Abstract
A vehicle headlamp has a unit pivot control mechanism for laterally moving the luminous intensity distribution of a lamp unit by laterally pivoting the lamp unit according to the travel conditions of the vehicle, and a luminous intensity variable control mechanism for varying the luminous intensity distribution by moving a shade 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. The result is improved visibility of a road surface ahead of the vehicle.
