Cov tiam tam sim no tsis tuaj yeem them taus tsis quav ntsej txog qhov teeb meem tshwm sim los ntawm ultraviolet (UV) hluav taws xob, txawm tias cov tiam dhau los. Hauv txhua qhov chaw tshav ntuj, tshuaj pleev thaiv hnub, looj tsom iav dub, thiab txawm tias cov tshuaj pleev ib ce yog qhov tseem ceeb. Ntau tus neeg yuav tsis paub txog cov teeb meem nrog lub teeb ci thiab UV hluav taws xob los ntawm LEDs, txawm li cas los xij.
Piv nrog rau lawv cov hlau halide thiab high-pressure sodium predecessors, LED qhov muag teev yog tam sim no pheej yig dua, kev lag luam, thiab lub zog txuag ua tsaug rau kev nce qib hauv LED technology. Txawm li cas los xij, cov teeb ci LED puas tawm lub teeb ultraviolet? Peb cov kws tshaj lij yuav sib tham yog tias LED teeb qhov muag teeb muaj teeb meem rau koj txoj kev noj qab haus huv thiab seb lawv cuam tshuam li cas rau UV hluav taws xob hauv phau ntawv qhia no.
Nkag siab txog Cov Ntsiab Cai ntawmUV-Rated Qhov muag teev
Kev txhawj xeeb txog seb cov teeb ci LED tsim hluav taws xob UV puas tshwm sim thaum nws los txog rau lub teeb pom kev zoo. Ib hom hluav taws xob hluav taws xob uas tsis pom ntawm tib neeg lub qhov muag, UV hluav taws xob, tseem hu ua lub teeb ultraviolet, tau lees paub tias muaj peev xwm ua rau mob qog noj ntshav thiab lwm yam teeb meem kev noj qab haus huv. Txawm li cas los xij, muaj qhov sib txawv tseem ceeb ntawm UV hluav taws xob yam ntxwv ntawm ntau hom teeb pom kev zoo, suav nrog fluorescent thiab LED teeb.
LED teeb nrog UV
Lub teeb-emitting diodes, lossis LED teeb, paub zoo rau lawv lub neej ntev thiab kev lag luam hluav taws xob. Nyob rau hauv sib piv rau tej yam compact fluorescent teeb (CFL qhov muag teev) thiab cov pa incandescent qhov muag teev, LED teeb yog tsim los muab lub teeb pom kev zoo yam tsis muaj UV hluav taws xob raws li ib tug byproduct. Lawv yog li kev xaiv muaj kev nyab xeeb dua rau kev nthuav dav hauv tsev thiab chaw ua haujlwm. Tshwj tsis yog tsim tshwj xeeb los ua li ntawd, xws li cov teeb pom kev zoo uas muaj UV rays siv hauv qee cov ntawv tshwj xeeb xws li teeb pom kev dub lossis teeb pom kev loj hlob, cov thev naus laus zis tom qab LEDs ua rau lawv tsim lub teeb ntawm electroluminescence, uas feem ntau tsis suav nrog UV hluav taws xob.
Fluorescent teeb nrog UV
Yog li, puas UV rays los ntawm lub teeb fluorescent? Raws li nws tshwm sim, lawv cov emissions txawv ntawm cov teeb pom kev hauv tsev LED li niaj zaus. Txawm li cas los xij, muaj qee qhov UV hluav taws xob tawm los ntawm cov teeb fluorescent. Qhov no yog vim qhov tseeb tias lub teeb tsim los ntawm cov txheej txheem mercury vapor siv nyob rau hauv cov qij no ib txwm tsim lub teeb ultraviolet, uas tom qab ntawd hloov mus rau hauv cov teeb pom kev zoo los ntawm phosphor txheej hauv lub noob. Txawm hais tias lub teeb fluorescent feem ntau tso tawm UV tsawg heev thiab xav tias yuav muaj kev nyab xeeb thaum siv ib txwm, UV raug tseem yog ib qho kev txhawj xeeb, tshwj xeeb tshaj yog thaum cov qij qub lossis tawg.
Puas yog Kev Noj Qab Haus Huv muaj kev pheej hmoo los ntawm UV Radiation los ntawm Lub Teeb?
Puas muaj kev txhawj xeeb tib yam txog cov teeb pom kev zoo li muaj txog kev tiv thaiv lub hnub UV rays, uas yuav pab tiv thaiv cov tawv nqaij zoo li melanoma thiab lwm yam qog noj ntshav? Yog tias muaj kev phom sij hnyav npaum li lub hnub raug, peb yuav tsis raug teeb pom kev sab hauv ntau npaum li peb tam sim no. Artificial teeb pom kev zoo ua rau muaj kev puas tsuaj ntau dua.
Nws mus yam tsis tau hais tias raug rau qee yam ntawm UV hluav taws xob yuav ua rau muaj kev pheej hmoo ntawm qee yam mob, suav nrog mob qog noj ntshav. Ib qho piv txwv yog UV lub rooj muag khoom pom hauv tanning salons. UV hluav taws xob los ntawm cov qij hauv tsev yuav tsis muaj zog lossis khaus.
Qhov ntau ntawm lub teeb xav tau, txawm li cas los xij, yog ntau dua nyob rau hauv cov ntsiab lus ntawm kev lag luam. Cov chaw tsim khoom hauv tsev no, uas muaj ntau yam ntawm cov ntawv zeb mus rau cov chaw ua zaub mov, xav tau kev tswj hwm nruj, nyob ntawm seb lawv xav siv. Qhov no suav nrog kev siv cov khoom siv dag zog los muab cov teeb pom kev zoo. Nws kuj tseem hais txog qhov muaj qhov tsim nyog ntawm lub teeb kom ua tiav cov haujlwm uas yuav tsum tau ua los ntawm qee qhov haujlwm. Nco ntsoov hloov koj lub teeb LED nrog lub teeb pom kev zoo dua yog tias lawv ci dhau lawm.
Cov teeb meem kev noj qab haus huv txuas rau UV hluav taws xob
UV hluav taws xob txuas nrog ntau yam teeb meem kev noj qab haus huv, suav nrog:
- tawv nqaij puas
- Photokeratitis thiab lwm yam kev puas tsuaj ntawm qhov muag
- Lub zog depletion
- Exacerbating tej yam uas twb muaj lawm xws li lupus erythematosus
Nws tau raug nug ntau npaum li cas UV hluav taws xob cov khoom siv hluav taws xob tso tawm. Txawm hais tias ntau tus niam txiv tuaj yeem hnov cov lus ceeb toom txog lub sijhawm lawv cov menyuam siv sijhawm siv ntsiav tshuaj thiab xov tooj, tsis muaj pov thawj ntau tias UV hluav taws xob los ntawm cov khoom siv no yuav ua rau muaj kev phom sij.
Qhov teeb meem no txawv nrog kev siv hluav taws xob tawm qhov muag teev, xws li kub siab sodium thiab hlau halide teeb. Hauv cov chaw ua haujlwm zoo tib yam, feem ntau ntawm HIDs tso tawm ntau npaum li cas ntawm UV hluav taws xob, yuav tsum tau siv cov ntxaij lim dej tshwj xeeb UV-thaiv kom ua tiav cov cai tswj kev nyab xeeb. Qhov teeb meem kev nyab xeeb nce ntxiv thaum muaj ntau HIDs muaj zog siv los teeb pom kev lag luam loj.
Cov tsom iav kev nyab xeeb yog xav tau los ntawm txoj cai los muab kev tiv thaiv UV nyob rau hauv ntau qhov chaw thaum siv cov teeb pom kev zoo. Faulty lightbulbs tuaj yeem xau thiab ua rau muaj kev puas tsuaj uas tsis tuaj yeem tshawb pom txawm tias thaiv cov cuab yeej lim.
Puas yog UV Rays tawm los ntawm LED Teeb?
Feem ntau LED teeb qhov muag tsis pom UV teeb thaum siv hauv chaw lag luam lossis rau lwm lub hom phiaj. Yav dhau los iterations ntawm LED teeb tsis tuaj yeem tsim lub teeb dawb, uas yog vim li cas lawv tsis tuaj yeem tsim hluav taws xob UV. Tab sis qhov no tau hloov pauv tom qab kev taw qhia ntawm lub teeb dawb LEDs. Brilliant xiav LEDs yog coated nrog phosphor los ua dawb lub teeb LED teeb. Yog li ntawd, tsuas yog cov dawb tuaj yeem dhau los thiab xiav yuav nqus tau.
Brilliant Blues tso tawm me ntsis ntawmUV teeb, txawm tias qhov tseeb tias feem ntau ntawm LED teeb pom kev zoo tsis yog. Tab sis cov phosphor ua rau qhov no me me uas nws yuav luag tsis tsim nyog. Lawv tau siv ntau qhov chaw uas photosensitivity yog qhov teeb meem vim lawv tsis xav tau lub lim. Ib qho ntawm ntau qhov laj thawj LED teeb pom kev zoo yog qhov zoo tshaj qhov siv hluav taws xob tawm qhov muag yog qhov tsis muaj UV rays. Peb cov lus tshaj tawm txog vim li cas HIDs tsis tuaj yeem sib tw nrog LEDs mus rau hauv kev nthuav dav ntxiv txog cov kev sib txawv no.
Yuav ua li cas txiav txim siab qhov kev nyab xeeb ntawm koj lub teeb pom kev lag luam
Ob peb yam tseem ceeb yuav tsum tau ua los lav kev ruaj ntseg ntawm koj lub teeb pom kev lag luam. Ua ntej, nrhiav kev hnav, kev puas tsuaj, lossis kev laus hauv koj qhov muag teev tsis tu ncua. Cov teeb pom kev zoo li qub, xws li lub teeb fluorescent, tuaj yeem ua rau lub sijhawm tsis zoo thiab tawm ntau dua UV hluav taws xob. Thaum nws yog lub sij hawm rau kev hloov, nrhiav pom kev puas tsuaj, qhov tsaus ntuj nti, los yog flickering teeb.
Lwm cov kauj ruam tseem ceeb yog kuaj rau UV emissions. UV lub teeb ntsuas hluav taws xob tuaj yeem pab txheeb xyuas cov hluav taws xob UV hauv koj thaj chaw ua haujlwm, muab cov duab meej rau koj seb qhov teeb pom kev zoo uas koj tam sim no muaj puas txaus ntshai. Nws tuaj yeem yog qhov tseem ceeb los ua tam sim ntawd los tiv thaiv koj cov neeg ua haujlwm los ntawm kev cuam tshuam UV txuas ntxiv yog tias koj qhov kev tshawb pom siab.
Nws tseem yog ib qho tseem ceeb rau kev ntsuam xyuas koj lub teeb pom kev zoo thiab kev ua haujlwm. Ntxiv rau qhov emitting UV rays, cov laus hlau halide thiab fluorescent qij siv zog ntau dua li niaj hnub LED teeb. Ib qho kev hloov tshiab yuav tsim nyog yog tias koj pom cov nqi hluav taws xob ntau dhau lossis muaj teeb meem txij nkawm.
