ABSTRACT:
An auto license plate's illumination structure comprising a main cover transparent and engaged to license plate, a light source cover opaque and engaged to main cover's upper part and a few lighting installations to be hidden inside the light source cover. The main cover's inner wall is provided with a pattern of some decorative figures formed by many recessions in cross direction and parallelism. Of recession, the side wall which relatively close to light source is angled 45 degrees, and its remaining one at 90 or any other appropriate degrees. As passing main cover's inner wall, the lights of transmission from hidden light sources on one side will thus make an internal total reflection and shoot out from its outer wall, thereby illuminating license plate and, in particular, its decorative figures with the most brightness.
