ABSTRACT:
A lamp unit includes a semiconductor light-emitting element portion, a reflector that radiates light from a light source forward of the lamp, and a driving portion that moves relative positions of the semiconductor light-emitting element portion and the reflector. The semiconductor light-emitting element portion is provided with a light-emitting surface whose outer peripheral shape is generally oblong, the reflector is provided with a parabolic surface that has a focus line in the horizontal direction, and the driving portion is configured such that rotation is possible within a horizontal plane of the light-emitting surface from a first position where a short side of the light-emitting surface is generally parallel to the focus line up to a second position where a long side of the light-emitting surface is generally parallel to the focus line.
