Cov teeb meem technical ntawm LED vaj teeb
Dec 05, 2021
Nrog lub tshuab hluav taws xob ntawm LED teeb pom kev lag luam rau hauv kev ua lag luam, kev txhim kho ntawm LED txoj kev teeb tau maj mam ua kom pom tseeb. Qhov sib txawv ntawm ntau lub tuam txhab rushing mus rau LED txoj kev teeb lag luam yog tawm ntawm kev tswj. Txawm hais tias kev lag luam LED tau tsim sai heev nyob rau xyoo tas los no, tseem tsis muaj cov qauv kev cai lij choj, uas ua rau muaj kev tsis sib xws hauv tag nrho kev lag luam, uas yog qhov tsis zoo rau kev txhawb nqa loj. Raws li rau LED txoj kev teeb nrog cov teeb meem kev nyuaj siab, cov teeb meem tshwm sim los ntawm qhov tsis muaj cov qauv kev qhia tshwj xeeb yog pom tseeb. Ntau lub tuam txhab LED thiab cov neeg koom ua ke nrog cov thev naus laus zis zoo tsis paub yuav tsim lub vaj teeb pom kev zoo li cas, thiab daim ntawv thov lub tuam tsev tuaj yeem' tsis qhia cov kev cai tshwj xeeb. Piv txwv li, ntau manufacturers tau tsim ib tug" hollow-out" lampshade thiaj li yuav daws tau qhov teeb meem ntawm LED tshav kub dissipation. Tab sis rau lub tshav puam teeb, hom zoo li no muaj kev ua haujlwm tsis zoo ntawm" tiv thaiv cua thiab nag" thiab tsis haum rau cov teeb ci LED teeb.
Txawm hais tias nyob rau hauv kev txhawb nqa muaj zog los ntawm tsoomfwv, LED lub teeb vaj tsev teeb kev lag luam tab tom txhim kho sai, nws tsis tuaj yeem tsis quav ntsej tias nws tseem tab tom ntsib teeb meem loj heev txhawm rau kom tau txais txoj kev loj hlob mus sij hawm ntev ntawm LED vaj huam sib luag teeb lag luam. Ntxiv nrog rau cov nqi siab, cov teeb meem tseem ceeb ntawm LED vaj teeb cov khoom lag luam muaj xws li: lub teeb ci, cua sov dissipation thiab lub zog hluav taws xob.
Los ntawm qhov kev xav ntawm lub teeb ci, ntawm ib sab, nws yog ib qho tsim nyog los txhim kho lub teeb pom kev zoo ntawm LEDs, thiab ntawm qhov tod tes, nws yog los txhim kho kev teeb tsa ntawm lub teeb. Nyob rau hauv ib qho loj ntawm LED vaj teeb khoom ntawm lub khw, LED teeb qhov chaw yog teem rau hauv ib lub lattice qauv. Qhov zoo tshaj plaws ntawm txoj kev no yog tias nws muaj txiaj ntsig los daws qhov teeb meem kub dissipation. Txawm li cas los xij, vim qhov tsis txaus sab irradiation ncua deb ntawm cov qauv no, lub teeb qhov chaw faib khoom yog luv luv. Nws tsis tuaj yeem paub txog lub teeb pom kev zoo ntawm lub khob tsom iav, thiab nws yuav tsum siv lub lens thib ob kom ua tiav lub teeb pom kev ywj pheej. Qhov no yuav tsum xaiv cov khoom siv ntau dua rau lub lens thib ob. Muaj qee qhov teeb meem nrog lub lens thib ob ntawm cov khoom sib txawv, uas cuam tshuam rau cov khoom' s kev ua tau zoo. nyhuv. Yog tias nws tsis ua haujlwm zoo, kev siv cov lo ntsiab muag tseem yuav cuam tshuam rau lub teeb pom kev zoo thiab qhov pom tseeb ntawm txoj kev.
Txhawm rau txhim kho cov teeb meem saum toj no, qee lub tuam txhab LED vaj teeb pom kev lag luam tau qhia txog cov teeb pom kev zoo uas siv cov qauv sib xyaw. Daim ntawv ntim lub teeb no txo qis qhov tsis muaj qhov ci ntawm ib lossis ob peb yam khoom vim yog kev teeb tsa ntawm lub teeb ci thaum lub rooj tsav xwm Circuit Court yog soldered thiab cov khoom tiav ua haujlwm. . Tsis tas li ntawd, txij li lub khob tsom iav tuaj yeem siv los ua kom muaj kev sib koom ua ke ntawm lub teeb, qhov tsis zoo tshwm sim los ntawm kev siv cov lo ntsiab muag thib ob kuj tuaj yeem zam tau. Tab sis nws yog undeniable tias lub teeb qhov chaw uas siv hom pob no yuav ntsib cov teeb meem kub dissipation ntau dua. Los ntawm qhov kev xav ntawm cov khoom siv hluav taws xob, sib txawv ntawm cov khoom siv teeb pom kev zoo uas tuaj yeem txuas ncaj qha rau AC mains, LEDs yog cov khoom siv hluav taws xob tsawg thiab yuav tsum tau tsav tam sim no, uas yuav tsum tau kho dua tshiab ntawm lub zog hluav taws xob ntawm LED vaj teeb. Tus nqi ntawm cov khoom siv hluav taws xob LED suav txog li 10% -20% ntawm tag nrho cov khoom lag luam tus nqi, thiab qhov tsis ua haujlwm ntawm lub zog hluav taws xob yuav cuam tshuam rau cov khoom lag luam mus rau qhov loj.
Daim ntawv thov nce qib kuj yog vim li cas cuam tshuam txoj kev loj hlob ntawm LED vaj teeb. Txij li thaum tsis muaj tus qauv tsim rau LED vaj teeb, lub ntsiab tsis xws li xim kub, xim rendering thiab glare tseem tsis tau txiav txim siab, thiab LED vaj teeb tsis tuaj yeem txhawb nqa tag nrho. Qhov thib ob, tus nqi siab ntawm LED vaj teeb kuj coj teeb meem loj rau kev nce qib thiab daim ntawv thov ntawm LED txoj kev teeb. Tsis tas li ntawd, cov qauv teeb pom kev zoo rau LED vaj teeb thiab txoj kev pavement test method standard for use LED garden lights tseem tsis tau tsim. Nyob rau theem no, kev txhim kho ntawm LED txoj kev teeb pom kev lag luam feem ntau yog nyob ntawm tsoomfwv' kev txhawb nqa muaj zog.
