Abstract

The invention provides a projection device and a projector, belonging to the field of projection equipment, comprising a light source group, a preprocessing component, a prism component, a main digital micro-reflector, an auxiliary digital micro-reflector and a projection lens. The light source group includes a main light source and an auxiliary light source , the wavelengths of light emitted by the main light source and the auxiliary light source are different; the preprocessing component corresponds to the light source group one-to-one, and is used to receive the light emitted by the main light source and the auxiliary light source; the prism component is used to receive the light emitted by the preprocessing component; the main digital micro-reflection The mirror corresponds to the main light source one-to-one, and is used to receive and reflect the light reflected by the prism assembly; the auxiliary digital micro-mirror corresponds to the auxiliary light source one-to-one, and is used to receive and reflect the light reflected by the prism assembly, and the prism assembly is also used to receive and transmit Light reflected by the primary digital micromirror and the secondary digital micromirror. The projection device and the projector provided by the present invention can project images and subtitles at the same time, have a compact structure, occupy a small space, and have a low use cost.

Description

technical field [0001] The invention belongs to the technical field of projection equipment, and more specifically relates to a projection device and a projector including the projection device. Background technique [0002] The projector is a mechanical device that restores the image and sound recorded on the film, with the screen and amplifier, and is mainly used in theaters. Existing cinema projectors require two projection devices to work together when projecting films, one of which is used to project images and the other is used to project subtitles, which not only takes up a lot of space, but also requires cumbersome debugging work for operators before the projection, and the use cost Also relatively high. Contents of the invention [0003] The object of the present invention is to provide a projection device to solve the technical problems in the prior art that images and letters are projected through different projection devices, occupying a large space and having...
