Abstract
Headlamp system for an automotive vehicle has an individual lamp for illuminating a high intensity zone and a spread zone of an image surface. The system includes a first light source having a substantially elliptical reflector for directing light to a spread light zone on an image surface and a second light source having a filament mounted in an axial direction to the length. A second reflector has a generally elliptical shape, a first focus, a second focus and a magnification. The second reflector directs light to a high intensity zone on the image surface. A light shield having a generally planar surface is mounted substantially normal to the longitudinal axis substantially at the second focus. An aspheric lens having an aperture having a width is located between the shield and image surface. The maximum magnification of the filament at the aspheric lens is substantially the width of the aperture.
