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

[Background of the invention]

Ceiling-mounted multi-light lighting fixtures incorporating multiple straight tube-shaped fluorescent lights have traditionally been used, but recently, multiple annular lighting fixtures have been used that add a chandelier-like feel to this. Multi-light lighting fixtures such as Design Registration No. 621645 incorporating fluorescent lights have 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 light body a certain distance away from the center,
For example, Utility Model Publication No. 55-32341, Utility Model Publication No. 43927, 1982, or Utility Model Publication No. 17371, 1977, and Special Publication No. 7162, 1977, provide a pseudo-chandelier-like feeling. 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. from,
There are still some difficulties in making it a thin multi-lamp type lighting fixture that is attached to the ceiling. Furthermore, even if the device is assembled on the floor and hung from the ceiling, the installation process remains difficult because the device is quite large. Furthermore, since the main part of the latter is constructed in one piece, the device becomes larger and
However, there are still some drawbacks such as complicated assembly work.

Furthermore, with chandelier-shaped multi-light lighting equipment,
As a light body that can be attached and detached freely,
No. 38271 is proposed. This structure is
This is convenient for installing light bulb-shaped lamps, but when installing flat lamps incorporating annular fluorescent lamps, it becomes difficult to align the lamps.

[Purpose of the invention]

Therefore, the present invention provides a compact multi-lamp type 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, an attachment means that engages with the attachment guide means on the upper surface, and a plurality of flat lamps disposed close to the lower surface of the base. The present invention provides a multi-lamp type lighting fixture comprising a lamp body. Further, when the mounting means of the lamp body is connected to the mounting guide means of the base, the wiring connection between the two can be made automatically.

[Embodiments of the invention]

Below, basic embodiments of the present invention are shown in Figures 1 to 3.
This will be explained using figures. FIG. 2 is a general view of the multi-lamp type lighting fixture 1 of the embodiment in a ceiling-mounted state, viewed diagonally from below, and 100 is a lamp body containing an annular fluorescent lamp. In the embodiment, four lighting bodies 100 are combined to form one multi-light lighting fixture 1.
It consists of FIG. 1 is an exploded assembly diagram of the embodiment as seen from below, and FIG. 3 is an overview diagram of one lamp body 100 as seen from an oblique direction from above. That is, 20
0 is a base provided with a plurality of power supply devices 250 and a lamp attachment guide means 270 on the lower surface.
Reference numeral 150 denotes a power receiving device connected to the power feeding device 250, and is arranged at the tip of the attachment means 170 that engages with the attachment guide means 270. That is, the attachment guide means 270 are arranged radially along diagonal lines of the base 200 so as to extend from the center to each corner. Further, the power supply device 250 is disposed at the inner end of the attachment guide means 270 with the connection port facing outward. 280 is an opening in the center of the base 200, the base 200 is mounted on the ceiling, and the power supply is connected to the base 200.
This is a connection hole for drawing into 0. That is,
The base 200 can be connected by using the connection hole 280 using a conventionally known method, for example, Japanese Patent Application Laid-Open No.
No. 56278, Utility Model No. 55-72705, or Utility Model No. 57
- It is possible to attach directly to the ceiling surface using a recessed ceiling rosette that is embedded in the ceiling using methods such as No. 27615. In addition, the light body base 1
An annular fluorescent lamp, a ballast, a glow lamp, and various other holders are attached to the inner surface of the lamp 10, and a lamp cover 120 is further assembled to cover these.

That is, by devising the shapes of both so that the inner surface of the attachment guide means 270 receives the outer surface of the attachment means 170, specifically, the cross section of the attachment guide means 270 is made into a rectangular C-shape, and the cross section of the attachment means 170 is made into a rectangular C-shape. The lamp body 100 is connected to the base 20 by having a rectangular shape that engages with the inner surface of the lamp body 100.
It can be assembled to 0.

That is, in the embodiment, after first attaching the base 200 directly to the ceiling using a recessed ceiling rosette prepared in advance on the ceiling surface,
The attachment means 170 of the light body 100 is inserted through the outer open end of the attachment guide means 270 of the base 200, and the power receiving device 150 of the light body 100 is connected to the power supply device 250 of the base 200. At this time, the attachment guide means 270 connects the power receiving device 150 and the power feeding device 25
0 connection while supporting the lamp body 100. In this way, the installation of the multi-lamp type lighting fixture 1 is completed by assembling the respective necessary lighting bodies 100 (four in the embodiment) to the base 200 attached to the ceiling.

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 most lighting equipment installation work is done using a stepladder, etc., facing upwards, it is desirable that the parts carried up to the ceiling be as small as possible, and it is better to have fewer tightening points such as bolts and nuts. . 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. In addition, the base 20
The lamp body 100 can be easily attached to the 0 by providing an appropriate retaining means between the attaching guide means 270 and the attaching means 170, without using particular screw tightening means or the like.

In the embodiment, as shown in FIG.
0. By appropriately selecting the dimensional relationship of the attachment means 170, the lamp bodies 100 can be disposed in close contact with each other or with an extremely small gap between them. In this way, by arranging a plurality of flat lamps 100 close to the bottom surface of the base 200, the multi-lamp lighting fixture 1 has sufficient brightness and can be configured to be thin. can be obtained. 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, it is possible to It is also advantageous from the point of view. 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 packed by stacking each member. In other words, an example of packaging is shown in Figure 4, but compared to conventional lighting equipment,
Can be packed up very compactly and transported,
It also makes storage easier. 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 303 is a packaging box that houses these as a whole.

As described above, the base 200 is fixed to the ceiling surface. In order to make this fixation stable, the base 2
00 has a flat shape that spreads in the horizontal direction. Although this point is disadvantageous in terms of miniaturization, in the present invention, the attachment guide means 270 is disposed within the range of the lower surface of the flat base 200 to effectively utilize the lower surface. The latter point is advantageous in making the device more compact; however, if the mounting guide means 270 were placed outside the outer periphery of the base 200, the device would become larger and would be disadvantageous in terms of packaging.

As is already clear, in this embodiment, the power supply device 250 is provided at a position closest to the center of the base in the attachment guide means 270. Further, the power receiving device 150 is provided at a position closest to the center of the base in the attachment means 170. For this reason, the lamp body 100
