PURPOSE: A micro projection device is provided to reduce an arrangement space of an optical system by using a lighting plate instead of a lighting lens. CONSTITUTION: A micro projection device(100) comprises an LED light source(110), a lighting plate(120), a beam splitter(130), a reflective micro display(140), and projection lenses(150a,150b,150c,150d). The LED light source emits light. Multiple minute patterns are formed on the lighting plate. The beam splitter separates the light through the lighting plate. The reflective micro display is separated from the lighting plate and displays the separated light as an image. The projection lenses enlarge a beam corresponding to the image and project the beam on a screen. |
