It is pressed against the edge 228 and comes into contact with it.

At this time, the spring portion 37d is frictionally engaged with the long side side surface portion 222, and the spring portion 37e is frictionally engaged with the long side side surface portion 223. These urging forces and frictional forces strengthen the fixing of the light source unit 3 to the fixture body 2. In this way, the light source unit 3 is firmly fixed to the instrument main body 2 particularly in the vicinity of the center in the longitudinal direction, so that the light source unit 3 is caused by the weight of the light source unit 3 (particularly, in the vicinity of the center in the longitudinal direction in which the power supply unit 34 is arranged). It does not bend and there is no gap between the light source unit 3 and the accommodating recess 22. Therefore, in the luminaire 1, a gap is unlikely to occur between the light source unit 3 and the luminaire main body 2, and a beautiful appearance can be realized even when looking up from the lateral direction, which is the outside of the luminaire.

<2. Second embodiment>

It is pressed against the edge 228 and comes into contact with it.

At this time, the protruding portion 231 comes into contact with a part of the spring portion 37d, and the spring portion 37d and the protruding portion 231 are frictionally engaged with each other. The protruding portion 232 comes into contact with a part of the spring portion 37e, and the spring portion 37e and the protruding portion 232 are frictionally engaged with each other. As a result, since the number of frictionally engaged portions increases as compared with the first embodiment, the light source unit 3 and the instrument main body 2 can be more firmly fixed.

Further, since the spring portion 37e is placed on the upper surface of the protruding portion 231 and the spring portion 37d is placed on the upper surface of the protruding portion 232, the portion of the fixture body 2 that supports the light source unit 3 from below increases, and the fixture is mounted.

When the light source unit 3 is pushed up into the accommodating recess 22 of the instrument body 2 from the state where the light source unit 3 and the instrument body 2 are separated as shown in FIG. 9 (a), as shown in FIG. 9 (b). , The spring portions 37d and 37e of the fixing member 37 are elastically deformed so as to approach each other, and elastically urge the long side side surface portions 222 and 223 constituting the accommodating recess 22, and the support 31 opens the instrument main body 2. It is pressed against the edge 228 and comes into contact with it.

At this time, the outwardly protruding portions of the spring portion 37d and the spring portion 37e are fitted into the recesses 235 and the recesses 236, respectively, and are frictionally engaged with each other. As a result, since the number of frictionally engaged portions increases as compared with the first embodiment, the light source unit 3 and the instrument main body 2 can be more firmly fixed.

Further, since the spring portion 37e is placed on the lower surface of the recess 235 and the spring portion 37d is placed on the lower surface of the recess 236, the light source unit 3 is supported from below in the fixture body 2. The number of portions increases, and the load of the light source unit 3 applied to the fixture main body 2 is distributed to a plurality of portions.

Therefore, the possibility that the light source unit 3 is bent due to the weight of the light source unit 3 is further reduced, and the possibility that a gap is formed between the light source unit 3 and the accommodating recess 22 can be further reduced.

Instead of the recesses 235 and 236, holes may be provided in the long side side surface portions 222 and 223. In this case as well, as in the case of the concave portion, the outwardly protruding portions of the spring portion 37d and the spring portion 37e are fitted into the holes and are frictionally engaged.
