    摘要: A vehicle headlamp module, including an electrical circuit arrangement for controlling at least one function of a vehicle headlamp, and a housing for at least partially accommodating the electrical circuit arrangement, wherein the housing at least in certain sections has a metallic electrically conductive shielding surface facing the circuit arrangement for electromagnetically shielding the circuit arrangement. The electrical circuit arrangement has at least one contact-sensitive surface section that is constructed in a substantially planar manner, is free from electrical components arranged thereon, and faces a planar section of the shielding surface of the housing. Electrical conductor tracks and/or contacts run along the contact-sensitive surface section, wherein a number of cured electrically non-conductive adhesive dots is arranged on the contact-sensitive surface section that is constructed in a substantially planar manner, which protrude from the contact-sensitive surface section in the direction of the planar section of the shielding surface of the housing to ensure a minimum spacing between the contact-sensitive surface section and the planar section of the shielding surface of the housing.

    摘要: An optical system for a motor vehicle headlight, wherein the system includes at least two optical elements, including a light coupling area, a light decoupling area, a lateral surface which delimits the optical element and which has an optically effective aperture edge for forming a bright/dark boundary in a far-field light distribution producible with the optical system. The optical system includes at least two anterior optics, wherein an anterior optic is associated with each optical element, wherein a first anterior optic is configured to direct light beams along a first coupling direction onto the light coupling area of the optical element associated with it. A second anterior optic is configured to direct light beams along a second coupling direction onto the light coupling area of the optical element associated with it, wherein the first anterior optic and the first optical element are configured to produce a first far-field light distribution, wherein the second anterior optic and the second optical element are configured to produce a second far-field light distribution, which lies below the bright/dark boundary of the first far-field light distribution.
