Abstract
A light source is used to extend the operating period of light-activated materials in gazing globes and other decorative or ornamental objects. A gazing globe according to the invention includes a hollow glass globe supported on a stand. Photoluminescent, fluorescent or phosphorescent material is deposited on, or embedded in, the globe. A light-emitting diode (LED) is supported within the globe to activate the material. A solar cell is used to charge one or more batteries, and a light detector is used to switch power from the battery to the source of light when a sufficient level of darkness is detected. A violet or ultraviolet LED may be used as the light source, with the solar cell is supported on the stand. The material deposited on, or embedded in, the globe may intentionally glow in a swirling pattern when activated.
