VEHICLE SIGNALLING DEVICE WITH A THREE-DIMENSIONAL OPTICAL EFFECT
First Claim
1. A luminous signalling device, particularly for motor vehicles, suitable to light a space with a main lighting axis, comprising the following:
- a reflector with a reflecting surface directed so as to face said space to be lit;
a screen arranged opposite said reflector, between said reflector and said space to be lit, the screen comprising a semi-reflecting zone;
said screen is arranged away from said reflector and forming a cavity with said reflector;
at least one of the surfaces formed by said screen or said reflector is convex;
a support of light source configured so that light rays of said light source penetrate said cavity according to a main direction directed towards said space to be lit, and some of said light rays meet said semi-reflecting zone;
some of these rays are transmitted by said semi-reflecting zone and others of these rays are reflected by said semi-reflecting zone, then by said reflector into said cavity, in such a way as to generate a repetitive visual effect of depth;
wherein said rays are a first part of the light rays emitted by said light source;
said screen is configured and arranged in relation to the direction of emission of the light source, so that a second part of the light rays emitted by the light source leaves the cavity at the level of said screen without meeting the semi-reflecting zone.

Abstract
A light signalling device, particularly designed for motor vehicles. The device has a reflector with a reflecting surface and a screen arranged opposite the reflector and having a semi-reflecting zone. The screen being arranged away from the reflector and forming a cavity with the reflector. The light rays of the source penetrate the cavity; and some of these rays are transmitted by the semi-reflecting zone, and others of these rays are reflected by the semi-reflecting zone, then by the reflector into the cavity in such a way as to generate a repetitive visual or three-dimensional effect of depth. The screen is configured and arranged in relation to the direction of emission of the light source in such a way that another part of the light rays leaves the cavity at the level of the screen without meeting the semi-reflecting zone.

19. A luminous device, particularly for motor vehicles, suitable to light a space with a main lighting axis, comprising the following:
-
a reflector with a reflecting surface directed so as to face said space; a screen arranged opposite said reflector, between said reflector and said space, said screen comprising a semi-reflecting zone and being arranged away from said reflector and forming a cavity with said reflector; a light source; and at least one of said screen or said reflector being adapted so that light rays of said light source meet said semi-reflecting zone with first ones of these rays being transmitted by said semi-reflecting zone in a predetermined pattern of light and second ones of these rays being reflected by said semi-reflecting zone towards said reflector and then back to said semi-reflecting zone in such a way as to generate at least one subsequent pattern of light that is subsequently the same as said predetermined pattern of light but smaller in order to give a repetitive visual effect of depth. - View Dependent Claims (20, 21, 22, 23, 24, 25, 26, 27)
