As shown in FIG. 7, the light source unit 100 is attached to the concave portion 211 with the device attachment surface portion 111 d that is the back surface of the substrate attachment surface portion 111 a facing the bottom surface portion 211 a of the concave portion 211. The light source unit 100 is attached to the recess 211 with the cover side 131 facing the opening edge 211ba.
At this time, the cover side portion 131 and the opening edge portion 211ba are arranged with a predetermined distance therebetween. That is, the gap 190 is formed between the cover side 131 and the opening edge 211ba.
As shown in FIG. 8, the gap 190 is formed at the boundary in the longitudinal direction between the lighting device 200 and the cover 130.

As shown in FIG. 7, the cover 130 includes a cover front surface portion 132 that faces the light emitting element 120a. The cover front surface portion 132 is formed continuously from the lower ends of the cover side portions 131 on both sides in the short direction.
The cover side portion 131 includes a cover engaging portion 1311 and a cover side surface portion 1313. Further, the cover side surface portion 1313 includes a cover protruding portion 1312.
The cover engaging portion 1311 covers the upright portion 112 and engages with the upright portion 112. The cover side surface portion 1313 is formed continuously from the end portion in the short direction of the cover front surface portion 132 toward the substrate mounting surface portion 111a. The cover protruding portion 1312 is formed between the cover engaging portion 1311 and the cover side surface portion 1313 and protrudes away from the central portion of the recess 211.
The gap 190 is formed between the cover protrusion 1312 and the opening edge 211ba.

The cover engaging portion 1311 is formed along the upright portion 112 inside the upper portion of the cover side surface portion 1313.

The cover protruding portion 1312 protrudes from the portion where the cover side surface portion 1313 is joined to the outer portion of the cover engaging portion 1311 toward the opening edge 211ba in a state where the light source unit 100 is attached to the lighting fixture 200.

  The distance separating the cover side portion 131 and the opening edge portion 211ba, that is, the gap portion 190 is a dimension through which a gas such as air can pass without impairing the design, and is preferably about several millimeters, and preferably about 1 mm to 5 mm. 2 mm to 4 mm is particularly preferable. The gap 190 may be other than the above numerical values.

As shown in FIG. 8, a through hole 2501 that penetrates the bottom surface portion 211 a such as a power supply wire insertion hole 250 and a bolt insertion hole 251 is formed in the bottom surface portion 211 a of the recess 211. These through holes 2501 have dimensions that allow gas such as air to pass through.
The air that has passed through the gap 190 and has flowed into the recess 211 passes through the through-hole 2501 formed in the bottom 211a and flows out of the recess 211. That is, as shown by the arrow in FIG. 7, an air flow path is formed inside the recess 211.
When the light source unit 100 operates, the lighting device 10 generates operating heat from the light emitting element 120a that emits light (lights up) and the power supply device 140 that generates lighting power, and the temperature of the air inside the recess 211 increases. The air whose temperature has risen moves upward, passes through the through hole 2501 formed in the bottom surface portion 211a, and flows out of the recess. Then, air having a low temperature passes through the gap 190 and flows into the recess 211. In this way, the heat generated from the light source unit 100 is discharged outside the lighting device.
A through hole 2501 such as a power supply line insertion hole 250 and a bolt insertion hole 251 is formed in the bottom surface portion 211a of the recess 211. However, in addition to the power supply line insertion hole 250 and the bolt insertion hole 251, the air flow A through hole may be formed for the purpose of forming a path.

As shown in FIG. 7, the opening edge 211ba has a curved portion 211bb that is smoothly curved in a direction away from the central portion of the recess 211. The curved portion 211bb is formed by bending the side surface portion 211b of the recess 211 outward.
Moreover, the cover protrusion part 1312 forms the curved surface which protrudes toward the curved part 211bb.
As described above, the gap 190 has a shape in which air easily passes because both sides in the short direction are formed by curved surfaces.

As shown in FIGS. 1 and 2, the unit end 260 that is the end in the longitudinal direction of the light source unit 100 abuts on the recess end 2111 that is the end in the longitudinal direction of the recess 211. As shown in FIGS. 1 and 8, in the lighting device 10, a portion where the unit end portion 260 and the recessed portion end 2111 are in contact with each other is referred to as a contact portion 191.
In the contact portion 191, the unit end portion 260 and the recess end portion 2111 are in contact with each other. Moreover, in the clearance part 190, the elongate side part of the light source unit 100 and the opening edge part 211ba of the lighting fixture 200 have a clearance gap, without contacting. That is, the gap portion 190 exists in a slit shape on the long side portions on both sides of the light source unit 100.
