Abstract

Procedure for obtaining a new dipped beam for vehicle projectors from a lamp designed for the realization of the current unified European dipped beam as defined in the Highway Code, characterized in that it consists of tilting the lamp of the projector at a certain angle relative to the axis of the reflector of said projector, so that the intersection line of the dipped beam is modified until it is locally approached, thanks to a simple geometric transformation, to the desired cut shape; simultaneously, in subjecting the lamp to a rotation around the axis of its crossing filament or any parallel axis and close to it, in relation to its normal position of use, so that it is situated, approximately along a horizontal line, the line of cut that is on the side opposite the direction of circulation for which the projector is intended; and in introducing, at the path followed by the beam emitted by the lamp thus arranged in the vicinity of the reflector focus, at least one deviator device, so that it cuts, on the side of the direction of circulation for which it is provided for the projector, its final shape that meets the specifications of the new dipped beam defined by draft international regulation No. X 90.
