Abstract: A light-reflecting device incorporates a central light-reflecting frame (10) of polygonal shape fitted with a cross bar (17) carrying at the centre a universal joint assembly (24) one element (21) of which is fixed to the cross bar (17) and the other relatively movable element (29) is formed for attachment to a supporting rod (25) and there are provided adjacent each end of the cross bar (17) a universal joint assembly (20) one element of which is fastened to the cross bar and the other relatively movable element (21) of which is attached to an edge of a respective outer light-reflecting frame (10) also of polygonal shape. In use the frames may be swung to an infinite number of positions and configurations to provide in conjunction with a given light source any desired lighting conditions. The device is also readily dismantled for easy portability.
