DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, embodiments of the present invention will be described. However, these are merely exemplary embodiments adopted based on the present invention, and the present invention is limited to matters unique to only the embodiments. The technical scope of the present invention must be determined based on the matters stated in the claims or matters that are substantially equivalent thereto.

In the illustrated embodiment, a support 2 having a substantially U-shaped cross section is mounted on the lower surface of the main body 1, and a human body sensor 3 and a cover mounting 4 provided around the human body sensor 3 are provided on the lower surface of the support 2. The cover 5 is provided with a mounting member 7 having a hole 6 facing the human body sensor 3 and locked by a rotation operation with respect to the cover mounting member 4.
Is a lighting fixture rotatably attached to the cover 5. More specifically, the human body sensor 3 is a pyroelectric infrared sensor, and includes the cover mounting member 4 and the mounted member 7.
Is formed of a substantially cylindrical synthetic resin. In the illustrated example, the outer periphery of the cover attachment 4 and the inner periphery of the attachment 7 are locked, but the upper part of the attachment 7 fits between the human body sensor 3 and the cover attachment 4 and the attachment A structure in which the outer periphery of the fixture 7 and the inner periphery of the cover attachment 4 are locked may be employed.

More specifically, the cover fixture 4
A plurality of projections 8 are formed on the outer periphery of the mounting member 7, and a plurality of recesses 9 having an opening on one side to be engaged with the projections 8 are formed on the inner circumference of the mounted member 7. A plurality of pins 11 urged by a spring 10 protrude from the outer periphery of the cover mounting member 4, and a locked portion comprising a plurality of concave portions 12 on the inner circumference of the mounted member 7 for locking the pins 11. Is provided. A plurality of guides (ribs) 13 are provided between the human body sensor 3 and the cover mounting member 4 so as to rise obliquely from the human body sensor 3 toward the lower end of the cover mounting member 4 and also serve to reinforce the cover mounting member 4. During the process of attaching the cover 7 to the cover fixture 4, the guide 13
Is guided by the lower end of the outer periphery of the cover attachment 4. In a state where the cover 5 is attached by the attachment of the attachment 7 and the cover attachment 4, the lower surface of the support 2 and the upper end of the attachment 7 are almost in contact with each other. The attachment 7 comprises a cylindrical portion 14 and a decorative ring 15 which gently sandwich the edge of a hole formed in the center of the cover 5, and these are fixed to each other by screws or other appropriate means. It is mounted rotatably.

[0008] More specifically, the main body 1 is supported by a locked member 19 which is locked by a hook plug 18 connected to a hooking rosette 17 fixed to the ceiling 16 with screws. On the upper surface of the main body 1, there is a base plate 21 supporting the lighting circuit board 20 on the lower surface. The base plate 21 is fixed to the main body 1 and the spacers 22 at an interval. A lamp 24 is provided on the lower surface of the main body 1 through a socket 23.
Is installed.

In order to attach the cover 5 to the cover attachment 4, the cover 5 is lifted by holding the decorative ring 15 so that the human body sensor 3 faces the hole 6 of the attachment 7 to be attached. Even if the hole 6 and the human body sensor 3 are slightly displaced from each other, the upper end of the mounted member 7 is guided by the guide 13 by pushing up the cover 5, and the upper portion of the mounted member 7 is guided by the outer periphery of the cover mounting member 4. You. When the decorative ring 15 is rotated clockwise as viewed from below, the pin 11 rides over the convex wall 12 a immediately before the concave portion 12. After that, the projection 8 is easily fitted into the recess 9, and the projection 8 is easily fitted into the recess 9. At this time, when the pin 11 returns in the protruding direction by the urging force of the spring 10 and the wide portion 11a at the base of the pin 11 hits the inner surface of the cover fixture 4, a sound is generated, and the user can securely attach the cover 5. You can sense that. That is, the projection 8 is not fitted into the recess 9 unless the pin 11 climbs over the projection wall 12a to generate a sound, so that incomplete locking engagement can be prevented. To remove the cover 5, the reverse process may be performed. When the cover 5 is attached, the lower convex wall forming the concave portion 12 is locked by the convex portion 8, and the tip of the pin 11 is located in the concave portion 12. Even if the projection 8 is damaged, the cover 5 is prevented from dropping by the locking action of the recess 12 and the pin 11.

According to the present embodiment, there is a cover attachment 4 provided around the human body sensor 3 on the lower surface of the support 2, and a cover 7 having a hole 6 is provided in the cover 5, The cover 5 is rotatably attached to the cover 5, so that the cover 5 can be easily attached to the cover attachment 4 only by pushing up the cover 5 and then rotating the small attachment 7. Mounting and centering of the human body sensor 3 with respect to the cover 5 can be facilitated. Further, since the cover 5 can be rotated after the attachment, the direction of the pattern can be harmonized with the room when the cover 5 has a pattern or the like, which is convenient.
