ABSTRACT:
To provide for combined direct and indirect illumination of scenes or objs to be photographed or recorded, a halogen incandescent lamp (1) is positioned in a reflector which has two reflector portions (5, 6) having relative light output of, for example, 1:6. The reflector portions are obtained by forming cut lines (9, 10) parallel to a plane passing through the apex of the reflector and the lamp axis (A), the relatively larger reflector portion (6) being pivotably mounted in the housing. Reflective flaps (11) preferably depend from the relatively larger reflector portion (6) to provide for reflective surfaces adjacent the relatively smaller reflector portion (5) when the relatively larger portion (6) is pivoted away from the lamp axis (FIG. 3- A). A disk (4) may be placed in front of the larger reflector portion (6).
