There is provided a light source consisting of at least one flexible, cable-like electroluminescent filament, each filament having a central electrode (2) surrounded by an electrically insulating dielectric layer (4), and a layer (6) consisting of a mixture of an electroluminophor powder and a binder. The mixture is applied to the dielectric layer (4). The light source also includes a transparent electrode (8) surrounding the mixture layer (6). Pores formed in the mixture layer (6) are filled in by a transparent filler substance. A method for preparing the light source is also provided.

A cable-like electroluminescent light source comprises at least two electrodes mutually disposed in such a way as to create between them an electric field when a voltage is applied to them; at least one type of pulverulent electroluminophor dispersed in a dielectric binder and disposed in such proximity to the electrodes as to be effectively excited by the electric fields when created and to emit light of a specific color, and a transparent polymer sheath encasing the electrodes and the electroluminophor.
