Conventionally, as an example of this type of two-light type lighting fixture, there is one described in Japanese Patent Application Laid-Open No. 55-166804. As shown in FIG. 5 , this lighting fixture 1 is attached to a chassis 2 which is a fixture body fixed to a ceiling or the like by screwing or the like, and an inverted mountain-shaped reflector 3 is attached by screwing or the like, for example, two straight tube types. The bases at both axial ends of the fluorescent lamps 4 and 5 are sandwiched in the axial direction by two pairs of sockets 6 and 7 and are detachably mounted.
[0003]
[Problems to be solved by the invention]
However, in such a conventional lighting fixture 1, as shown in FIG. 6 , the sockets 6 and 7 are attached to the metal socket base 9 together with the glow socket 8 by screwing or press-fitting. After attaching to the chassis 2 by screwing or the like, it is necessary to attach the reflector 3 to the chassis 2 in a state in which each of these sockets 6 and 7 protrudes outward from each opening 3a of the reflector 3 having the outer plate. is there. Further, since the reflecting plate 3 has a pair of left and right outer plates 3b and 3c, the number of processing steps during manufacturing is large, the workability is low, and the sockets 6 and 7 are correctly positioned in the openings 3a. The assembling work to be inserted is not easy. As described above, the conventional lighting fixture 1 has a large number of parts. For this reason, there are many assembly man-hours at the installation site of the lighting fixture 1, and the assembly workability is low, and the mounting workability is further low. .
[0004]
In addition, in the case where the chassis 2 is warped or the mounting ceiling wall is slightly curved, a gap is formed between the chassis 2 and the mounting ceiling wall. There is a problem in that dust accumulates in the gap and stains the lighting fixture 1.
[0005]
Therefore, the present invention has been made in view of such circumstances, and an object thereof is to provide a lighting apparatus having a small number of parts and high workability in processing, assembly, and construction.
[0006]
Another object of the present invention is to provide a luminaire that can hide a gap when it is formed with a mounting wall such as a ceiling.
