  • Patent number: 11067725
    Abstract: The embodiments of the invention provide a multi-focal collimating lens and a headlight assembly for an automotive low beam. The multi-focal collimating lens includes a central collimating lens portion and two total internal reflection lens portions arranged on a left side and a right side of the central collimating lens portion. The central collimating lens portion and the total internal reflection lens portions share two focal points symmetrically located on both sides of a vertical symmetry plane of the multi-focal collimating lens. An upper edge and a lower edge of the multi-focal collimating lens are formed based on the two focal points, so that the headlight assembly is able to generate a cut-off line of the automotive low beam in a far-field light pattern of the multi-focal collimating lens.
