Illuminated glazing element with emissivity-reducing coating

Abstract

An illuminated glazing element includes a glass pane having a first surface and a second surface, wherein the glazing element is equipped with at least one light source which is suitable for coupling light into the glass pane in such a way that the light propagates in the glass pane, and is provided with at least one light-scattering structure which is suitable for decoupling the light from the glass pane via the first surface and/or via the second surface, wherein the second surface of the glass pane is provided with an emissivity-reducing coating which includes exactly one electrically conductive layer based on a transparent conductive oxide and the electrically conductive layer has, within the wavelength range from 380 nm to 780 nm, an imaginary component k of the refractive index, for which k<0.035 applies.
