Multifunction Projector 2003-01-0553

Future AFS regulation will allow change of the low beam light distribution pattern. In order to propose AFS functions inside the headlamp, several approaches can be taken: combining multisource reflectors, or changing shields within a projector system. The first possibility requires many bulbs and dedicated reflectors that have a strong impact on cost and size. The second is a more compact solution with a projector system, using a rotating horizontal drum holding specific shields.
Such a design allows easy integration into the elliptical module, but generates constraints regarding accuracy of the positioning of optical components. Also, glare can be generated during transitory phases in between function changes.
