Abstract

Studio lights have high light loading and large radiant surfaces with a reflector trough and at least one high load flash tube having a cover device to prevent the direct emission of radiant light, has the cover (3) manufactured such that it is partially light transmitting. The light transmitting character of the direct emission prevention cover (3) is such that it decreases continuously from the outer edge towards the centre of the cover. The cover is constructed such that it has concentric rows of holes (4, 5, 6) with the number of holes per row decreasing from edge to centre of the cover (3).
