Abstract
A lens structure includes a lens body; an outer surface of the lens body is provided as a single curved surface; and an inner surface of the lens body is provided thereon with at least two inner curved surfaces that are continuously connected. In the present solution, through the design of the plurality of inner curved surfaces, the light pattern and the energy distribution can be controlled flexibly, the applicability of the lens design is maximally greatly improved, and meanwhile, a truly feasible solution is provided for the defect where in some scenes it is impossible for the existing conventional structure to distribute light. In addition, multiple functions may be implemented at the same time, such as, low beam, high beam, bending and fog lamp; and multiple functions are combined into one lens module for implementation.
