Cov khoom siv hluav taws xob hauv LED hloov hluav taws xob muaj xws li LED diodes, IGBTs, thiab MOSFETs. SCRs feem ntau yog siv nyob rau hauv lub input rectifier Circuit Court thiab soft-pib Circuit Court ntawm switching fais fab mov. Vim qhov nyuaj ntawm kev tsav tsheb GTRs thiab lawv qhov hloov pauv tsawg, lawv tau maj mam hloov los ntawm IGBTs thiab MOSFETs.
Cov khoom siv hluav taws xob hloov hluav taws xob LED muaj peb qhov yuav tsum tau ua: lub zog hluav taws xob cov khoom siv hluav taws xob yuav tsum ua haujlwm hauv lub xeev hloov pauv tsis yog lub xeev tsis yog -linear; lawv yuav tsum ua hauj lwm ntawm ib tug high zaus es tsis yog ib tug tsawg zaus; thiab cov zis yuav tsum yog DC es tsis yog AC. Cov input ports ntawm switching fais fab mov yog cim nrog cov ntawv; txuas lawv raws li cov ntawv. V + txuas mus rau LED zoo davhlau ya nyob twg, V- txuas rau LED tsis zoo davhlau ya nyob twg, thiab L thiab N txuas rau AC220V.
Ib qho kev hloov pauv LED, tseem hu ua lub tiaj tus - rov pib dua LED qhov taw qhia hloov, yog lub vaj huam sib luag tiaj tus hloov nrog qhov tsis siv neeg rov pib dua. Qhov kev hloov pauv muaj xws li qhov taw qhia LED uas qhia meej txog lub xeev qhib / tawm, ua rau nws yooj yim rau cov neeg siv nrhiav qhov hloov pauv hauv qhov tsaus ntuj.
Tsav los ntawm kev txhim kho thev naus laus zis, qhov tseeb ntawm cov cuab yeej siv thiab cov cuab yeej siv tau nce ntxiv, ua rau muaj kev xav tau ntau dua rau cov khoom siv hluav taws xob. Cov khoom siv hluav taws xob sib txawv, 60Hz cov khoom siv hluav taws xob sib txawv, 400Hz cov khoom siv hluav taws xob nruab nrab zaus, thiab ib zaug - cov khoom siv hluav taws xob sib txawv ntawm cov khoom siv hluav taws xob yog li ntawd tau txais kev nyiam nyob hauv khw.
Kev ua lag luam muaj ntau yam khoom siv hluav taws xob sib txawv thiab ib zaug - cov khoom siv hluav taws xob sib txawv, nrog rau qib sib txawv. Cov neeg tsim khoom yuav tsum tau them sai sai rau cov khoom siv hluav taws xob hluav taws xob, qhov zaus, qhov tso zis hluav taws xob, thiab cov yam ntxwv thauj khoom thaum xaiv ib qho. Nyob rau tib lub sijhawm, kev sib raug zoo ntawm qhov sib txawv ntawm cov khoom siv hluav taws xob sib txawv thiab lub cev muaj zog yuav tsum raug txiav txim siab kom ua tiav nws lub zog - txuag thiab ruaj khov zoo thiab ua kom cov khoom siv ua haujlwm zoo.
Cov khoom siv los nag rau LED hloov cov khoom siv hluav taws xob yuav tsum ua kom tsis muaj dej tsis zoo los lav kev ua haujlwm ib txwm nyob hauv ib puag ncig sab nraum zoov. Xaiv qhov kev ntsuas dej tsis zoo thiab kev tiv thaiv kev tiv thaiv kom ruaj khov ntawm cov khoom siv hluav taws xob hauv huab cua hnyav.
LED switching fais fab mov muaj ntau yam kev siv, tsis tsuas yog nyob rau hauv lub teeb pom kev zoo, tab sis kuj nyob rau hauv kev tswj ntawm ntau yam industrial cov cuab yeej thiab cov cuab yeej. Lawv kev ruaj ntseg thiab kev ntseeg tau ua rau lawv nyiam lub zog daws teeb meem rau ntau yam kev thov.
