Vehicular headlamp and vehicle provided with same

A vehicular headlamp comprising:

• a reflector comprising a first reflective surface, and a shade region provided with a second reflective surface movable relative to the first reflective surface;
• and
• a light-source bulb disposed on a light axis of the first reflective surface, wherein
• the second reflective surface has a substantially parabolic shape and extends in substantially the same parabolic plane as the first reflective surface when the second reflective surface is at a neutral position, wherein
• the reflector is divided into two parts to be an upper reflector intersecting a reference plane including the light axis and a vehicle-transversely level line, and a lower reflector positioned below the reference plane, with a line region interposed between the upper reflector and the lower reflector, wherein
• the upper reflector is configured to have the first reflective surface and the shade region, light from the light-source bulb reflected therefrom being provided to the vehicle as a reference light-distribution pattern for low beam defined with a cut line formed by the line region, and
• the lower reflector is configured to have the second reflective surface, light from the light-source bulb reflected therefrom being provided as a dispersed light-distribution pattern for low beam relative to the reference light-distribution pattern, the lower reflector being rotatable about a vertical axis vehicle to a focus of one of the first and second reflective surfaces.
