Le fil conducteur (22) est connecté au pôle négatif d'une alimentation électrique et l'âme conductrice (21) est connectée au pôle positif de l'alimentation électrique. Une couche de mélange de couleurs (21) présentant une pluralité de couleurs est disposée entre la couche isolante transparente (24) et la couche de protection transparente (26). La couche luminescente (23) est une couche de revêtement en poudre luminescente sur une surface de l'âme conductrice (21). Le filament électroluminescent présente l'avantage d'un coût faible et d'une mise en forme aisée, et les matières premières de celui-ci sont aisées à acheter. Il surmonte également l'inconvénient de la feuille électroluminescente, à laquelle on ne peut pas donner une forme ronde.
