Abstract
The utility model provides a projection system. The projection system comprises a plurality of light sources with the same light emitting direction; the lighting assembly is located on the light emitting side of the light source; the multiple display chips correspond to the multiple light sources one to one and are located on the side, away from the light sources, of the illumination assembly; the plurality of projection lenses are in one-to-one correspondence with the plurality of display chips and are located at one side, far away from the illumination assembly, of the display chips, the optical axes of the projection lenses are vertical to the side length of one side of the corresponding display chip, the display chips are rectangular, and the optical axes of the projection lenses are vertical to the long side of the corresponding display chip. According to the utility model, the problem that the projection system in the prior art is difficult to give consideration to multi-projection and miniaturization at the same time is solved.
