Abstract
An illumination unit includes a transparent substrate, a light source, a first half mirror, and a mirror. The light source is mounted on the transparent substrate. The first half mirror is disposed on a front side of the transparent substrate. The mirror is disposed on a rear side of the transparent substrate. Light emitted from the light source is repeatedly reflected between the first half mirror and the mirror while being transmitted through the transparent substrate, so as to be output forward from the first half mirror.
