Abstract

999,634. Vehicle headlamps. SOC. ANON. LAMPE NORMA SOC. AUTO LAMPE. May 10, 1962 [May 10, 1961], No. 18015/62. Heading F4R. The reflector of a vehicle headlamp comprises two substantially parabolic parts M 1 , M 2 , the foci F 1 , F 2 of which and the poles of which are offset in the direction of the reflector axis X,X<SP>1</SP> and a further substantially parabolic mirror M 3 rotatable about the axis X, X<SP>1</SP> through a gap between the parts M 1 , M 2 from a position behind the part M 2 into a position in front of the part M 1 , an incandescent body S being arranged transversely to the axes X, X 1 so that the focus F 3 of the mirror M 3 coincides with part at least of the body S.
