Ua ntej tshaj, cia' s tham txog dab tsi yog tsav LED? Nws tuaj yeem hloov kho lub fais fab rau lub zog tshwj xeeb thiab tam sim no los tsav lub teeb hluav taws xob LED hluav taws xob hloov hluav taws xob. Feem ntau, cov tswv yim ntawm LED tsav lub zog muab hluav taws xob suav nrog cov ntsuas hluav taws xob ntau zaus AC (piv txwv li, lub ntsiab hluav taws xob), hluav taws xob DC tsawg, cov hluav taws xob DC, cov hluav taws xob tsawg-zaus AC. (xws li kev tawm ntawm kev hloov hluav taws xob). Kev tsim tawm ntawm tus tsav tsheb LED feem ntau yog qhov hloov chaw tam sim no uas hloov qhov hloov hluav taws xob raws li LED' s rau pem hauv ntej qhov hluav taws xob hloov pauv.
Cov tub ntxhais tseem ceeb ntawm cov hluav taws xob LED muaj xws li hloov maub los, kev siv lub hauv siab, lub pob hloov (MOSfet), cov kev tawm tsam rov tawm, cov khoom siv tawm ntawm cov khoom siv, cov khoom siv lim tawm, thiab cov zoo li. Raws li cov sijhawm sib txawv, yuav tsum muaj kev tiv thaiv overvoltage tiv thaiv Circuit Court, cov tswv yim tiv thaiv Circuit Court tiv thaiv Circuit Court, LED qhib kev tiv thaiv Circuit Court, tiv thaiv overcurrent thiab lwm yam kev ua haujlwm.
Dej num los ntawm tsav
(1) Hom tsis tu ncua tam sim no
Kev tsim tawm ntawm qhov hluav taws xob hloov ntawm qhov hluav taws xob tsav tas mus li tsis tu ncua, thiab DC qhov hluav taws xob ntawm cov zis hloov txawv nyob hauv qee qhov raws li qhov loj ntawm lub zog tsis kam. Lub load tsis kam yog me me, cov zis voltage yog tsawg, lub load kuj loj dua, thiab cov zis hluav taws xob kuj tseem siab dua;
Qhov hluav taws xob tas mus li tsis ntshai thauj khoom luv luv, tab sis nws raug txwv tsis pub qhib lub nra;
Cov hluav taws xob hluav taws xob hloov tam sim no tsav lub LED, uas yog qhov zoo, tab sis kuj siab nyob rau hauv nqe;
Xim yuav tsum tau them rau qhov siab tshaj qhov tam sim no thiab qhov muaj nuj nqis siv hluav taws xob, uas txwv cov lej ntawm LEDs siv.
(2) Kev tswj hwm qhov hluav taws xob
Thaum cov ntsuas hauv qhov hluav taws xob ceev qhov hluav taws xob raug txiav txim siab, cov zis hluav taws xob raug hloov kho, thiab cov zis tam sim no hloov raws li lub load nce lossis nqis;
Cov hluav taws xob hluav taws xob Circuit Court tsis ntshai lub load qhib Circuit Court, tab sis nws raug txwv tsis pub luv luv lub nra;
Tsav lub LED nrog qhov hluav taws xob uas muaj hluav taws xob rau kev tsav tsheb, txhua txoj hlua yuav tsum tau ntxiv nrog tus haum coj los ua kom txhua txoj hlua ntawm LED pom teeb pom kev nruab nrab;
Lub ci ci cuam tshuam los ntawm qhov hloov kho voltage.
LED tsav zog nta
(1) Muaj kev cia siab rau
Tshwj xeeb tshaj yog zoo li lub zog tsav tsheb ntawm LED txoj kev teeb txawb, nws tau nruab rau ntawm qhov chaw siab, kev saib xyuas tsis yooj yim, thiab tus nqi txij nkawm kuj tseem loj.
(2) Qhov ua haujlwm siab
LEDs yog lub zog txuag khoom, thiab kev ua haujlwm ntawm tsav tsheb fais fab khoom yog siab. Nws yog ib qho tseem ceeb heev rau dissipate tshav kub los ntawm lub hwj huam hluav taws xob tau teeb tsa nyob rau hauv lub fixture. Lub peev txheej muaj qhov ua tau zoo, nws lub zog siv hluav taws xob tsawg, thiab cov cua kub hauv lub teeb yog me me, uas txo qhov kub nce ntawm lub teeb. Nws tau txais txiaj ntsig los ncua lub hnub ci ntawm LEDs.
(3) Cov hwj huam loj
Lub zog muab hluav taws xob yog daim phiaj' s load yuav tsum. Feem ntau, cov cuab yeej siv hauv tsev qis dua 70 watt tsis muaj qhov ntsuas tsis pom. Txawm hais tias qhov teeb meem ntawm lub zog ntawm ib tus neeg siv hluav taws xob nrog lub zog qis me me muaj feem cuam tshuam rau daim phiaj siv hluav taws xob, cov teeb pom kev zoo siv thaum hmo ntuj yog loj, thiab cov thauj khoom zoo sib xws dhau lawm ntau, uas yuav ua rau muaj kuab paug loj rau lub zog daim phiaj. Txog 30 watts txog 40 watts ntawm LED tsav tsheb zog, nws tau hais tias nyob rau yav pem suab, muaj qee yam ntsuas rau lub zog hluav taws xob.
(4) Txoj kev tsav tsheb
Muaj ob hom kev tsheb: ib qho yog qhov ntsuas 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. Txoj kev no, kev sib xyaw ua ke yog hloov tau, thiab txhua qhov LED yuam kev tsis cuam tshuam rau kev ua haujlwm ntawm lwm LED, tab sis tus nqi yuav siab dua me ntsis. Tus tod yog qhov hluav taws xob tas mus li tam sim no, uas yog kev tsav tsheb tau pom zoo los ntawm "Zhongke Huibao". Cov LED raug khiav hauv kab lossis ua ib txhij. Nws cov txiaj ntsig yog tias tus nqi qis dua, tab sis qhov hloov tau tsis zoo, thiab nws yog qhov yuav tsum tau los daws qee qhov LED tsis ua haujlwm yam tsis muaj kev cuam tshuam ntawm kev ua haujlwm ntawm lwm LED. Ob hom ntawv no coexist ib pliag. Multi-channel tas mus li lub zog tso zis hluav taws xob hom yuav zoo dua ntawm cov nqi thiab kev ua haujlwm. Tej zaum nws yog cov kev coj hauv lub ntsiab hauv lub neej yav tom ntej.
(5) Kev tiv thaiv sab nrauv
Lub peev xwm ntawm LEDs los tiv thaiv kev ua haujlwm poob qis yog qhov tsis zoo, tshwj xeeb tshaj yog tiv thaiv hluav taws xob rov qab. Nws tseem yog qhov tseem ceeb los ntxiv dag zog rau kev tiv thaiv hauv thaj chaw no. Qee qhov teeb ci LED yog ntsia sab nraum zoov, xws li LED teeb lub teeb. Vim tias qhov pib ntawm daim phiaj thauj khoom thiab qhov induction ntawm xob laim, ntau yam kev tawm tsam yuav tawm los ntawm cov kab sib chaws, thiab qee qhov surges yuav ua rau LED puas. Yog li, kev txheeb xyuas" Zhongke Huibao" tsav lub zog hluav taws xob yuav tsum muaj qee qhov tsis muaj kev tiv thaiv kom tsis txhob muaj kev tiv thaiv, thiab vim tias lub zog hluav taws xob thiab cov teeb txawb hloov tau ntau zaus, LED tsav lub zog hluav taws xob yuav tsum muaj lub peev xwm los cuam tshuam kev nkag siab ntawm surges thiab tiv thaiv LED ntawm kev puas tsuaj.
(6) Kev tiv thaiv muaj nuj nqi
Ntxiv rau qhov kev tiv thaiv ib txwm ua, lub zog hluav taws xob zoo dua qhov ua rau LED kub tsis zoo lub tswv yim nyob rau hauv cov zis tam sim no los tiv thaiv LED qhov kub ntawm qhov ntsuas kub dhau; 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 kev hloov pauv tam sim no thiab txoj kev-los-channel cov haujlwm niaj hnub ua haujlwm
Piv nrog rau tag nrho qhov hloov tam sim no, tus nqi hluav taws xob tas li yog qhov tsis zoo thiab tus nqi siab dua. Tab sis nws muaj peev xwm tiag tiag tiv thaiv LED thiab ntev lub neej ntawm LED, yog li qhov tam sim no tas mus li yog kev sib tw yav tom ntej.
