Tam sim no, muaj covtsis cais tawmtsim thiabtsav tsheb cais tawmkev muab hluav taws xob hauv kev lag luam teeb pom kev zoo LED.
Tus qauv tsim uas tsis cais tawm tsuas yog txwv rau cov khoom uas muaj ob txheej rwb thaiv tsev xwb, xws li lub teeb hloov ntawm lub teeb, uas lub LED thiab tag nrho cov khoom tau sib xyaw ua ke thiab kaw rau hauv cov yas uas tsis ua hluav taws xob, yog li tsis muaj kev pheej hmoo ntawm hluav taws xob rau tus neeg siv kawg.
Raws li tau pom nyob rau hauvdaim duab
qhov twg tus neeg siv muaj kev nkag mus kov lub LED thiab cov xov hluav taws xob tso zis, xav tau lub zog tsav cais.
Lub transformer cais tawm lossis lub zog hluav taws xob LED tsav tsheb cais tawm txhais tau tias LED tuaj yeem kov ncaj qha los ntawm tes yam tsis raug hluav taws xob. Txawm hais tias lub zog tsav tsheb LED tsis muaj lub transformer cais tawm tseem tuaj yeem ua tiav ib feem ntawm kev rwb thaiv tsev nrog kev pab los ntawm lub plhaub tiv thaiv, lub LED tam sim no tsis tuaj yeem tiv tauj ncaj qha thaum ua haujlwm. Cov teeb insulated yuav dhau los ua mainstream yav tom ntej.
Raws li pom hauv daim duab
Lub zog fais fab ntawm LED tsav tsheb uas tsis yog cais thiab cais muaj lawv tus kheej qhov zoo thiab qhov tsis zoo, feem ntau yog los ntawm plaub lub ntsiab lus hauv qab no:
Hais txog kev nyab xeeb:Lub zog fais fab cais muaj ntau qhov zoo dua, vim tias lub zog fais fab cais nrog lub zog dav, kev ua tau zoo dua thiab ruaj khov, kuj yuav tsis ua rau muaj kev puas tsuaj rau tib neeg lub cev, thiab cov thev naus laus zis cais tau paub tab dua. Hom tsis cais qhov voltage ntau yog qhov phem dua li qhov cais, qhov voltage ntau yog nyob nruab nrab110V-300V, thiab qhov kev sib caiskev muab hluav taws xob tuaj yeem ua tau60-300V, siab thiab qis tam sim no yog sib xws heev.
Nyob rau hauv cov nqe lus ntawm kev ua haujlwm zoo:kev nyab xeeb ntawm kev tsav tsheb hom kev cais tawm tab sis kev ua haujlwm qis, kev ua haujlwm ntawm kev tsav tsheb hom kev tsis cais tawm yog siab dua.
Nyob rau hauv cov nqe lus ntawm lub circuit qauv:Cov txheej txheem cais tawm tam sim no feem ntau yog AC / DC flyback circuit scheme, yog li lub voj voog txheeb ze yog qhov nyuaj dua, kim heev. Hom tsis cais tawm yog siv DC / DC boost lossis buck circuit, lub voj voog txheeb ze yog yooj yim, yog li tus nqi qis dua.
Nyob rau hauv cov nqe lus ntawm qhov tseeb tam sim no:hom kev cais tawm tuaj yeem nyob hauv ± 5%. Hom kev tsis cais tawm yog qhov nyuaj ua tiav.
Daim Ntawv Thov:
1, IC lossis ib feem ntawm lub rooj tsavxwm fais fab mov, los ntawm tus nqi thiab ntim, xaiv cov khoom siv fais fab tsis raug cais tawm.
2, kev siv roj teeb fais fab, ntawm qhov yuav tsum tau ua haujlwm ntawm lub roj teeb, kev xaiv cov khoom siv fais fab uas tsis raug cais tawm.
