  • Patent number: 6146004
    Abstract: A vehicle lamp has a housing, a light-transmissive shield covering the housing that extends across a corner area of the vehicle, at least one lamp chamber in the housing in which a light source is positioned, and a Fresnel lens having concentrically arranged prism rings located between the light source and the light-transmissive shield adjacent to the light-transmissive shield in at least partial area. The Fresnel lens has at least one curved partial area, in order to make manufacturing as simple as possible while achieving an optimal illumination and maintaining proper light distribution. The Fresnel lens is comprised of a first curved partial area having a center of the concentrically arranged prism rings and a second partial area extending up to a side area of the lamp chamber. The partial areas have differing surface geometries and are separated from each other by vertical separating lines.
