  • Patent number: 11982417
    Abstract: A lighting and/or signaling device, comprising a light guide, at least one LED light source, wherein an inlet and diffusion wall and the light outlet wall are opposite to each other along a main optical axis (X). The lighting portion comprises a middle lighting portion aligned with the LED light source and the light emission portion, and a peripheral lighting portion. The device comprises at least one reflector element associated with the light inlet and diffusion wall of the light guide and directly facing the respective extraction elements so as to reflect light towards the light outlet wall. A diffusion layer is arranged to cover the lighting portion on the side of the light outlet wall. Cylindrical optics are provided on the light outlet wall, at the middle lighting portion, which extract the incident light beams thereon, towards the diffusion layer.

  • Publication number: 20230211723
    Abstract: An automotive light comprising a lighting assembly which is located inside the rear body, is adapted to backlight a corresponding transparent or semi-transparent sector of the front half-shell, and comprises: a pair of light-guide bars made of photoconductive material, which extend toward each other inside the rear body, while remaining both substantially grazing the front half-shell, and have their respective proximal ends adjacent and aligned to one another; and a pair of electrically-powered light sources that are located within the rear body each adjacent to the distal end of a respective light-guide bar, and are oriented so as to direct the light produced inside the body of the facing light-guide bar; the proximal ends of both light-guide bars being shaped so as to form respective plate-like heads that are locally substantially coplanar to each other and are arranged inside the rear body one spaced beside the other, so as to form/delimit therebetween a small transversal slot, which is substantially strai

  • Patent number: 11499690
    Abstract: A lighting and/or signaling device comprising a container body which delimits a containment seat that houses a first luminous source adapted to emit a first luminous beam, and a second luminous source adapted to emit a second luminous beam. The containment seat adapted to be at least partially crossed by the luminous beams produced by said luminous sources, so as to transmit the luminous beams outside the containment seat. The containment seat is divided into a first compartment which houses the first luminous source and into a second compartment which houses the second luminous source. The lenticular body comprises a first transmission portion, facing the first compartment that transmits, at least partially, towards the outside the first luminous beam, a second transmission portion facing the second compartment that transmits, at least partially, towards the outside the second luminous beam.

  • Patent number: 11346994
    Abstract: A lighting and/or signaling device, comprising: a light guide adapted to receive a light ray beam to a light outlet wall which creates a lighting portion of the lighting and/or signaling device, at least one LED light source adapted to receive the light beam, transmitted by total internal reflection towards the light outlet wall. The device includes at least one reflector element associated with the light inlet and diffusion wall of the light guide and directly facing the respective extraction elements so as to reflect light towards the light outlet wall. A diffusion layer is arranged to cover the lighting portion on the side of the light outlet wall. The diffusion layer has a differentiated transmission factor according to the light intensity of the incident light rays on the lighting portion so as to obtain a uniform light intensity over the whole lighting portion.
