Sekudlule unyaka owodwa kwaqubuka i-COVID-2019.Ngo-2020, abantu emhlabeni wonke baphila esimweni esiwubhubhane esesabekayo.Ngokwezibalo ezikhishwe yiJohns Hopkins University e-United States, kusukela ngo-23:22 ngoJanuwari 18, isikhathi saseBeijing, Isibalo samacala aqinisekisiwe e-coronary pneumonia emhlabeni wonke senyuke safinyelela ku-95,155,602, okufa kwabangu-2,033,072.Ngemva kwalolu bhubhane, wonke umphakathi ukhulise ukuqwashisa kwawo ngezempilo, futhi isimo semboni yokubulala amagciwane kanye nokuhlanza ekuvikeleni izimpilo nempilo yabantu ngokungangabazeki sesithuthukile.Phakathi kwazo, inzalo ye-ultraviolet LED, njengendlela yokuvikela amagciwane, nayo yasheshisa ijubane lokukhula ngenxa ye-catalysis yalolu bhubhane.
Ukukhipha amagciwane nge-ultraviolet kuyindlela yendabuko futhi ephumelelayo.Ngesikhathi sakwa-SARS, ochwepheshe be-Institute of Viral Disease Control and Prevention of the Chinese Center for Disease Control and Prevention bathola ukuthi ukusetshenziswa kwemisebe ye-ultraviolet enamandla angaphezu kuka-90μW/cm2 imizuzu engama-30 ukukhanyisela i-coronavirus kungabulala i-SARS. igciwane."I-New Coronavirus Infection Pneumonia Diagnosis and Treatment Plan (Trial Version 5)" iveze ukuthi i-coronavirus entsha iyazwela ekukhanyeni kwe-ultraviolet.Muva nje, i-Nichia Chemical Industry Co., Ltd. imemezele ukuthi ocwaningweni olusebenzisa ama-LED e-ultraviolet ajulile angama-280nm, kuqinisekisiwe ukuthi umphumela wokucisha umlilo omusha we-coronavirus (SARS-CoV-2) ngemuva kwemizuzwana engama-30 yokukhanya okujulile kwe-ultraviolet ubungu-99.99%.Ngakho-ke, ngokombono, ukusetshenziswa kwesayensi nokunengqondo kokukhanya kwe-ultraviolet kungayekisa ukusebenza kwe-coronavirus.
Ngokombono wamanje wohlelo lokusebenza, ama-LED ajulile e-ultraviolet asetshenziswa kakhulu ezindaweni ezivamile ezifana nokuhlanzwa kwamanzi, ukuhlanzwa komoya, ukukhipha amagciwane ebusweni, nokutholwa kwezinto eziphilayo.Ngaphezu kwalokho, ukusetshenziswa kwemithombo yokukhanya kwe-ultraviolet kungaphezu kokuvala inzalo nokubulala amagciwane.Futhi inamathemba abanzi emikhakheni eminingi esafufusa njengokutholwa kwamakhemikhali ezinto eziphilayo, ukuvala inzalo nokwelashwa, ukwelapha nge-polymer kanye ne-photocatalysis yezimboni.
Ngokusekelwe emandleni amakhulu okusebenza kwe-ultraviolet ejulile, i-ultraviolet LED ejulile ingenzeka ngokuphelele ukuthi ithuthuke ibe imboni yezinga lezigidigidi entsha ehlukile ekukhanyeni kwe-LED ngo-2021. Njengoba i-LED inezinzuzo ezincane neziphathwayo, ezinobungani nemvelo futhi ziphephile, kulula ukuyiklama. futhi akukho ukukhanya okulibazisekayo, ukusetshenziswa kwe-ultraviolet LED ejulile kulula ukunwetshwa emikhiqizweni ye-elekthronikhi ephathwayo yokubulala amagciwane, njengesibulala-magciwane sikamama nengane, isibulala-magciwane se-elevator handrail, umshini wokuwasha omncane owakhelwe ngaphakathi amalambu e-UV Germicidal, amarobhothi ashanelayo, njll. Uma kuqhathaniswa ne I-mercury lamp ultraviolet izibani, i-UVC-LED inomthamo omkhulu wamandla, olungele ukusetshenziswa ezindaweni ezincane ezivaliwe.Ingahlala nomuntu nomshini.Inqoba ukushiyeka kwabantu nezilwane okumelwe zithululwe ngesikhathi sokusebenza kwezibani ze-mercury zendabuko ze-ultraviolet.Izinhlelo zokusebenza ze-UVC -LED zinendawo enkulu yohlelo lokusebenza maduze nje.
