Abstract

A projection apparatus including a light source module, an eccentric-collimating lens, a prism lens group, a light valve and a projection lens is provided. The light source module is configured to provide an illumination light beam. The eccentric-collimating lens is disposed between the light sources and the light valve on a transmission path of the illumination light beam. The light valve is configured to convert the illumination light beam into an image light beam. The projection lens is configured to project the image light beam out of the projection apparatus. A first included angle between a first transmission direction of the illumination light beam incident on the eccentric-collimating lens and a central axis of the eccentric-collimating lens is greater than 0. The first transmission direction and a second transmission direction of the image beam exiting from the light valve are perpendicular to each other.
