Abstract
An automotive adaptive driving beam (ADB) headlamp (20) includes a housing (22), a digital camera (32), an ADB controller (28), a segmented lighting array (24), and an ADB driver (30), wherein the digital camera (32) is integral with the ADB headlamp (20). The housing (22) includes an attachment structure (34) for attachment to a vehicle headlamp cavity (15). The digital camera (32) captures an image preceding the vehicle (2) and the ADB controller (28) detects an object (48) in the image and generates a control signal based, at least in part, on a position of the object (48). The segmented lighting array (24) is disposed within the housing (22) and includes a plurality of solid-state light sources (40a-n) arranged to emit a light in a light distribution pattern (26). The ADB driver (30) selectively drives the solid-state light sources (40a-n) based on the control signal from the ADB controller (28).
