Projection apparatus

A projection apparatus, comprising:

• a light source set, for providing at least a first light beam and a second light beam;
• a light integration rod, having a light incident section and a light exit section opposite to the light incident section, the light incident section being separated into two parts by a first axis, the first and the second light beams being projected into the light integration rod from two different parts of the light incident section and passing through the light exit section to form an illumination beam;
• a light valve, disposed on a transmission path of the illumination beam for reflecting the illumination beam to form an image beam, the light valve having an active surface, a plurality of micro mirrors being disposed on the active surface, each of the micro mirrors being capable of swinging about a swinging axis, the first axis projected to the active surface being coincided with a second axis, and the second axis being parallel to the swinging axis and through a geometric center of the active surface;
• and
• a projection lens, disposed on a transmission path of the image beam.
