Abstract

L'invention porte sur un dispositif pour irradier une matière sensible à la lumière. Le dispositif comprend une chambre d'activation ayant une partie de surface arrière interne, une partie de surface avant interne et une partie de surface latérale interne reliant les parties de surfaces avant et arrière internes. Une matière sensible à la lumière est disposée dans la chambre d'activation, la matière sensible à la lumière étant appliquée au moins partiellement sur la partie des surface arrière interne, et une ou plusieurs sources de lumière étant agencées pour irradier la matière sensible à la lumière dans la chambre d'activation, la ou les sources de lumière précitées étant aptes à émettre une lumière ayant une longueur d'onde se situant dans la plage d'absorption de rayonnement de la matière sensible à la lumière. La matière sensible à la lumière peut en outre être appliquée au moins partiellement sur la partie de surface latérale interne. La matière sensible à la lumière peut également être appliquée au moins partiellement sur la partie de surface avant interne. Conformément à un mode de réalisation de l'invention, la chambre d'activation peut avoir une entrée de gaz et une sortie de gaz, permettant ainsi de former un dispositif de production d'un oxygène singulet ou d'un écoulement gazeux oxygéné activé par un oxygène singulet. Conformément à un autre mode de réalisation de l'invention, la chambre d'activation peut avoir une sortie de lumière et une première extrémité d'un guide de lumière qui est agencée à la sortie de lumière, ce par quoi une lumière activée peut être obtenue à partir de l'autre extrémité du guide de lumière, permettant ainsi de produire un dispositif pour générer une lumière activée. La ou les sources de lumière peuvent avoir une intensité suffisante pour obtenir une photosensibilisation avec la matière sensible à la lumière, et la ou les sources de lumière peuvent être formées par des diodes électroluminescentes. Les diodes électroluminescentes peuvent être agencées de façon à s'étendre dans la chambre d'activation.
