PURPOSE:To horizontally hold a reflector, closely adhere it to a dressed ceiling surface, and receive it in an embedded frame when the relative positions of a lifting device and the embedded frame fitted to the opening part of the dressed ceiling surface are not coincident to each other. CONSTITUTION:An embedded frame 2 to be fitted to the opening part 6 of a dressed ceiling surface 3 is fixed to a body frame 1 fixed in the inner part of a ceiling, a lifting device 7 for raising and lowering a lifting part 8 is provided on the upper part of the body frame 1, and a reflector 16 opposite to a lamp 17 and a socket base 13 for holding a lamp socket 14 are provided. A plurality of guide pins 23 the upper ends of which are held by a part of the lifting part 8 in such a manner as to be capable of oscillating are inserted to the socket base 13, and the rising force of the lifting part 8 is transmitted to the socket base 13 by springs 26 the lower ends of which are held by the lower ends of the guide pins 3. The central lien of the reflector 16 is situated on the central vertical line of the embedded frame 2 while the center of the lifting part 8 is situated in the center of the lifting device 7 by the oscillating motion of the guide pins 23, the reflector 16 is kept in the state parallel to a dressed ceiling surface 3, and the whole outer circumference is received in the embedded frame 2. |
