Abstract:
To provide a vehicular headlamp capable of suppressing the deterioration of visibility of an area ahead of a vehicle.SOLUTION: A vehicular headlamp 1 is equipped with a lighting unit 10, and a control portion CO to which a signal is inputted from a detection device 120 detecting an object located ahead of a vehicle 100. The control portion CO, when the object is not positioned ahead of the vehicle 100, controls the lighting unit 10 so as to emit light with a light distribution pattern PH of high beam, and when the object is positioned ahead of the vehicle 100, as compared with the case in which the object is not positioned ahead of the vehicle 100, controls the lighting unit 10 so as to decrease the light volume of the first areas 91a, 91b, and 91c overlapped with at least a part of the object, to increase the light volume of the second areas 92a, 92b, and 92c along at least a part of outer edges of the first areas 91a, 91b, and 91c, and to increase the light increasing volume of the second areas 92a, 92b, and 92c in proportion to the light decreasing volume of the first areas 91a, 91b, and 91c.SELECTED DRAWING: Figure 6
