The invention provides a meeting lamp optical element for generating halo combined patterns and a design method thereof. The meeting lamp optical element is an optical array spaced from an irradiating surface by a preset interval range; the optical array consists of multiple optical modules; the optical modules include light sources and circular halo generation lenses; sub light sources are point light sources; lighted surfaces of the halo generation lenses of all the optical modules are positioned on the same one plane; emitting light rays of the sub light sources are refracted by the halo generation lenses to generate circular light spots on the irradiating furnace; and when relative positions of the sub light sources and optical axes of the halo generation lenses are changed, the positions of the circular light spots generated by the optical modules on the irradiating furnace are changed, so that circular light spot patterns generated by all the optical modules are combined with each other. The meeting lamp optical element can use a similar Fresnel refracting optical element for generating halo patterns on the irradiating surface, and can combine the generated halo patterns through adjusting the positions of the sub light sources to form four-ring patterns like the Audi trademark on the irradiating surface.
