  • Publication number: 20120275158
    Abstract: A drape with movable light sources mainly includes a light system and a partition disposed within a bracket. The light system has a light source respectively disposed in each first moving member of the drape. A first connecting unit disposed on each first moving member is pervious to light of the light source. Dragging the first moving member brings about a synchronic movement of the light source. Namely, either drawing or expanding the drape allows each first moving member to be restrained by the partition, so that the first moving member is able to be accurately positioned on the bracket of the drape. Therefore, the movement of the light source synchronizes with the movement of the first moving member to provide an even and enhanced lighting effect. When the light source is served at darkness or night, using convenience is further achieved.
