Abstract
A sun protection device is described including at least one optically transparent dielectric layer, which on both sides is joined with a structural layer of an opaque or only partially translucent material. The two structural layers are structured subject to the formation of light passage openings and light-impermeable zones in such a manner that optical radiation incident on the outer structural layer under a predetermined angular range is blocked through interaction of the two structural layers and a proportion of optical radiation, which is incident on the second structural layer under a different angular range is able to pass the structural layers unhindered. The sun protection device makes possible an angle-selective transmission of sun radiation to achieve an anti-glare effect and at the same time allowing vision in a downward direction without moving parts.
