Motor vehicle headlamp has luminous intensity and lateral pivot control mechanisms for varying the luminous intensity distribution and lateral position of the lamp according to travel conditions

摘要

The headlamp has a unit pivot control mechanism (70) for laterally moving the luminous intensity distribution of a lamp unit by laterally pivoting the lamp unit (20), via a motor (72), according to the travel conditions of the vehicle, and a luminous intensity variable control mechanism (42) for varying the luminous intensity distribution by moving a shade (32) of the lamp unit according to the travel conditions of the vehicle. Beam emission can be carried out at emission angles with the luminous intensity distribution conforming to the travel conditions of the vehicle by properly combining beam emission control performed by the unit pivot control mechanism and the luminous intensity variable control mechanism. An Independent claim is included for a method of controlling the beam emitted from the vehicle headlamp.
