SUMMARY OF THE INVENTION The present invention is intended to improve such a problem. Due to its structure, the fixture is directly fixed to the ceiling surface of the room, and a pair of lamp sockets is attached and fixed to both ends. The fixed-length lamp support stay, the straight tube fluorescent lamp inserted and supported between the lamp sockets facing each other, and the central portion of the lamp support stay are assembled to the fixture and integrated in the middle. The lamp support stay is provided with a fixed stay receiving frame and an insert joint of a fixed length interposed between adjacent lamp support stays to connect and connect a plurality of lamp support stays in series. A hollow straight pipe with a rectangular cross section through which the electrical wiring cord can be conducted is used, while the insert joint is a gate-shaped cross section that slidably fits the lamp support stay. In addition, the intermediate socket cover is assembled and integrated into the central part of the fixed length, and the insert joint is inserted into the hollow inside of the adjacent lamp support stays freely, and the intermediate socket covers cover the lamp sockets of both lamp support stays. The main feature is that the insert joint is fixed in a retaining state by screwing fixing screws from above both lamp support stays while keeping the cover state.

[0008]

According to the above construction of the present invention, the supporting stay of the straight tube type fluorescent lamp is assembled and fixed to the mounting fixture by the stay receiving frame at one central portion thereof. When a plurality of such fluorescent lamps are connected and connected in series, it is sufficient to prepare only the insert joint. There is no need to prepare seeds, and construction work can be performed extremely easily.

Further, it is possible to freely install the front end portion of the frontmost fluorescent lamp in a floating state in which the front end portion of the fluorescent lamp is overhanging forward from the hanging wall of the ceiling. As a result, the depth dimension of the ceiling surface is reduced. Even if the difference varies from section to section, it is not necessary to prepare several types of fluorescent lamps having different lengths and use them in combination. Regardless of the change in the depth dimension, it is sufficient to always connect one type of fluorescent lamp having the same number of Watts in series, and in that sense, the construction workability can be significantly enhanced.

Further, if the fluorescent lamp supporting stay is adapted to be assembled and fixed to a mounting fixture at one position in the central portion of the stay receiving frame, the 雖 also has a space between the lamp supporting stays adjacent to each other in the front and rear. Since an insert joint of a certain length is inserted in the hollow inside of both support stays, it can be inserted and removed freely. The result is that the lamp sockets and lamp holders attached to both support stays are beautifully covered by the intermediate socket cover of the insert joint without any fear of rattling or lateral shake. It is done.
