Vehicle signalling device with a three-dimensional optical effect

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 a transparent zone, said screen being arranged away from said reflector and forming a cavity with said reflector;
• a light source;
• and
• said screen being adapted so that light rays of said light source meet said screen with first ones of these rays being transmitted by said transparent zone without reflection and 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.

• at least one 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 repetitive visual effect of depth;
• wherein the screen is configured so as not to extend to the right of at least some of the light rays that penetrate the cavity.
