Abstract:
A vehicle headlamp includes: a lamp outer casing; a lamp unit including: a light source unit having a light source that emits light, a reflector and a heat sink; a stationary frame; a movable frame that is supported by the stationary frame to be rotatable about a rotating shaft; a lens unit supported by the movable frame and having a projection lens; a first aiming operation shaft that adjusts an optical axis in the lateral direction; and a second aiming operation shaft that adjusts the optical axis in the vertical direction. A focal point of the light reflected by the reflector is coincident with a center of the rotating shaft. The lens unit is moved relative to the stationary frame such that a distance between the focal point and the projection lens is constant. The heat sink is positioned on the outside of the lamp outer casing.
