Abstract
A motor vehicle headlight with a reflector consisting of two partial paraboloids arranged one above the other, which have at least approximately a common axis and of which the focus of the upper partial paraboloid is located closer to the apeces of the two partial paraboloids; a first filament for the low beam is located between the two foci of the two partial paraboloids while a second filament for the high beam is located in the focus of the lower partial paraboloid; the light emitted by the high-beam filament in the direction toward the upper partial paraboloid is shielded by a covering arranged on top of the high beam filament.

A motor vehicle headlight, comprising a reflector means including two partial paraboloids arranged one above the other, the focus of the upper partial paraboloid being located closer to the apeces of the two partial paraboloids, a first filament means for producing a low beam, said first filament means being located between the two foci of the two partial paraboloids, and a second filament means for producing a high beam, said second filament means being located substantially within the focus of the lower partial paraboloid, characterized by a covering means for shielding the light emitted by the second filament means in the direction toward the upper partial paraboloid whereby near-field illumination by the high beam is avoided.
