Luminous device imaging the lit surfaces of at least two collectors

A luminous device of a motor vehicle, comprising:

• a lens;
• a first light source and a second light source that are each able to emit light rays;
• a first collector and a second collector each with a reflective surface configured to collect and reflect the light rays emitted by the first light source (4;
• 104;
• 204;
• 304) and the second light source, respectively;
• an optical system configured to project the light rays reflected by the reflective surfaces of the first collector and of the second collector, respectively, into a first light beam and a second light beam along an optical axis of the luminous device;
• characterized in that the first light beam is a lighting beam with or without an upper flat cut-off and the second beam is a signaling beam,
• the optical system has a first focal point located axially behind a front limit of the reflective surface of the first collector,
• the optical system has a second focal point located axially behind a front limit of the reflective surface of the second collector,
• the optical system further comprises a grained dioptric interface configured to scatter the second light beam, where the grained dioptric interface is formed on a second entrance face that is distinguished from a first entrance face, the lens is a main lens,
• the optical system further comprising an intermediate lens with the grained dioptric interface, said intermediate lens being placed optically between the reflective surface of the second collector and the main lens,
• the optical system is configured to form a luminous image of the reflective surface of each of the first collector and second collector, and
• each of the first light beam and the second light beam forms a portion or the entirety of a lighting or signaling function that is distinct from the lighting or signaling function of the other of said first and second beams.
