Cishe eminyakeni eyishumi ngemva kokwethulwa kwabo, uyinki we-UV LED olaphekayo usetshenziswa ngesivinini esisheshayo ngabaguquli belebula. Izinzuzo zeyinki ngaphezu koyinki we-UV we-mercury 'ojwayelekile' - ukuqina okungcono nokusheshayo, ukusimama okuthuthukisiwe kanye nezindleko zokusebenza eziphansi - ziya ngokuya ziqondakala kabanzi. Ngaphezu kwalokho, ubuchwepheshe buya ngokuya bufinyeleleka kalula njengoba abakhiqizi bezindaba benikela ngokufaka uhla olubanzi lwezibani ezihlala isikhathi eside emigqeni yabo.
Ngaphezu kwalokho, kunesisusa esikhulu sokuba abaguquli bacabangele ukushintshela ku-LED, ngoba izingozi nezindleko zokwenza kanjalo ziyancipha. Lokhu kwenziwa lula ukufika kwesizukulwane esisha sama-inki kanye nezingubo 'ezimbili' ezingasebenza ngaphansi kwezibani ze-LED neze-mercury, okuvumela abaguquli ukuthi bamukele ubuchwepheshe ngezinyathelo, kunokuba kungazelelwe.
Umehluko omkhulu phakathi kwesibani se-mercury esivamile nesibani se-LED ubude bamaza obukhishwa ukuze kukhanye. Isibani se-mercury-vapor sikhipha amandla ku-spectrum ephakathi kwama-nanometer angu-220 no-400 (nm), kuyilapho izibani ze-LED zinobude bamaza obuncane obuphakathi kwama-375nm no-410nm futhi bufinyelela cishe kuma-395nm.
Ama-inki e-UV LED aqiniswa ngendlela efanayo nama-inki e-UV avamile, kodwa azwela ubude obuncane bokukhanya. Ngakho-ke, ahlukile komunye nomunye ngeqembu lama-photoinitiators asetshenziswa ukuqala ukusabela kokwelapha; ama-pigment, ama-oligomer nama-monomers asetshenziswayo ayafana.
Ukwelashwa kwe-UV LED kunikeza izinzuzo eziqinile zemvelo, ikhwalithi, kanye nokuphepha kunokwelashwa okuvamile. Le nqubo ayisebenzisi i-mercury noma i-ozone, ngakho-ke akukho simiso sokukhipha esidingekayo ukuze kususwe i-ozone emshinini wokunyathelisa.
Iphinde inikeze ukusebenza kahle kwesikhathi eside. Isibani se-LED singavulwa futhi sivalwe ngaphandle kwesidingo sokufudumeza noma isikhathi sokuphola, okunikeza ukusebenza okuhle kakhulu kusukela ngesikhathi sivulwa. Asikho isidingo sama-shutter ukuvikela i-substrate uma isibani sivaliwe.
