发明名称 Hologram light box
摘要 A light box includes a lower casing and an upper casing pivotally connected to the lower casing. A lighting element is pivotally mounted to the inner side of the lower casing. A plurality of pairs of spaced ridges are provided on both longitudinal sides of the inner periphery of the lower casing. A plate is pivotally received in the inner side of the upper casing at an upper side thereof. The lower side of the plate is selectively supported by one of the pairs of the ridges. A hologram is provided on one side of the plate which faces the lighting element. When the upper casing is opened to a pre-determined extent, the lighting element is switched on. Under adjustment of the inclination of the hologram plate and the lighting element, a viewer may appreciate various images contained in the hologram.
