Abstract:
A headlamp (10) for a motor vehicle has a first projection device (12) for illuminating a wide surface (18) and a second projection device (14) laterally offset from the first projection device (12) for illuminating a narrow surface (20) lying within the wide surface (18). Intensity profiles (22, 24) of light emitted by the first and second projection devices (12, 14) are matched in the lateral direction such that, in at least one lateral peripheral region of the narrow surface (20), a gradual transition to the intensity in the wide surface (18) outside the narrow surface (2) and a substantially constant intensity between the lateral peripheral regions of the narrow surface (20) within the narrow surface (20) occur. Intensity profiles (22, 24) of the projection devices (12, 14) are designed for a shorter distance than a projection distance designated for the wide surface (18) and the narrow surface (20).
