The cover cylinder part 293 has a trapezoidal cross-sectional shape. Of the pair of parallel sides (walls) 293a and 293b constituting the trapezoidal shape in the cross section, the side (wall) 293a having a short side faces the back wall 15 of the appliance body 11 when mounted on the lighting fixture 3 Do. Among the walls constituting the trapezoidal shape, the wall close to the back wall 15 of the instrument body 11 is taken as the back wall 293a, the wall far from the back wall 15 is taken as the front wall 293b, and the side walls are taken as side walls 293c, 293d.
The front wall 293b of the cover cylindrical portion 293 has an arc shape in which the approximate center of the light-transmissive cover body 209 in the short direction projects most in cross section.

  There are two ribs 295, and the ribs 295 extend along the longitudinal direction of the cover tube portion 293 in parallel with each other. Two ribs 295 are provided on the back surface of the cover cylinder 293. The two ribs 295, 295 extend in a cross section orthogonal to the back surface of the cover cylindrical portion 293, and then form an inverted L shape toward the other ribs 295, 295. That is, the ribs 295 and 295 have a vertical portion 295a standing from the cover tube portion 293 and a horizontal portion 295b extending from the standing tip of the vertical portion 295a in the short direction.

Although the basic configuration of the positioning members 211 and 213 is the same, the outer cable is led out from one end of the cylinder 203 and the inner cable is introduced and led out from one end of the cylinder 203. There are different parts in the configuration of the positioning members 211 and 213.

Here, the end close to the power supply unit 207 housed inside the cylindrical body 203 is the one end described above, and the positioning member 211 disposed at the end is the perforated positioning member 211. The positioning member 213 disposed at the other end is referred to as a non-porous positioning member 213.
The common configuration of the perforated positioning member 211 and the non-porous positioning member 213 will be described simply as the positioning members 211 and 213, and the individual configurations will be described by distinguishing the positioning members.

(5-1) Common Configuration The positioning members 211 and 213 include plate-like portions 301 and 303 and a cylindrical portion provided on one surface of the plate-like portions 301 and 303 (of the “fitting portion” of the present invention. This corresponds to an example.) 305, 307. The positioning members 211 and 213 have extending portions 309 and 311 extending inward in the thickness direction of the plate-like portions 301 and 303 on the outer peripheral portions of the plate-like portions 301 and 303. In the plate-like portions 301 and 303, the side on which the cylindrical body 203 is present is referred to as the inside, and the side on which the lids 215 and 217 are present is referred to as the outside.

(Plate-like part)
The plate-like portions 301 and 303 have an outer peripheral surface that abuts on a part or all (here, all) of the inner peripheral surface of the translucent cover body 209. The plate-like portions 301 and 303 have through holes 313 and 315 through which screw members for coupling with the cylindrical body 203 are inserted. Four are provided here. The pair of through holes 313 and 313 existing near the center are for the first screw member 314 that couples the lids 215 and 217, the positioning members 211 and 213, and the cylinder 203, and the through holes 313 are used as the first through holes. It is assumed that 313. The other pair of through holes 315, 315 which exist outside the pair of first through holes 313, 313 are for the second screw member 316 which connects the positioning members 211, 213 and the cylindrical body 203, The second through hole 315 is used.
The plate-like portions 301 and 303 have reinforcing ribs 302 and 304. The reinforcing ribs 302 and 304 are provided on the surface (the inner surface) of the plate-like portions 301 and 303 located on the side of the cylindrical body 203.

(Tubular part)
The cylindrical portions 305 and 307 fit with the cylindrical portion 231 of the cylindrical body 203. The cylindrical portions 305 and 307 are inserted into the inside of the cylindrical portion 231 of the cylindrical body 203 (they are fitted into the cylindrical portion 231). The cross-sectional shapes of the cylindrical portions 305 and 307 are rectangular, and the outer peripheral surfaces of the cylindrical portions 305 and 307 are in contact with (or close to) the inner peripheral surface of the cylindrical portion 231 of the cylindrical body 203.

(Stretch section)
The extending portions 309 and 311 are provided along the inner peripheral surface of the cover cylindrical portion 293 of the translucent cover body 209.
The extending | stretching part 309,311 is provided over the perimeter of the outer periphery of the plate-like part 301,303, as shown to FIGS. 18-20. The extending portions 309 and 311 have two regions having different extending lengths (the dimensions in the direction (longitudinal direction) in which the central axis of the cover tube portion 293 extends). That is, the stretched portions 309 and 311 have short stretched portions 309a and 311a having short stretch lengths and long stretched portions 309b and 311b having stretch lengths longer than the short stretched portions 309a and 311a.

When viewed from a direction corresponding to the width direction of the translucent cover 209 (corresponding to (a) in FIG. 19), the elongated portions 309 b and 311 b are positioned on the front side relative to the cylindrical portions 305 and 307. It is provided in the back side half ranging from the site to the back side. In addition, the site | part located in the front side of the cylindrical parts 305 and 307 is equivalent to the position vicinity of LED273 of the LED module 205. FIG. Thereby, it can prevent that the light emitted from LED273 is interrupted | blocked by the long extending | stretching parts 309b and 311b.
The lengths of the long extension portions 309b and 311b (the dimensions in the direction parallel to the longitudinal direction of the cover tube portion 293) are longer than the length that can prevent the positioning members 211 and 213 from falling in the cover tube portion 293. Is preferred. That is, the distance between the fulcrum when the positioning members 211 and 213 are inclined in the translucent cover body 209 and the extended ends of the long extended portions 309b and 311b (the ends opposite to the plate-like portions 301 and 303). However, it is preferable that the distance is larger than the distance between the fulcrum and the inner peripheral surface of the translucent cover body 209 (the part facing the extension end).

  Since the positioning members 211 and 213 have the elongated portions 309 b and 311 b having the above lengths, the contact (contact) area between the outer peripheral surface of the plate-like portions 301 and 303 and the inner peripheral surface of the translucent cover body 209 is increased. The positioning members 211 and 213 can be prevented from falling inside the translucent cover body 209. In particular, the extending portions 309 and 311 protrude inward from the surface (inner surface) located inside the plate-like portions 301 and 303, and the outer surfaces of the plate-like portions 301 and 303 are flush with each other. Thereby, the adhesiveness with the lids 215 and 217, the inner packing 221, and the positioning members 211 and 213 can be improved (see FIG. 13).

The plate-like portion 301 of the perforated side positioning member 211 has one through hole 319, 321 in each of the region surrounded by the inner peripheral surface of the tubular portion 305 and the outer region of the region. The through-hole 319 provided in the region surrounded by the inner peripheral surface of the cylindrical portion 305 is referred to as an in-region through-hole 319, and the through-hole provided in the outer region of the region surrounded by the inner peripheral surface of the cylindrical portion 305 Let 321 be an out-of-region through hole 321.
The inner cable electrically connecting the power supply unit 207 and the LED module 205 is pulled out from the in-region through hole 319 to the outside of the perforated positioning member 211 when the power supply unit 207 is referenced, and then the out-of-region through hole 321 is returned to the inside of the perforated side positioning member 211.
An outer cable that electrically connects the power supply unit 207 and the commercial power supply side power cable enters the inside of the perforated positioning member 211 through the in-region through hole 319, and extends from the chipped portion 305 a of the cylindrical portion 305 to the cylindrical body 203. It is introduced inside.

(5-3) Non-Porous-Side Positioning Member This will be described mainly with reference to FIG.
Unlike the perforated positioning member 211, the plate-like portion 303 of the non-porous positioning member 213 does not pass the outer cable and the inner cable, and therefore the through holes 319 and 321 like the perforated positioning member 211 and the chipped portion 305a. I do not have
