Motor vehicle headlamp having a multi-function projection module

摘要

A motor vehicle headlamp (10) including a multi-function projection module (14), which is designed to convert light from a first light source (16) into a first light distribution (34) by means of a first primary lens system (18) in a first beam path bounded by an aperture edge (26), and to focus light from a second light source (20) into a beam waist (44) and convert the light into a second light distribution by means of a second primary lens system (22) in a second beam path. The second light distribution has a predetermined central point (56). The projection module includes a mirror (30), which is arranged in the second beam path between the beam waist (44) and the projection lens (28) in such a way that the mirror produces a virtual mirror image of the beam waist (44) at the focal point of the projection lens.

主权项

1. A motor vehicle headlamp having a multi-function projection module, said headlamp comprising:
a first light source, a first primary lens system, a second light source, a second primary lens system, an aperture having an aperture edge, a projection lens having an optical axis, and a mirror being reflective, and wherein each of the first and second light sources is oriented to face the projection lens; the first primary lens system being configured to transfer light of the first light source in a first beam-path being restricted by the aperture edge such that the first-beam path is restricted to be above the optical axis and into a first light distribution area located in front of the projection module; the second primary lens system being configured to focus light of the second light source in a second beam-path into a beam waist and to transfer the light into a second light distribution area located in front of the projection module; the second light distribution area includes a predetermined central point, which when the headlamp is used according to its intended purpose, lies at an intersection point of a horizontal line H=0 and a vertical line V=0 in front of the vehicle in the manner predetermined by the lighting standards for motor vehicles; and wherein the mirror is arranged in the second beam path such that the mirror is configured to reflect the light in second beam path such that the second beam path is restricted to be below the optical axis and wherein the mirror is disposed between the beam waist and the projection lens such that the mirror is configured to generate a virtual reflection of the beam waist that surrounds the predetermined central point of the second light distribution area through an image conveyed by the projection lens.
