Trim part having a two-dimensional light guide

A trim part comprising:

• a two-dimensional light guide configured to actively lighting a surface portion, wherein the two-dimensional light guide has at least three layers, wherein the at least three layers include two layers and a light guidance layer arranged between the two layers, wherein the two layers and the light guidance layer are films, wherein the two layers have a lower refractive index than the light guidance layer, wherein one of the two layers has decoupling structures for light, wherein the at least three layers form a film composite, wherein the two layers and light guidance layer are coextruded;
• and
• at least one light source arranged on an end face of the two-dimensional light guide, wherein the at least one light source comprises at least one light indirectly connected to the two-dimensional light guide, wherein the at least one light source is arranged, as seen in a viewing direction onto the trim part, hidden behind a non-light-transmissive surface portion and is connected to the two-dimensional light guide, wherein the at least one light source is formed by an input coupling light guide having at least one integrated light.

A method for forming a trim part, the method comprising:

• forming a two-dimensional light guide configured to actively lighting a surface portion, wherein the two-dimensional light guide has at least three layers, wherein the at least three layers include two layers and a light guidance layer arranged between the two layers, wherein the two layers and the light guidance layer are films, wherein the two layers have a lower refractive index than the light guidance layer, wherein one of the two layers has decoupling structures for light, wherein the forming the two-dimensional light guide comprises forming the at least three layers form as a film composite by coextruding the two layers and light guidance layer;
• and
• arranging at least one light source on an end face of the two-dimensional light guide, wherein the at least one light source comprises at least one light indirectly connected to the two-dimensional light guide, wherein the at least one light source is arranged, as seen in a viewing direction onto the trim part, hidden behind a non-light-transmissive surface portion and is connected to the two-dimensional light guide, wherein the at least one light source is formed by an input coupling light guide having at least one integrated light.
