Description

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]

Traditionally, ceiling-mounted multi-lamp lighting fixtures incorporating multiple straight tube fluorescent lights have been used, but 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,
No. 12841, Japanese Utility Model Publication No. 56-48927, Japanese Utility Model Publication No. 17871, Japanese Utility Model No. 17871, and Japanese Patent Publication No. 59-7162 are provided. Of these structures, in the former, the light body is screwed to the end 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. Also,
Even if the device is assembled on the floor and hung from the ceiling, installation work remains difficult because the device is quite large. Furthermore, since the main part of the latter device is constructed in one piece, there remain drawbacks such as the large size of the device and the complicated assembly work.

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 installing a bulb-shaped light body, but when installing a flat light body that incorporates an annular fluorescent lamp, it is difficult to align the light body. It is what it is.

[Purpose of the invention]

Therefore, the present invention provides a 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.

[Embodiments of the invention]

Hereinafter, basic embodiments of the present invention will be explained with reference to FIGS. 1 to 8. 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 numeral 100 denotes a lamp body incorporating an annular fluorescent lamp. In the embodiment, four lighting bodies 100 are combined to form one multi-lamp type lighting fixture l. FIG. 1 is an exploded assembly diagram of the embodiment seen from below, and FIG. 8 is an overview diagram of one lamp body 100 seen from an oblique direction 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.

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. t, power supply device 250
is arranged at the inner end of the attachment guide means 270 with the connection port facing outward. 280 is opened in the center of the base 200,
The base 200 is attached to the ceiling, and the power supply is connected to the base 200.
4. Connection hole for drawing inside. That is, the base 20
0 is a conventionally known method by using this connection hole 280, for example, Japanese Patent Application Laid-Open No. 54-56278, Japanese Utility Model Application No. 55-72705, or Japanese Utility Model Application No. 57-27615.
It is possible to attach only to the ceiling surface by using a recessed ceiling rosette that is embedded in the ceiling using a method such as a recessed ceiling rosette. Further, an annular fluorescent lamp, a ballast, a glow lamp, and various other holders are attached to the inner surface of the lamp base 110, and a lamp cover 1 that covers these is attached.
20 is assembled.

That is, by devising the shape 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-sectional shape of the staking guide means 270 is made into a rectangular C-shape, and the attachment means 170 By making the cross-sectional shape of the lamp body 10 into a rectangular shape that engages with the inner surface of the lamp body 10,
0 can be assembled onto the base 200.

That is, in the embodiment, a recessed ceiling rosette prepared in advance on the ceiling surface is used, and after the base 200 is first attached to the ceiling, the light is installed from the outer open end of the installation guide means 270 of the base 200. The attachment means 170 of the lamp body 100 is inserted, and the power receiving device 150 of the lamp body 100 is connected to the power feeding 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, on the base 200 attached to the ceiling,
The installation of the multi-lamp type lighting fixture 1 is completed by assembling the respective necessary lighting bodies 100 (four in the embodiment).

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 device l 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 makes installation work easy. This allows the installation work to proceed safely and reliably.

Furthermore, the lamp body 100 can be attached to the base 200 without using any particular screw tightening means by providing a suitable removal prevention means between the attachment guide means 270 and the attachment means 170. It's easy to do.

In the embodiment, as shown in FIG. 2, a base 200,
By appropriately selecting the dimensional relationship between the light body 100, the additional 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 1 that can be configured to be thin. At this time, when an annular fluorescent lamp is inserted into the lamp body 100, if the caps of the fluorescent lamps are arranged in the center of the multi-lamp type lighting apparatus 1, the multi-lamp type lighting apparatus 1
It is also 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 packed by stacking each member. 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, 801 is a packaging spacer that holds the base 200, 802 is a packaging spacer that holds the lamp 100, and 80B is a packaging box that houses these as a whole.
.

Although the multi-lamp type lighting fixture l of the embodiment has been described as a type that is attached only to the ceiling, it can be similarly configured as a type of hanging type lighting fixture.

Next, another embodiment of the present invention is shown in FIGS. 1 and 5 and 8.
・Explain an example. That is, FIG. 5 is an overview diagram of the embodiment, and FIG. 6 is an exploded assembly diagram. The features of this embodiment are that the lamp bodies 100 are arranged apart from each other and that a spacer 400 is provided to cover one base 200. It is at the point that I have set. To explain this, a connection hole 290 is bored in the center of the base 202 for arranging a recessed ceiling rosette.

208 is a screw hole used when directly screwing the base 202 to a ceiling frame, and 291 is a power plug connected to an embedded ceiling rosette (not shown).

The assembly of 0 is completed. At this time, if necessary, light body 1
A mechanism for stopping the removal of the 00 by 11 degrees can be provided in advance.

By attaching the spacer 400 to the base 202 in this manner, the distance between the lamp bodies 100 can be designed relatively freely, and a multi-lamp type lighting fixture 2 with a full jump rear feel can be obtained. Further, the eleventh and second of the spacer 400
Since the stepped portions 420 and 480 of the light body 100 can be provided with a function as a guide for attaching the lamp body 100,
With such a configuration, the lamp body 100 can be tied together smoothly without shaking.

Next, the present invention will be further explained with reference to FIG. This drawing shows a plan view of the multi-lamp type lighting fixture as viewed from below, and the configuration of each part of the structure shown in (a) and (b) has been clarified in the embodiments already described. The ones shown in Figures 7 (c) and (d) use a circular lamp 100', and the one shown in (c) K has an eight-lamp configuration, and the Go player 200' is octagonal. It is something that exists. In the case of such a multi-lamp type lighting fixture 8.4, the corner portions of the spacer 400' to which the base 200'K is attached are provided with stepped portions 480' having a circular shape and a stepped portion 480' having a 14 circular shape, respectively. This can be configured as a guide for attaching the lamp body 100'. Also,
It is also possible to take a decorative frame-like configuration as a human-shaped raised portion extending in eight or four directions at the center of the lower surface of the spacer 400'. Such a circular light body 100' is mounted on a base 200.
When assembling the lamp body 100', the linear installation guide means 270 and the installation means 170 described in the embodiment can be used. It is also possible to assemble the lamp body 100'. Furthermore, if the relationship between the stepped portion 480' of the spacer 400' and the external dimensions of the lamp body 100' is appropriately selected, the hook conventionally used can also be attached by a sealing mechanism. Of course, in this case, as many hooks and ceilings as there are lamp bodies 100' must be provided on the base 200'. Figure 8 (
