Abstract
An adaptive beam scanning headlamp for a vehicle includes a plurality of light sources arranged linearly, with each of the plurality of light sources having a linear array of LEDs. A plurality of primary projection lenses shape light from the plurality of light sources. An oscillating mirror obliquely angled between the plurality of primary projection lenses and a secondary projection lens receives light from the plurality of primary projection lenses and redirects the light to the secondary projection lens. The secondary projection lens is adapted to further shape the light for projecting a beam pattern from the vehicle. A controller is adapted for controlling each of the plurality of light sources and the oscillating mirror to actively dim or turn off portions of the beam pattern for reducing glare perceived outside the vehicle.
