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

In addition, since the light source unit 200 is thinned, the lighting device 1 can effectively utilize the internal space of the fixture body 110 . Specifically, the light source unit 200 can be attached to the lighting fixture 100 so as not to interfere with the parts housed in the fixture main body 110 such as the power supply device 120 by thinning the light source unit 200 . Since the light source unit 200 is thinned, the fixture main body 110 can be divided vertically (in the Z-axis direction) into a region in which the light source unit 200 is housed and a region in which the power supply device 120 and the like are housed. can. By dividing the interior of the fixture body 110 into upper and lower parts, the lighting device 1 can move the power supply device 120 to one side in the short direction (Y-axis direction). Therefore, in the lighting device 1 , it is possible to provide a housing portion for the wires in the fixture in the lateral direction (Y-axis direction) of the fixture main body 110 , thereby suppressing an increase in the size of the lighting device 1 . In addition, since the lighting device 1 accommodates the wires in the fixture in the lateral direction (Y-axis direction) of the fixture body 110, it is possible to prevent the wires from being caught between the light source unit 200 and the power supply device 120 or the like. can. With these configurations, the illumination device 1 can be miniaturized.

[Action and effect of spring 250]
In the illumination device 1, the springs 250 fixed to the light source unit 200 are formed in a flat plate-shaped spring bottom portion 252b, and are formed at both ends of the spring bottom portion 252b in the lateral direction (Y-axis direction) of the light source unit 200. 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 corresponding two 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 portion 252a. Therefore, the operator can use the elastic deformation of the spring 250 to push the light source unit 200 into the lighting fixture 100 , thereby engaging the light source unit 200 with the protrusion 114 of the fixture body 110 via the spring 250 . can. In addition, the operator can remove the light source unit 200 from the lighting fixture 100 by pulling out the light source unit 200 from the lighting fixture 100 using the elastic deformation of the spring 250 . As a result, the lighting device 1 can easily attach and detach the light source unit 200 to and from the lighting fixture 100 .

The spring engaging portion 252c of the spring 250 is engaged with the convex portion 114 when the light source unit 200 is attached to the lighting fixture 100 . Therefore, the luminaire 1 does not need to provide a separate member for engaging with the spring 250 in the luminaire body 110 of the luminaire 100, and the number of members can be reduced. Therefore, the lighting device 1 can reduce the number of parts accommodated 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 portion 112 when the light source unit 200 is attached to the lighting fixture 100 . Therefore, when a worker 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 for facilitating attachment and detachment of the light source unit 200. - 特許庁Further, 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 facilitates attachment and detachment of the light source unit 200.例文帳に追加

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

The spring 250 is formed in a V shape so that the spring claw portion 252a protrudes toward one side of the spring bottom surface portion 252b. Therefore, the illumination device 1 can suppress interference with other members inside the fixture body 110 when the spring claw portion 252a is elastically deformed. In addition, the lighting device 1 can prevent a member, such as an electric wire, disposed inside the fixture body 110 from interfering with the spring claw portion 252a and being damaged.

A plurality of spring claw portions 252a of the spring 250 are formed in the longitudinal direction (X-axis direction) of the light source unit 200, and openings are formed between adjacent spring claw portions 252a. The spring 250 can be easily elastically deformed by forming openings between adjacent spring claw portions 252a. In addition, the spring 250 can adjust the elasticity of the spring 250 according to the size of the opening formed between the adjacent spring claws 252a. can be done.

When the light source unit 200 is attached to the lighting device 100, the spring engaging portion 252c slides in contact with the convex portion 114, and the spring claw portion 252a is elastic in the lateral direction (Y-axis direction) of the lighting device 100. transform. Therefore, when the operator pushes the light source unit 200 into the lighting device 100 in the vertical direction (Z-axis direction) of the lighting device 1, the spring engaging portion 252c engages with the convex portion 114 of the lighting device 100, and the light source unit 200 can be easily fixed to the luminaire 100 . Moreover, when an operator inserts the light source unit 200 into the lighting fixture 100 , the spring engaging portion 252 c serves as a guide for the light source unit 200 with respect to the lighting fixture 100 , so that the worker can easily attach the light source unit 200 . Therefore, the spring engaging portion 252c serves as a guide for the light source unit 200 with respect to the lighting device 100, so that when the lighting device 1 is used as indirect lighting or the like, the light source unit 200 can be used as a lighting device even in a space where the lighting device 1 is installed in a narrow space. 100 can be easily attached.

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

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

The spring hooking portion 251 of the spring 250 has two claw portions 251a1 formed in the shape of hooks facing each other at the tip. Therefore, the spring 250 can be hooked on the second plate portion 223 of the frame 220 at its end.

In addition, in a lighting device in which a light source unit is detachably attached to a lighting fixture, it is conceivable that the lighting device has a spring that pulls the light source unit inside the main body of the lighting fixture. be done. In the case of such a lighting device, the force of the spring is so strong that part of the light source unit may be pulled inside the fixture body in the longitudinal direction (X-axis direction) of the lighting device. On the other hand, as in the lighting device 1, if the lighting device 1 is gripped in the lateral direction (Y-axis direction) by the convex portion 114 and the spring engaging portion 252c of the fixture body 110, such a problem can be solved. can also be prevented.

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

The end cap 240 is fixed to the frame 220, and the length in the longitudinal direction (X-axis direction) of the cover 230 is shorter than the facing length between the two cover cap portions 241 arranged at both ends of the frame 220. formed. Therefore, the illumination device 1 is not affected by expansion and contraction of the cover 230 due to heat (surrounding temperature), and can suppress expansion and contraction of the light source unit 200 in the longitudinal direction (X-axis direction). Moreover, the lighting device 1 can hold the cover 230 by 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 (surrounding temperature).

When the end cap 240 closes the opening 230c, the inner side surface 230a of the cover 230 slidably contacts the first projecting portion 242. As shown in FIG. Therefore, in the light source unit 200, the end cap 240 has the first projecting portion 242 and the cap-side cover holding portion 243c, so that the cover 230 is held so as to be movable in the longitudinal direction (X-axis direction). Therefore, the illumination device 1 can hold the cover 230 while suppressing the influence of thermal expansion and contraction of the cover 230 .

The end cap 240 is formed such that the first projecting portion 242 has higher permeability than the cover cap portion 241 . Therefore, the illumination device 1 can prevent the overlapped portion of the cover 230 and the first projecting portion 242 of the end cap 240 from becoming dark. For example, the internal space of the light source unit 200 can be seen from the longitudinal direction (X-axis direction) of the light source unit 200 by not increasing the transmittance of the cover cap portion 241 by two-color molding, or by suppressing the transmittance. can be suppressed.

The first protruding portion 242 of the end cap 240 is formed such that, in the protruding direction, the transparency is different between the tip portion side (region A) and the base portion side (region B). For example, since the light transmission distance is longer on the tip side (area A) that contacts the cover 230, the light source unit 200 as a whole can reduce light unevenness by increasing the transmittance of the tip side (area A). can be suppressed.

The first protruding portion 242 of the end cap 240 has an R-shaped end on the protruding side.
