Txhawm rau xam cov khoom siv hluav taws xob hloov pauv uas xav tau rau lub vijtsam LED zaub, koj yuav tsum ntsuas qhov tam sim no ntawm ib qho LED module, tom qab ntawd xam cov naj npawb ntawm cov khoom siv hluav taws xob ib leeg tuaj yeem siv hluav taws xob raws li cov khoom siv hluav taws xob, thiab thaum kawg txiav txim siab cov khoom siv hluav taws xob xav tau raws li tag nrho cov naj npawb ntawm cov zaub screen modules. Cov kauj ruam tshwj xeeb yog raws li nram no:
Ntsuas qhov tam sim no ntawm ib qho LED Module
** Cov Khoom Siv Yuav Tsum Tau:** Npaj lub LED zaub screen module los kuaj (piv txwv li, P10-4S sab nraum zoov LED zaub screen module), multimeter muaj peev xwm ntsuas DC tam sim no mus txog 10A, ob peb cov xov hlau, hluav taws xob daim kab xev, xaim strippers, LED zaub screen tswj daim npav, thiab LED zaub screen fais fab mov.
Correct Wiring: Txuas lub multimeter nyob rau hauv series nrog LED module kev khiav hauj lwm Circuit Court. Cov kab ke tshwj xeeb yog raws li hauv qab no:
** Txuas lub AC 220V rau lub LED fais fab input davhlau ya nyob twg.**
** Txuas ib lub xov hlau los ntawm qhov zoo tso zis davhlau ya nyob twg mus rau liab sojntsuam (zoo davhlau ya nyob twg) ntawm lub multimeter.**
** Txuas lub xov tooj liab rau hauv liab "10A" jack ntawm multimeter.**
** Txuas cov kev sojntsuam dub rau cov xaim liab (qhov zoo tshaj plaws) ntawm lub module lub hwj chim cable.**
** Txuas lub module lub hwj huam mov cable rau hauv lub module ib txwm.**
Txuas cov hlau dub (tsis zoo davhlau ya nyob twg) ntawm lub module fais fab cable rov qab mus rau qhov tsis zoo tso zis davhlau ya nyob twg ntawm LED fais fab mov.
Kev Ntsuas Kev Nyeem Ntawv: Tom qab ntsaws rau hauv lub qhov hluav taws xob input thiab tig rau ntawm LED zaub, tam sim no ntawm ib qho module yuav hloov pauv nyob ntawm cov ntsiab lus tau ua si. Nias lub pob xeem ntawm daim npav tswj kom hloov lub xeev lub vijtsam thiab sau cov ntaub ntawv tam sim no nyob rau hauv ntau lub xeev. Piv txwv li:
Qhov tam sim no siab tshaj plaws thaum "tag nrho cov dawb," kwv yees li 5.8A.
Tam sim no yog 3.3A hauv ob lub xeev liab thiab ntsuab.
Tam sim no yog 2.0A hauv lub xeev xiav.
Thaum hloov rov qab mus rau qhov kev ua si ib txwm muaj, qhov tam sim no hloov pauv ntawm 1 thiab 2A.
Xam cov naj npawb ntawm cov modules uas ib qho kev hloov hluav taws xob tuaj yeem siv tau.
Txiav txim siab lub zog zoo ntawm cov khoom siv hluav taws xob: Siv cov khoom siv 200W hloov hluav taws xob ua piv txwv, cov chaw tsim khoom muab cov ntsiab lus hauv qab no: "tso tawm 5V 40A," "kev hloov pauv tau zoo 88%. Xam lub zog siv tau los ntawm LED hloov hluav taws xob siv cov qauv:
$P = 88% × 200W = 176W$
Xam qhov siab tshaj plaws kev siv hluav taws xob ntawm ib qho module: Raws li tus qauv $P=UI$, muab lub module khiav hauj lwm voltage $U=5V$ thiab qhov siab tshaj plaws tam sim no $I=5.8A$ nyob rau hauv "tag nrho cov dawb", lub siab tshaj plaws zog noj ntawm ib tug LED module yog:
$P_1=UI=5V × 5.8A=29W$
Xam cov naj npawb ntawm cov modules uas tuaj yeem tsav tau: Faib lub zog zoo ntawm cov khoom siv hluav taws xob los ntawm kev siv lub zog siab tshaj plaws ntawm ib qho modules kom tau txais cov naj npawb ntawm cov modules uas ib leeg LED hloov hluav taws xob tuaj yeem tsav:
$n = P/P_1 = 176W/29W ≈ 6.069$
Txij li tus naj npawb ntawm cov modules yuav tsum yog ib tug lej, LED fais fab mov yuav tsis overloaded yog tias nws tsav tsis ntau tshaj 6 LED modules. Lub peev xwm thauj khoom suav raws li qhov siab tshaj plaws tam sim no yog qhov muaj peev xwm thauj khoom nyab xeeb. Thaum lub sijhawm ua haujlwm ib txwm muaj, qhov tam sim no feem ntau tsuas yog 1/3 txog 1/2 ntawm qhov siab tshaj plaws tam sim no, tab sis kom muaj kev nyab xeeb thiab ruaj khov lub zog siv hluav taws xob, qhov siab tshaj plaws tam sim no yog siv rau kev suav.
Xam tus naj npawb ntawm Hloov Cov Khoom Siv Hluav Taws Xob yuav tsum tau ua rau lub vijtsam LED zaub
Txiav txim siab tag nrho cov zaub modules: suav pes tsawg LED modules yog spliced ua ke los tsim ib qho loj LED zaub screen.
Xam cov naj npawb ntawm cov khoom siv fais fab: Faib tag nrho cov khoom siv los ntawm kev nyab xeeb lub peev xwm ntawm ib lub zog hluav taws xob kom tau txais cov khoom siv hluav taws xob LED siv rau ib qho screen LED. Piv txwv li, yog tias lub vijtsam npo tau sib txuas ua ke los ntawm 100 LED modules, thiab ib lub zog hluav taws xob tuaj yeem txhawb nqa 6 modules, ces tus naj npawb ntawm cov khoom siv fais fab yog:
$100 ÷ 6 ≈ 16.67$, sib npaug mus txog 17.
