Abstract:
A vehicle headlamp is provided with a projection lens, a light source, a reflector, a first shade, and a second shade. The first shade includes an upper end crossing in a vicinity of a rear side focal point of the projection lens. The first shade shields a part of the light emitted from the light source and reflected by the reflector to form a first light distribution pattern. The second shade includes a light shielding portion for shielding a part of the light emitted from the light source and reflected by the reflector to form a second light distribution pattern. The second shade is movable between a first position and a second position. In the first position, the second shade is positioned above the first shade and is separated from the first shade so that the first light distribution pattern is formed. In the second position, the second shade covers the upper end of the first shade so that the second light distribution pattern is formed.
