Lezi zinhlelo zihlanganiswe nokuguquguquka, ukusebenza kahle kwamandla, nokukhanya okuphezulu kwe-ultraviolet ukuhlinzeka ngokusebenza okungenakuqhathaniswa nezidingo zokukhiqiza zanamuhla. Kungaba izixazululo zezimboni ze-UV array, i-UV LED array kuma-adhesives, noma i-UV array eguquguqukayo ekugqokeni, ukwamukelwa kwe-UV LED ngokwezifiso kuyindlela eqinisekile yokuqinisekisa ukuphulukiswa okusheshayo kokunamathisela, ukukhishwa kwamandla okulawulwayo, nokwethenjelwa emiphumeleni efanayo kuzicelo ezahlukahlukene. Ulwazi lwe-UV Arrays eyenziwe ngokwezifiso I-UV eklanyelwe ngokwezifiso, ilungiselelo lama-LED e-UV adalwe ukunikeza ukukhanya okufanayo kwe-ultraviolet, okulinganiselwe ngokukhethekile, okubunjiwe, kanye nokuqina okudingekayo ukuhlangabezana nezidingo ezithile zohlelo lokusebenza. Ama-arrays anjalo angahlelwa ukuhlinzeka ngamandla anembile ezindaweni eziyisicaba, izingxenye ezigobile, noma izakhiwo eziyinkimbinkimbi ukuvumela ubuchwepheshe bokuphulukisa ukukhanya kwe-UV ezinhlobonhlobo zezinhlelo zokusebenza zezimboni. Ngokungafani nezibani ezijwayelekile ze-UV ezine-mercury, ama-UV LED angokwezifiso anawo: Izixazululo ze-COB LED ultraviolet (ukupakisha kwe-Chip-on-Board) zihlanganisa ama-chips amaningi we-ultraviolet LED anamandla kakhulu ku-substrate eyodwa, ahlinzeka ngokukhanya okuphezulu, imisebe ye-UV efanayo, nokushabalalisa ukushisa okusebenzayo. Lawa ma-COB UV LED abonakala ngokuzinza kokusebenza kwesikhathi eside, okwenza alungele izinhlelo zokusebenza ezifana nokuphulukiswa kwezimboni, ukuphrinta okunemba okuphezulu, ukukhiqizwa kwe-elekthronikhi, nokuvala inzalo kwezokwelapha. COB LED UV Izixazululo zinamasayizi amancane futhi zidla amandla amancane, okwenza imikhiqizo engabizi kakhulu ye-UVET ngokunemba okuqhubekayo kobude be-wavelength ...
