板７により構成されている。3 and 4 show an example of a conventional lighting device for indirect lighting. The device is composed of a device body 1 having an opening 2 on the lower surface, a socket 3 attached to the inner side thereof, a lamp 4 mounted on the device 3, a light shielding plate 5, a decorative frame 6 and a reflecting plate 7.

に固定して取付けられている。As shown in FIG. 3, the lamp 4 is a single-ended fluorescent lamp and is located in the vicinity of the opening 2 of the main body of the lamp. The lamp 4 is attached so that its longitudinal direction is parallel to the end of the opening. Attached to the upper end 5a of the shading plate 5 and the lower end 6a facing the opening 2 side of the decorative frame 6 facing the upper end 5a, which is more than an extension line (for example, line A-A in FIG. 3). It is provided on the lower side and on the back surface 5b side of the light shielding plate 5. The light-shielding plate 5 is attached to the decorative frame 6 facing the opening 2 side of the device body 1 in the shape of a substantially truncated pyramid that is opened vertically, and together with the decorative frame 6 by the frame mounting spring 8, the device body 1 is attached. Locked in. Further, the reflector 7 is located on the side of the fixture body 1 with respect to the lamp 4, and is attached to the fixture body 1 by means of screws or the like.
It is fixedly attached to.
このように構成された照明器具では、ランプ４からの器

ない。In the luminaire constructed in this way, most of the direct light from the lamp 4 to the lower surface of the luminaire strikes the back surface 5b of the light shielding plate 5 and is reflected, and further reflected by the reflection plate 7 to be guided to the front surface of the luminaire. In addition, a small amount of the direct light from the lamp 4 to the lower surface of the fixture is reflected by the front surface 5c of the light shielding plate 5,
Guided to the bottom side of the luminaire. On the other hand, the light from the lamp 4 toward the upper surface of the device is reflected by the reflection plate 7, and a part of the light is further reflected by the reflection plate 7 or the front surface 5b of the light shielding plate 5 and guided to the lower surface side of the device. Therefore, the direct light emitted from the lamp 4 does not directly illuminate the lower surface side of the instrument body 1.

粧枠６の輝度が低く暗いためにこの部分が大きく見え、
照明器具の見栄えが非常に悪いという欠点があった。By the way, in the conventional luminaire for indirect illumination having such a structure, a non-transparent material such as a coated steel plate is used for the light shielding plate 5 to shield the direct light from the lamp 4 to the lower surface side of the equipment. However, since only the reflected light is emitted from the bottom surface of the lighting fixture, there is a problem that the efficiency of the fixture is poor. When the lighting device in the lighting state is viewed from the lower surface side, the high-brightness reflection plate 7 that reflects light and guides the light to the lower surface side of the device and the light-shielding plate 5 and the decorative frame 6 that have low brightness are clear because almost no light hits. The light-shielding plate 5 and the decorative frame 6 have low brightness and are dark, so this part looks large.
There was a drawback that the lighting fixtures looked very bad.
本考案は、前記背景に鑑みてなされたものであり、その
目的は器具効率の向上をはかるとともに、遮光板を目立

具を提供することにある。The present invention has been made in view of the above background, and an object of the present invention is to provide a lighting fixture for indirect lighting that improves the efficiency of the fixture and makes the light-shielding plate inconspicuous so that it looks good.

ある。In order to solve the above-mentioned problems, the present invention provides a lighting fixture for indirect lighting, which has the same structure as the conventional example except for the shading plate 5, and includes a shading plate 5 located on the fixture body opening 2 side with respect to the lamp 4. It is formed of a translucent material, and is configured so that the inside of the fixture cannot be seen through so that only a part of the direct light of the lamp is transmitted, and the brightness of the shading plate 5 during lighting when viewed from the bottom side of the fixture It is characterized in that it is made substantially the same as the brightness.

板７の境界がわかりにくくなり、このため遮光板５が目
立たなくなる。Since the lighting device is configured as described above, in this lighting device, the direct light from the lamp 4 to the lower surface side of the device is the back surface 5b of the light shielding plate 5.
A part of the light is transmitted and guided to the lower surface side of the device, and a part of the light is reflected and hits the reflecting plate 7, where it is reflected and guided to the lower surface side of the device. Further, the light from the lamp 4 to the upper surface of the fixture is reflected by the reflection plate 7, and a part of the light is further reflected by the reflection plate 7.
Alternatively, the light is reflected by the front surface 5c of the light shielding plate 5 and guided to the lower surface side of the device. Therefore, the direct light from the lamp 4 does not directly go out to the lower surface side of the fixture body, and the brightness of the light shielding plate 5 is made substantially the same as the brightness of the reflecting plate 7, so that the boundary between the light shielding plate 5 and the reflecting plate 7 is It becomes difficult to understand, and thus the light shielding plate 5 becomes inconspicuous.

したものである。FIGS. 1 and 2 show an embodiment of the present invention, which is constructed in substantially the same manner as the above-mentioned embodiment except the light shielding plate 5. The light shielding plate 5 is located on the side of the fixture body opening 2 with respect to the lamp 4 and is formed of a translucent material such as an opaque material such as milky white. The brightness of the plate 5 is substantially the same as the brightness of the reflection plate 7.

の見栄えが良くなる。Because of the above configuration, the lamp 4
Direct light from the device to the device opening 2 side hits the back surface 5b of the shading plate 5 and a part thereof is transmitted to illuminate the lower surface of the device, and a part of the light is reflected and hits the reflection plate 7 to be reflected and guided to the lower surface of the device. . Further, the light from the lamp to the upper surface of the device is reflected by the reflection plate 7, and a part of the light is further reflected by the reflection plate 7 or the front surface 5c of the light shielding plate 5 and guided to the lower surface side of the device. Therefore, the direct light from the lamp 4 does not directly go out to the lower surface side of the fixture body, and not only the reflected light but also the transmitted light is used for indirect illumination, so that the fixture efficiency is improved, and further, the lighting fixture lighting. Since the brightness of the light-shielding plate 5 therein is set to be substantially the same as the brightness of the reflecting plate 7, the boundary between the light-shielding plate 5 and the reflecting plate 7 becomes difficult to see, which makes the light-shielding plate 5 inconspicuous and makes the lighting fixture look good.
なお、上記実施例ではランプ４としては片口金蛍光灯を

勿論である。Although the single-base fluorescent lamp is shown as the lamp 4 in the above embodiment, the present invention is not limited to this, and any lamp such as a straight tube fluorescent lamp or a halogen lamp may be used. It is needless to say that not only the ceiling-embedded type shown in (1) but also any type such as a ceiling directly-mounted type may be used.
また、上記実施例では遮光板５は不透明の透光性材料を
用いて形成したが、本考案はこれに限らず、透明な材料

一としたものであっても良い。Further, in the above embodiment, the light shielding plate 5 is formed by using an opaque translucent material, but the present invention is not limited to this, and the surface is formed by using a transparent material and the surface is formed into a so-called prism shape. The shape of the light shielding plate 5 may be substantially the same as that of the reflecting plate.
本考案は前述の通り構成されているので、遮光板からラ
ンプ直射光の一部が透過するため器具効率が向上すると
ともに、反射板と遮光板の輝度が略同一であるため遮光
板が目立たなくなり、点灯中の照明器具の見栄えが良く
なる。Since the present invention is configured as described above, part of the direct light of the lamp is transmitted from the shading plate, which improves the efficiency of the equipment and makes the shading plate inconspicuous because the brightness of the reflection plate and the shading plate are substantially the same. , The appearance of the lit lighting fixtures will be improved.
