Abstract
Systems and methods for generating light distributions on roadways with motor vehicle headlights having at least one laser light source which is modulated by an actuator and a processing unit and of which the laser beam is directed onto at least one light conversion element via a beam deflection element actuated by a beam deflection actuator, said light conversion element having a phosphor for converting light, and said headlight also comprising a projection system for projecting the light image generated at the at least one light conversion element onto the roadway, wherein in addition to changing a specified light distribution, the processing unit is configured to change the intensity of the beam of the laser light source by the actuator according to a specified function in the sense of increasing the intensity in the direction of the edges of the light image generated on the light conversion element.
