LIGHT GUIDE AND LIGHTING SYSTEM WITH LIGHT GUIDE

The present invention relates, first, to a light guide capable of achieving a lighting with high homogeneity of the light emitted by said light guide on a surface of the light guide (in other words, an external user does not perceive any light gradient on the surface to be illuminated) and, second, to a lighting system comprising said light guide, suitable for installing in a vehicle, wherein this system does not use a diffuser which covers the visible surface of the light guide.The main particular feature of this invention resides in the fact that the light guide (10) internally comprises two types of different light extraction structures arranged interspersed between each other along the longitudinal direction "X" of the light guide (10): a plurality of optics (3a', 3b', 3c') with a triangular or pyramidal cross section, in order to extract the light which moves internally through the light guide (10) in a practically longitudinal direction; and a plurality of surface engravings (2), in order to extract the light which moves in a more transverse direction.
