Lub luag hauj lwm ntawm UV liab doog teeb hlaws, ib leeg-band teeb hlaws, 265 ~ 280 teeb hlaws yog cov kab hluav taws xob tua hluav taws. Ntxiv nrog rau cov kab mob bactericidal, lub dual-band teeb hlaws tuaj yeem tshem tawm cov organic dyes, formaldehyde thiab lwm yam kuab paug nyob rau hauv qhov kev txiav txim ntawm photocatalysts.
UVC LED germicidal teeb yog tam sim no kub kub tshuaj tua kab mob ultraviolet teeb. Vim UV LED txias teeb qhov chaw, UVC LED kab mob teeb tsis tas yuav tsum tau preheated zoo li cov tsoos low-pressure mercury ultraviolet disinfection teeb, thiab UVC LED germicidal teeb tsis tsim ozone los yog tsw tsw. Tsis tas li ntawd, UVC LEDs kuj muaj cov yam ntxwv ntawm kev ua haujlwm siab luminous, tsawg zog noj, ib lub wavelength, thiab ntev lifespan, uas yog lub neej yav tom ntej ntawm kev sib sib zog nqus ultraviolet sterilization. Txawm hais tias UVC LED muaj qhov zoo tshaj plaws, tseem muaj qee qhov tsis paub tseeb tam sim no, xws li kev ua kom tsis muaj menyuam, teeb meem kub dissipation thiab nqi teeb meem.
Kev xaiv ntawm ultraviolet sterilization band muaj qhov cuam tshuam ncaj qha rau kev ua kom tsis muaj menyuam. Ultraviolet rays nrog lub wavelength ntawm 254nm muaj lub zog ua kom puas tsuaj loj tshaj plaws ntawm cov qauv molecular ntawm DNA thiab RNA hauv cov hlwb, yog li theoretically cov nyhuv sterilization zoo dua, tab sis kev lag luam tseem muaj teeb meem hauv kev lag luam ntawm UVC LEDs. , UVC LED ntau lawm nyob rau hauv 254nm band tseem nyuaj rau kev tawg. Qhov no yog vim qhov luv luv, qhov nyuaj dua, qhov qis dua, thiab tus nqi ntau dua. Ntau tus neeg tsim chips tau tig mus rau UVC LEDs hauv 265nm band kom ua kom tsis muaj menyuam los ntawm kev ua kom muaj zog. Qee cov UVC LED cov kab mob tua kab mob txawm xaiv 270 ~ 280nm band. Ib lub nti kuj tau los ntawm thawj 1mW mus rau 10mW, thiab tom qab ntawd mus rau 50mW, 100mW, thiab tau ntsib cov txheej txheem loj hlob los ntawm qis zog mus rau nruab nrab lub zog, thiab tom qab ntawd mus rau lub zog siab.
Ntxiv nrog rau kev cia siab rau lub teeb pom kev zoo ntawm cov nti, qhov nce ntawm lub zog ntawm ib qho UVC LED kuj yuav tsum tau ua tiav los ntawm kev nce qhov loj ntawm cov nti. Txawm li cas los xij, qhov loj dua qhov chip loj, qhov yooj yim dua. Lub zog ntau dua UVC LED nti yog qhov nyuaj rau txiav, tus nqi tawm los tsawg, thiab nws kim dua. Yog li ntawd, kev lag luam feem ntau txais kev koom ua ke ntawm ntau lub zog qis zog kom ua tiav lub zog siab.
Kev nce lub teeb xa hluav taws xob kuj yog ib qho tseem ceeb hauv kev txhim kho kom tsis muaj menyuam. Ntawm qhov chaw ntawm kev ua kom ntseeg tau, UVC LED cov tuam txhab siv cov khoom ntim nrog lub teeb xa hluav taws xob ntau dua li qhov ua tau. Nyob rau theem ntawm sterilization module tsim, lub ntsiab kev txiav txim siab yog kom optimize lub reflection ntawm ultraviolet lub teeb nyob rau hauv lub module kom txo tau optical zog poob.
