Tam sim no ntawmLEDnce vim ntau yam hauv kev siv. Lub sijhawm no, kev tiv thaiv kev tiv thaiv yuav tsum tau ua kom ntseeg tau tias LED yuav tsis raug puas tsuaj vim tias qhov tam sim no nce siab tshaj ib lub sijhawm thiab amplitude. Siv cov cuab yeej tiv thaiv hluav taws xob yog qhov yooj yim tshaj plaws thiab kev tiv thaiv kev lag luam. Qhov feem ntau siv tiv thaiv keeb rauLED teebCircuit Court tiv thaiv yog varistor.

Varistor yog siv los tiv thaiv LED teeb. Nws tuaj yeem hais tau tias tsis muaj teeb meem dab tsi ntawm cov khoom siv hluav taws xob, kev hloov hluav taws xob thiab cov khoom siv hluav taws xob yog siv rau cov teeb ci LED, yuav tsum muaj kev tiv thaiv zoo li no. Nws yog siv los tiv thaiv lub surge voltage uas feem ntau tshwm sim nyob rau hauv lub nroog lub hwj chim network. Lub thiaj li hu ua surge voltage feem ntau yog lub sij hawm luv luv high-voltage mem tes tshwm sim los ntawm xob laim stroke lossis pib thiab nres ntawm cov khoom siv hluav taws xob siab. xob laim stroke yog qhov laj thawj tseem ceeb. Hluav taws xob tua tuaj yeem muab faib ua hluav taws xob ncaj qha thiab hluav taws xob tsis ncaj. Lub teeb hluav taws xob ncaj qha txhais tau hais tias xob laim tawm tsam lub zog hluav taws xob sib txuas ncaj qha, uas tsis tshua muaj, thiab feem ntau cov hluav taws xob hluav taws xob loj loj muaj kev tiv thaiv hluav taws xob tiv thaiv lawv tus kheej. Indirect xob laim stroke yog hais txog lub surge kis ntawm lub hwj chim daim phiaj induced los ntawm xob laim. Qhov kev nce siab no yuav tshwm sim heev, vim tias 1800 thunderstorms thiab 600 xob laim tshwm sim thoob plaws ntiaj teb txhua lub sijhawm. Txhua qhov hluav taws xob tawm tsam yuav ua rau muaj hluav taws xob hluav taws xob nyob rau ntawm daim phiaj hluav taws xob nyob ze. Qhov dav ntawm surge pulse feem ntau tsuas yog ob peb qhov hloov maj mam lossis luv dua, thiab qhov amplitude ntawm mem tes yuav siab li ntau txhiab volts. Feem ntau vim nws qhov siab amplitude, nws muaj kev cuam tshuam loj tshaj plaws ntawm kev puas tsuaj ntawm cov khoom siv hluav taws xob. Yog tsis muaj kev tiv thaiv, txhua yam khoom siv hluav taws xob tau yooj yim puas. Hmoov zoo, surge tiv thaiv yog yooj yim heev. Tsuas yog ntxiv ib qho tshuaj tiv thaiv surge varistor, uas feem ntau yog txuas nrog ua ke ua ntej lub rectifier.

Lub hauv paus ntsiab lus ntawm no varistor yog raws li nram no: muaj ib tug nonlinear resistor uas nws tsis kam yog nyob ze rau lub qhib Circuit Court nyob rau hauv lub cheeb tsam uas tau teev tseg, thiab thaum lub thov voltage tshaj qhov pib, nws kuj yog ze rau xoom tam sim ntawd. Qhov no ua rau nws yooj yim rau nqus cov surge. Ntxiv mus, varistor yog ib qho khoom siv rov qab tau. Tom qab surge absorption, nws tuaj yeem ua lub luag haujlwm tiv thaiv.
