Abstract:
An automotive lamp optical element, relating to the technical field of automotive headlamp illumination, and comprises a plurality of light condensation elements. Each light condensation element comprises a light inlet part (101), a light transmission part (102), and a light outlet surface which are connected in sequence, and the light outlet surfaces of the light condensation elements are connected with one another or integrally form a light outlet part (104); at least one pair of light condensation elements are arranged vertically, and the light inlet parts (101) of the pair of light condensation elements are connected to the same light transmission part (102); an included angle in the vertical direction is formed between the optical axis of at least one light inlet part (101) in the two light inlet parts (101) and the optical axis of the light outlet part (104), and the light inlet part (101) inclines towards a light emergent direction. An automotive lamp lighting module, an automotive lamp, and a vehicle. The illumination intensity at a local position of the emergent light shape can be enhanced, and light emitted by a light source can be collected more efficiently.
