Abstract

La présente invention concerne un dispositif de désinfection d'air capable d'améliorer considérablement un effet de désinfection d'air et de contribuer à la conservation d'énergie.　Ce dispositif de désinfection d'air comporte une source de lumière pour désinfecter l'air, une chambre de désinfection pour loger cette source de lumière, une partie d'introduction pour introduire de l'air dans cette chambre de désinfection, et une partie d'émission pour émettre de l'air à partir de la chambre de désinfection. La chambre de désinfection a trois miroirs plans ou plus disposés successivement et de manière adjacente de façon à encercler la source de lumière.
