Abstract:
A light guide comprising an external surface forming a guiding diopter, the guide being suitable for guiding light rays by reflection on the guiding diopter. The guide comprises at least one decoupling portion, with a refraction decoupling diopter arranged so as to refract light rays to decouple them from the guide, and thus transmit them out of the guide through the refraction decoupling diopter.
