Improved Low Beam by Use of Segmented Headlamp Systems

This report gives an overview of the current status of developments intended to improve the low beam of motor vehicle headlamp systems by use of segmented reflectors.

In addition to advantages in terms of lighting technique (gain in luminous flux, increasing safety for the driver as a result of improved lateral illumination level and foreground brightness), the segmented reflector also accommodates the stylistic wishes of the automobile manufacturers (smaller overall height, larger angle of inclination of the lens), and thus represents a genuine alternative to the Polyellipsoid headlamp (PES) for the future.

The advantages will be explained and quantified using concrete examples.
