Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Application of the Invention] The present invention relates to a lighting fixture that is attached to a ceiling or the like.

[Background of the invention]

Ceiling-mounted multi-lamp lighting fixtures incorporating multiple straight tube fluorescent lights have traditionally been used, and recently,
Design registration No. 621645, which incorporates a Jumpria-like feel, for example, incorporates multiple annular fluorescent lamps.
Multi-light lighting equipment such as No. 1 has been proposed. However, the multi-lamp type lighting equipment having such a structure is large in size, and there remain difficulties in packaging, transporting, and installing the equipment.

Additionally, there are many structural constraints, making it difficult to design novel designs.

On the other hand, if you move the lamp body a certain distance from the center, you can get a pseudo-jump rear feeling, for example,
841, Japanese Utility Model Publication No. 56-48927, Japanese Utility Model Publication No. 55-17871, and Japanese Patent Publication No. 59-7162. Of these structures, in the former, the light body is screwed to the tip of an arm extending from the central base, but space is required above the light body for screwing. Therefore, there remains a problem in making it a thin multi-lamp lighting fixture that is attached only to the ceiling.

Furthermore, even if the device is assembled on the floor and hung from the ceiling, the installation work remains difficult because the device is large in size. Furthermore, in the latter case, since the main part is constructed in one piece, there remain drawbacks such as an increase in the size of the instrument and the need for multiple axes to be assembled.

Furthermore, Japanese Patent Publication No. 1988-88271 has been proposed as a Jumpria-type multi-lamp lighting device in which the lamp body can be freely attached and detached. This structure is convenient for attaching a bulb-shaped light body, but when attaching a flat light body that incorporates an annular fluorescent lamp, etc., it becomes difficult to align the light body. It is.

[Purpose of the invention]

Therefore, the present invention provides a lighting fixture that is easy to install.

[Summary of the invention]

That is, the present invention provides a base having a lamp attachment guide means on the lower surface, and an attachment means that engages with the attachment guide means on the upper surface, and is arranged close to the lower surface of the base. The present invention provides a lighting fixture comprising a flat lamp body.

[Embodiments of the invention]

Hereinafter, basic embodiments of the present invention will be explained with reference to FIGS. 1 to 3. FIG. 2 is a general view of the multi-lamp type lighting fixture 1 of the embodiment in a ceiling-mounted state, viewed obliquely from below, and 100 is a lamp body incorporating an annular fluorescent lamp.

In the embodiment, one multi-lamp type lighting fixture 1 is constructed by combining four lamp bodies 100. FIG. 1 is an exploded assembly view of the embodiment viewed from below, and FIG. 8 is an overview view of one lamp body 100 viewed obliquely from above. That is, 200 is a base that includes a plurality of power supply devices 250 and a lamp attachment guide means 270 on the lower surface. 150 is a power receiving device connected to the power feeding device 250, and the installation guide means 2
70 is disposed at the tip of the attachment means 170 that engages with the attachment means 70.

That is, the attachment guide means 270 are arranged radially along the diagonal lines of the base 200 so as to extend from the center of the base 200 to each corner. Further, the power supply device 250 is arranged at the inner end of the attachment guide means 270 with the connection port facing outward.

Reference numeral 280 is a connection hole opened in the center of the base 200 for attaching the base 200 to the ceiling and for drawing a power source into the base 200. That is, the base 200 can be assembled using the connection hole 280 by a conventionally known method, for example, Japanese Unexamined Patent Application Publication No. 54-56278 and Japanese Utility Model Application No. 55-727'0.
No. 5 or Utility Model Application Publication No. 57-27615, etc., using a recessed ceiling closet embedded in the ceiling, it is possible to attach only to the ceiling surface. Also,
The inner surface of the light body base 110 includes an annular fluorescent light, a ballast,
Glow lamps and various other holders are attached, and a lamp cover 120 is attached to cover them.

That is, by devising the shapes of the attachment means 170 so that the inner surface of the attachment guide means 270 receives the outer surface of the attachment means 170, specifically, the cross-sectional shape of the attachment guide means 270 is made into a rectangular C-shape. By making the cross-sectional shape of the attachment means 170 into a rectangular shape that is connected to the inner surface of the lamp body 10,
0 can be attached to the base 200.

In the embodiment, a recessed ceiling rosette prepared in advance on the Yai surface is used. After first attaching the base 200 to the ceiling, the base 200 is attached to the ceiling.

The power receiving device 1' 50 of the lamp body 100 is connected to the power feeding device 250 of the base 200 by inserting the attachment means 170 of the light body 100. At this time, the installation guide means 270
0 and the power supply device 250 while supporting the lamp body 100. The installation of the multi-lamp type lighting fixture 1 is completed by assembling the necessary light bodies 100 (four in the embodiment) to the base 200 mounted on one ceiling in this manner.

As described above, according to the embodiment, the multi-lamp type lighting fixture 1 is composed of a plurality of parts, which can be easily combined, so that the installation work can be easily performed. In other words, since the installation work of lighting equipment is almost always carried out upward using a stepladder, it is desirable that the parts carried up to the ceiling be as small as possible.
The fewer tightening points such as bolts and nuts, the better.

In this regard, in the embodiment, the multi-lamp type lighting fixture 1 is constructed by dividing it into a base 200 and a lamp body 100, and the individual size and weight of each component can be configured within a range that facilitates the installation work. This allows the installation work to proceed safely and reliably.

However, it is still possible to attach the lamp body 100 to the base 200 by providing a suitable means for preventing removal, especially screw tightening means, between the guide means 270 and the attachment means 170. It can be easily done without using it.

In the embodiment, as shown in FIG. 2, a base 200,
By appropriately selecting the dimensional relationship between the light body 100, the installation guide means 270, and the attachment means 170, the light body 10
0 can be placed in close contact with each other or with a very small gap between them.

In this way, by arranging a plurality of flat lamp bodies 100 close to the bottom surface of the base 200, sufficient brightness can be obtained.
Furthermore, it is possible to obtain a multi-lamp type lighting fixture l that can be configured to be thin. At this time, when an annular fluorescent lamp is incorporated into the lamp body 100, if the base of the ring-shaped fluorescent lamp is assembled in the center of the multi-lamp type luminaire 1, the multiple-lamp type luminaire 1
This is advantageous in terms of light distribution and appearance. That is, by arranging the fluorescent lamps in this manner, the light distribution is well balanced and a uniform luminous flux can be obtained throughout the room.

Further, in the embodiment, since the base 200 and the lamp body 100 can be configured to have substantially the same shape or size, they can be packaged by stacking each component. That is, an example of the packaging is shown in FIG. 4, and compared to conventional lighting equipment, it can be packed very compactly and is easy to transport and store. In addition,
In FIG. 4, for example, 301 is a packaging spacer that holds the base 200, 302 is a packaging spacer that holds the lamp 100, and 803 is a packaging box that houses these as a whole.

Although the multi-lamp type illuminator 1 of the embodiment has been described as a ceiling-mounted type, it can be similarly constructed as a hanging type illumination fixture.

Next, another embodiment of the present invention will be described with reference to FIGS. 5 and 6. That is, FIG. 5 is an overview diagram of the embodiment, and FIG. 6 is an exploded assembly diagram. The feature of this embodiment is that the lamp body 100
They are arranged apart from each other and are provided with a spacer 400 for covering the base 200. To explain this,
