In addition, in FIG. 9, the reflecting plate 12 which fixes the attachment metal fitting 14 is not illustrated.

  As shown in FIG. 5, the reflecting plate 12 is formed from, for example, a single sheet metal. The reflector 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 reflecting plate 12 using screws 14s.

  The holding member 23 includes a grip part 30 and a fixing part 31. The grip part 30 is provided at both ends of the fixed part 31. The gripping unit 30 grips with one end of the support 21 and the cover 22 interposed therebetween. One end of the support 21 is curved.

  The grip portion 30 is, for example, a leaf spring, and suppresses the engagement of the cover 22 from 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. Thus, the holding member 23 is attached to the support body 21 and holds the cover 22 on the support body 21. Further, the holding part 30 is provided with a holding part 30a. The holding portion 30 a is a portion that sandwiches one end of the support 21 and the cover 22.

  The fixing portion 31 is provided with an elastic body 40. The elastic body 40 is, for example, a torsion spring. The elastic body 40 is two connected torsion springs. The mounting bracket 14 is attached to the holding member 23 by a part of the elastic body 40 (the contact portion 40f) being hooked on a part of the mounting bracket 14 (the latching portion 14a). Thereby, the light source module 20 is attached to the instrument main body 10.

  As shown in FIG. 6A, the mounting bracket 14 has a latching portion 14a and a protruding portion 14b. For example, the mounting bracket 14 is provided on both sides of the first plate 14P1 having a substantially rectangular shape that contacts the reflection plate 12, the second plate 14P2 having a substantially convex shape provided on the first plate 14P1, and 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.

  Further, an insertion hole 14o is provided in the center of the second plate 14P2 of the mounting bracket 14. For example, the shape of the insertion hole 14o is a substantially rectangular shape.

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

  The protrusions 14b are provided at both ends of the latching portion 14a on the outer edge of the second plate 14P2. 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 that mounts and fixes the wiring in the housing 11 of the instrument body 10.

  As shown in FIG. 6B, the mounting bracket 14 is fixed to the reflector 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 screwing portion 14h are provided. The number of screws 14s and screwing portions 14h may be arbitrary. The number of screws 14s and screwing portions 14h may be one each, or three or more.

  The screwing 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 on the elastic body 40 (main body portion 40c) side from 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. As described above, by providing the mounting bracket 14 with the screwing portion 14h, 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, the elastic body 40 is in a temporarily suspended state in which the elastic body 40 is hooked on the mounting bracket 14, as shown in FIG. That is, when removing the light source module 20 from the instrument main 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 the direction d2 (the mounting direction of the lighting fixture 100). Further, when a force is applied to the light source module 20 in the direction d1, an upward force is applied to the first plate 14P1 of the mounting bracket 14, and a downward force is applied to the second plate 14P2 of the mounting bracket 14.

  When the screw 14s is fixed to the screwing portion 14h provided on the second plate 14P2 side from the center 14c of the first plate 14P1, the screw 14s is provided to the screwing portion 14h provided near the center 14c of the first plate 14P1. Compared with the case where is fixed, when the force of the direction d1 is added to the light source module 20, a deformation | transformation of the attachment metal fitting 14 can be suppressed. Further, when the screw 14s is fixed to the screwing portion 14h in this way, the distance between the screwing portion 14h and the second plate 14P2 is narrowed, and on the opposite side of the second plate 14P2 from the screwing portion 14h, the first plate 14P1. And the contact surface between the reflector 12 and the reflector 12 increase. Thereby, when the force of the direction d1 is added to the light source module 20, a deformation | transformation of the attachment metal fitting 14 can be suppressed.

As shown in FIGS. 8A and 8B, the elastic body 40 includes end portions 40a and 40b, a main body portion 40c, connection portions 40d and 40e, and a contact portion 40f.
The end portions 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 in the fixed portion 31 is inserted through the main body portion 40c. For example, the main body portion 40c is formed of two annular bodies, and the bent portion 31c is inserted through the opening of the annular body. Thereby, the elastic body 40 can be attached to the fixed portion 31.

  The connecting portions 40d and 40e connect the end portions 40a and 40b and the main body portion 40c. The connecting portions 40d and 40e have bent portions. For example, the connecting portions 40d and 40e have a dogleg shape. As a result, the connecting portions 40d and 40e are prevented from coming into contact with the fixing portion 31 of the holding member 23, and the connecting portions 40d and 40e are easily grasped when the elastic body 40 is attached to the fixing portion 31. Therefore, workability when the elastic body 40 is attached to the fixed portion 31 is improved.

  The contact portion 40f is formed by a first portion 40f1, a second portion 40f2, a third portion 40f3, and a fourth portion 40f4. When the elastic body 40 is two torsion springs, the first part 40f1 is a part that 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 hole 14o of the mounting bracket 14, the second portion 40f2 is latched to the latching portion 14a of the mounting bracket 14 by the bent portion. To be fixed. Thereby, the light source module 20 is temporarily suspended from the instrument body 10.

  Since the second portion 40f2 has a bent portion, it is possible to reduce the process of processing the mounting bracket 14 in order to hook the elastic body 40 to the mounting bracket 14. For example, the process of bending a part of the mounting bracket 14 can be reduced. Thereby, processing time can be shortened. Further, the manufacturing cost 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. With such a third portion 40f3, when a predetermined force is applied to the elastic force from the temporarily suspended state, 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 portion 40c. The mounting bracket 14 is attached to the holding member 23 by the fourth portion 40f4 being hooked on the hooking portion 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 40l. Further, 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 is hooked so as to intersect with the latching portion 14a substantially perpendicularly. When such a straight portion 40l is provided in the fourth portion 40f4, an elastic force is applied to the hooking 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. Suction more reliably. That is, since the elastic force in the substantially vertical direction applied to the latching portion 14a increases, the force that the light source module 20 sucks up toward the instrument body 10 increases. Thereby, the light source module 20 can be reliably attached to the instrument main body 10.

Fig.11 (a)-FIG.11 (c) are figures explaining attachment of a light source module and an instrument main body.
In addition, in FIG. 11 (a)-FIG.11 (c), the reflecting plate 12 which fixes the attachment metal fitting 14 is not shown in figure.

  As shown in FIG. 11A, after the first portion 40f1 and the second portion 40f2 are inserted into the insertion hole 14o of the mounting bracket 14, the second portion 40f2 is latched by the latching portion 14a of the mounting bracket 14. Fixed. The light source module 20 is temporarily suspended from the instrument body 10. In the temporarily suspended state, wiring work or the like in the instrument body 10 is performed. The light source module 20 is pushed up by applying an upward force (in the direction of the arrow) from the temporarily suspended state.

  As shown in FIG. 11B, when the light source module 20 is pushed upward by applying a force in the upward direction (arrow direction) 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 hooking 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 is hooked so as to intersect with the hooking portion 14a substantially perpendicularly. When the light source module 20 is sucked toward the instrument body 10, the light source module 20 is attached to the instrument body 10 and fixed.

  In the lighting fixture 100 according to the present embodiment, the light source module 20 is provided with the elastic body 40 and the contact 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 the main body of the fixture. 10 is attached. Thereby, workability | operativity at the time of attaching the light source module 20 to the instrument main body 10 is improved.

  According to this embodiment, the lighting fixture which improved workability is provided.
