Abstract: An illuminating system is provided for objects such as Christmas trees, decorations, works of art and ornaments. Electrically operated, light-emitting elements are hung on or fastened to or within these objects. The light-emitting elements include an electrical oscillatory circuit which can include, for example, inductive and capacitive elements. An energy source powers the elements with direct connection by way of electromagnetic waves or infrared light. The energy source can take the form of, for example, a high-frequency transmitter or an infrared radiation source.
