Title

(EN) HIGHLY EFFICIENT UV C BULB WITH MULTIFACETED FILTER

(FR) AMPOULE UV C HAUTEMENT EFFICACE AYANT UN FILTRE À FACETTES MULTIPLES

Abstract

(EN) A Far UV C excimer bulb assembly including an excimer bulb, and at least two filters. The excimer bulb emits a path of light in at least two wavelengths. The at least two filters remove all wavelengths of light that are hazardous to human tissue. The at least two filters may each be placed perpendicular to the path of the light generated by the excimer bulb. The at least two filters may be a single, curved or cylindrical filter. The assembly may further include a mirror which may also be curved.

(FR) Ensemble ampoule à excimères à UV C lointain comprenant une ampoule à excimères, et au moins deux filtres. L’ampoule à excimères émet un trajet de lumière selon au moins deux longueurs d’ondes. Lesdits filtres retirent toutes les longueurs d’ondes de lumière qui sont dangereuses pour le tissu humain. Lesdits filtres peuvent chacun être placés perpendiculaires au trajet de la lumière générée par l’ampoule à excimères. Lesdits filtres peuvent être un filtre unique, incurvé ou cylindrique. L’ensemble peut en outre comprendre un miroir qui peut également être incurvé.
