1. A lighting module for three-dimensional suspension imaging, comprising a microlens array and a micro image-text element, wherein a transparent medium layer is provided between the microlens array and the micro image-text element, the micro image-text element comprises a micro image-text array corresponding to the microlens array, and the micro image-text element is arranged in such a way that light can be irradiated from the micro image-text array to the microlens array through the transparent medium layer and form a three-dimensional suspended image, and
wherein the micro image-text array comprises a micro image-text layer and a plurality of hollowed-out micro image-texts are arranged on the micro image-text layer;
wherein the micro image-text array, the transparent medium layer, and the microlens array are stacked in sequence to form an image thin film;
wherein, a layer of ultraviolet curing glue is coated on the transparent medium layer, and grooves with a depth greater than 1 micron are embossed on a surface of the ultraviolet curing glue by using a relief block with micro image-texts, and meanwhile cured, and then parts other than the grooves are made opaque.
