Yuav ua li cas txheeb xyuas LED teeb sawb nrog multimeter
kauj ruam:
1. Ua ntej, tig qhov hloov pauv ntawm tus pointer multimeter mus rau Rx10 kiloohm ntau yam;
2. Ntxig tus cwj mem ntsuas dub rau hauv qhov tsis zoo ntawm lub qhov (socket), thiab lub ntsuas liab liab ntsaws rau hauv lub qhov (socket) qhov zoo;
3. Siv cov kev sim dub coj los txuas rau tus ncej zoo ntawm ib lub teeb ci LED hlaws, thiab ib qho kev sim liab ua rau txuas mus rau qhov tsis zoo ntawm ib lub teeb LED hlaws;
4. Yog tias lub teeb hlaws tau teeb, nws yog qhov qub. Yog tias nws tsis taws, nws txhais tau hais tias lub teeb hlaws yog qhov pib tawg.
Yuav ua li cas xam cov hluav taws xob noj ntawm LED teeb strips
Lub zog noj ntawm LED sawb tuaj yeem xam los ntawm cov qauv hauv qab no: LED sawb lub zog * siv sijhawm=lub zog noj ntawm LED sawb.
Rau cov kab LED dav dav, lub zog ib meter ntawm 0603 yog 1.5W, lub zog ib meter ntawm 1210 LED strips yog 4.8W, thiab lub zog ib meter ntawm 5050 LED strips yog 7.2W.
Muab xam raws li 5050LED lub teeb sawb nrog lub zog siab tshaj plaws, nrog 7.2W ib meter thiab 8 teev ib hnub, tom qab ntawd:
Lub zog noj txhua hnub yog 7.2W * 8h=57.6wh
Lub zog noj txhua hli yog 57.6wh * 30=1728wh (1.728kwh, uas yog, 1.728 kWh)
Kev siv hluav taws xob txhua xyoo yog 1728wh * 12=20736wh (20.736kwh, uas yog, 20.736 kWh)
Yog tias muaj ntau lub teeb ci LED siv, kev siv hluav taws xob txhua hnub, txhua hli thiab txhua xyoo ntawm LED lub teeb strips tuaj yeem tau los ntawm kev sib npaug ntawm qhov ntsuas no los ntawm cov meters.
Qhov tseeb, hauv tsev neeg, qhov kev siv txhua hnub tsis yog 8 teev. Txawm hais tias nws raug xam raws li 8 teev, tus nqi siv hluav taws xob yuav luag tsis pom zoo. Yog li ntawd, txhua tus tuaj yeem siv nrog kev ntseeg siab.
