Abstract
A vehicle headlight device includes a light guide plate, a light source device and a light-pattern adjustment plate. A thickness of the light guide plate is gradually increased from a light incident side to a light reflection side, and the light reflection side is provided with a parabolic surface. The light source device is disposed to coincide with or be near a focus point of the parabolic surface. The parabolic surface reflects at least one light beam emitted from the light source device to allow the light beam to propagate in an alignment direction. The light-pattern adjustment plate has multiple grooves. The grooves are parallel to each other and arranged on a surface of the light-pattern adjustment plate facing the light guide plate, and a longitudinal direction of the grooves is different to the alignment direction.
