LED teeb pom kev zoo tau dhau los ua cov thev naus laus zis tseem ceeb.LED teeb nyem, teeb pom kev thiab teeb pom kev nyob txhua qhov chaw.Lub teb chaws tab tom txhawb kev hloov cov teeb pom kev zoo thiab cov teeb fluorescent hauv thaj chaw, kev lag luam thiab kev lag luam uas siv los ntawm lub zog loj nrog cov teeb ci LED.Txawm li cas los xij, yog tias cov teeb pom kev zoo ntawm LED yog los hloov cov teeb incandescent thiab dhau los ua lub cev tseem ceeb ntawm lub teeb pom kev zoo, silicon tswj dimming LED thev naus laus zis yuav yog qhov tseem ceeb.

Dimming yog ib qho tseem ceeb heev rau lub teeb qhov chaw.Vim tias nws tuaj yeem tsis tsuas yog muab lub teeb pom kev zoo ib puag ncig, tab sis kuj ua tiav kev txuag hluav taws xob thiab txo qis emission.Nrog kev loj hlob sai ntawm LED daim ntawv thov kev lag luam, daim ntawv thov Scope ntawmLED cov khoomtseem yuav loj hlob mus ntxiv.LED cov khoom lag luam yuav tsum ua kom tau raws li qhov xav tau ntawm qhov sib txawv daim ntawv thov ib puag ncig, yog li LED qhov ci ci tswj kev ua haujlwm tseem tsim nyog.

Txawm tias covLED teebtsis dimming tseem muaj nws lub khw.Tab sis daim ntawv thov ntawm LED dimming thev naus laus zis tuaj yeem tsis tsuas yog txhim kho qhov sib piv, tab sis kuj txo qis kev siv hluav taws xob.Yog li ntawd, txoj kev loj hlob ntawm LED dimming tshuab yog ib qho inevitable qauv.Yog tias LED xav paub qhov dimming, nws lub hwj chim yuav tsum muaj peev xwm tso tawm qhov sib txawv ntawm lub kaum sab xis ntawm silicon tswj tswj, txhawm rau kho qhov tam sim no ntws mus rau LED hauv ib qho kev taw qhia.Nws yog qhov nyuaj heev los ua qhov no thaum tswj kev ua haujlwm ntawm lub dimmer, uas feem ntau ua rau kev ua haujlwm tsis zoo.Blinking thiab teeb pom kev tsis sib xws tshwm sim.

Tau ntsib cov teeb meem ntawm LED dimming, cov tuam txhab loj hauv kev lag luam tau maj mam kawm cov cuab yeej zoo LED dimming thiab cov kev daws teeb meem.Marvell, raws li lub ntiaj teb ua lag luam semiconductor, tau pib nws cov kev daws teeb meem rau LED dimming.Cov tswv yim no yog ua raws li 88EM8183 thiab yog tsim los rau offline dimmable LED teeb pom kev zoo, uas tuaj yeem ua tiav qhov tsawg kawg nkaus ntawm 1% tob dimming.Vim tias 88EM8183 siv lub cim tseem ceeb ntawm kev tswj hwm tam sim no, nws tuaj yeem ua tiav cov zis tawm tam sim no nruj heev hauv qhov dav AC cov tswv yim.
