ABSTRACT:
A light integrating device for an illumination system and an illumination system. The illumination system includes a first light source module and a second light source module providing a first light and a second light, respectively. The device includes first and second light collecting elements and a beam splitting element. The first light travels into the first light collecting element and is split into a plurality of light groups by the beam splitting element. At least one light group travels into the second light collecting element from the beam splitting element. The second light travels into the second light collecting element, is reflected by the beam splitting element and emits out from the second light collecting element along the principle axis of the light integrating device together with the at least one light group which is split from the first light and travels into the second light collecting element.
