The attachment stabilizing portion is configured by a first back wall 53 extending from a back side end of the first end walls 21 and 23 in a direction orthogonal to the first end walls 21 and 23. The first back wall 53 contacts the back wall 15 (for example, the inner surface) of the instrument main body member 31.
The first back wall 53 has attachment means for attaching the first end members 33, 35 to the instrument body member 31. Here, a screw member is used for attaching the first end members 33 and 35.
The instrument body member 31 has a screw hole 15 a for the first end members 33 and 35 at the longitudinal end of the back wall 15, and the first end members 33 and 35 are formed on the first back wall 53 in contact with the back wall 15. It has a through hole 55 for a screw member (see FIG. 6).

The first end members 33 and 35 have reinforcing portions for suppressing deformation of the instrument body member 31. The reinforcing portion is constituted by a pair of first side walls 57 extending in the direction perpendicular to the first end wall 51 from the end of the instrument main body member 31 in the first end walls 21 and 23 in the short direction. The first side wall 57 contacts the side walls 17 and 19 (for example, the inner surface) of the instrument main body member 31. The reinforcing portion has a function of improving workability when attaching the first end members 33 and 35 to the instrument body member 31.

The inner fitting portions of the first end members 33 and 35 are inserted into the end portions of the instrument main body member 31 so that the screw holes 15 a of the back wall 15 overlap.
Thereafter, the screw member is inserted from the inside through the through hole 55 of the first end member 33, 35 and screwed into the screw hole 15 a of the instrument body member 31.
Moreover, the part extended | stretched inside the 2nd extending parts 25b and 27b of the instrument main body member 31 to the small notch part 63 of the 1st front wall 59 of the 1st end members 33 and 35, and turned up Is brought into contact with or close to the back surface of the end portion 59a of the first front wall 59.
At this time, the first extending portions 25 a and 27 a of the instrument main body member 31 are supported by the end portions 59 a of the first front wall 59 of the first end members 33 and 35. For this reason, the second extending portions 25b and 27b can be easily bent.
As described above, the first end members 33 and 35 are fixed (attached) by screwing with the screw members and locking with the second extending portions 25b and 27b.
In a state where the first end members 33, 35 are attached to the instrument body member 31, between the first end walls 21, 23 of the first end members 33, 35 and the pair of side walls 17, 19 of the instrument body member 31, There are butted portions of the first end walls 21 and 23 and the side walls 17 and 19. The abutting portion exists on the side of the end walls 21 and 23 because the first end members 33 and 35 are fitted into the instrument main body member 31.

(1-3) 2nd end member It demonstrates using FIG. 9 mainly.
The second end members 37 and 39 cover at least the butted portions of the first end members 33 and 35 and the instrument main body member 31. The second end members 37 and 39 cover at least the first end walls 21 and 23 of the first end members 33 and 35 and the first front wall 59 including the chipped portions 61 and 63. Thereby, the chip | tip parts 61 and 63 of the 1st front wall 59 are hidden, and the design property can be improved.
The second end members 37, 39 are formed on the second end wall 71 that covers the first end walls 21, 23 of the first end members 33, 35, and the first front wall 59 when the chipped portions 61, 63 are not present. And a second front wall 73 covering all from the front side.
The second end members 37 and 39 are attached to the first end members 33 and 35 after the straight tube lamp 5 is attached to the instrument main body 11. The mounting of the second end members 37 and 39 is performed by a screw member. The second end members 37 and 39 have a through hole 71 a for a screw member in the center of the second end wall 71. In addition, the 1st end members 33 and 35 have the screw holes 21a and 23a in the 1st end walls 21 and 23, as shown in FIG.
The second end members 37 and 39 have a disengagement restricting means for restricting the second end members 37 and 39 from disengaging from the first end members 33 and 35. The disengagement restricting means is configured by a second extending portion 75 extending from the end of the second front wall 73 opposite to the second end wall 71 to the back side. Since the second extending portion 75 is locked to the first extending portion (locked portion) 65 of the first end members 33 and 35, the second extending portion 75 can be said to be a locking portion.

(2) Instrument side mounting tool It demonstrates mainly using FIG.
The appliance-side mounting tool 13 mounts the straight tube lamp 5 using the lamp-side mounting tool 223.
The mounting is performed using the restoring force of the spring body 81. That is, when the fixture-side mounting tool 13 mounts the lamp-side mounting tool 223, the spring body 81 is engaged with the lamp-side mounting tool 223 in a state of being elastically deformed so as to be separated from the back wall 15 of the fixture body 11. Then, the lamp-side mounting tool 223 approaches the back wall 15 of the instrument body 11 by the restoring force of the spring body 81. As a result, the straight tube lamp 5 is attached to the instrument 3.
The appliance-side mounting tool 13 includes a spring body 81 and a spring fixing member 83 for fixing the spring body 81 to the appliance main body 11.
The spring body 81 includes a pair of coil spring portions 85 and 87, a pair of extending wire portions 89 and 91 extending from one end of each coil spring portion 85 and 87, and the other end of each coil spring portion 85 and 87. And a U-shaped line portion 93 extending and connected to each other. The U-shaped line portion 93 is engaged with the lamp-side mounting tool 223.
The spring fixing member 83 includes a fixing portion 95 fixed to the back wall 15 and a coil fixing portion 97 for fixing the coil spring portions 85 and 87.

(3) Support member The description will be made mainly with reference to FIG.
The support member 20 is configured by bending a long rectangular plate made of metal or by injection molding a resin material. Here, the support member 20 is obtained by pressing one metal plate. Thereby, when the straight tube lamp 5 is mounted on the instrument main body 11, the support member 20 can be elastically deformed in a direction approaching the back wall 15 of the instrument main body 11.
The support member 20 connects the fixed portion 101 fixed to the back wall 15, the contact portion 103 that contacts the translucent cover body 209 in the straight tube lamp 5, and the contact portion 103 and the fixed portion 101. And a connecting portion 105.
The connection part 105 and the contact part 103 are on both sides of the fixing part 101 when viewed from the longitudinal direction of the instrument body member 31 and are paired with each other.
The support member 20 may include a return portion 107 that extends along the inner surfaces of the side walls 17 and 19 of the instrument body 11, for example, in addition to the fixing portion 101, the contact portion 103, and the connecting portion 105 described above.

(3-1) Fixing Part The fixing part 101 has a long rectangular shape, and is fixed so that the longitudinal direction of the rectangular shape is the short direction of the instrument main body member 31. For example, a screw member is used for fixing, and the screw member inserted through the through hole 15b of the back wall 15 of the instrument main body member 31 is screwed into the screw hole 111 in the central portion of the fixing portion 101.
The dimension in the longitudinal direction of the fixing portion 101 is substantially equal to the distance between the pair of side walls 17 and 19 of the instrument main body member 31. Thereby, even if it fixes the support member 20 to the instrument main body member 31 with one screw member, it can prevent that the support member 20 rotates.

(3-2) Connecting Part The connecting part 105 is inclined with respect to the fixed part 101 when viewed from the longitudinal direction of the instrument main body member 31. Here, as the connecting portion 105 moves away from the surface of the fixed portion 101 in a direction orthogonal to the surface (in other words, as it approaches the straight tube lamp 5), the interval between the pair of connecting portions 105 is reduced. It extends from each end in the longitudinal direction of the fixed part 101. That is, when viewed from the longitudinal direction of the instrument main body member 31, the instrument body member 31 is inclined so as to be narrowed with respect to the fixed portion 101. As a result, the contact portion 103 can be elastically deformed in a direction (front and back direction) away from the fixed portion 101.
As shown in FIG. 4, the ends of the pair of connecting portions 105 on the contact portion 103 side are close to the outside of the pair of ribs 295 in the translucent cover body 209 of the straight tube lamp 5. Thereby, the space in the instrument main body member 31 can be used effectively, and the illuminating device 1 can be reduced in size as a whole.
In the space formed between the connecting portion 105 and the fixed portion 101, a power cable and an external cable are arranged (not shown). Thereby, the space in the instrument main body member 31 can be used effectively, and the illuminating device 1 can be reduced in size as a whole.

(3-3) Abutting Part The abutting part 103 has a back surface abutting part 113 that abuts at least the surface of the straight tube lamp 5 on the back wall 15 side (the surface of the back wall 293a). The back surface abutting portion 113 abuts on an outer portion of the pair of ribs 295 in the translucent cover body 209 of the straight tube lamp 5 (see FIG. 4). The back contact portion 113 extends substantially parallel to the back wall 15 of the instrument body 11.
In addition to the back surface contact portion 113, the contact portion 103 includes side surface contact portions 115 that contact the surfaces of the both side walls 293 c of the translucent cover body 209 of the straight tube lamp 5. The side contact portion 115 contacts the surface adjacent to the back wall 293a among the side walls 293c of the straight tube lamp 5. The pair of side walls 293c of the straight tube lamp 5 is inclined so as to spread frontward, and the side contact portion 115 is also inclined so as to spread frontward. The side surface contact portion 115 can reduce the backlash of the straight tube lamp 5 in the short direction.

(3-4) Return portion The return portion 107 is provided with the straight tube lamp 5 from the end of the contact portion 103 having the back surface contact portion 113 and the side surface contact portion 115 opposite to the connecting portion 105. It is folded back to the opposite side and extends to the back side while abutting (approaching) the pair of side walls 17 and 19 of the instrument body member 31.
The folding is performed so as to have a flat portion 117 extending from the end of the contact portion 103 in a direction parallel to the front walls 25 and 27 of the instrument body 11. Even when the screw member fixing the support member 20 is detached and the support member 20 is about to fall from the instrument main body 11, the flat part 117 falls because the flat part 117 is supported by the front walls 25 and 27 of the instrument main body 11. Never do.
Since the end of the folded flat portion 117 opposite to the contact portion 103 is located in the vicinity of the side walls 17 and 19 of the instrument main body 11, the end portion between the side walls 17 and 19 of the instrument main body 11 and the support member 20 is located. It is possible to prevent the operator's fingers and the like from being caught.
The return portion 107 has an extending portion 119 extending along the side walls 17 and 19 of the instrument main body 11 from the end of the flat portion 117 opposite to the abutting portion 103.

The cylinder 203 has a rectangular portion 231 having a rectangular cross-sectional shape. The cylinder 203 has a pair of extending portions 233 and 235 in addition to the rectangular portion 231. The cylinder 203 is made of, for example, a metal material. Here, an extruded product is used. The cylinder 203 also has a heat sink function for releasing heat during light emission of the LED unit 205.

(1-1) Rectangular part The rectangular part 231 has a pair of long side walls 237 and 239 and a pair of short side walls 241 and 243. Long side walls 237 and 239 of the rectangular portion 231 are arranged in parallel with the back wall 15 of the instrument body 11. Of the pair of long side walls 237 and 239, the outer surface of one long side wall 239 located on the side far from the back wall 15 is a flat surface 245. Hereinafter, one long side wall 239 is referred to as a front side long side wall 239, and the other long side wall 237 is referred to as a back side long side wall 237.
The front long side wall 239 is recessed toward the back long side wall 237 in the cross section of the cylindrical body 203, and the bottom surface of the recessed portion 247 is a flat surface 245. In FIG. 16, the lead line of the recessed portion 247 is made an arrow to distinguish it from the flat surface 245.
The LED unit 205 is disposed on the flat surface 245. The rectangular portion 231 has projecting pieces 251 and 253 that project so as to close the recessed portion 247 from both sides of the recessed portion 247 in the cross section of the cylindrical body 203. The mounting substrate 271 of the LED unit 205 is inserted into the insertion grooves 255 and 257 formed by the recessed portion 247 and the overhanging pieces 251 and 253. Thereby, fall of LED unit 205 can be prevented.

As shown in FIGS. 12 to 14, the cylindrical portions 305 and 307 of the positioning members 211 and 213 are fitted to both ends in the longitudinal direction of the cylindrical body 203 so as to be in contact with both end surfaces of the cylindrical body 203. Thereby, the insertion grooves 255 and 257 of the cylindrical body 203 are closed by the positioning members 211 and 213, and the LED unit 205 can be fixed to the cylindrical body 203 without using a fixture for directly fixing the LED unit 205.
A power supply unit 207 is arranged inside the rectangular portion 231 as shown in FIG. The circuit board 281 of the power supply unit 207 has a long rectangular shape as shown in FIGS. The dimension of the circuit board 281 in the short direction is substantially equal to the distance between the pair of short side walls 241 and 243 of the cylindrical body 203. Thereby, the movement of the tube body 203 of the circuit board 281 in the short direction can be restricted without providing the position restricting means.

(1-2) Extending portion The pair of extending portions 233 and 235 are light from the corner portions 261 and 263 on both sides in the short direction of the front long side wall 239 (the side where the short side walls 241 and 234 are present) from the LED unit 205. The emission direction is extended so that the interval increases as the distance from the front long side wall 239 increases. That is, the pair of extending portions 233 and 235 extend in a front-side expanded shape.
The pair of extending portions 233 and 235 extend linearly in the cross-sectional shape and are inclined with respect to the flat surface 245 on which the LED unit 205 is disposed. Thereby, for example, even when water droplets or the like adhere to the front side of the extending portions 233 and 235, the water droplet does not flow to the LED unit 205 side.
When a reflection function is provided on the surfaces of the pair of extending portions 233 and 235, the extraction efficiency of light emitted from the LED unit 205 can be improved. The extending ends of the pair of extending portions 233 and 235 reach the vicinity of the inner surface of the translucent cover body 209 as shown in FIG. Thereby, it can prevent that the light radiate | emitted from LED unit 205 wraps around to the back side of extending | stretching part 233,235, and can improve the extraction efficiency of light.
The pair of extending portions 233 and 235 are at substantially the same positions (in the front and back directions) as the front walls 25 and 27 of the instrument 3 in the cross section in a state where the straight tube lamp 5 is mounted on the instrument 3 (see FIG. 4). ). Thereby, it can prevent that the light radiate | emitted from the LED unit 205 is interrupted | blocked by the instrument 3, and can improve the extraction efficiency of light.

(1-3) Others As shown in FIGS. 12 to 14, the cylindrical body 203 is attached to the translucent cover body 209 via positioning members 211 and 213 fitted to the inner periphery of the translucent cover body 209. It is done. The cylinder 203 has a connecting portion 265 that is connected to the positioning members 211 and 213. The connecting portion 265 is provided on the back side of the pair of extending portions 233 and 235. Here, it is provided on the back surfaces of the pair of extending portions 233 and 235. Thereby, the cylinder 203 and the positioning members 211 and 213 can be connected without causing a shadow or the like in the light emitted from the LED unit 205.
Here, the connecting portions 265 are provided at the corner portions 261 and 263 on both sides of the front long side wall 239 in the short direction and on the outer side from the center of the extending portions 233 and 235 in the short direction. Here, the total number of connecting portions 265 is four, but may be one, or may be five or more. For example, tapping screws are used to connect the cylindrical body 203 and the positioning members 211 and 213, and the connecting portion 265 is constituted by fixed grooves 267 and 269 extending in the longitudinal direction of the cylindrical body 203.

(2) LED unit A description will be given mainly with reference to FIG.
The LED unit 205 includes a mounting substrate 271 and a plurality of LEDs 273. The mounting substrate 271 has a rectangular shape, and is disposed on the flat surface 245 so that the longitudinal direction of the mounting substrate 271 and the longitudinal direction of the cylindrical body 203 coincide with each other. The plurality of LEDs 273 are provided at equal intervals in two rows along the longitudinal direction of the mounting substrate 272. The arrangement of the LEDs 273 is an example.
The LED unit 205 has connection terminals for connecting to an inner cable that is electrically connected to the power supply unit 207 on both ends of the mounting substrate 271 in the longitudinal direction and in the lateral direction. Specifically, a connector 275 for connecting to an adapter (not shown) provided at the end of the inner cable is provided.

(3) Power supply unit Description will be made mainly with reference to FIGS.
The power supply unit 207 receives power from a commercial power supply or the like and generates power to be supplied to the LED 273 of the LED unit 205. The power supply unit 207 mounts a plurality of electronic components 277 and 279 constituting a circuit 276 for generating power on a circuit board 281. The generated electric power is supplied to the LED unit 205 via an internal cable. The power supply unit 207 may include an insulating sheet 283 in addition to the electronic components 277 and 279 and the circuit board 281. In FIG. 18, the circuit 276 is illustrated as a box shape, and in FIG. 19, two electronic components are denoted by reference numerals for convenience.
The power supply unit 207 is arranged inside the rectangular portion 231 of the cylinder 203 as shown in FIG. The circuit board 281 has a long rectangular shape, and the longitudinal direction of the circuit board 281 coincides with the longitudinal direction of the cylinder 203 inside the cylinder 203. The circuit board 281 has a fixing hole 285 at one end in the longitudinal direction. The convex portion 343 of the positioning member 213 is inserted into the fixing hole 285 from the front side (lower side) and engaged (described later).

The dimension in the short direction of the circuit board 281 substantially matches the distance between the pair of short side walls 241 and 243 of the rectangular portion 231. Thereby, even if the circuit board 281 is fixed only at one end in the longitudinal direction, the backlash can be reduced. Since the illuminating device 1 is installed at the upper side and irradiates the lower side, the fixing of the power source unit 207 is ensured even if the power unit 207 is fixed simply by engaging the convex portion 343 of the positioning member 213 from below.
The circuit board 281 has a connection terminal for connecting to the inner cable at one end in the longitudinal direction. Specifically, a connector 287 for connecting to an adapter provided at the end of the inner cable is provided. The circuit board 281 is connected to the outer cable at the other end in the longitudinal direction. Here, the outer cable is directly connected to the circuit board 281 by solder.
As a result, the short dimension of the circuit board 281 can be reduced with respect to the circuit board having two connectors at one end, and connection errors can be reduced. In particular, since the straight tube lamp 5 has a long shape, it is possible to increase the length of the circuit board 281 by reducing the width of the circuit board 281 by providing one connector at the end in the longitudinal direction of the circuit board. , 279 can be secured.

The insulating sheet 283 covers the electronic components 277 and 279 and the circuit board 281. Here, the electronic components 277 and 279 and the circuit board 281 are surrounded so that the end portions 283a and 283b in the circumferential direction of the insulating sheet 283 are on the back side of the circuit board 281 when the circuit board 281 is viewed from the longitudinal direction thereof. (See FIG. 19A.) Thereby, even if a metal material is used for the cylinder 203, the insulation between the power supply unit 207 and the cylinder 203 is ensured.
The insulating sheet 283 is bent at four locations so that the cross section is a square, and has a thickness that spreads outward while maintaining this shape to some extent. The insulating sheet 283 has a fixing hole 289 at a position corresponding to the fixing hole 285 of the circuit board 281. The projection 203 343 of the positioning member 213 engages with the fixing hole 289 of the insulating sheet 283 and the fixing hole 285 of the circuit board 281, whereby the cylindrical body 203 is fixed in the insulating sheet 283 in the longitudinal direction. The fixing of the insulating sheet 283 in the circumferential direction of the cylindrical body 203 is performed by the insulating sheet 283 bent so as to have a quadrangular cross section coming into contact with the inner peripheral surface of the rectangular portion 231 to spread outward.
The insulating sheet 283 has a notch 291 for preventing interference with the protruding portion 347 of the positioning member 213 (see FIG. 22B and FIG. 23A).

(4) Translucent cover body It demonstrates using FIG.4 and FIG.20 mainly.
The translucent cover body 209 has a cylindrical shape and is made of a translucent resin material.
The translucent cover body 209 has a cover cylinder portion 293 that accommodates the cylinder body 203, the LED unit 205, the power supply unit 207, and the like. The translucent cover body 209 has one or more ribs 295 extending in the longitudinal direction of the cover tube portion 293. Thereby, the rigidity of the translucent cover body 209 can be improved.
The cover tube portion 293 has a cross-sectional shape similar to a trapezoidal shape. Of the pair of parallel sides (walls) 293a, 293b constituting the trapezoidal shape in the cross section, the side (wall) 293a having the short length faces the back wall 15 of the instrument body 11 when the instrument 3 is mounted. .
That is, of the pair of parallel sides (walls) 293a and 293b forming a trapezoidal shape in the cross section of the cover tube portion 293, the longer side (wall) 293b side is the light emitting surface of the straight tube lamp 5. . Thereby, the extending direction of the pair of extending portions 233 and 235 of the cylindrical body 203 is the same as the extending direction of the side wall 293c of the cover cylindrical portion 293, and the translucent cover body 209 can be reduced in size.

A long bottom (front wall) 293b located on the front side of the cover tube portion 293 has an arc shape in which the substantially center of the translucent cover body 209 in the short direction extends most in the cross section. The long side wall in the cross section is referred to as a back wall 293a, and the short side wall in the cross section is referred to as a front wall 293b.
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. The two ribs 295 are provided on the back surface of the cover cylinder portion 293. The two ribs 295 are orthogonal to the back surface of the cover tube portion 293 in the cross section. A lamp-side mounting tool 223 (described later) is attached between the two ribs 295.
A screw member is used for attaching the lamp-side mounting tool 223, and two ribs 295 are provided with through holes 297. Thereby, the lamp-side mounting tool 223 can be attached to the translucent cover body 209 without providing a through-hole that communicates with the cover tube portion 293.

Although the basic configuration of the positioning members 211 and 213 is the same, the outer cable is led out from the other 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 in the cylinder 203 is the one end described above, and the positioning member 213 disposed at the end is referred to as the non-hole positioning member 213. The positioning member 211 arranged at the other end is referred to as a perforated side positioning member 211.
The common configuration of the perforated side positioning member 211 and the non-porous side positioning member 213 will be described simply as the positioning members 211 and 213, and the individual configuration will be described by distinguishing the positioning members.

The plate-like portions 301 and 303 have outer peripheral surfaces that are in contact with part or all (here, all) of the inner peripheral surface of the translucent cover body 209. That is, the outer peripheral shape of the plate-like portions 301 and 303 is identical in design with the inner peripheral shape of the translucent cover body 209. Thereby, the backlash with respect to the translucent cover body 209 of the positioning members 211 and 213 can be reduced.
The outer peripheral portions of the plate-like portions 301 and 303 are flange portions 309 and 311 that project inward in the thickness direction of the plate-like portions 301 and 303. Thereby, the contact (contact) area of the outer peripheral surface of plate-shaped part 301,303 and the inner peripheral surface of the translucent cover body 209 can be increased, and the positioning members 211 and 213 of the translucent cover body 209 are increased. Can prevent falling inside. In particular, the flange 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. 14).

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. Here, four are provided. The pair of through holes 313 near the center is for a first screw member that joins the lid bodies 215, 217, the positioning members 211, 213, and the cylindrical body 203, and the through holes 313 serve as the first through holes 313. .

The cylindrical portions 305 and 307 are inserted into the rectangular portion 231 of the cylindrical body 203 (internally fitted to the rectangular portion 231). Thereby, the space | interval of the rectangular part 231 of the cylinder 203 and the translucent cover body 209 can be made small, and size reduction of the illuminating device 1 and the straight tube | pipe lamp 5 can be achieved as a whole.

Further, the cylindrical portions 305 and 307 are inserted into the rectangular portion 231 of the cylindrical body 203. For this reason, the cylindrical parts 305 and 307 and the rectangular part 231 can be fitted without blocking the light emitted from the LED 273.
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 rectangular portion 231 of the cylindrical body 203. Thereby, it can control that cylinder 203 rotates with the longitudinal direction as a rotation axis to positioning members 211 and 213. By providing the cylindrical portions 305 and 307 on the plate-like portions 301 and 303, the plate-like portions 301 and 303 can be reinforced, and the plate-like portions 301 and 303 can be thinned.
