Yuav ua li cas yog tias koj tso hluav taws xob ntau dhau los ntawm LED

Feem ntau, qhov hluav taws xob ntau dhau yog tsim teeb meem. LED teeb qhov muag teev thiab lwm yam khoom siv hluav taws xob tuaj yeem raug puas tsuaj los ntawm qhov hluav taws xob surges. Nyob ntawm seb hom thiab xim ntawm LED, ib qho kev xav tau ntau npaum li cas ntawm cov volts. Nrog LEDs, feem ntau cov kws tshaj lij qhia siv 2-3 volts. Kom paub meej, koj tuaj yeem ua qee qhov kev tshawb fawb.

Kab lus no hais txog dab tsi tshwm sim thaum lub LED tau txais hluav taws xob ntau dhau thiab yuav ua li cas kom tsis txhob nws.

Direct Current (DC) lossis Alternating Current (AC) LED teeb?

Vim lawv cov qauv tsim, LEDs tsuas yog kis tau tam sim no hauv ib lub polarity. Feem ntau, cov resistors, voltage regulators, thiab tam sim no regulators yog siv los tswj cov tam sim no thiab voltage muab rau LEDs thaum lawv tau tsav los ntawm DC voltage qhov chaw.

Ntau npaum li cas voltage LED teeb tuaj yeem tiv taus ib zaug?

LED voltage yog VL (4V lossis 2V rau dawb thiab xiav LEDs). LED tam sim no yuav tsum tsawg tshaj li qhov LED tau tsim los ua haujlwm ntawm nws qhov siab tshaj plaws. Qhov ib txwm 5 hli inch LEDs 'qhov siab tshaj plaws tam sim no feem ntau yog 20mA. Yog li ntawd, rau feem ntau ntawm cov circuits, 15mA thiab 10mA yog qhov zoo tagnrho.

Ib qho hluav taws xob tshwj xeeb, xws li 24 lossis 12V, yog xav tau rau LED teeb. Lawv tau kub heev thaum ua haujlwm ntawm cov hluav taws xob ntau dua. LED teeb los yog cov soldering nyob ib ncig ntawm lawv raug mob los ntawm kev kub siab heev. Kev puas tsuaj thaum tshav kub kub ua rau cov teeb ci LED ploj, flicker, lossis txawm tawm mus tag.

Yuav ua li cas tshwm sim rau ib qho LED thaum muaj hluav taws xob ntau dhau los ntawm nws?

Txhawm rau muab nws yooj yim, qhov hluav taws xob ntau dhau ua rau lub teeb ci LED. LEDs yog cov khoom siv tam sim no-tsav, tsis yog cov khoom siv hluav taws xob, raws li tau hais lawm. Yog li, LED teeb yog fused tawm yog tias qhov hluav taws xob hloov pauv ntau dua 10 feem pua. Qhov hluav taws xob nce siab tom qab ntawd ua rau muaj kev puas tsuaj rau LED qhov muag hluav taws xob cov khoom siv hluav taws xob. LED tsav tsheb thiab cov vaj huam sib luag xa tawm deteriorate ua ntej ntawm qhov hluav taws xob ntau dhau. Tsis tas li ntawd, nws ua rau ntau qhov kev pabcuam LED teeb pom kev zoo.

LEDs muaj zog heev. Qhov ntau qhov hluav taws xob koj nce, qhov kub ntau lawv yuav tsim, uas tsis zoo. Lub LED tsim teeb tsawg dua thiab muaj lub neej luv dua thaum nws kub dhau. Ib qho kev ua haujlwm tsis zoo ntawm LED muaj feem cuam tshuam nrog txo lub teeb.

Ntau npaum li cas Voltage Ua LEDs xav tau?

Yog tias koj muaj ob peb LEDs txuas nrog hauv cov koob, koj yuav tsum coj mus rau hauv tus account tag nrho cov tom ntej voltages. Tab sis, yog tias koj lub voj voog nyob rau hauv qhov sib npaug, koj yuav tsum coj mus rau hauv tus account rau pem hauv ntej voltage ntawm tag nrho cov LEDs nyob rau hauv txhua strand.

Yuav ua li cas tiv thaiv overstressing LED Voltage

Ib qho LED uas tau raug hluav taws xob dhau kev ntxhov siab (EOS) yuav tsum raug suav tias yog ib qho khoom siv uas tuaj yeem ua tsis tiav. Ib qho qhib Circuit Court ntsib qhov tsis ua haujlwm vim muaj zog heev. Nws yog ib qho tseem ceeb rau kev ntsuam xyuas tam sim no ripple thiab tso zis tolerances thaum twg ib tug tshiab tam sim no fais fab mov raug xaiv. Tshawb xyuas lub hotplug tam sim no thiab ntu ntu ntu thaum lub sijhawm hloov pauv thiab hloov-tawm theem kuj tau qhia. Tej zaum lawv yuav yog stealth LED killers uas ua rau cov khoom tiv thaiv kev ncaj ncees covertly thiab tsis tawm hauv qhov pom.

Txhawm rau kom tsis txhob muaj hluav taws xob dhau kev ntxhov siab tsis ua haujlwm, nws yog ib qho tseem ceeb uas yuav tsum tau siv lub zog hluav taws xob nrog lub caij nplooj ntoo hlav thaum lub sijhawm hloov tawm thiab nyob rau theem. Qhov siab tshaj plaws ntsuas tam sim no rau LED yuav tsum tsis pub tshaj los ntawm cov khoom siv fais fab.

Qhov tseem ceeb tshaj plaws, qhov niaj zaus tam sim no yuav tsum tsis txhob tshaj qhov siab tshaj plaws tam sim no uas LED tuaj yeem tiv taus thaum ua ke nrog ripple thiab zoo kam rau ua. Los ntawm kev ua kom paub tseeb tias cov kev cai no tau ua tiav, koj tuaj yeem tiv thaiv hluav taws xob los ntawm kev ntxhov siab los ntawm kev siv hluav taws xob hluav taws xob.

Siv lub zog hluav taws xob nrog kev tiv thaiv luv luv yog lwm cov txheej txheem los tiv thaiv qhov hluav taws xob puas rau LED. Tom ntej no, ntxiv ib lub diode rau LED board nyob rau hauv parallel nrog cov hlua LED uas yog powered los ntawm qhov opposite kev taw qhia. Yog tias koj siv lub connector los txuas cov khoom siv hluav taws xob rau LED board, lub polarized connector yog qhov kev xaiv zoo tshaj.

Yuav Ua Li Cas Ntsuas Kuv Lub Teeb LED Qhov Voltage

kom paub tseeb tias koj lub teeb LED qhov voltage thiab tam sim no;

Nrhiav nws hauv daim ntawv qhia.

Siv lub multimeter nrog lub diode feature, txiav txim siab qhov voltage ntawm LED.

Txuas lub roj teeb, potentiometer, thiab LED ua ke. Pib nrog lub siab tsis kam teeb tsa ntawm lub potentiometer, tom qab ntawd maj mam txo qis kom txog thaum lub teeb pom kev txaus.

Cov kab hauv qab ntawm Kev Lag Luam-qib LED teeb yog tsim los tiv thaiv cov xwm txheej zoo li no uas yuav raug coj los ntawm hluav taws xob ntau dhau. Ua ntej thiab tom qab kev yuav khoom, nco ntsoov xyuas cov kev ntsuas hluav taws xob ntawm koj lub teeb ci LED los txiav txim seb koj puas tuaj yeem ua tau raws li qhov tshwj xeeb.

Lub teeb Unlimited LED

Tus thawj distributor thiab khw muag khoom ntawm hwm LED hlua teeb yog LED Teeb Unlimited. Txhawm rau nrhiav pom yam koj xav tau, saib los ntawm peb qhov dav ntawm LED teeb qhov muag teev.

Lus Cim: Peb cov khoom ua raws li ROHS cov cai. Qhov no qhia tau hais tias thaum peb paub tias lawv tuaj yeem muaj cov hmoov txhuas, cov nyiaj nyob rau hauv qhov kev txwv.

480 Volt Led Noob
