Chaka chimodzi chadutsa kuyambira pomwe COVID-2019 idayamba.Mu 2020, anthu padziko lonse lapansi akukhala mumlili wowopsa.Malinga ndi ziwerengero zomwe zatulutsidwa ndi yunivesite ya Johns Hopkins ku United States, kuyambira 23:22 pa Januware 18, nthawi ya Beijing, Chiwerengero cha milandu yotsimikizika ya chibayo chatsopano padziko lonse lapansi chakwera mpaka 95,155,602, pomwe 2,033,072 amafa.Pambuyo pa mliriwu, anthu onse awonjezera chidziwitso cha zaumoyo, ndipo momwe makampani ophera tizilombo toyambitsa matenda ndi kuyeretsa poteteza miyoyo ya anthu ndi thanzi lawo mosakayika apita patsogolo.Pakati pawo, kutsekereza kwa ultraviolet LED, monga njira yodzitetezera ku tizilombo toyambitsa matenda, kwathandiziranso kukula kwachangu chifukwa cha mliri wa mliri.
Ultraviolet disinfection ndi njira yachikhalidwe komanso yothandiza.Munthawi ya SARS, akatswiri a Institute of Viral Disease Control and Prevention of the Chinese Center for Disease Control and Prevention adapeza kuti kugwiritsa ntchito cheza cha ultraviolet ndi mphamvu yopitilira 90μW/cm2 kwa mphindi 30 kuti iyambitse coronavirus kumatha kupha SARS. kachilombo."New Coronavirus Infection Pneumonia Diagnosis and Treatment Plan (Trial Version 5)" inanena kuti coronavirus yatsopanoyo imakhudzidwa ndi kuwala kwa ultraviolet.Posachedwa, Nichia Chemical Viwanda Co., Ltd. adalengeza kuti poyesa kugwiritsa ntchito ma 280nm akuya a ultraviolet ma LED, zidatsimikiziridwa kuti chozimitsa moto chatsopano cha coronavirus (SARS-CoV-2) pambuyo pa masekondi 30 akuya kwakuya kwa ultraviolet kunali 99.99%.Chifukwa chake, mwamalingaliro, kugwiritsa ntchito mwasayansi komanso mwanzeru kwa kuwala kwa ultraviolet kumatha kuyambitsa coronavirus.
Malinga ndi zomwe zikuchitika pano, ma LED akuya a ultraviolet amagwiritsidwa ntchito kwambiri m'malo omwe si anthu wamba monga kuyeretsa madzi, kuyeretsa mpweya, kupha tizilombo toyambitsa matenda, komanso kuzindikira kwachilengedwe.Kuphatikiza apo, kugwiritsa ntchito magwero a kuwala kwa ultraviolet ndikochuluka kwambiri kuposa kuthirira komanso kupha tizilombo.Ilinso ndi chiyembekezo chokulirapo m'magawo ambiri omwe akubwera monga kuzindikira kwa biochemical, kutsekereza ndi chithandizo chamankhwala, kuchiritsa kwa polima ndi photocatalysis ya mafakitale.
Kutengera kuthekera kwakukulu kogwiritsa ntchito kwakuya kwakuya kwa ultraviolet, kuya kwa ultraviolet LED ndikothekera kotheratu kukhala makampani atsopano a thililiyoni wosiyana ndi kuyatsa kwa LED mu 2021. Monga LED ili ndi ubwino wazing'ono ndi zonyamula, zachilengedwe komanso zotetezeka, zosavuta kupanga. ndipo osazengereza kuyatsa, kugwiritsa ntchito kwakuya kwakuya kwa ultraviolet LED ndikosavuta kufalikira kuzinthu zamagetsi zamagetsi, monga chowotcha cha amayi ndi ana, chowotcha chowongolera m'mwamba, makina ochapira a mini omangidwa mu UV Germicidal nyali, maloboti akusesa, ndi zina zambiri. nyali ya mercury ultraviolet nyali, UVC-LED imakhala ndi mphamvu zambiri, zomwe ndizosavuta kugwiritsa ntchito m'malo ang'onoang'ono.Ikhoza kukhala limodzi ndi munthu ndi makina.Imagonjetsa zolakwa za anthu ndi nyama zomwe ziyenera kukhuthulidwa panthawi ya ntchito ya nyali yamtundu wa mercury ultraviolet nyali.Mapulogalamu a UVC -LED ali ndi malo akuluakulu ogwiritsira ntchito posachedwa.
