Qhov tseem ceeb tshaj plaws ntawm dimming yog tso cai rau tus neeg siv los kho lub teeb theem ntawm qhov tsaus ntuj mus rau super ci hauv vib nas this. Thaum kawg, nws nyob ntawm seb hom dimming koj lub teeb LED thiab / lossis LED tsav tsheb tau sib xws tab sis yog tias koj tab tom tsim koj tus kheej teeb, koj tuaj yeem xaiv rau koj tus kheej. Yog tias koj tab tom nrhiav kev pom zoo, ces hla mus rau peb Cov Lus Pom Zoo Sab saum toj Dimmer hauv qab no.
0-10V Dimming
Hom dimming no tau nrov heev rau kev lag luam teeb pom kev zoo fluorescent. Qhov zoo yog nws tuaj yeem ua haujlwm zoo rau kev teeb tsa LED ib yam nkaus li yog qhov kev xaiv nrov thaum rov kho cov teeb fluorescent tshwj xeeb. Kev tswj ntawm lub teeb yog ua los ntawm kev mob siab rau DC voltage teeb liab uas nyob ntawm xoom mus rau 10 volts. Nkag siab lub npe tam sim no? Qhov no tso cai rau lub teeb tswj tau ua haujlwm ntawm 100% lub teeb tawm thaum lub zog tag nrho dhau los thiab 0% tso tawm thaum tsis muaj hluav taws xob dhau los. Lub brightness ntawm koj lub teeb hloov nyob rau hauv tandem nrog rau theem voltage ntawm lub teeb liab tswj.
Leading Ntug Dimming
Ua ntug dimming (tseem hu ua rau pem hauv ntej-txiav, incandescent lossis TRIAC dimming) yog txoj kev dimming tshaj plaws.
Feem ntau ntawm cov dimmers no yog TRIAC Dimmers uas theem txiav AC waveform thaum pib (ua ntug) uas txo cov hluav taws xob tam sim no lub teeb tau txais.
Hom dimmer no tau teeb tsa hauv ntau lub tsev vim nws yog qhov zoo tagnrho rau kev siv hluav taws xob siab uas feem ntau cov teeb pom kev zoo yuav tsum tau ua. Qhov teeb meem loj tshaj plaws nrog TRIAC dimming yog qee zaum muaj buzzing lossis flickering ntawm lub teeb. Qhov no tuaj yeem tshwm sim los ntawm kev vibrations uas tshwm sim los ntawm cov teeb liab AC chopped.
Ua tsaug ntau tus tshiab TRIAC dimmers tau coj qhov no mus rau hauv tus account thiab tau ceev faj kom tsis txhob flickering. Koj yuav pom ntau lub dimmable LED tsav tsheb lossis LED dimmers daim ntawv lo raws li tus qauv tsim tsis muaj flicker. Xyuas kom tseeb tias koj ua koj cov kev tshawb fawb thiab nrhiav tau qhov zoo dimmer, koj tuaj yeem pib ntawm peb cov lus pom zoo hauv qab no.
Trailing Ntug Dimming
Ib qho trailing ntug dimmer yog ib daim ntawv tsawg dua ntawm dimming. Qhov no tau pom tom qab ua-ntug dhau los ua tus qauv thiab zoo dua rau cov teeb pom kev tsis tshua muaj hluav taws xob zoo li LEDs. Vim tias nws yog hom tsis tshua muaj qhov dimming, nws tsis yog siv ntau npaum li koj xav.
Es tsis txhob txiav lub waveform ntawm qhov pib, qhov trailing ntug txiav qhov trailing ntug ntawm AC sine yoj. Qhov no txwv qhov kev dhia loj dua hauv qhov hluav taws xob uas tshwm sim hauv qhov ua ntej dimming vim hais tias lub waveform txiav tawm thaum nws twb nyob rau qhov qis qis.
Kev txwv qhov dhia loj yuav zam qhov teeb meem flickering uas tshwm sim nrog LEDs thiab TRIAC dimming. Txawm li cas los xij, zoo li peb tau hais saum toj no, cov thawj coj dimming tau txais tos kev nce qib hauv kev tshawb fawb thiab thev naus laus zis uas tau txiav cov teeb meem no tawm lawm.
