ILLUMINABLE GLAZING
A glazing arrangement includes a first pane having a first main surface and a second main surface, wherein the first pane is provided to at least partially transmit coupled light, a light source for producing light that can be coupled into the first pane, a light extraction system to couple light out of the first pane via one of the two main surfaces, wherein the light extraction system includes a transparent coating with a refractive index that differs from, in particular is higher than, that of the air and that of the first pane, which transparent coating is arranged in a planar manner at least sectionally on one of the two main surfaces.
1 . A glazing arrangement comprising:
a first pane having a first main surface and a second main surface, wherein the first pane is provided to at least partially transmit coupled light,
a light source for producing light that can be coupled into the first pane,
a light extraction system adapted to couple light out of the first pane via one of the first and second main surfaces,
wherein the light extraction system comprises a transparent coating with a refractive index that differs from that of the air and that of the first pane, which transparent coating is arranged in a planar manner at least sectionally on one of the first and second main surfaces.
2 . The glazing arrangement according to claim 1 , wherein the transparent coating is roughened.
3 . The glazing arrangement according to claim 1 , wherein the transparent coating comprises multiple body elements.
4 . The glazing arrangement according to claim 3 , wherein the body elements are elliptical, cylindrical, or spheres.
5 . The glazing arrangement according to claim 3 , wherein the body elements are partially filled or hollow.
6 . The glazing arrangement according to claim 3 , wherein the body elements are coated with a coating of titanium oxide or a fluorescent substance.
