FIG. 9 is a perspective view showing a state in which the elastic body 40 is hooked on the mounting bracket 14. FIG. 10 is a side view showing a state in which the elastic body 40 is hooked on the mounting bracket 14. In FIG. 9, the reflection plate 12 for fixing the mounting bracket 14 is not shown.

  As shown in FIG. 5, the reflection plate 12 is formed from, for example, one sheet metal. The reflection plate 12 has a plurality of bent portions 12f. The concave portion 11a is formed by a part of the plurality of bent portions 12f. For example, the mounting bracket 14 is fixed to the reflection plate 12 using screws 14s.

  The holding member 23 has a grip part 30 and a fixing part 31. The holding parts 30 are provided at both ends of the fixing part 31. The grip 30 grips one end of the support 21 and the cover 22. One end of the support 21 is curved.

  The grip portion 30 has, for example, a leaf spring shape, and suppresses the engagement of the cover 22 being released by sandwiching the support 21 and the cover 22. The holding member 23 suppresses the opening of the cover 22 by being sandwiched between the grip portions 30. As described above, the holding member 23 is attached to the support 21, and holds the cover 22 on the support 21. Further, the holding unit 30 is provided with a holding unit 30a. The holding portion 30 a is a portion that sandwiches one end of the support 21 and the cover 22.

  An elastic body 40 is provided on the fixing portion 31. The elastic body 40 is, for example, a torsion spring. The elastic body 40 is two connected torsion springs. A part of the elastic body 40 (the contact part 40f) is hooked on a part (the hook part 14a) of the fitting 14 so that the fitting 14 is attached to the holding member 23. Thereby, the light source module 20 is attached to the fixture main body 10.

  As shown in FIG. 6A, the mounting bracket 14 has a hook portion 14a and a protruding portion 14b. For example, the mounting bracket 14 has a substantially rectangular first plate 14P1 in contact with the reflection plate 12, a substantially convex second plate 14P2 provided on the first plate 14P1, and two opposing sides of the second plate 14P2. It is formed by combining the third plate 14P3 provided. The second plate 14P2 is provided at a predetermined angle with respect to the first plate 14P1, and the third plate 14P3 is provided at a predetermined angle with respect to the second plate 14P2. For example, the second plate 14P2 is provided substantially perpendicular to the first plate 14P1, and the third plate 14P3 is provided substantially perpendicular to the second plate 14P2. The mounting bracket 14 is not limited to being formed by combining a plurality of plates, and may be formed from a single plate.

  An insertion hole 14o is provided at the center of the second plate 14P2 of the mounting bracket 14. For example, the shape of the insertion hole 14o is substantially rectangular.

  The engaging portion 14a is a part of the second plate 14P2, which is for engaging the elastic body 40. For example, the hook 14a has a substantially rectangular shape. In the mounting bracket 14, a hook 14a and an insertion hole 14o are integrally provided on the second plate 14P2.

  The protruding portions 14b are provided on the outer edges of the second plate 14P2 and at both ends of the hooking portions 14a. The tip 14p of the protrusion 14b is bent so as to be substantially parallel to the third plate 14P3. For example, the protruding portion 14b is a portion on which the wiring and the like in the housing 11 of the instrument body 10 are placed and fixed.

  As shown in FIG. 6B, the mounting bracket 14 is fixed to the reflection plate 12 using a screwing portion 14h for fixing the screw 14s. For example, the screwing portion 14h is a screw hole. In this example, two screws 14s and a screw fixing portion 14h are provided, respectively. The numbers of the screws 14s and the screwing portions 14h may be arbitrary. The number of the screws 14s and the number of the screwing portions 14h may be one or three or more.

  The screw portion 14h is provided on the second plate 14P2 side from the center 14c of the first plate 14P1. For example, the screwing portion 14h is provided closer to the elastic body 40 (main body portion 40c) than the center 14c of the first plate 14P1. The center 14c of the first plate 14P1 is an intersection of two diagonal lines when the shape of the first plate 14P1 is rectangular. By thus providing the screwing portion 14h on the mounting bracket 14, the deformation of the mounting bracket 14 can be suppressed.

  For example, as shown in FIG. 7A, a force is applied to the light source module 20 in a direction d1 (a direction opposite to the mounting direction of the lighting fixture 100) from a state in which the elastic body 40 is hooked and fixed to the mounting bracket 14. Add. When a predetermined downward force is applied to the elastic force of the elastic body 40, a temporary suspension state in which the elastic body 40 is hung on the mounting bracket 14 is obtained as shown in FIG. 7B. That is, when the light source module 20 is detached from the appliance body 10, a force is applied to the light source module 20 in the direction d1.

  When a force is applied to the light source module 20 in the direction d1, a force is applied to the fixture body 10 in a direction d2 (the mounting direction of the lighting fixture 100). When a force is applied to the light source module 20 in the direction d1, a force is applied upward to the first plate 14P1 of the mounting bracket 14, and a force is applied downward to the second plate 14P2 of the mounting bracket 14.

  When the screw 14s is fixed to the screw portion 14h provided on the second plate 14P2 side from the center 14c of the first plate 14P1, the screw 14s is fixed to the screw portion 14h provided near the center 14c of the first plate 14P1. When the force in the direction d1 is applied to the light source module 20, the deformation of the mounting bracket 14 can be suppressed, as compared with the case where is fixed. When the screw 14s is fixed to the screwed portion 14h in this way, the distance between the screwed portion 14h and the second plate 14P2 is reduced, and the first plate 14P1 is located on the opposite side of the second plate 14P2 from the screwed portion 14h. The contact surface between the electrode and the reflection plate 12 increases. Thereby, the deformation of the mounting bracket 14 when a force in the direction d1 is applied to the light source module 20 can be suppressed.

As shown in FIGS. 8A and 8B, the elastic body 40 has ends 40a and 40b, a main body 40c, connecting parts 40d and 40e, and a contact part 40f.
The ends 40a and 40b are inserted through openings 31a and 31b provided in the fixing portion 31 of the holding member 23, respectively. Further, the bent portion 31c provided on the fixing portion 31 is inserted through the main body portion 40c. For example, the main body 40c is formed of two annular bodies, and the bent part 31c is inserted through the opening of the annular body. Thereby, the elastic body 40 can be attached to the fixing portion 31.

  The connecting portions 40d, 40e connect the ends 40a, 40b and the main body 40c. The connecting portions 40d and 40e have bent portions. For example, the connecting portions 40d and 40e have a U shape. This suppresses the connection portions 40 d and 40 e from contacting the fixing portion 31 of the holding member 23, and makes it easier to grasp the connection portions 40 d and 40 e when attaching the elastic body 40 to the fixing portion 31. Therefore, workability when attaching the elastic body 40 to the fixing portion 31 is improved.

  The contact part 40f is formed by the first part 40f1, the second part 40f2, the third part 40f3, and the fourth part 40f4. When the elastic body 40 is composed of two torsion springs, the first portion 40f1 is formed on the distal end side of the elastic body 40 and connects the two torsion springs.

The second portion 40f2 is provided at both ends of the first portion 40f1. At least a part of the second portion 40f2 is bent.
As shown in FIG. 9, after the first portion 40f1 and the second portion 40f2 are inserted into the insertion holes 14o of the mounting bracket 14, the second portion 40f2 is hooked on the hooks 14a of the mounting bracket 14 by the bent portions. It is fixed. As a result, the light source module 20 is temporarily suspended from the appliance body 10.

  Since the second portion 40f2 has a bent portion, it is possible to reduce the number of steps for processing the mounting bracket 14 in order to lock the elastic body 40 on the mounting bracket 14. For example, the number of steps for bending a part of the mounting bracket 14 can be reduced. Thereby, the processing time can be reduced. In addition, manufacturing costs can be reduced.

  The third portion 40f3 is provided at one end of the second portion 40f2. At least a part of the third portion 40f3 is curved. For example, the shape of the third portion 40f3 is an R shape. When a predetermined force is applied to the elastic force from the temporarily suspended state by such a third portion 40f3, the elastic body 40 can be easily inserted into the mounting bracket 14.

  The fourth portion 40f4 is provided between one end of the third portion 40f3 and the main body 40c. The fitting 14 is attached to the holding member 23 by the fourth portion 40f4 being hooked by the hook 14a. That is, the light source module 20 is attached and fixed to the instrument body 10 by the elastic body 40.

  As shown in FIG. 10, at least a part of the fourth portion 40f4 has a straight portion 401. The straight portion 40l is a portion that is inserted in a direction substantially perpendicular to the insertion hole 14o of the mounting bracket 14, and intersects and intersects substantially perpendicularly with the engaging portion 14a. When such a straight portion 40l is provided in the fourth portion 40f4, an elastic force is applied to the engaging portion 14a in the direction d3 (the direction opposite to the mounting direction of the lighting fixture 100), so that the light source module 20 moves toward the fixture main body 10. It sucks up more reliably. That is, since the substantially vertical elastic force applied to the hook portion 14a increases, the force of the light source module 20 sucking up toward the instrument body 10 increases. Thereby, the light source module 20 can be securely attached to the fixture body 10.

FIGS. 11A to 11C are views for explaining the attachment between the light source module and the instrument body.
11A to 11C, the reflection plate 12 for fixing the mounting bracket 14 is not shown.

  As shown in FIG. 11A, after the first portion 40f1 and the second portion 40f2 are inserted into the insertion holes 14o of the mounting bracket 14, the second portion 40f2 is hooked on the hooks 14a of the mounting bracket 14. Fixed. The light source module 20 is temporarily suspended from the instrument body 10. In the state of temporary suspension, wiring work and the like in the instrument body 10 are performed. An upward (arrow direction) force is applied to the light source module 20 from the temporarily suspended state to push it up.

  As shown in FIG. 11B, when the light source module 20 is pushed upward by applying an upward force (arrow direction) to the light source module 20 from the temporarily suspended state, the third portion 40f3 enters the insertion hole 14o. That is, the elastic body 40 is inserted into the mounting bracket 14.

  As shown in FIG. 11C, when an upward force is further applied to the light source module 20 from the state of FIG. 11B to push it up, the fourth portion 40f4 is hooked on the hook portion 14a. That is, the straight portion 40l of the fourth portion 40f4 is inserted in a direction substantially perpendicular to the insertion hole 14o, and intersects and intersects the engaging portion 14a almost perpendicularly. When the light source module 20 is sucked up toward the appliance main body 10, the light source module 20 is attached and fixed to the appliance main body 10.

  In the lighting fixture 100 according to the present embodiment, the light source module 20 is provided with the elastic body 40 and the abutting portion 40f of the elastic body 40 is hooked on the hooking portion 14a of the mounting bracket 14, so that the light source module 20 is in the fixture body. Attached to 10. Thereby, workability when attaching the light source module 20 to the fixture body 10 is improved.

  According to the present embodiment, a lighting fixture having improved workability is provided.
