Illumination device for vehicles with a housing closed off by a transparent covering plate in which a hologram module is arranged containing a light source unit with a first and a second light source (3, 3', 3") and an optical unit with a hologram element for generating a illuminated holographic figure, - where the optical unit features a first reflector (7, 7', 7") allocated to the first light source (3, 3', 3") and a second reflector (7, 7', 7") allocated to the second light source (3, 3', 3") by means of which light (10, 10', 10") emitted from the respective allocated light source (3, 3', 3") can be deflected in the direction of the hologram element, and - where a screening element (13, 13') protrudes in a transitional area between the first and the second reflector (7, 7', 7") in such a way that scattered light (15, 15', 15") emitted by the first light source (3, 3', 3") that does not hit the allocated first reflector (7, 7', 7") is prevented from hitting the adjacent second reflector and that, the other way round, scattered light (15, 15', 15") emitted by the second light source (3, 3', 3") that does not hit the second reflector (7, 7', 7") is prevented from hitting the first reflector (7, 7', 7"), characterised in that the optical unit features at least one aperture element (9, 9', 9") for limiting a emission angle range (φ) of the light sources (3, 3', 3"), and in that the aperture elements (9, 9') are arranged in such a way that light (10, 10', 10") emitted from the light sources (3, 3', 3") is shone out of the recess formed by the at least one aperture element (9, 9') into the hologram module, where the emitted light (10, 10', 10") enters a chamber of the hologram module at an acute emission angle range (φ) and hits the respective allocated reflector (7, 7', 7") as useful light (10, 10', 10"). - where the optical unit features a first reflector (7, 7', 7") allocated to the first light source (3, 3', 3") and a second reflector (7, 7', 7") allocated to the second light source (3, 3', 3") by means of which light (10, 10', 10") emitted from the respective allocated light source (3, 3', 3") can be deflected in the direction of the hologram element, and - where a screening element (13, 13') protrudes in a transitional area between the first and the second reflector (7, 7', 7") in such a way that scattered light (15, 15', 15") emitted by the first light source (3, 3', 3") that does not hit the allocated first reflector (7, 7', 7") is prevented from hitting the adjacent second reflector and that, the other way round, scattered light (15, 15', 15") emitted by the second light source (3, 3', 3") that does not hit the second reflector (7, 7', 7") is prevented from hitting the first reflector (7, 7', 7"), characterised in that the optical unit features at least one aperture element (9, 9', 9") for limiting a emission angle range (φ) of the light sources (3, 3', 3"), and in that the aperture elements (9, 9') are arranged in such a way that light (10, 10', 10") emitted from the light sources (3, 3', 3") is shone out of the recess formed by the at least one aperture element (9, 9') into the hologram module, where the emitted light (10, 10', 10") enters a chamber of the hologram module at an acute emission angle range (φ) and hits the respective allocated reflector (7, 7', 7") as useful light (10, 10', 10"). a screening element (13, 13') protrudes in a transitional area between the first and the second reflector (7, 7', 7") in such a way that scattered light (15, 15', 15") emitted by the first light source (3, 3', 3") that does not hit the allocated first reflector (7, 7', 7") is prevented from hitting the adjacent second reflector and that, the other way round, scattered light (15, 15', 15") emitted by the second light source (3, 3', 3") that does not hit the second reflector (7, 7', 7") is prevented from hitting the first reflector (7, 7', 7"), characterised in that the optical unit features at least one aperture element (9, 9', 9") for limiting a emission angle range (φ) of the light sources (3, 3', 3"), and in that the aperture elements (9, 9') are arranged in such a way that light (10, 10', 10") emitted from the light sources (3, 3', 3") is shone out of the recess formed by the at least one aperture element (9, 9') into the hologram module, where the emitted light (10, 10', 10") enters a chamber of the hologram module at an acute emission angle range (φ) and hits the respective allocated reflector (7, 7', 7") as useful light (10, 10', 10").
