However, openings are formed at both ends of the glove, non-light-transmitting end plates are attached to the openings, and the end plate is attached to the main body with the glove attached. Lighting fixtures of the type located on the outer surfaces of both ends of the body do not appear to be very well known.
In this type of luminaire, it is difficult to completely eliminate the gap between the end plate and the outer surface of the main body. Therefore, it should be noted that there is a problem to be solved such that the lamp light leaks from the gap to the ceiling or the wall and the appearance is poor. Then, in view of such a problem to be solved, an object of the present invention is to provide a lighting device in which lamp light hardly leaks from the gap to a ceiling or a wall.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, embodiments of the present invention will be described. However, these are merely exemplary embodiments adopted based on the present invention, and the present invention is limited to matters unique to only the embodiments. The technical scope of the present invention must be determined based on the matters stated in the claims or matters that are substantially equivalent thereto.

The illustrated embodiment includes a non-translucent main body (made of metal) 3 attached to a ceiling (or wall) 1 and provided with an incandescent lamp 2 on the lower surface, and a lower surface of the main body 3 while covering the lower surface. A semi-transparent glove (made of synthetic resin) 6 having a non-translucent end plate (made of metal) 5 attached to the opening 4 is provided, and a gap 7 is formed between both end portions of the glove 6 and the end plate 5. A lighting fixture. Also, a gap 1 is provided between the upper end 9 of the glove 6 and the main body 3.
There is 0. And the inner surface 8 of the globe 6 is a fine rough surface. The light from the lamp 2 is reflected by the globe 6
When the light is reflected by the inner surface 8, the light may be diffused appropriately. Further, such a rough surface may be formed on the outer surface of the globe 6.

More specifically, a hanging rosette 11 is fixed to the ceiling 1, and a protrusion at the lower portion of a hook plug 12 hooked and electrically connected to the hanging rosette 11 is passed through the main body 3. On the other hand, a ring-shaped fixture 13 is attached from the lower surface of the main body 3 by a locking means, and the main body 3 is attached to the ceiling 1. From the hooking plug 12, a power cord 14 passed through the projecting portion of the connector 1 is fixed to a control block 15 fixed to the lower surface of the main body 3.
6 is connected by a connector 17. A human body sensor block 19 is provided on the lower surface of the control block 15 via a support 18.
, And a human body sensor 20 is held in the interior so as to freely swing. The human body sensor block 19 is a frame 2 attached to a window hole formed at the lower end of the globe 6.
It is positioned to face 1. The control block 15 and the human body sensor block 19 are located on one side, and the lamp 2 and its socket 22 are located on the other side, with the attachment 13 located at the center of the main body 3 as a center.

The globe 6 has a substantially semi-cylindrical shape, and its upper end 9 is formed as an inward bent piece, and a light-shielding piece (made of metal) protruding inward near the upper end of the inner surface of the end plate 5. 24
Is fixed. Holes 25 formed at both ends of light shielding piece 24
A screw 27 is screwed into the glove 6 from the upper end 9 through holes 26 formed at both ends of the upper end 9 of the glove 6, and the substantially semicircular end plate 5 is attached to the glove 6. Then, attachment pieces 28 at the upper end of the end plate 5 are attached to both ends of the main body 3 from outside. This attachment is performed by screwing a thumbscrew 29 from the outside to the main body 3 through the attachment piece 28. Note that the elastic packing 30 is attached to the upper surface of the main body 3 and is brought into contact with the ceiling 1, thereby contributing to the mounting stability of the main body 3.

The present embodiment described above has a non-translucent main body 3 attached to a ceiling (or wall) 1 and provided with a lamp 2 on the lower surface, and a lower surface of the main body 3 and openings 4 at both ends. A semi-transmissive glove 6 to which a non-translucent end plate 5 is attached, wherein the end plate 5 is positioned on outer surfaces of both ends of the main body 3 with the glove 6 attached to the main body 3. An inward light-shielding piece 24 is provided on an inner surface of the end plate 5, and substantially blocks light leaking from a gap between the end plate 5 and outer surfaces of both ends of the main body 3. is there.

According to the present embodiment, an inward light-shielding piece 24 is provided on the inner surface of the end plate 5 to substantially shield light leaking from a gap between the end plate 5 and the outer surfaces at both ends of the main body 3. Lamp light can hardly leak from the gap to the ceiling or the wall 1, and the appearance can be improved. In addition, since the upper surface of the light shielding piece 24 abuts on the lower surfaces of both ends of the main body 3 in a state where the globe 6 is mounted on the main body 3, when the globe 6 is to be mounted on the main body 3, the light shielding piece 24 is located at both ends of the main body 3. At the stage where the glove 6 comes into contact with the lower surface, the operation for fixing the glove 6 to the main body 3 can be smoothly performed.

There is a gap 7 between both ends of the globe 6 and the end plate 5, and a gap 10 between the upper end 9 of the globe 6 and the main body 3. This is useful for reducing the temperature rise in the globe 6, and the gaps 7 and 10 are intentionally provided to make the gaps less noticeable. And
Since the inner surface 8 of the globe 6 is made to be a fine rough surface, the light is appropriately diffused particularly when the light from the lamp 2 of the point light source is reflected by the inner surface 8 of the globe 6. Then, the gap 7,1
The reflected light leaking from 0 is softened, and the light projected on the ceiling 1 is diffused and inconspicuous, so that a sense of discomfort can be eliminated. In particular, when leaking from the gap 7, the ceiling 1 on the side of the end plate 5 is dark because the end plate 5 is not light-transmitting, so that it is possible to remarkably reduce the conspicuousness.
