Further, in the above-described first to third embodiments, the two panel bodies constituting the lighting structure according to the present invention are composed of the first panel 10 and the second panel 20 constituting the door (joint) 1. The two panel bodies constituting the lighting structure according to the invention may form a part of the door (joint) 1.

Further, in the first to third embodiments, the translucent member 30 includes a first translucent portion 31 and a second translucent portion 32, and is configured to have a cross-shaped cross section. The translucent member according to the above is not limited to this, and may not include the second translucent portion 32.

Further, in the first to third embodiments, the exposed surfaces 31a and 31b of the first translucent portion 31 are inclined with respect to the facing end surface so as to be separated from the second panel 20 toward the end in the front-rear direction. However, the inclination direction of the exposed surfaces 31a and 31b of the first translucent portion 31 is not limited to the above-mentioned direction. For example, the exposed surfaces 31a and 31b of the first translucent portion 31 are directed toward the end in the direction opposite to that of the first to third embodiments, that is, in the front-rear direction, so as to approach the second panel 20 with respect to the facing end surface. It may be tilted. Even in this case as well, it is assumed that the entire first translucent portion 31 is housed in the concave groove 11 so as not to protrude from the concave groove 11.

Further, in the above-described first to third embodiments, the exposed surfaces 31a and 31b are roughened and formed on the rough surface, but the finish of the exposed surfaces 31a and 31b is not limited to the rough finish. For example, the exposed surfaces 31a and 31b may be polished. When the exposed surfaces 31a and 31b are polished, the light transmitted through the door 1 through the translucent structure 5 is diffused and invisible as in the first to third embodiments, and is straight from the openings 8a and 8b. Looks like going to. As a result, to a person who sees the door 1 from the front side, it seems that linear light is emitted from each of the openings 8a and 8b.
