1, dab tsi yog coj tsav lub zog
LED tsav fais fab mov los hloov cov khoom ntawm cov khoom siv fais fab mus rau ib qho tam sim no los tsav cov teeb pom kev zoo hluav taws xob ntawm cov roj teeb hluav taws xob, feem ntau: LED tsav fais fab input xws li high-voltage frequencies txauv (xws li, mains), Low-voltage DC, voltage DC, low-voltage high-frequency communication (xws li cov hluav taws xob tso hluav taws xob). Thiab cov zis ntawm cov tsav hluav taws xob tsav yog qhov feem ntau qhov tam sim no qhov chaw uas yuav hloov qhov voltage nrog qhov siab siab poob nqi ntawm cov LED. LED fais fab mov tub ntxhais muaj xws li kev hloov pauv, kev sib dhos, cov khoom hloov (MOSFET), tawm tswv yim resistors, cov khoom siv hluav taws xob, cov khoom siv hluav taws xob thiab lwm yam. Raws li qhov yuav tsum muaj ntawm ntau zaus, tab sis kuj muaj cov tswv yim tiv thaiv kev tiv thaiv overvoltage, cov tswv yim kev tiv thaiv kev tiv thaiv ntawm kev tiv thaiv, coj qhib txoj kev tiv thaiv kev tiv thaiv, kev tiv thaiv kev tiv thaiv overflurrent.
2, coj tsav cov yam ntxwv zog
(1) Kev ntseeg siab
Tshwj xeeb tshaj li LED txoj kev teeb tsa tsav fais fab, ntsia tau nruab nrab ntawm qhov chaw siab tshaj, kev txuag tsis yooj yim, kev them nqi yog ib qho tseem ceeb.
(2) Kev ua haujlwm siab
LED yog cov khoom siv txuag hluav taws xob, kev ua haujlwm ntawm kev tsav tsheb yog siab. Nws yog ib qho tseem ceeb rau lub hwj chim muab nruab rau hauv lub teeb. Kev ua haujlwm ntawm lub hwj huam yog siab, nws lub hwj huam siv zog me me, qhov kub hauv lub teeb yog me me, thiab qhov kub ntawm qhov teeb yog txo qis. Nws yog qhov zoo rau kev txo qeeb hauv cov teeb ci ntawm lub teeb ci.
(3) High power tau
Fais fab xwm txheej yog qhov yuav tsum tau muaj fais fab kab xaib. General 70 Watts hauv qab fais fab, tsis muaj qhov qhia tau tias tseem ceeb. Txawm hais tias lub hwj chim ntawm cov hluav taws xob tsawg tsawg ntawm cov hluav taws xob tsis yog qhov me me rau ntawm lub hwj chim, tiam sis kev siv teeb pom kev thaum hmo ntuj, tib hom kev thauj khoom dhau los, lub network yuav tsim muaj cov pa phem ntau. Rau 30 Watts ~ 40 Watt LED tsav fais fab tuag, nws tau hais tias yav tom ntej, tej zaum yuav muaj qee qhov yuav tsum tau ua raws li cov cai tswjfwm.
(4) Tsav hom
Muaj ob hom kev tam sim no: ib qho yog qhov chaw muaj qhov muaj zog rau ntau qhov tam sim no qhov chaw, txhua qhov chaw tam sim no nyob ib leeg rau txhua qhov tau txais hluav taws xob. Ua li no, kev sib xyaw ua ke, kev txhaum ntawm lub cev, tsis ua hauj lwm ntawm lwm cov LEDs, tab sis tus nqi yuav yog me ntsis siab dua. Lwm qhov yog qhov ncaj qha tam zog tam sim no yog "Zhong Ke hui Bao" hloov los ntawm tus tsav tsheb hom, LED series los yog cov txheej txheem ua haujlwm. Nws zoo yog cov uas tsis muaj nqi, tab sis qhov yooj tsis zoo, tab sis kuj yuav kom daws tau qhov teebmeem LED, tsis muaj teebmeem rau lwm yam teeb meem ua haujlwm. Cov ob hom no coexist dhau ib lub sijhawm. Ntau txoj hauv kev tso tawm tam sim no tso tawm fais fab mov, hom nqi thiab kev ua haujlwm yuav zoo dua. Tej zaum nws yog txoj kev coj loj tom ntej.
(5) Kev tiv thaiv kom zoo
LED surge kuj yog tus neeg txom nyem, tshwj xeeb tshaj yog lub peev xwm los tiv thaiv qhov rov qab rov qab. Nws yog ib qho tseem ceeb kom muaj kev tiv thaiv nyob hauv cheeb tsam no. Qee qhov teeb cig luaj teeb raug tawm sab nraud, xws li LED teeb rooj. Vim yog lub hauv paus ntawm lub hauv paus thiab cov hluav taws xob, ntawm lub kab sib chaws yuav ua rau muaj ntau yam kev hloov, qee qhov kev tawm tsam yuav ua rau kev puas tsuaj rau LED. Yog li ntawd, kev tshawb xyuas ntawm "Zhong Ke hui bao" tsav lub hwj chim ntawm kev tiv thaiv yuav tsum muaj ib qho tsis muaj, thiab raws li lub hwj huam thiab cov roj teeb heev hloov, LED tsav fais mov rau inhibit surge intrusion, tiv thaiv cov LED tsis puas muaj peev xwm.
(6) Kev tiv thaiv ua haujlwm
Ntxiv rau qhov kev tiv thaiv zoo li qub, nws yog qhov zoo tshaj kom nce cov ntsuas kub kub tsis zoo hauv qhov teeb meem tam sim no kom tiv thaiv tau qhov ntsuas kub ntawm kev siab dhau; kom tau raws li cov cai ntawm kev nyab xeeb thiab kev sib tw electromagnetic.
3, los ntawm kev tsav tsheb hom kev qhia
(1) tsis tu ncua
Tsawg ntawm cov tsav hluav taws xob tso tawm tam sim no, thiab qhov tso zis ntawm DC voltage nrog lub load tsis kam ntawm ntau ntau thiab tsawg ntawm cov kev hloov hauv load kuj yog me me, cov zis voltage tsawg tsawg, lub siab dua qhov load tsis kam, siab dua cov zis hluav taws xob ;
Tsawg tam sim no Circuit Court tsis ntshai ntawm luv luv luv Circuit Court, tab sis nruj me me txwv tsis pub lub load tag nrho qhib;
Qhov teeb meem tam sim no tsav lub voj voog tsav cov LED zoo tagnrho, tab sis tus nqi siab;
Kev ceeb toom yuav tsum tau them rau qhov siab tshaj plaws ntawm cov khoom tam sim no thiab cov nqi voltage, uas txwv cov LEDs siv.
(2) Txuj muag hom
Thaum qhov tsis ntawm qhov Circuit Court voltage stabilizing txiav txim siab, qhov output voltage yog tsau, thiab cov zis tawm tam sim no hloov nrog qhov nce thiab thawj ntawm cov load.
Voltage regulator Circuit yog tsis ntshai ntawm lub pob qhib, tab sis nruj me ntsis txwv ntsig txog luv luv;
Yuav kom tswj tau tus tsav tsheb khiav tsav cov LED, txhua txoj hlua xav tau los ua ke nrog cov lus qhia uas tsis zoo los ua txhua qhov screen brightness nruab nrab;
Qhov ci ntsa iab yog cuam tshuam los ntawm qhov kev hloov ntawm qhov hloov ntawm qhov hloov.
4. Qhov zoo thiab qhov tsis zoo ntawm tag nrho qhov niaj hnub tam sim no thiab txoj kev uas niaj hnub ua haujlwm tam sim no
Piv nrog rau tag nrho cov theem tam sim no, Lu Henglui yog qhov nyuaj thiab qhov nqi ntau dua. Tab sis nws tuaj yeem ua si kom tiv thaiv tau qhov LED thiab kom ntev mus rau lub neej ntawm cov LED, yog li qhov kev khiav dejnum ntawm txoj kev yog lub neej yav tom ntej.
5, tsis muaj lub hwjchim ntawm cov hluav taws xob LED
LED Tsav khoom fais fab Muaj ntau yam tsis txaus:
Qhov tsim ntawm LED teeb pom kev zoo thiab lwm yam khoom siv ntawm lub tuam txhab cov neeg ua hauj lwm ntawm cov neeg ua hauj lwm rau cov khoom siv hluav taws xob yuav tsis txaus los ua hluav taws xob tuaj yeem ua haujlwm, tab sis qee qhov kev soj ntsuam tseem ceeb thiab electromagnetic compatibility tsis txaus, lossis muaj qee qhov teeb meem;
Feem ntau ntawm cov hluav taws xob fais fab kev lag luam los ntawm cov khoom siv hluav taws xob coj los ua lub hwj huam ua hluav taws xob, cov yam ntxwv ntawm LED thiab kev siv kev paub tsis txaus;
Tam sim no, muaj ob peb cov qauv txog LEDs, lawv feem ntau yog siv kev hloov khoom siv fais fab thiab cov qauv siv hluav taws xob rectifier;
Tam sim no feem ntau cov hwj huam hluav taws xob tsis yog sib koom ua ke, vim li ntawd qhov ntim tsawg dua. Tus nqi yuav tsawg, qhov nqi yog siab, dhau ntawm tus tiv thaiv kev pab kuj tsis koom tes;
LED fais fab mov Kev ruaj ntseg: dav input voltage, kub thiab kub ua hauj lwm, dhau ntsuas kub, dhau qhov teeb meem tiv thaiv tsis yog ib qho los ntawm ib qho los daws teeb meem;
Ua ntej, tag nrho lub neej ntawm kev tsav tsheb, tshwj xeeb tshaj yog cov cuab yeej tseem ceeb xws li: lub peev xwm ntawm kev kub tau ncaj qha mus rau lub neej ntawm lub hwj chim;
Yog tus tsav tsheb tsav yuav tsum twv qhov kev hloov siab dua siab, tshwj xeeb tshaj yog nyob rau hauv kev tsav lub zog muaj zog thaum ntau dua, vim tias tag nrho lub zog tsis yog qhov tsim teeb ntawm lub teeb cua sov, kev hloov hluav taws xob ua hauj lwm tsawg dhau, qhov teeb meem ntawm LED kev txuag lub zog ntawm kev ua si;
Tam sim no, nyob rau hauv daim ntawv thov ntawm lub hwj chim me (1-5w), qhov feem cuam ntawm lub zog tam sim no lub zog muaj ze li ntawm 1/3, uas tau nyob ze rau tus nqi ntawm lub teeb ci, thiab tau cuam tshuam cov kev nce qib kev lag luam.
