The power supply apparatus 250 has one end in the longitudinal direction X attached to the cut / drawn processing unit 401 and the other end attached to the drawing / processing unit 402.
The feature of the first embodiment is mainly the attachment structure of the power supply device 250 in the drawing unit 402.
First, a mounting structure in the drawing portion 402 will be described.

As shown in FIG. 8, the frame 220 that is the support member 930 has the arrangement surface 221 a on which the light emitting unit 210 that emits light is arranged, and the power supply device 250 that is the control device 910 that controls the light emitting unit 210. And a back surface 221b.
The frame 220 is formed with a drawing portion 402 that protrudes from the arrangement surface 221a toward the back surface 221b and has a flat portion 402a at the protruding top.
The drawing unit 402 is formed by drawing.
A screw 403 serving as an attachment mechanism 940 is disposed on the drawing unit 402 on the back surface 221b side with respect to the arrangement surface 221a, and the power device 250 is attached to the protruding portion 920 in a state where the power device 250 is in contact with the flat portion 402a. ing. That is, the screw 403 is a fixing tool for attaching the power supply device 250 to the frame 220.

  The drawing portion 402 is formed on the back surface 221b side with respect to the arrangement surface 221a.

A through hole 402b is formed in the flat portion 402a.
The power supply device 250 has a power supply main body 251 that is an outer portion 950 in which a through hole 253a is formed so as to overlap the through hole 402b of the flat portion 402a.
The screw 403 fixes the power supply device 250 to the flat portion 402a in a state where the screw 403 is inserted into the through hole 402b of the flat portion 402a and the through hole 253a of the power supply main body portion 251.

The drawing unit 402 is formed on the frame bottom 221 of the frame 220, but the drawing unit 402 is combined with a burring unit 253 formed on the power source main body 251.
The burring portion 253 is formed by burring, and a screw groove that is combined with the thread of the screw 403 is formed on the inner periphery of the through hole 253a of the burring portion 253.
As shown in FIG. 8B, a burring portion 253 is arranged on the flat portion 402a so that the through hole 402b and the through hole 253a communicate with each other, and a screw thread of the screw 403 is connected to the through hole 253a.

*** Effects of Embodiment 1 ***
Thus, by providing the drawing unit 402, the power supply device 250 can be fixed to the frame 220 using only the frame bottom 221.
Therefore, it is not necessary to make the dimension of the power supply device 250 in the short direction Y (FIG. 3) to reach each of the pair of frame side surfaces 222.
That is, the space of the length of each dimension W1 of FIG. 3 can be maintained.
Therefore, the improvement of the material cost of the material which comprises the power supply main-body part 251 which is an outer part of the power supply device 250 can be suppressed.

As shown in FIG. 8, by using the drawing unit 402, a space 404 is formed between the substrate 211 and the flat part 402 a of the drawing unit 402.
By housing the head 403 a of the screw 403 in the space 404, there is an effect that the substrate 211 that is subsequently attached to the arrangement surface 221 a does not interfere with the screw 403.

Also, as shown in FIGS. 10 and 11, the space 404 can be sealed by setting the diameter Y of the outer periphery of the drawn portion 402 smaller than the width X of the substrate 211.
Further, it is possible to prevent a metal piece (cutting piece) that may be generated when the screw 403 is tightened into the burring portion 253 formed in the power source main body 251 from entering the inside of the cover 230.

Further, when the power supply device 250 is fixed to the drawing unit 402 of the frame 220, the screw 403 advances in the upward direction Z1 while rotating spirally.
Therefore, since the tip of the screw 403 does not protrude to the arrangement surface 221a, the screw tip does not block the light emitted from the light emitting unit 210.
Therefore, the shadow of the screw tip is not projected onto the cover 230 during lighting, and the light emitted from the light emitting unit 210 is uniformly diffused by the cover 230.
That is, the designability during lighting of the light emitting unit 210 is improved.

In the first embodiment, one of the power supply devices 250 is inserted into the cut-drawing processing unit 401 and fixed.
However, the cut-drawing portion 401 may have the same shape of the drawing portion as the drawing portion 402, and the drawing portion may be fixed using screws in the same manner as the drawing portion 402.
In this case, a burring portion is formed in the power supply main body portion 251 so as to communicate with the through hole formed in the cut-drawing processing portion 401.

A screw 403 is used as the attachment mechanism 940 of the power supply device 250.
However, the attachment mechanism 940 is not limited to the screw 403, and a fixture such as an aluminum rivet or a resin snap-fit member may be used, or caulking may be performed by pressing metals together. The fixture used as the attachment mechanism 940 can be manufactured using a resin material, a ceramic material, or the like in addition to a metal material including iron, stainless steel, aluminum, or the like.

Further, the drawing portion 402 that creates the space 404 is excellent in workability as it is lower.
“The drawing portion 402 is low” means that the length of the upward Z1 from the arrangement surface 221a to the flat portion 402a is short.
When the drawing unit 402 is low, the overall height of the power supply device 250 attached to the frame 220 is not increased, and as a result, the overall height of the lighting fixture 1 can be suppressed from increasing.
Therefore, the head shape of the screw 403 for fixing the power supply device 250 is preferably a low-head screw with a short height.
The height of the drawn portion 402 is preferably 2 mm or less.

In the first embodiment, power supply device 250 is fixed using burring portion 253 formed so as to rise upward Z1 and screw 403.
However, the burring portion 253 may be a concave portion or a through hole in which a screw groove is not formed, and the power supply device 250 may be fixed using a screw 403 and a nut.

In Embodiment 1, the frame 220 is formed using a metal material.
However, the material used for the frame 220 is not limited to a metal material, and all or a part of the frame 220 may be formed using a resin material, a ceramic material, or a glass material.

The drawing portion 412 is formed on the back surface 271b side with respect to the arrangement surface 271a.

  In the second embodiment, the flat portion 412a is not formed with a through-hole for inserting or attaching a screw. In addition, no through hole is formed in the power supply main body 281 that is the outer portion 951 of the power supply device 280.

In the second embodiment, the flat part 412a and the power supply main body part 281 are joined by caulking. Specifically, as shown in FIG. 15C, for example, a draw lock caulking type caulking process can be used. FIG. 15C shows a caulking processing portion 415 that is formed by caulking so that the processing protrusion 416 fits inside the drawing portion 412 on the back surface 271b side with respect to the arrangement surface 271a. However, the present invention is not limited thereto, and the crimping processing portion 415 may have the processing protrusion 416 formed on the side opposite to the arrangement surface 271a from the power source main body 281.
For example, as shown in FIG. 15A, the crimping portion 415 is formed by a die that receives a punch protruding from the P direction from the D direction.

<Modification>
For the caulking process, other than the above-described draw lock caulking system, a processing system such as a cut lock caulking system or a spot caulking system can be used.

Embodiment 3 FIG.
With reference to FIG.17 and FIG.18, the attachment structure of the power supply device 300 which concerns on Embodiment 3 is demonstrated.
FIG. 17A shows a state before the power supply device 300 is cut and raised and engaged with the claw portion 422. FIG. 17B shows a state in which the power supply device 300 is cut and raised and is engaged with the claw portion 422, and FIG. 17C is an enlarged detailed view of the F portion in FIG. 17B. .
FIG. 18 is a perspective view illustrating attachment of the power supply device 300 to the cut-and-raised claw portion 422.
The feature of the third embodiment is the mounting structure of the power supply device 300 mainly in the cut and raised claw portion 422.

  As shown in FIGS. 17 and 18, the frame 290 is formed by cutting and raising a cut-and-raised claw portion 422 that is a protruding portion 920 protruding from the arrangement surface 291 a toward the back surface 291 b on the frame bottom portion 291. The cut-and-raised claw portion 422 is plate-like and has a thickness that allows deformation such as bending. The cut-and-raised claw portion 422 is formed closer to the back surface 291b than the arrangement surface 291a.

  The power supply device 300 includes a power supply main body 301 that is an outer portion 952 that is disposed at a position corresponding to the cut and raised claw portion 422 and has a through hole 303a into which the cut and raised claw portion 422 can be inserted. The cut-and-raised claw portion 422 is bent so as not to be removed from the through-hole 303a while being inserted into the through-hole 303a, so that the power supply device 300 is cut and raised and fixed to the claw-portion 422.

In the third embodiment, the power supply main body 301 that is the outer portion 952 of the frame 290 and the power supply device 300 is not formed with a through hole for inserting or attaching a screw.
On the other hand, a through hole is formed in the frame 290 by forming the cut and raised claw portion 422. Preferably, the through hole is closed by the substrate 211 arranged on the arrangement surface 271a.
As shown in FIG. 18A, bottom convex portions 292 a and 292 b are formed on the back surface 291 b of the frame 290. As shown in FIG. 17C, the top portion 292aa of the bottom convex portion 292a supports the power source main body 301. Although not shown, the top portion 292bb of the bottom convex portion 292b also supports the power source main body 301. Therefore, in a state in which the cut-and-raised claw portion 422 is bent and the power supply device 300 is cut and raised and engaged with the claw portion 422, the power supply device 300 is reliably supported by the bottom protrusions 292a and 292b.

<Modification>
The direction in which the frame bottom portion 291 is raised to form the claw portion 422 by cutting and raising the rear surface 291b from the arrangement surface 291a of the frame 290 is arbitrary.
The through-hole 303a formed in the power source main body 301 can be arbitrarily shaped and oriented as long as the cut-and-raised claw portion 422 can be inserted and is not removed in a state where the cut-and-raised claw portion 422 is bent. You can choose.
If the cut-and-raised claw 422 is not removed from the through-hole 303a while being inserted into the through-hole 303a, the bending direction and the bending angle can be arbitrarily selected.
The cut-and-raised claw portion 422 may be engaged with the through-hole 303a by other deformation such as twisting in addition to the bending deformation.

*** Effects of Embodiment 3 ***
The effects of the third embodiment will be described below.
(1) Since the power source main body 301 is attached to the frame 290 by the cut-and-raised claw portion 422 formed on the frame 290, a fixing tool such as a screw is not necessary. Therefore, the manufacturing time and manufacturing cost of parts can be reduced.
(2) The position where the power supply main body 301 is attached to the frame 290 can be determined by cutting and raising the claw portion 422 into the through hole 303a.
(3) Fixing strength can be obtained without using an attachment mechanism (fixing tool) such as a screw.
(4) By adopting a shape that ensures hermeticity, it is possible to prevent foreign matters such as insects and dust from entering the light source unit.
