Txoj kev suav ntawm kev hloov hluav taws xob rau LED zaub
Nqe Lus Nug 1: Lub zog ntawm PH10 thiab PH12.5 semi-tawm sab nrauv chav tsev boards: Yog hais tias tus naj npawb ntawm LED cov ntsiab lus (teeb) ntawm ob lub qauv yog tib yam, lawv lub hwj chim yog theoretically tib yam, tab sis qhov loj ntawm 12.5 chav tsev board yog loj dua li ntawm PH10 unit Lub rooj tsavxwm loj!
Txoj kev suav fais fab: 0.02A (tam sim no) * 5V (voltage) * 32 * 16 (tus naj npawb ntawm LED teeb) * 1/4 (tus naj npawb ntawm scans)=12.8W (lub zog ntawm chav tsev pawg thawj coj saib)
Nqe Lus Nug 2: 12 P12.5 liab ib nrab chav tsev sab nraum zoov xav tau 5V40A hloov hluav taws xob, thiab lub zog ntawm 12 32*16-point PH12.5 unit boards: 12 * 12.{{13} }.6 W. A 5V40A200W hloov hluav taws xob tuaj yeem ua tau raws li qhov xav tau ua haujlwm ntawm 12 PH12.5 chav tsev sab nrauv sab nrauv!
LED zaub hloov fais fab mov ib txheej ntawm cov xov hlau nrog ntau lub rooj tsavxwm
Ib qho dav dav 200W fais fab mov tuaj yeem nqa tau 16-20 boards. Yog tias koj tsuas muaj modules, koj tuaj yeem nqa nws li no. Tab sis yog tias koj hais tias ib qho nrog daim npav system tsis yog ntau, koj yuav tsum tawm qee qhov paj rau daim npav system. , vim hais tias daim npav system tsis xav tau tam sim no ntau, tab sis muaj qhov xav tau ntau dua rau qhov voltage, nws raug pom zoo tias daim npav system nrog 14 ceev modules feem ntau. Tau kawg, thaum koj lub vijtsam zaub ua haujlwm ib txwm ua, qhov ntau dua qhov voltage poob ntawm koj cov khoom siv hluav taws xob ntau, qhov kev pab cuam lub neej ntawm koj lub hwj chim poob qis dua. Ib lub teeb ntawm koj lub module raug xam raws li 20mA, thiab ib qho module yog 32 * 16 * 0.02 / 8 =1.28A ntxiv rau 0.5 noj los ntawm lub rooj tsavxwm nws tus kheej yog 1.78A. Koj tsuas tuaj yeem siv 85 feem pua ntawm cov khoom siv hluav taws xob ntsuas, uas yog, 170W muab faib los ntawm 5V yog sib npaug rau 36A faib los ntawm 1.78, uas yog kwv yees li sib npaug rau 20 qhov ceev modules, uas yog tus nqi siab tshaj plaws. Feem ntau, nws txaus los nqa 16 daim. Koj txoj kab 1.5mm² tsuas yog nqa tau 12A feem ntau, uas yog hais, koj cov kab tuaj yeem nqa mus txog 6 daim. Koj tuaj yeem siv 2.5mm² kab kom dhau 22A. Muab xam rau koj tus kheej, txawm hais tias tam sim no khiav ceev, tab sis koj kuj yuav tsum tau ua raws li qhov nruab nrab faib, ua ntej mus rau qhov tseeb, thiab tom qab ntawd mus rau qhov deb, koj txoj kab hluav taws xob tsis tuaj yeem ntev dhau, lossis yuav muaj qhov sib txawv. voltage poob los yog tshwm ci ntsa iab nyob ze ntawm lub hwj chim mov, deb ntawm nws Cov sawv daws yuav tsaus dua. Cia peb saib qhov xwm txheej tiag tiag.
