Second Embodiment FIG. 4 is a longitudinal sectional view of an essential part of the present invention, FIG. 5 is a partially cutaway bottom view of FIG. 4, and FIG. 6 is a sectional view taken along line 5A-5A of FIG.

The lamp Ab of the second embodiment comprises a lamp base frame 12, a mounting board 13, a packing 14, and a cover plate 15,
As in the first embodiment, the lamp Ab is assembled to the profile 1 such that the fluorescent lamp 5 is engaged in the recess 4 to constitute a second embodiment.

The lamp base frame 12 has a fixing piece 16 projecting from one end in the longitudinal direction of an opening end a of a main frame 12a formed of a long box-shaped frame body with a lower surface opening, and is parallel to the fixing piece 16. In this way, a locking piece 17 is protruded from the bottom piece 12a 'of the main frame 12a.

A pair of fluorescent lamp sockets 9, 9 are provided on the bottom piece 12a 'of the main frame 12a of the lamp base frame 12 so as to protrude toward the opening of the main frame 12a. A fluorescent lamp 5 is removably mounted, and a ballast 10 is attached to the other end corresponding to one longitudinal end of the opening end so as to be adjacent to the fluorescent lamp 5 or one socket 9. It is. That is, in the first embodiment, the lid plate 15
In the second embodiment, the fluorescent lamp 5 is mounted on the side of the lamp base frame 12 corresponding to the lamp base frame 6 of the first embodiment. The lamp 5 is pinched by a fingertip through a notch 18 provided on the side of the locking piece 17 of the side piece 12a ″ of the main frame 12a, and can be removed from the socket 9, that is, the lamp base frame 12.

The lamp base frame 12 provided with the fluorescent lamp 5 or the ballast 10 is provided on the mounting board 13 provided with a long window 19 along the recessed portion 4 of the profile 1, and the main frame 12 a is provided with the window 19. Assemble so that it can be freely disengaged and hinged.
, One end of the base frame 12 in the longitudinal direction is attached to the mounting substrate 13.
Connected to

The hinge 20 has one piece 20a attached thereto.
3 and the other piece 20b is welded to one end of the main frame 12a on the ballast 10 side, respectively, on the piece 13a existing on one end side in the longitudinal direction of the main body 12a, and erected between the lamp base frame 12 and the mounting board 13.
The lamp base frame 12 rotates about the axis of the hinge 20,
The rotation of the lamp base frame main frame 12a in the direction of the bottom piece 12a 'is performed by the other pieces 13 of the mounting board 13 facing the pieces 13a.
The fixed piece 16 comes into contact with b to be regulated.

The mounting board 13 assembled with the lamp base frame 12 via the hinge 20 is fixed to the flange piece 1a of the profile 1 constituting the bone frame 2 of the wall surface W with screws 8-4. By fixing the profile 1 with the screws 8-4 of the substrate 13, the lamp base frame 12 is attached to the profile 1 via the mounting substrate 13, and the hinge 20.
About the axis of the lamp as described above, and enters and exits the lamp base frame 12, that is, the recessed portion 4.

When the mounting substrate 13 is fixed (fixed) to the profile 1 by the screws 8-4, the rectangular ring-shaped packing provided with a window on the surface of the mounting substrate 13 like the mounting substrate 13. 14 is polymerized and fixed to the profile 1 together with the packing 14 and the mounting substrate 13. The packing 14 seals between the cover plate 15 and the mounting substrate 13.

A fixing portion 16 provided at one end of the lamp base frame 12 in the longitudinal direction is provided at a position where the fixing portion 16 overlaps with the other portion 13b of the mounting board 13, and a female member provided on the other portion 13b is provided. One end of the lamp base frame 12 which is hinged (attached to the mounting substrate 13 by the hinge 20) is attached to the screw 21 by screwing the screw 8-5 to the screw 21 through the fixing piece 16. It is fastened to the profile 1 via another piece 13b of the substrate 13. That is, by removing the screw 8-5 from the female screw 21, the lamp base frame 12 protrudes from the recessed portion 4 through the window 19, and the screw 8-4 is screwed to the female screw 21 to tighten the lamp base frame 12. Engages in the recess 4 so that the fluorescent lamp 5 is kept embedded in the recess 4.

The screw 8-5 is not detached from the fixed part 16 even if it is detached from the female screw 21 by the ring piece 22 interposed between the fixed part 16 and the other part 13b. Has become.

The other part 13b of the mounting board 13
The receiving piece 23 protruding in the direction of the concave portion 4 is provided continuously, and when the lamp base frame 12 rotates about the hinge 20 axis,
The engaging piece 17 provided on the base frame 12 is
3 (disposed on the rotation locus of the locking piece 17)
The rotation of the lamp base frame 12 is restricted. In this rotation restricted state, the notch 18 is detached from the recessed portion 4 and the fluorescent lamp 5 can be removed from the socket 9 (the lamp base frame 12), and the replacement work is performed. Becomes possible.

The cover plate 15 is made of a transparent synthetic resin, similarly to the closing plate 7 of the first embodiment, and is overlapped with the mounting substrate 13 or the packing 14 so as to coincide with the peripheral edge of the packing substrate. 6, the cover plate 15 is detachably attached to the mounting substrate 13, and the presence of the cover plate 15 prevents the fluorescent lamp 5 from contacting the article.

When it becomes necessary to replace the fluorescent lamp 5, the screw 8-6 is loosened to remove the cover plate 15 from the profile 1, and the screw 8-5 is loosened and removed from the female screw 21. As described above, the lamp base frame 12 rotates about the hinge 20 axis and protrudes from the recessed portion 4 so that the fluorescent lamp 5 can be replaced.
After replacement, return each member to the original position, and replace screws 8-5 and 8-6.
By tightening, the fluorescent lamp is again embedded.

In each of the embodiments, the problem of how to embed a fluorescent lamp using the recess 4 provided in the existing profile 1 is addressed. It is not necessary for the present invention to be implemented by forming a concave portion on the wall surface of the building positively, for example, the present invention may be implemented. It does not matter.

[0030]

The present invention has the configuration described above,
