Abstract
A glazing assembly 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-in light, a light source for generating light that can be coupled into the first pane, a second pane having a first main surface and a second main surface, an intermediate layer arranged between the first pane and the second pane, and a light coupling unit which is arranged in the intermediate layer, wherein the light coupling unit is formed from a multilayer film, wherein the multilayer film includes at least one carrier layer and a microprism film.
Claims13
A glazing assembly 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-in light,
- a light source for generating light that is coupled into the first pane,
- a second pane having a first main surface and a second main surface,
- an intermediate layer arranged between the first pane and the second pane,
- a light coupling means which is arranged in a cutout of at least one thermoplastic layer of the intermediate layer,
- wherein the light coupling means is formed from a multilayer film, wherein the multilayer film comprises at least one carrier layer and a microprism film.
A method for producing a glazing assembly that 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-in light, a light source for generating light that is coupled into the first pane, a second pane having a first main surface and a second main surface, an intermediate layer arranged between the first pane and the second pane, a light coupling means which is arranged in the intermediate layer, wherein the light coupling means is formed from a multilayer film, wherein the multilayer film comprises at least one carrier layer and a microprism film, the method, comprising:
- laminating the multilayer film comprising the at least one carrier layer and the microprism film and thereby providing the light coupling means,
- providing the intermediate layer,
- making a cutout in at least one thermoplastic layer of the intermediate layer,
- cutting the multilayer film of the light coupling means to size,
- inserting the cut piece of the light coupling means into the cutout of said at least one thermoplastic layer of the intermediate layer,
- inserting the composite thus formed from intermediate layer and light coupling means between the first pane and the second pane and connecting the elements by lamination,
- arranging at least one light source on the first or second pane.
