Daim ntawv qhia tswv yim rau Dimming LED Teeb
LED teeb pom kev zoo tau dhau los ua tus qauv xaiv rau lub zog- txhim kho kom zoo hauv tsev thiab lag luam. Cov qhov muag teev no yog tsim los kom haum cov khoom siv ib txwm siv, ua kom yooj yim los hloov cov roj teeb qub, halogen, lossis fluorescent teeb.
Txawm li cas los xij, qhov tseeb tseem ceeb feem ntau tsis saib xyuas: tsis yog txhua lub LEDs yog dimmable.
Yog tias koj npaj yuav siv koj lub LEDs nrog lub dimmer hloov, koj yuav tsum xaiv cov khoom tsim nyog thiab tejzaum nws hloov kho koj cov kev tswj dimming. Cov lus qhia no yuav pab koj nkag siab txog yuav ua li cas txheeb xyuas cov teeb ci LED, yuav ua li cas dimming ua haujlwm, thiab xav txog dab tsi rau flicker - kev paub dawb.
Koj Puas Xav Tau Dimmable LEDs?
Dimmable teeb pom kev zoo muaj qhov yoog raws - tso cai rau koj los kho qhov ci kom haum rau cov dej num sib txawv thiab kev xav. Hauv chav ua noj, piv txwv li, tej zaum koj yuav xav tau lub teeb ci rau kev ua noj thiab cov teeb pom kev zoo rau chav noj mov. Hauv cov chaw ua haujlwm, cov dimmable LEDs tuaj yeem txhim kho kev nplij siab thiab kev tsim khoom los ntawm kev cia cov neeg siv kho lawv lub teeb pom kev zoo.
Txawm li cas los xij, kev ua haujlwm dimming yuav tsum muaj ob qho tib si dimmable LEDs thiab cov dimmer sib xws. Kev siv tsis yog- qhov muag teev dimmable nrog lub dimmer yuav ua rau flickering, txo lub neej, thiab ua rau muaj kev puas tsuaj.
Yuav ua li cas paub yog tias koj lub LED yog Dimmable
Tshawb xyuas Lub Ntim lossis Cov Khoom Muag
Tsuas yog LEDs sau tias "dimmable" yuav tsum tau siv nrog dimmer keyboards. Nrhiav cov lus qhia no ntawm lub npov, nplooj ntawv khoom, lossis cov ntaub ntawv. Qee cov khoom kuj tseem tuaj yeem siv lub cim dimming (feem ntau lub voj voog nrog ib kab los ntawm nws los yog gradient arc), txawm tias tsis muaj lub cim thoob ntiaj teb.
Txheeb xyuas Dimmer Hloov Compatibility
Ntau lub dimmers qub tau tsim los rau siab -wattage incandescent qhov muag teev thiab tej zaum yuav tsis ua haujlwm zoo nrog tsawg-wattage LEDs. Yog tias koj tab tom hloov kho rau LEDs, tej zaum koj yuav xav tau hloov koj lub dimmer uas twb muaj lawm nrog LED- qauv sib xws, xws li kev taug qab -ntug lossis ntse dimmer.
Vim li cas tsis tag nrho LEDs Dimmable?
Lub dimmability ntawm LED nyob ntawm nws tus tsav tsheb -cov khoom siv sab hauv uas tswj hwm lub zog rau LED.
Tsis yog- cov tsav tsheb dimmable yog tsim los rau kev ua haujlwm qhib / tawm tag nrho.
Dimmable tsav tsheb tuaj yeem kho lub teeb pom kev zoo siv cov tswv yim zoo li Pulse Width Modulation (PWM) lossis analog dimming.
Yog tias koj sim dim qhov tsis yog -dimmable LED, tus tsav tsheb yuav ua haujlwm tsis zoo, ua rau flickering thiab tej zaum yuav ua tsis tau thaum ntxov.
LED dimming ua haujlwm li cas?
Tsis zoo li cov teeb pom kev zoo uas dim yooj yim los ntawm kev txo qhov hluav taws xob, LEDs xav tau kev tswj hwm ntau dua. Muaj ob txoj hauv kev:
Pulse Width Modulation (PWM)
Txoj kev no tig lub LED rau thiab tawm sai heev. Qhov piv ntawm ntawm - sij hawm mus rau tawm - sij hawm txiav txim siab pom qhov kaj. Txawm hais tias qhov hloov pauv sai dhau rau tib neeg lub qhov muag pom, qee lub koob yees duab tuaj yeem khaws cov flickering - ua rau PWM tsis zoo rau cov ntawv thov video.
Analog Dimming
Cov txheej txheem no txo cov hluav taws xob tam sim no rau LED. Thaum yooj yim dua, qee zaum nws tuaj yeem ua rau cov xim hloov ntawm cov qib qis heev.
Hom Dimming Controls
0-10V Dimming
Feem ntau siv nyob rau hauv kev lag luam chaw, lub kaw lus no siv qis -voltage tswj teeb liab (0-10V) los kho lub teeb theem. Nws muab cov dimming du thiab yog dav tshaj nrog cov kws tshaj lij-qib LED fixtures.
Leading -Edge (TRIAC) Dimming
Feem ntau hauv cov tsev laus, cov dimmers no ua haujlwm los ntawm kev txiav tawm ntawm qhov ua haujlwm ntawm AC zog nthwv dej. Lawv tuaj yeem ua rau buzzing lossis flickering nrog LEDs tshwj tsis yog tias ob lub teeb thiab dimmer yog tsim los ua haujlwm ua ke.
Trailing - Ntug Dimming
Zoo dua rau cov LEDs, cov dimmers txiav qhov kawg ntawm AC nthwv dej. Lawv ua haujlwm zoo dua thiab ntsiag to dua li ua -ntug dimmers thiab tau siv ntau dua hauv kev teeb tsa niaj hnub.
Cov lus pom zoo
Ib txwm siv dimmable LEDs nrog LED- ntsuas dimmers.
Yog tias flickering tshwm sim, sim ib lub dimmer sib txawv los yog sab laj nrog lub teeb pom kev zoo ntawm daim ntawv teev npe.
Rau kev txhim kho tshiab, xav txog kev taug qab -ntug, 0-10V, lossis ntse dimmers kom ua tau zoo tshaj plaws.
Los ntawm kev xaiv qhov sib xyaw ua ke ntawm qhov muag teev thiab kev tswj hwm, koj tuaj yeem txaus siab rau tag nrho cov dimming ntau thiab ntev los ntawm koj lub teeb pom kev zoo LED.
