VEHICLE HEADLAMPS
Document Type and Number:
WIPO Patent Application WO/2022/168926
Kind Code:
A1
Abstract:
Vehicle headlamps (20) comprise a right-side lamp (40), a left-side lamp (40), and a control unit (110). A right-side light distribution pattern (430) and a left-side light distribution pattern (450) each include an overlapping area (471) and a non-overlapping area (473). If a steering angle is greater than a prescribed angle, the control unit (110) controls power supplied to light-emitting parts in the right-side lamp and power supplied to light-emitting parts in the left-side lamp such that: a first area in a first light distribution pattern is located in the non-overlapping area (473) in the first light distribution pattern; a second area in a second light distribution pattern is located in the overlapping area (471); and a first intensity of light in the first area becomes greater than the sum of a second intensity of light in the second area and a third intensity of light in an area overlapping with the second area within the first light distribution pattern.
