Illumination arrangement for color picture projection

Abstract

This invention involves a lighting arrangement for color image projection with at least two lighting units, whose light will hit image-forming elements, such as DMDs or grating light valves via optical elements, so that a subsequent optical projection system will project a multi-colored image on a projection surface. This invention shows that the illuminating optical paths will hit one or more image-forming elements from different directions and that once they pass the image-forming element or elements, they will be combined into one common optical projection path.
