MOTOR VEHICLE HEADLAMP WITH CONCAVE MIRROR REFLECTORS

摘要

A motor vehicle headlamp comprising a first semiconductor light source and a first concave mirror reflector, a second semiconductor light source and a second concave mirror reflector, and a third semiconductor light source and a third reflector. Each semiconductor light source includes at least two separate semiconductor chips. The second semiconductor light source includes a first group of semiconductor chips and a second group of semiconductor chips, and a control circuit, which operates either the first semiconductor light source without the third semiconductor light source, or the third semiconductor light source without the first semiconductor light source, operates at least a first portion of the semiconductor chips of the second semiconductor light source together with the first semiconductor light source, and operates at least a second portion of the semiconductor chips of the second semiconductor light source together with the third semiconductor light source.
