Dab tsi yog qhov kev daws teeb meem rau LED luminaire strobe
Tam sim no, yog tias ntau thiab ntau siv LED teeb pom kev zoo siv cov khoom siv hluav taws xob DC tas li, nws yog qhov ua tau kom ua tiav qhov teeb pom kev tas li yam tsis muaj flicker. Tab sis qhov tseeb, vim tsis muaj cov qauv kev lag luam thiab kev sib tw ua lag luam hnyav thiab tsis sib haum xeeb, kev ua lag luam raug dej nyab nrog cov teeb pom kev zoo LED, tshwj xeeb tshaj yog nyob rau sab hauv tsev tsis muaj zog LED teeb, uas kuj muaj teeb meem stroboscopic. Txhawm rau kom tau txais qhov chaw ntshiab tam sim no, LED tsav lub zog hluav taws xob yog tus yuam sij kom ntseeg tau tias LED teeb pom kev zoo tsis flicker. Tam sim no, LED fais fab mov tuaj yeem ua tau raws li qhov yuav tsum tau ua kom tsis muaj flicker. Muaj kwv yees li ob txoj kev:
Ua ntej, nce cov zis electrolytic capacitor: Txoj kev no tuaj yeem nqus tau ib feem ntawm AC ripple, tab sis cov kev sim cuam tshuam tau pom tias thaum lub ripple raug tswj nyob rau hauv qee qhov ntau (10%), nws nyuaj rau txo nws, tshwj tsis yog cov electrolysis. yog nce. Tus nqi ntawm capacitors tsis tuaj yeem tshem tawm tag nrho lwm yam.
Thib ob, txais yuav ib qho kev daws teeb meem ob theem: uas yog, raws li cov khoom siv hluav taws xob uas twb muaj lawm, ntxiv rau thawj theem DC fais fab mov tuaj yeem tshem tawm tag nrho cov kev cuam tshuam ntawm AC ripple, thiab cov hluav taws xob tsis zoo yuav ua tau raws li cov qauv ntawv pov thawj. Txawm li cas los xij, tus nqi ntawm qhov kev zov me nyuam tau nce mus rau qee qhov, thiab nws yuav tsum tau ntxiv ntau lub zog tswj cov chips thiab qee cov khoom siv hluav taws xob.
