Patent number: 9121564Abstract: A device and corresponding module are for a signaling light and/or lighting an exterior or interior ambient of a motor-vehicle passenger compartment including a type of light source. The device comprises an optical assembly of a first reflector including a mirror and a second reflector including a semi-transparent mirror. Light emitted by an LED is diffused in a curtain diffuser of a transparent material. Planes or mid-planes of the mirror, the semi-transparent mirror, and the diffuser are mutually parallel. Light transmitted or reflected by the assembly is transmitted and visible to an observer from a surface of the second reflector that is opposite to that facing other elements of the assembly. The diffuser includes a lighting sub-assembly arranged in space between the mirror and semi-transparent mirror and having a transparent optical material and a light source arranged for emission of light rays propagated within a thickness of the optical material.Type: GrantFiled: March 18, 2011Date of Patent: September 1, 2015Assignee: AUTOMOTIVE LIGHTING REAR LAMPS FRANCE S.A.S.Inventor: Alain Buisson

Publication number: 20150009692Abstract: The invention relates to a lighting device, in particular for a motor vehicle, comprising LEDs secured to a printed circuit board (PCB). The device is characterised in that a system is positioned substantially perpendicularly to the LEDs (5) in front of the illuminating face of the LED, said system comprising parallel opaque plates (1, 2), of which at least one of the faces is a light colour, preferably white. According to the invention, at least two of the aforementioned parallel plates rest on the PCB (4) and/or on the periphery thereof, on each side of at least one LED borne by said PCB, such as to define a channel having a base in which the LEDs are distributed; the wall-forming plates are deployed substantially perpendicularly to the mid-plane of the PCB such as to channel the light emitted by the LEDs, which leaves the device on the side of the plates opposite the above-mentioned side resting on or around the PCB; and the at least one light-coloured or white face of the plates faces into the channel.Type: ApplicationFiled: January 30, 2013Publication date: January 8, 2015Inventor: Alain Buisson
