Abstract

L'invention concerne des systèmes pour la désinfection automatique d'un objet sur une base périodique, utilisant une source de rayonnement (210) telle qu'une lumière ultraviolette intégrée dans ou autrement disposée de façon à émettre un rayonnement sur une surface de l'objet. De préférence, la source de rayonnement (210) est conçue à l'intérieur de l'objet lui-même de telle sorte que l'objet peut être auto-désinfecté périodiquement sans qu'il soit nécessaire de pulvériser ou d'essuyer manuellement l'objet. Ceci permet des cycles de nettoyage fréquents, normalisés, d'écrans d'affichage (208), d'unités de contrôle de passagers et d'autres objets sans nécessiter de main-d'oeuvre et de consommables.
