result, the light source unit 3 can be easily detached from the base unit 5.

  As described above with reference to FIGS. 1 to 10, according to the first embodiment, the light source unit 3 can be easily attached by providing the clamping member 100.

(Embodiment 2)
With reference to FIG.1 and FIG.11-FIG. 13, the lighting fixture 1 which concerns on Embodiment 2 of this invention is demonstrated. The structure of the lighting fixture 1 which concerns on Embodiment 2 is the same as that of the lighting fixture 1 which concerns on Embodiment 1 demonstrated with reference to FIG. However, the luminaire 1 according to the second embodiment includes a clamping unit 100a instead of the clamping member 100 according to the first embodiment. The second embodiment is different from the first embodiment in which the clamping member 100 is attached to the base unit 5 in that the clamping part 100 a is attached to the light source unit 3. Hereinafter, a configuration in which the second embodiment is different from the first embodiment will be mainly described.

  The detail of the clamping part 100a is demonstrated with reference to FIG. Fig.11 (a) is a perspective view which shows the clamping part 100a. FIG.11 (b) is sectional drawing which shows the clamping part 100a. 11A and 11B show an arrangement when the clamping unit 100a is attached to the light source unit 3. FIG.

  As shown in FIGS. 11A and 11B, the clamping unit 100 a includes two engaging units 10. The two engaging portions 10 are formed so as to face each other and be symmetric. Each of the engaging portions 10 includes a base portion 11, a first inclined portion 12, a second inclined portion 14, and a sliding contact portion 15.

  Each of the pair of base portions 11 has a substantially plate shape. A through hole 20 is formed in the base 11. A screw is screwed into the side wall portion 84 c of the power supply portion 84 through the through hole 20, and the clamping portion 100 a is attached to the power supply portion 84. In the second embodiment, the engaged portion 85 is formed not on the power supply portion 84 but on the base unit 5.

  The pair of first inclined portions 12 are substantially plate-shaped, extend away from the tip portions of the pair of base portions 11, and are inclined with respect to the base portion 11. The pair of second inclined portions 14 is substantially plate-shaped, extends from the tip portions of the pair of first inclined portions 12 so as to approach each other, and is inclined with respect to the first inclined portion 12. The first inclined portion 12 and the second inclined portion 14 form a convex portion 22. The convex portion 22 is substantially V-shaped in cross-sectional view. The pair of convex portions 22 protrude in opposite directions (directions away from each other).

  The pair of sliding contact portions 15 is substantially plate-shaped, extends from the side end portions of the pair of first inclined portions 12 so as to approach each other, and is inclined with respect to the first inclined portion 12. The sliding contact portion 15 is bent from the side end portion of the first inclined portion 12 so as to approach the side end portion 25 of the second inclined portion 14.

  With reference to FIG.12 and FIG.13, the clamping part 100a when the clamping part 100a is clamping the light source unit 3 is demonstrated. FIG. 12 is a cross-sectional view showing the luminaire 1. FIG. 13A is an enlarged cross-sectional view showing the engaging portion 10 and the engaged portion 85 included in the region EA of FIG. The configurations of the other engaging portion 10 and the engaged portion 85 that are not included in the region EA are the same as the configurations of the engaging portion 10 and the engaged portion 85 that are included in the region EA, and a description thereof is omitted. FIG. 13B is a perspective view showing the engaging portion 10 and the engaged portion 85.

  As shown in FIGS. 12, 13 (a), and 13 (b), the base unit 5 includes two engaged portions 85. Specifically, a pair of engaged portions 85 are formed on the pair of side wall portions 110 b of the recess 110. Each of the engaged portions 85 includes a substantially rectangular through hole 85a. According to the second embodiment, since the engaged portion 85 is formed in the recess 110, it is not required to prepare the engaged portion 85 as a dedicated member, and the number of parts and the number of assembly steps can be reduced.

  The two engaging portions 10 correspond to the two engaged portions 85. Each of the engaging portions 10 engages with a corresponding engaged portion 85. Specifically, the convex portion 22 engages with the through hole 85a. According to Embodiment 2, since the engaging part 10 engages with the engaged part 85, the position of the light source unit 3 can be suppressed from shifting in the first direction FD or the second direction SD. In addition, it is possible to suppress the position of the light source unit 3 from shifting in the direction intersecting the direction PD.

  Moreover, the elastic force of the engaging part 10 acts toward the side wall part 110b. Therefore, the clamping part 100a tightens the light source unit 3 (specifically, the power supply part 84) with the pair of engaging parts 10 and engages the pair of engaged parts 85 with the pair of engaging parts 10. The light source unit 3 (specifically, the power supply unit 84) is sandwiched. As a result, the light source unit 3 is attached to the base unit 5. According to the second embodiment, the operator can easily attach the light source unit 3 to the base unit 5 by fitting the light source unit 3 into the recess 110 and holding the light source unit 3 between the holding members 100.

  Further, the sliding contact portion 15 of the engaging portion 10 is inclined so as to be separated from the engaged portion 85. Therefore, when the light source unit 3 slides in the second direction SD and is removed from the base unit 5, the sliding contact portion 15 comes into sliding contact with the engaged portion 85.
