Abstract: An illumination arrangement (1) for a projection system is proposed comprising a light source device (10) and a light collecting, integrating and redirecting device (20). The light source device (10) comprises at least one solid state light source device (30). The light collecting, integrating and redirecting device (20) comprises at least one light integrating device (50), which is adapted to directly receive and to integrate at least a part of primary illumination light (L1) generated by and emitted from at least one associated of at least one solid state light source device (30).

Abstract: An image generation unit (10) is proposed comprising a first, a second, and a third light source unit (S1, S2, S3) which are adapted in order to generate an emit respective first, second, and third primary illumination light components (Lr1, Lg1, Lb1).

Abstract: It is proposed to provide in an illumination unit (10) a light combining section (15) being adapted for receiving and combining first and second primary illumination light (L11, L12) or a derivative thereof and a light collecting, integrating and redirecting section (20) being adapted for receiving, collecting, integrating and redirecting first and second primary illumination light (L11, L12) or a derivative thereof, wherein said light combining section (15) and said light collecting, integrating and redirecting section (20) are at least partly arranged in a spatially mingled manner with respect to each other. Thereby from said first and second primary illumination light (L11, L12) collected, integrated and redirected combined primary illumination light (CL1) can be obtained and emitted as secondary illumination light (L2) having controlled spectral properties and an essentially uniformized spatial intensity distribution.
