Headlamp device for vehicle

摘要

A vehicle headlamp including a headlamp unit and an auxiliary lamp in which the brightness of an end portion of the low beam light distribution pattern formed by the beam irradiation from the headlamp unit is reinforced by the auxiliary light distribution pattern formed by the beam irradiation from the auxiliary lamp unit. The high luminous intensity area of the auxiliary light distribution pattern partly overlaps the high luminous intensity area of the low beam light distribution pattern, thus allowing the low beam light distribution pattern and the auxiliary light distribution pattern to be combined. Further, by way of controlling the beam irradiation intensity of the auxiliary lamp unit by a light control unit, the brightness of the low beam light distribution pattern is reinforced by the auxiliary light distribution pattern that has brightness in response to the vehicle running condition.
