Title (EN) ELECTROLUMINESCENT LIGHT SOURCE
(FR) SOURCE DE LUMIERE ELECTROLUMINESCENTE
Abstract:
(EN) 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.
(FR) L'invention concerne une source de lumière constituée par au moins un filament électroluminescent, du type câble, chaque filament possédant une électrode centrale (2) entourée par une couche diélectrique (4) isolante électriquement et par une couche (6) constituée par un mélange d'une poudre électroluminescente et d'un liant. Le mélange est appliqué à la couche diélectrique (4). La source de lumière comprend également une électrode transparente (8) entourant la couche de mélange (6). Les pores formés dans la couche de mélange (6) sont remplis par une substance de charge transparente. L'invention concerne également un procédé de préparation de cette source de lumière.
