Sele kudlule unyaka emva kokuqhambuka kwe-COVID-2019.Ngowama-2020, abantu kwihlabathi liphela bahlala kwindawo eyoyikisayo yobhubhani.Ngokwezibalo ezikhutshwe yiYunivesithi yaseJohns Hopkins e-United States, ukusukela nge-23:22 nge-18 kaJanuwari, ixesha laseBeijing, Inani lamatyala aqinisekisiweyo e-coronary pneumonia entsha kwihlabathi liphela lenyuke laya kutsho kwi-95,155,602, apho kwasweleka abangama-2,033,072.Emva kolu bhubhani, uluntu lonke luye lwandisa ulwazi lwalo ngezempilo, kwaye imeko yeshishini lokubulala iintsholongwane kunye nelokucoca ekukhuseleni ubomi kunye nempilo yabantu ngokungathandabuzekiyo liye laphucuka.Phakathi kwabo, inzalo ye-ultraviolet ye-LED, njengendlela yokukhusela i-disinfection, ibuye yakhawulezisa isantya sokukhula ngenxa ye-catalysis yobhubhane.
I-Ultraviolet disinfection yindlela yendabuko kunye nesebenzayo.Ngexesha le-SARS, iingcali ezisuka kwiZiko loLawulo lweSifo seNtsholongwane kunye noThintelo lweZiko laseTshayina loLawulo lweSifo kunye noThintelo lwafumanisa ukuba ukusetyenziswa kwemitha ye-ultraviolet ngamandla angaphezu kwama-90μW/cm2 imizuzu engama-30 ukukhupha i-coronavirus kunokubulala i-SARS. intsholongwane."I-New Coronavirus Infection Pneumonia Diagnosis and Treatment Plan (Trial Version 5)" ibonise ukuba i-coronavirus entsha inovelwano kukukhanya kwe-ultraviolet.Kutshanje, i-Nichia Chemical Industry Co., Ltd ibhengeze ukuba kuvavanyo olusebenzisa i-280nm ubunzulu be-ultraviolet LEDs, kwaqinisekiswa ukuba i-coronavirus entsha (i-SARS-CoV-2) isiphumo sokucima umlilo emva kwemizuzwana engama-30 yokukhanya okunzulu kwe-ultraviolet yayingama-99.99%.Ke ngoko, ngokwethiyori, ukusetyenziswa kwenzululwazi kunye nengqiqo yokukhanya kwe-ultraviolet kunokwenza i-coronavirus ingasebenzi.
Ngokwembono yesicelo sangoku, ii-LED ezinzulu ze-ultraviolet zisetyenziswa ngokubanzi kwiindawo ezihlala abantu ezifana nokucocwa kwamanzi, ukucocwa komoya, ukubulawa kweentsholongwane kumphezulu, kunye nokufunyanwa kwezinto eziphilayo.Ukongeza, ukusetyenziswa kwemithombo yokukhanya kwe-ultraviolet kungaphezulu kakhulu kunokubulala inzala kunye nokubulala iintsholongwane.Ikwanayo namathemba abanzi kumacandelo amaninzi asakhulayo anjengokubhaqwa kwe-biochemical, ukuvala inzala kunye nonyango, ukunyanga i-polymer kunye ne-industrial photocatalysis.
Ngokusekelwe kwisicelo esikhulu esinamandla e-ultraviolet enzulu, i-ultraviolet i-LED enzulu inokwenzeka ngokupheleleyo ukuphuhlisa kwishishini elitsha letriliyoni-level eyahlukileyo ukusuka ekukhanyeni kwe-LED ngo-2021. kwaye akukho ukulibaziseka kokukhanyisa, ukusetyenziswa kwe-ultraviolet LED enzulu kulula ukuba kwandiswe kwiimveliso ze-elektroniki eziphathwayo zokubulala iintsholongwane, ezifana ne-sterilizer kamama kunye nomntwana, i-elevator handrail sterilizer, umatshini wokuhlamba omncinci owakhelwe-kwi-UV Germicidal izibane, iirobhothi ezitshayelayo, njl. Izibane ze-mercury ze-ultraviolet, i-UVC-LED inoxinano lwamandla aphezulu, olulungele ukusetyenziswa kwiindawo ezincinci ezivaliweyo.Inokuhlalisana nomntu kunye nomatshini.Inqoba iintsilelo zabantu kunye nezilwanyana ekufuneka zikhutshwe ngexesha lomsebenzi wezibane zemveli ze-mercury ze-ultraviolet.Izicelo ze-UVC-LED zinendawo enkulu yesicelo kungekudala.
