You can do it like this.

In addition, when the spring extension portion 161 of the instrument side spring 160 comes into contact with the side surface portion 112 or the power supply device 120, a reaction force is generated against the force with which the light source unit 200 is pushed in. The two plate portions 223 can be sandwiched between them. By bringing the spring extension portion 161 into contact with the side surface portion 112 or the power supply device 120, the frame 220 can be held without increasing the rigidity of the spring itself.

The instrument-side spring 160 does not need to be firmly attached to the convex portion 114, for example, by fixing it with a fixing device such as a screw. In the case of the instrument side spring 160, the end portion is fitted in the longitudinal direction (X-axis direction) into the spring attachment portion 115, which is a partially cut out portion of the convex portion 114, inside the convex portion 114.

The instrument-side spring 160 is more easily elastically deformed than the spring 250. In the lighting device 1, the fixture-side spring 160 is more elastically deformable than the spring 250, so that when the operator pushes the light source unit 200 into the lighting fixture 100, the light source unit 200 can be easily attached to the lighting fixture 100.

A process for attaching the light source unit 200 to the lighting fixture 100 using the fixture-side spring 1160 will be described with reference to FIGS. 40 and 41.

The operator first installs the fixture-side spring 1160 inside the fixture body 110 of the lighting fixture 100. The operator slides the spring engaging portion 1161c onto the convex portion 114 and inserts the instrument-side spring 1160 into the instrument main body 110. At this time, the spring extension part 1161 is elastically deformed inward in the lateral direction (Y-axis direction) of the lighting fixture 100 and is pushed in until the spring engagement part 1161c passes through the convex part 114. In the instrument side spring 1160, when the spring engaging portion 1161c passes the convex portion 114, the elastic deformation of the spring extension portion 1161 is released and the spring engaging portion 1161c is caught on the convex portion 114. In this state, the instrument side spring 1160 is attached to the protrusion 114 so as to cover the main body opening 113 of the instrument main body 110.

In order to further ensure the engagement between the spring engaging part 1161c and the convex part 114, a part of the convex part 114 is cut out as a first cutout part 114b shown in FIG. A missing spring attachment portion 115 may be formed. The spring engaging portion 1161c may be engaged with the spring mounting portion 115. When the instrument-side spring 1160 is installed in the instrument main body 110, the spring engaging portion 1161c of the instrument-side spring 1160 is inserted into the spring attachment portion 115, and the spring connecting portion 1160b faces the power supply device 120. are placed in contact with each other.

When attaching the light source unit 200 to the lighting fixture 100, the operator brings the end of the second plate part 223 of the frame 220 into contact with the spring diaphragm part 1160a1 of the fixture-side spring 160. The operator pushes the light source unit 200 into the instrument main body 110 with the end of the second plate portion 223 of the frame 220 in contact with the spring aperture portion 1160a1. Then, the end of the second plate portion 223 of the frame 220 slides on the spring constriction portion 1160a1 along the slope of the spring constriction portion 1160a1. At this time, the spring arm portion 1162 is elastically deformed outward in the lateral direction (Y-axis direction) of the lighting fixture 100, and the first plate portion 221 is pushed in until it comes into contact with the upper end of the convex portion 114. That is, when the light source unit 200 is attached to the lighting fixture 100, the second plate portion 223 contacts the spring diaphragm portion 1160a1, and the spring arm portion 1162 is elastically deformed in the lateral direction (Y-axis direction) of the lighting fixture 100. do. Thereafter, in the light source unit 200, the end of the second plate part 223 finishes sliding on the spring aperture part 1160a1, the elastic deformation of the spring arm part 1162 is released, and the second plate part 223 moves to the end of the spring arm part 1162. It is caught and held. The instrument side spring 1160 holds the second plate part 223 of the frame 220 so as to sandwich the second plate part 223 therebetween. The spring arm portion 1162 can hold the light source unit 200 by bringing the tip of the spring arm portion 1162 into contact with the second plate portion 223 of the frame 220 . Therefore, in the instrument side spring 1160, the spring engaging portions 1161c that are the ends engage with the convex portions 114 of the two side portions 112, respectively. Further, in the instrument side spring 1160, a central portion 165 located between the spring engaging portions 1161c, which are both ends, is constituted by a spring arm portion 1162, and the spring arm portion 1162 is connected to the second plate portion 222 of the light source unit 200. engage with.

It does not come off due to contact. In the appliance side spring 1160, when the spring extension portion 1161 comes into contact with the side surface portion 112 or the power supply device 120, a reaction force against the force of pushing the light source unit 200 is generated, and the second plate of the frame 220 is caused by the spring constriction portion 1160a1. The portion 223 can be sandwiched. By bringing the spring extension portion 1161 into contact with the side surface portion 112 or the power supply device 120, the frame 220 can be held without increasing the rigidity of the spring itself.

Note that the instrument-side spring 1160 does not need to be firmly attached to the convex portion 114, for example, by fixing it with a fixing device such as a screw. In the instrument-side spring 1160, at the spring mounting portion 115, which is a partially cut-out portion of the convex portion 114, the wall forming the convex portion 114 is inserted into the groove portion 1161c3 of the spring engaging portion 1161c. Further, the appliance-side spring 1160 is arranged such that the spring connecting portion 1160b faces the power supply device 120 and the power supply device 120 comes into contact with it. Therefore, the instrument-side spring 1160 is attached so as to be sandwiched between the convex portion 114 and the power supply device 120.

[Function of mounting base 400]
In the mounting base 400, a control section A 412 and a control section B 422 are slidably connected by a shaft section 430. The mounting base 400 has a control hole portion 412b that is a first engagement portion of the A portion formed in the control portion A 412, and a control convex portion 422b that is a second engagement portion of the B portion formed in the control B portion 422. When engaged, the lighting fixture 100 is rotatably held. In the mounting base 400, the inclination angle of the mounting portion 420 with respect to the pedestal portion 410 is determined by fitting the control convex portion 422b into any one of the plurality of control holes 412b. As shown in FIGS. 44 and 45, the control convex portion 422b fits into the control hole portion 412b while sliding the control portion A 412 of the pedestal portion 410, and holds the mounting portion 420 at a predetermined angle with respect to the pedestal portion 410. can be held in As shown in FIG. 44, the mounting base 400 has a leg portion 411 that is longer than the width direction (Y-axis direction) of the lighting device 1.

As shown in FIG. 44, when the control convex portion 422b is engaged with the control hole portion 412b formed at the position closest to the leg portion 411, the leg portion 411 and the mounting plate portion 421 are arranged substantially parallel to each other.

As shown in FIG. 45, as the mounting part 420 rotates with respect to the pedestal part 410 and the control convex part 422b is engaged with the control hole part 412b formed at a position away from the leg part 411, The plate portion 421 is arranged so as to have a large inclination with respect to the leg portion 411. Therefore, as the control convex portion 422b is engaged with the control hole portion 412b formed at a position distant from the leg portion 411, the angle between the lighting device 1 and the mounted portion 500 such as the ceiling or wall increases. It is rotated horizontally to make it smaller. Here, it is assumed that the lighting fixture 100 is attached to the mounting base 400 and is tilted parallel to the attached part 500. At this time, at least a part of the projection part 100d formed by projecting the lighting fixture 100 and the light source unit 200 onto the mounting part 500 in the direction perpendicular to the mounting part 500 is projected onto the leg part 411 in the lateral direction of the lighting fixture 100. It will be located outside of one end.

It should be noted that the structure of the unevenness formed on the A section first engagement section of the control section A 412 and the B section second engagement section of the control section B 422 may be other configurations. For example, one control hole portion 412b may be formed in the control portion A 412, and a plurality of control convex portions 422b may be formed in the control portion B 422. Alternatively, one control convex portion 422b may be formed in the control portion A 412, and a plurality of control hole portions 412b may be formed in the control portion B 422. Alternatively, the control section A 412 may be formed with a plurality of control protrusions 422b, and the control section B 422 may be formed with one control hole section 412b.

[Function and effect of frame 220]
The effect of the lighting device 1 according to the embodiment, which is the reduction in thickness of the lighting device 1 due to the frame 220, will be described below. In the light source unit 200, the frame 220 connects the first plate part 221 to which the light emitting module 210 is attached, the second plate part 223 facing the first plate part 221, and the first plate part 221 and the second plate part 223. Rigidity can be ensured by having the pillar portion 222 that is Therefore, the light source unit 200 can be made thinner without increasing the size in the vertical direction (Z-axis direction). As a result, the lighting device 1 including the light source unit 200 can be made thinner in the vertical direction (Z-axis direction).

Moreover, the lighting device 1 can effectively utilize the internal space of the fixture main body 110 by making the light source unit 200 thinner. Specifically, by making the light source unit 200 thinner, the light source unit 200 can be attached to the lighting fixture 100 without interfering with components housed in the fixture body 110, such as the power supply device 120. In addition, since the light source unit 200 is made thinner, the appliance main body 110 can separate an area in which the light source unit 200 is accommodated and an area in which the power supply device 120 and the like are accommodated in the vertical direction (Z-axis direction). can. The lighting device 1 can move the power supply device 120 to one side in the transverse direction (Y-axis direction) by dividing the interior of the fixture main body 110 into upper and lower parts. Therefore, the lighting device 1 can provide a housing location for the electric wire inside the device in the lateral direction (Y-axis direction) of the device main body 110, and it is possible to suppress enlargement of the lighting device 1. In addition, the lighting device 1 can prevent the wires from being caught between the light source unit 200 and the power supply device 120 by accommodating the wires in the device in the lateral direction (Y-axis direction) of the device body 110. can. With these configurations, the lighting device 1 can be downsized.

[Function and effect of spring 250]
In the illumination device 1, a spring 250 fixed to the light source unit 200 is formed at a spring bottom part 252b formed in a flat plate shape and at both ends of the spring bottom part 252b. It has a spring claw portion 252a that is elastically deformed. The spring 250 also has a spring engaging portion 252c formed at the tip of the spring claw portion 252a. The distance L1 between the closest portions of the two corresponding convex portions 114 is smaller than the distance between the farthest portions of the two opposing spring engaging portions 252c in the natural length of the spring claw portions 252a. Therefore, by pushing the light source unit 200 into the lighting fixture 100 using the elastic deformation of the spring 250, the operator can engage the light source unit 200 with the convex portion 114 of the fixture body 110 via the spring 250. can. Furthermore, by pulling out the light source unit 200 from the lighting fixture 100, the operator can remove the light source unit 200 from the lighting fixture 100 using the elastic deformation of the spring 250. As a result, in the lighting device 1, the light source unit 200 can be easily attached to and removed from the lighting fixture 100.

In the spring 250, when the light source unit 200 is attached to the lighting fixture 100, the spring engaging portion 252c engages with the convex portion 114. Therefore, in the lighting device 1, there is no need to provide a separate member for engaging with the spring 250 in the device main body 110 of the lighting device 100, and the number of members can be reduced. Therefore, the lighting device 1 can reduce the number of components housed in the fixture main body 110 and effectively utilize the internal space.

The spring engaging portion 252c of the spring 250 has an arcuate portion that faces the side surface portion 112 when the light source unit 200 is attached to the lighting fixture 100. Therefore, when an operator removes the light source unit 200 from the lighting fixture 100, the light source unit 200 can be easily removed from the lighting fixture 100 without a special jig that facilitates attachment and detachment of the light source unit 200. Moreover, when the worker attaches the light source unit 200 to the lighting fixture 100, the light source unit 200 can be easily attached to the lighting fixture 100 without a special jig that makes it easy to attach and detach the light source unit 200.

The spring 250 is formed so that, when the light source unit 200 is attached to the lighting equipment 100, the spring claw portion 252a does not protrude toward the bottom portion 111 from the spring bottom surface portion 252b inside the lighting equipment 100. Therefore, the lighting device 1 can suppress interference with other members inside the appliance main body 110 when the spring claw portion 252a is elastically deformed. Further, the lighting device 1 can prevent members disposed inside the appliance main body 110, such as electric wires, from interfering with the spring claw portion 252a and being damaged.

The spring 250 is formed in a V-shape such that the spring claw portion 252a is convex on one side of the spring bottom surface portion 252b. Therefore, the lighting device 1 can suppress interference with other members inside the appliance main body 110 when the spring claw portion 252a is elastically deformed. Further, the lighting device 1 can prevent members disposed inside the appliance main body 110, such as electric wires, from interfering with the spring claw portion 252a and being damaged.

A plurality of spring claws 252a of the spring 250 are formed in the longitudinal direction (X-axis direction) of the light source unit 200, and an opening is formed between adjacent spring claws 252a. The spring 250 can be easily elastically deformed by forming an opening between adjacent spring claw parts 252a. Further, the elasticity of the spring 250 can be adjusted by the size of the opening formed between the adjacent spring claw parts 252a, and the elastic strength of the spring formed of a plate material can be adjusted and the weight reduced. Can be done.

When the light source unit 200 is attached to the lighting fixture 100, the spring engaging part 252c comes into contact with the convex part 114 and slides, and the spring claw part 252a elastically moves in the lateral direction (Y-axis direction) of the lighting fixture 100. transform. Therefore, when the operator pushes the light source unit 200 into the lighting fixture 100 in the vertical direction (Z-axis direction) of the lighting device 1, the spring engaging part 252c engages with the convex part 114 of the lighting fixture 100, and the light source unit 200 can be easily fixed to the lighting fixture 100. Furthermore, when the worker inserts the light source unit 200 into the lighting fixture 100, the spring engaging portion 252c serves as a guide for the light source unit 200 with respect to the lighting fixture 100, making it easy for the worker to attach the light source unit 200. Therefore, since the spring engaging portion 252c serves as a guide for the light source unit 200 with respect to the lighting fixture 100, when the lighting device 1 is used as indirect lighting, etc., the light source unit 200 can be connected to the lighting fixture even if the installation space for the lighting device 1 is narrow. 100 can be easily attached.

When the spring 250 is attached to the frame 220, a gap is formed between the spring bottom portion 252b and the second plate portion 223. Therefore, the spring 250 can increase the distance between the end on the spring engaging part 252c side that contacts the convex part 114 and the end (fulcrum) on the V-shaped apex side of the spring claw part 252a, The spring 250 can be made elastically deformable easily.

In the light source unit 200, when the frame 220 is inserted into the lighting fixture 100 and the spring engaging portion 252c is disposed below the convex portion 114, the first plate portion 221 comes into contact with the convex portion 114. Therefore, when an operator inserts the light source unit 200 into the lighting fixture 100, the light source unit 200 is prevented from entering the interior of the fixture main body 110 beyond a predetermined distance, and the inside of the light source unit 200 and the lighting fixture 100 is Interference with parts can be prevented.

The spring hook part 251 of the spring 250 has two hook-shaped claw parts 251a1 facing each other at the tip. Therefore, the end of the spring 250 can be hooked onto the second plate portion 223 of the frame 220.

In addition, for lighting devices in which the light source unit is removably attached to the lighting fixture, it is considered that the lighting device has a spring that allows the light source unit to be attached to the inside of the lighting fixture body. It will be done. In the case of such a lighting device, the force of this spring is strong, and it is conceivable that a part of the light source unit will be drawn into the inside of the fixture body in the longitudinal direction (X-axis direction) of the lighting device. On the other hand, if the lighting device 1 is gripped in the lateral direction (Y-axis direction) by the convex portion 114 of the fixture body 110 and the spring engaging portion 252c, such a problem may occur. It can also be prevented.

[Function and effect of end cap 240]
The light source unit 200 includes a cover 230 that has an opening 230c formed at an end 230t in the longitudinal direction (X-axis direction) when attached to the frame 220, and an end cap 240 that is fixed to the frame 220 and closes the opening 230c. Equipped with. Since the end cap 240 of the light source unit 200 is fixed to the frame 220, even if the cover 230 contracts due to heat, the end cap 240 that is not fixed to the cover 230 is not affected. Therefore, even if the light source unit 200 is affected by heat, it is possible to suppress the load on each part of the light source unit 200.

The end cap 240 is fixed to the frame 220, and the length of the cover 230 in the longitudinal direction (X-axis direction) is shorter than the opposing length between the two cover cap parts 241 arranged at both ends of the frame 220. It is formed. Therefore, the lighting device 1 is not affected by the expansion and contraction of the cover 230 due to the influence of heat (ambient temperature), and can suppress expansion and contraction of the light source unit 200 in the longitudinal direction (X-axis direction). Further, the lighting device 1 can hold the cover 230 while suppressing the load on the cover 230 generated from the contact portion with the cover 230 based on the expansion and contraction of the cover 230 due to the influence of heat (ambient temperature).

When the end cap 240 closes the opening 230c, the inner side surface 230a of the cover 230 slidably contacts the first protrusion 242.

The light source unit 200 can draw out the light source side electric wire 213 to the outside of the frame 220 and the cover 230 using this opening. Therefore, in the lighting device 1, even if the cover 230 expands and contracts due to the influence of heat, the light source side electric wire 213 can be prevented from being pulled or pinched, and the load on the light source side electric wire 213 can be suppressed.

The substrate peeling prevention part 243a forms a gap between the second protrusion part 243a2 and the flat plate part 243e, and when the light emitting module 210 and the end cap 240 are combined, the end of the light emitting module 210 forms a gap. inserted into. Therefore, the light source unit 200 can prevent the substrate 212 constituting the light emitting module 210 from peeling off from the frame 220 and rising up.

In the light source unit 200, when the end cap 240 is fixed to the frame 220, the head of the screw fixture 260 protrudes from the end cap 240. Therefore, when attaching the light source unit 200 to the lighting fixture 100, the screw fixture 260 comes into contact with the end plate portion 150 of the lighting fixture 100 before the end cap 240 does. Therefore, in the lighting device 1, the end cap 240, which is a resin member, can avoid contact with the end plate portion 150, and the end cap 240, which is a resin member, can be prevented from being deformed or damaged.

As described above, the lighting device 1 can have the above-described effects of the light source unit 200 by having the light source unit 200 including the above-described end cap 240.

The engagement groove 3112 and the engagement wall 3113 suppress rotation of the hook 4100 and prevent the hook 4100 from protruding in the lateral direction (Y-axis direction) of the spring 3000. Therefore, when the light source unit 200 is attached to the fixture body 110, the engagement groove 3112 and the engagement wall 3113 cause the fall prevention part 4000 to protrude in the lateral direction and become caught between the light source unit 200 and the fixture body 110. This can be suppressed. As a result, the lighting device 1 can suppress attachment defects between the light source unit 200 and the fixture main body 110.

Further, in the lighting device 1, the engagement portion 3111, the engagement groove 3112, and the groove portion 3114 are the same in the longitudinal direction (X-axis direction) of the light source unit 200 when the spring 3000 is attached to the light source unit 200. placed in a straight line. As a result, when attaching the light source unit 200 to the instrument main body 110, the fall prevention section 4000 can be accommodated in the groove section 3114. Therefore, in the lighting device 1, by accommodating the fall prevention part 4000 in the groove part 3114, it is possible to suppress attachment failure between the light source unit 200 and the fixture main body 110 without sandwiching the fall prevention part 4000.

Further, the spring 3000 has spring arm portions 3210 that engage with the frame 220 at both ends of the spring bottom surface portion 3200. The spring arm portion 3210 holds the frame 220 in the transverse direction (Y-axis direction) like the engagement spring portions 1160a provided in pairs in the instrument-side spring 1160, and holds the frame 220 in the transverse direction (Y-axis direction) of the spring 3000. Unintentional movement in the axial direction) can be suppressed. Further, the spring arm portion 3210 can prevent the spring 3000 from being fixed to one side in the transverse direction (Y-axis direction). Therefore, since the spring 3000 has the spring arm portion 3210, when the light source unit 200 is attached to the instrument main body 110, the spring 3000 can be biased to either side in the short direction (Y-axis direction). Or, it is possible to suppress movement. Therefore, the spring 3000 has the spring arm portion 3210, which solves the problem that the spring engaging portion 252c becomes difficult to elastically deform or difficult to attach due to the uneven arrangement of the spring 3000. can. That is, in the lighting device 1, since the spring 3000 has the spring arm portion 3210, the light source unit 200 can be easily attached to the fixture main body 110.

Further, the spring arm portion 3210 includes a spring side wall portion 3210a rising from the spring bottom surface portion 3200, and a spring hook piece 3210b formed at the tip of the spring side wall portion 3210a and engaging with the second plate portion 223. Since the spring arm portion 3210 includes a spring side wall portion 3210a and a spring hooking piece 3210b, the spring arm portion 3210 can hold the frame 220, and can ensure engagement with the frame 220.
