Abstract

487,141. Reflectors. HOLZER; G., (trading as WALDMANN & BRUDER, M.), STROHMEIER, H., and STROHMEIER, E. Jan. 29, 1938, No. 2912. Convention date, Nov. 30, 1937. [Class 75 (ii)] A light projector, more particularly for motor vehicles, has a reflector formed in the main as a curved surface of rotation (portions 1, 3 and 5) but having two zones 2 and 4 whose cross sections are elongated, for example, ellipses, the zone 2 nearer the central portion 1 having its major axis vertical and the other having its major axis horizontal. One or more further pairs of elongated zones may be provided.
