Abstract

L'invention concerne un ensemble irradiation (100) pour irradier un fluide avec une lumière ultraviolette, comprenant un boîtier (103) avec un intérieur de boîtier (105), un canal de fluide (109) étant formé dans l'intérieur de boîtier (105) afin de conduire le fluide le long d'une direction d'écoulement (107) ; un moyen d'éclairage (111) qui est conçu pour exposer le canal de fluide (109) à la lumière ultraviolette, ledit moyen d'éclairage (111) étant disposé le long du canal de fluide (109) ; une lentille de collimation (113) qui est disposée en aval du moyen d'éclairage (111) et délimite latéralement le canal de fluide (109), ladite lentille de collimation (113) étant conçue pour collimater la lumière émise par le moyen d'éclairage (111) ; et un réflecteur de lumière (115) qui est disposé à l'opposé de la lentille de collimation (113) et conçu pour réfléchir la lumière ultraviolette collimatée par la lentille de collimation (113) ; le canal de fluide (109) étant délimité latéralement par la lentille de collimation (113) et le réflecteur de lumière (115).
