An electrically activated light emitting cylindrical or other shaped composite filament. A core conductor (401) is optionally surrounded by a first optional insulation layer (402) surrounded by an outer electrode (403) and an electroluminescent phosphor (404). The entire assembly may be coated with a second insulation layer (406). Light is produced by the phosphor when the core conductor (401) and the outer electrode (403) are connected to and energized by an appropriate electrical power supply. The filament may be used to form various one-, two- and three-dimensional light emitting objects.

Filament composite de forme cylindrique ou autre émettant de la lumière et électriquement excité. Un conducteur central (401) est éventuellement entouré par une première couche (402) isolante éventuelle entourée par une électrode externe (403) et un phosphore électroluminescent (404). L'ensemble peut être recouvert d'une seconde couche isolante (406). Le phosphore produit de la lumière lorsque le conducteur central (401) et l'électrode externe (403) sont connectés à une source de courant électrique appropriée ou excités par ledit courant. Ledit filament peut être utilisé pour former différents objets émettant de la lumière, à une, deux ou trois dimensions.
