A vehicle headlamp is provided with: a fixed reflector (3) having reflecting surfaces (2U,2D), a respective one of which is made of a parabola-based free curved face; movable reflectors (13U,13D) having reflecting surfaces, a respective one of which is made of a parabola-based free curved face; and semiconductor-type light sources (5U,5D), a respective one of which has a light emitting chip shaped like a planar rectangle. When the movable reflectors (13U,13D) are positioned in a first location, a light distribution pattern for low beam is obtained on the reflecting surfaces of the fixed reflector. When the movable reflectors are positioned in a second location, light distribution patterns for high beams are obtained on the reflecting surfaces of the fixed reflector and the movable reflector. As a result, the vehicle headlamp enables downsizing, weight reduction, power saving, and cost reduction. |
