Txhua tus tsav tsheb yog tam sim no tsis tu ncua (CC) lossis hluav taws xob tas li (CV), lossis ob qho tib si. Nov yog ib qho ntawm thawj yam koj xav xav txog nyob rau hauv koj txoj kev txiav txim siab cov txheej txheem. Qhov kev txiav txim siab no yuav txiav txim siab los ntawm LED lossis module koj yuav tau siv zog, cov ntaub ntawv uas tuaj yeem pom ntawm LED cov ntaub ntawv cov ntaub ntawv.
SAWV DAWS TAU TSEG?
Cov hluav taws xob tsis tu ncua (CC) tsav tsheb LED kom muaj hluav taws xob tsis tu ncua thoob plaws hluav taws xob los ntawm muaj hluav taws xob tsis hloov pauv. Cov tsav tsheb CC feem ntau yog qhov kev xaiv nrov tshaj plaws rau LED daim ntaub ntawv. Cov tsav tsheb CC LED tuaj yeem siv rau lub teeb ci ib leeg lossis ib txoj saw ntawm LEDs hauv kab xwm. Ib hom txhais tau hais tias cov LEDs txhua tus tau sib dhos ua ke hauv kab, rau qhov tam sim no ntws los ntawm txhua qhov. Qhov tsis zoo yog tias, yog tias lub Circuit Court tawg, tsis muaj ib qho ntawm koj LED yuav ua haujlwm. Txawm li cas los xij lawv feem ntau muaj kev tswj hwm zoo dua qub thiab muaj lub zog zoo dua li cov hluav taws xob tas li.
VOLTAGE YOG DAB TSI?
Qhov hluav taws xob tas li (CV) LED tsav tsheb yog cov khoom siv fais fab. Lawv muaj lub teeb hluav taws xob uas lawv xa mus rau hluav taws xob Circuit Court. Koj yuav siv CV LED tsav tsheb los khiav ntau LEDs hauv parallel, piv txwv li LED strips. CV cov khoom siv fais fab tuaj yeem siv nrog LED coj uas muaj qhov txwv tam sim no, uas feem ntau ua. Qhov tso zis hluav taws xob yuav tsum ua kom tau raws li qhov ntsuas qhov xav tau ntawm tag nrho cov hlua LED.
CV tsav tsheb kuj tseem siv tau rau lub teeb ci LED uas muaj tsav tsheb IC ntawm lub nkoj.
THAUM KUV YUAV SIV CV LOS YOG CC?
Feem ntau ntawm Tauras cov khoom yog qhov hluav taws xob tas li. Nws haum rau coj sawb teeb, cim teeb pom kev zoo, teeb pom kev zoo iav, Theem teeb pom kev zoo, kos duab lub teeb pom kev zoo, txoj kev teeb pom kev zoo thiab lwm yam.
