A glazing unit is provided for producing an aesthetically pleasing effect. The glazing unit may include at least one polymer with a first structured surface to which a photonic structure is applied. The surface can reflect a first partial spectrum of incident electromagnetic radiation, and can transmit a second partial spectrum of incident electromagnetic radiation. A reflected proportion corresponds to a higher harmonic and is in a visible spectral range.

Glazing unit, method for the production thereof and use thereof

A glazing unit is provided for producing an aesthetically pleasing effect, comprising or consisting of at least one pane, said pane having a first structured surface to which a three-dimensional photonic structure is applied and the average refractive index of the photonic structure being higher than approximately 1.6 or higher than approximately 1.8 or higher than approximately 1.95. A method of producing such a glazing unit and the use thereof is also provided.

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.

Sun protection device with angle-selective transmission properties

The present invention relates to a sun collector comprising a flat absorber body () on or in which one or more absorber channels () for the flow of a heat transfer medium are configured. In areas which are not occupied by the one or more absorber channels (), the absorber body () of the present sun collector has penetrable openings () for sunlight to pass through. The sun collector therefore provides the double function of a sun collector with a partially transparent sun protection device.
