Dab tsi yog yam uas cuam tshuam rau lub neej ntawm LED fais fab mov
1. Qhov cuam tshuam ntawm kev siv ib puag ncig: cov av noo ib puag ncig, qhov kub thiab txias ib puag ncig, plua plav ib puag ncig, muaj zog sib nqus ib puag ncig, kev co ib puag ncig
2. Kev cuam tshuam ntawm lub teeb pom kev kub ib puag ncig: qhov kub ntawm lub teeb pom kev zoo yog tsawg dua 65 degrees, lub plhaub sab nraud ntawm lub teeb pom kev zoo yog tsawg dua 75 degrees, thiab lub zog hluav taws xob kub yog tsawg dua 60 degrees.
3. Qhov cuam tshuam ntawm daim phiaj hluav taws xob: tsis ruaj tsis khov voltage input los ntawm daim phiaj hluav taws xob tuaj yeem muaj kev cuam tshuam rau cov khoom siv hluav taws xob LED, yog li cuam tshuam rau lub neej kev pab cuam ntawm LED tsav tsheb.
4. Qhov cuam tshuam ntawm rwb thaiv tsev thiab kev teeb tsa: Kev teeb tsa kom zoo thiab kev rwb thaiv tsev zoo ntawm cov khoom yuav txhim khu kev siv ntawm LED fais fab mov.
5. Qhov cuam tshuam ntawm electrolytic capacitors: Lub sealing ib feem ntawm electrolytic capacitors yuav xau vaporized electrolyte, uas yuav ceev nrog qhov kub thiab txias. Nws yog feem ntau ntseeg tias rau txhua txhua 10 degree nce nyob rau hauv qhov kub thiab txias, tus nqi xau yuav ob npaug.
Yog li, nws tuaj yeem hais tias electrolytic capacitors txiav txim siab lub neej ntawm cov khoom siv hluav taws xob.
Yog hais tias qhov kub-kub electrolytic capacitor nrog lub neej ntev ntawm 10000 teev thiab qhov kub ntawm 105 degrees raug xaiv, raws li cov qauv siv feem ntau rau kev kwv yees lub neej ntawm electrolytic capacitors, uas hais tias 'rau txhua 10 degrees txo, lub neej ntev dua ob npaug', ces nws lub neej ua haujlwm yog 20000 teev nyob rau hauv 95 degree ib puag ncig thiab 40000 teev nyob rau hauv 85 degree ib puag ncig.
Lub neej ua haujlwm ntawm LED tsav lub zog yog nyob ntawm lub neej ntawm electrolytic capacitor siv los ntawm lub hwj chim mov, uas nyob rau hauv lem nyob ntawm lub neej ntawm lub capacitor nws tus kheej thiab ua hauj lwm kub.
Lub neej ntev ntawm lub capacitor ntawm qhov kub ntawm 65 degree tsuas tuaj yeem lav txog 80000 teev; Lub neej ntev ntawm lub capacitor ntawm qhov kub ntawm 75 degree tsuas tuaj yeem lav txog 40000 teev; Lub neej ntev ntawm lub capacitor ntawm qhov kub ntawm 85 degree tsuas tuaj yeem lav txog 20000 teev; Lub neej ntev ntawm lub capacitor ntawm qhov kub ntawm 95 degree tsuas tuaj yeem lav txog 10000 teev; Raws li kev suav sau saum toj no, lub neej ntawm electrolytic capacitors yuav raug txiav ib nrab rau txhua 10 degree qhov kub thiab txias.
6. Qhov cuam tshuam ntawm kev hloov pauv ntau zaus: Cov khoom siv hluav taws xob feem ntau yog nruab nrog lub capacitor input rectifier circuits, uas tuaj yeem tsim cov surge tam sim no thaum lub hwj huam mov qhib, ua rau hloov kev sib cuag qaug zog, muaj zog tiv thaiv, thiab teeb meem adsorption. Hauv txoj kev xav, nws ntseeg tau tias thaum lub sijhawm xav tau ntawm lub zog hluav taws xob, qhov hloov pauv yuav qhib thiab tawm kwv yees li 10000 zaug.
7. Qhov cuam tshuam ntawm surge tam sim no tiv thaiv resistors thiab thermal hwj chim resistors: Txhawm rau tiv thaiv cov hluav taws xob tam sim no tsim thaum lub hwj chim qhib, kev tsim hluav taws xob feem ntau siv cov resistors nyob rau hauv parallel nrog SCR thiab lwm yam khoom.
