Dab tsi yog qhov tam sim no LED tsav tsheb thiab qhov hluav taws xob tsis tu ncua LED tsav tsheb?

LED tsis tu ncua tam sim no fais fab mov thiab qhov hluav taws xob tsis tu ncua yog dab tsi?
LED teeb pom kev zoo cov khoom siv hluav taws xob tuaj yeem muab faib ua ob pawg loj raws li txoj kev tsav tsheb. Lub zog hluav taws xob tsis tu ncua thiab qhov hluav taws xob tsis tu ncua hluav taws xob. Lub thiaj li hu ua qhov tam sim no / tsis tu ncua voltage txhais tau hais tias cov zis tam sim no / qhov hluav taws xob tseem nyob tsis tu ncua nyob rau hauv ib qho chaw.
Tus tsav tsheb tam sim no tsis tu ncuaCircuit Court tso zis tam sim no tsis tu ncua, thaum qhov tso zis DC voltage sib txawv nrog qhov loj ntawm cov load kuj nyob rau hauv ib tug tej yam, qhov me me load kuj, qhov qis cov zis voltage, qhov loj dua load kuj, qhov ntau dua cov zis voltage.
Flos yog tus tsav tsheb voltage, thaum txiav txim siab ntau yam tsis sib xws hauv qhov hluav taws xob stabilizing Circuit Court, qhov tso zis hluav taws xob yog tsau, tab sis cov zis tam sim no hloov nrog qhov nce lossis txo cov load.
Qhov chaw ntawm" tas mus li" yog nyob rau hauv ib tug tej yam. Rau" tas li tam sim no" nws txhais tau hais tias cov zis voltage yuav tsum nyob rau hauv ib tug tej yam ntau yam, thiab rau" tas li voltage" nws txhais tau hais tias cov zis tam sim no yuav tsum nyob rau hauv ib tug tej yam. Tshaj qhov no," tas mus li" tswj tsis tau. Yog li ntawd, qhov chaw qhov hluav taws xob tas li yuav teeb tsa cov ntaub ntawv tso tawm tam sim no (qhov tso zis ntau tshaj) tsis muaj. Qhov tseeb, tsis muaj ib yam dab tsi li "s tas li" hauv lub ntiaj teb hluav taws xob. Tag nrho cov khoom siv hluav taws xob muaj qhov taw qhia ntawm kev tswj kev thauj khoom. Siv qhov hluav taws xob tas li (voltage) qhov chaw ua piv txwv: raws li koj qhov kev thauj khoom nce, cov zis hluav taws xob yuav tsum poob.
