In addition, the housing portion 1110 has an opening 1113 into which the light source unit 200 is inserted at a position facing the bottom portion 1111.

  As shown in FIGS. 16 and 17, the flange portions 1112 are formed in pairs so as to be separated from the long side sides on the opening 1113 side of the pair of side portions 1112, and both sides in the short direction Y of the opening 1113. It is attached to. It should be noted that the collar portion 1112 is on the Y side in the short direction of the edge portion 1001 provided on the periphery of the opening 11113.

  The collar portion 1120 is provided with a recess 1121. The recessed portion 1121 has a shape recessed from the flange portion 1110 toward the bottom portion 1111, and is formed at a location adjacent to the spring 140 in the lateral direction Y.

  In a state where the light source unit 200 is attached to the lighting fixture 1000, the flange portion 1120 contacts the cover portion bottom portion 232 of the light source unit 200, and the recess portion 1121 forms a gap between the cover portion bottom portion 232. Due to the gap formed by the recess 1121, the operator can hold the light source unit 200 when attaching and detaching the light source unit 200 to and from the lighting fixture 1000, and the attachment / detachment work can be facilitated.

Further, the recess 112 is provided so as to be adjacent to the spring 140 in the short direction Y. Thereby, when removing the light source unit 200 from the lighting fixture 1000, the load on the light source unit 200 can be suppressed.
This is because when the end of the light source unit 200 in the longitudinal direction X is held and pulled, the light source unit 200 applies a pulling force to the distance between the end of the light source unit 200 in the longitudinal direction X and the spring 14 with the spring 140 as a fulcrum. Combined stress is applied.
With respect to this stress load, the recess 112 is provided so as to be adjacent to the spring 140 in the short direction Y, and the distance between the spring 140 and the portion holding the light source unit 200 can be reduced. Therefore, the stress load can be suppressed and the load on the light source unit 200 can be reduced.

  In the present embodiment, the lighting fixture 1000 is provided with a recess 1111 in the collar portion 1110 so as to be adjacent to the spring 140 in the short direction Y, and suppresses the load on the light source unit 200 from the lighting fixture 1000. Can be removed.

Next, a modified example of the recess 1121 will be described with reference to FIGS. 18 and 19.
18 is a detailed perspective view of the luminaire 1000A in which the recess 1121A is formed, and FIG. 19 is a cross-sectional view taken along the line II ′ shown in FIG. The light source unit 200 is shown as a reference in the HH ′ cross-sectional view of FIG. As a modification of the present embodiment, a lighting fixture 1000A provided with a recess 1121A as shown in FIG. 18 may be used.

  The hollow portion 1111A is formed in a concave shape so as to be inclined toward the inclined portion 113 side. The lighting fixture 1000A is formed in a concave shape such that the recess 1121A is inclined toward the inclined portion 113, so that when the light source unit 200 is attached to the lighting fixture 1000B, an operator's finger or jig, etc. The opening into which is inserted is large, and can be more easily gripped.

  In the present embodiment, the hollow portion 123 is illustrated and described as a substantially rectangular recess, but the grip portion 1000 may have an arc shape or a shape having a plurality of irregularities.

  In Embodiments 1 and 2, the lighting apparatus 100 and the lighting apparatus 1000 have been described with respect to the inverted Fuji type shape, but the lighting apparatus according to the present invention is not limited to the inverted Fuji type shape but has an embedded type shape. A lighting fixture or a trough-shaped lighting fixture may be used.

  As mentioned above, although embodiment of this invention was described, you may implement combining these embodiment. Alternatively, these embodiments may be partially implemented. Or you may implement combining these embodiment partially. In addition, this invention is not limited to these embodiment, A various change is possible as needed.
