摘要： A projector includes at least one light source, a light combination assembly, a light-shape adjusting element, an illuminating assembly, and an imaging assembly. The light source is used for emitting at least one light beam. The light combination assembly is disposed at the transmission path of the light beam for transferring the light beam to an illumination beam. The light-shape adjusting element is disposed in the light combination assembly and located at the transmission path of the light beam for adjusting a light shape of the light beam, in which the light shape of the light beam is adjusted to be an elliptical shape. The imaging assembly is disposed at the transmission path of the illumination beam for transferring the illumination beam to an image beam. The imaging assembly is disposed at the transmission path of the image beam for projecting the image beam.

摘要： A feature surface projection system includes a projector, a camera, and a controller. The projector projects a structured light and an image beam to a feature surface at different times. The structured light forms a structured light pattern on the feature surface, and the image beam forms an image on the feature surface. The camera photographs the structured light pattern and the image at different times. The controller is electrically connected to the projector and the camera, calculates a position of a feature point of the feature surface, and determines a difference between a position of a feature point of the image and the position of the feature point of the feature surface to determine whether to adjust the image beam. A projection method for a feature surface is also provided. The feature surface projection system provides an automatic alignment function between a projected content and the feature surface.

摘要： 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.

摘要： A projection device including a light combining system, an illumination system, and a projection lens is provided. The light combining system is configured to provide a combined beam. The illumination system is disposed on a transmission path of the combined beam and configured to receive the combined beam to generate an illumination beam. At least one light valve is disposed on a transmission path of the illumination beam and converts the illumination beam into an image beam. The projection lens is disposed on a transmission path of the image beam and configured to project the image beam out of the projection device. The light combining system is located in a first layer space. The at least one light valve is located in a second layer space. The first layer space is different from the second layer space. The first layer and second layer spaces overlap in the gravitational direction.

摘要： An illumination system configured to provide an illumination light is provided. The illumination system includes a light source, a light-homogenizing device, and a light-homogenizing element. The light source includes multiple light-emitting units, and the light-emitting units emit multiple light beams respectively. The light-homogenizing device includes a micro-lens-array element. The micro-lens-array element includes multiple micro lenses, and each of the light beams irradiates at least two of the micro lenses. The light beams are totally overlapped, non-overlapped, or partially overlapped with each other before being incident on the light-homogenizing device, and overlapped with each other on an incident surface of the light-homogenizing element. A projection device is also provided.

摘要： An illumination system including two light source modules, two light guiding modules, a first reflector, and a light homogenization element is provided. The two light guiding modules are respectively disposed on transmission paths of light beams generated by the two light source modules to generate two guiding light beams. One of the guiding light beams is reflected to the light homogenization element by the first reflector. The other of the guiding light beams is directly transmitted to the light homogenization element. The guiding light beams are emitted from the light homogenization element and form an illumination light beam. A projection apparatus is also provided.
