In addition, the upper case 31 is provided between the pair of convex portions 43 and protrudes into the interior 51 (see also FIG. 2) of the instrument body 20 and the second inner dowel (inner dowel) 52 and the second inner dowel (inner dowel). ) 53.

  A pair of convex portions 43 are linearly extended along both side portions of the upward side surface 41 facing the downward surface 13 of the building material 12. The convex portion 43 protrudes from the concave portion 44 of the upward side surface 41 toward the downward surface 13 and has a top portion 43 </ b> A that can contact the downward surface 13. The protrusion 43 is formed such that the protrusion dimension L1 is equal to or larger than the cross-sectional maximum dimension (an oblong dimension in the case of VVF) of the wiring 16.

A concave portion 44 is provided between the pair of convex portions 43 on the upward side surface 41. The concave portion 44 is formed so as to face the downward surface 13 without contacting and to be recessed with respect to the pair of convex portions 43 so that the wiring 16 can be accommodated. Specifically, the wiring 16 drawn out from the through hole 15 in the downward surface 13 is accommodated in the space 55 between the recess 44 and the downward surface 13.
A lead-in hole 45 is opened substantially at the center in the longitudinal direction of the recess 44. The wiring 16 accommodated in the space 55 between the recess 44 and the downward surface 13 is drawn into the interior 51 of the instrument body 20 from the drawing hole 45. The drawn wiring 16 is connected to the terminal block 17.

As shown in FIG. 6, by forming a space 55 between the concave portion 44 and the downward surface 13, the wiring 16 drawn out from the through hole 15 of the downward surface 13 is accommodated in the space 55, and the drawing hole 45 of the concave portion 44 is accommodated. Can be routed.
Thereby, the lighting fixture 10 can be attached to the desired position (arbitrary position) of the downward surface 13 irrespective of the drawing position of the wiring 16 on the downward surface 13 (that is, the position of the through hole 15).

As shown in FIGS. 3 and 5, a first outer dowel 46 and a second outer dowel 47 are provided between the pair of convex portions 43. The first outer dowel 46 and the second outer dowel 47 protrude in the same direction as the protruding direction of the pair of convex portions 43 (that is, the direction of the downward surface 13 of the building material 12). An insertion hole 57 is provided in the top portion 46 </ b> A of the first outer dowel 46, and an insertion hole 58 is provided in the top portion 47 </ b> A of the second outer dowel 47.
The first outer dowels 46 and the second outer dowels 47 are formed so that the projecting dimensions L <b> 2 are not more than the projecting dimensions L <b> 1 of the projecting portions 43 with the recess 44 as a reference.

  As shown in FIG. 7, the insertion hole 57 of the first outer dowel 46 is formed so that the fixing screw 34 (see FIG. 2) can be inserted. Specifically, the insertion hole 57 has a circular daruma hole 57A through which the fixing screw 34 can be inserted, and a long hole 57B that communicates with the daruma hole 57A and extends in the longitudinal direction of the instrument body 20.

  The fixed screw 34 is inserted into the daruma hole 57A, and the elongated hole 57B can be moved with respect to the inserted fixed screw 34. Thereby, the attachment position of the instrument main body 20 can be adjusted by moving the instrument main body 20 in the longitudinal direction. After adjusting the mounting position of the instrument body 20, the first outer dowel 46 is fixed to the downward surface 13 (see FIG. 2) by screwing the fixing screw 34 to the downward surface 13 of the construction material 12.

  As shown in FIG. 8, a pair of insertion holes 58 are formed in the top portion 47 </ b> A of the second outer dowel 47. The insertion hole 58 of the second outer dowel 47 is a long hole formed so that the fixing screw 34 (see FIG. 2) can be inserted and extending in a direction perpendicular to the longitudinal direction of the instrument body 20.

The fixing screw 34 is inserted into the insertion hole 58 of the second outer dowel 47, and the insertion hole 58 can be moved with respect to the inserted fixing screw 34.

Here, the projecting dimension L2 of the first outer dowel 46 and the second outer dowel 47 is formed to be smaller than the projecting dimension L1 of the pair of projecting portions 43. As a result, the instrument body 20 can be stably fixed to the downward surface 13 by bringing the pair of convex portions 43 into contact with the downward surface 13.

  Returning to FIG. 3, the third outer dowel 48 of the standing side surface 42 is formed in a similar shape to the first outer dowel 46, so detailed description thereof is omitted. Further, the fourth outer dowel 49 of the standing side surface 42 is formed in a similar shape to the second outer dowel 47, and therefore detailed description thereof is omitted.

As shown in FIGS. 2 and 4, the concave portion 44 of the upward side surface 41 is provided with a first inner dowel 52 and a second inner dowel 53. The first inner dowel 52 and the second inner dowel 53 protrude into the interior 51 of the instrument body 20, and the light source unit 24 (specifically, the lower case 32) is supported by the first inner dowel 52 and the second inner dowel 53. The An LED circuit board 25 of the light source unit 24 is provided on the lower case 32.
Therefore, the LED circuit board 25 can be supported in a state of being separated downward from the downward surface 13 (that is, in a floating state).

As a result, even when the flatness of the downward surface 13 of the building material 12 is low (that is, when it is undulating), the undulating shape of the downward surface 13 can be prevented from affecting the light source unit 24 and deformed into the LED circuit board 25. And cracking can be prevented.
Moreover, the heat dissipation of the LED circuit board 25 can also be obtained by supporting the LED circuit board 25 so as to be separated downward from the downward surface 13.

As shown in FIGS. 2 and 9, the light source 24 of the lower case 32 is covered with a translucent cover 26. The light source unit 24 includes an LED package 21 mounted on the LED circuit board 25, and an LED package cover 23 that covers the LED package 21 and is fixed to the lower case 32 (the instrument body 91).

Second locking portion (locking portion) 69.
Similarly to the first end cover 28, the second end cover 29 is attached to the second longitudinal end 20 </ b> B of the instrument body 20. As a result, the second longitudinal end 20B of the instrument body 20 and the second longitudinal end 26B of the translucent cover 26 are covered with the cover body 67 of the second end cover 29.

Thus, the translucent cover 26 can be attached to the instrument body 20 along the arrow A direction, and the first end cover 28 and the second end cover 29 can be attached along the arrow A direction.
Thereby, even if structures such as other standing walls and shelves are arranged on both ends in the longitudinal direction of the lighting fixture 10, the translucent cover 26, the first end cover 28, and the second end portion are provided on the fixture body 20. The cover 29 can be attached, and the installation of the lighting fixture 10 is not hindered.
