YuavT12 LEDs haum T12 fluorescent fixtures uas twb muaj lawmmuab lawv txoj kab uas hla loj dua (38mm vs. T8's 25.4mm)? Lawv puas xav tau cov neeg tuav tombstone tshiab?
Kev hloov pauv los ntawm T12 fluorescent tubes rau T12 LED hloov cov lus nug tseem ceeb txog kev sib raug zoo nrog cov khoom siv uas twb muaj lawm, tshwj xeeb tshaj yog hais txog lawv txoj kab uas hla loj dua thiab xav tau cov neeg tuav tombstone tshiab. Cov kev txiav txim siab no yog qhov tseem ceeb rau cov neeg siv nrhiav kev txhim kho cov teeb pom kev zoo yam tsis muaj nqi ntau dhau lossis kev hloov kho ntau.
Ua ntej, lubtxoj kab uas hlaQhov sib txawv ntawm T12 LEDs thiab lawv cov fluorescent counterparts yog qhov tseem ceeb. T12 fluorescent leeg muaj ib txoj kab uas hla ntawm 38 hli, thiab T12 LEDs yog tsim los kom haum rau qhov loj me, kom ntseeg tau tias lawv haum nyob rau hauv lub cev kev txwv ntawm T12 fixtures uas twb muaj lawm. Tsis zoo li T8 LEDs, uas yuav tsum tau hloov mus rau qhov me me 25.4mm txoj kab uas hla, T12 LEDs tuav tib qhov loj me raws li lawv cov thawj coj. Qhov no txhais tau hais tias lawv feem ntau haum rau hauv lub tsev fixture yam tsis muaj teeb meem ntsig txog kev tshem tawm. Lub thav duab ntawm T12 fixtures, nrog rau qhov chaw sab hauv thiab mounting brackets, yog engineered kom haum 38mm hlab, yog li lub cev haum ntawm T12 LEDs feem ntau seamless. Txawm li cas los xij, muaj qhov tshwj xeeb tsis tshua muaj: kev sib tw nrog cov kab sib txawv hauv qhov nqaim lossis kev hloov kho kev cai yuav ua rau muaj teeb meem, tab sis cov xwm txheej zoo li no tsis tshua muaj tshwm sim hauv kev lag luam lossis kev teeb tsa hauv tsev.
Tom ntej no, lo lus nug ntawmtombstone tuav (socket fixtures)yog ntau nuanced. Ib txwm siv T12 fluorescent raj siv G13 puag, uas tseem ua haujlwm los ntawm T12 LEDs feem ntau. Qhov kev sib koom tsim qauv qhia tau hais tias cov neeg tuav tombstone uas twb muaj lawm yuav tsum sib haum, vim lawv tau tsim los tuav cov pins ntawm G13-raws li cov raj. Txawm li cas los xij, kev ua haujlwm ntawm cov tuav no nyob ntawm lawv tus mob thiab tsim. Cov qub tombstone tuav, tshwj xeeb tshaj yog cov uas siv nrog cov sib nqus ballasts, tej zaum yuav muaj kev sib cuag los yog lub caij nplooj ntoos hlav mechanisms uas tawm tsam kom muaj kev ruaj ntseg nrog T12 LEDs. LEDs xav tau kev sib txuas hluav taws xob zoo ib yam kom ua haujlwm tau zoo, thiab kev sib cuag xoob tuaj yeem ua rau flickering, txo qis kev ua haujlwm, lossis txawm tias muaj kev puas tsuaj rau LED tsav tsheb.
Lwm qhov kev txiav txim siab yogseb cov neeg tuav lub qhov ntxa yog shunted los yog tsis -shunted. Traditional T12 fluorescent systems feem ntau siv tsis yog -shunted tombstone tuav, uas cais cov hluav taws xob txoj hauv kev kom haum raws li ballast txoj cai tam sim no. T12 LEDs, tshwj xeeb tshaj yog cov uas tsim los rau ballast-bypass installation, tej zaum yuav xav tau shunted tombstone tuav, uas txuas ob tus pins ntawm txhua qhov kawg kom tso cai ncaj qha mus rau lub mains. Qhov no yog vim ballast-bypass T12 LEDs ua haujlwm ntawm qhov hluav taws xob ncaj qha (DC) lossis qis-voltage alternating tam sim no (AC) yam tsis tas yuav tsum muaj lub ballast, ua kom muaj hluav taws xob txuas ntxiv tsim nyog. Nyob rau hauv cov xwm txheej zoo li no, cov uas twb muaj lawm uas tsis yog -shunted tuav yuav tsum tau hloov nrog shunted sawv daws yuav xyuas kom meej functionality thiab kev nyab xeeb.
Ntxiv mus, qee qhov T12 LEDs tau tsim los ua kom sib haum nrog cov ballasts uas twb muaj lawm, zoo ib yam li cov qauv T8 LED. Cov ballast no-tshaj T12 LEDs tuaj yeem ua haujlwm nrog cov uas tsis yog-shunted tombstone tuav, raws li lawv tso siab rau lub ballast tswj tam sim no, ua raws li kev ua haujlwm ntawm cov raj fluorescent. Txawm li cas los xij, kev sib raug zoo nrog cov hlau nplaum sib nqus (feem ntau hauv cov laus T12 tshuab) yog txwv. Sib nqus ballasts ua kom muaj qhov siab pib qhov hluav taws xob uas tuaj yeem ua rau cov khoom siv hluav taws xob puas, ua rau ua tsis tiav ntxov. Cov hluav taws xob ballasts, thaum muaj txiaj ntsig zoo dua, tseem yuav tsum muaj kev pov thawj tawm tsam LED cov chaw tsim khoom tshwj xeeb kom ntseeg tau tias muaj qhov hluav taws xob thiab qhov sib txuam tam sim no.
Lub hnub nyoog thiab qhov xwm txheej ntawm cov neeg tuav tombstone uas twb muaj lawm kuj ua lub luag haujlwm. Sij hawm dhau mus, cov hlau sib txuas hauv cov neeg tuav tombstone tuaj yeem corrode los yog poob nro, tshwj xeeb tshaj yog nyob rau hauv ib puag ncig uas muaj av noo los yog hmoov av. Txawm hais tias lub cev haum yog qhov tseeb, kev sib cuag hluav taws xob tsis zoo tuaj yeem cuam tshuam qhov kev ua tau zoo ntawm T12 LEDs. Nyob rau hauv cov xwm txheej zoo li no, hloov lub tombstone tuav-txawm tias lawv yog technically haum- tuaj yeem txhim kho kev ntseeg tau thiab txuas ntxiv lub neej ntawm cov raj LED. Cov neeg tsim khoom feem ntau pom zoo kom kuaj xyuas thiab, yog tias tsim nyog, hloov tombstone tuav thaum lub sijhawm hloov kho rau T12 LEDs, tshwj xeeb tshaj yog nyob rau hauv cov khoom siv uas tau siv rau kaum xyoo lossis ntau dua.
Hauv cov ntsiab lus, T12 LEDs yog tsim los kom haum rau lub cev qhov ntev ntawm T12 fluorescent fixtures uas twb muaj lawm, ua tsaug rau lawv txoj kab uas hla 38mm. Txawm li cas los xij, qhov xav tau rau cov neeg tuav hauv qhov ntxa tshiab yog nyob ntawm yam xws li hom tuav (shunted vs. non-shunted), LED tus tsim (ballast- sib xws vs. ballast-bypass), thiab cov xwm txheej ntawm cov khoom uas twb muaj lawm. Ballast-bypass T12 LEDs feem ntau xav tau shunted tombstone tuav, thaum ballast{12}}cov qauv sib xws tuaj yeem ua haujlwm nrog tsis yog{13}}shunted sawv daws yuav, yog tias lub ballast sib haum. Rau kev ua tau zoo thiab kev nyab xeeb, cov neeg siv yuav tsum xyuas cov chaw tsim khoom cov lus qhia, tshuaj xyuas tombstone tuav uas twb muaj lawm rau hnav, thiab hloov lawv yog tias tsim nyog. Los ntawm kev hais txog cov xwm txheej no, kev hloov pauv mus rau T12 LEDs tuaj yeem yog ob qho tib si tus nqi - siv tau zoo thiab ua haujlwm zoo, siv cov khoom siv uas twb muaj lawm thaum tau txais txiaj ntsig ntawm LED thev naus laus zis.
