Kev tshuaj xyuas ntawm cov laj thawj rau kev nyiam ntawm cov tsis-cais LED raj
Kev tshuaj xyuas ntawm cov laj thawj rau kev nyiam ntawm cov tsis-cais LED tube Kev thaiv thiab hloov pauv muaj ntau qhov zoo, uas tau piav qhia hauv qab no rau koj qhov kev siv
Txawm hais tias muaj ntau hom thiab hom kev faib tawm ntawm cov raj LED, nws yog kiv taub hau me ntsis, tab sis muaj ib hom raj LED uas txawv raws li hom khoom siv hluav taws xob. Niaj hnub no peb tham txog cov hlab uas tsis muaj kev sib cais coj los siv.
Txawm hais tias muaj ntau hom khoom siv hluav taws xob siv los ntawm peb lub raj LED, xws li zoo ib yam, dimming, xwm txheej ceev, induction, tsis muaj dej, thiab lwm yam, hauv cov lus yooj yim, nws yog qhov sib txawv ntawm kev rho tawm thiab tsis cais tawm. Qhov ntawd' nws yog.
Txhawm rau muab nws yooj yim, cov khoom siv hluav taws xob sib cais cais qhov hluav taws xob siab ntawm qhov nkag qhov kawg los ntawm qhov hluav taws xob qis ntawm qhov tso tawm kawg kom tiv thaiv hluav taws xob thiab txo qhov kev pheej hmoo.
Txhawm rau muab nws yooj yim, cov khoom siv hluav taws xob tsis sib cais txhais tau hais tias lub davhlau ya nyob twg thiab lub davhlau ya nyob twg tsis raug cais los ntawm kev hloov pauv, thiab qhov hluav taws xob tau txo qis, tab sis muaj qee qhov nqi hluav taws xob los tsav lub teeb roj fluorescent LED kom ua haujlwm. Lub hom phiaj ntawm no yog dab tsi? Cov txiaj ntsig yog dab tsi?
Lub hom phiaj ntawm lub teeb uas tsis cais LED teeb yog: Ua ntej, lub zog siv hluav taws xob dhau los ua qhov yooj yim thiab cov qauv tsis nyuaj. Nyob rau hnub ntxov ntawm kev cais cov khoom siv hluav taws xob, muaj ntau yam ntxiv. Txhawm rau kom ua tiav kev sib txuas, lub tshuab hloov pauv tau ntxiv hauv nruab nrab, thiab qhov hloov pauv tau poob loj. Tsis yog kev cais tawm tuaj yooj yim, lub zog muab ntim tau zoo heev. Tsuas yog yuav tsum tau hloov txoj hlua thiab teeb meem ua ke ntawm LED teeb hlaws, tuaj yeem txhawb nqa lub teeb LED hlaws kom tso lub teeb.
Cov txiaj ntsig ntawm cov raj tsis-cais LED yog dab tsi?
Qhov Zoo 1. Tus nqi qis: Raws li tau hais ua ntej, vim yog cov qauv yooj yim, siv cov khoom siv hluav taws xob tsawg dua, tus nqi tag nrho raug txo, thiab tus nqi tuaj yeem pheej yig heev. Piv txwv li, tus nqi ntawm cov khoom siv hluav taws xob sib cais yog siab li kaum yuan, thiab cov khoom siv hluav taws xob uas tsis cais tawm tsuas yog nqi ob peb yuan. Qhov sib txawv yog ob peb zaug, suav txog tus nqi ntawm cov teeb roj fluorescent LED, thiab qhov cuam tshuam tseem loj.
Cov txiaj ntsig 2.It yog qhov ua tau zoo; qhov ua tau zoo ntawm cov khoom siv hluav taws xob raug cuam tshuam los ntawm kev hloov pauv cais, thiab kev hloov pauv tau raug txo. Tsis yog kev cais tawm tsis muaj qhov tsis txaus no, thiab kev ua haujlwm tau zoo, siab txog li 92%, uas yog qhov tseem ceeb rau qhov xav tau tshaj plaws ntawm kev ua kom pom kev zoo.
Cov txiaj ntsig 3 lub voj voog tsim khoom; vim kev yooj yim, kev tsim khoom yooj yim thiab ua tiav, koom nrog kev tsim khoom sai, cov khoom nyoos tsawg dua, tus nqi qis, thiab xa khoom sai, koj tseem tuaj yeem khaws cov khoom siv raw, tsis txo nqi, thiab muaj ntau yam xws li cov khoom lag luam qis.
Lub tshuab hluav taws xob yog lub cuab yeej hloov pauv AC voltage, tam sim no, thiab qhov tsis muaj zog. Thaum AC tam sim no dhau los ntawm thawj kauj, AC sib nqus flux tau tsim tawm hauv cov hlau hlau, ua rau muaj qhov hluav taws xob kom raug rau hauv cov kauj thib ob. Lub tshuab hloov pauv yog tsim los ntawm cov tub ntxhais hlau thiab cov kauj. Lub kauj muaj ob lossis ntau qhov txuas. Cov cua txuas nrog lub zog hluav taws xob tau hu ua thawj qhov cua, thiab cov cua txuas ntxiv yog hu ua theem nrab cua. Hauv lub tshuab hluav taws xob, txawm tias lub kauj txav los ntawm qhov sib nqus lossis qhov sib nqus sib nqus txav los ntawm cov kauj ruaj khov, nws tuaj yeem ua rau muaj hluav taws xob muaj peev xwm hauv cov kauj. Hauv ob qho tib si, tus nqi ntawm cov hluav taws xob sib nqus tseem tsis hloov pauv, tab sis tus nqi sib nqus sib nqus sib tshuam nrog lub kauj sib txawv. Hloov pauv, qhov no yog lub hauv paus ntsiab lus ntawm kev sib koom tes. Transformer yog cov cuab yeej siv hluav taws xob sib koom ua ke hloov pauv qhov hluav taws xob, tam sim no thiab tsis muaj zog. Transformer siv lub hauv paus ntsiab lus ntawm hluav taws xob nqus hluav taws xob los hloov cov hluav taws xob hluav taws xob lossis cov cim qhia los ntawm ib qho Circuit Court mus rau lwm qhov.
Yog li ntawd, tus hloov pauv yog ib yam khoom siv hloov pauv, uas tuaj yeem hloov pauv lub zog, thiab yuav muaj teeb meem kev hloov pauv. Cov khoom siv hluav taws xob sib cais muaj cov hloov pauv sib cais, thiab kev hloov pauv tau yog qhov tsawg dua li ntawm cov khoom siv hluav taws xob uas tsis muaj kev cais tsis muaj cov hloov pauv.
Kev hloov pauv ua tau zoo yog qhov sib piv ntawm lub zog tso tawm ntawm lub zog hluav taws xob rau lub zog tawm tswv yim: uas yog, kev siv hluav taws xob hloov pauv=lub zog tso tawm tam sim muab los ntawm lub hwj chim muab rau tus tswv tsev/lub zog tam sim ntawm lub zog tawm tswv yim × 100% .
Feem ntau hais lus, PC cov khoom siv hluav taws xob tshwj xeeb muaj qee qhov xav tau rau kev hloov pauv tau zoo. Thaum pib, lub zog hloov pauv tau zoo tsuas yog kwv yees li 60%. Hauv Intel's ATX12V 1.3 lub zog qhia tshwj xeeb, kev hloov pauv ntawm lub zog siv hluav taws xob yuav tsum tsis pub tsawg dua 68% thaum thauj khoom tag nrho. Hauv ATX 12V 2.01, qhov xav tau siab dua tau tso rau pem hauv ntej rau kev hloov pauv kev ua haujlwm ntawm lub zog siv ─ Tsis tsawg dua 80%. Yog li ntawd, thaum yuav khoom siv hluav taws xob, txhua tus tuaj yeem nkag siab zoo txog kev hloov pauv hluav taws xob los ntawm cov khoom siv hluav taws xob tshwj xeeb nws ua raws.
Lub zog siv hluav taws xob=lub zog tso tawm/lub zog tawm tswv yim*100% PF yog lub zog muaj zog=COSΦ=lub zog muaj zog P/pom lub zog S Tam sim no feem ntau ntawm cov khoom siv hluav taws xob LED tau hloov pauv cov khoom siv hluav taws xob, kev ua tau zoo tuaj yeem nce mus txog 96%; tab sis tus nqi ntawd siab heev. Feem ntau hais txog 90%, qis dua tus nqi no, qhia tias thev naus laus zis, cov khoom siv, cuab yeej siv, thiab qhov zoo yog qhov nruab nrab. Kev taug qab: Yuav ntsuas ntsuas zis thiab lub zog tawm tswv yim li cas, COS yog dab tsi? Puas yog lub zog muaj zog hais txog lub zog siv los ntawm lub teeb ci? Pom tseeb lub zog? Nws nyob qhov twg? Teb: Feem ntau hais lus, lub hwj chim nkag ntawm lub zog hloov hluav taws xob suav nrog lub zog pom tseeb, lub zog muaj zog thiab lub zog rov ua haujlwm. Qhov fais fab feem ntau siv hauv kev hloov pauv tam sim no. Lub zog tso tawm yog lub zog tso tawm ntawm lub zog hloov hluav taws xob. Pom pom lub zog tau txhais los ua tus nqi muaj txiaj ntsig ntawm qhov hluav taws xob nkag tau sib npaug los ntawm tus nqi muaj txiaj ntsig ntawm cov tswv yim tam sim no. Lub zog muaj zog yog qhov txiaj ntsig zoo ntawm kev siv hluav taws xob sib npaug los ntawm cov txiaj ntsig muaj txiaj ntsig ntawm cov tswv yim tam sim no thiab tom qab ntawd suav nrog qhov muaj zog. Nws ua haujlwm, tab sis nws yog qhov tsis tseem ceeb hauv kev muab hluav taws xob. Lub zog muaj zog faib los ntawm lub zog pom tseeb yog lub zog. Lub zog tso tawm yog ntsuas tau yooj yim. Cov zis DC voltage sib npaug los ntawm cov zis DC tam sim no yog lub zog tso tawm. Lub zog tso tawm faib los ntawm lub zog tawm tswv yim yog qhov ua tau zoo ntawm lub zog siv! Ib-theem watt-teev ntsuas ntsuas lub zog ua haujlwm, thiab tseem muaj cov ntsuas uas tuaj yeem ntsuas lub zog rov ua haujlwm.
