Light-emitting unit for a light-emitting module for a vehicle

An automotive vehicle luminous module comprising at least a first luminous unit and a second luminous unit, the first luminous unit includes a first luminous subassembly includes at least a first light source configured to emit a plurality of first light rays and a first collector configured to collect and reflect the first light rays emitted by the first light source, a second luminous subassembly includes at least a second light source configured to emit a plurality of second light rays and a second collector configured to collect and reflect the second light rays emitted by the second light source, an optical projection system configured to project the first light rays reflected by the first collector and the second light rays reflected by the second collector, the optical projection system includes an optical axis parallel to a longitudinal direction, wherein the first collector and the second collector are offset with respect to one another along the longitudinal direction such that the first collector is arranged between the second collector and the optical projection system, and are offset with respect to one another along a transverse direction perpendicular to the longitudinal direction, and the optical projection system has an optical line focus parallel or substantially parallel to the transverse direction, the first collector includes a first rear edge disposed in a vicinity of the optical line focus of the optical projection system, the second collector includes an object focus at which the second light source is positioned and an image focus at least partially coincident with the optical line focus of the optical projection system, wherein the second collector includes at least two reflective cavities, each of the reflective cavities being offset with respect to one another along the transverse direction.
