Publication number: 20200182428Abstract: 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.Type: ApplicationFiled: December 6, 2019Publication date: June 11, 2020Applicant: MARELLI AUTOMOTIVE LIGHTING ITALY S.p.A.Inventors: Michele Antonipieri, Fabio Leone

Patent number: 10591128Abstract: A lighting and/or signalling device, in particular for the automotive sector, comprising: at least two LED light sources, powered and activated separately, each facing a respective light input wall of a corresponding light guide, wherein the light guides emit the light of the LED light sources through at least two separate lighting portions at a front wall. The light guides are equipped with diffuser elements arranged on a rear wall opposite to the front wall. At least one reflector element is associated with each light guide directly facing the respective diffuser elements so as to reflect the light towards the front wall. 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 the at least one inner wall.Type: GrantFiled: July 24, 2018Date of Patent: March 17, 2020Assignee: MARELLI AUTOMOTIVE LIGHTING ITALY S.P.A.Inventors: Jean-Pascal Herlin, Lorenzo Spadaccini, Giulio Manfreda, Michele Antonipieri

Patent number: 9927084Abstract: A vehicle light comprising a container body and a lenticular body. The light comprises a substrate that supports a main light source that is embedded in a cover layer suitable to allow the diffusion inside it of the main light beam. The cover layer is disposed on the side opposite to the lenticular body with respect to the substrate. The substrate comprises at least one transparent portion to the light beam suitable to transmit the main light beam towards the lenticular body and, through this, to the outside of the vehicle light, wherein the substrate comprises at least one opaque portion to the main light beam, adjacent to said transparent portion in order to allow the passage of the main light beam exclusively at said transparent portion. The transparent portion defines a main light pattern of the vehicle light.Type: GrantFiled: June 15, 2016Date of Patent: March 27, 2018Assignee: AUTOMOTIVE LIGHTING ITALIA S.p.A.Inventors: Stefano Marchesin, Franco Marcori, Igor Di Vora, Michele Antonipieri
