<P>PROBLEM TO BE SOLVED: To ensure a wide oscillating range of a lamp body in an embedded luminaire when the lamp body is provided to freely oscillate with a reduced space from a wall surface of an embedding hole. <P>SOLUTION: The embedded luminaire comprises the lamp body 5, a cylindrical support frame 3 supporting the lamp body 5, and a spiral coil spring 2 having an inside diameter substantially equal to the outside diameter of the support frame 3 and an outside diameter larger than the opening diameter of the embedding hole C2. The support frame 3 is fitted in the embedding hole C2. A radially inside end part 2a of the coil spring 2 fastens and holds the outer circumferential surface of the support frame 3, and a radially outside end part 2b of the coil spring 2 is disposed around the embedding hole C2 in a back surface C3 of a luminaire mounting surface C1. Therefore, even if the lamp body 5 is inclined by oscillation, contact of the lamp body 5 with the coil spring 2 can be avoided, and the oscillating range of the lamp body 5 can be extended. Further, since it is the coil spring 2 that fixes the support frame 3, an extended clearance between the wall surface of the embedding hole C2 and the support frame 3 for using the elastic force of the spring is not needed, and this clearance can be minimized. <P>COPYRIGHT: (C)2008,JPO&INPIT |
