10 lub tswv yim rau LED fluorescent teeb tsim
Tam sim no, lub lag luam LED fluorescent teeb yog heev nquag, thiab manufacturers feem ntau muab faib ua peb pawg: thawj hom yog lub Hoobkas uas siv los ua LED chips, uas nkag mus rau hauv qab, thiab muaj me ntsis kev paub txog hluav taws xob thiab LED fluorescent teeb lub zog; hom thib ob yog thawj lub teeb pom kev zoo Lub Hoobkas nkag mus rau hauv ib qho chaw tshiab thiab muaj qee yam kev paub txog hluav taws xob; pawg thib peb yog tshiab kiag li rau lub Hoobkas, lawv tau ua lwm yam khoom los yog tshiab ventures ua ntej, thiab muaj ib co kev nkag siab ntawm LED fais fab mov, thiab ib co tsis. 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. Nov yog qee qhov rau koj siv.
1. Vim li cas qhov tam sim no thiaj li tsim nyog:
Cov yam ntxwv ntawm semiconductor txiav txim siab tias nws cuam tshuam ntau heev. Piv txwv li, raws li qhov kub thiab txias hloov, qhov tam sim no ntawm LED yuav nce, thiab qhov nce ntawm qhov hluav taws xob yuav nce qhov tam sim no ntawm LED. 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. Qhov sib txuam ntawm LED fluorescent teeb lub zog thiab lub teeb lub rooj tsavxwm:
Qee cov neeg siv khoom ua ntej tsim lub teeb pom kev zoo thiab tom qab ntawd nrhiav cov khoom siv hluav taws xob. Lawv pom tias nws yog ib qho nyuaj rau kom muaj lub zog tsim nyog. Txawm tias qhov tam sim no loj dhau thiab qhov hluav taws xob tsawg dhau (xws li I> 350mA, V< 40v);="" los="" yog="" qhov="" tam="" sim="" no="" tsawg="" dhau="" thiab="" qhov="" voltage="" siab="" dhau="" (xws="" li="">< 40ma,="" v＞180v),="" qhov="" tshwm="" sim="" yog="" cua="" sov="" loj,="" tsis="" muaj="" zog,="" lossis="" tsis="" txaus="" input="" voltage="" ntau.="" qhov="" tseeb,="" xaiv="" txoj="" kev="" sib="" txuas="" zoo="" tshaj="" plaws="" ntawm="" kev="" sib="" txuas,="" qhov="" hluav="" taws="" xob="" thiab="" tam="" sim="" no="" siv="" rau="" txhua="" lub="" led="" yog="" tib="" yam,="" tab="" sis="" cov="" khoom="" siv="" hluav="" taws="" xob="" tuaj="" yeem="" ua="" haujlwm="" 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="">
3, LED ua haujlwm tam sim no:
Feem ntau, qhov ntsuas ua haujlwm tam sim no ntawm LED yog 20 mA. Qee lub tuam txhab siv nws thaum pib. Tus tsim yog 20 mA. Qhov tseeb, nws kub heev thaum ua haujlwm hauv qab no tam sim no. Tom qab ntau qhov kev sib piv, nws yog qhov zoo tshaj plaws los tsim 17 mA. . Tag nrho tam sim no ntawm N parallel txuas=17N;
4, LED ua haujlwm voltage:
Qhov pom zoo ua haujlwm voltage ntawm cov LEDs dav dav 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. Series-parallel kev twb kev txuas thiab dav voltage ntawm LED teeb lub rooj tsavxwm:
LED fluorescent teeb fais fab mov Yuav ua rau LED fluorescent teeb ua hauj lwm nyob rau hauv ib tug kuj ntau yam ntawm input voltage range AC85-265V, LED series thiab parallel hom ntawm lub teeb vaj huam sib luag yog ib qho tseem ceeb heev. Txij li cov khoom siv hluav taws xob tam sim no feem ntau yog cov khoom siv hluav taws xob tsis raug cais tawm, thaum xav tau qhov hluav taws xob dav dav, qhov tso zis hluav taws xob yuav tsum tsis pub tshaj 72V, thiab cov khoom siv hluav taws xob tuaj yeem ncav cuag 85-265V. Hauv lwm lo lus, tus lej tsis pub dhau 23 txoj hlua. 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. Kuj tseem muaj cov kev daws teeb meem dav dav, uas yog siv L6561/7527 kom nce qhov hluav taws xob mus rau 400V ua ntej, thiab tom qab ntawd nqis, uas yog sib npaug rau ob lub zog hloov hluav taws xob, thiab tus nqi yog ob zaug kim. Cov tshuaj no tsis raug nqi thiab tsis muaj kev lag luam.
Kev lees paub: Cov kab lus no tsuas yog sawv cev rau tus sau' tus kheej kev xav, thiab tsis muaj dab tsi cuam tshuam nrog OFweek Semiconductor Lighting Network. Lub originality thiab cov ntawv nyeem thiab cov ntsiab lus tau teev nyob rau hauv tsab xov xwm tsis tau ua los ntawm lub site no. Lub vev xaib no tsis muaj kev cog lus lossis kev cog lus txog qhov tseeb, ua tiav, thiab sijhawm sijhawm ntawm tsab xov xwm no, tag nrho lossis ib feem ntawm cov ntsiab lus, thiab cov ntawv nyeem. Cov neeg nyeem tau raug caw los siv tsuas yog, thiab thov txheeb xyuas los ntawm lawv tus kheej cov ntaub ntawv ntsig txog.
Txawm hais tias tsis tau muaj ntau yam kev tsis sib haum xeeb hauv LED teb hauv Suav teb txij li" 337" kev tshawb nrhiav, cov kev pheej hmoo patent ntsib los ntawm Suav tuam txhab uas muag tsis raug txo, tab sis nyob rau hauv cov kav dej. Qee lub tuam txhab tau pib nqis tes los daws qhov teeb meem no. Yuav ua li cas los tsim ib lub tswv yim tsim nyog patent yuav muaj kev cuam tshuam rau kev noj qab haus huv ntawm Tuam Tshoj txoj kev lag luam LED
