Abstract

A sunlight manipulating device includes a light focusing module and a light deflection module. The light focusing module is configured for converging incident sunlight on a focal region. The light deflection module is arranged on the focal region or adjacent to the focal region and configured for deflecting the converged sunlight to a target area, wherein the target area is diverged from an optical axis of the light focusing module. The above-mentioned sunlight manipulating device allows more diverse configurations for solar cells, heating devices and light guide elements or the like means.
