"Ib daim ntawv thov loj yog nyob rau hauv cov xwm txheej kho mob -- cov tshuaj tua kab mob ntawm cov cuab yeej tiv thaiv tus kheej, qhov chaw, hauv pem teb, nyob rau hauv HVAC systems, thiab lwm yam," hais tias cov ntaub ntawv kws tshawb fawb kws kho mob Christian Zollner, uas nws lub chaw ua haujlwm rau kev nce qib ntawm ultraviolet lub teeb LED technology. rau sanitation thiab purification lub hom phiaj. Nws hais ntxiv tias lub khw me twb muaj rau cov khoom siv tshuaj tua kab mob UV-C hauv kev kho mob.
Tseeb tiag, ntau qhov kev saib xyuas lig tau tig mus rau lub zog ntawm lub teeb ultraviolet los ua kom tsis muaj tus kabmob tshiab. Raws li kev siv tshuab, kev tua kab mob ultraviolet tau nyob ib puag ncig. Thiab txawm tias qhov ua tau zoo, qhov ua tau zoo ntawm qhov loj ntawm kev sib kis ntawm SARS-CoV-2 tseem tsis tau pom. UV teeb pom kev cog lus ntau: SSLEEC cov tswv cuab lub tuam txhab Seoul Semiconductor thaum ntxov Lub Plaub Hlis tau tshaj tawm "99.9 feem pua ua rau tus mob coronavirus (COVID-19) hauv 30 vib nas this" nrog lawv cov khoom UV LED. Lawv cov thev naus laus zis tam sim no tau raug coj los siv rau kev siv tsheb, hauv UV LED teeb uas ua kom tsis muaj menyuam sab hauv ntawm cov tsheb tsis muaj neeg nyob.
Nws tsim nyog sau cia tias tsis yog txhua qhov UV wavelengths zoo ib yam. UV-A thiab UV-B -- hom peb tau txais ntau ntawm no hauv ntiaj teb kev saib xyuas ntawm lub hnub -- muaj kev siv tseem ceeb, tab sis qhov tsis tshua muaj UV-C yog lub teeb ultraviolet xaiv rau huab cua huv. thiab dej thiab rau inactivating microbes. Cov no tuaj yeem tsim los ntawm tib neeg tsim cov txheej txheem.
"UV-C lub teeb nyob rau hauv 260 -- 285 nm ntau yam cuam tshuam rau cov cuab yeej tshuaj tua kab mob tam sim no kuj ua rau tib neeg cov tawv nqaij, yog li tam sim no nws feem ntau yog siv rau hauv cov ntawv thov uas tsis muaj leej twg nyob rau lub sijhawm tshuaj tua kab mob," Zollner tau hais. . Qhov tseeb tiag, Lub Koom Haum Saib Xyuas Kev Noj Qab Haus Huv (World Health Organization) ceeb toom tawm tsam kev siv cov tshuaj tua kab mob ultraviolet los ntxuav tes lossis lwm qhov chaw ntawm daim tawv nqaij -- txawm tias luv luv rau UV-C teeb tuaj yeem ua rau kub hnyiab thiab qhov muag puas.
Ua ntej COVID-19 kis thoob ntiaj teb tau txais lub zog thoob ntiaj teb, cov kws tshawb fawb cov ntaub ntawv ntawm SSLEEC twb tau ua haujlwm ua ntej UV-C LED thev naus laus zis. Lub cheeb tsam ntawm lub electromagnetic spectrum no yog ib tug tseem tshiab frontier rau solid-state teeb pom kev zoo; UV-C lub teeb yog feem ntau tsim los ntawm mercury vapor teeb thiab, raws li Zollner, "ntau yam thev naus laus zis xav tau rau UV LED kom ncav cuag nws lub peev xwm ntawm kev ua haujlwm, nqi, kev ntseeg siab thiab lub neej."
