Abstract:
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 a level of said screen without meeting the semi-reflecting zone.
