Hereinafter, embodiments of the present invention will be described in detail. However, it should be noted that the drawings are schematic and dimensional ratios and the like are different from actual ones. Therefore, specific dimensional ratios and the like should be determined in consideration of the following description. Moreover, it is a matter of course that portions having different dimensional relationships and ratios are included between the drawings.
The following embodiments are exemplifications for embodying the technical idea of the present invention, and the embodiments of the present invention are described below in terms of the material, shape, structure, arrangement, etc. of the components. It is not something specific. The embodiments of the present invention can be implemented with various modifications without departing from the scope of the invention.

1 and 2 are perspective views of a lighting apparatus according to the present invention. The luminaire according to the present invention is formed in a long shape and is mainly installed on a ceiling surface. Reference numeral 1 denotes an instrument body. Reference numeral 2 denotes a light source unit, which is attached to the recess 10 of the instrument body 1 by an attachment spring 6. FIG. 1 shows a state where the light source unit 2 is attached to the instrument body 1, and FIG. 2 shows a state where the light source unit 2 is removed from the instrument body 1.

FIG. 3 is a cross-sectional view of a lighting fixture according to the present invention. The instrument body 1 is formed in a long shape, and a rectangular recess 10 for accommodating the light source unit 2 extends in the longitudinal direction of the instrument body 1 on the side opposite to the ceiling surface (lower side in the figure). Is formed. The width direction (left-right direction in the figure) of the instrument body 1 is an inverted Fuji type that is inclined toward the ceiling as it goes outward.

The recess 10 has a pair of side wall portions 11 and a bottom surface portion 12 that extend in the longitudinal direction of the instrument body and face each other. An opening of the recess 10 is formed by the opening end 9 that is the end of the side wall 11 opposite to the bottom surface 12. A convex portion 8 is formed in the concave portion 10 on the side wall portion 11 on the side of the bottom surface portion 12 slightly from the opening end 9 toward the inside of the concave portion 10 from the side wall portion 11 substantially perpendicularly (that is, toward the side wall portions 11 facing each other). It is formed along the longitudinal direction. An attachment spring 6 for attaching the light source unit 2 is disposed in the recess 10.

The light source unit 2 includes a substrate 4 on which the light emitting element 5 is mounted, an attachment member 7 that holds the substrate 4, and a cover 3 that is attached to the attachment member 7 so as to cover the light emitting element 5. The attachment member 7 includes a base portion 7a for holding the substrate 4, a pair of connection portions 7b extending from the base portion 7a toward the housing portion of the instrument body 1, and a width of the attachment member 7 from each connection portion 7b. It has the extending | stretching part 7c extended | stretched toward the outer side of a direction (left-right direction in a figure).

FIG. 4 is a cross-sectional view of the lighting fixture according to the present invention, in which the light source unit 2 is attached to the fixture body 1. The light source unit 2 is attached to the instrument body 1 by fitting the connection portion 7b of the attachment member 7 and the attachment spring 6 attached in the recess 10 of the instrument body 1.

At this time, the extending portion 7 c of the attachment member 7 is in a state of overlapping and contacting the convex portion 8 provided on the side wall portion 11 of the concave portion 10 so as to cover from the opening end 9 side. In this way, by configuring the extending portion 7c and the convex portion 8 so as to be in contact with each other, heat generated from the substrate 4 on which the light emitting element 5 is mounted is transferred from the base portion 7a to the extending portion 7c, and further, By being transmitted to the part 8 and the fixture body 1, it becomes possible to efficiently dissipate heat in the entire lighting fixture.

Further, the convex portion 8 is continuously formed along the longitudinal direction in the concave portion 10, and the extending portion 7 c of the attachment member 7 is also continuously formed along the longitudinal direction of the attachment member 7. By attaching the light source unit 2 to the instrument main body 1 so that the extending portion 7c covers the convex portion 8 from the opening side, there is no gap between the light source unit 2 and the concave portion 10. Therefore, the appearance in the state where the light source unit 2 is turned on is improved. Further, the convex portion 8 also serves as a stopper so that the light source unit 2 does not enter the concave portion 10 too much. Since the extending portion 7 c contacts the convex portion 8, the light source unit 2 is prevented from entering the concave portion 10 more than necessary.

Since the convex portion 8 is formed on the side wall portion 11 on the side of the bottom surface portion 12 slightly from the opening end 9, a certain distance L is provided between the opening end 9 and the convex portion 8 in the side wall portion 11. This distance L prevents the attachment member 7 from being exposed to the outside in a state where the light source unit 2 is attached to the instrument body 1. In other words, the attachment member 7 is surrounded by the side wall portion 11 by providing a certain distance L between the opening end 9 and the convex portion 8 in the side wall portion 11. When the mounting member 7 is disposed at a position where it can be seen by human eyes, the appearance of the appearance is deteriorated. By surrounding the attachment member 7 with the side wall portion 11, the attachment member 7 can be prevented from being exposed to the outside, and the appearance of the lighting fixture can be improved. For this reason, the distance L only needs to be long enough to prevent the attachment member 7 from being exposed to the outside, and may be formed to surround a portion of the cover 3.
