摘要： A high efficiency micro projection optical engine includes a light source module, a lens assembly, a micro display panel and a projection lens. Wherein the light source module includes light emitting elements and shaping lens module used to collect and shape the received light beams. The lens assembly is arranged on the path of the emission light of the shaping lens assembly. The shaping lens module and lens assembly form an image of the luminous surface of the light emitting elements in the vicinity of the micro display panel. The micro display panel which is arranged on the path of emission light of the lens assembly modulate incident light and image light with image information is obtained. The projection lens is used to project the image information on the micro display panel and form an image onto a screen. The optical engine of present invention enhances efficiency by means of critical illumination, furthermore, the whole optical engine only relates to illumination device, micro display panel and projection lens, so the optical system has the features that the design of light path is simple and advantage of compact structure and small size.
