The second fixing member 5 is attached by hooking the two hook portions 52 onto the outer peripheral wall 16c of the radiator plate 16a. As shown in FIG. 9, the operation of hooking the hook portion 52 to the outer peripheral wall 16c of the heat sink 16a involves inserting the hook portion 52 into the inside of the heat sink 16a while tilting the second fixing member 5, and then tilting it. This is done by returning the second fixing member 5 in the folded state to the original state shown in FIG.

Next, as shown in FIG. 10, the contact surface portion 30a of the case member 3 is brought into contact with the intermediate strut member 13b, and the engaging portion 40 of the first fixing member 4 is inserted into the concave portion 14b of the support mechanism 14, whereby the first fixing is performed. The member 4 is slid downward to combine the engaging portion 40 with the convex portion 14a. The first fixing member 4 is slid downward until the bottom surface of the case member 3 hits the holding portion 53 of the second fixing member 5 .

Then, as shown in FIG. 11, the fastening member 6 is commonly inserted into the through hole 52a of the hook portion 52 and the through hole 41a of the joint portion 41 of the first fixing member 4 and fastened. The fastening member 6 may have a structure in which screw members are screwed into the through holes 41a and 52a, or may be fastened with bolts and nuts. As described above, the functional component 2 is attached to the lighting fixture 1 to complete the lighting device 100 .

As shown in FIG. 2, the functional component 2 is attached to the lighting device 1 so that the light receiving section 35 exposed from the case bottom portion 31 is above the bottom surface of the cover member 18. As shown in FIG. This is to prevent the light receiving section 35 from contacting the temporarily placed place and being damaged when the lighting device 100 is temporarily placed.

Because of the structure, the lighting fixture 1 can be attached without forming an insertion hole for inserting the fastening member, and the strength of the strut framework 13 can be maintained.

The second fixing member 5 also has a holding portion 53 that contacts the bottom surface of the case member 3 on which the first fixing member 4 is slid to hold the case member 3 at a target position. Therefore, the functional component 2 can stably hold the case member 3 when attached to the lighting device 1 . In addition, the functional component 2 prevents the case member 3 from falling because the holding portion 53 abuts on the bottom surface of the case bottom portion 31 . can be held and prevented from falling.

Further, the sensor member 33 and the connector 36 are mounted on the sensor substrate 32 so as to be positioned on the bottom surface of the case member 3 held by the holding portion 53 . The sensor member 33 is provided so that a part (light receiving portion 35 ) is exposed from the bottom surface of the case member 3 . The holding portion 53 is provided to face the connector 36 while avoiding the exposed sensor member 33 . Therefore, since the functional component 2 has a configuration in which the connector 36 is arranged in the space created by avoiding the sensor member 33 with the holding portion 53 exposed, the space can be effectively utilized, and the case member 3 can be made smaller and lighter. can be
