ABSTRACT:
The illumination device comprises at least one light source, and a light pipe positioned at the front side of a license plate, and a light diffusing means. A light of the light sources is led, the light pipe emitting a leading light from the surface of the license plate face. The light emitted from the observed face is diffused by the light diffusing means. The light diffusing means is provided with, rugged portions of an observed face opposite to a light emitting face, or, a light diffusing layer composed of two or more kinds of light transmitting materials, refractive indexes of which are different each other, on the observing face, and a light led from a light leading face is reflected and diffused on the light diffusing layer.
