The present invention is an illumination case used for decoration or advertisement. It includes a case-body, a front cover, an inner frame, a light source, a transparent back plate, an illumination filmstrip, a grating plate, and two step motors with a transmission that drives the grating plate to move. The transparent back plate is fixed onto the inner frame. The illumination filmstrip overlays the transparent back plate and is fixed against it. The two step motors mentioned above are installed on the inner frame behind the upper part or lower part of the transparent back plate, one on the left side, and the other on the right side. The above-mentioned grating plate is fitted with a hanging bar on both the upper side and bottom side respectively, which makes the grating plate spread out neatly. One hanging bar is linked with the transmission of the two above-mentioned step motors through a set of corresponding levers installed on the inner frame. Through this set of levers, the other hanging bar connects with a set of stretch springs that is fitted onto the inner frame behind the transparent back plate. The grating plate spreads out and presses close onto the illumination filmstrip. The illumination case in accordance with the present invention effectively eliminates false images, improves the effect and quality of the illumination case's picture, greatly reduces the width between the top edge and bottom edge of the front cover of the illumination case, and shortens the size of the illumination case.
