  • Lighting device for vehicles
    Patent number: 9772081
    Abstract: A lighting device for vehicles with a semiconductor-based light source and an optical unit having an imaging device for producing a predetermined light distribution and having an optical element arranged between the semiconductor-based light source and the imaging device. The optical element has a back side facing the semiconductor-based light source and has a front side facing the imaging device. The optical element is formed as a color correction element which has a color correction-free partial surface area through which a firstly emitted partial light beam of the semiconductor-based light source passes and has a color correction-affected partial surface area through which the secondly emitted partial light beam of the semiconductor-based light source passes in a border angle area.
    Type: Grant
