Device for automatic main and dipped beam regulation for motor vehicles derives required head lamp setting between main and dipped beam from intensity of frontally incident light

摘要

The device measures the light incident on the vehicle (5) from the front with a light sensor and automatically computes the required head lamp setting between main and dipped beam. The light sensor is an exposure meter that computes the incident light intensity from a defied angular range (1) with the aid of an objective.
