LED cov khoom siv hluav taws xob yog ib hom kev tswj xyuas tam sim no, LED tsav tsheb yog qhov ua tau zoo ntawm lub zog ntawm LED, uas yog, cov khoom siv hluav taws xob uas hloov AC lub zog mus rau qhov tam sim no lossis qhov tsis tu ncua ntawm DC lub zog.Tsis zoo li cov teeb pom kev zoo tib yam, LED cov khoom siv hluav taws xob tuaj yeem txuas ncaj qha rau 220V AC mains.LEDs muaj qhov yuav luag hnyav rau kev tsav tsheb, thiab lawv qhov kev ua haujlwm voltage feem ntau yog 2 ~ 3V DC voltage, thiab kev hloov pauv nyuaj yuav tsum tau tsim.LED teeb rau ntau lub hom phiaj yuav tsum tau nruab nrog lub zog sib txawv adapters.

Cov khoom siv LED muaj cov kev xav tau siab heev rau kev hloov pauv kev ua haujlwm, lub zog zoo, qhov tseeb qhov tseeb, lub neej muaj zog, thiab hluav taws xob sib raug zoo ntawm LED tsav lub zog.Lub zog tsav zoo yuav tsum coj cov yam ntxwv no rau hauv kev xav, vim hais tias lub zog tsav yog nyob rau hauv tag nrho LED teeb.Lub luag haujlwm tseem ceeb npaum li tib neeg lub siab.Lub luag haujlwm tseem ceeb ntawm tus tsav tsheb LED yog hloov AC voltage mus rau qhov tam sim no DC fais fab mov, thiab tib lub sijhawm ua kom tiav qhov sib txuam nrog LED voltage thiab tam sim no.Lwm txoj haujlwm ntawm tus tsav tsheb LED yog ua kom lub sijhawm thauj khoom tam sim no ntawm LED tswj ntawm qib tsim ua ntej raws li kev cuam tshuam ntawm ntau yam.

Muaj cov xwm txheej rau LED hluav taws xob tso tawm kom pom lub teeb.Lub zog hluav taws xob rau pem hauv ntej yog siv rau ob qho kawg ntawm PN hlws ris, yog li ntawd PN hlws ris nws tus kheej tsim ib theem zog (qhov tseeb yog ib theem ntawm lub zog), thiab cov hluav taws xob dhia ntawm lub zog no thiab tsim cov photons kom tawm lub teeb.Yog li, qhov hluav taws xob siv thoob plaws PN kev sib tshuam yuav tsum tau tsav lub LED kom tawm lub teeb.Tsis tas li ntawd, vim hais tias LEDs yog cov yam ntxwv-rhiab cov khoom siv semiconductor nrog cov yam ntxwv kub tsis zoo, lawv yuav tsum tau ruaj khov thiab tiv thaiv thaum lub sijhawm thov, yog li ua rau lub tswv yim ntawm LED "tsav".

Txhua tus neeg uas tau ntsib nrog LEDs paub tias cov yam ntxwv ntawm volt-ampere ntawm LEDs yog qhov hnyav heev (qhov hluav taws xob rau pem hauv ntej yog me me), thiab nws nyuaj rau muab lub zog rau LED.Nws tsis tuaj yeem siv ncaj qha los ntawm qhov chaw hluav taws xob zoo li cov teeb pom kev zoo tib yam.Txwv tsis pub, qhov voltage Nrog me ntsis kev hloov pauv, tam sim no yuav nce mus rau qhov taw tes uas LED yuav raug hlawv.Txhawm rau txhim kho qhov ua haujlwm tam sim no ntawm LED thiab xyuas kom meej tias LED tuaj yeem ua haujlwm ib txwm muaj thiab ntseeg tau, ntau yam LED tsav circuits tau tshwm sim.
