A vehicle headlamp (1) is provided with a light emitting unit (10), a determination unit (25), and a control unit (CO). When a signal indicating another vehicle (80, 90) is input, the control unit (CO) controls the light-emitting unit (10) so that a region including the first region (211, 311) in the light distribution pattern (200, 300) becomes a light-reducing region (210, 310) in which the total beam amount of light from the light-emitting unit (10) is reduced than before the signal indicating the other vehicle (80, 90) is input, and the light-reducing region (210, 310) becomes a light-reducing region (210, 310) in which the total beam amount of light from the light-emitting unit (10) before the signal indicating the other vehicle (80, 90) is input. When a signal indicating a turning advance notice of another vehicle (80, 90) is input, the light-emitting unit (10) is controlled so that at least a first region (211, 311) in the dimmed region (210, 310) expands toward the turning direction indicated by the turning advance notice than before the signal indicating the turning advance notice of the other vehicle (80, 90) is input.

    车辆用前照灯(1)具备发光单元(10)、判定部(25)、以及控制部(CO)。就控制部(CO)而言,在被输入表示其他车辆(80、90)的信号的情况下,控制发光单元(10),以使配光图案(200、300)中包含第一区域(211、311)的区域成为比输入表示其他车辆(80、90)的信号之前减少了来自发光单元(10)的光的总光束量的减光区域(210、310),在被输入表示其他车辆(80、90)的转弯预告的信号的情况下,控制发光单元(10),以使减光区域(210、310)中至少第一区域(211、311)相较于输入表示其他车辆(80、90)的转弯预告的信号之前,向转弯预告表示的转弯方向侧扩展。
