A lighting device configured to deactivate pathogens in an environment. The lighting device includes at least one first light-emitting element (256) configured to emit light having a wavelength of between 400 nm and 420 nm, wherein the light emitted by the at least one first light-emitting element is configured to deactivate the pathogens in the environment. The lighting device also includes at least one second light-emitting element (260) configured to emit light having a wavelength of greater than 420 nm. A first combined light output of the light emitted by the at least one first and the at least one second light-emitting elements includes visible light that is perceived as white light. The white light has properties that make it visually appealing and unobjectionable. La présente invention concerne un dispositif d'éclairage conçu pour désactiver des agents pathogènes dans un environnement. Le dispositif d'éclairage comprend au moins un premier élément électroluminescent (256) conçu pour émettre de la lumière présentant une longueur d'onde comprise entre 400 nm et 420 nm, la lumière émise par le ou les premiers éléments électroluminescents étant conçue pour désactiver les agents pathogènes dans l'environnement. Le dispositif d'éclairage comprend également au moins un second élément électroluminescent (260) conçu pour émettre de la lumière présentant une longueur d'onde supérieure à 420 nm. Une première sortie de lumière combinée de la lumière émise par le ou les premiers éléments électroluminescents et par le ou les seconds éléments électroluminescents comprend une lumière visible qui est perçue comme de la lumière blanche. La lumière blanche affiche des propriétés qui la rendent visuellement attrayante et inoffensive.
