LED Teeb Dimming: Yam Koj Yuav Tsum Paub
Koj tus nqi teeb pom kev zoo tuaj yeem txo qis los ntawm kev hloov mus rau LED teeb los ntawm cov teeb pom kev zoo. Tab sis yog tias koj lub tsev muaj dimmers, tej zaum koj yuav nug yog tias LED teeb tuaj yeem dim.
Cov lus teb yooj yim yog "yog" Nws yog qhov tseeb tias LED teeb tuaj yeem dimmed. Txawm li cas los xij, muaj ob peb yam tseem ceeb, uas koj yuav tsum xav txog.
Nco ntsoov yuav dimmable LED teeb.
Feem ntau ntawm LED teeb hnub no tuaj yeem dim, tab sis qee qhov ua tsis tau. Yog li ntawd, xaiv cov teeb pom kev zoo LED thaum mus yuav khoom rau LED qhov muag teev. Cov ntaub ntawv no yog tej zaum muaj nyob rau hauv cov khoom ntsiab lus qhov rai.
Yuav ua li cas tshwm sim yog tias lub teeb ci LED uas tsis tuaj yeem dim tau siv rau ntawm lub dimmer?
Koj lub teeb ci LED yuav, qhov zoo tshaj, tsis ploj kom raug. Hauv qhov xwm txheej phem tshaj plaws, lub teeb yuav raug mob.
Qhov teeb meem yog qhov kho tau LED teeb muaj cov cuab yeej tshwj xeeb. Lawv muaj peev xwm tsim nyog rau kev hloov pauv hauv qib vim qhov no. Tsis yog-dimmable LED qhov muag teev, ntawm qhov tod tes, tsis muaj qhov txuas ntxiv no thiab tuaj yeem tsuas yog ON lossis OFF nkaus xwb. Hauv qhov tseeb, qhov no txhais tau hais tias yog tias lawv raug xa mus rau cov pa hluav taws xob lossis cov hluav taws xob qis, lawv cov circuits yuav tsis muaj peev xwm thiab tuaj yeem raug mob.
Qhov ntev thiab luv ntawm nws yog qhov uas tsis yog-dimmable LED teeb yuav tsum tsis txhob siv nrog lub dimmer.
Xyuas kom tseeb tias koj cov dimmers uas twb muaj lawm tau sib xws nrog cov qij LED tshiab.
Kuv tuaj yeem txiav txim siab tam sim ntawd yog tias kuv cov dimmers yav dhau los yuav ua haujlwm tsis zoo nrog cov qij LED tshiab?
Peb nquag tau txais qhov kev nug no. Tu siab, tsuas yog ntsia ntawm koj qhov kev hloov uas twb muaj lawm yuav tsis qhia koj seb nws puas yuav ua haujlwm nrog Lub Teeb Tshiab. Dimmer keyboards uas muaj ntau thiab niaj hnub qee zaus ua haujlwm zoo nrog Teeb thiab qee zaus tsis ua. Koj yuav tsum sim koj cov dimmers yav dhau los txhawm rau txiav txim siab seb lawv puas ua haujlwm nrog LEDs.
Qee hom dimmers tsis ua haujlwm zoo nrog LEDs vim tias lawv yuav tsum muaj zog tsawg. Koj tuaj yeem pom cov hauv qab no yog tias lub dimmer tsis ua haujlwm nrog LEDs:
LED teeb qhov muag teev muaj qhov me me dimmer ntau yam (feem ntau 60 feem pua rau 80 feem pua ntawm qhov tsis sib xws rau 100 feem pua ntawm cov teeb pom kev zoo), yog li lawv yuav tsis tuaj yeem tua ntawm qhov qis tshaj plaws dull. Feem ntau, qhov no tshwm sim vim hais tias tus neeg tswj xyuas xav tias lub teeb LED raug kaw vim nws siv lub zog qis.
Lub tswv yim zoo tshaj plaws ntawm kev nqis tes ua yuav yog los yuav ib qho LED dimmer yog tias koj ntsib ib qho los yog ob qho tib si ntawm cov teeb meem no.
Ob hom dimmers feem ntau siv hauv tsev yog:
Leading edge dimmers feem ntau tsis sib xws nrog cov teeb ci LED tshiab vim tias lawv tau tsim los ua haujlwm nrog cov teeb pom kev zoo.
Dimmers nrog ib tug trailing ntug yog tsim tshwj xeeb tshaj yog rau LED teeb. Yog li ntawd, peb qhia koj kom yuav ib qho trailing ntug dimmer yog tias koj yav dhau los dimmer tsis ua haujlwm zoo nrog LEDs.
Lawv ntau yam ntawm wattages yog thawj qhov sib txawv ntawm ob lub dimmers. Incandescent teeb siv ntau lub zog, raws li koj tuaj yeem paub (uas yog, lawv muaj wattage siab). Tsuas yog daim ntawv thov high-wattage tau sib xws nrog cov ntug dimmers. Tab sis LED teeb siv me me hluav taws xob (uas yog, lawv tsis muaj wattage). Leading edge dimmers thiaj li nyuaj kom nkag siab lossis tswj lawv cov circuits.
Txawm li cas los xij, trailing ntug dimmers tsis cuam tshuam los ntawm tsawg zog ntau yam, thiab vim li ntawd, lawv tau sib xws nrog LED teeb.
