Description

Technical Field

[0001] The utility model relates to the technical field of automotive lighting, in particular to a large-inclination thin lens module. Background Technique

[0002] The styling design of automotive headlights is also more artistic, and the trend of exaggerated and bold styling constantly challenges the capabilities of headlight designers. On the premise of ensuring that each function of the headlight meets the regulatory requirements, the inclination angle of the headlight styling is getting larger, the opening is getting smaller, and the design difficulty is constantly increasing. The early automotive headlight projection modules were mainly designed to meet functions and had no styling. For example, the initial designs of bulbs and LED projectors were generally spherical lenses, which occupied a large space and had a single shape, making it impossible to carry out styling design. In recent years, the design schemes of narrow modules have emerged in large numbers. However, when the outer lens or styling of the headlight or headlight module is at a large angle and inclined, the lens module structure is relatively complex and the lens thickness is relatively thick, and it will have a certain impact on the light pattern with the need for broadening. Therefore, we need to propose a large-inclination thin lens module. Content of the Utility Model

[0003] The purpose of the utility model is to provide a large-inclination thin lens module, which can further improve the large-angle inclination setting of the lens module, ensure excellent optical performance, reduce the number and complexity of lenses, avoid a relatively thick lens thickness, save the front and rear space sizes of the optical device, and ensure that the light pattern with the need for broadening is not affected, so as to solve the problems proposed in the above background technique.
