摘要： An optical projection apparatus includs an illumination system, a projection lens and a reflective light valve between the illumination system and the projection lens. The illumination system includes a first light source assembly, a second light source assembly, a first light integration rod, a second light integration rod and a dichroic mirror. A first light beam and a second light beam with different spectrum are provided by the first light source assembly and the second light source assembly, respectively. Moreover, the projection lens, the reflective light valve and the dichroic mirror are disposed on the transmission path of the first and the second light beam. The dichroic mirror allows the first light beam to pass through, and reflects the second light beam, to make the transmission path of the first and the second light beam identical.

The first integrator has a first light incident end and a first light exit end. The first and the second dichroic elements are respectively disposed at two different parts adjacent to the first light incident end. The first dichroic element, the second dichroic element, and the first light incident end are arranged along a triangular track. The first light source emits a first color light. The second light source emits a second color light. The first color light passes through the first dichroic element and is partially reflected by the second dichroic element to the first light incident end. The second color light passes through the second dichroic element and is partially reflected by the first dichroic element to the first light incident end.
