Tej zaum koj yuav xav tsis thoob, LED tsav tsheb yog dab tsi thiab koj puas xav tau lawv tiag tiag rau koj lub teeb? LED tsav tsheb yog ib qho khoom siv hluav taws xob uas kho lub zog rau LED lossis pab pawg ntawm LEDs. Koj yuav tsum muaj nws nyob rau hauv koj lub LED Circuit Court vim nws tuaj yeem ua rau lub cev tsis ua haujlwm yog tias koj ua haujlwm tsis muaj ib qho.
Kev siv cov cuab yeej no yog qhov tseem ceeb hauv kev tiv thaiv kev puas tsuaj rau koj cov LEDs txij li qhov hluav taws xob rau pem hauv ntej (ntau npaum li cas ntawm cov volts lub LED yuav tsum tau ua hluav taws xob tam sim no thiab teeb ci) ntawm lub zog hluav taws xob LED muaj qhov kub thiab txias. Raws li qhov kub thiab txias, qhov hluav taws xob pem hauv ntej poob qis, ua rau lub LED kom tau txais lub zog ntau dua. Yog tias qhov no txuas ntxiv mus, LED yuav kub dua thiab kos tam sim no kom txog thaum nws hlawv nws tus kheej tawm.
Tus tsav tsheb LED yog lub zog ntawm tus kheej nrog cov khoom siv zoo sib xws li LED. Qhov no pab nres koj lub teeb kom tsis txhob kub hnyiab vim tus tsav tsheb LED them nyiaj rau qhov kev hloov pauv hauv qhov hluav taws xob rau pem hauv ntej, xa lub zog tsis tu ncua.
Ua ntej koj tawm mus thiab yuav tus tsav tsheb LED rau koj lub teeb, nug cov lus nug hauv qab no:
Dab tsi yog hom LED uas koj siv thiab muaj pes tsawg?
Koj puas xav tau tus tsav tsheb tsis tu ncua LED, lossis koj yuav tsum tau txais tus tsav tsheb tam sim no tsis tu ncua?
Hom fais fab twg koj siv (AC, DC, roj teeb, thiab lwm yam)?
Koj puas muaj chaw txwv?
Lub hom phiaj tseem ceeb ntawm koj qhov teeb tsa yuav yog dab tsi?
Puas muaj qhov xav tau rau lwm yam tshwj xeeb (dimming, pulsing, thiab lwm yam)?
Ua ntej txhua yam, koj yuav tsum paub tias muaj ob hom LED tsav tsheb, qis-voltage DC input zog (5-36VDC) thiab high voltage AC input zog (90-277VAC). Txawm li cas los xij, ntawm ob, feem ntau siv yog cov tsav tsheb tsis tshua muaj hluav taws xob DC vim tias lawv ua haujlwm tau zoo thiab txhim khu kev qha. Txawm hais tias koj lub tswv yim yog high-voltage AC, ntxiv ib qho kev hloov pauv ntxiv ua rau koj siv tus tsav tsheb DC.
