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.

摘要： An image projecting apparatus includes a light source, a relay lens, a reflective light valve, and a projection lens. The light source is capable of emitting a light beam. The relay lens is disposed to permit the light beam provided by the light source to pass therethrough, and has a lens periphery formed with a notch. The reflective light valve is spaced apart from the relay lens, and is disposed to receive and modulate the light beam passing through the relay lens into an image light beam. The projection lens is disposed proximate to the notch of the relay lens, and is capable of projecting the image light from the reflective light valve to display an image onto a screen. The relay lens has a plurality of light-absorbing regions proximate to the notch for reducing a light-splitting effect attributed to the notch.
