Abstract

A vehicle headlamp may be formed from a light source; a divergent lens; and a reflector facing in a forward direction to the lens. The reflector has one or more first regions, and one or more second regions. The first region is a section of an ellipsoid of revolution with one focal point coincident with the light source, and one focal point located at the first focal point of the lens. The second regions have a surface with an elliptical vertical cross section having a first focal point coincident with the light source and a second focal point coincident with the first focal point of the lens. The second surface additionally has a horizontal axial cross section having a first focal point coincident with the light source and a second focal point axially offset from the first focal point of the lens. The horizontal axial cross section may be elliptical, parabolic or hyperbolic. Light from the first regions is convenient to form the beam hot spot. Meanwhile, light from the second regions is convenient to form the beam spread. In total the system provides a headlamp with a short axial dimension and a small frontal opening while meeting headlamp beam standards.
