Abstract: A projection system for illuminating a projection surface may include at least one light source formed from a plurality of light-emitting elements and an optical integrator having an entrance opening and an exit opening, into the entrance opening of which the light of each light-emitting element is coupled such that the mixed light of all the light-emitting elements emerges from its exit opening, and an imaging optical unit, which projects the light emerging from the exit opening of each integrator onto the projection surface, wherein an optical element is in each case arranged between the exit opening of each integrator and the imaging optical unit, said optical element shifting the virtual image of the entrance opening along an optical axis of the projection system such that its image generated by the imaging optical unit is not visible on the projection surface.
