ABSTRACT:
The present invention is directed to a decorative item. The decorative item includes a number of components which cooperate together. A layer of luminescent material is provided. The layer of luminescent material is preferably, but not necessarily, a substantially rigid and planar carrier. A translucent image is affixed to the layer of luminescent material. The decorative item is operable in a plurality of modes of operation, including an excitation mode of operation and a delayed light emission mode of operation. During the excitation mode of operation, the decorative item is exposed to a source of exciting energy, such as light. In the delayed light emission mode of operation, the layer of luminescent material generates a phosphorescent light emission, after the source of exciting energy is removed, which passes through the translucent image and makes it visible in low light conditions.
