LED lub teeb txuag hluav taws xob yog cov ntsiab lus dav dav rau kev lag luam, thiab muaj ntau yam khoom sib faib, xws li LED txoj kev teeb, LED qhov teeb, LED siab bay teeb, LED fluorescent teeb thiab LED vaj huam sib luag teeb.Tam sim no, lub lag luam tseem ceeb ntawm LED lub teeb txuag hluav taws xob tau maj mam hloov los ntawm txawv teb chaws mus rau lub ntiaj teb no, thiab xa mus rau txawv teb chaws kev lag luam yuav tsum dhau qhov kev soj ntsuam, thaum lub domestic LED teeb txuag hluav taws xob specifications thiab cov qauv yuav tsum nruj dua, yog li ntawd. Kev kuaj ntawv pov thawj tau dhau los ua haujlwm ntawm LED teeb manufacturers.tsom.Cia kuv qhia rau koj txog 8 lub ntsiab lus tseem ceeb ntawm LED lub zog txuag hluav taws xob kuaj cov qauv:
1. Khoom siv
LED lub zog txuag hluav taws xob tuaj yeem ua rau ntau yam duab xws li lub raj kheej kheej kheej kheej.Coj ncaj tube LED fluorescent teeb ua piv txwv.Nws cov duab zoo ib yam li cov raj fluorescent zoo tib yam.nyob rau hauv . Lub plhaub pob tshab polymer muab hluav taws kub thiab hluav taws xob tiv thaiv hauv cov khoom.Raws li tus qauv xav tau, cov khoom siv plhaub ntawm lub teeb txuag hluav taws xob yuav tsum ncav cuag V-1 qib lossis siab dua, yog li lub plhaub pob tshab polymer yuav tsum tau ua los ntawm V-1 qib lossis siab dua.Yuav kom ua tiav qib V-1, lub thickness ntawm cov khoom plhaub yuav tsum ntau dua los yog sib npaug ntawm cov thickness uas yuav tsum tau V-1 qib ntawm cov khoom siv raw.Qhov ntsuas hluav taws kub thiab qhov xav tau tuab tuaj yeem pom ntawm UL daim npav daj ntawm cov khoom siv raw.Txhawm rau kom ntseeg tau tias lub teeb ci ntawm LED lub zog txuag hluav taws xob, ntau lub tuam txhab feem ntau ua rau cov pob tshab polymer lub plhaub nyias nyias, uas yuav tsum muaj tus kws tshuaj xyuas xyuas kom paub tseeb tias cov khoom ua tau raws li qhov xav tau ntawm qhov ntsuas hluav taws kub.
2. poob xeem
Raws li qhov yuav tsum tau ua ntawm tus qauv khoom, cov khoom yuav tsum tau sim los ntawm simulating qhov poob qhov xwm txheej uas yuav tshwm sim hauv cov txheej txheem siv tiag tiag.Cov khoom yuav tsum tau muab tshem tawm los ntawm qhov siab ntawm 0.91 meters mus rau lub hardwood board, thiab cov khoom plhaub yuav tsum tsis txhob raug tawg kom nthuav tawm qhov txaus ntshai nyob rau hauv.Thaum cov chaw tsim khoom xaiv cov khoom siv rau lub plhaub khoom, nws yuav tsum ua qhov kev sim no ua ntej kom tsis txhob poob los ntawm kev ua tsis tiav ntawm cov khoom loj.
3. Dielectric zog
Lub pob tshab casing encloses lub hwj chim module nyob rau hauv, thiab cov pob tshab casing khoom yuav tsum tau raws li qhov yuav tsum tau ntawm hluav taws xob lub zog.Raws li cov qauv kev cai, raws li North American voltage ntawm 120 volts, lub sab hauv high-voltage nyob qhov chaw thiab cov txheej casing (them nrog cov ntawv hlau rau kev ntsuam xyuas) yuav tsum muaj peev xwm tiv taus lub zog hluav taws xob ntawm AC 1240 volts.Raws li ib txwm muaj, lub thickness ntawm cov khoom plhaub ncav cuag li 0.8 hli, uas tuaj yeem ua tau raws li qhov yuav tsum tau muaj ntawm qhov kev ntsuas hluav taws xob no.
4. fais fab module
Lub zog hluav taws xob yog ib feem tseem ceeb ntawm LED lub zog txuag hluav taws xob, thiab lub zog hluav taws xob feem ntau yog siv lub tshuab hluav taws xob hloov hluav taws xob.Raws li ntau hom fais fab modules, cov qauv sib txawv tuaj yeem raug txiav txim siab rau kev kuaj thiab ntawv pov thawj.Yog hais tias lub hwj chim module yog chav kawm II fais fab mov, qhov no tuaj yeem kuaj thiab lees paub nrog UL1310.Class II fais fab mov yog hais txog lub hwj huam mov nrog kev sib cais transformer, cov zis voltage qis dua DC 60V, thiab tam sim no tsawg dua 150 / Vmax ampere.Rau cov khoom siv hluav taws xob tsis yog chav kawm II, UL1012 yog siv rau kev kuaj thiab ntawv pov thawj.Cov kev cai ntawm ob tus qauv no zoo sib xws thiab tuaj yeem xa mus rau ib leeg.Feem ntau ntawm cov khoom siv hluav taws xob sab hauv ntawm LED lub zog txuag hluav taws xob siv cov khoom siv hluav taws xob uas tsis yog cais tawm, thiab cov zis DC ntawm lub zog hluav taws xob kuj tseem ntau dua 60 volts.Yog li, tus qauv UL1310 tsis siv tau, tab sis UL1012 muaj feem xyuam.
5. Cov kev xav tau ntawm rwb thaiv tsev
Vim muaj qhov txwv sab hauv ntawm LED lub teeb txuag hluav taws xob, kev saib xyuas yuav tsum tau them rau cov txheej txheem rwb thaiv tsev ntawm cov khoom siv phom sij thiab cov khoom siv hlau siv tau thaum lub sij hawm tsim qauv.Rwb thaiv tsev tuaj yeem yog qhov chaw nyob deb thiab nkag mus deb lossis cov ntawv insulating.Raws li tus qauv yuav tsum tau muaj, qhov chaw nyob deb ntawm qhov chaw muaj kev phom sij thiab cov khoom siv hlau siv tau yuav tsum ncav cuag 3.2 hli, thiab qhov deb ntawm qhov nkag yuav tsum ncav cuag 6.4 hli.Yog tias qhov kev ncua deb tsis txaus, ib daim ntawv insulating tuaj yeem muab ntxiv ua cov rwb thaiv tsev ntxiv.Lub thickness ntawm cov ntawv insulating yuav tsum siab tshaj 0.71 hli.Yog tias qhov tuab tsawg dua 0.71 hli, cov khoom yuav tsum tuaj yeem tiv taus qhov ntsuas hluav taws xob siab ntawm 5000V.
6. ntsuas kub nce
Kev ntsuas kub nce siab yog qhov yuav tsum tau ua rau kev ntsuas kev nyab xeeb ntawm cov khoom.Tus qauv muaj qee qhov ntsuas kub nce siab rau cov khoom sib txawv.Nyob rau hauv cov khoom tsim theem, cov chaw tsim khoom yuav tsum tau muab qhov tseem ceeb ntawm cov khoom cua kub dissipation, tshwj xeeb tshaj yog rau qee qhov chaw (xws li cov ntawv insulating, thiab lwm yam) yuav tsum tau them nyiaj tshwj xeeb.Qhov chaw raug kub hnyiab rau lub sijhawm ntev tuaj yeem hloov pauv lawv lub cev, tsim kom muaj hluav taws kub lossis hluav taws xob.Lub hwj chim module nyob rau hauv lub luminaire nyob rau hauv ib tug kaw thiab nqaim qhov chaw, thiab lub tshav kub dissipation yog txwv.Yog li ntawd, thaum cov neeg tsim khoom xaiv cov khoom, lawv yuav tsum tau them sai sai rau kev xaiv cov kev qhia tshwj xeeb ntawm cov khoom tsim nyog los xyuas kom meej tias cov khoom ua haujlwm nrog qee cov npoo, kom tsis txhob overheating los ntawm cov khoom ua haujlwm nyob rau hauv cov xwm txheej ze rau tag nrho cov load rau ntev. sij hawm.
7. qauv
Txhawm rau kom txuag tau tus nqi, qee lub tuam txhab teeb pom kev lag luam LED solder qhov chaw ntawm tus pin-hom Cheebtsam ntawm PCB, uas tsis tsim nyog.Nto-soldered pin-hom Cheebtsam yuav poob tawm vim virtual soldering thiab lwm yam laj thawj, ua rau muaj kev phom sij.Yog li ntawd, txoj kev siv lub qhov (socket) vuam txoj kev yuav tsum tau txais kom deb li deb tau rau cov khoom no.Yog tias qhov chaw vuam tsis tuaj yeem zam tau, cov khoom siv yuav tsum tau muab "L taw" thiab kho nrog cov kua nplaum los muab kev tiv thaiv ntxiv.
8. kev xeem ua tsis tiav
Cov khoom tsis ua hauj lwm kuaj yog ib yam khoom uas tsim nyog heev hauv kev xeem ntawv pov thawj khoom.Cov khoom kuaj no yog luv luv lossis qhib qee cov khoom ntawm kab los simulate qhov ua tsis tau zoo thaum siv tiag tiag, txhawm rau ntsuas kev nyab xeeb ntawm cov khoom nyob rau hauv ib qho kev txhaum.Yuav kom ua tau raws li qhov yuav tsum tau muaj kev nyab xeeb no, thaum tsim cov khoom, nws yog ib qho tsim nyog yuav tsum xav txog kev ntxiv cov fuse tsim nyog rau qhov kawg ntawm cov khoom los tiv thaiv overcurrent los ntawm qhov tshwm sim tsis zoo xws li cov khoom siv hluav taws xob luv luv thiab cov khoom siv sab hauv tsis ua haujlwm, uas yuav ua tau mus tua hluav taws.
