LIGHTING OR SIGNALLING DEVICE WITH DEPTH EFFECT
First Claim
1. A lighting or signalling device for a motor vehicle, comprising:
- at least one light source emitting a light beam, comprising a plurality of light signals, in the direction of an output block of the lighting or signalling device, wherein the output block comprises a stack of screens, said stack of screens comprising at least a first screen and a second screen, each of said first and second screens comprising an entry face receiving said plurality of light signals and an exit face, said entry face and said exit face of each screen being joined by a top face and a bottom face defining between them a screen thickness, at least one of said first or second screens comprising at least one optical pattern produced in the thickness of the screen in question, comprising a through cavity produced in the screen that comprises it.

Abstract
A lighting or signalling device in which a particular output unit of the device in question is formed, the output unit consisting of a stack of screens, independent of one another; each screen comprises a plurality of optical patterns produced in its thickness, able to divert light signals emitted by a light source; the spread of the light beam emerging from the device in question is thus adjustable in a first diffusion direction (OX), corresponding, for each screen in question, to a direction parallel to a plane defined by the screen and containing the optical patterns, and in a second diffusion direction (OZ), corresponding to a direction parallel to a plane roughly perpendicular to the planes defined by the screens, the spread on the second diffusion plane depending on the relative positions of the various screens. In this way in particular a “block of illuminated material” effect is obtained.
