Abstract
A vehicular headlamp for emitting light with a predetermined light distribution pattern, includes a semiconductor light emitting element including a substantially linear light emitting area for generating the light therefrom, and an optical device for forming at least a part of a cut line to determine a boundary between bright and dark with regard to the light distribution pattern by reflecting or deflecting the light generated by the semiconductor light emitting element and projecting a shape of the light emitting area. The vehicular headlamp may further include a plurality of the semiconductor light emitting elements being arranged in a row in a direction corresponding to at least a part of the cut line, wherein the optical device forms at least a part of the cut line by projecting the shape of the light emitting area with regard to each of the plurality of semiconductor light emitting elements towards positions arranged in a row over at least a part of the cut line.
