A vehicle window for separating a vehicle interior from outer surroundings, comprising a glass pane with a light guide body made of glass on a region of the interior-side surface of the glass pane,
- wherein a surface of the light guide body facing the glass pane and a surface of the light guide body facing away from the glass pane enclose a wedge angle such that a thickness of the light guide body decreases in a direction from a lower edge to an upper edge of the glass pane,
- wherein the light guide body is secured to the interior-side surface of the glass pane by means of laser welding,
- wherein the surface of the light guide body facing the glass pane is positioned with its full surface against the region of the interior-side surface of the glass pane and is joined to the interior-side surface by means of a circumferential peripheral weld, and wherein along the weld, an adhesion promoter that contains glass frits is arranged between the glass pane and the light guide body.
A method for producing a vehicle window, comprising:
- (a) arranging a light guide body made of glass on a region of an interior-side surface of a glass pane wherein a surface of the light guide body facing the glass pane and a surface of the light guide body facing away from the glass pane enclose a wedge angle and a thickness of the light guide body decreases in a direction from a lower edge to an upper edge of the glass pane, and
- (b) securing the light guide body on the glass pane by means of laser welding,
- wherein glass frits are arranged between the light guide body and the glass pane.
