Abstract:
1. Image generation unit, comprising: a first, a second, and a third light source unit configured to generate and emit respective first, second, and third primary illumination light components of primary illumination light as light for a first, a second, and a third partial image to be generated for an image to be displayed; and an image generation and a light redirecting arrangement configured to receive said first, second and third primary illumination light components or a derivative thereof in order to generate said first, second, and third partial images for said image to be displayed and to generate first, second, and third projection light components as light of said first, second and third partial images, respectively, and to emit said first, second, and third projection light components as light of said first, second and third partial images, respectively into or along a common output direction and at least a first and a second light collecting and integration unit, wherein said first and second light collecting and integration unit are arranged directly after said first and said second light source unit, respectively, wherein said first and said second light collecting and integration unit have a monotonically increasing cross-section along a respective optical axis when taken from their respective light incidence face to their respective light exit faces and wherein said first and said second light collecting and integration units have beam shaping properties with respect to said first and second primary illumination light components of said primary illumination light, said beam shaping properties being realized via geometrical properties of the respective light exit faces of said first and said second light collecting and integrating units, respectively.
