For example, four lighting devices 5 may be attached to the building material 4. In this case, four through holes 17 a are formed in the first member 17. That is, four concave portions 4 a are formed in the building material 4. Moreover, in the form mentioned above, although the end surface of the illuminating device 5 and the end surface of the building material 4 are parallel when viewed from the front-rear direction, the end surface of the illuminating device 5 and the end surface of the building material 4 are viewed from the front-rear direction. And do not have to be parallel.

(Modification 5 of building material with lighting device)
FIG. 12 is a front view for explaining the configuration of the first member 17 according to another embodiment of the present invention.

  In the form mentioned above, the 1st member 17 may be comprised by the 3rd member 21 and the 4th member 22, as shown in FIG. That is, the building material 4 may include the third member 21 and the fourth member 22. The third member 21 and the fourth member 22 are formed in a flat plate shape having an L shape.

  Further, as described above, the lighting device 5 is formed in a square flat plate shape, and among the four end surfaces of the lighting device 5, two end surfaces parallel to each other serve as the first end surface 5a, and the remaining ones. Assuming that the two end faces are the second end faces 5b, the third member 21 has two contact faces 21a as the first contact faces that come into contact with one of the two first end faces 5a. A contact surface 21b as a second contact surface that contacts one of the second end surfaces 5b of the second end surface 5b is formed. The fourth member 22 includes a contact surface 22a as a third contact surface that contacts the other first end surface 5a of the two first end surfaces 5a, and the other of the two second end surfaces 5b. And a contact surface 22b as a fourth contact surface that contacts the second end surface 5b.

  The contact surfaces 21a, 21b, 22a, 22b are formed in a planar shape. The width of the contact surfaces 21a and 22a (the width in the left-right direction in FIG. 12) is slightly shorter than the length of the first end surface 5a of the lighting device 5 (the length in the left-right direction in FIG. 12). The width of the contact surfaces 21b and 22b (the vertical width in FIG. 12) is longer than the length of the second end surface 5b of the lighting device 5 (the vertical length in FIG. 12). One end of the contact surface 21b is connected to the lower end surface of the third member 21 in FIG. 12, and one end of the contact surface 22b is connected to the upper end surface of the fourth member 22 in FIG. The other end of the contact surface 21b is connected to one end of the contact surface 21a, and the other end of the contact surface 22b is connected to one end of the contact surface 22a.

  A portion between the other end of the contact surface 21a and the upper end surface of the third member 21 in FIG. 12 is a facing surface 21c facing a part of the contact surface 22b (a part on the upper end side in FIG. 12). A portion between the other end of the surface 22a and the lower end surface of the fourth member 22 in FIG. 12 is a facing surface 22c facing a part of the contact surface 21b (a part on the lower end side in FIG. 12). In the modification shown in FIG. 12, the third member 21 and the fourth member 22 are combined to form a through hole 17a as an arrangement hole in which the lighting device 5 is arranged.

  Thus, the illumination device 5 is a surface-emitting illumination device that is formed in a square flat plate shape and emits light from one side in the thickness direction of the illumination device 5. Of the end faces, if two end faces parallel to each other are defined as the first end face 5a and the remaining two end faces are designated as the second end face 5b, the building material 4 is the first of the two first end faces 5a. A contact surface 21a as a first contact surface that contacts the first end surface 5a and a contact surface 21b as a second contact surface that contacts one of the two second end surfaces 5b are formed. The contact surface 22a as a third contact surface that contacts the three members 21 and the other first end surface 5a of the two first end surfaces 5a and the other second end surface 5b of the two second end surfaces 5b. And a fourth member 22 formed with a contact surface 22b as a fourth contact surface in contact with the third member. Combined with product 21 and the fourth member 22, a through hole 17a of the mounting holes to the lighting device 5 is arranged may be formed.

  In this case, by making the width of the contact surfaces 21a, 22a slightly shorter than the length of the first end surface 5a, the contact surfaces 21b, 22b and the second end surface 5b can be reliably brought into contact with each other. The contact surfaces 21a and 22a and the first end surface 5a can be reliably brought into contact with each other. Therefore, it becomes difficult to form a gap between the side surface of the through hole 17 a of the building material 4 and the lighting device 5. In addition, in the form mentioned above, if the through-hole 17a is formed in the 1st member 17 with sufficient precision, it will become difficult to form a clearance gap between the side surface of the through-hole 17a of the building material 4, and the illuminating device 5, but in this case The processing cost of the 1st member 17 becomes high.

The building material 4 may be formed in a rectangular flat plate shape, and the electrical contact 25 may be disposed on the end surface of the building material 4. In this case, by fixing the building material 1 with the lighting device to the structural material 2, the two adjacent building materials 1 with the lighting device can be easily electrically connected using the electrical contacts 25. . Therefore, it becomes possible to simplify the process of the wiring for supplying electric power to the illuminating device 5. In this case, if electric power is supplied to one building material 1 with a lighting device, it is possible to supply power to the remaining building material 1 with a lighting device.
