Lub teeb pom kev nkag mus ntawm LED teeb yuav nce ntxiv, uas ua rau ntau txhiab tus Suav LED teeb lub tuam txhab zoo siab rau kev hloov pauv ntawm lub teeb ntsuab ntsuab - vim tias lub lag luam loj loj LED tab tom yuav qhib, thiab lub sijhawm no nws yog Suav tuam txhab uas ua lub luag haujlwm tseem ceeb. Txawm li cas los xij, nws yuav tsum pom tias txhawm rau kom nrov LED teeb, tsis yog tus nqi yuav tsum tau txo qis, tab sis tseem yuav tsum tau daws cov teeb meem ntawm kev siv hluav taws xob thiab kev ntseeg siab?
1. Tsis txhob siv cov khoom siv hluav taws xob bipolar. Txij li cov khoom siv hluav taws xob bipolar pheej yig dua li MOSFETs, feem ntau yog kwv yees li 2 xees ib thooj, qee cov neeg tsim qauv siv cov khoom siv hluav taws xob bipolar txhawm rau txo tus nqi ntawm LED tsav tsheb. Qhov no yuav cuam tshuam rau kev ntseeg siab ntawm lub Circuit Court, vim tias qhov kub ntawm LED tsav Circuit Court board nce, kev ua haujlwm zoo ntawm cov cuab yeej bipolar yuav sai sai, uas yuav ua rau lub cuab yeej ua tsis tiav thaum kub nce thiab cuam tshuam rau kev ntseeg tau ntawm lub teeb LED. Yog Txoj kev yog siv cov hlau-oxide-semiconductor teb cov nyhuv transistor, thiab nws lub neej kev pab cuam ntev npaum li cas ntawm cov khoom siv bipolar.
2. Lub MOSFET nrog ib tug withstand voltage ntawm 600V yog kuj pheej yig. Ntau tus neeg xav tias qhov hluav taws xob input ntawm LED teeb feem ntau yog 220V, yog li qhov kev tiv thaiv hluav taws xob ntawm 600V yog txaus, tab sis nyob rau hauv ntau zaus qhov hluav taws xob Circuit Court yuav ncav cuag 340V. Thaum muaj qhov nce siab, 600V Nws yog qhov yooj yim kom tawg, yog li cuam tshuam rau lub neej ntawm LED teeb, nws yog qhov zoo tshaj plaws los siv cov hlau oxide semi-field effect transistors nrog lub zog ntawm ntau tshaj 700V.
3. Electrolytic capacitor yuav muaj hnub nyoog. Tsis tas li ntawd, qhov kub ntawm LED teeb yog qhov nyuaj heev los tswj, yog li lub neej ntawm electrolytic capacitors yuav inevitably txo qis, yog li cuam tshuam rau lub neej ntawm LED teeb. Nyob rau hauv no hais txog, tus lwm thawj ntawm kev lag luam ntawm American Power Integration Company ntseeg hais tias nyob rau hauv LED tsav Circuit Court Input ib feem yuav txiav txim siab tsis muaj electrolytic capacitors. Qhov tseeb, kev siv PI lub zog nti uas tuaj yeem paub qhov dimming tuaj yeem txuag tau cov khoom siv hluav taws xob electrolytic. PI's ib-theem PFC / qhov tsim tam sim no tso cai rau cov neeg tsim qauv kom txuag tau lub peev xwm loj. Nyob rau hauv qhov tso zis hluav taws xob, koj tuaj yeem siv high voltage ceramic capacitors es tsis txhob electrolytic capacitors los txhim kho kev ntseeg tau. "Qee tus neeg siv lub 400V electrolytic capacitor rau cov zis thaum tsim ib lub voj voog ob-theem, uas yuav cuam tshuam rau kev ntseeg siab ntawm Circuit Court. Nws raug nquahu kom siv Ceramic capacitor rau ib-theem circuits yog qhov zoo. Rau cov ntawv thov kev lag luam uas tsawg dua Kev txhawj xeeb nrog kev dimming, kub ib puag ncig, thiab kev ntseeg siab, electrolytic capacitors tsis pom zoo rau kev tsim. "
4. Yog hais tias lub zog ntawm lub teeb LED tsim tsis yog siab heev, nws raug nquahu kom siv cov khoom siv tsav tsheb LED ua ke nrog MOSFET, vim qhov zoo ntawm qhov no yog qhov kev tiv thaiv ntawm kev sib xyaw MOSFET tsawg dua, thiab cov cua sov tsim tawm. yog tsawg tshaj qhov discrete ib. Tsis tas li ntawd, kev sib xyaw MOSFET yog tus tswj thiab FET ua ke. Feem ntau, nws muaj ib qho overheat shutdown muaj nuj nqi. Thaum lub MOSFET yog overheated, nws yuav cia li kaw lub Circuit Court los tiv thaiv lub LED teeb. Qhov no yog ib qho tseem ceeb heev rau LED teeb, vim hais tias LED teeb yog feem ntau me me thiab nyuaj rau cua txias. "Qee zaum nws tshwm sim tias LED hlawv thiab ua rau tib neeg mob vim muaj cua sov.
5. Txais kev tsim qauv ntawm "PFC (lub hwj chim kho kom haum) ntxiv rau kev sib cais DC / DC converter", qhov kev tsim no yuav txo qhov kev ua haujlwm ntawm lub voj voog. Piv txwv li, yog tias qhov ua tau zoo ntawm PFC yog 95 feem pua thiab qhov ua tau zoo ntawm DC / DC seem yog 88 feem pua, qhov ua tau zoo ntawm tag nrho cov Circuit Court poob mus rau 83.6 feem pua! "PI's LinkSwitch-PH ntaus ntawv sib koom ua ke PFC / CC maub los, 725V MOSFET thiab MOSFET tsav tsheb rau hauv ib pob, ua kom muaj txiaj ntsig ntawm kev tsav tsheb mus rau 87 feem pua! 25 cov khoom siv hauv cov qauv kev sib cais flyback! Cov khoom tshem tawm suav nrog cov hluav taws xob hluav taws xob hluav taws xob hluav taws xob hluav taws xob thiab optocouplers. LED ob-theem architecture yog tsim nyog rau qhov yuav tsum tau siv ib tug thib ob qhov tam sim no tsav Circuit Court rau lub PFC tsav lub LED tas li Streaming legacy drives. Cov qauv tsim no tau dhau los thiab tsis raug nqi ntxiv lawm, yog li kev tsim ib theem zoo dua nyob rau hauv feem ntau.
