Abstract
An illumination optic system includes a convex mirror to reflect light from a light source to towards a lens. The light source is at a first focus position and the lens is at a second focus position of the mirror. The system also includes a reflector to reflect light not incident on the lens toward the convex mirror. The reflector has a light guide hole to guide light to the incidence surface of the lens.
