Japanese Unexamined Patent Publication No. 2014-078511 Japanese Unexamined Patent Publication No. 2012-003993

The cover member described in Patent Document 1 has a direction orthogonal to the longitudinal direction and the width direction of the instrument body when the light source unit is accommodated in the accommodating recess provided on one surface of the instrument body formed in a long shape. Each of the pair of extending portions overlaps with the opening edge of the accommodating recess so as not to occur.
Therefore, when dust or the like accumulates in this gap due to long-term use, the luminous flux in the lateral direction gradually decreases, which poses a problem in terms of optical characteristics and design.

Further, the cover portion described in Patent Document 1 is provided so that there is no gap with the opening edge of the recess when the light source portion is attached to the instrument main body by inserting a part of the side opposite to the irradiation side into the recess. It has overlapping extension parts.
For this reason, when the light source portion is removed from the instrument main body portion, there is no place for the operator to grasp the light source portion, which makes the work difficult.

In the lighting fixture described in Patent Document 2, the light source portion is attached to the fixture main body portion so that a gap is formed between the longitudinal side side of the light source portion and the longitudinal side wall portion of the recess.
The light source unit can be removed from the main body of the instrument by inserting a special jig into this gap, but the work is troublesome because a special jig is required.
Further, when the light source portion is attached to the main body of the fixture, the hook portion of the locking wall is hooked on the hole, and the light source portion is rotated and attached with the hook portion as a fulcrum. For this reason, the gaps on both sides formed between the light source portion and the recess along the longitudinal direction may cause unbalanced darkness when the light source portion emits light, which poses a problem in terms of design. ..

An object of the present invention is to provide a light source unit and a lighting device capable of positioning a light source unit at an appropriate position with respect to an instrument body.

The lighting device of the present invention
It is a long lighting device
With a long light source unit

(D) shows a state in which the light source unit 100 is attached to the instrument main body 200.

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

(Fig. 13 (b))
Next, in FIG. 13B, the leaf spring 230 is elastically deformed so that the arc portion E is substantially perpendicular to the bottom surface portion 211a with the second flat portion L2 as the center of rotation.
The operator passes the leaf spring 230 through the opening 152 through the tip 233 of the leaf spring 230 for both connectors 150. The operator hooks the tip portion 233 of the leaf spring 230 on the upper side portion 152a 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 mounting state of the light source unit 100. The two leaf springs 230 are arranged at both ends of the fixture body 200, and the light source unit 100 is suspended by the two leaf springs 230 while maintaining a posture substantially parallel to the fixture body 200.

(Fig. 13 (c))
Next, in FIG. 13C, when the operator grabs the cover side portion 131 and lifts the light source unit 100 to the mounting 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 portion 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 when the operator lifts the light source unit 100 to the mounting side (upward), the leaf spring 230 tries to return to its original shape by itself. The leaf spring 230 returns to its original shape while sliding with respect to the connector 150 without worrying about the spring 230.

(Fig. 13 (d))
Next, in FIG. 13D, when the operator pushes up the light source unit 100 into the recess 211 of the instrument body 200, the upper end 151 of the connector 150 comes into contact with the bottom surface 211a of the recess 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 on the fixture body 200 is completed. Then, when the mounting of the light source unit 100 on the instrument body 200 is completed, the arc portion E of the leaf spring 230 presses against the upper side portion 152a of the opening 152 of the connector 150 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 tip portion 233 supports the light source unit 100 in FIG. 13B. 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 main body 200 in the leaf spring 230. In the leaf spring 230, the linear distance (span) between the first bent portion M1 and the fourth bent portion M4, which is hardly elastically deformed, is, for example, 1/5 of the distance (span) between the first bent portion M1 and the tip portion 233. It is about 1/6. For cantilever beams, the span affects the spring constant by the cube. That is, the spring constant at the fourth bent portion M4 is 125 times the spring constant at the tip portion 233 if it is 1/5, and 216 times the spring constant at the tip portion 233 if it is 1/6. Therefore, when the operator completes pushing (pushing) the light source unit 100 into the recess 211 of the instrument body 200, the inner portion of the fourth bent portion M4 of the leaf spring 230 is formed in the connector 150 with the opening 152. The upper side portion 152a can be supported. That is, the weight of the light source unit 100 can be supported at the inner portion of the fourth bent portion M4.

<Removal work of light source unit 100>
Next, the work of removing the light source unit 100 from the instrument main body 200 will be described. The work of removing the light source unit 100 is the reverse procedure of the above-mentioned mounting work.
(1) As shown in FIG. 13D, the operator grasps the cover side 131 from the state where the light source unit 100 is attached to the instrument main 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. 13 (c) to the state shown in FIG. 13 (b), and removes the tip portion 233 of the leaf spring 230 from the opening 152 of the connector 150.
(3) In the above procedure, the operator removes the light source unit 100 from the instrument main body 200.

The connector 150 is formed with an opening 152 into which the leaf spring 230 is hooked. The upper end of the connector 150 is formed with an upper end portion 151 that abuts on the bottom surface portion 211a that is the bottom of the recess 211 when the light source unit 100 is attached to the instrument body 200.

<*** Explanation of action and effect ***>
Next, the effects of the first embodiment will be described with reference to FIGS. 15 and 16. FIG. 15 is a diagram showing 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 having a length dimension W1 of the lower side portion 152b and a length dimension W2 of the upper side portion 152a.
The length relationship is
W1> W2
Is.
As shown in FIG. 15, the length dimension W2 of the upper side portion 152a is shorter than the length dimension W1 of the lower side portion 152b. Then, in the first embodiment, the width dimension W3 of the leaf spring 230 is the same dimension from the tip portion 233 to the fixed portion 231. As shown in FIG. 15, the width dimension W3 of the leaf spring 230 is substantially the same as the length dimension W2 of the upper side portion 152a of the opening 152. FIG. 16 is a conceptual diagram for explaining the action and effect. As shown in FIG. 16, when the light source unit 100 is attached to the instrument main body 200, the back surface Ea of the arc portion E of the leaf spring 230 hits the upper side portion 152a. Further, on both sides of the leaf spring 230 in the width direction where the back surface Ea is in contact with the upper side portion 152a, the movement in the lateral direction Y is restricted by a part of the side side portions 152c on both sides connected to the upper side portion 152a of the opening 152. To.

<Positioning in the short direction>
Therefore, the light source unit 100 in which the connector 150 is arranged is positioned in the lateral direction Y with respect to the instrument main body 200 in which the leaf spring 230 is arranged. Therefore, the light source unit 100 can be mounted on the fixture body 200 with the centers of the fixture body 200 and the light source unit 100 aligned in the lateral direction Y. Further, when it is desired to align the optical axis of the light emitted from the light source unit 100 with the center of the instrument main body 200 in the lateral direction, it can be easily aligned. Further, since the gaps between the light source unit 100 and the instrument main body 200, which are formed along the longitudinal direction X with the light source unit 100 in between, are substantially the same distance, the balance is maintained and the design is excellent.

<Determining the angle around the longitudinal direction X>
The light source unit 100 is mounted on the instrument main body 200 by being strongly pulled up to the mounting 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 appliance 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 and have an insertion / removal direction Z (FIG. 14). It will be in the normal direction. Therefore, the light source unit 100 can determine the mounting angle 601 (FIG. 14 (b)) of the light source unit 100 around the X-axis when the longitudinal direction X with respect to the fixture main body 200, that is, 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 at an angle with respect to the longitudinal direction X, and the light emitted from the light source unit 100 can maintain a constant direction. Further, by correctly determining the angle around the longitudinal direction X, the gaps between the light source unit 100 and the instrument main body 200, which are formed along the longitudinal direction X with the light source unit 100 in between, are substantially the same. , Because the balance is maintained, it is also excellent in design.

As described above, the connector 150 of the light source unit 100 and the leaf spring 230 of the fixture main body 200, which constitute the tension mechanism portion 9010 of the lighting device 10, are the mounting positions of the light source unit 100 with respect to the fixture main body 200 in the lateral direction Y. Also serves as a position determination mechanism for determining. Further, the connector 150 of the light source unit 100 and the leaf spring 230 of the fixture main body 200, which constitute the tension mechanism of the lighting device 10, are angle determining mechanisms for determining the mounting angle of the light source unit 100 with respect to the longitudinal direction X of the fixture main body 200. Also serves as.

<Modification example 1>
In FIG. 17, the opening 152 is rectangular, 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 portion 233 gradually increases to the width dimension W3 wider than the width dimension W4 toward the fourth bent portion M4. That is, when viewed in the direction from the fourth bent portion M4 to the tip portion 233, the taper-shaped leaf spring 230 gradually narrows in width toward the tip portion 233. The length dimension W1 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 main body 200, the connecting tool 150 and the leaf spring 230 are connected.

The modified example 3 can be combined with the configuration of FIG. 16, each of the modified example 1 and the modified example 2. In the case of the modified example 3, the same state as described in FIG. 16 is obtained. Therefore, in the case of the modified example 3, the same effect as in the case of FIG. 16 can be obtained.

FIG. 20 is a perspective view showing the sliding guide 211aa. 21A and 21B are cross-sectional views for explaining the sliding guide 211aa, where FIG. 21A is a longitudinal sectional view and FIG. 21B is a sectional view in the lateral direction. 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, and in addition to the connector 150 and the leaf spring 230, the sliding guide 211aa is further shortened. The configuration ensures that the position of the hand direction Y and the angle around the longitudinal direction X are determined.

As shown in FIG. 20, in the appliance main body 200, the fixing portion 231 which is one end of the leaf spring 230 is fixed and the leaf spring 230 is arranged. The instrument body 200 includes a sliding guide 211aa, which is a leaf spring regulating portion 9211aa that regulates the movement of the tip portion 233, which is the other end of the leaf spring 230. In FIG. 20, a pair of sliding guides 211aa are 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 portion 233.

As shown in FIG. 21, when the light source unit 100 is attached to the instrument main body 200, the tip portion 233 of the leaf spring 230 is restrained from moving in the lateral direction Y by the gap W5.
Therefore, the state described in FIG. 16 can be further ensured by the pair of sliding guides 211aa.

Embodiment 3.
The third embodiment will be described with reference to FIGS. 22 to 24. In the third embodiment, the tension mechanism portion 9010 including the leaf spring 230 and the connector 150 further has an instrument-side fitting portion 9212. In the third embodiment, the tension mechanism portion 9010 is formed by fitting the upper end portion 151, which is the connecting side fitting portion 9151 of the connector 150, and the appliance side fitting portion 9212 formed on the instrument body 200. Similar to the first embodiment, it has the functions of positioning in the lateral direction Y and determining the angle around the longitudinal direction X.

FIG. 22 shows the connector 150 and the instrument-side fitting portion 9212 of the tension mechanism portion 9010 according to the first embodiment. As shown in FIG. 22, two instrument-side fitting portions 9212 are arranged on the bottom surface portion 211a of the instrument main body 200. The fixture-side fitting portion 9212 is formed by cutting a part of the bottom surface portion 211a in the upward direction Z from the light source unit 100 toward the fixture main body 200 in the insertion / removal direction Z. 23 (a) and 23 (b) are a cross-sectional view showing a state in which the light source unit 100 is attached to the instrument main body 200, and a diagram showing a connector 150, respectively. The cross-sectional shape of the instrument-side fitting portion 9212 is triangular.

In the third embodiment, the fixture-side mounting portion 9200 is a leaf spring 230, and the light source-side mounting portion 9100 is a connector 150 that connects to the leaf spring 230. As shown in FIGS. 22 and 23, the connector 150 includes a plate portion 1501 having a plate shape. The plate portion 1501 has an opening 152 into which the leaf spring 230 is inserted, and is bound to the instrument side fitting portion 9212 by fitting into the instrument side fitting portion 9212 formed in the instrument body 200. It has an upper end portion 151 which is a joint portion 9151.

As shown in FIGS. 22 and 23, the tension mechanism portion 9010 is arranged in the instrument main body 200, and the instrument side fitting portion 9212 that restrains the upper end portion 151 by fitting into the upper end portion 151 which is the connecting side fitting portion 9151. Have.

<*** Explanation of effect ***>

That is, the fixture-side fitting portion 9212 can be fitted into the upper end portion 151 to determine the positioning of the light source unit 100 in the lateral direction Y and the mounting angle of the light source unit 100 around the longitudinal direction X. 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 of the leaf spring 230 in the width direction where the back surface Ea hits the upper side portion 152a have openings 152. It was necessary that the movement in the lateral direction Y was 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 relationship between the leaf spring 230 and the connector 150 is such that the leaf spring 230 only needs to pull the connector 150. It goes without saying that the movement restriction in the lateral direction Y described in the explanation of FIG. 16 may be added.

FIG. 24 shows a shape in which the upper end portion 151 of the connector 150 and the instrument-side fitting portion 9212 are different from those in FIG. 22. FIG. 24A is a cross-sectional view showing a state in which the light source unit 100 is attached to the instrument main body 200. The cross-sectional shape of the fitting portion 9212 on the instrument side is a concave arc shape.
FIG. 24B shows a connector 150 in which the upper end portion 151 has a convex arc shape. In FIG. 24, the convex arc-shaped upper end portion 151 fits into the concave arc-shaped instrument-side fitting portion 9212 to position the light source unit 100 in the lateral direction Y and around the longitudinal direction X of the light source unit 100. The mounting angle can be determined.

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

In the first to fourth embodiments, the leaf spring 230 is described as the fixture 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 fixture-side mounting portion 9200, and the leaf spring 230 may be used as the light source-side mounting portion 9100. That is, the connector 150 may be arranged on the instrument main body 200, and the leaf spring 230 may be arranged on the light source unit 100.
In that case, the tension mechanism portion 9010 includes a leaf spring 230 arranged in the light source unit 100 and a connector 150 arranged in the instrument main body 200. The connector 150 pulls the leaf spring 230 in the direction of the instrument body 200.

The tension mechanism portion 9010 composed of the leaf spring 230 and the connecting tool 150 is arranged in the light source unit 100, and is fitted in the upper end portion 151 which is the connecting side fitting portion 9151 to restrain the upper end portion 151. It has 9112. Here, the light source side fitting portion 9112 corresponds to the fixture side fitting portion 9212 shown in FIGS. 22 and 25 formed on the flat surface portion 111 of the plate portion 110 of the light source unit 100. Similar to the case of the instrument-side fitting portion 9212, the uneven relationship with the upper end portion 151 may be such that the upper end portion 151 has a convex shape or a concave shape.

Therefore, it is possible to prevent a wiring defect in which the power supply electric wire and the feed electric wire are sandwiched between the light source unit 100 and the instrument main body 200, and a connection defect of these electric wires.

<Modification example>
Another example of the fifth embodiment will be described with reference to FIG. The description of the same configuration as that of the first to fourth embodiments will be omitted.
As shown in FIG. 30, in the connector 150 in another example, inclined side portions 152e are formed on both side portions of the upper side portion 152a forming the opening 152. The central side of the inclined side portion 152e is connected to the upper side portion 152a, and the outside of the inclined side portion 152e is connected to the side side portion 152c. In FIG. 30, the inclined side portion 152e and the side side portion 152c are connected via an arc-shaped connecting side portion 152ce, but the present invention is not limited to this form, and the inclined side portion 152e and the side side portion are not limited to this form. The 152c may be directly connected to the 152c without the arc-shaped connecting side portion 152ce.

<*** Explanation of effect ***>
In the case of FIG. 30, when the light source unit 100 is attached to the instrument main body 200, wiring work and wiring confirmation work are performed. At this time, the light source unit 100 is suspended from the fixture body 200 by the leaf spring 230 of the fixture body 200 being hooked on the connector 150 of the light source unit 100. As shown in the elliptical range of the broken line in FIG. 30, when the light source unit 100 is rotated in any rotation direction about the longitudinal direction, the light source unit 100 rotates at an angle at which the leaf spring 230 abuts on the inclined side portion 152e. It is regulated and the posture of the light source unit 100 is maintained at the angle. That is, when the worker performs the wiring work or the wiring confirmation work, the wiring portion of the light source unit 100 can be held in a state of facing the worker side, so that the worker can surely perform the wiring work and the wiring confirmation work.

Therefore, it is possible to prevent wiring defects in which the power supply electric wires and feed electric wires are sandwiched between the light source unit 100 and the instrument main body 200, and connection defects in these electric wires.

Embodiment 6.
The sixth embodiment will be described with reference to FIGS. 31 and 32. In the sixth embodiment, the configurations different from those of the first to fifth embodiments will be mainly described, and the description of the same configurations as those of the first to fifth embodiments will be omitted. FIG. 31 is a diagram illustrating the connector 150 according to the fifth embodiment. FIG. 32 is a diagram illustrating the operation and effect of the light source unit 100 using the connector 150 according to the fifth embodiment.

As shown in the square range of FIGS. 31A and 31C, the connector 150 of the sixth embodiment has a different shape of the upper end portion 151a. The upper end portion 151a of the connector 150 of the sixth embodiment has an arc-shaped outer shape as a whole at a portion facing the bottom surface portion 211a. In a state where the light source unit 100 is attached to the instrument main body 200, the upper end portion 151a is separated from the bottom surface portion 211a except for the central portion 701 in the lateral direction Y. The distance between the upper end portion 151a and the bottom surface portion 211a gradually increases toward the outside in the lateral direction Y. That is, the distance between the upper end portion 151a and the bottom surface portion 211a is gradually increasing. The outer shape of the upper end portion 151a may be a shape other than an arc shape, or the outer shape may be formed by a plurality of straight lines or a shape composed of a straight line and a curved line.
