Abstract
An adaptable-driving-beam headlamp for a vehicle includes a plurality of light-emitting diodes (LEDs) mounted on one or more printed circuit boards. An inner lens assembly has a plurality of discrete sub-lenses. Each discrete sub-lens of the inner lens assembly is aligned with a respective one of the plurality of LEDs for shaping emitted light. An outer lens is adapted to receive light from the inner lens assembly and project the light from the vehicle. A camera system for imaging a forward view from the vehicle. A controller is adapted for determining a target location based images received from the camera system such that dimming of one or more LEDs via the controller reduces glare from the vehicle adaptable-driving-beam headlamp as perceived at the target location.
