  The substrate 25 is provided between the support 21 and the cover 22. The substrate 25 is fixed by being sandwiched between the first surface 21 a of the support 21 and the placement portion 22 a of the cover 22. More desirably, the substrate 25 is sandwiched between the first surface 21 a of the support 21 and the mounting portion 22 a of the cover 22. The mounting portion 22a is a part of the cover 22 that comes into contact with a part of the first surface 25a of the substrate 25 and extends toward the inside of the light source module 20 (for example, a portion where the light source 26 is provided). Part. Moreover, the mounting part 22a is provided in a rectangular shape along the longitudinal direction of the substrate 25, for example. The placement portion 22a is not limited to being formed continuously in the longitudinal direction of the substrate 25, and may be partially formed at several locations in the longitudinal direction.

  The mounting portion 22 a is formed by providing a step in the cover 22 toward the inside of the light source module 20. Specifically, the placement portion 22 a is formed in a step shape so as to bend toward the space S inside the cover 22. The mounting portion 22a accommodates at least a part of the substrate 25 in the step portion. For example, the mounting portion 22 a is accommodated so as to face the side surface of the substrate 25. In this case, the side surface of the substrate 25 is a surface provided between the first surface 25 a and the second surface 25 b of the substrate 25. When a part of the first surface 25a of the substrate 25 is placed on the placement portion 22a by the placement portion 22a, the substrate 25 is in the lateral direction (for example, perpendicular to the direction from the support 21 toward the cover 22). Movement). As a result, the substrate 25 is stably fixed between the support 21 and the cover 22.

  As shown in FIG. 6, a part of the first surface 25 a of the substrate 25 is placed on the placement portion 22 a so as to accommodate the substrate 25 as indicated by the arrow, and the first surface 21 a of the support 21 The second surface 25b of the substrate 25 is brought into contact. As a result, the substrate 25 is sandwiched between the support 21 and the cover 22, and the curved portion 21 c of the support 21 is fixed to the bent portion 22 b of the cover 22, so that the substrate 25 is fixed between the support 21 and the cover 22. .

  The mounting portion 22 a as shown in FIGS. 5 and 6 is provided so as to be fixed to the substrate 25. The placement portion 22a may be provided so as to be movable in a predetermined direction with respect to the substrate 25.

  For example, as illustrated in FIG. 7, the substrate 25 is provided between the support 21 and the cover 22. The cover 22 has a placement portion 22a1. The substrate 25 is fixed by being sandwiched between the first surface 21 a of the support 21 and the placement portion 22 a 1 of the cover 22. The mounting portion 22a1 is a part of the cover 22 that comes into contact with a part of the first surface 25a of the substrate 25 and extends toward the inside of the light source module 20 (for example, a portion where the light source 26 is provided). Part. Further, the placement portion 22a1 is provided in a rectangular shape along the longitudinal direction of the substrate 25, for example. The placement portions 22a1 may be partially formed at several locations in the longitudinal direction of the substrate 25.

  The mounting portion 22a1 is formed by providing a step on the cover 22 toward the inside of the light source module 20. Specifically, the placement portion 22 a 1 is formed in a stepped shape so as to bend toward the space S inside the cover 22. The mounting portion 22a1 accommodates the substrate 25 in the step portion. For example, the mounting portion 22 a 1 is accommodated so as to face the side surface of the substrate 25. When a part of the first surface 25a of the substrate 25 is placed on the placement portion 22a1 by the placement portion 22a1, the substrate 25 is in the lateral direction (for example, perpendicular to the direction from the support 21 toward the cover 22). Movement). As a result, the substrate 25 is stably fixed between the support 21 and the cover 22.

  As shown in FIG. 8, the placement portion 22 a 1 is provided to be inclined downward toward the space S inside the cover 22. The cover 22 has bent portions 22b in the vicinity of both ends of the cover 22 so as to have an opening 22o. The support 21 has curved portions 21c at both ends so as to have an opening 21o. A width W1 between the bent portions 22b of the cover 22 is smaller than a width W2 between the curved portions 21c of the support body 21. That is, the opening 22o is smaller than the opening 21o.

  A part of the first surface 25a of the substrate 25 is placed on the placement portion 22a1 so as to accommodate the substrate 25, and the first surface 21a of the support 21 and the placement portion as shown by the arrow in FIG. A force is applied downward so as to sandwich the substrate 25 by 22a1. When a downward force is applied, the bent portion 22b and the curved portion 21c come into contact with each other as shown in FIG. 7, and the bent portion 22b moves outward and is fixed. Since the width W1 between the bent portions 22b of the cover 22 is smaller than the width W2 between the bent portions 21c of the support body 21, the force that the bent portions 21c push the bent portions 22b outward adds to the bent portions 22b. Moves outward and is fixed. The curved portion 21c is attached to the cover 22 so as to widen the width W1 between the bent portions 22b.

  Further, when the bent portion 22b and the curved portion 21c come into contact with each other and the bent portion 22b moves to the outside, the mounting portion 22a1 connected to the bent portion 22b faces upward with respect to the substrate 25 as shown in FIG. 25 in a direction from 25 toward the support body 21). That is, the mounting portion 22a1 contacts the substrate 25 by a force toward the support body 21, and presses and fixes the substrate 25. When the substrate 25 is sandwiched between the support body 21 and the cover 22 and fixed between the support body 21 and the cover 22, the mounting portion 22 a 1 inclined downward is substantially parallel to the substrate 25. Become. As described above, when the substrate 25 is provided between the support body 21 and the cover 22, the hanging of the mounting portion 22 a 1 due to variations in the processing of the cover 22 is canceled by spreading the cover 22 when the support body 21 is attached. be able to.

  In the luminaire 100 of the present embodiment, the cover 22 is provided with a mounting portion 22a that sandwiches the substrate 25 with the support 21. Providing such a mounting portion 22 a makes it possible to stably fix the substrate 25 between the support 21 and the cover 22. Moreover, since the board | substrate 25 can be fixed between the support body 21 and the cover 22 without attaching the board | substrate 25 to the support body 21, the process of attaching the board | substrate 25 to the support body 21 using a latching claw etc. There is no need to provide it. Thereby, the manufacturing process of the lighting fixture 100 can be reduced, and the assembly property of the lighting fixture 100 can be improved.

  Further, in the case where the mounting portion 22a1 that is movable in a predetermined direction with respect to the substrate 25 is provided, it is possible to suppress the sagging of the mounting portion 22a1 and to stably fix the substrate 25 between the support body 21 and the cover 22. it can.

  7 and 8 are extreme examples. For example, the width W1 between the bent portions 22b is smaller than the width W2 between the curved portions 21c, and the bent portions are fixed when the support 21 and the cover 22 are fixed. The width of the curved portion 21c is widened by 22b, and as a result, a force toward the support body 21 is generated in the mounting portion 22a1, so that the shape of the support body 21 can be used as long as the substrate 25 can be pressed and fixed. And the shape of the cover 22 can have arbitrary shapes. That is, even if it is the shape of the normal support body 21 and the shape of the cover 22 like FIG.5 and FIG.6, the force of a predetermined direction arises in the mounting part 22a by attaching the cover 22 to the support body 21. Such a structure and dimensions may be used.
