Ubhubhani we-covid-19 ukhulise ulwazi loluntu malunga nokubulala iintsholongwane kwi-UV, ekwabonakaliswa kwinani elandayo leemveliso ezisekwe kwi-LED kwintengiso. Ukukhanya kwe-Ultraviolet kungasetyenziselwa ukubulala iintsholongwane emoyeni, amanzi kunye nomphezulu wezinto ezahlukeneyo. I-International ultraviolet Association (iuva) ithi inokunceda ukunciphisa umngcipheko wokusasaza intsholongwane ye-covid-19. Ukukhanya kweUltraviolet kwahlulwe ngokweendidi ezininzi (Umfanekiso 1). Ukukhanya kwe-UV-A okanye ukukhanya okumnyama ukusuka kwi-315 ukuya kwi-400 nm kwaye isetyenziswa kwizicelo ezifana novavanyo lokuzinza kokukhanya, ukunyanga, ukuthotyelwa kwefoto, ukugxotha izinambuzane kunye neebhedi zokuthambisa. Ukuvezwa ixesha elide kwi-UV-A kunokukhokelela ekukhanyeni kwesikhumba kunye nokuguga kwangaphambi kwexesha.Umfanekiso 1 ukukhanya kwe-ultraviolet kwahlulwe kwiindidi ezininzi.

I-UV-B kuluhlu lwe-wavelength ye-280 ~ 315 nm iyingozi. Ngenxa yokuba ukuvezwa kwexesha elide kwi-UV-B kuhambelana nesiganeko somhlaza wesikhumba, ukuguga kwesikhumba kunye ne-cataract, izicelo zorhwebo ziquka ukugcinwa kunye ne-phototherapy kwiyeza.I-wavelength kuluhlu lwe-200 ~ 280nm yi-UV-C. Le bhanti ye-UV ayinanto yakwenza nomhlaza wolusu kuba iiphotons azingeni nzulu eluswini, kodwa ngokophando lwe-iuva, ukuvezwa kwi-UV-C kunokubangela ukungakhululeki kolusu njengokutsha kakhulu kwaye konakalise iretina yamehlo. Iifotoni ze-UV-C zinokusebenzisana ne-RNA kunye neemolekyuli ze-DNA kwii-microorganisms ukuze zizitshabalalise ngokufanelekileyo. Izibane zomphunga zeMercury ezinokukhupha i-UV-C ziye zasetyenziselwa ukubulala iintsholongwane kangangamashumi eminyaka. Nangona kunjalo, njengezinye iindlela zokukhanyisa, baye batshintshela kwiimveliso zisebenzisa imithombo yokukhanya ye-LED.

Iingcali zezempilo zikholelwa ukuba eyona ndlela iphambili yosulelo lwe-covid-19 kukunxibelelana namathontsi okuphefumla emoyeni okanye kumphezulu wezinto. Ikhoyo ngoku i-LED esekelwe ekubulaleni iintsholongwane kunye neemveliso zokubulala iintsholongwane zisetyenziselwa ukubulala iintsholongwane kumphezulu. Ngokwandiswa kwezi marike zezixhobo, iinkqubo zokubulala iintsholongwane zomoya ezihambele phambili kakhulu kunokwenzeka ukuba zingeniswe. Iimveliso ezifumanekayo zineenzuzo zokufaneleka kwezinye iintlobo zokukhanya kwe-LED: ubungakanani obuncinci, ukudibanisa lula kunye nezinye izixhobo ezifana neenzwa zobukho, kunye neemfuno zokusetyenziswa kwamandla aphantsi. Nangona kunjalo, ezi mveliso zihlala zibiza kakhulu, kwaye kuya kubakho izithintelo ezingaphezulu kuluhlu lweendawo ezingaphezulu ezinokucutshungulwa ngexesha lokwenyani.

Ingqwalasela yokuqala yokutshintsha kwii-LED ibe kukuncitshiswa okubonakalayo kubomi be-LED xa kuthelekiswa nezibane ezikhoyo zomphunga zemercury. Nangona kunjalo, le nkxalabo isekelwe kuvavanyo lokusebenza okuqhubekayo kwizicelo zemveli ezifana neenkqubo zokucoca ezitywiniweyo, kwaye ayithathi ingqalelo ukuba iimveliso ze-bactericidal zinokuthi (kwaye ngamanye amaxesha kufuneka) zisetyenziswe ngokukhawuleza. Njengazo zonke ii-LED, ii-LED ze-UV-C zinokujikeleza phantse ngokungenasiphelo ngaphandle kokuchaphazela kakubi ukuphuma kokukhanya; Ukongeza, isibane somphunga wemercury sidinga imizuzu emininzi yexesha lokufudumeza ukufikelela kowona kukhanya uphezulu, kwaye iimveliso ze-LED ziphantse zifikelele kwinqanaba elipheleleyo lokuphuma ngephanyazo. Ukongeza, ngokungafaniyo nezibane ze-mercury vapor, iimveliso ezikhokelwayo zinokubonelela kuphela ubude obufunekayo kwiziphumo ezilungileyo ngaphandle kokuchitha amandla ngendlela yobude obungavumelekanga.

Ngokuqhelekileyo, enye ingxaki yeemveliso zokukhanyisa izibane kukuqinisekiswa kokhuseleko lwemveliso kunye neemfuno zokusebenza. NgokukaCarl Bloomfield, umlawuli wehlabathi weziseko zophuhliso lweshishini kwishishini lombane le-Intertek, uvavanyo lwabo lwemveliso lugxile kukukhanya okuqaqambileyo, ukuqinisekiswa kwengxelo yokuvala inzala, ukuthotyelwa kokhuseleko kunye ne-EMC esebenzayo. Ii-arhente zophuhliso lwemigangatho sele ziqalisile ukuvavanya imigangatho, kodwa imigangatho ayikabikho, ke i-Intertek ixhomekeke kumzi mveliso kunye nobuchule bobugcisa ukuyila iiprothokholi zovavanyo lweemveliso ezithile kunye nokusetyenziswa kwazo. Ukuthotyelwa kokhuseleko kunokuba nzima ngakumbi kuba kuxhomekeke kwimveliso kunye nokusetyenziswa kwayo ekujoliswe kuyo, kubandakanywa umlilo, ukutshitshiswa kombane, umngcipheko womatshini, iingozi zamehlo, ukuphuma kwe-UV kunye nokukhutshwa kwe-ozone.

Ukongeza kwiimveliso zokubulala iintsholongwane zeUV, kukho uluhlu olutsha lwemveliso olubizwa ngokuba yi "visible light disinfection (VLD)". Ezi mveliso zisebenzisa i-indigo (blue purple) ubude bobude obukhutshwa zii-LEDs, ezikhuselekileyo kumzimba womntu ukuba zibonakale ixesha elide, ukuze ngokuqhubekayo ziphelise iibhaktheriya ezinovakalelo kule wavelengths.VLD iimveliso zidla ngokufakwa kwindawo njengenxalenye ye ukuphunyezwa kokukhanyisa okusisigxina, kwaye ngamanye amaxesha kusetyenziswa ngokudibanisa nemithombo yokukhanya okumhlophe yokukhanyisa ngokubanzi. Kuyafaneleka ukuqaphela ukuba i-VLD yokubulala iintsholongwane ayisebenzi kuzo zonke iibhaktheriya kwaye ayisebenzi ngokupheleleyo kwiintsholongwane.
