Document Type and Number:
WIPO Patent Application WO/2023/201573
Kind Code:
A1
Abstract:
An optical element, a vehicle light module, a vehicle light, and a vehicle. The optical element comprises a plurality of optical units. Each optical unit comprises a light incident surface (11), a light guide part (12), and a light-emitting surface (13). The light incident surfaces (11) are located on the same plane and are successively connected so as to form an optical element light incident surface. The light guide parts (12) are arranged such that light rays emitted from the optical element light incident surface can be guided so as to be emitted from the corresponding light-emitting surfaces (13). The light-emitting surfaces (13) are arranged in a preset form. The optical element is provided with the light-emitting surfaces (13) having a smaller width dimension, therefore is suitable for elongated vehicle lights of different sizes, and has the advantages of a high integration level, high optical efficiency and a small size.
