Abstract
A headlight unit includes a housing, a micro-LED device mounted in the housing, a relay lens system mounted in the housing forward of the micro-LED device, and a projection lens system mounted in the housing forward of the relay lens system. The micro-LED device has a plurality of forward-facing micro-LEDs, wherein first, second and third subsets of the micro-LEDs are arranged in respective first, second and third 2D arrays. The relay lens system includes first, second and third relay lenses configured to receive and relay respective first, second and third streams of light emitted by the first, second and third subsets of micro-LEDs. The projection lens system includes first, second and third projection lenses configured to receive and project the first, second and third streams of light in respective first, second and third projection patterns.
