Abstract: A projection apparatus includes an illumination system, a light valve, a light beam adjusting element, and a light reflective unit. The illumination system is capable of providing an illumination beam. The light valve, the light beam adjusting element, and the light reflective unit are disposed on a transmission path of the illumination beam. The light valve is disposed between the illumination system and the light reflective unit.

Abstract: A projection apparatus includes a light source, a light valve, a light uniforming device, and a lens module. The light source provides an illumination beam. The light valve on a transmission path of the illumination beam converts the illumination beam into an image beam. The light valve has an active surface with a rectangular shape. The light uniforming device is between the light source and the light value. The lens module is between the light uniforming device and the light value. A refractive power of the lens module along a first direction is different from a refractive power of the lens module along a second direction. An f-number of the illumination beam along a direction parallel to a long side of the active surface of the light valve is greater than an f-number thereof along a direction parallel to a short side of the active surface of the light valve.

Abstract: A projection apparatus includes an illumination system, a light valve, a projection lens, and a first reflective unit. The illumination system provides an illumination light beam. The light valve is disposed on a transmission path of the illumination light beam and capable of converting the illumination light beam into an image light beam. The illumination light beam is transmitted to the light valve vertically. The projection lens is disposed on a transmission path of the image light beam. The first reflective unit disposed on the transmission path of the image light beam is located between the light valve and the projection lens. The first reflective unit is capable of reflecting the image light beam from the light valve to the projection lens. The image light beam reflected by the first reflective unit to the projection lens is perpendicular to the illumination light beam transmitted to the light valve.
