LED teeb pom kev zoo tau dhau los ua cov thev naus laus zis tseem ceeb.LED teeb nyem, cov teeb liab tsheb, thiab teeb taws teeb nyob txhua qhov chaw, thiab lub teb chaws tau txhawb nqa kev siv cov teeb ci LED los hloov cov teeb pom kev zoo thiab cov teeb fluorescent hauv thaj chaw, kev lag luam, thiab kev lag luam kev siv hluav taws xob los ntawm lub zog loj.Txawm li cas los xij, yog tias LED teeb pom kev zoo yuav hloov cov qhov muag teev ua lub hauv paus ntawm lub teeb pom kev zoo, thyristor dimming LED thev naus laus zis yuav yog qhov tseem ceeb cuam tshuam.
Rau cov teeb pom kev zoo, dimming yog cov txheej txheem tseem ceeb heev.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 rau kev loj hlob sai ntawm LED daim ntawv thov kev lag luam, daim ntawv thov Scope ntawm LED cov khoom tseem yuav loj hlob ntxiv.LED cov khoomyuav tsum ua kom tau raws li qhov xav tau ntawm qhov sib txawv daim ntawv thov ib puag ncig, yog li ntawd, LED brightness tswj kev ua haujlwm kuj tseem tsim nyog.
Txawm tias tsis dimmingLED teebtseem muaj lawv lub khw.Txawm li cas los xij, 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 ua kom muaj teeb pom kev zoo dimmable, nws lub zog yuav tsum muaj peev xwm tso tawm lub kaum sab xis ntawm lub thyristor maub los, txhawm rau txhawm rau kho qhov tsis tu ncua tam sim no ntws mus rau LED.Nws yog qhov nyuaj heev kom ua tiav qhov no thaum tswj kev ua haujlwm ntawm lub dimmer, uas feem ntau ua rau kev ua haujlwm tsis zoo.Flashing 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 tshawb nrhiav cov cuab yeej zoo LED dimming thiab cov kev daws teeb meem.Marvell, uas yog lub chaw tsim khoom lag luam thoob ntiaj teb semiconductor, tau pib nws txoj kev daws teeb meem rau LED dimming.Cov tswv yim no yog raws li 88EM8183 thiab yog tsim los rau offline dimmable LED teeb pom kev zoo daim ntawv thov, ua tiav qhov tsawg kawg nkaus qhov tob dimming ntawm 1%.Vim nws qhov tshwj xeeb tseem ceeb ntawm kev tswj hwm tam sim no, 88EM8183 tuaj yeem ua tiav cov khoom tsim tawm tam sim no nruj heev rau ntau yam ntawm AC inputs.
