Abstract
At least a part of light emitted from a light source passes through a projection lens. A rotary shade is disposed at the rear side of the projection lens to block a part of the light emitted from the light source. The rotary shade includes a twist end surface. A swivel actuator changes an optical axis direction of the projection lens. A shade driving mechanism rotates the rotary shade around the rotary axis. A first information acquisition unit acquires first information on a rudder angle of the vehicle. A second information acquisition unit acquires second information on the front area of the vehicle. A first control unit controls the swivel actuator to determine the optical axis direction based on the first information. A second control unit controls the shade driving mechanism to determine the position of the twist end surface based on the second information.
