Ukuqubuka kweCoronavirus kubeke abantu ekukhathazekeni kokuzungezwa amagciwane, futhi kuthinte kakhulu impilo yansuku zonke yabantu kanye nokusebenza okuvamile komphakathi. Ngenxa yokungcoliswa kwemvelo okwandayo, kwavela ubuchwepheshe bokubulala amagciwane obusebenzisa ukukhanya okujulile kwe-ultraviolet-emitting diode, obuye benza impumelelo enkulu emkhakheni wokubulala amagciwane futhi bunamathuba amaningi emakethe. Ngesikhathi sobhubhane, imikhiqizo ye-UVC LED ultraviolet ibe yimikhiqizo ethengiswa kakhulu yokubulala amagciwane kanye nokubulala amagciwane ngenxa yezinzuzo zayo zobukhulu obuncane, ukusetshenziswa kwamandla aphansi, ubungane bemvelo, kanye nokukhanya okusheshayo.
Ngokukhula komkhakha we-UVC LED, imboni yokunyathelisa nayo iveze ithuba lokuguqulwa nokuthuthukiswa, futhi ngisho nayo yonke imboni yokukhanya kwe-UV iveze ithuba lokuguqulwa nokuthuthukiswa. Ngo-2008, ukubonakala kokuqala kobuchwepheshe bokucwebezela ukukhanya kwe-UV kwe-LED eMbukisweni Wezobuchwepheshe Nemishini Yokunyathelisa waseJalimane i-Drupa kwakumangalisa futhi kwaheha ukunaka okukhulu, kwaheha ukunaka okukhulu kubakhiqizi bemishini yokunyathelisa kanye nabahlinzeki bezinsizakalo zokunyathelisa. Ochwepheshe emakethe yokunyathelisa bancome kakhulu lobu buchwepheshe, futhi bakholelwa ukuthi ubuchwepheshe bokucwebezela ukukhanya kwe-UV kwe-LED buzoba ubuchwepheshe obuyinhloko bokucwebezela embonini yokunyathelisa esikhathini esizayo.
Ubuchwepheshe bokuphulukisa ukukhanya kwe-UV LED
Ubuchwepheshe bokupholisha i-UV LED buyindlela yokuphrinta esebenzisa ama-diode akhipha ukukhanya kwe-UV-LED njengemithombo yokukhanya epholisha. Inezinzuzo zokuphila isikhathi eside, amandla aphezulu, ukusetshenziswa kwamandla aphansi, kanye nokungabi nokungcola (i-mercury). Uma kuqhathaniswa nomthombo wokukhanya we-UV wendabuko (isibani se-mercury), ububanzi obuyisigamu se-spectral se-UV LED buncane kakhulu, futhi amandla azoba agxile kakhulu, ukukhiqizwa kokushisa okuphansi, ukusebenza kahle kwamandla okuphezulu, kanye nokushiswa kwemisebe okufanayo. Ukusetshenziswa komthombo wokukhanya we-UV-LED kunganciphisa ukumoshwa kwezinsiza zokuphrinta futhi kunciphise izindleko zokuphrinta, ngaleyo ndlela konge isikhathi sokukhiqiza amabhizinisi okuphrinta futhi kuthuthukise kakhulu ukusebenza kahle kokukhiqiza kwamabhizinisi.
Kuhle ukusho ukuthi ubuchwepheshe bokwelapha i-UV LED busebenzisa ibhendi ye-ultraviolet ebangeni elisukela ku-365nm kuya ku-405nm, elingelamagagasi amade e-ultraviolet (eyaziwa nangokuthi ibhendi ye-UVA), ngaphandle komonakalo wokushisa, okungenza ubuso be-inki ye-UV bome ngokushesha futhi kuthuthukise ukukhanya komkhiqizo. Ububanzi bamaza obusetshenziswa emkhakheni wokubulala amagciwane e-ultraviolet buphakathi kuka-190nm no-280nm, elingelamagagasi amafushane e-ultraviolet (eyaziwa nangokuthi ibhendi ye-UVC). Leli bhendi lokukhanya kwe-UV ultraviolet lingabhubhisa ngqo isakhiwo se-DNA ne-RNA samaseli namagciwane, futhi libangele ukufa okusheshayo kwama-microorganisms.
Ukusetshenziswa kobuchwepheshe bokwelapha i-UV LED ngabakhiqizi bakwamanye amazwe
I-Aztec Label, ehamba phambili kwezobuchwepheshe be-MicroLED, imemezele ukuthi yakhe futhi yafaka ngempumelelo uhlelo lwayo olukhulu kakhulu lokomisa i-LED UV, oluzoguqula wonke umkhiqizo wayo wefektri ube yilolu hlobo lobuchwepheshe ekupheleni konyaka. Ngemva kokufakwa ngempumelelo kohlelo lokuqala lokwelapha i-LED UV kumshini wokunyathelisa onemibala emibili ngonyaka odlule, inkampani ifaka uhlelo lwesibili lokwelapha i-Benford LED UV endlunkulu yayo yaseWest Midlands ukuze kuncishiswe ukusetshenziswa kwamandla.
Ngokuvamile, ukusetshenziswa kobuchwepheshe bokuphrinta be-LED UV kungenza uyinki wome ngokushesha. Isibani se-LED UV sohlelo lwe-Aztec Label singavulwa futhi sivalwe ngokushesha, akukho sikhathi sokupholisa esidingekayo, futhi senziwe nge-LED UV diode, ngakho-ke impilo yesevisi elindelekile yemishini yayo ingafinyelela emahoreni ayi-10,000-15,000.
Njengamanje, ukonga amandla kanye "ne-dual carbon" sekuba ngenye yezindlela ezibalulekile zokuthuthukisa izimboni ezinkulu. UColin Le Gresley, umphathi jikelele we-Aztec Label, naye ugcizelele ukugxila kwenkampani kulo mkhuba, echaza ukuthi "ukusimama empeleni kuba yinto ehlukanisayo emabhizinisini kanye nesidingo esiyinhloko samakhasimende okugcina".
UColin Le Gresley uphinde waveza ukuthi maqondana nekhwalithi, imishini emisha ye-Benford Environmental LED UV ingaletha imiphumela yokunyathelisa engabizi kakhulu kanye nemibala ecacile, okwenza ikhwalithi yokunyathelisa ihlale izinzile futhi ingenazo izimpawu. “Ngokombono wokuzinza, isebenzisa amandla amancane kakhulu, ingaphansi ngamaphesenti angaphezu kwama-60 kunokomisa kwe-UV okuvamile. Uma ihambisana nokushintsha okusheshayo, ama-diode ahlala isikhathi eside kanye nokukhishwa kokushisa okuphansi, inikeza amakhasimende ukusebenza okuphezulu akulindele ezingeni, ngenkathi ihambisana kahle nemigomo yethu yokuzinza.”
Selokhu kwafakwa uhlelo lokuqala lweBenford, i-Aztec Label ihlabeke umxhwele ngomklamo wayo olula, ophephile kanye nemiphumela yokusebenza. Njengamanje, inkampani inqume ukufaka uhlelo lwesibili, olukhulu.
Isifinyezo
Okokuqala, ngokuvunyelwa nokuqaliswa kwe-"Minamata Convention" ngo-2016, ukukhiqizwa nokungeniswa kanye nokuthunyelwa kwemikhiqizo equkethe i-mercury kuzovinjelwa kusukela ngo-2020 (iningi lokukhanya kwe-UV okuvamile kusebenzisa izibani ze-mercury). Ngaphezu kwalokho, ngoSepthemba 22, 2020, iShayina yabeka isibonelo esimisweni sama-75 se-United Nations General Assembly yethule inkulumo ethi "i-carbon peak kanye nokungathathi hlangothi kwe-carbon" amabhizinisi aseShayina azohlose ukunciphisa ukusetshenziswa kwamandla nokuthuthukisa ukusebenza kahle, futhi aqaphele ukuguqulwa kwedijithali nokuhlakanipha kwamabhizinisi. Ngokuqhubeka okuqhubekayo kobuchwepheshe bokuphrinta kanye nokuthuthukiswa kokuvikelwa kwemvelo embonini yokuphrinta esikhathini esizayo, ubuchwepheshe bokuphrinta be-UV-LED buzoqhubeka nokuvuthwa, okuzosiza imboni yokuphrinta ukuthi iguquke futhi ithuthukise futhi ithuthuke ngamandla.
