  However, in the conventional lighting fixture as described above, the lighting fixture 100 is fixed by sandwiching the ceiling member between the mounting spring 104 and the flange portion 102. There was a problem that the inner peripheral surface of the hole might be damaged.

  The present invention has been made to solve the conventional problems, and an object thereof is to provide a lighting fixture that can be mounted without damaging the inner peripheral surface of the mounting hole.

  The lighting fixture of the present invention includes a light source, a fixture main body that accommodates the light source and is attached to the attachment hole of the attachment portion, and a magnet portion that is attached to a peripheral edge of the attachment hole, and the attachment portion. It has a magnetic body disposed at a position facing the magnet part with a sandwich, and a protrusion provided on the magnet part and fitted into the mounting hole.

  Moreover, the lighting fixture of this invention is divided | segmented into plurality along the radial direction of the said attachment hole, and the said magnet part comprises the continuous ring in a mounting state.

  Furthermore, the lighting fixture of this invention WHEREIN: The said magnet part is arrange | positioned inside the said to-be-attached part, and the said magnetic body is attached to the collar part provided in the lower end part of the said instrument main body.

  Since this invention attaches the fixture main body of a lighting fixture to the attachment hole of a to-be-attached part via a magnet part and a magnetic body, it has the effect that it can attach without damaging the internal peripheral surface of an attachment hole. Can be provided.

It is sectional drawing which shows the state inserted in A, (C) is sectional drawing and the top view which show the state in which the attachment metal fitting was attached to the attachment hole, (D) shows the state which attached the lighting fixture to the attachment hole. Cross section Sectional drawing which shows the state which removes a lighting fixture Sectional view of a conventional recessed luminaire

Hereinafter, the lighting fixture of embodiment which concerns on this invention is demonstrated using drawing.
As shown in FIG. 1, the lighting fixture 10 of embodiment which concerns on this invention can employ | adopt the downlight attached to the attachment hole 12 provided in the ceiling 11 which is a to-be-attached part, and mainly illuminates below. .

The lighting fixture 10 includes a box-shaped fixture main body 20 that houses a light source (not shown) therein, and a frame body 21 at a lower portion of the fixture main body 20. At the lower end of the frame body 21, a circular ring-shaped flange portion 22 is provided, and the flange portion 22 is exposed from the ceiling 11. On the outer surface of the frame body 21, a plurality of attachment springs 23 are provided at predetermined intervals in the circumferential direction so as to protrude outward in order to attach the instrument body 20 to the ceiling 11.
A magnetic body 33 such as iron is attached to the flange portion 22. Magnetic bodies 33 having a predetermined size can be arranged at predetermined intervals. Moreover, the ring-shaped magnetic body 33 can also be used by integral molding. Or the collar part 22 can also be formed with a magnetic body.

As shown in FIGS. 1 and 2B, the mounting bracket 30 is attached along the inner peripheral edge of the mounting hole 12 in the upper surface 111 of the ceiling 11.
As shown in FIGS. 2A and 2B, the mounting bracket 30 is formed from a magnet portion 31 and a protruding portion 32 and has an L-shaped cross section. The magnet portion 31 is an annular plate member, and a magnet 311 is attached to the lower surface.

The protrusion 32 is in contact with the inner peripheral surface 121 of the mounting hole 12, and the magnet 311 is in contact with the upper surface (periphery) 111 of the ceiling 11 in the magnet portion 31. That is, the protrusion 32 is a cylindrical member having an outer diameter that is approximately equal to the inner diameter of the mounting hole 12, and has an internal space 34 (see FIG. 3C) on the inner side.
Further, the height of the protrusion 32 is set so that the lower end surface 321 does not protrude downward from the lower surface 112 of the ceiling 11.

Therefore, as shown in FIG. 2B, the magnet 311 of the magnet unit 31 faces the magnetic body 33 of the flange unit 22 with the ceiling 11 interposed therebetween.
Note that the mounting bracket 30 is divided into a plurality (for example, divided into four) along the radial direction (divided mounting bracket 30A). When combined, the magnet portion 31 has an annular shape, and the protrusion 32 has a cylindrical shape. Thus, the internal space 34 is formed. As illustrated in FIG. 3C, the lighting fixture 10 is attached to the internal space 34.

Next, a procedure for attaching the lighting fixture 10 to the attachment hole 12 will be described.
First, the attachment fitting 30 is attached to the attachment hole 12. As shown in FIG. 3A, the outer end 312 of the magnet portion 31 of the split mounting bracket 30 </ b> A is inserted from below the mounting hole 12.
Next, as shown in FIG. 3B, the second and subsequent divided mounting brackets 30A are inserted from below the mounting holes 12 in the same manner.
As shown in FIG. 3C, when all the divided mounting brackets 30 </ b> A are inserted into the mounting holes 12 and then arranged along the inner peripheral surface 121 of the mounting holes 12, the magnet portion 31 becomes a disc shape, and the protrusions 32 becomes a cylindrical shape.

Finally, as shown in FIG. 3 (D), the luminaire 10 is attached to the internal space 34 of the protrusion 32 by a process similar to the conventional one. Thereby, the lighting fixture 10 is attached to the internal space 34 of the attachment metal fitting 30 by cooperation of the attachment spring 23 and the collar part 22, for example.
In addition, when removing the lighting fixture 10 from the ceiling 11, as shown in FIG. 4, the collar part 22 can be pulled down and can be removed similarly to the past.

As mentioned above, according to the lighting fixture 10 of embodiment which concerns on this invention demonstrated, the magnet part 31 is attached to the periphery of the attachment hole 12 provided in the ceiling 11, and it is magnetic in the position which opposes the magnet part 31 on both sides of the ceiling 11. The body 33 is attached.
At this time, since the projection 32 provided on the magnet portion 31 fits into the attachment hole 12, the magnet portion 31 can be easily attached to the attachment hole 12.
Thereby, since the fixture main body 20 of the lighting fixture 10 is attached to the mounting hole 12 of the ceiling 11 via the magnet part 31 and the magnetic body 33, the lighting fixture 10 is attached without damaging the inner peripheral surface 121 of the mounting hole 12. Can do.

Moreover, since the magnet part 31 is divided | segmented into multiple along the radial direction of the attachment hole 12, the magnet part 31 can be inserted in the attachment hole 12 easily.
Moreover, since the magnet part 31 comprises the continuous ring in the mounting | wearing state, after inserting the magnet part 31 in the attachment hole 12, the magnet part 31 can be attached over the perimeter of the attachment hole 12, and an attachment hole Twelve peripheral edges (upper surface 111) can be protected over the entire periphery.

Furthermore, since the magnet part 31 is arrange | positioned inside the ceiling 11, and the magnetic body 33 is arrange | positioned at the collar part 22 provided in the lower end part of the instrument main body 20 on both sides of the ceiling 11, the magnet part 31 and the magnetic body 33 are They are attracted to each other by magnetic force.
Thereby, the magnet part 31 and the magnetic body 33 can be attached across the ceiling 11.

In addition, the lighting fixture 10 of this invention is not limited to embodiment mentioned above, A suitable deformation | transformation, improvement, etc. are possible.
For example, in the above-described embodiment, the case where the lighting fixture 10 is mounted by sandwiching the ceiling 11 between the mounting spring 23 and the flange portion 22 has been described. In addition, when the attracting force between the magnet 311 and the magnetic body 33 of the mounting bracket 30 is sufficiently large, for example, without providing another member such as the mounting spring 23, the attracting force between the magnet 311 and the magnetic body 33 is used. It is also possible to attach the lighting fixture 10 to the ceiling 11.
