Puas yog LED DIODE AC lossis DC?

Cov yam ntxwv hluav taws xob ntawm Led
Ua cov ntaus ntawv semiconductor, LED tau muaj cov yam ntxwv uas muaj Diode, uas yog xa mus tom ntej conduction thiab thim rov qab. Nyob rau hauv pem hauv ntej voltage, tus nqi resistance ntawm Led nrawm txo qis, tam sim no nce, thiab kev siv luminous tseem yuav ua rau muaj kev cuam tshuam ntau ntxiv; Nyob rau hauv kev thim rov qab, LEDs yog yuav luag tsis-}} thiab cov khoom lag luam yuav luag tsis muaj qhov kaj. Tsis tas li ntawd, Volt merer amperor nkhaus ntawm LED qhia tau tias qhov kev ua haujlwm hluav taws xob) thiab ua haujlwm tam sim no ntawm LED kev cuam tshuam rau nws txoj kev ua haujlwm zoo heev thiab cov nyiaj.
Cov ntsiab lus yooj yim ntawm Alternating tam sim no thiab ncaj qha tam sim no
Hloov lwm yam tam sim no (AC) hais txog qhov kev taw qhia thiab kev hloov siab kawg nyob rau lub sijhawm. Feem ntau ntawm cov hluav taws xob siv nyob rau hauv cov tsev neeg thiab hauv lub zog hluav taws xob yog hloov tshiab tam sim no. Ib qho txiaj ntsig tseem ceeb ntawm kev hloov pauv tam sim no yog tias qhov hluav taws xob hloov tau yooj yim los ntawm kev hloov pauv, ua rau nws muaj kev sib hloov ntev thiab xa tawm.
Direct tam sim no (DC) yog hais txog qhov kev coj tam sim no tas li, thiab nws qhov ntau yuav txawv tab sis nws cov kev coj ruaj ruaj. Cov khoom plig tam sim no los ntawm cov roj teeb, hnub ci ci, thiab DC cov chaw muaj peev xwm yog txhua qhov hluav taws xob. Direct tam sim no tau siv dav hauv cov hluav taws xob hluav taws xob, tshwj xeeb tshaj yog cov xwm txheej hluav taws xob thiab cov khoom siv hluav taws xob ruaj khov, thiab lwm yam.
Kev sib raug zoo ntawm LED diodes nrog AC thiab DC lub zog
Los ntawm cov yam ntxwv hluav taws xob thiab ua haujlwm ntawm LED, LED Diode yog qhov tseem ceeb DC ntaus ntawv. Txawm hais tias LEDs tuaj yeem ua haujlwm hauv qab kev hloov tam sim no, hauv kev muaj tiag, muaj ntau yam teeb meem nrog kev tsav tsheb ncaj qha.
Tsis khov Lumcence: Vim yog cov kev hloov pauv ntawm AC tam sim no, kev hloov pauv ntawm lub teeb tam sim no, ua rau muaj kev tsis txaus ntseeg thiab cuam tshuam rau kev pom kev.
Kev pheej hmoo ntawm kev puas tsuaj: lub Peak voltage hauv AC fais fab yuav tshaj qhov ntsuas hluav taws xob ntawm cov LED, ua rau muaj kev cuam tshuam thiab kev puas tsuaj rau cov LED. Ib qho ntxiv, Harmonic Cheebtsam hauv lwm txoj kev hloov tshiab tam sim no kuj tseem muaj kev cuam tshuam tsis zoo.
Ua tsis tiav: ncaj qha siv AC Faisd rau tsav LEDs yuav tsum tau them ntxiv cov nqi sib ntxiv tab sis kuj txo cov txheej txheem ua haujlwm.
Hauv kev sib piv, siv ncaj qha tam sim no los tsav LEDs muaj ntau yam zoo:
Sab ruaj khov Linescence: Taug kev tam sim no muaj ruaj khov tam sim no thiab voltage, kom ruaj khov coj mus ua luminence ntau dua thiab txhim kho pom cov teebmeem.
Tiv thaiv LEDs: Los ntawm kev tswj hwm qhov tseeb thiab tam sim no tau tiv thaiv los ntawm kev puas tsuaj xws li overvoltage thiab overcurrent, txuas lawv lub neej kev pabcuam.
Txhim kho efficiency: ncaj qha siv DC lub zog los tsav LEDs tsis muaj kev siv hluav taws xob txo cov txheej txheem txo cov txheej txheem txo qis system thiab txhim kho cov khoom siv hluav taws xob txo qis.
Daim ntawv thov hauv kev xyaum
Hauv kev siv cov kev siv, txhawm rau siv cov txiaj ntsig zoo ntawm LED, DC hluav taws xob muab lossis DC tsav tsheb hluav taws xob feem ntau yog siv los tsav LED. Piv txwv li, hauv tshav pob ntawm LED teeb pom kev zoo, LED fixtures yog feem ntau tau nruab nrog cov peev txheej tam sim no los yog qhov ua haujlwm voltage uas tau ruaj khov los ua haujlwm ntawm cov nqi tam sim no thiab hluav taws xob. Nyob rau hauv daim teb hluav taws xob ntawm hluav taws xob, coj cov qauv coj los kuj siv DC tsav ncig kom muab ruaj khov tam sim no thiab voltage, ua kom pom kev ua yeeb yam.
Ib qho ntxiv, nrog kev txhim kho kev thev naus laus zis, qee cov ntse tau hloov kho thiab hloov kho kom haum, uas tuaj yeem hloov kho kub, uas tuaj yeem hloov kho qhov tseeb ntawm cov txiaj ntsig ntawm cov coj.
