发明名称 VEHICULAR HEADLAMP
摘要 PROBLEM TO BE SOLVED: To provide a vehicular headlamp capable of enhancing freedom of shape and luminous intensity distribution of a light distribution pattern while controlling deterioration of luminous intensity of the light distribution pattern due to reflection by a reflector.SOLUTION: In the vehicular headlamp, the movable shade 38 is installed movably between an advancing position and a prescribed retreat position. The movable shade 38, when it is in the advancing position, forms a low-beam light distribution pattern in which the upper portion than a cutoff line is cut off from a combined light-distribution pattern of a first light-distribution pattern by a first reflection surface 34a of a first reflector 34 and a second light-distribution pattern by a second reflection surface 36a of a second reflector 36. A light source installation part 16a has a light-emitting element 44 arranged at the lower part than an optical axis Ax. The first reflection surface 34a and the second reflection surface 36a are formed in non-continuation.
