A terminal block 25 is attached to the base plate 22, and the front end portion of the power supply wire 26 wired inside the wall or along the wall surface 11 is drawn out and connected to the front surface 221 side through the through hole 223. . The socket 23 is provided at the left and right end portions of the front surface 221 of the base plate 22 so that the lamp 21 is mounted on the center side. The socket 23 is electrically connected to the terminal block 25 by a wiring 27 and receives supply of electric power for lighting the lamp 21.

  As shown also in FIG. 3 and FIG. 4, tongue pieces protruding from the base plate 22 are perpendicular to the wall surface 11 (on the right side in FIG. And a pair of upper and lower brackets 24a and 24b are projected. Both brackets 24 a and 24 b are provided at right angles to the wall surface 11, and the upper and lower surfaces, which are the attachment surfaces 242 to which the shade 30 is attached, are horizontal. A screw hole 241 for attaching the shade 30 is provided in the center of each bracket 24a, 24b.

  The shade 30 is vertically divided into two and has an upper shade 31 and a lower shade 32. Each of the shades 31 and 32 has, for example, a semi-cylindrical shape, and has a louver 35 at an outer end of the outer peripheral wall 34 (an upper end portion in the upper shade 31 and a lower end portion in the lower shade 32). Is open. The shades 31 and 32 are detachably attached to the brackets 24a and 24b with screws 33 as fasteners.

  As shown in FIG. 3, a planar attachment portion 36 is provided at the wall 11 side end of the louver 35 that is the base end of the shade 30. The mounting portion 36 has a concave portion 361 having a size and shape into which the brackets 24a and 24b are fitted on the inner surface side, and a through hole 362 through which the screw 33 passes. As shown in FIG. 4, in the state where the upper and lower shades 31 and 32 are attached to the instrument body 20, the lower surface, which is the inner side surface 363 of the attachment portion 36, contacts the upper surface of the bracket 24 a in the upper shade 31. The upper surface, which is the inner surface 363 of the mounting portion 36, contacts the lower surface of the bracket 24b.

  In addition, as shown in FIG. 5, the inner side surface 363 of the mounting portion 36 (that is, the surface that contacts the brackets 24 a and 24 b in the mounted state) with the shades 31 and 32 held horizontally is in relation to the horizontal plane HP. The tip side is inclined in the opening direction. That is, in the upper shade 31, the lower surface (363) of the mounting portion 36 is inclined in the direction in which the tip side rises with respect to the horizontal plane HP, and in the lower shade 32, the upper surface (363) of the mounting portion 36 is lowered with respect to the horizontal plane HP. It is inclined in the direction to do.

As shown in FIG. 6, a frame portion 37 is provided along the inner end of the outer peripheral wall 34. The frame portion 37 has a planar inner surface 371, and a plurality of protrusions 372 are provided on at least one inner surface 371 of the upper shade 31 and the lower shade 32. Here, a case where two protrusions 372 are provided on both the upper shade 31 and the lower shade 32 is illustrated. The protrusions 372 provided on each of the shades 31 and 32 are arranged so as to be alternately positioned at predetermined intervals when attached. As shown in FIGS. 3 and 4, the most proximal side (wall surface 11 side) projection 372a of the projections 372 is provided closer to the wall surface 11 than the position of the screw hole 241 of the bracket 24a (24b).
In addition, as for each shade 31, 32, it is desirable to integrally mold the outer peripheral wall 34 (including the frame portion 37 and the protrusion 372) and the louver 35 with milky white acrylic.

  Therefore, as shown in FIG. 3, the upper shade 31 is attached to the instrument body 20 by fitting the bracket 24a into the recess 361 of the attachment portion 36 from above the bracket 24a and inserting the screw 33 into the through hole 362 from above. Then, it is screwed into the screw hole 241 of the bracket 24a and tightened. The lower shade 32 is attached to the instrument body 20 by fitting the bracket 24b from the lower side of the bracket 24b into the concave portion 361 of the attachment portion 36 and inserting the screw 33 into the through hole 362 from below. Screw into the hole 241 and tighten.

  At this time, the mounting surfaces 242 of the brackets 24a and 24b are provided horizontally, and the inner side surface 363 of the mounting portion 36 of each of the shades 31 and 32 is inclined outward from the horizontal plane HP. As a result, a force for moving the front end portions of the shades 31 and 32 toward the center acts (arrows A and B in FIG. 4). That is, in the upper shade 31, the front end portion is lowered, and in the lower shade 32, the front end portion is raised, so that the frame portions 37 of both the shades 31 and 32 are pressed against each other.

  Further, as the screw 33 is tightened, the most proximal projection 372a of one of the upper and lower shades 31 (32) comes into contact with the frame portion 37 of the other shade 32 (31) to serve as a fulcrum, and is more distal than the projection 372a. Since the screw 33 located in the position serves as a power point and the tip portion serves as an action point, the shades 31 and 32 are pressed against each other.

  As described above, according to the luminaire 10 according to the embodiment of the present invention described above, when the base ends of the pair of shades 31 and 32 are attached to the front surface 221 of the base plate 22 attached to the wall surface 11 with the screws 33, Since the tips of the shades 31 and 32 are pressed against each other, it is possible to prevent the front ends of the shades 31 and 32 that are divided into two vertically from falling down to make the gap uniform and improve the appearance.

In addition, since a plurality of protrusions 372 that contact the tip of the other shade 32 (31) are provided at the tip of at least one of the pair of shades 31 and 32, both the shades 31 and 32 are provided. The gap between the frame portions 37, which are the butted portions of 31 and 32, can be made constant at the height of the protrusion 372.
Further, by changing the height of the protrusion 372, the gap between the frame portions 37 can be changed as required.
