Locks to the instrument body 40. With such an engaging structure, the cover 20 can be easily attached to the instrument main body 40. The cover 20 may be attached to the instrument main body 40 by a method other than engagement, such as screwing.

The surface of the cover 20 has light reflectivity. The surface of the cover 20 has light reflectivity by being coated with, for example, a white paint, and reflects the light emitted from the first main surface 32b of the light guide plate 32. This makes it possible to improve the utilization efficiency of the light emitted from the first main surface 32b of the light guide plate 32. It is not essential that the surface of the cover 20 has light reflectivity.

The surface of the cover 20 includes an inclined surface 21. At least a part of the inclined surface 21 is located between the power supply device 50 and the light guide plate 32. The height of the inclined surface 21 from the base portion 41 is lower as the portion located closer to the light guide plate 32.

FIG. 7 is an exploded perspective view of the instrument main body 40 and the mounting members 80a and 80b.

If the mounting members 80a and 80b are fixed to the fixture body 40 in advance, it is possible to save the trouble of mounting the mounting member as compared with the method of mounting the mounting member to the structure and then mounting the lighting fixture to the mounting member. .. That is, a lighting fixture 10 that is easy to install is realized.

Further, when the instrument main body 40 is attached to a structure having some unevenness, if the portion of the instrument main body 40 facing the structure partially protrudes, the instrument main body 40 should avoid the unevenness of the structure. Can be done.

Here, when the instrument body 40 is manufactured by extrusion molding, it is difficult to partially project the instrument body 40 in the longitudinal direction. On the other hand, if the mounting member 80a separate from the instrument body 40 is fixed to the instrument body 40, the mounting portion 81a of the mounting member 80a can be projected from the instrument body 40. Similarly, if the mounting member 80b is fixed to the instrument body 40, the mounting portion 81b of the mounting member 80b can be projected from the instrument body 40.

In the luminaire 10, the mounting member 80a is fixed to the inside of the base portion 41, and the mounting portion 81a projects from the opening 41d provided in the base portion 41 to the outside of the base portion 41. Similarly, the mounting member 80b is fixed to the inside of the base portion 41, and the mounting portion 81b projects to the outside of the base portion 41 from the opening 41e provided in the base portion 41. The mounting members 80a and 80b are fixed to the base portion 41 by, for example, screwing, but may be fixed to the base portion 41 by adhesion or welding.

As described above, according to the mounting member 80a and the mounting member 80b, even when the fixture body 40 is manufactured by extrusion molding, the portion of the lighting fixture 10 facing the structure can be partially projected. Therefore, it becomes easy to attach the lighting fixture 10 while avoiding the unevenness of the structure.

On the outer surface of the base portion 41, a plurality of elongated ribs standing on the outer surface and along the longitudinal direction of the base portion 41 are arranged side by side in the lateral direction of the base portion. The plurality of ribs are specifically the first rib 41a, the second rib 41b, and the third rib 41c. Each of the openings 41d and 41e is provided in a portion between the second rib 41b and the third rib 41c in a plan view.

Thereby, each of the mounting portion 81a protruding from the opening 41d and the mounting portion 81b protruding from the opening 41e can be obscured from the X-axis direction by the second rib 41b and the third rib 41c. That is, the appearance of the lighting fixture 10 in the installed state can be improved.
