Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a lighting integrated ceiling structure that allows a lighting fixture to be constructed without any special processing on the ceiling surface.

Conventionally used lighting fixtures have a structure that is relatively independent of the structure of the ceiling surface.
As a result, when installing lighting equipment, it was necessary to perform necessary processing on the ceiling surface.

Furthermore, after constructing the ceiling surface, extremely inefficient work was required, such as drilling holes in the ceiling board for installing lighting equipment.

Therefore, as a method to correct such inefficiency, a structure in which the ceiling surface is composed of T-bars and a ceiling plate placed between the T-bars has come to be widely adopted.

In this case, most of the lighting fixtures are installed between T-bars arranged in parallel along the length of the lighting fixtures, and the lighting fixtures have a drawback in that the mounting positions for the lighting fixtures are limited.

In addition, when using a structure in which both ends of a lighting fixture are placed on T-bars to support them, the lighting fixture itself is constructed with the idea of providing that strength, so if the main body structure is rigid, the lighting fixture Another problem is that the price is high.

In view of the above-mentioned circumstances, the present invention considers lighting fixtures as a part of the ceiling surface, fully considers the relationship with the T-bar and ceiling material as a ceiling system, and provides lighting that is streamlined in terms of construction and price. This project proposes an integrated ceiling structure.

In the ceiling structure of the present invention, a lighting fixture is configured on a ceiling surface in combination with a ceiling board, and the actual lighting fixture is formed by an equipment box equipped with a reflector, a socket, and the like.

Next, a lighting integrated ceiling structure according to the present invention will be explained using an embodiment shown in the drawings.

1 to 3 show a ceiling structure according to the present invention.

In the figure, reference numeral 1 denotes a frame member such as a T-bar, which is suspended from a ceiling slab by hanging fittings (not shown) and arranged in a cross shape or in parallel.

Reference numeral 2 denotes a ceiling plate placed between the frame members 1.1, and when no lighting equipment is installed, they are connected to each other by connecting fittings 7, such as splines, as shown in FIG.

As is clear from Fig. 3, when configuring a lighting fixture, a reflection lamp having a cross section of a U-shaped cross section and approximately the same length as the ceiling plate 2 is placed between the ceiling plates 2 and 2 placed at intervals. Attach plate 3.

Equipment boxes 4.5 with sockets are provided at both ends of the reflector plate 3, and fluorescent lamps 6 are mounted therein.

Note that the equipment box 4.5 can be fixed to the reflector 3 in advance, or can be attached after the reflector 3 is installed on the ceiling.

Since the dimensions of the lighting fixture are determined by the dimensions of the reflector plate 3, it is convenient to make these dimensions match those of the ceiling panel 2, for example, when installing the lighting fixture on the ceiling that has been constructed as shown in Figure 2. .

Next, a structure for attaching the reflecting plate 3 to the ceiling plate 2 will be explained.

Generally, a longitudinal side edge of the ceiling plate 2 is formed with a mortise groove 21 into which a connecting fitting 7 for connecting the ceiling plates 2 and 2 is inserted, as shown in FIG.

The connecting fitting 7 not only connects the ceiling plates 2.2 to each other, but also has a reinforcing effect to prevent the central portion of the ceiling plate 2 from sagging in the longitudinal direction.

In the present invention, as shown in FIG. 5, a locking edge 3131 is formed on the longitudinal side edges of a pair of side walls of the reflecting plate 3, and the locking edge 3131 is formed in the mortise groove 2121 of the opposing ceiling plate 2.2. 31.
31 to fix the reflecting plate 3.

As a result, the locking edge 31 of the reflector plate 3 is inserted into the mortise groove 21 along the entire length of the ceiling plate 2, and at the same time fixes the reflector plate 3, it also has the effect of reinforcing the ceiling plate 2 and preventing it from sagging. There is.

FIG. 6 shows a different formation structure of the locking edge 31 provided on the reflecting plate 3, in which the locking edge 31 is not simply formed in an L-shape, but is provided with a hanging portion 32 that once reaches the lower surface of the ceiling plate 2.

According to this structure, the reflector plate 3 is not formed from the middle of the ceiling plate 2, and the appearance is improved and the effect of reinforcing the edges is large.

In order to support the weight of the lighting equipment made up of the reflector plate 3 and other parts, there is a risk of sagging if only the ends of the lighting equipment are supported, so for example, as shown in FIG. A locking piece 33, 34 may be integrally provided at the end, and the locking piece 33, 34 may be locked to the T-bar 1 so that most of the weight of the lighting device is supported by the locking piece 33, 34.

As explained above, the lighting equipment is completed by attaching the reflector 3 between the ceiling plates 2.2 and attaching the equipment boxes 4.5 to both ends of the reflector 3.

By the way, this equipment box 4.5 is configured as follows, for example.

FIG. 7 shows an equipment box 4 that is only equipped with a socket 8.

This equipment box 4 includes a front plate formed with a through hole 41 for exposing the fluorescent lamp receiving surface of the socket 8, a bottom plate provided on this front plate so as to coincide with the lower surface of the ceiling plate 2, The front plate, the side plates provided on both sides of the bottom plate, etc. form a substantially box-shaped structure.

In the example shown in FIG. 7, the equipment box 4 is attached to the reflector 3 by screwing both side plates to the side plates of the reflector 3.

In addition, the locking pieces 33 and 34 are configured so that the weight of the lighting fixture is supported by the vertical piece of the T-bar 1 and cannot be easily removed, and are formed by pairing the L-shaped locking piece 33 and the second-shaped locking piece 34. ing.

This is a structure to prevent the locking pieces from overlapping each other when two reflecting plates 3.3 are butt-locked at the same location on the T-bar 1, and the reflecting plates 3.3 are positioned symmetrically. A pair of locking pieces integrally provided protruding from both ends of the side wall may be shifted to the left or right by at least the thickness of the plate forming the side wall to form a Z-shaped locking piece.

The equipment box 5 shown in FIG. 8 is constructed by screwing a socket box 51 that houses a socket 8, for example, in the same way as the equipment box 4 shown in FIG. For example, speakers, fire sprinklers, fire detectors, air conditioning equipment, etc. can be incorporated in a structure appropriate for each.

For example, when installing a speaker, a punching 52 is made on the equipment plate to match the speaker, and the speaker is mounted accordingly.

Of course, the reflector 3 is used for this installation, but the mounting hardware for each equipment is standardized,
It is also possible to provide mounting screw holes, knock holes, etc. on the reflecting plate 3 in advance.

Reference numeral 9 denotes a ballast box that houses the ballast. For example, if mounting holes 35 and 35 are formed in the side plate of the reflector plate 3 and both ends of the ballast box 9 are fitted into these holes and fixed, the ballast box 9 can be stabilized. This is advantageous in terms of strength to support the weight of the vessel.

36 is a wiring trough for passing the wiring from the ballast to the sokerato 8.

Furthermore, the equipment box 4.5 is not limited to the structure of this embodiment.
Any structure may be used as long as the socket 8 is attached to a predetermined position on the reflector plate 3 and necessary equipment including a stabilizer and the like is housed.

As explained in detail above, the present invention regards a lighting fixture as part of a system that combines it with the frame material, ceiling board, etc. that constitutes the ceiling surface, and eliminates the picture frame and body frame from the lighting fixture, making it easy to use. It is constructed as a collection of parts.

Therefore, for example, the reflecting plate, which forms the main body of a lighting fixture, is fixedly mounted using the mortise grooves in the ceiling board, and also has the effect of serving as a reinforcing material to prevent the ceiling board from sagging.

In addition, since the locking piece provided integrally with the reflector is locked to the T-bar, the weight of the lighting fixture is supported by the T-bar, which prevents the lighting fixture itself and the ceiling board from sagging. At the same time, it is possible to prevent the lighting equipment from falling due to vibrations such as earthquakes.

Moreover, since the positions of the pair of locking pieces provided at both ends of the reflector plate, which are symmetrically located, are shifted, the locking pieces will not overlap on the T-bar even when the lighting fixture is installed in a straight line. Can be stopped.

Furthermore, since the locking piece is made of plate material in the vertical direction, it has the advantage of being strong even if the plate thickness is thin.

Furthermore, since various equipment to be attached to the ceiling surface are attached using equipment boxes attached to both ends of the reflector, the ceiling surface is organized and a ceiling with a good appearance is formed.

Furthermore, since the lighting equipment is constructed from a combination of the minimum necessary parts of conventional lighting equipment, it can be constructed at a low cost as a whole.

Furthermore, if the dimensions of the reflector are made to match the dimensions of the ceiling board, there is an advantage that changing the position of lighting equipment, adding more, etc. can be carried out extremely easily.
