Basic LED Dimming Guidelines

Xyuas lub teeb.

Xaiv lub dimmable LED teeb yog tias koj xav kom cov nyhuv dim. Ntawm cov khoom ntim thiab cov npe hauv online, cov tuam txhab lag luam feem ntau pom cov duab hauv qab no.

Siv lub dimmer tsim nyog, thov.

Raws li kuv tau piav qhia, koj tuaj yeem siv lub teeb ci LED nrog lub teeb pom kev zoo. Koj tuaj yeem sim siv tus qauv lossis txawm tias lub ntug dimmer nrog lub teeb uas tsis yog-dimmable. Txawm li cas los xij koj yuav tsis tuaj yeem tau txais qhov kev dimming zoo tshaj plaws yog tias koj ua li ntawd. Flickering thiab buzzing teeb meem yuav txhim kho, cov nyhuv dimming yuav tsis muaj zog lossis raws li qhov xav tau, thiab lub teeb thiab dimmer yuav ua rau muaj kev puas tsuaj. Qhov kev xaiv zoo tshaj plaws yog siv lub dimmer uas yog sib xws, zoo li lub ntug dimmer.

Xyuas cov chaw tsim khoom cov kab kos duab sib raug zoo raws li cov lus qhia. Kev coj ua ntawm kev ntsuas qhov muag teeb nrog ntau lub dimmers los txiav txim siab seb qhov twg ua haujlwm nrog lawv tau txais los ntawm cov tuam txhab. Lawv tsim lawv daim ntawv qhia kev sib raug zoo tom qab kev sim, siv cov ntaub ntawv sau. Koj tuaj yeem paub tseeb tias koj tau txais txoj cai dimmer hloov thawj zaug los ntawm kev saib ntawm cov chaw tsim khoom cov kab kos kev sib raug zoo.

1.3 Xaiv qhov sim thiab qhov tseeb.

Ntau lub tuam txhab tau txeeb lub sijhawm kom tau txais txiaj ntsig nyiaj txiag los ntawm kev lag luam LED loj hlob. Txawm li cas los xij, qee cov tuam ntxhab tau tsim cov qij LED nrog subpar Cheebtsam. Yog li ntawd, muaj ib tonne ntawm subpar LED khoom nyob rau hauv kev ua lag luam uas tsis ua hauj lwm zoo li lawv yuav tsum, hnav sai sai, los yog txawm ntes hluav taws. Tsis txhob ntxhov siab los ntawm kev tso koj qhov kev txiav txim nrog tus neeg muag khoom muaj kev ntseeg siab uas tuaj yeem ua kom muaj kev ua tau zoo thiab kev nyab xeeb.

Tsim ib tug mockup.

Sim txhim kho lub teeb ntawm koj lub dimmer sai li sai tau thaum koj muaj. Xyuas kom tseeb tias koj muaj lub dimmer thiab tsawg kawg yog ib lub teeb pom kev zoo. Tshawb xyuas seb puas yuav muaj teeb meem nrog buzzing, strobing, lossis flickering. Thaum cov teeb meem no tshwm sim, koj yuav xav tau yuav lub teeb tshiab lossis dimmer. Ntawm qhov tod tes, yog tias tsis muaj teeb meem, koj tuaj yeem txuas ntxiv mus. Tam sim no koj tuaj yeem ntsib qhov fading. Tshawb xyuas seb qhov twg haum koj qhov chaw zoo.

Nrog kuv dimmer, kuv tuaj yeem siv ntau lub teeb LED?

Overloading dimmers yog ib qho yuam kev. Qhov no tuaj yeem ua rau muaj teeb meem xws li flickering, buzzing, strobing, thiab lwm yam teeb meem uas tshwm sim thaum siv dimmers uas tsis sib haum nrog LED qhov muag teev. Yuav ua li cas peb thiaj paub tias muaj pes tsawg lub teeb peb dimmer tuaj yeem ua tau?

Siv cov qauv ncaj nraim hauv qab no:

Siv 10 npaug ntawm dimmer qhov qis tshaj plaws.
Siv 10 npaug ntawm dimmer qhov siab tshaj plaws load.

Piv txwv:

Dimmer muaj qhov ntsuas 100W txog 400W.
Qhov tsawg kawg nkaus load rau lub dimmer yog 100W / 10=10W.
Dimmer 400W / 10=40W yog qhov siab tshaj plaws load.

Qhov no qhia tau hais tias cov dimmable LED qhov muag teev muaj peev xwm muaj zog ntawm 10W txog 40W.

Tom ntej:

LED qhov muag teev 'ua ke wattages yuav tsum raug suav.

Piv txwv

4 x 5W = 20W

Lub dimming yuav ua haujlwm raws li tau npaj tseg vim tias tag nrho cov wattage ntawm plaub lub teeb yog 20, uas yog nyob rau hauv qhov ntsuas ntawm 10W txog 40W.

1. Tag nrho cov wattage yuav tsum ntau tshaj qhov dimmer qhov tsawg kawg nkaus xam load tab sis tsis yog nws qhov siab tshaj plaws kom nws ua haujlwm zoo. Siv qhov muag teev los ntawm tib hom thiab cov chaw tsim khoom raws li qhov ua tau vim tias cov chaw tsim khoom sib txawv tuaj yeem tsim cov qij nrog cov khoom sib txawv, uas tuaj yeem ua rau muaj teeb meem dimming.

Yog li, LED teeb pom kev zoo tuaj yeem dim? Nws txawv. Qee lub teeb LED tsis tuaj yeem dim. Txawm li cas los xij, kev txhim kho dimmable LED teeb yuav tsum tsis txhob nyuaj. Txuas ntxiv yog tias koj muaj tus lej tsim nyog ntawm kev sim thiab ua pov thawj dimmable LED teeb thiab qhov sib txuam dimmer hloov. Nrog kev nyab xeeb thiab kav ntev, koj yuav tsis tsuas txo koj cov nqi zog tab sis kuj tau txais lub dimmer xav tias koj xav tau rau koj chav.
