Arranged in the reflection surface (11) of a paraboloid reflector (10) of motor vehicle headlamps is a segment (18) whose upper boundary edge (19) has the same focal length as the reflection surface (11), the focal length of the segment increasing linearly in the direction towards the lower boundary edge (20). The focal point (21) of the lower boundary edge (20) is situated in the first winding, facing the apex region (13) of the reflection surface (11), of the incandescent filament (24). The segment (18) generates the associated final components of the dipped beam to be emitted, so that the associated region (28) of the lens (26) is optically ineffective. <IMAGE>
