ABSTRACT:
An image projector projects images according to inputted image data. A light source unit has at least a plurality of LED light sources configured as a single unit for emitting an illumination. A space modulation element is modulated according to inputted image data. An illumination optical unit leads the illumination light emitted from the light source unit, and illuminates the space modulation element. A projection optical unit projects an image illuminated by the illumination optical unit and modulated by the space modulation element. The light source unit is configured removably from the image projector.
