The invention relates to a portable light manipulator. Such a portable light manipulator is described in the form of a light reflector e.g. in EP 0 597 199 A1. The required force for fastening the cross member to the longitudinal members during assembly is considerable, however. The aim of the invention is to provide an improved portable light manipulator that is both easier to operate and allows higher tolerance with respect to the cloth tension and counteracts the reduction of said tension due to aging effects. The aim of the invention is achieved by means of a light manipulator, consisting of a frame and a manipulator cloth (1) that is stretched or can be stretched on the frame, wherein the frame comprises at least one tension bar (3), which has at least two moving sections (9, 13) that can be moved in the longitudinal direction of the tension bar and are connected to one another or can be connected to one another, said moving sections being spring-loaded so as to be capable of being forced apart from one another by spring force in the longitudinal direction of the tension bar. |
