Document Type and Number:

WIPO Patent Application WO/2022/110760

Kind Code:

A1

Abstract:

A high-beam optical element, a high-beam lighting unit, a vehicle lamp and a vehicle. The high-beam optical element comprises a light incident part (1), a light guide part (2) and a light emergent part (3), which are arranged from back to front, wherein the light incident part (1) comprises a high-beam light incident part (11) and an auxiliary illuminating light incident part (12); the light guide part (2) comprises a high-beam light guide part (21) arranged corresponding to the high-beam light incident part (11), and an auxiliary illuminating light guide part (22) arranged corresponding to the auxiliary illuminating light incident part (12); the high-beam light guide part (21) is integrally connected to the high-beam light incident part (11); the auxiliary illuminating light guide part (22) and the auxiliary illuminating light incident part (12) are independently arranged; a front end face of the auxiliary illuminating incident part (12) forms an auxiliary light emergent face (13), and a rear end face of the auxiliary illuminating light guide part (22) forms an auxiliary light incident face (23); and light received by the auxiliary illuminating light incident part (12) is emitted via the auxiliary light emergent face (13), is then transmitted to the light emergent part (3) by means of the auxiliary illuminating light guide part (22), is totally reflected in the light emergent part (3) to form diffuse reflection, and is emitted from a light emergent face to form auxiliary illuminating light. The high-beam optical element can illuminate the vehicle lamp and has a simple structure.
