摘要

A solar energy collector includes a frustoconical reflective shell and a light converging lens. The frustoconical reflective shell includes a top opening and an opposite bottom opening. The reflective shell tapers from the top opening to the bottom opening. The reflective shell is configured for reflecting light. The light converging lens is arranged at the top opening and is fixed on the sidewall of the reflective shell. The light concentration lens includes a central lens portion and a periphery lens portion. The central lens portion includes a first light incident portion facing away from the bottom opening. The central lens portion includes a plurality of concentric annular prisms cooperatively forming a Fresnel-lens structure. The periphery lens portion is arranged surrounding the central lens portion. The periphery lens portion includes a convex second lens portion.
