Abstract

The invention provides a projection device and a projector, and belongs to the field of projection equipment. The projection device comprises a light source group, a preprocessing assembly, a prism assembly, a main digital micro-reflector, an auxiliary digital micro-reflector and a projection lens; the light source group comprises a main light source and an auxiliary light source, and the wavelengths of light emitted by the main light source and the auxiliary light source are different; the preprocessing assembly is corresponding to the light source group one to one and is used for receiving light emitted by the main light source and the auxiliary light source. The prism assembly is used for receiving light emitted by the preprocessing assembly; the main digital micro-reflector is in one-to-one correspondence with the main light source and is used for receiving and reflecting light reflected by the prism assembly; the auxiliary digital micro-reflector is in one-to-one correspondence with the auxiliary light source and used for receiving and reflecting the light reflected by the prism assembly, and the prism assembly is further used for receiving and transmitting the light reflectedby the main digital micro-reflector and the auxiliary digital micro-reflector. The projection device and the projector can project images and subtitles at the same time, and are compact in structure,small in occupied space and low in 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...
