Problems solved by technology

[0004] However, the lighting shape of car lights has anisotropic requirements, such as small up and down lighting angles and large left and right lighting angles; for this reason, the car light lighting system based on the above-mentioned collimating lens needs to form a foundation with a certain width through an additional optical system The light shape is then imaged to the road surface through the collimating lens, making the structure relatively complex

Abstract

The invention relates to a vehicle optical element, and discloses an optical lens which comprises a light inlet part and a light outlet part. A first single-direction straightening surface (1) is formed on the light inlet part, a second single-direction straightening surface (2) is formed on the light outlet part, the straightening direction of the first single-direction straightening surface (1) is perpendicular to the straightening direction of the second single-direction straightening surface (2), and the first single-direction straightening surface (1) and the second single-direction straightening surface (2) jointly form a focal point or a focusing area of the optical lens. The invention further discloses an optical lens group, a vehicle lamp system and a vehicle. The optical lens can meet the requirement for anisotropy of the lighting light shape of a vehicle lamp, and an asymmetric light shape is formed.

Description

technical field [0001] The present invention relates to vehicle optical components, in particular to an optical lens. Furthermore, it relates to an optical lens assembly, a vehicle lighting system with the optical lens or the optical lens assembly, and a vehicle with the vehicle lighting system. Background technique [0002] Car light refers to the lamps on the vehicle. It is a lighting tool for vehicles driving on the road at night, and it is also a prompt tool for sending out various vehicle driving signals. It plays a very important role in ensuring the safe driving of vehicles. With the development of social economy, the automobile industry also develops accordingly. With the continuous development of automobile lighting technology, more requirements are put forward for the functions of car lights. [0003] In the lighting module that realizes the lighting function of the car lamp, collimating optical elements are usually set to obtain approximately parallel outgoing ra...
