摘要： A projection apparatus including a light source set for providing a first light beam and a second light beam, a light integration rod having a light incident section and a light exit section, a light valve and a projection lens is provided. The light incident section is separated into two parts by a first axis. The first and second light beams are projected into the light integration rod in two different parts of the light incident section, and then through the light exit section to form an illumination beam. Micro mirrors are disposed on an active surface of the light valve. Each of the micro mirrors is capable of swinging about a swinging axis. The first axis projected to the active surface is coincided with a second axis which is parallel to the swinging axes and through a geometric center of the active surface.
