Yam dab tsi txiav txim siab lub neej ntawm LED fais fab mov?
Lub neej ntawm LED fais fab mov yog cuam tshuam los ntawm ntau yam, feem ntau suav nrog cov hauv qab no:
1. Cov khoom zoo
Electrolytic capacitor: Nws yog ib qho tseem ceeb uas cuam tshuam rau lub neej. Cov electrolyte yog ib qho yooj yim kom qhuav ntawm qhov kub thiab txias, ua rau muaj peev xwm txo qis lossis tsis ua haujlwm.
Cov khoom siv semiconductor (xws li MOS tubes, diodes): Overvoltage, overcurrent lossis kub kub yuav ua rau kev laus.
Cov khoom sib nqus (transformers, inductors): Cov ntaub ntawv tsis zoo lossis kev tsim tsis zoo yuav ua rau cua sov lossis txo qhov ua haujlwm.
2. Kub
Ambient kub: Qhov kub thiab txias ib puag ncig (xws li qhov chaw kaw) yuav ua rau kom muaj kev laus zuj zus. Feem ntau,lub neej yog halved rau txhua txhua 10℃nce.
Lub zog hluav taws xob kub nce: Kev tsim hluav taws xob tsis txaus (xws li tsis muaj lub dab dej kub, cua tsis zoo) yuav ua rau muaj qhov kub thiab txias.
3. Cov xwm txheej thauj khoom
Tus nqi thauj khoom: Ntev- lub sijhawm ua haujlwm puv lossis kev ua haujlwm dhau yuav ua rau lub neej luv.
Load fluctuation: nquag pib thiab nres lossis tam sim no hloov tam sim no tuaj yeem ua rau muaj kev ntxhov siab.
4. Cov tswv yim fais fab zoo
Voltage fluctuation: Cov hluav taws xob ntau dhau tuaj yeem ua rau overvoltage tawg, thaum qhov hluav taws xob tsawg dhau tuaj yeem ua rau lub zog hluav taws xob ua haujlwm hauv lub xeev tsis zoo.
Kev cuam tshuam ntawm daim phiaj: xob laim, surges lossis harmonics tuaj yeem ua rau cov khoom siv lim tawm lossis cov nti tswj.
5. Cov qauv tsim
Topology: Cov txheej txheem sib txawv xws li flyback thiab LLC muaj qhov sib txawv ntawm lub neej.
Derating tsim: Tsim nyog derating ntawm Cheebtsam (xws li capacitor withstand voltage thiab tam sim no margin) tuaj yeem txuas lub neej.
Kev tiv thaiv Circuit Court: Kev ua tiav ntawm overvoltage, overcurrent thiab overheating tiv thaiv ncaj qha cuam tshuam kev ntseeg tau.
6. Ib puag ncig ua haujlwm
Humidity thiab plua plav: Ib puag ncig ntub lossis plua plav tuaj yeem ua rau luv luv lossis xeb.
Kev co thiab kev poob siab: Kev ntxhov siab hauv tshuab yuav ua rau tawg ntawm cov pob qij txha los yog xoob ntawm cov khoom.
7. Hom tsav tsheb
Tsis tu ncua tam sim no vs. qhov voltage tsis tu ncua: LEDs feem ntau yuav tsum tau tsav tam sim no, thiab cov khoom siv hluav taws xob tsis tu ncua yog qhov ua rau tsis muaj kev tswj hwm tam sim no vim muaj kev hloov pauv hauv LED cov yam ntxwv.
Dimming hom: PWM dimming yuav ua rau muaj kev hloov pauv ntau dua li analog dimming.
Cov lus qhia rau kev ncua lub neej
1) Xaiv cov khoom lag luam- qib qib (xws li105℃electrolytic capacitorlos yog130℃electrolytic capacitor ).
2) Optimize tshav kub dissipation tsim (xws li ntxiv cov dab dej kub, yuam cua txias).
3) Ua kom lub zog muaj zog ntawm li 30%.
4) Siv cov khoom siv hluav taws xob tsis zoo thiab tsis muaj plua plav (IP67 thiab siab dua) hauv qhov chaw hnyav.
Lub neej ib txwm muaj ntawm cov khoom siv hluav taws xob LED yog nyob nruab nrab ntawm 25,000 thiab 100,000 teev, tab sis lub neej tiag tiag yuav tsum tau soj ntsuam tag nrho raws li cov xwm txheej saum toj no. Hauv qhov chaw siab - qhov kub thiab txias, cov khoom siv hluav taws xob tsis zoo tuaj yeem ua tsis tiav tom qab ob peb lub hlis ntawm kev ua haujlwm, thaum siab - cov qauv tsim zoo tuaj yeem kav ntev dua 10 xyoo. koj tuaj yeem yuav qhov zoo tshaj plaws coj tsav tsheb teeb los ntawmhttp://www.benweilight.com
