Description

[Detailed explanation of the idea] This invention relates to lighting equipment.

Conventionally, a waterproof lighting fixture shown in FIG. 1 has been used.

In the figure, reference numeral 1 denotes a socket into which a light bulb 2 is screwed, and is attached to a mounting surface 4 via a backing 3.

Reference numeral 5 denotes a bottomed cylindrical globe that covers the light bulb 2, and a male threaded portion 6 is provided on the outer periphery of the upper end, and a flange 7 is provided protruding from the terminal end of the male threaded portion 6.

The globe 5 is screwed onto a mounting member 8 that is loosely fitted around the outer periphery of the socket 1.

The mounting member 8 is formed of a metal plate, and includes an inner cylinder part 8a whose inner surface is formed with a female thread, and a cover cylinder part 8b which is folded back and extended outward from the tip of the inner cylinder part 8a. have.

The cover cylindrical portion 8b is provided to prevent the external appearance from being spoiled by the thread groove exposed on the outer surface of the inner cylindrical portion 8a.

The mounting member 8 is attached to the mounting surface 4 by a screw member 9 via a mounting piece 8c extending inward from the base end of the inner cylinder portion 8a.

A glove backing 10 is interposed between the tip of the attachment member 8 and the flange 7 of the glove 5.

However, since the cover cylinder part 8b extends integrally with the inner cylinder part 8a, it is difficult to process and increases the processing cost. There was a problem in that it was difficult to improve the aesthetic appearance.

Further, there was a problem that water accumulated between the inner cylinder part 8a of the mounting member 8 and the cover cylinder part 8b.

Therefore, the purpose of this invention is to provide a lighting fixture that is easy to process, has high productivity, has few restrictions on processing, can obtain a free appearance, and does not have the problem of water accumulation. .

An embodiment of this invention is shown in FIGS. 2 and 3.

Note that the same parts as in the example of FIG. 1 are given the same reference numerals, and the explanation thereof will be omitted.

That is, in this lighting fixture, the mounting member 11 and the cover member 12 are provided separately.

The mounting member 11 is formed from a thin metal plate,
It is formed into a cylindrical shape with a female thread on the inner surface.

The mounting member 11 has a mounting piece portion 11 extending inward from the base end.
At a, the screw member 1 is attached to the mounting surface 4 through the backing 3.
It is installed with 3.

The tip of the attachment member 11 is in pressure contact with a glove backing 10 provided on the flange 7 of the glove 5.

The cover member 12 has a cylindrical shape that fits loosely around the outer periphery of the mounting member 11.

The axial length A of the cover member 12 is slightly shorter than the distance B between the glove backing 10 and the mounting surface 4, and a protrusion 14 is formed on the end surface of the cover member 12 facing the glove backing 10. are provided at appropriate intervals in the circumferential direction.

The cover member 12 contacts the glove backing 10 via the protrusion 14 and is held between the flange 7 of the glove 5 and the mounting surface 4.

Note that the diameter of the backing 3 is larger than the dowel member 11 and smaller than the cover member 12.

In this way, since the mounting member 11 and the cover member 12 are formed as separate bodies, the mounting member 11 and the cover member 12 can be easily processed, resulting in good productivity.

In addition, there are fewer restrictions on the processing of the cover member 12, and the cover member 12 can be formed into various shapes to improve aesthetics, such as forming the cover member 12 in a stepped manner as in the example shown in FIG. can.

In addition, since the cover member 12 contacts the glove backing 10 of the flange 7 of the glove 5 via the protrusion 14, a slight gap is created between the end of the cover member 12 and the glove backing 10, and this gap is It plays the role of draining water.

Therefore, there is no problem that water accumulates between the mounting member 11 and the cover member 12.

Further, for this reason, the backing 3 provided between the mounting member 11 and the mounting surface 4 can be formed to have a smaller diameter than the cover member 12 as in this embodiment, and therefore the outer circumference of the cover member 12 The backing 3 is not exposed at all, and the appearance is improved in this respect as well.

As described above, the lighting device of this invention has a mounting member into which the globe is screwed together, and a cover member that covers the outer periphery of the mounting member, and a cover member that covers the outer periphery of the mounting member, and a flange of the globe at the tip of the cover member. Since a protrusion that forms a slit for draining water is provided between the cover member and the cover member, processing is easy and productivity is high, and there are few restrictions on processing, and the cover member can be formed into any appearance. Furthermore, there are effects such as solving the problem of water accumulating between the cover member and the mounting member.
