[Action and effect of frame 220]
The following describes the thinning of the lighting device 1 by the frame 220, which is an effect of the lighting device 1 according to the embodiment. 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. Therefore, the light source unit 200 can be made thinner without increasing in the vertical direction (Z-axis direction). As a result, the lighting device 1 having the light source unit 200 can be thinned in the vertical direction (Z-axis direction).

Further, the lighting device 1 can effectively utilize the internal space of the fixture main body 110 by reducing the thickness of the light source unit 200. 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 making the light source unit 200 thinner. The fixture body 110 can be divided 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 in the vertical direction (Z-axis direction) by reducing the thickness of the light source unit 200. can. The lighting device 1 can move the power supply device 120 to one side in the lateral direction (Y-axis direction) by dividing the inside of the fixture main body 110 into upper and lower parts. Therefore, the lighting device 1 can be provided with a storage portion for the electric wire in the fixture in the lateral direction (Y-axis direction) of the fixture main body 110, and can suppress the increase in size of the lighting device 1. Further, the lighting device 1 can prevent the electric wire from being sandwiched between the light source unit 200 and the power supply device 120 by accommodating the electric wire in the instrument in the lateral direction (Y-axis direction) of the instrument main body 110. can. With these configurations, the lighting device 1 can be miniaturized.

[Action and effect of spring 250]
In the lighting device 1, the spring 250 fixed to the light source unit 200 is formed at both ends of the spring bottom surface portion 252b formed in a flat plate shape and the spring bottom surface portion 252b, and the light source unit 200 is formed in the lateral direction (Y-axis direction). It has a spring claw portion 252a that elastically deforms. Further, the spring 250 has a spring engaging portion 252c formed at the tip end portion of the spring claw portion 252a. The distance L1 of the closest portion of the corresponding two convex portions 114 is smaller than the distance of the farthest portion 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, so that the light source unit 200 can be engaged with the convex portion 114 of the fixture main body 110 via the spring 250. can. Further, the operator can remove the light source unit 200 from the luminaire 100 by pulling out the light source unit 200 from the luminaire 100 and utilizing the elastic deformation of the spring 250. As a result, the lighting device 1 can easily attach / detach the light source unit 200 to / from the lighting fixture 100.

In the spring 250, when the light source unit 200 is attached to the luminaire 100, the spring engaging portion 252c engages with the convex portion 114. Therefore, the lighting device 1 does not need to provide a separate member for engaging with the spring 250 in the fixture main body 110 of the lighting fixture 100, and the number of member points 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.

When the light source unit 200 is attached to the luminaire 100, the spring engaging portion 252c of the spring 250 is formed in an arc shape at a portion facing the side surface portion 112. Therefore, when the operator removes the light source unit 200 from the luminaire 100, the light source unit 200 can be easily removed from the luminaire 100 without a special jig that makes it easy to attach and detach the light source unit 200. 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 makes it easy to attach and detach the light source unit 200.

The spring 250 is formed so that the spring claw portion 252a does not protrude toward the bottom portion 111 from the spring bottom surface portion 252b inside the lighting fixture 100 when the light source unit 200 is attached to the lighting fixture 100. Therefore, the lighting device 1 can prevent the spring claw portion 252a from interfering with other members inside the instrument main body 110 when it is elastically deformed. Further, in the lighting device 1, for example, a member arranged inside the instrument main body 110 such as an electric wire can be prevented 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 is convex on one surface side of the spring bottom surface portion 252b. Therefore, the lighting device 1 can prevent the spring claw portion 252a from interfering with other members inside the instrument main body 110 when it is elastically deformed. Further, in the lighting device 1, for example, a member arranged inside the instrument main body 110 such as an electric wire can be prevented 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 an opening is formed between the adjacent spring claw portions 252a. The spring 250 can be easily elastically deformed by forming an opening between the adjacent spring claw portions 252a. Further, the spring 250 can adjust the elasticity of the spring 250 by the size of the opening formed between the adjacent spring claw portions 252a, and the elastic strength of the spring formed of the plate material can be adjusted and the weight can be reduced. Can be done.

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

When attached to the frame 220, the spring 250 forms a gap between the spring bottom surface portion 252b and the second plate portion 223.
