UV LEDs, los yog ultraviolet lub teeb-emitting diodes, tau dhau los ua neeg nyiam nyob rau hauv ntau yam kev siv, xws li kev tu qhov chaw hauv tsev mus rau kev kho cov nplaum hauv cov chaw lag luam. Cov ntsiab lus ntawm seb nws puas muaj kev nyab xeeb rau ntsiaUV LEDsyog ib qho uas nquag nug. Peb yuav tsum coj mus rau hauv tus account ntau yam thiaj li yuav muab cov lus teb meej rau cov ncauj lus no, xws li cov qauv sib txawv ntawm UV hluav taws xob, qhov muaj peev xwm ntawm kev raug mob, thiab kev ceev faj txog kev nyab xeeb.
Hom hluav taws xob UV
Feem ntau, muaj peb hom UV hluav taws xob: UVA, UVB, thiab UVC. Ntawm peb, UVA yog qhov muaj zog tshaj plaws thiab muaj qhov ntev tshaj plaws wavelength (315-400 nm). Cov ntawv thov xws li lub txaj tanning thiab qee qhov tshwj xeeb - teeb pom kev zoo siv nws. UVB muaj zog dua thiab muaj luv luv wavelength (280-315 nm). Nws yog thawj hom ntawm UV hluav taws xob uas ua rau tshav kub hnyiab thiab pab hauv lub cev synthesis ntawm vitamin D, tab sis ntev ntev tuaj yeem ua rau tawv nqaij puas thiab txawm tias mob qog noj ntshav. UVC yog lub zog tshaj plaws thiab muaj qhov luv tshaj wavelength (100-280 nm). Lub ntiaj teb txheej txheej ozone absorbs feem ntau ntawm UVC hluav taws xob los ntawm lub hnub, tab sis cov khoom siv hluav taws xob UVC, xws li qee yam UV LEDs, tuaj yeem ua rau muaj kev phom sij heev.
Tejzaum muaj kev phom sij ntawm kev soj ntsuam UV LEDs
Cov kev txhawj xeeb tseem ceeb cuam tshuam nrog UV LEDs yog cov uas cuam tshuam nrog kev ua phem rau ntawm daim tawv nqaij thiab qhov muag. UV rays muaj teeb meem heev rau lub qhov muag. Photokeratitis, uas yog piv rau qhov muag tshav ntuj, tuaj yeem raug coj los ntawm UV LEDs. Mob, liab, kua muag, thiab hnov ntawm cov xuab zeb hauv lub qhov muag yog cov cim qhia ntawm photokeratitis. Cov teebmeem no tuaj yeem nyob ntev txog 48 teev thiab feem ntau pib tshwm ob peb teev tom qab kis tau. Ntev -lub sij hawm, kev puas tsuaj loj dua li cov kab mob cataracts, uas ua rau lub qhov muag tsis pom kev thiab thaum kawg ua rau tsis pom kev, tuaj yeem tshwm sim los ntawm kev rov ua dua lossis cuam tshuam rau UV LEDs.
Saib ntawm UV LEDs tuaj yeem ua rau lub qhov muag puas tsuaj thiab ua rau cov tawv nqaij nyob ib puag ncig lub qhov muag kom muaj hluav taws xob txaus ntshai. Vim nws qhov nyias nyias thiab fragility, daim tawv nqaij nyob ib ncig ntawm lub qhov muag yog tshwj xeeb yog yooj yim rau UV-induced puas. Hauv cheeb tsam periorbital, qhov no tuaj yeem ua rau wrinkles, kev laus thaum ntxov, thiab muaj kev pheej hmoo siab ntawm daim tawv nqaij.
Qhov ntev thiab qhov hnyav ntawm qhov raug kuj cuam tshuam qhov kev pheej hmoo. Siab dua - siv UV LEDs, xws li cov uas pom nyob rau hauv industrial UV- cov txheej txheem kho, muab qhov kev pheej hmoo loj dua sai dua. Ntev - lub sij hawm raug rau txawm tias tsawg heev - siv UV LEDs tuaj yeem ua rau muaj kev puas tsuaj loj.
Cov lus qhia txog kev nyab xeeb thiab kev ntsuas kev nyab xeeb
Ntau qhov kev ntsuas kev nyab xeeb yuav tsum tau ua raws thaum ua haujlwm nrogUV LEDs. Ua ntej thiab qhov tseem ceeb, khaws koj ob lub qhov muag kom deb ntawm UV LEDs. Ib txwm siv cov UV- thaiv cov tsom iav kom zoo thaum siv UV- cov khoom emitting. Lub hom phiaj ntawm cov tsom iav tshwj xeeb no yog los tiv thaiv lub qhov muag los ntawm kev puas tsuaj los ntawm kev thaiv cov kab hluav taws xob UV. Txhawm rau kom tsis txhob muaj qhov cuam tshuam tsis zoo, cov neeg ua haujlwm hauv thaj chaw muaj kev lag luam yuav tsum hnav cov ris tsho tiv thaiv uas tiv thaiv cov tawv nqaij ntawm lawv ob lub qhov muag.
Cov chaw tsim khoom cov lus pom zoo yuav tsum tau ua raws li cov lus pom zoo thaum siv UV LED- cov khoom siv hauv tsev, xws li cov tshuaj tua kab mob UV. Qee cov tshuaj tua kab mob UV yog tsim los siv nrog lub hau kaw, khaws lub teeb UV hauv cov khoom thiab tiv thaiv nws los ntawm kev nthuav tawm tus neeg. Tsis txhob siv lub cuab yeej hauv tsev tam sim ntawd thiab tau txais kev pab los ntawm cov chaw tsim khoom yog tias muaj UV teeb pom kev lossis ua haujlwm tsis zoo.
Tsis tas li ntawd, nws yog ib qho tseem ceeb uas yuav tsum xav txog qhov ib puag ncig uas UV LEDs tau ua haujlwm. Xyuas kom tseeb tias qhov chaw muaj qhov cua txaus, tshwj xeeb tshaj yog nyob rau hauv ib puag ncig kev lag luam uas ntau UV LED- raws li cov khoom siv tuaj yeem ua haujlwm. Los ntawm kev ua qhov no, tag nrho cov nqi ntawm UV hluav taws xob hauv huab cua yog txo.
Hauv kev xaus, tsis muaj kev tiv thaiv tsim nyog,UV LEDstxaus ntshai saib. Kev ceev faj txog kev nyab xeeb yog qhov tsim nyog vim qhov hnyav ntawm qhov ua rau muaj kev hem thawj rau ntawm daim tawv nqaij thiab qhov muag, uas suav nrog ob qho tib si tsis xis nyob tam sim ntawd thiab ntev ntev - kev puas tsuaj. Ua raws li cov lus qhia txog kev nyab xeeb, hnav khaub ncaws tiv thaiv kom raug, thiab siv UV LED- cov khoom siv raws li tau hais tseg yog qhov tseem ceeb los tiv thaiv peb txoj kev noj qab haus huv, txawm nyob hauv chaw lag luam lossis chaw nyob. Peb tuaj yeem txo qhov kev puas tsuaj rau peb lub cev thaum tseem txaus siab rau ntau yam kev siv tau zoo ntawm UV LEDs yog tias peb paub txog kev phom sij thiab ua raws li kev ntsuas tsim nyog.
