Cua txias, tsav fais fab, lub teeb qhov ci yog qhov tseem ceeb ntawm kev tsim teeb pom kev zoo ntawm cov teeb pom kev zoo tshaj plaws ntawm cov teeb pom kev zoo. Txawm hais tias lub tshav kub tshwj xeeb tseem ceeb, qhov txias txias cuam tshuam ncaj qha rau lub neej ntawm cov teeb pom kev zoo khoom, tab sis lub teeb ci yog qhov tseem ceeb ntawm cov khoom muag, tsav lub hwj huam mov nws tus kheej, lub neej thiab cov zis tam sim no, qhov ruaj ntseg ntawm qhov khoom tag nrho Lub neej zoo kuj muaj kev cuam tshuam zoo heev.
LED tsav fais fab tseem yog ib tug complementary khoom, tam sim no lub zog zoo nyob rau hauv lub lag luam tsis ncaj ncees, cov nram qab no muab qee cov tsav LED tsav fais fab kev paub.
1. Lub kaus mom yog tus tsav lub teeb powe r
LED tsav fais fab kom hloov lub hwj huam los mus rau ib qho kev siv hluav taws xob thiab tam sim no los tsav cov teeb pom kev zoo ntawm lub teeb pom kev zoo xws li: LED tsav fais fab tuag, xws li high-voltage fais fab AC (ie, hluav taws xob), low voltage DC, high voltage DC, tsis tshua muaj hluav taws xob hloov (xws li cov hluav taws xob hluav taws xob) thiab lwm yam. Thaum cov tsav hluav taws xob tsav cov tsav hluav taws xob feem ntau nrog cov LED rau pem hauv ntej voltage hloov los hloov qhov voltage qhov chaw tam sim no. LED fais fab mov tub ntxhais muaj xws li hloov maub los, kev sib cog lus, hloov khoom (MOSFET), tawm tswv yim resistor, input lim, tso zis lim thiab hais txog. Raws li ntau lub sij hawm, tab sis kuj muaj cov tswv yim tiv thaiv kev tiv thaiv overvoltage, cov tswv yim kev tiv thaiv kev tiv thaiv kev tiv thaiv, LED qhib kev tiv thaiv kev tiv thaiv, kev tiv thaiv kev tiv thaiv thiab lwm yam kev sib cog lus.
2 . LED drive zog cov yam ntxwv
(1) H ncaj qha
Tshwj xeeb tshaj li LED teeb tsav fais fab, ntsia nruab nrab qhov siab tshaj plaws, txij nkawm tsis yooj yim, txij nkawm nqi kuj tseem loj.
(2) Ua haujlwm zoo
LED yog cov khoom txuag hluav taws xob, tsav hluav taws xob ua haujlwm zoo dua. Nws yog ib qho tseem ceeb rau lub hwj huam khoom muab ntsia rau hauv lub qhov rooj. Fais fab tuag yog qhov siab, nws lub hwj huam siv zog me me, nyob rau hauv lub teeb kub yog me me, nws yuav txo qhov teeb kub. Hloov cov teeb ci LED tsis ua haujlwm zoo.
(3) Huag zog tau
Qhov zoo tshaj yuav yog qhov khoom ntawm lub kab sib chaws. Feem ntau qis dua 70 watts ntawm cov khoom siv hluav taws xob, tsis muaj cov cim tseem ceeb. Txawm hais tias lub hwj huam tsis yog tib lub hwj chim tau qis dua cov hwj huam ua rau lub hwj chim loj, tiam sis siv ntau ntau lub teeb thaum hmo ntuj, tib hom kev thauj khoom dhau los ua ke, qhov kab sib chaws yuav tsim muaj cov pa phem ntau. Rau 30 watts mus 40 watts ntawm LED tsav fais fab, nws yog hais tias nyob rau hauv rau yav pem suab, tej zaum yuav muaj ib cov degree ntawm qhov yuav tsum tau muaj zog.
(4) tsav tsheb
Tam sim no muaj ob hom kev khiav tsheb: ib qho yog ib qho chaw qhov chaw nyob rau ib qhov chaw tam sim no qhov chaw, txhua qhov tam sim no qhov twg los tau rau txhua lub hwj huam hluav taws xob. Li no, ua ke ntawm saj zawg zog, tag nrho txoj kev LED tsis ua, tsis cuam tshuam rau kev ua haujlwm ntawm lwm tus LED, tab sis tus nqi yuav yog me ntsis siab dua. Qhov sib tw yog ib qho ncaj qha tam zog tam sim no yog "nyob rau hauv Chav Huibao" siv hom tsav, LED series los sis ua haujlwm ib yam. Nws qhov kom zoo dua yog qhov tsawg dua tus nqi, tab sis qhov yooj yim yog pluag, tab sis kuj yuav kom daws tau qhov tsis ua hauj lwm uas tsis ua hauj lwm, tsis cuam tshuam rau lwm yam lag luam hauv lub lag luam. Cov ob hom coexist rau ib lub sijhawm. Ntau cov channel tso zis hluav taws xob tam sim no, saib nqi thiab kev ua haujlwm yuav zoo dua. Tej zaum yav tom ntej ntawm lub hauv paus.
(5) Kev tiv thaiv kom zoo
LED tsis pub muaj peev xwm muaj peev xwm kuj yog cov neeg txom nyem, tshwj xeeb tshaj yog muaj peev xwm ua kom tsis muaj zog. Nws tseem ceeb kom ntxiv dag zog rau txoj kev tiv thaiv no. Muaj qee qhov teeb ci teeb nyob rau sab nraum zoov, xws li LED teeb. Vim yog lub nra ntawm cov kab sib tsoo thiab hluav taws xob induction, los ntawm kab sib chaws system yuav cuam tshuam ntau yam surges, thiab ib co surge yuav ua rau cov kev puas tsuaj rau LED. Yog li ntawd, qhov kev tshawb xyuas ntawm "Hauv Hu Ua Huib" tsav lub hwj chim ntawm kev tiv thaiv yuav tsum muaj ib qho tsis muaj, thiab raws li cov kev hloov ntawm lub zog thiab teeb pom kev zoo heev, LED tsav lub zog rau suppress lub surge ntawm intrusion, kev tiv thaiv ntawm LED yog tsis puas muaj peev xwm.
(6) P kev sib hloov
Fais fab mov Txuas ntxiv rau txoj kev tiv thaiv kev ruaj ntseg, nws yog qhov zoo tshaj plaws los ua kom muaj qhov tso zis zis tam sim no qhov ntsuas kub kub tsis zoo tawm tswv yim kom tiv thaiv tau qhov kub kub yog siab dhau; ua raws li kev nyab xeeb thiab kev tsim nyog yuav tsum muaj kev sib tw electromagnetic.
3 .Tau tsav tsheb
(1) tam sim no qhov tam sim no qhov tam sim no tsav qhov hluav taws xob tso ziag tam sim no, thiab qhov hluav taws xob ntawm DC voltage nrog cov load kuj ntawm qhov sib txawv ntawm cov kev hloov hauv ib cheeb tsam, lub load kuj me me, cov zis voltage tsawg, load tsis kam Lub teeb meem tam sim no lub voj voog tam sim no yog qhov zoo tagnrho, tab sis tus nqi siab; yuav tsum tau them sai sai rau kev siv ntawm lub siab tshaj plaws niaj hnub siv tam sim no thiab kev siv ntawm qhov tam sim no yog siab heev, qhov siab zog qhov tso zis hluav taws xob dua; qhov tam sim no Circuit Court tam sim no tsis ntshai ntawm luv luv Circuit Court, Voltage tus nqi, uas txwv cov xov tooj ntawm cov LEDs siv.
(2) R egulator voltage regulator Circuit nyob rau hauv cov kev txiav txim siab, cov zis hluav taws xob yog tsau, thiab cov zis tam sim no nrog cov load nce los yog txo; voltage regulator Circuit Court tsis ntshai ntawm load qhib, tab sis lub load yog nruj me ntsis Circuit Court luv; los tsav cov tsav xwm tsav tsheb tsav cov LED, txhua txoj hlua xav ntxiv qhov tsim nyog rau txhua txoj hlua LED teeb ci ci nruab nrab; qhov ci yuav muaj kev cuam tshuam los ntawm kev rectification ntawm cov kev hloov voltage.
4 .Tus nws tseem niaj hnub tamsim no thiab tas mus li tam sim no kev soj ntsuam txog qhov zoo thiab qhov tsis zoo
Muab piv rau tas nrho qhov tam sim no, txoj kev tsheb tam sim no txawm hais tias qhov tsis txaus ntseeg yog tus nqi ntau dua. Tab sis nws muaj peev xwm tiag tiag ua tus tiv thaiv LED thiab ntev rau lub neej ntawm cov LED, yog li txoj kev yog qhov kev sib tham yav tom ntej ntawm qhov tam sim no.
5 . LED fais fab tsis muaj zog
LED tsav fais fab tuag yog tam sim no undercritical:
Ua ntej, cov teeb pom kev zoo ntawm cov teeb pom kev zoo thiab cov khoom siv hauv lub tuam txhab, lub tuam txhab kev ua hauj lwm ntawm cov khoom siv hluav taws xob tsis nkag siab txog lub zog ua haujlwm, tab sis qee qhov kev ntsuam xyuas thiab kev sib txuas ntawm electromagnetic tsis txaus, ;
Thib ob , feem ntau ntawm cov fais fab mov khoom lag luam yog hloov los ntawm qhov dog dig switching fais fab mov ua fais fab tuag, cov yam ntxwv ntawm kev siv ntawm LED thiab kev nkag siab tsis txaus;
Qhov thib peb , tus txheej txheem tam sim no ntawm cov LED yuav luag tsis muaj, feem ntau ntawm cov kev siv hloov khoom siv fais fab thiab cov qauv siv hluav taws xob rectifier; tam sim no feem ntau ntawm cov fais fab tuag mov tsis yog yam tsis, yog li feem ntau ntawm cov me. Purchase volume yog tsawg, tus nqi siab, thiab kev tivthaiv cov chaw muag khoom tsis nrog rau;
Qeb plaub , kev ruaj ntseg ntawm cov hluav taws xob ntawm lub cev: qhov dav voltage input, kub thiab kub ua hauj lwm, tshaj kub, tiv thaiv overvoltage thiab lwm yam teeb meem tsis daws ib qho los ntawm ib.
Thawj yog lub neej tag nrho ntawm cov tsav tsheb, tshwj xeeb tshaj yog lub tswv yim tseem ceeb xws li: lub neej ntawm lub capacitor ntawm high kub ncaj qha mus rau lub neej ntawm lub hwj chim; LED tsav yuav tsum twv qhov kev hloov siab dua, tshwj xeeb tshaj yog nyob rau hauv tsav lub hwj huam LED tshaj li ntawd, vim tias tag nrho cov fais fab tuag tsis yog ib lub teeb tso tawm raws li cua sov dissipation, hluav taws xob conversion efficiency tsawg dhau, cuam tshuam cov teebmeem energy-saving effect. Tam sim no nyob rau hauv cov kev siv zog me me (1-5W), qhov feem pua ntawm cov nqi tam sim no cov nqi zog tam sim no muaj ze li ntawm 1/3, tau ze rau tus nqi ntawm lub teeb ci, rau qee qhov cuam tshuam rau kev lag luam.
