According to the invention of claim 2, in addition to the function of the luminaire of claim 1, the opening peripheral end of the globe 1 is closer to the mounting surface than the flange portion 4d of the appliance body 4. The protrusion margin can be changed, and the gap between the peripheral edge of the opening of the globe 1 and the mounting surface can be changed to further provide a feeling of close contact with the mounting surface, thereby radiating to the mounting surface side. The amount of light changes.

Further, in the invention described in claim 3, in addition to the function of the luminaire according to claim 1 or 2, the dimensional accuracy between the contact portion 1a and the flat portion 1e of the globe 1 is Since it is determined by the machining accuracy of the mold, variation is unlikely to occur, and therefore excessive force is less likely to be applied to the glove 1 when the glove 1 is attached.

[0014]

1 and 2 show a first embodiment of the luminaire of the present invention. This luminaire mainly comprises a glove 1, a packing 2, a fixture body 4, and a nut 7. Is configured.

The glove 1 is made of pressed glass,
The outer shape has a substantially frusto-conical shape with an opening on one side, and a side wall 1f is formed so that the inner surface spreads from the bottom portion 1c, which is a flat portion 1e, toward the opening side, and at the bottom portion 1c. Is provided with two insertion holes 1g. Further, inside the peripheral edge portion of the opening, a recess is provided so as to cut out the corner portion from the opening side to form a contact portion 1a of the instrument body 4.

The instrument main body 4 is below the peripheral edge of the main body base 4a which is attached so as to substantially contact the ceiling, which is the attachment surface, in a direction substantially parallel to the main body base 4a, that is, the ceiling which is the attachment surface. A flange portion 4d extending outward in a direction substantially parallel to the surface is provided, and a rubber packing 2 is attached to the tip of the flange portion 4d. Also, the main body base 4a
A stepped support column 4c whose end is screwed is provided on one center line of the, and a rubber contact member 4e, for example, is attached to the stepped portion 4f.

In the luminaire thus constructed, the globe 1 is pushed up from the lower surface side to the luminaire main body 4 mounted on the ceiling, which is the mounting surface, while aligning the tip of the support column 4c with the insertion hole 1g to raise the tsuba. The packing 2 attached to the portion 4d is brought into contact with the contact portion 1a, and the contact member 4e at the tip of the support column 4c and the flat portion 1e of the bottom portion 1c are brought into contact with each other,
The glove 1 is mounted by screwing a nut 8 onto the tip of the support column 4c protruding from the glove 1 and tightening the nut 8.

With such a configuration, in the luminaire in this embodiment, when the mounting surface is the ceiling, when the luminaire is viewed from the ceiling lower surface side, the luminaire body 4 is hidden by the globe 1. You will not be able to see it, and you will get a feeling of close contact with the ceiling, which is the mounting surface. In other words, from the lower surface side, only the globe 1 can be seen, the gap is not conspicuous with the ceiling, and the globe 1 feels as if it is floating on the ceiling. Also, the ceiling surface, which is the mounting surface, is appropriately radiated from the end portion of the globe 1 located outside the collar portion 4d and wraps around to reduce the luminance ratio between the surface of the globe 1 and the ceiling surface. , It is possible to make glare less noticeable.

Furthermore, the dimensional accuracy of the dimension h between the abutting portion 1a and the flat portion 1e of the globe 1 is determined by the machining precision of the mold, and therefore is unlikely to vary, and therefore the glove 1 is excessively attached when the glove 1 is attached. Even if a force is hard to be applied and the dimensions of the glove 1 are varied, if the hardness and compression allowance of the packing 2 and the contact member 4e are set appropriately, the variation is absorbed and excessive bending stress is applied to the glove 1. Will not occur. This effect is particularly remarkable when the globe 1 is made of a material such as press glass which is easily damaged.

FIG. 2 shows a second embodiment of the luminaire of the present invention, which is different from the first embodiment in the glove 1 and the supporting column 4c, and the other ones in the first embodiment. The configuration is similar to that of the above-mentioned embodiment.

The glove 1 is made of pressed glass,
The outer shape has a shape of a substantially quadrangular pyramid that is open to one side, and a side wall 1f is formed so as to widen from the peripheral end of the bottom portion 1c, which has a flat portion 1e, toward the opening side. A step portion 1d is formed on the inner wall of the side wall 1f to form a stepwise cross section, and one insertion hole 1g is provided at a substantially central portion of the bottom portion 1c.
The support pillar 4c which is erected on a is provided at one substantially central portion thereof. Further, the step portion 1d on the side of the opening peripheral end, which is one of the step portions 1d of the side wall 1f of the globe 1, serves as the contact portion 1a of the instrument body 4.

Because of the above-mentioned structure, in the lighting equipment of this embodiment, in addition to the effect of the first embodiment, in addition to the flange portion 4d of the equipment main body 4 at the peripheral edge of the opening of the globe 1. By changing the margin of protrusion to the ceiling surface side, which is the mounting surface, the gap between the peripheral edge of the opening of the globe 1 and the ceiling can be changed, and in addition, a feeling of close contact with the ceiling of the lighting fixture can be obtained. By changing the amount of light emitted to the ceiling surface side that is the mounting surface, it is possible to further reduce the luminance ratio between the surface of the globe 1 and the ceiling surface that is the mounting surface, and to make glare less noticeable.

In each of the above-mentioned embodiments, the globe 1 is made of press glass and is described as having a truncated cone shape and a truncated pyramid shape, respectively, but the present invention is not limited to this, and the translucent resin is used. May be formed by
Further, the shape thereof is not limited to the above-mentioned one, and may be any shape. Further, in each of the above embodiments, the ceiling is illustrated as the mounting surface, but the present invention is not limited to this, and the mounting surface may be a wall surface inside or outside the room.

[0024]

Since the present invention is constructed as described above, the present invention according to claim 1 is concealed by the glove so that the main body of the luminaire can be seen when the luminaire is viewed from substantially the front side thereof. It is possible to get a feeling of close contact with the mounting surface of the lighting fixture without feeling the gap between the mounting surface and the mounting surface side, and also from the end of the glove located outside the collar part, etc. It is possible to reduce the luminance ratio between the glove surface and the mounting surface by making the light radiate and wrap around, making it difficult to sense glare.

According to the invention of claim 2, in addition to the effect of the invention of claim 1, a margin of protrusion at the peripheral edge of the opening of the glove to the mounting surface side of the flange of the instrument body is provided. By changing the gap between the peripheral edge of the opening of the globe and the mounting surface, you can get a closer feeling to the mounting surface and change the amount of light emitted to the mounting surface side. , It is possible to further reduce the brightness ratio between the surface of the glove and the mounting surface, and to make glare less noticeable.

According to the invention of claim 3, in addition to the effect of the invention of claim 1 or claim 2, the dimensional accuracy between the abutment portion and the flat portion of the globe is determined by machining the mold. Since it is determined by the accuracy, it is difficult for variations to occur, so
Excessive force is less likely to be applied to the glove when it is worn.
