Image projection apparatus

Abstract

An image projection apparatus includes a light source for emitting a plurality of monochromatic laser beams of different wavelengths; a first light transmit unit comprising a plurality of optical fibers for passing the respective monochromatic laser beams therethrough; a light switch unit having a plurality of reflection mirrors for selectively deflecting the respective monochromatic laser beams at a predetermined angle; a plurality of quadrangular bean generating units for converting the deflected monochromatic laser beams into quadrangular beams, each of which having a predetermined ratio of width to height; a plurality of panels for receiving the quadrangular beam-converted monochromatic laser beams and forming monochromatic images corresponding to the monochromatic color laser beams; and a plurality of projection lenses disposed opposite to the plurality of panels. Accordingly, by using the light switches and 3 single-plate panels, a plurality of different images are simultaneously realized and the utilization efficiency of the light can be improved.
