Deep-ultraviolet LEDs yog dav siv, suav nrog: tshuaj tua kab mob ntawm cov dej haus, cua, dej haus, thiab ntim tshuaj; tshuaj tua kab mob ntawm cov cuab yeej phais thiab ua raws li kev ua kom tsis muaj menyuam; Nyob rau hauv lub tub yees, nws tua cov kab mob uas muaj sia nyob, thiab ua rau lub neej txee ntawm cov zaub mov. Ntxiv rau cov tshuaj tua kab mob, cov LEDs sib sib zog nqus ultraviolet tuaj yeem ua cov tshuaj tua kab mob catalysis, number case curing, thiab lwm yam.
Nrog rau txoj kev loj hlob ntawm kev tshawb fawb thiab thev naus laus zis, kev sib sib zog nqus-ultraviolet LEDs hloov cov kev txawj ntse thiab cov khoom siv qub thiab muaj kev lag luam dav dav. Peb piv cov sib sib zog nqus-ultraviolet LEDs nrog qee cov khoom nws hloov, thiab nws qhov zoo yog qhov tseem ceeb:
mercury teeb: Hauv kev kho mob thiab zaub mov, cov roj teeb uas muaj mercury tsawg feem ntau yog siv los ua kom tsis muaj menyuam. Txawm li cas los xij, vim tias mercury tsuas yog ua rau ib puag ncig puas tsuaj, cov kws tshawb fawb yeej ib txwm xav pom cov kev hloov hauv ib puag ncig nrog kev ua haujlwm zoo. Sib sib zog nqus ultraviolet yog ib hom ntawm ultraviolet lub teeb nrog ib tug luv luv wavelength, uas muaj ib tug kuj muaj zog hwj chim tua kab mob thiab kab mob. Txawm hais tias tag nrho cov zis hluav taws xob ntawm lub teeb mercury ib txwm muaj loj, qhov teeb pom kev siv hluav taws xob hauv ib cheeb tsam tsis muaj zog, tsuas yog ob peb feem pua ntawm cov 280nm UV LED. Yog li ntawd, qhov sib sib zog nqus-ultraviolet 280-nanometer band LED yog qhov tsim nyog rau kev tua kab mob sai sai ntawm lub sijhawm ze tshaj li cov teeb mercury, thiab cov cuab yeej siv tau tshwj xeeb.
Traditional UV teeb: Vim tias qhov yuav tsum tau ua ntawm nws txoj haujlwm kev ua haujlwm, cov teeb pom kev zoo ib txwm muaj UV loj heev thiab xav tau cov teeb pom kev zoo siab piv nrog LEDs uas tau muab cais ua cov khoom semiconductor. Tsis tas li ntawd, txawm hais tias tag nrho cov tso zis hluav taws xob ntawm lub teeb mercury ib txwm muaj loj, qhov teeb pom kev siv hluav taws xob hauv ib cheeb tsam tsis muaj zog heev, tsuas yog ob peb feem pua ntawm cov 280nm UV LED. Yog li ntawd, qhov sib sib zog nqus-ultraviolet 280-nanometer band LED yog qhov tsim nyog rau kev tua kab mob sai sai ntawm lub sijhawm ze tshaj li cov teeb mercury, thiab cov cuab yeej siv tau tshwj xeeb.
Mercury teeb: Piv nrog mercury teeb ultraviolet lub teeb qhov chaw, sib sib zog nqus ultraviolet LED raws li txhuas gallium nitride (AlGaN) cov ntaub ntawv muaj qhov zoo ntawm kev sib sau ua ke, txuag hluav taws xob, lub neej ntev, kev tiv thaiv ib puag ncig tsis muaj mercury, thiab lwm yam, thiab maj mam nkag mus rau cov tsoos tsoos. daim ntawv thov qeb ntawm mercury teeb.
Niaj hnub no, LED teeb pom kev zoo yog nrov heev, lub teeb xiav puas tau nkag mus rau txhua tus' qhov kev pom ntawm lub zeem muag ib zaug, ua rau ntau cov lus pom hauv kev lag luam. Lub teeb xiav puas loj npaum li cas? Kev kuaj pom pom tam sim no tsis muaj tseeb. Yog li ntawd puas ultraviolet LED ua puas rau tib neeg lub cev? Ib tus neeg sau xov xwm los ntawm New Century LED Network tau kawm hauv Is Taws Nem tias lub zog ntawm qhov sib sib zog nqus ultraviolet 280 nanometer band LEDs yog qhov me me, thiab nws txoj kev ua kom tsis muaj menyuam nyob ntawm qhov tsis tshua muaj teeb pom kev hauv ib cheeb tsam, ntau dua li lub zog siab. Lub illuminance ib chav tsev ntawm LED yog inversely proportional rau lub square ntawm lub caij. Yog li ntawd, sab nraum lub sijhawm ua haujlwm kom tsis muaj menyuam, cov nyhuv ntawm qhov sib sib zog nqus ultraviolet LED ntawm tib neeg cov tawv nqaij yog tsawg. Tsis tas li ntawd, qhov tob-ultraviolet LEDs yog compact, yooj yim rau nkaum thiab npaj, thiab dav dav iav thiab yas tsawg dua 0.1 hli tuab tuaj yeem nqus ultraviolet tob. Ib yam li lub teeb, riam, lub qhov hluav taws xob, thiab lwm yam hauv cov hnub qub, kev nyab xeeb ntawm UV LED cov khoom tuaj yeem ua kom ntseeg tau yog tias lawv siv thiab npaj kom zoo.
Tam sim no, lub hom phiaj tseem ceeb ntawm kev sib sib zog nqus ultraviolet UV-LED yog kev ua kom tsis muaj menyuam thiab tua kab mob, thiab nws daim ntawv thov kev lag luam koom nrog kev ua kom tsis muaj menyuam, zaub mov kom tsis muaj menyuam thiab lwm yam haujlwm. Vim tias nws tau txais lub hauv paus ntsiab lus ntawm kev puas tsuaj rau lub cev, tsis zoo li tshuaj tua kab mob, nws tsis cuam tshuam los ntawm qhov kub thiab txias, concentration, kev ua haujlwm thiab lwm yam. Nws yog non-toxic, non-residual, thiab tsis muaj ntxhiab, tshwj xeeb tshaj yog haum rau huab cua, dej thiab tshuaj tua kab mob saum npoo.
Raws li kev lag luam sab hauv, kev lag luam thoob ntiaj teb rau cov teeb ci ultraviolet mercury yog kwv yees li US $ 800 lab hauv xyoo 2013, thiab qhov ntsuas ntawm cov khoom siv thiab cov tshuab tuaj yeem nthuav tawm 10 zaug, txog li US $ 8 billion. Kev lag luam nplai ntawm ultraviolet LED lub teeb qhov chaw kwv yees mus txog ntau dua US $ 8 nphom vim ua tiav kev hloov pauv thiab nthuav dav ntawm thaj chaw thov tshiab. Raws li kev kwv yees ntawm cov koom haum tso cai txawv teb chaws: UV LED kev lag luam yuav loj hlob ntawm tus nqi txhua xyoo ntawm 30% hauv 5 xyoo tom ntej.
