Similarly, in the other (right) reflector 24, the flat portion 240 protrudes outward (the opposite side to the storage section 20) from the other (right) sidewall portion 211, and the inclined portion 241 protrudes obliquely downward from the tip of the flat portion 240. In addition, a reinforcing piece 242 protruding upward is provided at the tip of each inclined portion 241.

[0023] (End parts) 3, the pair of end members 3 are provided on both ends of the main body portion 200 along the one direction. That is, the pair of end members 3 are provided on one end (front end) and the other end (rear end) in the longitudinal direction of the main body portion 200, respectively. At least one of the pair of end members 3 is attached to the main body portion 200 so as to be slidable along the one direction. In this embodiment, both end members 3 are attached to the main body portion 200 so as to be slidable along the front-rear direction.

[0024] The end member 3 is formed by forming a metal plate such as a steel plate by sheet metal processing or the like. As shown in Fig. 4 and Fig. 5, the end member 3 includes a main portion 301, a rising portion 302, a protruding piece 30, and a cover portion 303. The main portion 301 is a portion formed in a substantially trapezoidal shape when viewed from the front or rear.

[0025] The rising portion 302 is formed in approximately the center of the main portion 301 in the left-right direction, protruding upward from the upper end of the main portion 301. The rising portion 302 is formed in a generally trapezoidal shape when viewed from the front or rear, and is formed in a generally flat plate shape with the front-to-rear direction as the thickness direction. A narrow width portion 304 is provided at the upper end of the rising portion 302. The narrow width portion 304 is formed in approximately the center of the rising portion 302 in the left-right direction. The narrow width portion 304 is formed to have a smaller dimension in the left-right direction than other portions of the rising portion 302.

[0026] The protruding piece 30 is a portion that overlaps with the wall portion 21 of the storage section 20. The protruding piece 30 is provided at the upper end of the rising portion 302. The protruding piece 30 protrudes from the upper end of the narrow width portion 304 of the rising portion 302 toward the center in the front-to-rear direction of the main body portion 200. The protruding piece 30 protrudes approximately at a right angle to the front and rear surfaces of the main portion 301 and the rising portion 302. The protruding piece 30 is formed in a substantially rectangular plate shape when viewed from above.

[0027] A fixing portion 305 is provided at the tip of the protruding piece 30 (the end opposite to the narrow portion 304). The fixing portion 305 is a screw hole to which a fastener 31 such as a screw is coupled. The fixing portion 305 is formed in approximately the center in the left-right direction of the protruding piece 30. The fixing portion 305 penetrates the protruding piece 30 in the up-down direction (thickness direction).

[0028] The end member 3 has an insertion piece 32 that restricts the rotation of the end member 3 relative to the main body 200. The insertion piece 32 is formed at the tip of the protruding piece 30. The insertion piece 32 is formed to protrude downward from the lower surface of the protruding piece 30. The insertion piece 32 is formed by forming a notch in the protruding piece 30 and cutting and raising a part of the protruding piece 30. The insertion piece 32 protrudes at a substantially right angle to the lower surface of the protruding piece 30. A pair of insertion pieces 32 is provided. The pair of insertion pieces 32 is provided on both the left and right sides of the fixing part 305. The distance between the pair of insertion pieces 32 is substantially equal to the distance between the pair of slits 25 formed in the upper wall part 210 of the main body 200.

[0029] In this embodiment, the pair of slits 25 and the pair of insertion pieces 32 form a rotation stopper 300 that restricts the rotation of the end member 3 relative to the main body portion 200 (see FIGS. 6 and 8).

[0030] The cover portion 303 is formed at the lower end of the main portion 301. The cover portion 303 is provided over the entire length in the left-right direction of the lower end of the main portion 301. The cover portion 303 includes an extension portion 306 that protrudes outward (the opposite side to the protruding direction of the protruding piece 30) from the lower end of the main portion 301, and a protruding piece 307 that protrudes upward from the tip of the extension portion 306.

[0031] (Mounting legs) The lighting fixture 1A of this embodiment includes a pair of mounting legs 4. The pair of mounting legs 4 are attached to the fixture body 2 side by side in the front-to-rear direction. The mounting legs 4 are provided so as to straddle the main body 200 of the fixture body 2 in the left-right direction. The mounting legs 4 are fixed at approximately the center in the left-right direction to the upper wall 210 of the main body 200.

[0032] The pair of mounting legs 4 are used when mounting the lighting fixture 1A to a system ceiling. The mounting legs 4 have holding parts 40 at both left and right ends. As shown in FIG. 10, the holding parts 40 are attached to a T-bar 6 constituting the system ceiling. The T-bar 6 is attached to each of a plurality of hanging bolts embedded in the ceiling slab of the building. A joint part 61 is provided at the upper end of the T-bar 6, and the T-bar 6 is arranged by joining the hanging bolts to the joint part 61. The holding part 40 is formed in a substantially L-shaped cross section, and both ends of the mounting legs 4 are held by the T-bar 6 by placing the holding part 40 on the joint part 61 from above. In addition, the mounting legs 4 are provided with locking pieces 41 protruding diagonally upward at both left and right ends, and the locking pieces 41 are hooked on the undersides of the joint parts 61, thereby holding the mounting legs 4 to the T-bar 6.

[0033] The T-bar 6 has a vertical piece 62 that protrudes downward from the joint 61. The T-bar 6 also has a support piece 63 that protrudes in the left-right direction from the lower end of the vertical piece 62. A system ceiling is formed by placing the peripheral end of the ceiling panel on the support piece 63 of the T-bar 6. The lighting fixture 1A of this embodiment is also attached to the system ceiling by the T-bar 6. In this case, the side end of the lighting fixture 1A extending in the front-rear direction is placed on the support piece 63 of the long T-bar 6 arranged to extend in the front-rear direction.

[0034] (Installation of end components) In the lighting fixture 1A of this embodiment, a fixture body 2 is formed by attaching a pair of end members 3 to the front and rear ends of a main body 200. The end members 3 are detachably attached to the main body 200 in a state in which the light source unit 1 is removed from the storage section 20.

[0035] 6 and 8, the end member 3 is placed so that the protruding piece 30 overlaps the upper surface of the upper wall portion 210 of the storage section 20. The rising portion 302 is located between a pair of side wall portions 211 of the storage section 20, and the narrow portion 304 is disposed at the position of the notch 26. The main portion 301 is located below the reflector 24.

[0036] A pair of insertion pieces 32 provided on the protruding piece 30 are inserted from above into a pair of slits 25 provided in the upper wall portion 210 of the wall portion 21. Furthermore, the fixing portion 305 provided on the protruding piece 30 is located above the hole portion 22 provided in the upper wall portion 210. Then, a fixing tool 31 such as a screw is inserted into the hole portion 22 from below the upper wall portion 210, and the tip portion of the fixing tool 31 protruding above the hole portion 22 is inserted into the fixing part 305 and coupled. As a result, the fixing tool 31 is inserted into the fixing part 305 provided on the protruding piece 30 and the hole portion 22 provided in the wall portion 21, and the end member 3 is attached to the main body portion 200.

[0037] The end member 3 can slide within the range of the dimension of the hole 22 in the front-rear direction. Figs. 6 and 7 show a state in which the end member 3 is slid to the outermost position (the position farthest from the center of the main body 200 in the front-rear direction). In this case, the fixing portion 305 is located at the outer end of the hole 22 (the end opposite the center of the main body 200 in the front-rear direction). The pair of insertion pieces 32 are also located at the outer ends of the pair of slits 25. Furthermore, the narrow portion 304 is located at the outer end of the cutout portion 26. The cover portion 303 is also located outside the end (front end or rear end) of the main body 200.

[0038] 8 and 9 show a state in which the end member 3 is slid to the innermost position (the position closest to the center of the main body 200 in the front-rear direction). In this case, the fixing portion 305 is located at the inner end of the hole 22 (the end on the center side of the main body 200 in the front-rear direction). The pair of insertion pieces 32 are also located at the inner ends of the pair of slits 25. Furthermore, the narrow portion 304 is located at the inner end of the cutout portion 26. The cover portion 303 is also located inside (below the reflector 24) the end (front end or rear end) of the main body 200.

[0039] In this manner, the end member 3 is formed to be slidable relative to the main body 200 along the front-rear direction. As a result, by sliding at least one of the pair of end members 3 in the front-rear direction relative to the main body 200, it is possible to easily adjust the length from one end member 3 to the other end member 3 (i.e., the entire length of the fixture main body 2 in the front-rear direction). And, for example, even if a gap occurs between the support piece 63 of the T-bar 6 located in the front or rear of the lighting fixture 1A and the front end or rear end of the main body 200, the end member 3 can be slid in the front-rear direction to close the gap with the cover portion 303.

[0040] Furthermore, since the lighting fixture 1A has the insertion piece 32, by inserting the insertion piece 32 into the slit 25, the end member 3 can be slid in the front-rear direction while the insertion piece 32 is guided by the slit 25. Therefore, when the end member 3 slides, it is difficult for it to rotate about an axis in the up-down direction, and the sliding movement can be performed smoothly.

[0041] Furthermore, the lighting fixture 1A has a sliding portion 33 at a portion where the main body 200 and the end member 3 come into contact with each other. This improves the sliding property of the end member 3 relative to the main body 200, and allows the end member 3 to slide smoothly. The sliding portion 33 can be provided, for example, at the left and right ends of the protruding piece 30 extending in the front-rear direction. In this case, the sliding property between the protruding piece 30 and the upper surface of the storage section 20 is improved. The sliding portion 33 can be provided at the upper end of the main portion 301. In this case, the sliding property between the main portion 301 and the lower surface of the reflector 24 is improved. The sliding portion 33 can be formed by providing packing at the left and right ends of the protruding piece 30 or the upper end of the main portion 301, or by curling the left and right ends of the protruding piece 30 or the upper end of the main portion 301.

[0042] (Modification) The embodiment is merely one of various embodiments of the present disclosure. Various modifications of the first embodiment are possible depending on the design and the like as long as the object of the present disclosure can be achieved.

[0043] In the above embodiment, a pair of end members 3 are formed to be freely slidable in the front-to-rear direction, but this is not limited thereto, and only one of the end members 3 provided on the front or rear side may be formed to be freely slidable.

[0044] In the above embodiment, a case has been described in which the hole 22 is formed in the wall 21 and the protruding piece 30 has the fixing portion 305, but this is not limiting, and the wall 21 may have the fixing portion 305 and the hole 22 may be formed in the protruding piece 30. That is, one of the wall 21 and the protruding piece 30 may have the hole 22 into which the fixing device 31 is inserted, and the other of the wall 21 and the protruding piece 30 may have the fixing portion 305 to which the fixing device 31 is coupled.

[0045] In the above embodiment, the hole 22 is formed as a long hole extending in one direction, but this is not limited thereto. For example, as shown in FIG. 11, a plurality of holes 22 may be provided lined up along one direction. In this case, the plurality of holes 22 may be formed lined up in the front-rear direction of the main body 200. Then, a hole 22 at an appropriate position is selected from the plurality of holes 22, aligned with the fixing portion 305, and fixed with the fixing tool 31, whereby the end member 3 can be attached to the desired position of the main body 200.

[0046] In addition, at least one of the main body 200 and the end member 3 may have a mark that serves as a guide for the sliding position of the end member 3 relative to the main body 200. In this case, the end member 3 can be disposed at a desired position using the mark as a guide. An example of the mark is a scale extending in the front-rear direction. Also, the mark may be a symbol that indicates the mounting position of the end member 3.
