Abstract
Un dispositif d'émission d'UV lointain comprend une enveloppe de lampe contenant une paroi transmettant un rayonnement UV et entourant un espace d'une manière étanche aux gaz.
Ledit espace comprend un remplissage de gaz de décharge. Le dispositif d'émission d'UV lointain comprend en outre une source d'émission d'UVC lointain, par exemple une source de KrCl/KrBr ou une combinaison d'une décharge de Xe avec un luminophore de génération d'UVC lointain, dont l'émission de photons en cours de fonctionnement se situe dans une plage de longueurs d'ondes d'UVC lointain de 200 à 230 nm. Le dispositif d'émission d'UV lointain comprend en outre un luminophore de conversion d'UVC profond situé en aval de la source d'émission d'UVC lointain et ayant un spectre d'excitation dans une plage de longueurs d'ondes d'UVC profond de 230 à 300 nm permettant de convertir un rayonnement de la source d'émission d'UVC lointain émis dans ladite sous-plage d'UVC profond sous la forme d'un rayonnement dans des plages de longueurs d'ondes d'UVB et/ou supérieures en cours de fonctionnement.
Ledit luminophore de conversion d'UVC profond est transmissif pour la plage d'UVC lointain.
