Abstract
The light-guiding optical unit comprising a light guide made of an optically transparent material having the shape of a plate with top and bottom surfaces, a light unit to emit light rays, and a collimating element comprising the first reflective surface configured to reflect light rays that fall onto it in the direction (A, A) towards the light guide output surface. The top or bottom surface of the light guide has a recess whose surface comprises second and third reflective surfaces, which are configured to reflect light rays falling onto them to respective lateral reflective surfaces that are part of the surface of the light guide. A recess is situated between the first reflective surface and the output surface in such a way that a part of the light rays reflected from the first reflective surface pass through this recess after this reflection before falling onto the output surface.
