VEHICULAR HEADLAMP DEVICE

A vehicular headlamp device includes a pair of lamps (LHi, RHi), a light illumination region (PLHi) of one of which is divided into a plurality of zones (VZ) in one direction, and a light illumination region (PRHi) of the other of which is divided into a plurality of zones (HZ) in a direction crossing the one direction, and a control unit (ECU) configured to control the illumination light quantity of each of the zones. The vehicular headlamp device is configured to obtain a required light distribution pattern (PHi) by superposing the light illumination regions (PLHi, PRHi) of the pair of lamps (LHi, RHi).
