The present invention relates to a light module. The light module includes a light guide with a light guide sheet and a light injection assembly, and a light source that is arranged so as to inject light rays into the entry surface of the at least one injection assembly. The guide sheet include a film with a light extraction region with microstructures capable of redirecting the light injected into the guide sheet toward the outside of the light module. The film includes microstructures on a first face and on a second face. For each portion from among portions of the light extraction region that are at different distances from a light injection edge surface, a sum of a density of microstructures on the first face and on the second face is an increasing function of the distance between the portion and the injection edge surface.
A luminous module comprising:
A piece of automotive vehicle equipment comprising a luminous module, wherein the luminous module includes a light guide including a sheet for guiding light, the light guiding sheet being configured to receive light rays via at least one light-injection edge, and to reflect the light rays in a direction substantially normal to the guiding sheet, and at least one injecting assembly configured to receive light rays from an entrance surface and to guide the light rays so as to inject them into the light-injection edge of the light guiding sheet, a light source arranged so as to inject light rays into the entrance surface of the at least one injecting assembly, wherein the guiding sheet includes a film, the film includes at least one light-extraction zone including microstructures capable of redirecting the light injected into the flexible guiding sheet at least in the substantially normal direction, wherein the film includes microstructures on a first side of the film and on a second side of the film, wherein, for each portion among portions of the light-extraction zone having different respective distances from the light-injection edge, a sum of a microstructure density on the first side in the portion and of a microstructure density on the second side in the portion, is an increasing function of the distance between the portion and the light-injection edge of the guiding sheet.
