Abstract
Particular embodiments may provide for a method of providing illumination for a vehicle. A user input related to controlling a headlamp assembly for a vehicle may be received. The headlamp assembly may comprise a laser-based lamp positioned to provide high-beam illumination, including a plurality of beam subfields, and a light sensor configured to capture images of objects illuminated by the headlamp assembly. Instructions to activate the headlamp assembly may be sent. Images of a scene illuminated by the headlamp assembly may be captured. An object of interest in the images of the scene may be detected. The detected objects may be identified as a traveling vehicle moving along a path in a beam field of the lamp. Instructions to dim light emitted by the laser-based lamp within at least one subfield of the beam field may be sent. The subfield may correspond to a location of the traveling vehicle.
