Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a fluorescent lighting device comprising a frame that can be used for ceiling edges, etc., and a lighting member attached to the frame.

Recently, by using a plurality of leveling structures that are suspended from a ceiling slab at a distance from each other in the same plane, lighting members are placed between two frame bodies that are supported at a distance from each other so as to be orthogonal to the leveling structures. Fluorescent lighting devices with suspended lights have become popular.

However, when the lighting member is suspended from the frame, a portion of the lighting member protrudes above the upper surface of the frame, which often makes it impossible to connect the frame directly to the leveling structure that supports the frame. As a result, this was the cause of deep pockets.

In view of this, recently, lighting components such as ballast sockets have been made into blocks, and these blocks have been further divided into two blocks.
Some structures have been developed in which the fluorescent lamp is placed over the frame of the book, placed outside both ends of the fluorescent lamp, and the lighting member does not protrude much above the frame. It had to be determined based on the block, which made the positioning work complicated, and there was also a problem in terms of protecting the wiring between the lamp sockets.

The present invention improves these conventional drawbacks,
A fluorescent lighting device that does not protrude upward from the frame, reduces the protrusion toward the opposing frame, makes it easy to position the lamp socket spacing, and does not cause any problems in protecting the wiring. In order to provide a lamp socket, a socket stand, a reflective cover, and a lighting component block are each separately attached to a hanging wall surface of a frame so as to be slidable in the longitudinal direction of the frame, and the spacing between the lamp sockets is regulated by the reflective cover. It is characterized by what it did.

Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings. Reference numeral 1 denotes a frame body, and the lower surface of a plurality of leveling structures 2 suspended from a ceiling slab (not shown) in the same plane and spaced apart from each other. They are connected to each other by a connecting member 21 so as to be orthogonal to the direction in which the leveling structure is disposed, and two of them are arranged in parallel with a narrow interval to form a set.

Its cross section has a downward hook shape on the top of the hanging wall surface 11. The frame itself has a means 12 for attaching the frame itself, a downward hook shaped portion 13 is provided on the top of the hanging wall surface 11, and a downward hook shaped portion 13 is provided on the upper surface of the bottom side 14. It has an upward hook-shaped portion 15 facing the upward hook-shaped portion 13, and further has a bottom side 14,
An upward standing portion 16 is located outside the upward hook-shaped portion 15.
It has an inverted form with a .

3 is a socket base, whose upper end 31 is inserted into the downward hook-shaped part 13 of the frame body 1 and whose lower end 32 is inserted into the upward hook-shaped part 15 of the frame body 1, so that it can be slid in the longitudinal direction of the frame body 1. The hanging wall surface 11 of the frame body 1
The lamp socket 4 has mounting means 33 in the middle thereof.

The insertion depth of the upper end 31 is set to such an extent that the lower end 32 can escape from the upward hooked portion 15 of the frame when inserted to the deepest point relative to the depth of the downward hooked portion 13 of the frame. It is desirable to do so.

Reference numeral 5 denotes a reflective cover, the cross section of which is composed of a vertical upper end 51, a horizontal base part 52 following this, and a downwardly inclined part 54 that is bent at an acute angle from its tip to reach a lower end 53. Lamp socket insertion holes 5 are provided near both left and right ends of the inclined descending portion 54.
5, and the spacing between the end side edges 56 of these two lamp socket insertion holes 55 is the same as the back spacing when the lamp socket 4 is properly installed. It is inserted into the barbed portion 13, and the lower end 53 is engaged with the upward standing portion 16 of the frame 1, and is attached to the hanging wall surface 11 of the frame 1 so as to be slidable in the longitudinal direction of the frame 1.

In this attached state, the socket base 3 can be attached by overlapping the upper end 31 and lower end 53 of the socket base 3.

When the reflective cover 5 is superimposed on the socket stand 3, the two lamp sockets 4 are inserted and attached to the two insertion holes 55 separately.

Reference numeral 6 denotes a lighting component block, which is attached via legs 61 to the hanging wall surface 11 of the frame 1 so as to be slidable in the longitudinal direction of the frame 1 in the same way as the socket stand 3 described above.

62 indicates a ballast.

Reference numeral 7 denotes an intermediate cover which is suspended between the frames 1 and 1, and its cross section includes a horizontal bottom surface 71 and hanging walls 72 that stand up from both edges thereof.
An edge 7 formed horizontally on the outside of the top of the hanging wall 72
3, and when installed, the bottom surface 71 covers the lower surface of the lighting component block 6, and the edge 73 is placed on the horizontal base 52 of the reflective cover 5.

Reference numeral 8 denotes a flat reflecting plate, whose both edges are placed and supported on a horizontal platform 52 of the reflecting cover.

Reference numeral 9 denotes a ceiling plate, which is placed and supported on the upper surface of the bottom side 14 of the frame body.

10 is a fluorescent lamp. Since the present invention is constructed as described above, all lighting components such as the lighting component block 6 and the reflective cover 5 are placed at a height below the upper surface of the frame 1, and the mounting of the frame itself obstructs the means 12. It is arranged so that there is no

Further, since the reflective cover 5 and the lighting component block 6 are separated, the protrusion toward the opposing frame 1 can be made small.

The lamp sockets 4 are defined by reflective covers 5 at appropriate intervals, and at the same time, the reflective covers 5 also cover the wiring 19 along the frame 1.

Moreover, since both the lamp socket 4 and the reflective cover 5 are slidable along the longitudinal direction of the frame 1, their positions can be easily adjusted.

Furthermore, it is also possible to attach a lighting member to only one side of the frame 1, and if applied to a room where the line of sight is almost fixed, such as a classroom, illumination with less glare can be provided.

Even when lighting members are attached to the frame 1 on both sides and ballasts for two lights are used, it is possible to arrange the lamps lit by each ballast in tandem and create a wiring circuit for each column on one side, which saves power. Even when half of the lights are turned off for reasons of illumination, the ballast can be used evenly and the illuminance can be illuminated with less unevenness.

Note that it is also possible to attach lighting members to both side walls of one frame 1.

The material of the reflective plate 8 is not limited to any particular material, and for example, it may be made of the same material as the ceiling plate, which can be easily processed on-site.

As a result, the interval between frames was widened regardless of the lighting member,
A fluorescent lamp illumination device with a large degree of freedom can be obtained, such as being able to be configured to serve as an inspection port by removing the reflector plate 8.

As explained above, this idea consists of attaching a pair of socket stands and lighting component blocks to the hanging wall surface of the frame separately so that they can slide in the longitudinal direction of the frame, and a reflective cover with socket insertion holes at both ends. is attached to the hanging wall surface of the frame in such a way that it overlaps with the socket base and can be slid in the longitudinal direction of the frame, so there is no protrusion of the lighting member above the frame, and the space between the opposing frames Protrusion in the direction can also be suppressed, the lamp socket can be easily positioned, and the wiring can be protected.
