(Function) In the indirect lighting device of the present invention, a lamp is disposed at a corner of a main body having a substantially rectangular planar shape, facing inward in the planar shape, and a cover body covering the lamp is attached to a corner of the main body. By arranging the cover only on the lower surface of the main body, it is possible to widen the portion of the opening on the lower surface of the main body that is not covered by the cover body. When in use, the light from the lamp is reflected by a reflector inside the main body and irradiated to the outside through the opening. At this time, since the cover body is small as described above, the darkened portion on the lower surface of the main body becomes small.

(Embodiment) Hereinafter, the configuration of an embodiment of the indirect lighting fixture of the present invention will be described based on FIGS. 1 to 3.

Reference numeral 21 denotes a main body, and the main body 21 has a substantially rectangular planar shape, for example, a square or a rectangle, and is box-shaped with an open bottom surface (top surface in FIG. 2).

Further, a flange portion 23 is formed on the lower surface of the main body 21 at an edge portion around the opening portion 22 .

Reference numeral 26 denotes a reflector, and the reflector 26 has a substantially rectangular planar shape, a substantially trapezoidal side profile, and a box-like shape with an open bottom. It is built into the main body 21 so as to form a concave shape. Note that each of the four corners 27 of the reflecting plate 26 has a chamfered shape. Furthermore, the reflective plate 26
A flange portion 28 is formed at the peripheral edge of the bottom surface.

Moreover, on the inner surface of the main body 21,
A socket fixing plate 31 having a substantially right-angled isosceles triangle shape is horizontally fixed to each corner by welding or the like. That is, the two other than the oblique sides of this socket fixing plate 31
A joining piece 32 joined to the inner surface of the main body 21 is provided on the side.
is formed by bending.

Lamp sockets 33 are fixedly attached to the lower or outer surfaces of these socket fixing plates 31, respectively. Further, for example, a stabilizer 34 is attached to the inner surface on the opposite side of the socket fixing plate 31, and this stabilizer 34 is attached to the inner surface on the opposite side of the socket fixing plate 31.
4 and the lamp socket 33 are electrically connected by wiring. Note that the stabilizer 34 may be arranged at other positions within the main body 21. Then, each corner 27 of the reflector 26 is attached to the oblique side of the outer surface of each socket fixing plate 31.
A flange portion 28 is fixedly attached with screws or the like.

36 is a short compact double fluorescent lamp consisting of two U-shaped tubes arranged side by side. And this fluorescent lamp 3
6 has a cap 37 provided at one end thereof, which is detachably connected to each of the lamp sockets 33, and the tip side faces inward in the planar shape of the main body 21. In particular, in the illustrated embodiment, each fluorescent lamp 36 located at each corner in the main body 21 is located on a diagonal line of the planar shape of the main body 21, and the fluorescent lamps 36 located on the same diagonal line are separated from each other. Facing each other.

Reference numeral 41 denotes a nearly rectangular frame made of non-transparent material;
1 has a substantially triangular cross section and has an inner circumferential wall 42 joined to the inner surface of the main body 21. The frame body 41 is fixedly attached to the main body 21 with screws or the like so as to cover the entire periphery of the flange portion 23 thereof. Further, 43 is a cover body made of an opaque material or a semi-transparent material. It has at the periphery. The cover body 43 is fixed to each corner of the inner peripheral side of the frame body 41 by screws or welding, respectively,
Each cover body 43 assembled to the frame body 41 in this manner is located at each corner of the lower surface of the main body 21, and completely covers each of the fluorescent lamps 36 from the opening z2 side. .

Next, the operation of the above embodiment will be explained.

When assembling, first, attach the socket fixing plate 31. The main body 21, in which the ballast 34 and the lamp socket 33 are integrally assembled, is embedded and fixed in a mounting surface such as a ceiling surface, and a power supply line is wired.

In addition, when it is attached to a ceiling surface, the direction shown by the arrow in FIG. 2 is downward.

Next, each fluorescent lamp 36 is attached to each lamp socket 33, respectively. In FIG. 1, the upper right side of the figure shows a state in which the fluorescent lamp 36 is attached, and the lower right side shows a state in which the fluorescent lamp 36 is removed.

Next, a cover body 4 is attached to the peripheral edge of the lower surface of the main body 21.
3 are integrally assembled together from below, and are fixedly attached with screws or the like at a portion of the interior of the main body 21 that is not visible from the outside through the opening 22. In addition, in FIG. 1, the right side of the illustration shows a state in which the frame body 41 is attached, and the left side shows a state in which the frame body 41 is removed.

Then, when in use, from the fluorescent lamp 36 to the reflector 26,
The light irradiated towards is reflected by the reflection plate 26,
The light is irradiated to the outside through the portion of the opening 22 of the main body 21 that is not covered by the frame 41 and the cover 43, that is, the opening at the center of the lower surface of the main body 21. In addition, when the cover body 43 is made of an opaque material, this cover body 43
This completely blocks direct irradiation from the fluorescent lamp 36 to the outside. On the other hand, when the cover body 43 is made of a semi-transparent material, the light from the fluorescent lamp 36 passes through the cover body 43 while being diffused to such an extent that the shape of the fluorescent lamp 36 cannot be seen.

According to the above configuration, short compact double fluorescent lamps 36 are disposed at each corner of the main body 21 having a substantially rectangular planar shape, facing inward of the planar shape, and these fluorescent lamps 36
Since the cover body 43 is disposed only at the corner of the main body 21 so as to cover the opening 22 on the lower surface of the main body 21, assuming that the external planar shapes of the main bodies 21 and 1 are the same size,
The opening inside the frame 41 including the portions not covered by the cover bodies 43, that is, the cover bodies 43, can be widened. Of course, the frame 41 that does not cover the fluorescent lamp 36 can be made thinner than before. As a result, the lighting effect can be improved, and the frame 41
Moreover, it becomes possible to improve the design balance between the cover body 43 and the opening inside thereof. In addition, the cover body 4
3 can be made smaller, the dark portion of the lower surface of the main body 21 can be made smaller during illumination, and the appearance when illuminated can be improved.

In this way, the design quality can be improved, and the product can be differentiated in terms of appearance.

By the way, in the conventional indirect lighting fixtures shown in FIGS. 4 to 6, the lamp socket chassis 4 is attached to the main body 1 closer to the opening 2 than the reflector 3.
There are many parts involved in assembly, which makes installation and removal troublesome and increases costs.

However, in the above embodiment, the reflector plate 26 is later screwed to the socket fixing plate 31 fixed to the main body 2I in advance, so the structure is simple, and the socket fixing plate 31 is attached to the main body 21 during installation and removal. The mounting and dismounting operations are therefore simplified. Nevertheless, the socket fixing plate 3 with the screwed part of the reflector 26! Since it is covered by the cover body 43, the appearance is not spoiled. Also, main body 2
Both the ballast 34 and the lamp socket 33 in the connector 9.1 can be left connected regardless of whether the lighting equipment is installed or removed.
10 becomes unnecessary and the wiring work becomes easier. Further, by eliminating the need for the conventional large chassis 4 and connectors 9 and 10, weight and cost can be reduced. Furthermore, since the double fluorescent lamp 36 is used as a light source, the length of this lamp 36 can be shortened, and the holding fitting 8 for holding the tip of the compact fluorescent lamp 7, which is conventional, is also unnecessary.

In the above embodiment, the fluorescent lamps 36 are provided at each of the four corners of the main body 21, but the lamps 36 may be provided only at two opposing corners. The lamps 36 may be provided only at one corner.

Further, in the above embodiment, the cover body 43 has a fan shape, but the cover body 43 may have a rectangular shape, a triangular shape, or the like.

〔Effect of the invention〕

According to the present invention, a lamp is disposed at a corner of a main body having a substantially rectangular planar shape, facing inward in the planar shape,
Since the cover body is placed at the corner of the opening on the bottom of the main body to cover this lamp, even if the external dimensions of the main body are the same, it is easier to cover the lamp than the one that is located at the opening of the main body and covered by the cover body. It is possible to secure a wide area that is not covered, that is, the substantial opening, thereby improving the illumination effect, as well as improving the balance between the substantial opening and the cover body. By making it smaller, it is possible to reduce the portion that becomes dark on the lower surface of the main body when illuminated, and it is possible to improve the appearance design.
