A light box includes a light passing cover printed with an image. The image is being logically divided into two-dimension blocks. The light box includes multiple light tubes. Each light tube includes a tubular housing, an elongated LED bar, and a controller. The elongated LED bar is being enclosed by the tubular housing. The elongated LED bar has multiple LED modules divided into multiple LED sections. The multiple light tubes is being disposed behind the image of the light passing cover. The multiple LED sections of multiple light tubes is being corresponding to the two-dimension blocks of the image respectively. The controller controls the multiple LED sections separately according to a stored script. The stored script indicate a timing sequence for controlling the multiple LED sections for illuminating the two-dimension blocks of the image according to the stored script.
