Illumination arrangement for a projection system

摘要

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 (L 1 ) generated by and emitted from at least one associated of at least one solid state light source device ( 30 ).
