Disclosed is a DLP micro projector, the light source of the device for providing light to the projector being configured as a horizontal device (1) and a vertical device (6). A horizontal collimating lens group (2, 3) and a vertical collimating lens group (4, 5) are respectively provided corresponding to the horizontal device and the vertical device. Two spectroscope glasses (7, 8) for reflecting light of different colours are provided sequentially along the optical path of the vertical collimating lens group. The three coloured light rays emitted by the light source can be mutually parallel and incident on the optical components behind. The DLP micro projector can not only reduce the size of projector, but can also solve the possible problem of low light transmission efficiency due to a reduction in the size of projector.
