(Variation 5)
The embedded illumination device may include a C-channel avoidance illumination device. For example, a dimension of about 220 mm can be adopted as the width of the illuminating device in which the height of the embedded instrument body is low and the width of the lighting device in the short direction.

As described above, the mounting structure between the light source unit 100 and the recess 211 is the same as the mounting structure described in the first embodiment.
In addition, although the light source unit, the fixture main body, and the lighting fixture described above are all examples of the longitudinal shape, the shape is not limited thereto, and may be other shapes such as a square, a circle, and a polygon.

<Plate spring 230>
FIG. 9 is a front view of the leaf spring 230. FIG. 10 is a perspective view of the leaf spring 230. In Embodiment 1, as will be described later with reference to FIGS. 15 and 16, the width dimension of the leaf spring 230 is the same dimension W3 throughout.

The leaf spring 230 is a longitudinal leaf spring formed of an elastic material such as a stainless steel material or a spring steel plate. The leaf spring 230 includes a first flat portion L1, a first bent portion M1, a second flat portion L2, a second bent portion M2, a third flat portion L3, a third bent portion M3, a fourth flat portion L4, and a fourth bent portion. A portion M4, an arc portion E, and a bent portion K are provided. The first flat portion L1 is a fixing portion 231 that is fixed to the bottom surface portion 211a of the recess 211. The arc-shaped portion 232 includes a first bent portion M1, a second flat portion L2, a second bent portion M2, a third flat portion L3, a third bent portion M3, a fourth flat portion L4, a fourth bent portion M4, and an arc portion. E. The bent part K is the tip part 233.
(1) The 1st flat part L1 goes to a longitudinal direction from one edge part of a longitudinal shape. The first flat portion L1 is fixed to the bottom surface portion 211a with a screw.
(2) The first bending portion M1 is formed with the first bending radius R1 at the end of the first flat portion L1. (3) The second flat portion L2 is bent at the first angle θ1 with the first bending radius R1 and rises from the first flat portion L1. The second flat portion L2 becomes a movable axis.
(4) The second bending portion M2 is formed at the end of the second flat portion L2 with the second bending radius R2 in the direction opposite to the first bending radius R1.
(5) The third flat portion L3 is bent and extended to the acute second angle θ2 with the second bending radius R2. (6) The third bending portion M3 is formed at the end of the third flat portion L3 with the third bending radius R3 in the direction opposite to the second bending radius R2. The third bending portion M3 controls the sliding of the arc portion E by hitting the plate portion 1501 of the connector 150 immediately before the light source unit 100 is completely attached to the instrument main body 200.
(7) The fourth flat portion L4 is bent and extended to the acute third angle θ3 with the third bending radius R3. (8) The fourth bending portion M4 is formed at the end of the fourth flat portion L4 with the fourth bending radius R4 in the direction opposite to the third bending radius R3.
(9) The arc portion E is bent into the obtuse fourth angle θ4 with the fourth bending radius R4, extends in the longitudinal direction toward the first flat portion L1, and is convex in the rising direction of the second flat portion L2. It is a part of. The arc portion E is a sliding portion that slides in contact with the upper side portion 152 a of the connector 150.
(10) The bent portion K is formed by bending the end of the arc portion E and is hooked on the upper side portion 152a of the connector 150.

  The second flat portion L2 serves as a movable shaft during the elastic action of the leaf spring 230 pulling the light source unit 100.

  The leaf spring 230 constitutes the tension mechanism 9010 of the lighting device 10 together with the coupler 150 of the light source unit 100. The pulling mechanism 9010 includes a leaf spring 230 disposed on the instrument body 200 and a connector 150 disposed on the light source unit 100 and pulling the light source unit 100 in the direction of the instrument body 200 by being coupled to the leaf spring 230. . The connector 150 has a plate portion 1501. The plate portion 1501 has a plate shape, is an opening 152 into which the plate spring 230 is inserted, and the plate spring 230 is attached at both ends 9152c of the edge 9152a with which the plate spring 230 abuts. A constraining opening 152 is formed.

  The number of leaf springs 230 can be changed according to the shape of the instrument body 200. When the length of the instrument body 200 in the longitudinal direction is short, a mechanism may be adopted in which the leaf spring 230 is installed only at one end in the longitudinal direction and the other end is fixed by a hook or the like. Moreover, when the length of the instrument body 200 in the longitudinal direction is long, the leaf springs 230 may be installed at both ends and the center in the longitudinal direction. When the leaf spring 230 is installed in the central portion, the plate spring 230 and the connector 150 included in the light source unit 100 corresponding to the leaf spring 230 are selected so as not to interfere with the power supply device 140 attached to the light source unit 100.

<Terminal block 240>
A power supply wire connected to an external power source is connected to the terminal block 240. Further, the terminal block 240 is connected to a feed wire for sending electric power and signals to the adjacent instrument body when the instrument body 200 is connected in the longitudinal direction. Therefore, a power supply wire and a feed wire are disposed in the recess 211.

<Attaching work of the light source unit 100>
Next, an operation of attaching the light source unit 100 to the instrument main body 200 attached in advance to the attachment unit 300 such as a ceiling will be described with reference to FIGS. FIG. 12 shows a state before the light source unit 100 is attached to the instrument main body 200. FIG. 13 is a diagram illustrating a process of attaching the light source unit 100 to the instrument main body 200. FIG. 14 shows a cross section after the light source unit 100 is attached to the instrument body 200. FIG. 14A is a cross section by a plane having the short direction Y as a normal direction, and FIG. 14B is a cross section by a plane having the long direction X as a normal direction. Here, the attachment to the attachment part 300 of the instrument main body 200 includes a method of fixing to the suspension bolt suspended from the ceiling, a method of fixing directly to the ceiling with a fixing tool such as a screw, and the like.
In FIG.
(A) shows the state before the light source unit 100 is attached to the instrument main body 200. FIG.
(B) shows the state in which the operator has connected the distal end portion 233 of the light source unit 100 to the connector 150 in a state where the leaf spring 230 is elastically deformed so that the curvature of the arc portion E of the leaf spring 230 is increased. .
(C) shows a state in which the back side Ea of the arc part E slides with respect to the upper side part 152a of the connector 150.
(D) shows a state in which the light source unit 100 is attached to the instrument main body 200.

(Fig. 13 (a))
13A, in the instrument main body 200, a fixing portion 231 of the leaf spring 230 is fixed to the bottom surface portion 211a with a screw. The light source unit 100 is not attached to the instrument body 200.

(Fig. 13 (b))
Next, in FIG. 13B, the leaf spring 230 is in a state of being elastically deformed with the second flat portion L2 as the center of rotation so that the arc portion E is in a substantially vertical state with respect to the bottom surface portion 211a.
An operator causes the leaf spring 230 to pass through the opening 152 from the distal end portion 233 of the leaf spring 230 with respect to both of the connectors 150. The operator hooks the tip end portion 233 of the leaf spring 230 on the upper side portion 152 a of the opening 152 of the connector 150 and suspends the light source unit 100 from the instrument main body 200. This state is a temporary attachment state of the light source unit 100. The two leaf springs 230 are disposed at both ends of the instrument body 200, and the light source unit 100 is suspended by the two leaf springs 230 while maintaining a posture in a substantially parallel state with respect to the instrument body 200.

(Fig. 13 (c))
Next, in FIG. 13C, when the operator grasps the cover side portion 131 and lifts the light source unit 100 to the attachment side (upward), the back surface Ea of the arc portion E of the leaf spring 230 becomes the upper side of the opening 152. It slides on the part 152a by the restoring force of the spring. The sliding action of the arc portion E of the leaf spring 230 is due to the fact that the leaf spring 230 tries to return to its original shape when the worker lifts the light source unit 100 to the attachment side (upward). Without worrying about the spring 230, the leaf spring 230 returns to its original shape while sliding relative to the connector 150.

(Fig. 13 (d))
Next, in FIG. 13D, when the operator pushes up the light source unit 100 into the concave portion 211 of the instrument main body 200, the upper end portion 151 of the connector 150 comes into contact with the bottom surface portion 211 a of the concave portion 211. At this time, the leaf spring 230 suppresses the sliding of the arc portion E immediately before the mounting of the light source unit 100 to the instrument body 200 is completed. Then, when the mounting of the light source unit 100 to the instrument main body 200 is completed, the arc portion E of the leaf spring 230 presses against the upper side portion 152a of the opening 152 with respect to the upper side portion 152a of the opening 152. Positioned.
At this time, the spring constant when the leaf spring 230 supports the upper side portion 152a at the inner portion is much larger than the spring constant when the light source unit 100 is supported by the tip portion 233 in FIG. This can be roughly estimated as a cantilever beam having the first flat portion L1 as a fixed end because the first flat portion L1 is fixed to the instrument body 200 in the leaf spring 230. In the leaf spring 230, the linear distance (span) between the first bent part M1 and the fourth bent part M4 that hardly elastically deforms is, for example, 1/5 of the distance (span) between the first bent part M1 and the tip part 233. About 1/6. In cantilever beams, the span affects the spring constant by the third power. That is, if the spring constant at the fourth bending portion M4 is 1/5, it is 125 times the spring constant at the tip 233, and if it is 1/6, it is 216 times the spring constant at the tip 233. For this reason, when the operator completes pushing up (pushing) of the light source unit 100 into the concave portion 211 of the instrument main body 200, the inner portion of the fourth bent portion M4 of the leaf spring 230 is the opening 152 formed in the connector 150. The upper side portion 152a can be supported. That is, the own weight of the light source unit 100 can be supported at the inside portion of the fourth bent portion M4.

<Removing work of the light source unit 100>
Next, an operation for removing the light source unit 100 from the instrument body 200 will be described. The operation of removing the light source unit 100 is the reverse procedure of the above-described installation operation.
(1) As shown in FIG. 13D, the operator grasps the cover side portion 131 from the state in which the light source unit 100 is attached to the instrument body 200, and keeps the light source unit 100 in a substantially horizontal state on the irradiation side. Pull down (down).
(2) The operator pulls down the light source unit 100 through FIG. 13C to the state of FIG. 13B, and removes the tip 233 of the leaf spring 230 from the opening 152 of the connector 150.
(3) The operator removes the light source unit 100 from the instrument body 200 by the above procedure.

  The connector 150 has an opening 152 in which the leaf spring 230 is hooked. The upper end of the connector 150 is formed with an upper end 151 that comes into contact with the bottom surface 211 a serving as the bottom of the recess 211 when the light source unit 100 is attached to the instrument main body 200.

<*** Explanation of action and effect ***>
Next, the effect of Embodiment 1 is demonstrated using FIG. 15, FIG. FIG. 15 is a diagram illustrating an engagement relationship between the leaf spring 230 and the connector 150. FIG. 16 is a diagram for supplementing FIG. In the first embodiment, the opening 152 has a trapezoidal shape with the length dimension W1 of the lower side part 152b and the length dimension W2 of the upper side part 152a.
The length relationship is
W1> W2
It is.
As shown in FIG. 15, the length dimension W2 of the upper side part 152a is shorter than the length dimension W1 of the lower side part 152b. In the first embodiment, the width dimension W3 of the leaf spring 230 is the same dimension from the distal end portion 233 to the fixed portion 231. As shown in FIG. 15, the width dimension W <b> 3 of the leaf spring 230 is substantially the same as the length dimension W <b> 2 of the upper side portion 152 a of the opening 152. FIG. 16 is a conceptual diagram for explaining the function and effect. As shown in FIG. 16, in a state where the light source unit 100 is mounted on the instrument main body 200, the back surface Ea of the arc portion E of the leaf spring 230 is in contact with the upper side portion 152a. In addition, the movement in the lateral direction Y is regulated on both sides in the width direction of the leaf spring 230 where the back surface Ea is in contact with the upper side portion 152a by a part of the side side portions 152c on both sides connected to the upper side portion 152a of the opening 152. The

<Positioning in the short direction>
For this reason, the light source unit 100 in which the connector 150 is disposed is positioned in the short direction Y with respect to the instrument main body 200 in which the leaf spring 230 is disposed. Therefore, the light source unit 100 can be attached to the instrument main body 200 in a state where the centers of the instrument main body 200 and the light source unit 100 in the short direction Y are matched. Further, when it is desired to match the optical axis of the light emitted from the light source unit 100 with the center of the instrument body 200 in the short direction, it can be easily matched. In addition, since the gaps between the light source unit 100 and the instrument main body 200 formed along the longitudinal direction X with the light source unit 100 interposed therebetween are substantially equal, the balance is maintained and the design is excellent.

<Determining the angle around the longitudinal direction X>
The light source unit 100 is attached to the instrument main body 200 by being strongly pulled up to the attachment side (upward) in a state where the inner portion of the leaf spring 230 is in close contact with the upper side portion 152a of the opening 152. That is, the bottom surface portion 211a of the instrument main body 200 to which the leaf spring 230 is attached and the power supply attachment surface portion 111b of the plate portion 110 to which the connector 150 is attached are parallel to each other in the insertion / extraction direction Z (FIG. 14). It will be the normal direction. For this reason, the light source unit 100 determines the attachment angle 601 (FIG. 14B) of the light source unit 100 around the X axis when the longitudinal direction X around the instrument body 200, that is, when the longitudinal direction X is regarded as the X axis. it can. Therefore, the light source unit 100 is not attached to the instrument main body 200 with respect to the longitudinal direction X, and the light emitted from the light source unit 100 can maintain a certain direction. In addition, when the angle around the longitudinal direction X is correctly determined, the gap between the light source unit 100 and the instrument main body 200 formed along the longitudinal direction X with the light source unit 100 interposed therebetween is substantially equal. The balance is maintained and the design is excellent.

  As described above, the connector 150 of the light source unit 100 and the leaf spring 230 of the instrument main body 200 constituting the pulling mechanism portion 9010 of the lighting device 10 are attached positions of the light source unit 100 with respect to the instrument main body 200 in the short direction Y. Also serves as a position determination mechanism for determining Further, the coupler 150 of the light source unit 100 and the leaf spring 230 of the fixture body 200 constituting the tension mechanism of the lighting device 10 determine an angle determination mechanism that determines the mounting angle of the light source unit 100 with respect to the longitudinal direction X of the fixture body 200. Doubles as

<*** Other configurations *****>
FIG. 17 is a diagram illustrating a first modification to FIG.
FIG. 18 is a diagram illustrating a second modification to FIG.
FIG. 19 is a diagram for explaining another modification of the first embodiment.

<Modification 1>
In FIG. 17, the opening 152 has a rectangular shape, that is, both the upper side portion 152a and the lower side portion 152b have the length dimension W1. Further, the leaf spring 230 has a shape in which the width dimension W4 of the tip end part 233 gradually increases to a width dimension W3 wider than the width dimension W4 as it goes to the fourth bending part M4. In other words, when viewed in the direction from the fourth bending portion M4 to the distal end portion 233, the leaf spring 230 has a tapered shape and the width gradually decreases toward the distal end portion 233. And the length dimension W1 of the upper side part 152a is substantially the same as the width dimension W3 of the leaf | plate spring 230, and when the light source unit 100 is attached to the instrument main body 200, the connection state of the connector 150 and the leaf | plate spring 230 is shown. Is the same as the state described in FIG. Therefore, also in the case of the modification 1, the effect similar to the case of FIG. 16 can be acquired.

<Modification 2>
In FIG. 18, the opening 152 has a trapezoidal shape, but the upper side 152a is longer than the lower side 152b.
That means
Length dimension W2> Length dimension W1
It is.
The leaf spring 230 has the same tapered shape as that of the first modification. The length dimension W2 of the upper side portion 152a is substantially the same as the width dimension W3 of the leaf spring 230, and when the light source unit 100 is attached to the instrument body 200, the coupling state between the coupling tool 150 and the leaf spring 230. Is the same as the state described in FIG. Therefore, also in the case of the modification 2, the same effect as the case of FIG. 16 can be obtained.

<Another modification>
FIG. 19 shows a modification in which the direction of the leaf spring 230 is reversed. That is, in FIG. 11, the two leaf springs 230 have the front end portions 233 facing in opposite directions in the longitudinal direction X.
On the other hand, in the case of FIG. 19, in the longitudinal direction X, the tip end portion 233 is disposed to face each other. The connector 150 is also arranged according to the direction of the leaf spring 230. Modification 3 can be combined with the configuration of FIG. 16, Modification 1 and Modification 2. In the case of Modification 3, the same state as described in FIG. 16 is obtained. Therefore, also in the case of the modification 3, the same effect as the case of FIG. 16 can be obtained.

Embodiment 2. FIG.

In the second embodiment, a sliding guide 211aa for guiding the sliding of the leaf spring 230 is arranged on the bottom surface portion 211a of the instrument main body 200. In addition to the connector 150 and the leaf spring 230, the sliding guide 211aa further shortens the length. This is a configuration that ensures position determination in the hand direction Y and angle determination around the longitudinal direction X.

  As shown in FIG. 20, the instrument main body 200 has the fixing portion 231 that is one end of the leaf spring 230 fixed thereto, and the leaf spring 230 is disposed. The instrument body 200 includes a sliding guide 211aa that is a leaf spring restricting portion 9211aa that restricts the movement of the tip end portion 233 that is the other end of the leaf spring 230. In FIG. 20, a pair of sliding guides 211aa is formed on the bottom surface portion 211a, and a gap W5 in the lateral direction Y is formed by the pair of sliding guides 211aa. The length of the gap W5 is substantially the same as the width dimension W4 of the tip 233.

As shown in FIG. 21, when the light source unit 100 is mounted on the instrument main body 200, the movement of the distal end portion 233 of the leaf spring 230 in the short direction Y is restricted by the gap W5.
Therefore, the state described in FIG. 16 can be further ensured by the pair of sliding guides 211aa.

As shown in FIGS. 22 and 23, the connector 150 includes a plate portion 1501 having a plate shape. The plate part 1501 is formed with an opening 152 into which the leaf spring 230 is inserted, and is connected to the instrument side fitting part 9212 formed in the instrument body 200 to be constrained by the instrument side fitting part 9212. It has an upper end 151 which is a joint portion 9151.

In the case of the first embodiment, the back surface Ea of the arc portion E of the leaf spring 230 hits the upper side portion 152a, and both sides in the width direction of the leaf spring 230 where the back surface Ea hits the upper side portion 152a It was necessary that the movement in the lateral direction Y be restricted by a part of the side portions 152c on both sides connected to the upper side portion 152a. However, in the case of the third embodiment, the leaf spring 230 and the connector 150 need only pull the connector 150 by the leaf spring 230. Of course, the movement restriction in the short direction Y described in the description of FIG. 16 may be added.

FIG. 24 shows a shape in which the upper end portion 151 and the instrument side fitting portion 9212 of the connector 150 are different from those in FIG.

In FIG. 24, the convex arc-shaped upper end portion 151 is fitted into the concave arc-shaped instrument side fitting portion 9212 so that the light source unit 100 is positioned in the short direction Y and the light source unit 100 is moved about the longitudinal direction X. Mounting angle can be determined.

Embodiment 4 FIG.
Embodiment 4 will be described with reference to FIGS. 25, 26, and 27 correspond to FIGS. 22, 23, and 24 of the third embodiment. The fourth embodiment is a case where the concavo-convex relationship between the instrument side fitting portion 9212 and the upper end portion 151 is opposite to that of the third embodiment. Even if the concavo-convex relationship is reversed, the same effect as in the third embodiment can be obtained.

In the first to fourth embodiments, the plate spring 230 is described as the instrument side mounting portion 9200, and the connector 150 is described as the light source side mounting portion 9100. However, in the first to fourth embodiments, the connector 150 may be used as the instrument-side mounting portion 9200, and the leaf spring 230 may be used as the light source-side mounting portion 9100. That is, a configuration in which the connector 150 is disposed in the instrument body 200 and the leaf spring 230 is disposed in the light source unit 100 may be employed.
In that case, the tension mechanism 9090 includes a leaf spring 230 disposed in the light source unit 100 and a connector 150 disposed in the instrument body 200. The connector 150 pulls the leaf spring 230 in the direction of the instrument body 200.

(Configuration of the flat portion 111)
The flat surface portion 111 is formed with a pair of protruding portions 114 protruding from the substrate mounting surface portion 111a toward the power supply mounting surface portion 111b, and a screw convex portion 115 having a screw through hole 115A. The screw convex part 115 is a convex part.

(Mounting condition)
As shown in FIG. 41, the protruding portion 114 penetrates the fixing hole 31b-3 and is caulked to fix the connector 1-2 to the flat portion 111. Further, as shown in FIG. 41, the screw 119 fixes the first fixing plate portion 20b to the screw projection 115.

  The connector 1-2 has the following features (1) to (5).

(Fixed in one place)
(1) The connector 1-2 can be fixed to the flat surface portion 111 by a fixing means arranged at one place. That is, in FIG. 38 and the like, the connector 1-2 is fixed to the flat surface portion 111 by the screw 119 and the protruding portion 114, but only the screw 119 is fixed to the flat surface portion 111 at one place. Also good.
As shown in FIG. 41, the connector 1-2 is fixed to the plate part 110 so as to sandwich the plate part 110 between the light emitting element substrate 120 and the connector 1-2. The screw 119 which is the first fixing part 641 fixes the connector 1-2 to the plate part 110 in a state of passing through the power supply mounting surface part 111b and the board mounting surface part 111a, and is connected only by the screw 119. The tool 1-2 may be fixed to the plate part 110. That is, the connector 1-2 may be fixed to the plate part 110 by the screw 119 that is one fixing part 630 arranged at one place without using the protruding part 114. The connector 1-2 is fixed to the plate part 110 by a screw 119 that is one fixing part 630 through a screw convex part 115 that is a convex part. In this case, there is an effect that the work process is reduced.
It should be noted that the aperture-shaped screw projection 115 is completely closed except for the through hole 115A. Therefore, when the light emitting element substrate 120 is bonded to the flat portion 111 with the adhesive member after the connector 1-2 is fixed to the plate portion 110 with the screw 119, the adhesive member is captured by the screw convex portion 115, and the flat portion 111. It will not leak out to the power supply mounting surface portion 111b side. Further, since the tip of the screw 119 is fixed by the adhesive member captured by the screw convex portion 115, the risk that the screw 119 is loosened or detached is reduced.

(No protrusion to the light-emitting element substrate side)
(2) Moreover, as shown in FIG. 41, regarding the fixing of the connector 1-2 to the flat portion 111, the light emitting element substrate 120 is located below the power supply mounting surface portion 111b, that is, from the substrate mounting surface portion 111a. There is nothing protruding to the side.
As shown in FIG. 41, the light emitting element substrate 120 is disposed on the substrate mounting surface portion 111a, and the screw 119 that is the first fixing portion 641 and the protruding portion 114 that is the second fixing portion 642 are the substrate mounting surface portion. In the direction from the power supply attachment surface portion 111b, which is the back surface of 111a, to the substrate attachment surface portion 111a, it does not protrude from the substrate attachment surface portion 111a.
Specifically, the screw 119 passes through a through-hole 115A formed so as to penetrate the substrate mounting surface portion 111a and the power supply mounting surface portion 111b, and the tip 119A is disposed at the position of the substrate mounting surface portion 111a or the substrate. The connector 1-2 is fixed to the plate part 110 in a state of being disposed closer to the power supply attachment surface part 111b than the position of the attachment surface part 111a. Therefore, there is an effect that the connector 1-2 can be freely arranged on the plane portion 111 regardless of the position of the light emitting element substrate 120.
As shown in FIGS. 38 and 41, the plate portion 110 has a shape that is recessed from the board attachment surface portion 111a toward the power supply attachment surface portion 111b and protrudes in a convex shape toward the power supply attachment surface portion 111b, and is formed with a through hole 115A. It has the convex part 115 for screws which is a shape part. Note that the through hole 115A is closed. As shown in FIG. 41, for example, the through hole 115A is closed by the shaft of the screw 119.

(Two types of fixing means)
(3) As described with reference to FIG. 38 and the like, the connector 1-2 is flattened by two types of fixing means, that is, the screw 119 that is the first fixing portion 641 and the protruding portion 114 that is the second fixing portion 642. It can be fixed to the part 111. Therefore, since a fixing means can be added according to the weight of the light source unit 100, there is an effect that it can be applied to various light source units 100.
As will be described later, the connector 1-2 is a component of the mounting device 600-3, but the connector 1-2 corresponds to the unit-side mounting portion 620. As described above, the connector 1-2, which is the unit-side mounting portion 620, is provided on the plate portion 110 by the first fixing portion 641 and the second fixing portion 642 of a different type from the first fixing portion 641. It has been fixed.

(Opening blockage)
(4) As shown in FIG. 41, the through-hole 115A of the screw projection 115 is closed with a screw 119. That is, since the opening formed with the attachment of the connector 1-2 to the flat portion 111 is blocked, there is an effect that dust and insects can be prevented from entering the cover 130 from the opening.

(Maintaining the light source unit posture)
(5) FIG. 42 is a diagram showing that the light source unit 100 is maintained in the state of FIG. The opening 15b-1 of the connector 1-2 can maintain the posture of the light source unit 100 with respect to the instrument body 200 in the state of FIG. That is, in the case of FIG. 42, the shape of the opening 15b-1 is such that the leaf spring 230 is hooked on the edge of the opening 15b-1. For this reason, in the case of FIG. 42, even if the operator removes his / her hand from the light source unit 100 in the state of FIG. 29A, the state of FIG. 29A is maintained. For this reason, since the one end of the light source unit 100 in the short direction is lowered, the operator can easily see the power supply mounting surface portion 111b on the side where the connector 1-2 is disposed. Therefore, there is an effect that the wiring work on the power supply attachment surface portion 111b side can be performed using both hands in a state where the power supply attachment surface portion 111b is easy to see.

  The connector 1-2 is a component of the attachment device 600-3. Regarding the connector 1-2, the connector 1-2 corresponds to the unit-side mounting portion 620, and the instrument-side mounting portion 610 corresponds to the leaf spring 230.

The second fixed plate portion 30c is connected to the first fixed plate portion 20c by the connecting portion 22c, and a screw receiving hole 31c-2 is formed.

(Configuration of the flat portion 111)
The flat surface portion 111 is formed with a pair of upright portions 116 cut and raised in the direction from the substrate mounting surface portion 111a to the power supply mounting surface portion 111b, and a screw convex portion 115 having a screw through hole 115A.

(Mounting condition)
As shown in FIG. 46, the screw 119 fixes the second fixing plate portion 30 c to the screw projection 115. Further, the insertion portion 21c-4 is inserted between the pair of upright portions 116. As shown in FIGS. 43 and 46, the distal end of the insertion portion 21c-4 protrudes from the standing portion 116.

  The connector 1-3 has the following features (1) to (5).

(Fixed in one place)

That is, in FIG. 43 and the like, the connector 1-3 is fixed to the flat surface portion 111 by the screw 119 and the insertion portion 21c-4, but only the screw 119 is connected to the flat surface portion 111 at one place. It may be fixed to. In this case, there is an effect that the work process is reduced.

(No protrusion to the light emitting element substrate side)
(2) Further, as shown in FIG. 46, with respect to the connection 1-3 being fixed to the flat surface portion 111, the light emitting element substrate 120 side is located below the power supply mounting surface portion 111b, that is, from the substrate mounting surface portion 111a. There is nothing to stick out. Therefore, there is an effect that the connector 1-3 can be freely arranged on the flat surface 111 regardless of the position of the light emitting element substrate 120.

(Two types of fixing means)
(3) As described with reference to FIG. 43 and the like, the connector 1-3 can be fixed to the flat surface portion 111 by two types of fixing means, that is, the screw 119 and the insertion portion 21c-4. Therefore, since a fixing means can be added according to the weight of the light source unit 100, there is an effect that it can be applied to various light source units 100.
The insertion part 21c-4 and the pair of upright parts 116 constitute a slide structure. The slide structure has a function of restricting movement with respect to a direction intersecting the slide direction, that is, a direction orthogonal to the direction in which the insertion portion 21c-4 is inserted. The slide structure is fixed so that movement in a specific direction can be restricted. As an effect of the slide structure, it is possible to prevent the light source unit from falling off by adding a support for the slide structure even when structural fatigue occurs in the fixing means for screw fixing or caulking after using the lighting device 10 for a long period of time. .

(Opening blockage)
(4) Further, as shown in FIG. 46, the through-hole 115 </ b> A of the screw convex portion 115 is closed with a screw 119. Furthermore, the opening 118 that has been formed as the upright portion 116 is formed is blocked by the insertion portion 21c-4. That is, the opening formed with the attachment of the coupler 1-3 to the flat surface portion 111 is closed, so that there is an effect that dust and insects can be prevented from entering the cover 130 from the opening.

(Maintaining the light source unit posture)
(5) Moreover, the opening 15c-1 of the coupler 1-3 has the same shape as the opening 15b-1 of the coupler 1-2, and the coupler 1-3 is also formed by the edge of the opening 15c-1. 100 postures can be maintained in the state of FIG.

Therefore, there exists an effect which can fix the connector 1-4 to the plane part 111 with a simple structure.
Note that the opening 117 </ b> C (FIG. 47) formed in the plane portion 111 by the formation of the bridge portion 117 is located on the center line 111 d (FIG. 4) in the longitudinal direction X of the plane portion 111. The center line 111 d is a reference line that passes through the center of the planar portion 111 in the short direction Y. The light emitting element substrate 120 is disposed on the center line 111d. Therefore, even if the opening 117C is not blocked with a tape, the opening 117C can be completely blocked by attaching the light emitting element substrate 120 to the substrate mounting surface portion 111a.

(Does not protrude toward the light-emitting element substrate)
(2) Also, as shown in FIG. 50, regarding the fixing of the connector 1-4 to the flat surface portion 111, the light emitting element substrate 120 is located below the power supply mounting surface portion 111b, that is, from the substrate mounting surface portion 111a.

(No protrusion to the light emitting element substrate side)
(2) Further, as shown in FIG. 54, regarding the fixing of the connector 1-5 to the flat surface portion 111, the light emitting element substrate 120 is lower than the power supply mounting surface portion 111b, that is, the substrate mounting surface portion 111a. There is nothing protruding to the side. Therefore, there is an effect that the connector 1-5 can be freely arranged on the plane portion 111 regardless of the position of the light emitting element substrate 120.

(Two types of fixing means)
(3) As described with reference to FIG. 51 and the like, the connector 1-5 can be fixed to the flat surface portion 111 by two types of fixing means, that is, the screw 119 and the insertion portion 31e-4. Therefore, since a fixing means can be added according to the weight of the light source unit 100, there is an effect that it can be applied to various light source units 100.

(Opening blockage)
(4) Further, as shown in FIGS. 51 and 54, the through hole 115 </ b> A of the screw convex portion 115 is closed with a screw 119. Further, the opening 118 that is formed along with the formation of the upright portion 116 is also closed by the insertion portion 31e-4.
