LENS UNIT, AUXILIARY LOW-BEAM MODULE, LENS, LOW-BEAM ILLUMINATION MODULE AND VEHICLE

WIPO Patent Application WO/2022/001657

A1

A lens unit, a lens for a low-beam illumination module, a low-beam illumination module and a vehicle. The lens unit comprises a rear surface (21) and a front surface (22); the lens unit has a focal line (23), and the focal line (23) is a straight line perpendicular to a light emitting direction of the lens unit; the rear surface (21) and the front surface (22) are adapted to project light rays passing through the focal line (23) into parallel light rays, and the front surface (22) is a free-form surface. The lens unit has the optical characteristics of a cylindrical lens, and is able to cause parallel incident light to be focused into a line instead of a focal point upon passing through the lens unit, so that even though a light emitting surface, i.e. the front surface (22), of the lens unit is a free-form surface extending obliquely in the vertical direction, as long as the focal line (23) is a straight line perpendicular to the light emitting direction of the lens unit, an illumination light shape complying with the requirements of vehicle lamp regulations can be achieved, and a light emitting effect is not affected by the obliqueness of the front surface (22).
