Description

  The present invention relates to a structure for attaching a reflector to an inner surface of a lighting shade.

  In a high ceiling lighting fixture or the like, it has been conventionally performed to provide a reflective material on the inner surface of the lighting shade.

JP 2005-346968 A

  However, it is necessary to design a single item for the reflector to be installed on the inner surface of the shade of the existing lighting fixture, because the mounting shape of the shade and the bulb holder is different for each lighting fixture. There is a problem of high costs.

  In view of the above-described problems, the present invention provides a structure for attaching a reflector to an inner surface of an illumination shade that can be advantageously attached to the inner surface of the illumination shade. Is an issue.

  The above-mentioned problem is that at least three places spaced in the circumferential direction of the lower end peripheral wall portion of the reflector are attached to the lower end peripheral wall portion of the illumination shade by the fixture, so that the reflector is the inner surface portion of the illumination shade. This is solved by the structure for attaching the reflective material to the inner surface of the lighting shade (first invention).

  With this structure, it is possible to attach reflectors using the same fixture between many lighting fixtures that have commonality in the shape and size of the lower end peripheral wall of the lighting shade, and increase the versatility of the installation. The reflective material can be attached without depending on the mounting shape of the shade and the bulb holder, and the reflective material can be attached to the inner surface of the illumination shade in an advantageous manner.

  In the first invention, the fixture may be attached to the lower peripheral wall portion of the illumination shade by sandwiching the lower end circumferential wall portion of the illumination shade from the inside and outside directions (second invention). In this case, the fixture, and hence the reflector, can be securely attached to the lighting shade without any backlash.

In the first invention, each of the fixtures is
One end side is attached to the lower peripheral wall portion of the reflector, and the other end wraps under the lower peripheral wall portion of the lighting shade, and is spaced from the outer peripheral side of the lower end peripheral wall portion of the illumination shade to the lower end outer peripheral portion. And the base material to be placed
A male thread material screwed inwardly to the other end of the base material;
By providing an elastic material interposed between the lower peripheral wall portion of the reflector and the lower peripheral wall portion of the lighting shade, and by screwing the male thread material of each fixture inward The reflective material may be held on the inner surface of the lighting shade by the male screw material and the elastic material sandwiching the lower end peripheral wall portion of the lighting shade from the inside and outside directions (third invention). .

  In this case, not only can the fixture and the reflecting material be securely attached to the lighting shade, but also there is a slight difference in the shape and size of the lower peripheral wall of the lighting shade. Even if it exists, the elastic material absorbs the difference by the elasticity, and versatility can be improved, and attachment of the reflective material to the shade shade inner surface portion can be performed more advantageously in terms of cost.

  Since the reflection member mounting structure to the lighting shade inner surface portion of the present invention is as described above, the reflection material can be attached to the lighting shade inner surface portion in an advantageous manner in terms of cost.

The attachment structure of embodiment is shown, The figure (A) is the whole front view which shows the attachment state of a lighting fixture, A figure (B) is the bottom view, A figure (C) is an expanded sectional view of a reflector attachment part. .

  Next, embodiments of the present invention will be described with reference to the drawings.

  In the structure of the embodiment shown in FIG. 1, 1 is a light bulb holder, 2 is a lighting shade, 3 is a light bulb, 4 is a reflector, and 8 is a fixture.

  As shown in FIG. 1 (b), the reflecting material 4 has an inner reflecting surface that is polygonal in the circumferential direction, and is opened at three or more steps at different angles from the proximal side to the distal side. The base end portion is provided with a through hole through which the base end screwed portion 3a can be passed.

  As shown in FIG. 1 (b), at least three places spaced in the circumferential direction of the lower end peripheral wall 4b of the reflector 4 are illuminated by the fixtures 8 as shown in FIG. 1 (c). The reflector 4 is held on the inner surface of the illumination shade 2 by being attached to the lower peripheral wall portion 2a of the shade 2.

The fixture 8 is
One end side is attached to the lower peripheral wall portion 4b of the reflector 4 with rivets, bolts 9 and an adhesive, and the other end wraps under the lower peripheral wall portion 2a of the lighting shade 2 and the lower end of the illumination shade 2 On the outer peripheral side of the peripheral wall portion 2a, a base material 10 arranged with a space between the lower end outer peripheral portion,
A male screw material 11 screwed inwardly to the other end side of the base material 10;
-It comprises an elastic material 12 made of rubber or a spring interposed between the lower end peripheral wall portion 4b of the reflector 4 and the lower end peripheral wall portion 2a of the lighting shade 2, and is provided at three locations in the circumferential direction. By screwing the male screw material 11 of each fixture 8 provided in the inward direction, the male screw material 11 and the elastic material 12 sandwich the lower end peripheral wall portion 2a of the lighting shade 2 from the inner and outer directions. So that the reflector 4 is held on the inner surface of the lighting shade 2.

  In this structure, the reflector 4 can be mounted using the same mounting tool 8 among many lighting fixtures having commonality in the shape and size of the lower peripheral wall portion of the lighting shade 2 and versatility of mounting. The reflective member 4 can be attached without depending on the mounting shape of the shade 2 and the bulb holder 1, and the reflective member 4 can be attached to the inner surface of the lighting shade 2 in terms of cost. It can be carried out.

  Moreover, since the fixture 8 is structured to be attached to the lower peripheral wall portion 2a of the illumination shade 2 by sandwiching the lower end circumferential wall portion 2a of the illumination shade 2 from the inside and outside directions, the fixture 8 and therefore the reflection. The material 4 can be securely attached to the lighting shade 2 without rattling.

  Further, by adopting the elastic material 12, even if there is a slight difference in the shape and size of the lower peripheral wall portion of the lighting shade 2, the difference is absorbed and the versatility is enhanced. The reflection material 4 can be attached to the inner surface portion more advantageously in terms of cost.
