Patent ID: 7156544

Claim:
A vehicle headlamp configured to form a light distribution pattern by light radiation from at least one lamp unit comprising: at least one semiconductor light-emitting element as a light-source; a projection lens disposed on an optical axis extending in a longitudinal direction of a vehicle; and a first light-source unit and a second light-source unit each disposed rearward of the projection lens, wherein, the first light-source unit comprises: a first semiconductor light-emitting element facing substantially upward on a first reference axis extending substantially in the longitudinal direction; a first reflector configured to reflect light from the first semiconductor light-emitting element forward and substantially near the first reference axis to substantially converge the reflected light substantially near a rear focal point of the projection lens; and a forward travel blocking member extending rearward from substantially near the rear focal point to prevent the light reflected by the first reflector from traveling forward, the second light-source unit comprises: a second semiconductor light-emitting element facing substantially downward on a second reference axis extending substantially in the longitudinal directions; and a second reflector configured to reflect light from the second semiconductor light-emitting element forward and substantially near the second reference axis to substantially converge the reflected light substantially near the rear focal point, and when the first light-source unit is illuminated a low-beam light distribution pattern having cut-off lines at an upper end portion as reverse projection images of a front edge of the forward travel blocking member is formed, and a high-beam light distribution pattern spreading upward from the cut-off line is formed upon illumination of the second light-source unit.
