Ib xyoos dhau los txij li thaum muaj tus kab mob COVID-2019 kis thoob plaws. Xyoo 2020, tib neeg thoob plaws ntiaj teb nyob hauv ib qho chaw muaj kev sib kis txaus ntshai heev. Raws li cov ntaub ntawv tshaj tawm los ntawm Johns Hopkins University hauv Tebchaws Meskas, txij li 23:22 thaum Lub Ib Hlis 18, lub sijhawm Beijing, Tus lej ntawm cov neeg mob uas tau lees paub tias muaj tus kab mob ntsws tshiab thoob ntiaj teb tau nce mus txog 95,155,602, ntawm cov uas muaj 2,033,072 tus neeg tuag. Tom qab tus kab mob no, tag nrho lub zej zog tau nce nws txoj kev paub txog kev noj qab haus huv, thiab qhov xwm txheej ntawm kev lag luam tua kab mob thiab ntxuav hauv kev tiv thaiv tib neeg lub neej thiab kev noj qab haus huv tau zoo dua. Ntawm lawv, ultraviolet LED sterilization, ua ib txoj hauv kev tiv thaiv kev tua kab mob, kuj tau ua kom nrawm dua ntawm kev loj hlob vim yog qhov kev sib kis ntawm tus kab mob.
Kev tua kab mob ultraviolet yog ib txoj kev ib txwm muaj thiab ua tau zoo. Thaum lub sijhawm SARS, cov kws tshaj lij los ntawm Lub Tsev Haujlwm Saib Xyuas Kab Mob thiab Tiv Thaiv Kab Mob ntawm Lub Chaw Tswj thiab Tiv Thaiv Kab Mob Suav tau pom tias kev siv cov teeb ultraviolet nrog lub zog ntau dua 90μW / cm2 rau 30 feeb los irradiate tus kab mob coronavirus tuaj yeem tua tus kab mob SARS. "Txoj Kev Npaj Kho Mob Pneumonia Tshiab Coronavirus (Trial Version 5)" tau taw qhia tias tus kab mob coronavirus tshiab rhiab heev rau lub teeb ultraviolet. Tsis ntev los no, Nichia Chemical Industry Co., Ltd. tau tshaj tawm tias hauv kev sim siv 280nm tob ultraviolet LEDs, nws tau lees paub tias tus kab mob coronavirus tshiab (SARS-CoV-2) tua hluav taws tom qab 30 vib nas this ntawm kev irradiation ultraviolet tob yog 99.99%. Yog li ntawd, hauv kev xav, kev siv lub teeb ultraviolet kev tshawb fawb thiab kev siv lub tswv yim tuaj yeem ua rau tus kab mob coronavirus tsis ua haujlwm zoo.
Los ntawm qhov kev pom ntawm daim ntawv thov tam sim no, cov LEDs ultraviolet tob tob siv dav hauv cov teb pej xeem xws li kev ntxuav dej, kev ntxuav huab cua, kev tua kab mob ntawm qhov chaw, thiab kev tshawb pom txog kab mob. Tsis tas li ntawd, kev siv cov teeb pom kev zoo ultraviolet ntau dua li kev tua kab mob thiab kev tua kab mob. Nws kuj muaj kev cia siab dav hauv ntau qhov chaw tshiab xws li kev tshawb pom biochemical, kev tua kab mob thiab kev kho mob, kev kho polymer thiab kev lag luam photocatalysis.
Vim muaj peev xwm siv tau ntau yam ntawm cov teeb ci ultraviolet tob tob, LED teeb ci ultraviolet tob tob no muaj peev xwm tsim tau ib qho kev lag luam tshiab uas txawv ntawm LED teeb pom kev zoo hauv xyoo 2021. Vim LED muaj qhov zoo ntawm me me thiab yooj yim nqa tau, zoo rau ib puag ncig thiab muaj kev nyab xeeb, yooj yim tsim thiab tsis muaj teeb pom kev qeeb, kev siv LED teeb ci ultraviolet tob tob no yooj yim dua rau kev nthuav dav mus rau cov khoom siv hluav taws xob tua kab mob, xws li lub tshuab tua kab mob rau niam thiab menyuam, lub tshuab tua kab mob ntawm lub tshuab nqa, lub tshuab ntxhua khaub ncaws me me uas muaj teeb UV Germicidal, cov neeg hlau ntxuav, thiab lwm yam. Piv nrog cov teeb ci ultraviolet mercury, UVC-LED muaj zog ntau dua, uas yooj yim siv rau hauv qhov chaw me me. Nws tuaj yeem nyob ua ke nrog tib neeg thiab tshuab. Nws kov yeej qhov tsis zoo ntawm tib neeg thiab tsiaj txhu uas yuav tsum tau muab tshem tawm thaum lub sijhawm ua haujlwm ntawm cov teeb ci ultraviolet mercury ib txwm muaj. Cov ntawv thov UVC-LED muaj qhov chaw siv loj heev yav tom ntej.
