Abstract
A two-dimensional light guide has at least three layers, including two layers formed as films have a lower refractive index than a light guidance layer arranged between them. One of the films has decoupling structures for the light. The layers form a film composite in which the light guidance layer is formed as a film. A lighting element can include having such a two-dimensional light guide and a coupled input coupling light guide. A trim part can have a light source coupled with the two-dimensional light guide and include lighting and the input coupling light guide is arranged such that a surface portion is actively lit and a non-light-transmissive surface portion hides the light source and the coupling when viewed from a viewing direction.
