Description

[Detailed Description of the Invention] [Technical Field] This invention relates to lighting equipment such as ceiling lights.

[Background technology]

FIG. 4 shows a conventional example. In the figure, 1 is the main body of the device, 2 is a female screw part integrated on the outer periphery of the main body 1, 3 is a socket base, 4 is a socket, 5 is a lamp, 6 is a glove, 7 is a male screw part provided on the glove 6, 8 is a fixed part such as a ceiling surface. The instrument body 1 is fixed to the fixing part 8 with wood screws or the like.
The glove 6 is detachably attached to the instrument body 1 by screwing its male threaded portion 7 into the female threaded portion 2 of the instrument body 1.

In this conventional example, since the shoulder part 9 of the glove 6 is separated from the fixing part 8, external force F (the direction is not limited to that shown in the figure) may occur due to, for example, a duster flapping or an inadvertent touch. When this acts on the glove 6, the moment M is intensively applied to the corner 10 between the male threaded portion 7 and the shoulder 9, causing the problem that this corner 10 cracks.

In particular, the corner portion 10 tends to become thin during molding, and when it is thus thin, the above-mentioned problem is likely to occur.

[Purpose of invention]

The purpose of this invention is to provide a lighting fixture that does not cause the globe to crack as described above.

[Disclosure of invention]

The lighting fixture of this invention includes a fixture body, a globe attached to the fixture body, and a shoulder portion formed on the globe so as to be substantially located on an extended surface of the mounting surface of the fixture body. It is something.

This configuration has the following effects. That is,
When the instrument main body is attached to the fixing part on its attachment surface, and the glove is attached to the instrument body, the shoulder of the glove either comes into contact with the attachment surface, or even if it is separated, the distance is small.

Therefore, when an external force acts on the glove,
The shoulder of the glove abuts the fixed part and resists the external force at this abutment point. That is, external force is prevented from acting as a moment on the attachment portion of the glove to the instrument body, and the glove is also prevented from cracking at this attachment portion.

Embodiment An embodiment of this invention will be described based on FIG. The shoulder portion 9a of the globe 6 is bulged toward the instrument body 1 along the axial direction of the lamp 5 compared to the conventional example. This shoulder portion 9a is continuous in an annular shape, and is located substantially above the extension surface of the mounting surface 1a of the instrument main body 1 relative to the fixing portion 8 such as a ceiling surface. That is, when the male threaded part 7 of the glove 6 is completely screwed into the female threaded part 2 of the instrument body 1, it is flush with the extension surface, or is slightly separated from the extension surface, or the male threaded part 7 is connected to the female thread part 2 of the instrument body 1. Make sure they are flush before they are completely screwed together.

Thereby, in a predetermined wearing state, the shoulder portion 9a is either in contact with the fixing portion 8 or is slightly separated from it.

Therefore, even if an external force F acts, the external force F
is received at the contact portion between the shoulder portion 9a and the fixed portion 8, and is not transmitted to the corner portion 10, and the corner portion 10 is effectively protected from the external force F even if it is thin.

Furthermore, since the shoulder portion 9a covers the female screw portion 2 of the instrument body 1, the external appearance is better than that of the conventional example.

The rest is the same as the conventional example (Fig. 1), so
Identical parts are given the same reference numerals, and their explanations are omitted.

As shown in FIG. 2, when the glove 6 is attached to the fixing part 8 above the instrument body 1, it is susceptible to external force F. The lighting equipment of this invention fully exhibits its advantages in such cases.

Note that the shape of the globe 6 may be cylindrical, polygonal cylindrical, or
It can be arbitrarily shaped such as a truncated cone shape or a polygonal truncated pyramid shape. Examples 2 and 3 are shown in FIG.

Instead of the glove 6 of the type in which the male threaded part 7 is internally screwed into the female threaded part 2, the female threaded part 2 is used as the male threaded part, and the female threaded part which is externally screwed into this is directly connected to the fixing part 8 (extension surface) from the shoulder part 9a. ), and a glove formed on the part that hangs down may also be used.

[Effect of idea]

According to this invention, even if an external force is applied to the glove, this is absorbed by the abutment between the fixing portion and the glove shoulder, thereby preventing the glove from cracking.
