Title
(EN) 234 NM FAR UV C FILTER
(FR) FILTRE ANTI-UV LOINTAIN À 234 NM
Abstract
(EN) An excimer bulb assembly including an excimer bulb and a pass filter such that the excimer bulb assembly does not emit substantial UV radiation in wavelengths longer than 231nm, 232nm, 233nm, 234nm or 235nm. The wavelengths are measured at an incident angle of zero (0) degrees to the filter plane. The pass filter is preferably constructed of a plurality of layers of hafnium oxide, and most preferably constructed of less than seventy five (75) layers of hafnium oxide. The excimer bulb, pass filter, and two electrical connectors may be adapted to form a cartridge which may be adapted to swivel along its main axis. The cartridge may further include a smart chip. The smart chip may retain and store information regarding the assembly and preferably retains hours of use of the excimer bulb.
(FR) La présente invention concerne un ensemble ampoule à excimères comprenant une ampoule à excimères et un filtre passe-bande de sorte que l'ensemble ampoule à excimères n'émet pas de rayonnement UV important dans des longueurs d'onde supérieures à 231 nm, 232 nm, 233 nm, 234 nm ou 235 nm. Les longueurs d'onde sont mesurées selon un angle d'incidence de zéro (0) degré par rapport au plan de filtre. Le filtre passe-bande est de préférence constitué d'une pluralité de couches d'oxyde d'hafnium, et idéalement constitué de moins de soixante-quinze (75) couches d'oxyde d'hafnium. L'ampoule à excimères, le filtre passe-bande et deux connecteurs électriques peuvent être conçus pour former une cartouche qui peut être adaptée pour pivoter le long de son axe principal. La cartouche peut en outre comprendre une puce intelligente. La puce intelligente peut retenir et stocker les informations concernant l'ensemble et retient de préférence les heures d'utilisation de l'ampoule à excimères.
