Li cas los xaiv Led Sawb?
Ua ntej tshaj plaws, peb yuav tsum saib ntawm FPC ntawm lub teeb roj teeb, uas feem ntau hu ua Circuit Court board. Tam sim no, ntau lub lag luam nyob hauv khw kom txuag tau cov nqi. Tsuas yog siv cov xaim hluav taws xob ib leeg siv hluav taws xob los ua cov kab hluav taws xob hauv Circuit Court yuav ua rau kub taub hau yog tias lub teeb nrig siv ntev ntev. Lub neej ntawm LED yuav muaj cuam tshuam. Tsuas yog ib sab ntawm ib lub vaj huam sib luag tuaj yeem pom txoj kab, sab nraub qaum (tsis muaj LED) yog tus, xim yog yam tsis xws luag, ob tog ntawm ob lub vaj huam sib luag muaj kab.
Qhov thib ob, nws nyob ntawm kev ua haujlwm ntawm LED teeb sawb teeb. Cov puab tsaig feem ntau yog teem kab rov tav. Cov pob qij txha nyob ntawm ob sab ntawm lub teeb ua ke. Cov pob qij txha muaj tag nrho thiab ci. Ntawm qhov tsis sib xws, yog tias cov pob qij txha dub dub, nws txhais tau tias nws tau nyob hauv Tshuag rau lub sijhawm ntev. Tshwj xeeb tshaj yog rau cov kab uas hla-hla, nws yooj yim rau kev tuaj yeem cuav, thiab tus nqi ntawm kev tsis ncaj yog siab heev.
Kuj yuav tsum tau saib cov chips ntawm ED teeb, nrog DC voltage tus tswj lub teeb tsa los hloov lub voltage mus txog 6-8V, txhua lub teeb yog me ntsis kaj, tab sis ntau cov teeb meem, qhov sib xws ntawm cov chips no zoo dua, chips tsis zoo yog ob peb lub teeb me ntsis ib tsos tsaus dua, tshwj xeeb 5050 chips, ib lub nti nrog peb chips, txhua nti yog ib txwm zes, yog tias tsis yog. Los yog qhov tsis raws li lub teeb ci qis dua yog qhov qis dua.
Tus khoov LED teeb coj kev soj ntsuam thiab qhwv lub teeb ib puag ncig ntawm cov ntiv tes. Nquag, lub teeb kuj tuaj yeem pom kev ib txwm nyob. Txoj kev txom nyem tsis zoo ntawm cov roj LED teeb lossis thev tsis kam yuav ua kom tiav.
