  • Patent number: 10788609
    Abstract: A lighting and/or signaling device comprising a light guide which extends from a light input and diffusion wall to a light output wall that realizes a lighting portion, at least one LED light source, suitable to emit a light beam and facing a light input portion of said light input and diffusion wall. The lighting portion includes a central lighting portion and a peripheral lighting portion, surrounding the central lighting portion, the light guide being provided with extraction elements arranged on the light input and diffusion wall. A hologram is arranged between the LED light source and the light input portion so as to distribute according to a predefined pattern the light rays emitted by the LED light source and obtain a predefined luminance on the central lighting portion and the peripheral lighting portion.

  • Patent number: 10781990
    Abstract: A vehicle light having a container body having a first perimetral profile, a lenticular body, having a second perimetral profile, wherein the first and second perimetral profile of the container body and the lenticular body are at least partially counter-shaped to each other in order to interface at a welding interface of an abutment edge of the lenticular body. The container body delimits a containment seat that houses a light source and the lenticular body is applied to the container body so as to close the containment seat. A redirection surface is adapted to receive laser beams, to concentrate and reflect them towards the welding interface. The redirection surface is arranged on an inner face of the abutment edge, the inner face facing the containment seat and incident with the welding interface. A method of making the vehicle light is also disclosed.

  • Patent number: 10746367
    Abstract: Vehicle light comprising a container body, a lenticular body, a light guide, including a body having a prevailing longitudinal extension (L) that defines the propagation direction of the light beam inside the body by total internal reflection. The body has a first breakline that extends from the first to the second side wall. The first breakline includes a plurality of first holes that produce, through successive refractions, a scattering the light rays (Ri) towards the light outlet wall so as to emit a light beam with opalescent effect. The first holes are adjacent to each other without interruption, and the first holes of the first breakline are pass-through with respect to a thickness of the body of the light guide, penetrating from a first face to a second face of the body for a depth equal to the thickness.

  • Publication number: 20200182428
    Abstract: A lighting device comprising at least two LED light sources, powered and activated separately, each facing a respective light input wall of a corresponding light guide, the light guides transmit and emit the light of the LED light sources through at least two distinct lighting faces at a front wall of the lighting device. The light guides are provided with diffuser extractor elements arranged on a rear wall of the light guide, opposite the front wall, and shaped so as to extract the light outside the lighting device. The light guides are juxtaposed and adjacent to each other at at least one respective inner wall. The light guides are mechanically and optically separated by barrier elements which prevent the passage of light between the light guides at one inner wall. The barrier elements are separator septa opaque to the light extending from the rear wall to the front wall, crossing it completely.

  • Patent number: 10655811
    Abstract: A vehicle light comprising a container body and a lenticular body joined at least partially to close the container body, wherein the container body delimits a containment seat housing at least one light source that faces at least one light guide having a light guide body shaped to receive the light beam from a light input wall, and to transmit it to a light output wall and from this to a main light emission portion of the lenticular body. At least first extractor elements are placed between the light input wall and the light output wall, which extract a first extracted portion of the light beam emitted by the light source and direct it onto first reflecting elements separate from the light guide. The first reflecting elements reflect the first extracted portion towards the lenticular body at a first auxiliary light emission portion, separate from said main emission portion.
