Qhia koj yuav ua li cas yuav LED fluorescent teeb fais fab mov
LED fluorescent teeb fais fab mov yog qhov tseem ceeb tshaj plaws ntawm LED fluorescent teeb. Yog tias LED fluorescent teeb tsis raug xaiv kom raug, LED fluorescent teeb yuav tsis muaj peev xwm ua kom nws ua tau zoo lossis tseem siv tau ib txwm. Hauv cov txheej txheem ntawm kev koom tes nrog cov neeg siv khoom, peb pom qee qhov kev nkag siab yuam kev. Nov yog qee qhov rau cov neeg siv khoom' siv thaum xaiv.
1. Yuav tsum yog tam sim no tsis tu ncua: Cov yam ntxwv ntawm semiconductors txiav txim siab tias nws cuam tshuam ntau heev. Lub sijhawm ua haujlwm ntev tshaj li qhov ntsuas tam sim no yuav ua rau lub neej ua haujlwm ntawm LED luv luv. Lub LED tsis tu ncua tam sim no yog los xyuas kom meej tias nws cov kev khiav hauj lwm tam sim no tseem tsis hloov thaum yam xws li kub thiab voltage hloov.
2. Kev sib txuam ntawm LED fluorescent teeb lub zog thiab lub teeb lub rooj tsavxwm: xaiv qhov zoo tshaj plaws series thiab kev sib txuas sib txuas, qhov voltage thiab tam sim no siv rau txhua lub LED yog tib yam, tab sis cov nyhuv ntawm lub hwj huam mov tuaj yeem ua tau zoo tshaj plaws. Txoj kev zoo tshaj plaws yog kev sib txuas lus nrog cov chaw tsim khoom siv hluav taws xob ua ntej, thiab txiav nws.
3. Kev ua haujlwm tam sim no ntawm LED: qhov ntsuas kev ua haujlwm tam sim no ntawm cov LED dav dav yog 20 mA, thiab qee lub chaw tsim khoom siv nws thaum pib, thiab tus qauv tsim yog 20 mA. Qhov tseeb, kev ua haujlwm tam sim no nyob rau hauv qhov tam sim no yog qhov hnyav heev. Tom qab ntau qhov kev sib piv, tus qauv tsim yog 16-18 mA yog qhov zoo tagnrho. Tag nrho tam sim no ntawm N parallel txuas=17N;
4. LED ua hauj lwm voltage: qhov pom zoo ua hauj lwm voltage ntawm dav LED yog 3.0-3.5V. Tom qab kev sim, feem ntau ntawm lawv ua haujlwm ntawm 3.125V, yog li cov qauv kev suav ntawm 3.125V yog qhov tsim nyog dua. Tag nrho qhov voltage ntawm M teeb hlaws=3.125M
5. Kev sib txuas thiab kev sib txuas ntawm LED lub teeb boards thiab dav voltage: Tam sim no lub zog hluav taws xob feem ntau yog ib qho uas tsis yog-kauj ruam-down fais fab mov. Thaum qhov hluav taws xob dav dav, qhov tso zis hluav taws xob yuav tsum tsis pub tshaj 72V, thiab qhov hluav taws xob input voltage tuaj yeem ncav cuag 85-265V. Tus naj npawb tsis tshaj 23 kab. Tsis txhob txuas ntau dhau mus ua ke, txwv tsis pub ua haujlwm tam sim no yuav loj dhau thiab qhov kub yuav hnyav. Nws raug pom zoo kom ua 6-parallel / 8-parallel / 12-parallel. Tag nrho cov tam sim no yuav tsum tsis pub tshaj 240 mA.
6. Kev sib raug zoo ntawm kev sib txuas ntawm kev sib txuas ntawm LEDs thiab dav voltage; muaj peb kis ntawm lub hwj chim mov PFC nyob rau hauv kev ua lag luam: ib tug yog tsis muaj PFC tshwj xeeb hwj chim, thiab nws PFC feem ntau yog nyob ib ncig ntawm 0.65; lwm yam yog nrog passive PFC lub zog, thiab lub teeb lub rooj tsavxwm yog nees-powered. Kev npaj tau zoo, PFC feem ntau nyob ib puag ncig 0.92; Lwm hom yog tsim nrog active 7527/6561, thiab PFC tuaj yeem ncav cuag 0.99, tab sis tus nqi ntawm cov tshuaj no yog ob zaug kim dua li cov tshuaj thib ob. Yog li cov txheej txheem thib ob yog ntau dua.
7. Qhov tseeb tam sim no: qhov tseeb tam sim no ntawm qee cov khoom siv hluav taws xob hauv kev lag luam yog qhov tsis zoo, zoo li qhov yuam kev nrov ntawm kev ua lag luam mus txog ± 8% lossis ± 10%, qhov tsis tu ncua tam sim no yuam kev loj heev. Qhov xav tau yog nyob rau hauv ± 3%. Raws li qhov yuam kev ntawm 3%, 6 nyob rau hauv parallel, qhov yuam kev ntawm txhua tus yog hais txog ± 0.5%, yog tias nws yog 12 nyob rau hauv parallel, qhov yuam kev ntawm txhua qhov yog ± 0.25%, qhov tseeb yog txaus.
8. Kev rho tawm / tsis nyob ib leeg: kev cais tsis raug nqi. Feem ntau, kev sib cais yog qhov tseem ceeb dua, thiab qhov ntim tuaj yeem ua kom me me, nrog qhov siab tsawg kawg nkaus ntawm 8 hli. Qhov tseeb, kev ntsuas kev nyab xeeb tsis nyob ib leeg yog nyob rau hauv qhov chaw. Muaj teeb meem.
9. Kev ua haujlwm ntawm lub zog thiab lub zog ua haujlwm: Lub zog ua haujlwm yog qhov piv ntawm lub zog ua haujlwm rau tag nrho lub zog (￠). Yog tias nws tau teeb tsa hauv lub teeb lub raj, nws yuav tsim qhov kub thiab txias heev, ntxiv rau lub teeb pom kev zoo ntawm peb lub LED. Thaum tshav kub kub ua kom kub siab dua. Kev ua tau zoo yog qhov tseem ceeb tshaj plaws uas txiav txim siab lub neej ntawm cov khoom siv hluav taws xob. Kev ua haujlwm tsis tuaj yeem qis dhau, txwv tsis pub cov cua sov uas siv rau ntawm lub zog hluav taws xob loj dhau. Feem ntau saum 0.8-0.9 yog qhov zoo.
10. Loj: Qhov siab yog qhov tseem ceeb. Feem ntau, qhov loj ntawm T6 raj / T8 xav kom qhov siab yuav tsum tsis txhob siab dhau ≤ 9 hli. Qhov siab ntawm T10 raj yog tsawg dua los yog sib npaug li 15 hli. 11. Daim ntawv pov thawj CE: LED fluorescent teeb tam sim no siv rau kev xa tawm, thiab cov teb chaws txawv teb chaws feem ntau xav tau ntawv pov thawj CE. CE muaj ob ntu, ib qho yog cov lus qhia qis-voltage, rwb thaiv tsev thiab high-voltage kuj; lwm qhov yog cov lus qhia electromagnetic compatibility, electromagnetic cuam tshuam thiab tiv thaiv kev cuam tshuam.
