<P>PROBLEM TO BE SOLVED: To reduce cost by sharing a lifting device for luminaires of different sizes and to achieve a stable lifting operation without rotation of a luminaire in a lifting-type luminaire including the lifting device for lifting the luminaire. <P>SOLUTION: The lifting-type luminaire includes: a lifting device 1; a luminaire body 21 suspended by a lifting wire 11 lifted by a lifting reel 12 of the lifting device 1; a rotation preventing wire 31 preventing the luminaire body 21 from rotation; and a rotation preventing reeler 32 arranged away from the lifting reel 12 and winding/unwinding the rotation preventing wire 31. The lifting wire 11 is fixed at the center section of the luminaire body 21, and the rotation preventing wire 31 is fixed in a periphery away from the center section. Therefore, the luminaire body 21 can be hardly rotated horizontally even when the lifting wire 11 is fixed at the center section by the rotation preventing wire 31, so that cost is reduced by sharing the lifting device irrespective of a size of a luminaire 2 and a stable lifting operation without rotation of the luminaire is achieved. <P>COPYRIGHT: (C)2010,JPO&INPIT |
