GG quot; Hauv kev tiv thaiv thiab tswj hwm tus tshiab cov kabmob hnoos hawbpob tau kis, UV yog tus qauv uas tau lees paub, thiab daim ntawv thov kev cia siab ntawm kev sib sib zog nqus UV LED nyob rau hauv kev noj qab haus huv tseem tau txais kev saib xyuas dav." Wu Ling, tus thawj coj ntawm National Semiconductor Teeb Txheem Engineering R& D thiab Kev Lag Luam Sib Koom Tes Hauv kev sib tham tsis ntev los no, qhia tus kws xov xwm ntawm Science thiab Technology Txhua Hnub.
Ultraviolet thev naus laus zis thev naus laus zis muaj keeb kwm ntau dua 100 xyoo. Nws tau to taub tias, ntxiv rau nqus ultraviolet, sib sib zog nqus ultraviolet yog qhov luv tshaj nthwv dej thiab lub zog siab tshaj plaws hauv ultraviolet band. Nws muaj qhov ua kom ncaj thiab kom tsis muaj menyuam. Nws yog tsuas yog siv hauv dej thiab huab cua huv, kev ua kom tsis muaj menyuam, thiab kev tshawb pom lom.
Li Jinmin, tus Thawj Coj ntawm Lub Xeev Tshawb Xyuas Kev Tshawb Fawb Txog Kev Tshawb Fawb Txog Kev Tshawb Fawb Txog Kev Tshawb Fawb Txog Kev Tsim Kho, hais tias feem ntau ntawm kev sib sib zog nqus ultraviolet teeb pom kev zoo siv nyob rau kev siv tshuaj tua kab mob thiab ua kom tsis muaj kabmob hauv cov haujlwm pej xeem thiab cov chaw lag luam yog cov teeb tsa roj. Vim tias muaj cuam tshuam los ntawm cov mercury rau cov tib neeg thoob plaws ntiaj teb thiab ib puag ncig, pib lub xyoo no, International Minamata Cov Lus Cog Tseg, uas txwv tsis pub siv thiab tso tawm cov mercury, tau nkag rau hauv lub zog. Cov teeb tsa tshuaj pleev ib ce tso tawm yuav raug txwv, txwv tsis pub siv thiab siv, thiab maj mam rho tawm los ntawm kev ua lag luam. Kev tsim kho hom tshiab ntawm cov phooj ywg ib puag ncig thiab txuag hluav taws xob UV teeb ci tau dhau los ua qhov kev sib tw tseem ceeb rau tib neeg.
GG quot; Sib sib zog nqus UV LED nyob rau tiam thib peb ntawm GaN cov khoom siv hluav taws xob tau dhau los ua qhov kev xaiv zoo tshaj rau daim ntawv thov tshiab no. Tag nrho cov teeb pom kev zoo lub xeev no muaj qhov me me, kev ua haujlwm siab, thiab lub neej ntev. Nws tsuas yog chip nti qhov luaj li cas ntawm cov ntiv tes xoo npog. Nws emits ultraviolet lub teeb muaj zog dua li cov teeb meem muaj muaj txiaj ntsig," hais Li Jinmin.
Nws tau nkag siab tias SARS tiv thaiv thiab kis kab mob ntawm Tuam Tsev Tshawb Nrhiav thiab Tiv Thaiv Kab Mob Suav Tebchaws tau tshawb pom tias tus kab mob SARS tuaj yeem tua los ntawm kev cuam tshuam cov kabmob coronavirus rau 30 feeb nrog lub teeb ci ultraviolet muaj qhov siv ntau dua 90 μW / cm2 (microwatts / cm2 ))." Kev kuaj mob ntsws thiab kev kho mob rau Kab Mob Tshiab ntawm Kab Mob Coronavirus (Kev Sim Tshooj 6)" hais tias qhov mob tshiab coronavirus yog rhiab rau ultraviolet rays. Wu Ling qhia tias hauv kev tiv thaiv kev tiv thaiv kabmob thiab kev tswj hwm, muaj kwv yees peb hom kev sib sib zog nqus UV LED cov khoom lag luam uas tau siv dav: cov khoom siv ua kom tsis huv saum npoo av, xws li ntau cov kev ua haujlwm kom tsis muaj menyuam, thiab lwm yam; portable portable kom tsis muaj menyuam cov khoom siv, xws li cov ntoo ua kom tsis muaj menyuam, lub thawv kom tsis muaj menyuam, thiab lwm yam; Kev sib sib zog nqus UV LED cua kom tsis muaj menyuam thiab cov khoom siv ua kom huv, xws li humidifier, dehumidifier, phab ntsa-mounted UV sterilizer thiab lwm yam.
GG quot; Cov ntawv thov tso cai rau kev lag luam tshawb nrhiav ntau daim ntawv thov thiab cov lus qhia tsim cov khoom lag luam." Wu Ling tau hais.
Li Jinmin tau hais tias yog sib sib zog nqus UV LED yog los hloov cov teeb meem mercury, nws txhais tau tias nyob rau xyoo kaum xyoo tom ntej no, kev sib sib zog nqus UV kev lag luam yuav dhau los ua kev lag luam tshiab vam txog nyiaj daus las zoo li LED teeb pom kev zoo.
Tab sis kev cov nyom thiab cov hauv kev muaj nyob. Kev sib sib zog nqus UV LED yog thev naus laus zis uas tsuas yog tsim thaum pib ntawm lub xyoo pua no. Nws tseem nyob rau theem pib ntawm kev tsim khoom, thiab nws lub zog hluav taws xob, kev siv hluav taws xob, thiab lub neej tsis txaus siab. Daim ntawv thov thiab txhawb cov khoom lag luam yog txwv los ntawm kev ua kom tsis muaj menyuam thiab tua kab mob, uas tsis yog qhov paub tsis meej, thiab kev hloov pauv ntawm cov khoom siv hluav taws xob muaj roj tsawg tsawg uas muaj nyob hauv lub teeb tseem raug txwv los ntawm theem kev txhim kho thev naus laus zis. Nws tsis yooj yim rau lawv nyiam.
Li Jinmin taw qhia tias sib sib zog nqus UV LED tseem ntsib ntau yam kev sib tw los ntawm cov khoom siv tseem ceeb mus rau kev siv cuab yeej technology ntawm qib theem, thiab kev thev naus laus zis thiab kev ua tiav yog lub hauv paus ntawm kev tsim kho kev lag luam.
Wu Ling ntseeg tias dab tsi yuav tsum ua kom tiav yog qhov tsis muaj cov qauv. Muaj cov qauv UV ntau yog nyob raws cov teeb meem siv hluav taws xob ib txwm nyob. UV LED lub teeb ci tau xav tau ceev cov qauv ntawm kev sim los ntawm kev thov.
GG quot; Txhawm rau sau qhov tsis muaj dab tsi ntawm kev ua haujlwm, Lub Tuam Txhab Pab Pawg Sib Koom Tes tau siv qhov kev teb tau sai ntawm cov qauv pab pawg rau kev xav tau kev ua lag luam, ua cov kev soj ntsuam ntawm ntsuas, ntsuas, ntsuas, thiab lwm yam, nquag siv cov txheej txheem qauv, npaj kev" UV LED Cov Txheej Txheem Tshaj Tawm Txheej Txheem Tshaj Tawm", thiab tshaj tawm" UV LED Technology thiab Cov Lus Siv thiab Cov Lus Txhais" thiab" UV LED Sterilization thiab Disinfection Technology Qhia" yuav maj mam tsim cov txheej txheem qauv uas phim cov khoom lag luam UV LED xav tau yav tom ntej." Wu Ling tau hais tias.
Raws li tus neeg ua tus saib xyuas kev lag luam koom ua ke, Wu Ling tau hais txog tias kev sib koom siab thiab kev koom tes ntawm cov dej ntws sab hauv thiab hauv qab kev lag luam tuaj yeem ua" ntawm sib sib zog nqus ultraviolet LED loj. Ntxiv rau kev txhim kho cov txheej txheem thev naus laus zis, yav tom ntej, peb tseem yuav txuas ntxiv" kev lag luam, tshawb fawb, thiab tshawb fawb" kev sib koom tes ntawm cov thev naus laus zis tshawb nrhiav kev sib txawv hauv ntau qhov txuas ntawm kev lag luam saw, los ntawm qhov chaw sib sib zog nqus UV LED kev lag luam, los ua cov txheej txheem tawg los ntawm txheej, thiab txuas ntxiv txhim kho cov khoom ua tau zoo thiab kev ntseeg tau maj mam ua tau raws li cov kev xav tau ntawm ntau cov ntawv thov thiab daws cov teeb meem thev naus laus zis. ntawm kev tsim kho tshuab.
