DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a schematic configuration diagram showing a lighting device according to an embodiment of the present invention, and FIG.
(B) is a sectional view of a main part, and (c) is a bottom view of the main part. This lighting fixture includes a fixture main body 1 and a glove 2 which is attached to the fixture main body 1 by being rotated.

A lighting device (not shown), a lamp (not shown), and the like are attached to the center of a substantially disc-shaped top plate 1a, and a rising portion 7 facing downward is provided at the peripheral edge of the appliance body 1. , Receiving bracket 4 on top plate 1a close to rising portion 7
Is provided.

The receiving fitting 4 has a substantially L-shaped receiving part 4a which is substantially horizontal at the lower end, and a guide part 4b which extends obliquely downward from the lower end of the receiving part 4a along the circumferential direction of the instrument body 1. It is composed of

The globe 2 is made of, for example, glass having translucency, surrounds the lamp 6, and has a flat portion 2a at the upper end.
A rising portion 8 facing upward is provided at a peripheral edge of the opening. Further, the tip of the rising portion 8 is extended outside the opening so that the cross section of the opening peripheral portion becomes substantially U-shaped, and constitutes the extending portion 8a. It is formed in a shape.

In this embodiment, the extension 8
Although a was formed in a step shape, it is not limited to this.

When the opening of the glove 2 is pushed up and rotated in alignment with the apparatus main body 1, the overhanging portion 3 is guided by the guide portion 4b of the receiving bracket 4, rides on the receiving portion 4a, and the overhanging portion 3 is received. It is supported by the part 4 a and is mounted on the instrument body 1.

Here, in the present embodiment, the height A of the rising portion 8 is higher than the height B of the rising portion 7 of the instrument body 1, and when the glove 2 is attached to the instrument body 1, The upper surface of the extending portion 8a comes into contact with the lower flat portion of the main body 1.

The height C between the upper surface of the lower end of the receiving portion 4a and the lower surface of the top plate 1a is equal to the height of the flat portion 2a of the glove 2.
Is set slightly lower than the height A 'between the lower surface of the top plate and the upper surface of the extension portion 8a, and when the overhanging portion 3 enters the receiving portion 4a, the lower side of the top plate 1a. The upper surface of the extension portion 8a is pressed against the flat surface portion of the extension portion 8a.

At the open end of the glove 2, the same number of protrusions 3 as the number of receiving fittings 4 projecting toward the center of the opening are provided. An overhanging portion 3 is provided at a location where the bulging portion 3 is located.

The height D of the rising portion 8 is equal to the height C
Lower than the overhanging portion 3 and the receiving portion 4a
, So that the overhang 3 does not contact the lower surface of the top plate 1a.

Next, FIGS. 2 to 4 are cross-sectional views of essential parts showing different embodiments of the lighting fixture according to the present invention. FIG.
The lighting fixture shown in FIG. 1 has a configuration in which the tip of the rising portion 8 formed in a step shape is inclined upward in the lighting fixture shown in FIG. The upper end of the point that has been pressed can be pressed down.

In FIG. 2, the extending portion 8a is formed in a step shape, but the present invention is not limited to this. Further, the tip of the rising portion 7 is the flat portion 2a of the glove 2.
It may or may not be contacted, but if it does, insect repellency can be further enhanced.

The lighting device shown in FIG. 3 has a configuration in which the tip of the rising portion 7 of the lighting device body 1 is brought into contact with the flat portion 2a of the glove 2 in the lighting device shown in FIG.

The lighting fixture shown in FIG. 4 has a structure in which the extending portion 8a is extended in the opposite direction to the lighting fixture shown in FIG.

In the luminaire shown in FIGS. 2 and 3, the extension 8a may extend in the opposite direction, that is, extend in the direction of the center of the opening of the globe 2.

With the above configuration, in all of the above-described embodiments, the lower surface of the top plate 1a and the extended portion 8a are in contact with each other over a wide area, so that insect repellency is enhanced.

Further, since the tip of the rising portion 7 of the instrument main body 1 and the flat portion 2a of the glove 2 are in contact with each other, as in the conventional example, the contact is made closer to the receiving metal fitting 4, so that Increases insect repellency.

Further, when heat is applied, the glove 2
Even if is deformed, even if the lower part hangs down from the receiving fitting 4, the upper part does not hang down, so that insect repellency can be maintained.

Also, in the lighting fixture shown in FIGS. 1, 2 and 4, since the tip of the rising part 7 of the fixture main body 1 and the flat part 2a of the glove 2 are not in contact, the fitting 4 of the globe 2 Even if the lower part hangs, the appearance is not collapsed because it is not noticeable.

Further, since the extended portion 8a as well as the rising portion 8 is provided at the peripheral edge of the opening of the glove 2, the strength can be increased.

In the lighting fixture shown in FIG.
a is inclined to provide elasticity, so that
The force applied when the projecting portion 3 enters the receiving portion 4a can be reduced, and a large dimensional variation can be obtained.

Further, since the extended portion 8a having the inclination is pressed downward to enter the receiving portion 4a, even if the extended portion 8a starts drooping, the extended portion 8a is directed upward. The contact with the lower surface of the top plate 1a is maintained by the elastic force, so that insect repellency can be maintained.

Further, since the projecting portion 3 is not brought into contact with the lower surface of the top plate 1a, the force applied when the glove 2 is attached to the instrument body 1 can be reduced.

[0038]

According to the first aspect of the present invention, there is provided an extending portion extending substantially in parallel with the top plate from the tip of the second rising portion,
When the glove is attached to the instrument body, the extended part comes into contact with the surface of the instrument body on which the metal fittings are provided. Even if it is deformed, since it does not hang above the receiving bracket, insect repellency can be secured, and by providing the extended portion, strength can be increased, and a lighting device with high insect repellency can be provided. .

According to a second aspect of the present invention, in the lighting fixture of the first aspect, the extending portion is inclined toward the mounting surface side to the fixture main body. By attaching the glove to the instrument body so that the extension part is pushed down, the extension part can have elasticity, the force applied when attaching the glove to the instrument body can be reduced, and the extension part Even if it hangs down, the insect repellency can be ensured by the upward elastic force, and the elasticity allows a large dimensional variation.

According to a third aspect of the present invention, in the lighting device according to the first or second aspect, when the globe is attached to the device main body, the first rising portion abuts on the flat portion, so that the lighting device has two positions. As a result, the instrument body and the glove are provided, and in addition to the effects of the first or second aspect of the invention, insect repellency can be further enhanced.

According to a fourth aspect of the present invention, in the lighting fixture according to any one of the first to third aspects, the extending portion has a stepped shape. In addition to the effect, the force applied when attaching the glove to the instrument body can be reduced.
