Abstract

A light for a motor vehicle includes a flat light guide with decoupling structures for light on the front side, as well as at least one light source for coupling light into the flat light guide. A graphic is arranged on the rear side of the light guide, the graphic being constructed from regions with different degrees of reflectivity and/or colors. The decoupling structures and the graphic have the same graphical pattern and are oriented in relation to one another. The at least one light source couples the light into the flat light guide on the end face.

at least one light source arranged to output light into one of the end faces of the flat light guide; and

a graphic arranged on the rear side of the flat light guide, wherein the graphic is constructed from regions with different degrees of reflectivity or colors, and wherein the decoupling structures and the graphic have the same graphical pattern and are oriented in relation to one another.

2. The light of claim 1 , wherein the decoupling structures are etched, stamped, or engraved flatly into the front side and rear side.

8. The light of claim 1 , wherein the at least one light source is a field or a row of discrete light emitting diodes, which are controllable individually or in groups, and which couple in light along one or more of the end faces of the flat light guide.

9. The light of claim 8 , wherein a first one or two of the end faces are longer than a second one or two of the end faces, and wherein the light is coupled via the first one or two of end faces of the flat light guide.
