Slide against. The engagement receiving portion 350 is fixed to the unit plate-shaped main body portion 311 by fixing the receiving portion-side mounting portion 352 to the main body side mounting portion 311a formed on the unit plate-shaped main body portion 311 with a screw.

(Attaching process of light source unit 300 to lighting apparatus 200)
Next, with reference to FIGS. 10-12, the process of attaching the light source unit 300 to the lighting fixture 200 is demonstrated.
(1) First, the operator inserts the engaging claw 312b of the hooking claw portion 312a of the light source unit 300 so as to hook the hooking hole 222a of the lighting fixture 200 from the outside. That is, the engaging claw 312b is passed through the hooking hole 222a in the direction of the arrow X in FIG.
(2) Thereafter, the operator lifts the light source unit 300 in the direction of the arrow as shown in FIG. 10, and moves the tip end portion 233 of the mounting spring 230 to the opening edge portion 351-1 of the engagement receiving portion 350 of the light source unit 300. Hang on. At this time, as shown in FIG. 12, the light source unit 300 can be in a temporarily fixed state in which it is hung on the lighting fixture 200.

  Therefore, in a state where the light source unit 300 is temporarily fixed, the operator can connect the electric wire connector 400M drawn from the power terminal block 240 arranged in the lighting fixture 200 and the electric wire drawn from the power source 330 of the light source unit 300. The connector 400L can be connected. Therefore, the connection between the lighting fixture 200 and the light source unit 300 can be easily performed.

  Next, when the light source unit 300 is pushed up from the temporarily fixed state of the light source unit 300, the light source unit 300 can be pulled up toward the lighting fixture 200 by the spring force (restoring force) of the mounting spring 230. The state where the unit 300 is pulled up can be maintained.

<*** Explanation of effects *****>
In this manner, the light source unit 300 is attached to the lighting fixture 200 by the set of the hook hole 222a and the engagement claw 312b, the mounting spring 230, and the engagement receiving portion 350. The hooking claw portion 312a, the attachment spring 230, and the engagement receiving portion 350 can be dispersed. For this reason, since the load concerning the attachment spring 230 can be reduced, it is possible to delay the progress of the aging deterioration (spring property deterioration or sag) of the attachment spring 230 due to the load of the light source unit 300 being applied.

  1, 2, 3, and 4, the lighting fixture 200 is provided with an inclined portion 221, and the plate of the rectangular plate-like appliance plate-like main body portion 210 rather than the rectangular plate-like unit main body 310. The area was reduced. Therefore, as shown in FIG. 13, when the lighting device 100 is attached to the ceiling, when a person looks up, the lighting fixture 200 is hidden by the light source unit 300, so that the design of the lighting device 100 can be improved.

  In the hook claw portion 312a, the engagement claw 312b protrudes inward as shown in FIG. 9, and is inserted into the hook hole 222a in the X direction (FIG. 2). On the other hand, as shown in FIG. 14, the engaging claw 312b protrudes outward, and the engaging claw 312b is inserted into the hooking hole 222a from the inner side (opposite to the X direction) of the hooking hole 222a and hooked. The light source unit 300 may be attached to the lighting fixture 200.

  The two engagement receiving portions 350 described in the first embodiment are the light source side engagement portions 600 that engage with the two attachment springs 230 that are counterpart components. There may be a plurality of light source side engaging portions 600, and although two cases are shown in this embodiment, they may be arranged in three, four, or the like.

  In the first embodiment described above, the plurality of engagement receiving portions 350 are arranged on one surface of the unit plate-shaped main body portion 311. However, the arrangement of the engagement receiving portion 350 and the mounting spring 230 is reversed, that is, the plurality of engagement receiving portions 350 are arranged in the instrument plate-like main body portion 210 and the attachment spring 230 is arranged in the unit plate-like main body portion 311. May be.

  Each of the plurality of attachment springs 230 corresponds to the engagement receiving portion 350, but the number of attachment springs 230 is the same as that of the engagement reception portion 350 and is the same as the number of attachment springs 230.

  As described above, the light source unit 300 is detachably attached to the lighting fixture 200. The LED that is the light source module is disposed on the other surface of the unit plate-shaped main body 311 along the other side facing the one side along the engagement receiving portion 350, and is an attachment that is a counterpart component of the light source side engaging portion 600 A hooking claw portion 312 a that is a hooking portion 500 that is hooked on a hooking fixture 250 of a mating part different from the spring 230 is provided.

  The hooking claw portion 312a that is the hooking portion 500 is disposed so as to protrude in an inner direction that is a direction from the other side toward the one side.

  The hooking portion 500 may have a shape that protrudes outward from the unit plate-shaped main body 311 that is a direction from the one side toward the other side.

The unit plate-shaped main body 311 has a side wall-shaped frame portion 312 rising from the other side.
The hook portion 500 may be formed integrally with the frame portion 312.

  In the lighting fixture 200, the mounting is a plurality of fixture-side engaging portions 700 that are arranged along one side of the fixture plate-like main body 210 and engage with an engagement receiving portion 350 that is a counterpart component arranged in the light source unit 300. A hook that is formed on the spring 230 and the other side opposite to the one side and is hooked with a hook part 222a that is two tool side hook parts 800 on which a mating part different from the phase part of the tool side engaging part 700 is hooked. An upright portion 222 which is an arrangement portion is provided.

  The plurality of instrument-side hooks 800 are opening hook holes 222a.

  As shown in FIGS. 1, 3, 4 (a), FIG. 11, and the like, in the lighting device 100 of the first embodiment, the light source unit 300 includes the unit plate-shaped main body 311 and the fixture plate of the lighting fixture 200. The lighting device 200 is attached to the lighting device 200 in an arrangement state so that the device plate-like main body portion 210 is on the upper side and the unit plate-like main body portion 311 is on the lower side. And the light source unit 300 is larger than the lighting fixture 200 in the horizontal direction which is a direction perpendicular to the vertical direction in the arrangement state.
