The cover member described in Patent Document 1 is a direction orthogonal to the longitudinal direction and the width direction of the instrument body in a state where the light source unit is accommodated in an accommodation recess provided on one surface of the instrument body formed in a long shape. In FIG. 2, each of the pair of extending portions overlaps with the opening edge of the receiving recess.
Therefore, when dust or the like accumulates in this gap after being used for a long period of time, the light flux in the lateral direction gradually decreases, and there is a problem in terms of optical characteristics and design properties.

Furthermore, the cover part described in Patent Document 1 is such that when the light source part is attached to the instrument body part by inserting a part on the opposite side to the irradiation side into the recess, there is no gap between the opening edge of the recess. It has an overlapping extension part.
For this reason, when removing a light source part from an instrument main-body part, there was no place for an operator to grasp a light source part, and it was difficult to work.

In the lighting fixture described in Patent Literature 2, the light source unit is attached to the fixture main body so that a gap is formed between the longitudinal side of the light source unit and the longitudinal side wall of the recess.
The light source part can be removed from the instrument main body part by inserting a dedicated jig into the gap, but it requires a lot of work because it requires a dedicated jig.
Further, when the light source part is attached to the instrument body, the light source part is pivotally attached by attaching the hook part of the locking wall to the hole and turning the hook part as a fulcrum. For this reason, the gaps on both sides formed between the light source part and the recesses along the longitudinal direction may cause unbalanced darkness when the light source part emits light, which is problematic in terms of design. .

  An object of this invention is to provide the light source unit which can position a light source unit in a suitable position with respect to an instrument main body, and an illuminating device.

The light source unit of the present invention is
In the light source unit attached to the longitudinally shaped instrument body,
The light source side mounting portion that is pulled in the direction of the device main body by an elastic force in a state of being connected to the device side mounting portion arranged in the device main body, and that determines the position of the device main body in the short direction ,

(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 two gaps between the light source unit 100 and the instrument main body 200 that are 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, since the angle around the longitudinal direction X is correctly determined, the gaps between the light source unit 100 and the instrument 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.

  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.

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.
