Vim nws lub neej ntev, kev lag luam hluav taws xob, thiab kev sib txawv, LED panels tau dav siv hauv ntau yam kev siv teeb pom kev zoo. Seb puas los yog tsis LED panels emit ultraviolet (UV) hluav taws xob yog ib qho teeb meem nquag nug. Peb yuav tsum tshuaj xyuas qhov sib txuas ntawm UV emissions thiab LED panels hauv kab lus no.
Kev Taw Qhia rau LED Panels
Lub teeb -emitting diodes, lossis LEDs, yog cov khoom siv hluav taws xob uas tsim lub teeb los ntawm hluav taws xob hluav taws xob. Txhawm rau tsim kom muaj lub teeb pom kev zoo sib xws, ntau qhov sib txawv ntawm LEDs tau muab tso ua ke hauv ib qhoLED vaj huam sib luag. Electroluminescence yog txheej txheem uas lub teeb tawm hauv LEDs. Ib qho LED cov khoom siv semiconductor tso tawm lub zog nyob rau hauv daim ntawv ntawm photons thaum electrons recombine nrog electron qhov thaum muaj hluav taws xob tam sim no ntws hla nws.
Lub teeb wavelengths tsim los ntawm LEDs
LEDs tuaj yeem tsim los tawm ntau lub teeb lub teeb, txhua tus sawv cev rau xim xim. Lub wavelength ntau ntawm pom lub teeb yog li ntawm 380 thiab 780 nanometers (nm). Liab LEDs, piv txwv li, feem ntau emit lub teeb ntawm 620 thiab 750 nm, ntsuab LEDs ntawm 500 thiab 570 nm, thiab xiav LEDs ntawm 450 thiab 495 nm.
Cov khoom ntawm UV Radiation
Lub wavelength ntawm ultraviolet hluav taws xob yog nyob nruab nrab ntawm 10 thiab 400 nm, uas yog luv dua qhov pom lub teeb. Peb subcategories kuj txawv: UVA (315–400 nm), UVB (280–315 nm), thiab UVC (100–280 nm). Lub ntiaj teb txheej ozone absorbs feem ntau ntawm UVC lub zog siab. Thaum UVA tuaj yeem nkag mus tob rau hauv daim tawv nqaij thiab tseem ua rau cov tawv nqaij puas tsuaj, UVB paub tias ua rau tshav kub kub thiab muaj lub luag haujlwm hauv kev laus ntawm daim tawv nqaij thiab kev loj hlob ntawm daim tawv nqaij.
Puas yog UV Rays tawm los ntawm LED Panels?
Feem ntau hais lus, hwm LED vaj huam sib luag yog tsim los tawm me ntsis UV teeb li sai tau. Qhov no feem ntau yog vim qhov tseeb tias LEDs tau tsim thiab ua haujlwm los tsim lub teeb pom kev. Feem ntau ntawm lub zog yog hloov mus rau hauv pom spectrum photons los ntawm engineering ntawm feem ntau ntawm cov neeg siv khoom thiab kev lag luam - qib LED panels.
Txawm li cas los xij, hauv qee qhov xwm txheej, LED vaj huam sib luag tuaj yeem suav nrog cov kab hluav taws xob ntau ntawm UV hluav taws xob:
Kev hloov pauv Phosphor tsis tiav: Txhawm rau tsim lub teeb dawb lossis ntau lub teeb pom kev, LEDs nquag siv phosphor los hloov lub teeb xiav rau hauv lwm cov xim. Ib feem me me ntawm lub zog yuav qee zaus raug tso tawm raws li UV hluav taws xob yog tias cov txheej txheem hloov pauv phosphor tsis zoo 100%. Txawm li cas los xij, qhov ntau yog qhov tsawg kawg nkaus, feem ntau nyob deb ntawm qhov chaw pib uas tuaj yeem ua rau muaj kev phom sij heev rau ib tus neeg noj qab haus huv.
LEDs uas tsis zoo lossis tsis zoo: Tsawg-zooLED vaj huam sib luagtuaj yeem siv cov khoom tsis zoo lossis muaj qhov tsis zoo ntawm kev tsim khoom. Cov khoom siv semiconductor tsis tsim nyog lossis teeb meem nrog phosphor txheej thiab encapsulation tuaj yeem ua rau cov teeb meem LEDs no yuav tsim tau qee lub teeb UV.
Yam ntxwv ntawm Kev Nyab Xeeb thiab Kev Noj Qab Haus Huv
Txawm hais tias cov vaj huam sib luag LED qee zaus tso tawm lub teeb ultraviolet, cov nyiaj feem ntau yog tsawg heev uas lawv tsis ua rau tib neeg noj qab haus huv. Thaum nws los txog rau UV raug, LED vaj huam sib luag muaj kev nyab xeeb dua li cov teeb pom kev zoo ib yam li cov qij fluorescent, uas tuaj yeem tsim qhov sib piv ntau dua UV vim yog cov txheej txheem mercury vapor tawm.
Cov koom haum tswj hwm tau tso cov kev txwv ntau npaum li cas UV hluav taws xob teeb pom kev zoo tuaj yeem tso tawm kom thiaj li lav kev nyab xeeb rau pej xeem. Txhawm rau lav tias lawv cov khoom muaj kev nyab xeeb rau cov neeg siv khoom siv, LED vaj huam sib luag cov tuam txhab yuav tsum ua raws li cov qauv no.
Kev xav kawg
Hauv kev xaus, txawm hais tias ib qho me me ntawm UV hluav taws xob tuaj yeem raug tso tawm los ntawm LED vaj huam sib luag, tshwj xeeb tshaj yog nyob rau hauv cov xwm txheej uas cuam tshuam nrog kev tsim khoom lossis hloov phosphor tsis txaus, cov nyiaj feem ntau tsis tseem ceeb. Txhawm rau txo qhov kev tso tawm UV ua tau, siab - zoo LED vaj huam sib luag yog tsim los hloov yuav luag txhua lub zog hluav taws xob rau hauv lub teeb pom kev. Thaum nws los txog rau UV raug,LED vaj huam sib luagyog qhov kev xaiv muaj kev nyab xeeb dua li ntau lwm qhov chaw teeb pom kev zoo los ntawm kev noj qab haus huv thiab kev nyab xeeb. Peb yuav cia siab tias cov neeg tsim khoom ntawm LED vaj huam sib luag yuav ua kom zoo dua lawv cov qauv tsim raws li kev siv tshuab tsim, txo qis txawm tias qhov tsawg tshaj plaws ntawm UV hluav taws xob uas tuaj yeem tshwm sim tam sim no. Vim li no, LED vaj huam sib luag yog qhov kev cia siab, nyab xeeb, thiab lub zog- kev xaiv zoo rau ntau yam kev siv teeb pom kev zoo yav tom ntej.
