[0002]

2. Description of the Related Art Hitherto, as an office ceiling illumination, an illumination device in which, for example, fluorescent lamp illumination devices of the same shape are connected in a line has been implemented. By the way, as shown in FIG. 6, sockets 2 are arranged inside both ends of a box-shaped lighting fixture main body 1 having a separately-opened lower surface as a conventional lighting fixture connection structure. Is provided with a reflecting mirror 5, and the lighting fixture body 1 and the reflecting mirror 5 are configured as a double structure. Further, a straight tube type fluorescent lamp, for example, is mounted between the sockets 2 at both ends. Also, a plurality of lighting fixtures configured as shown in FIG. 6 are supported on the ceiling surface of the office in a line, and a connecting fitting 3 is fitted between the lighting fixtures and connected and supported by a plurality of screws 4. .
In addition, the reflecting mirror 5 is configured so that the reflecting mirror 5 of the adjacent lighting fixture is partially overlapped with the reflecting mirror 5 and fastened with a plurality of screws 6. When a part of the end of the adjacent reflector is overlapped,
The connecting portion can be configured inconspicuously.

[0003]

However, according to the above-described structure for connecting lighting fixtures, since each lighting fixture is fastened with the screw 4, there is a drawback that it takes time to attach and detach the lighting fixtures. In addition, when performing maintenance and inspection of lighting equipment, the adjacent reflectors are overlapped.To maintain and inspect the lighting equipment at a specific location, it is necessary to remove the reflector of the adjacent lighting equipment. There are drawbacks that are complicated. Furthermore, in recent years, fluorescent lamp lighting fixtures for high-efficiency lamps (Hf lamps) having a small fluorescent lamp diameter have become widespread, and in order to save construction work, the depth of embedding of the lighting fixture body into the ceiling surface is small. Are proposed, and simplification of a mounting structure with a lighting fixture body is also required.

SUMMARY OF THE INVENTION The present invention has been made in view of the above points, and makes it possible to easily perform attachment and detachment of a lighting fixture, maintenance and inspection work of the lighting fixture, and work of attaching a reflector to a lighting fixture main body. It is another object of the present invention to provide a lighting fixture connecting structure in which the connecting portion of the lighting fixture is less noticeable.

[0005]
