ABSTRACT:
A photographic lamp possessing a main and back-reflector which are located respectively behind and in front of a light source. The main reflector limits a light exit aperture which is closed by a diffuser screen. The back-reflector comprises a transparent base which is partly provided with a reflecting layer. The reflecting layer is preferably applied in the manner of a graduated filter, so that the reflecting points are more numerous in the center of the base and less frequent at its periphery. The light produced is thereby extremely even and the illumination is very even, avoiding dark areas on the diffuser screen.
