Illuminating assembly used in projection systems, comprises optical elements between the illumination optics and an image surface that laterally offset the illumination beam path with the same and/or different beam path direction

摘要

Illuminating assembly comprises illumination optics (1) emitting light onto an image surface (2), e.g. a tilting mirror matrix or a reflecting LCD, on which an image is displayed that is detected by a projection lens (3). Optical elements (5, 6) arranged between the illumination optics and the image surface laterally offset the illumination beam path (4) with the same and/or different beam path direction. Preferred Features: The optical elements are at least two mirror elements with spherical and/or aspherical reflecting surfaces or at least two prism elements with spherical and/or aspherical refracting surfaces.
