ABSTRACT:
An electrically activated light emitting cylindrical or other shaped composite filament. A core conductor is optionally surrounded by a first optional insulation layer, surrounded by an outer electrode and an electroluminescent phosphor. The entire assembly may be coated with a second insulation layer. Light is produced by the phosphor when the core conductor and the outer electrode 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.
