| description | The invention relates to the field of illumination, and discloses a condensation Fresnel lens, a preparation method thereof and a mirror surface base. Convex lenses are symmetrically arranged on the central axis of the top of the mirror surface base, and a plurality of Fresnel convex teeth are sequentially arranged on the peripheries of the convex lenses; each Fresnel convex tooth comprises an extreme value surface close to the central shaft and a light emitting surface far away from the central shaft; the extreme value surface and the light emitting surface are sequentially connected end to end; the extreme value surface is a plane, and second refracted light rays taking the intersection point of the extreme value surface and the light emitting surface as a second refracting point coincide with the extreme value surface; and due to the slope of each point of the light-emitting surface, each beam of light is refracted by the condensing Fresnel lens and then is emitted in parallel to the central axis.
