[0002] In the field of automotive lighting, automotive LED dual-beam modules are key components that play a vital role in improving vehicle driving safety. They need to accurately switch and optimize between low beam and high beam lighting modes to meet the lighting needs of different driving scenarios.

[0003] In traditional technology, automotive LED bi-xenon modules typically use glass lenses for both the low-beam and high-beam lens assemblies to focus and project light, thus achieving the desired low-beam and high-beam illumination. Thanks to their excellent optical properties, glass lenses can, to a certain extent, ensure the direction of light propagation and focusing accuracy, allowing the low-beam and high-beam to illuminate the road surface as intended, providing the driver with a clear view. However, this design using glass lenses has significant limitations: glass itself has a high density, resulting in a significant increase in the overall weight of the bi-xenon module equipped with glass lenses; moreover, glass lenses occupy internal space in the headlight, affecting the vehicle's lightweight design; and the presence of glass lenses undoubtedly increases assembly steps. Utility Model Content

[0004] The purpose of this invention is to provide an automotive LED dual-beam module that can reduce the overall weight of the dual-beam module, ensure lightweight vehicle design, and reduce lens assembly steps.

[0005] To achieve the above objectives, this utility model provides the following solution:
