  • Patent number: 10859755
    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 (A1, A2) 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.

  • Patent number: 10746372
    Abstract: The invention relates to a lighting device with a multiple light function, which comprises a primary light source and secondary light source (2a, 2b) associated with optical elements which are adapted to guide light to the output of the device. The primary light source (2a) is associated with collimating elements (4) and the secondary light source (2b) is associated with light guiding elements (3), whereby the collimating elements (4) and the light guiding elements (3) are arranged in a common light guiding body (A), the output of the light beams is situated behind the level (6) of the exit ends of the collimating elements (4) and on the output side of light guiding body (A) a light scattering filter (7) is arranged.
