Abstract
A vehicle pane with a light guide layer on the pane inner face and a lighting device which introduces light of a light source into the light guide layer by means of a light-coupling device. The light-coupling device has at least one light-coupling element that has a base surface and is optically connected to a light guide layer inner face, which faces the vehicle interior, via the base surface. The light-coupling element may have a light-coupling region which lies opposite the base surface and on which the light source has at least one LED is positioned, said light source emitting light into the light-coupling element via the light-coupling region.
Claims17
A vehicle pane having
- a light guide layer on the pane inner side and having a lighting device, which introduces light from a light source into the light guide layer by a light incoupling device,
- the light incoupling device having at least one light incoupling element which has a base surface and is optically connected, via its base surface, to an inner surface of the light guide layer facing a vehicle interior,
- wherein the light incoupling element has a light incoupling region which is situated opposite the base surface and on which is positioned the light source having at least one LED which radiates light into the light incoupling element via the light incoupling region;
- and
- wherein the light incoupling element has on its light incoupling region a plane light incoupling surface which is arranged parallel to the base surface.
A vehicle pane having
- a light guide layer on the pane inner side and having a lighting device, which introduces light from a light source into the light guide layer by a light incoupling device,
- the light incoupling device having at least one light incoupling element which has a base surface and is optically connected, via its base surface, to an inner surface of the light guide layer facing a vehicle interior,
- wherein the light incoupling element has a light incoupling region which is situated opposite the base surface and on which is positioned the light source having at least one LED which radiates light into the light incoupling element via the light incoupling region,
- wherein the LED is mounted on a carrier plate which is arranged on the underside of the light incoupling element situated opposite the base surface,
- wherein the light incoupling element has a mount keeping the carrier plate fixed relative to the light incoupling element, and
- wherein the mount has at least two pins which are arranged at the light incoupling element inward from the LEDs and in each case offset with respect to the LEDs and which engage by way of a respective securing clip in assigned openings in the carrier plate.
