19 Claims

1. A glazing comprising:

at least one first pane having a first primary surface and a second primary surface,

at least one light source adapted to emit light,

at least one light coupling system,

wherein the at least one light source is connected to the first primary surface of the first pane via the at least one light coupling system such that light from the at least one light source is to be coupled into the first pane,

at least one light outcoupling system for outcoupling light from the first pane via at least one of the first and second primary surfaces, and

at least one light amplification system arranged locally on a portion of the second primary surface of the first pane and opposite the light coupling system such that the at least one light amplification system is arranged at least in a region of orthogonal projection of the at least one light coupling system onto the first pane, the at least one light amplification system being adapted to deflect at least a portion of the light emitted by the at least one light source and incident on the at least one light amplification system back to the at least one light coupling system.
