Ua ntej tshaj, cia' s tham txog dab tsi yog LED tsav tsheb hwj chim? Nws tuaj yeem hloov kho lub hwj huam hluav taws xob rau hauv tshwj xeeb voltage thiab tam sim no los tsav lub LED voltage hloov pauv. Feem ntau, cov tswv yim ntawm LED tsav lub zog suav nrog cov hluav taws xob ntau hluav taws xob ntau zaus AC (uas yog, lub zog tseem ceeb), hluav taws xob tsawg DC, cov hluav taws xob DC, cov hluav taws xob tsawg, cov hluav taws xob tsawg zaus AC (Xws li cov khoom hluav taws xob hloov hluav taws xob) Cov. Cov zis ntawm lub zog tsav tsheb LED feem ntau yog qhov hloov chaw tam sim no uas tuaj yeem hloov qhov voltage li lub zog pem hauv ntej poob ntawm LED hloov pauv.
LED fais fab tub ntxhais cov khoom siv muaj xws li hloov maub los, inductors, hloov khoom siv (MOSfet), tawm tswv yim resistors, cov khoom siv lim tawm, cov khoom siv lim tawm, thiab lwm yam. Raws li cov tseev kom muaj ntawm cov sib txawv, yuav tsum muaj kev tiv thaiv overvoltage tiv thaiv Circuit Court, cov tswv yim tiv thaiv Circuit Court tiv thaiv, LED qhib kev tiv thaiv Circuit Court, tiv thaiv overcurrent thiab lwm qhov Circuit Court.
Kev faib tawm los ntawm hom kev tsav tsheb
(1) tsis tu ncua tam sim no
Cov zis tawm ntawm cov hluav taws xob hloov ntawm lub tshuab hluav taws xob tas li tsis tu ncua, tab sis cov txiaj ntsig DC voltage hloov tsis pub dhau ib qho tshwj xeeb nrog qhov loj ntawm cov load tsis kam. Qhov me dua qhov kev tawm tsam, qhov qis dua cov zis voltage, thiab qhov loj dua ntawm kev thauj mus los, qhov hluav taws xob tso zis ntau dua. Lub siab dua
Circuit Court tsis tu ncua tam sim no tsis ntshai ntawm kev thauj khoom luv luv Circuit Court, tab sis nws yog nruj me ntsis txwv tsis pub lub luag haujlwm ntawm lub Circuit Court qhib tag nrho;
Cov tsav hluav taws xob tsis tu ncua tam sim no zoo tagnrho rau tsav LED, tab sis tus nqi kuj tseem siab;
Ua tib zoo saib rau qhov tam sim no thiab qhov siv hluav taws xob ntau, uas txwv cov lej ntawm LEDs siv.
(2) Tsim los tswj
Tom qab qhov ntsuas ntawm qhov voltage stabilization Circuit Court raug txiav txim siab, cov zis hluav taws xob tau hloov kho, tab sis cov zis tam sim no hloov nrog qhov nce thiab txo ntawm lub nra;
Qhov hluav taws xob hluav taws xob hluav taws xob thaiv tsis txaus ntshai ntawm qhov qhib Circuit Court ntawm lub nra, tab sis nws yog nruj me ntsis txwv tsis pub kom luv luv ua tiav lub nra;
Tsav lub LEDs nrog lub ntsuas hluav taws xob kom ruaj khov. Koj yuav tsum ntxiv cov tsis kam tiv taus rau txhua txoj hlua los ua txhua txoj hlua ntawm LED pom qhov nruab nrab qhov ci ntsa iab;
Qhov ci ci yog cuam tshuam los ntawm kev hloov pauv voltage los ntawm kev txhim kho kom zoo.
Cov yam ntxwv ntawm LED tsav fais fab
(1) Muaj kev cia siab rau
Nws yog qhov tshwj xeeb zoo li lub zog tsav hluav taws xob rau LED txoj kev teeb, uas tau teeb tsa ntawm qhov chaw siab, uas tsis yooj yim rau kev saib xyuas thiab tus nqi txij nkawm tseem loj.
(2) Qhov ua haujlwm siab
LED yog lub zog txuag hluav taws xob, thiab qhov ua tau zoo ntawm lub zog tsav tsheb yuav tsum siab. Nws yog qhov tseem ceeb rau kev nthuav tawm cua sov ntawm cov hlws ris uas qhov chaw fais fab tuag tau nruab rau hauv lub luminaire. Qhov ua tau zoo ntawm lub zog fais fab yog loj, nws lub zog siv hluav taws xob yog tsawg, kev tsim hluav taws xob hauv lub teeb yog me me, thiab qhov kub nce ntawm lub teeb tau tsawg. Nws muaj txiaj ntsig zoo rau kev ncua lub hnub ci ntawm LED.
(3) Cov hwj huam loj
Lub zog fais fab yog qhov yuav tsum tau ntim ntawm lub zog daim phiaj. Feem ntau, tsis muaj lub ntsuas tsim nyog rau khoom siv hauv tsev neeg qis dua 70 watts. Txawm hais tias qhov kev siv hluav taws xob ntawm ib tus neeg siv nrog lub zog me me tau qis dua, nws muaj tsawg cuam tshuam rau ntawm daim phiaj fais fab. Txawm li cas los xij, thaum tsaus ntuj, qhov ntau ntawm cov teeb pom kev zoo yog qhov loj, thiab cov khoom sib xws zoo dhau lawm, uas yuav ua rau muaj kuab paug rau lub zog daim phiaj. Txog 30W txog 40W LED tsav zog, nws tau hais tias nyob rau yav tom ntej ze, muaj qee qhov ntsuas qhov xav tau rau lub zog hluav taws xob.
(4) Txoj kev tsav tsheb
Muaj ob hom kev khiav tsheb tam sim no: ib qho yog qhov tso tawm qhov hluav taws xob rau ntau qhov chaw tsis tu ncua, thiab txhua qhov hluav taws xob tam sim no muab lub zog rau txhua LED sib cais. Ua li no, kev sib xyaw ua ke yog hloov tau, thiab LED tsis ua raws txoj kev yuav tsis cuam tshuam rau kev ua haujlwm ntawm lwm LED, tab sis tus nqi yuav siab me ntsis. Lwm qhov yog cov hluav taws xob ncaj qha tam sim no, uas yog txoj kev tsav tsheb tau pom zoo los ntawm" Zhongke Huibao" ;. Cov LED khiav khiav hauv kab lossis ua ib txhij. Nws txoj kev zoo dua yog tus nqi qis dua, tab sis kev hloov pauv tsis zoo. Nws tseem yuav tsum tau daws qhov teeb meem ntawm ib qho LED tsis ua hauj lwm, uas tsis cuam tshuam rau kev ua haujlwm ntawm lwm LED. Ob daim foos no yog sib dhos ua ntu zus. Multi-channel tas mus li lub zog tso zis hluav taws xob cov qauv yuav zoo dua ntawm cov nqi thiab kev ua haujlwm. Tej zaum lub ntsiab kev taw qhia yav tom ntej.
(5) Kev tiv thaiv sab nrauv
Cov peev txheej tiv thaiv hluav taws xob ntawm LED yog qhov tsis tshua zoo, tshwj xeeb tshaj yog qhov rov qab ua hluav taws xob muaj peev xwm. Nws tseem yog qhov tseem ceeb ntxiv dag zog rau kev tiv thaiv no. Qee qhov teeb ci LED yog ntsia sab nraum zoov, xws li LED teeb lub teeb. Vim tias qhov induction ntawm daim phiaj load thiab induction ntawm xob laim ntaus, ntau surges yuav invade los ntawm kab sib chaws, thiab qee surges yuav ua kev puas tsuaj rau LEDs. Yog li, kev txheeb xyuas" Zhongke Huibao" tsav lub zog hluav taws xob yuav tsum muaj qee qhov kev poob qis ntawm kev tiv thaiv kev nce qib. Raws li rau kev hloov ntau zaus ntawm cov khoom siv hluav taws xob thiab cov teeb txawb, cov tsav tsheb LED tsav fais fab yuav tsum muaj lub peev xwm los tiv thaiv kev nkag los ntawm kev hla thiab tiv thaiv LED ntawm kev puas tsuaj.
(6) Kev tiv thaiv muaj nuj nqi
Ntxiv rau cov txheej txheem tiv thaiv ib txwm ua haujlwm, nws yog qhov zoo tshaj rau ntxiv cov lus tsis zoo ntawm LED kub rau qhov tso zis tawm tam sim no los tiv thaiv LED qhov kub tsis dhau los ua qhov siab; nws yuav tsum ua kom tau raws li cov tseev kom muaj ntawm kev nyab xeeb cov cai thiab electromagnetic sib xyaw.
Qhov zoo thiab qhov tsis zoo ntawm txhua qhov sib txawv ntawm qhov tam sim no thiab txoj kev-los-channel tas li cov kev ua haujlwm tam sim no
Piv nrog rau tag nrho qhov hloov tam sim no, txawm hais tias qhov hloov tam sim no los ntawm ib qho channel mus rau lwm qhov muaj ntau qhov tsis zoo, tus nqi kuj tseem siab dua. Txawm li cas los xij, nws muaj peev xwm tiv thaiv LED tseeb thiab txuas lub neej ntawm LED, yog li qhov tam sim no yog qhov sib hloov yav tom ntej.
