Zusammenfassung:A condenser lens and a headlamp assembly employing the condenser lens improves control over the beam spread characteristics, while at the same time reduces the package size of the headlamp assembly. The condenser lens is provided for a projector-type headlamp assembly having a light source emitting light which is projected longitudinally downstream in front of a motor vehicle. The condenser lens generally includes a main body of light transmitting material. The main body defines a first surface receiving light from the light source and a second surface emitting the light. The second surface has at least one facet structured to spread the light and provide a predetermined beam pattern.
