A DEVICE FOR AUTOMATIC SELECTIVE LIGHT CONTROL FOR VEHICLES

摘要

A device for automatic and selective light control of the headlights of vehicles is provided with a light sensitive detector that detects the distribution/intensity of light in the area in front of the vehicle. By the aid of a control unit said detector controls the light distribution pattern of the headlights of the vehicle in accordance with the distribution of the detected light. The headlights of the vehicle can be provided with intersecting directions of the axes of light beams. In this manner efficient dimming of the light may be achieved selectively in the areas where there are other vehicles, persons, or sources of light, whereas a maximum satisfactory illumination is maintained of the roadway in front of the vehicle.
