摘要： A projection apparatus including an image source, an imaging module and a beam splitting module is provided. The image source provides an image beam. The imaging module is disposed on a transmission path of the image beam and has an aperture stop. The beam splitting module is disposed on the transmission path of the image beam and located on or near the aperture stop. The beam splitting module includes a plurality of aperture stop sub-regions, and the beam splitting module separates a plurality of image sub-beams of the image beam irradiating these different aperture stop sub-regions. These image sub-beams respectively propagate towards different directions after travelling to these aperture stop sub-regions.

摘要： A projection apparatus includes an optical engine base, a light source, a light valve, a lens module, and a fan. The light source is disposed at the optical engine base for emitting an illumination beam. The light valve is disposed at the optical engine base for converting the illumination beam into an image beam. The lens module is disposed at the optical engine base and includes a lens barrel and a lens assembly disposed in the lens barrel for converting the image beam into a projection beam. The fan is disposed at the optical engine base, and adjacent to the lens module. The fan is used for providing an air flow to cool the lens module.
