<P>PROBLEM TO BE SOLVED: To provide a lifting device for illumination which achieves downsizing of the lighting device body, houses a cord reel efficiently in the luminaire to improve handling of an electric wire, and in which winding up and feeding operation of the electric wire can be made further smoothly with stable lifting operation, and an unstable factor such as inclination of the luminaire during lifting operation can be eliminated. <P>SOLUTION: An electric wire 3 which supplies power supply from a lifting device body 1 to the luminaire 8 is suspended, and a cord reel 11 for winding up or feeding the electric wire 3 according to lifting operation of the luminaire 8 is housed in the central space 9 surrounded by an annular lamp 3 in the luminaire 8. The cord reel 11 is arranged so that the winding up center axis M of the electric wire 3 may be horizontal in a state that an electric wire leading out entrance 11a in which the electric wire 3 comes in and out faces toward the ceiling 4 side. <P>COPYRIGHT: (C)2008,JPO&INPIT |
