Abstract

La présente invention concerne un procédé pour effectuer une désinfection d'une pluralité d'objets à l'aide d'une chambre UV renforcée 100, lequel procédé consiste à recevoir des objets dans un tiroir (104) pour effectuer une désinfection, à agencer dans des cavités (a) un actionneur mobile (302) qui est configuré pour se déplacer selon au moins un axe pour éclairer un espace occupé par les objets, et (b) au moins une source de lumière UV (206) montée sur l'actionneur mobile (302), à allumer ou à éteindre la source de lumière UV (206) et à permettre le déplacement de l'actionneur mobile (302) à l'aide d'un dispositif de commande (202) qui comprend un détecteur qui détecte si le tiroir (104) est ouvert ou fermé, et à identifier une présence des objets à l'aide d'un algorithme de traitement d'image, sur la base d'une caméra (304) ou d'un capteur de détection d'objet, pour commander un déplacement de l'au moins une source de lumière UV (206) à l'aide de l'au moins un actionneur mobile (302).
