LEDs paub txog lawv cov kev siv hluav taws xob tsawg thiab qhov ci ci siab.Brightness thiab lub zog noj yog ntau tshaj 60% txawv ntawm cov tsoos tungsten qhov muag teev.Tab sis tsis yog tag nrho cov qhov muag teev yog dimmable, thiab tus nqi ntawm dimmable qhov muag teev yuav kim dua, koj yuav tsum tau ntsuas koj cov kev xav tau ua ntej xaiv koj lub teeb LED.Qhov no yog qhov tseem ceeb tshwj xeeb tshaj yog thaum hloov cov teeb pom kev qub nrog cov thev naus laus zis tshiab tshiab rau thawj zaug thiab xav kom lawv dim.
Puas yog kuv lub qhov muag Edison dimmable?
Lub teeb dimmable yog lub teeb pom kev zoo uas tuaj yeem kho qhov ci ntawm lub teeb raws li cov neeg siv khoom xav tau, yog li cuam tshuam rau qhov ci ntawm lub teeb sab hauv tsev thiab coj tawm qhov sib txawv ntawm qhov chaw nyob sab hauv tsev.
Yog hais tias koj yuav ib tug tiav lawm LED fixture los yog lub teeb, xyuas kom meej lub ntim hais tias nws yog dimmable.Qhov no yuav tsum tau hais nyob rau hauv cov lus piav qhia lossis cov kev qhia tshwj xeeb ntawm lub teeb.Yog tias koj siv lub LED tsis-dimmable ntawm lub dimmer koj yuav tau txais ntau flickering thiab puas lub teeb, txwv nws txoj sia.Ib lub cim zoo ib yam li hauv qab no yog qee zaum siv los qhia lub teeb yog dimmable, hmoov tsis tsis muaj lub cim tshwj xeeb.
Feem ntau seb lub teeb pom kev tuaj yeem dim tuaj yeem pom ntawm lub ntim ntawm lub teeb, thiab cov qhov muag teev dimmable kuj tseem kim dua qhov muag teeb uas tsis yog dimmable.Dimmable teeb pom kev zoo tuaj yeem kho qhov ci ci ntawm lub teeb raws li cov neeg siv khoom xav tau, yog li cuam tshuam rau qhov ci ntawm lub teeb sab hauv tsev thiab coj tawm qhov sib txawv sab hauv ib puag ncig, txuag lub zog thiab txo cov pa roj carbon monoxide.Ntau thiab ntau cov neeg siv khoom nyiam yuav cov qhov muag teeb dimmable.
LED Edison teeb dimming txoj cai:
Raws li qhov tam sim no qhov chaw, LEDs yog inherently dimmable.Tam sim no ntws los ntawm LED teeb hlaws txiav txiav lub teeb tso zis ".Lawv qhov ci ntsa iab tuaj yeem hloov kho yooj yim los ntawm kev tswj cov energizing tam sim no ntawm cov khoom siv semiconductor txheej txuas rau lub substrate.LEDs tsis zoo li cov teeb pom kev zoo ib txwm muaj, thiab qhov dimming tsis cuam tshuam rau Efficiency thiab lub neej ntawm LEDs.Qhov tseeb, dimming tuaj yeem txo lawv qhov kub thiab txias, yog li ua kom lub neej ntev ntawm LEDs.Txhua yam khoom siv LED, yog tias nws yuav tsum tau ua rau hauv qhov hloov lub teeb lossis LED teeb, yuav tsum muaj tus tsav tsheb kom ua tiav qhov dimming.Vim hais tias LEDs yog Nws yog qhov tsawg-voltage DC qhov chaw, thiab LED xav tau tus tsav hluav taws xob los hloov AC rau hauv qhov siv tau thiab kho tau DC tam sim no.Cov tsav tsheb no tau muab faib ua peb txoj kev dimming.
Hauv pulse width modulation (PWM) hom, tam sim no los ntawm LED yog hloov mus rau thiab tawm ntawm qhov ntau zaus, "feem ntau txhiab zaus hauv ib ob", thiab tam sim no los ntawm LED yog sib npaug rau tus nqi nruab nrab ntawm lub sijhawm tam sim no. LED hloov lub voj voog."Los ntawm kev txo qis lub zog ntawm lub sijhawm ntawm LED, qhov nruab nrab tam sim no lossis qhov zoo tam sim no tuaj yeem txo qis, yog li txo qhov ci ntawm LED.Zoo li cov teeb pom kev zoo ib txwm muaj, LEDs tuaj yeem dim los ntawm kev txo qis tam sim no (CCR), lossis analog dimming.CCR khaws lub teeb ci Muaj qhov tsis tu ncua tam sim no, tab sis dimming yog ua tiav los ntawm kev txo qhov loj ntawm qhov tam sim no."Lub teeb tso zis yog proportional rau tam sim no los ntawm LED ntaus ntawv,"
PWM thiab CCR muaj qhov zoo thiab qhov tsis zoo.PWM tau siv dav dua thiab muaj qhov dav dua qhov dimming.Vim tias PWM dimming siv ceev hloov mus rau thiab tawm, nws yuav tsum muaj ntau dua thiab kim khoom siv hluav taws xob hluav taws xob los tsim cov pulses tam sim no ntawm cov zaus txaus los tiv thaiv tib neeg lub qhov muag los ntawm kev ntes lawv.flickering.CCR dimming txoj kev ua tau zoo dua thiab yooj yim dua, vim tias cov khoom siv tsav tsheb nws xav tau yooj yim dua thiab pheej yig dua.Tsis zoo li PWM, CCR tsis tsim hluav taws xob cuam tshuam EMI tshwm sim los ntawm kev hloov pauv ntau zaus.Txawm li cas los xij, CCR tsis haum rau cov ntawv thov uas qhov kev xav tau dimming tsawg dua 10%."Ntawm qhov tsis tshua muaj hluav taws xob, LEDs tsis ua haujlwm zoo thiab lub teeb pom kev zoo tsis ruaj khov.
LED Silicon tswj rectifier fais fab mov tau siv nyob rau hauv dimming ntawm incandescent teeb thiab lub zog txuag teeb ua ntej, thiab nws kuj yog cov feem ntau siv dimming txoj kev rau LED dimming.Silicon tswj rectifier yog ib hom ntawm lub cev dimming.Nws txoj haujlwm ua haujlwm yog los tsim kom muaj tangential output voltage waveform tom qab lub waveform ntawm input voltage yog txiav los ntawm lub conduction lub kaum sab xis.Kev siv lub hauv paus ntsiab lus ntawm tangential tuaj yeem txo qhov txiaj ntsig zoo ntawm qhov tso zis hluav taws xob, yog li txo lub zog ntawm cov khoom hnyav (resistive load).Silicon tswj rectifier dimmers muaj qhov zoo ntawm kev hloov kho siab, kev ua haujlwm siab, me me, lub teeb yuag, thiab yooj yim tswj chaw taws teeb.Lub teeb hloov kho yog mos thiab ruaj khov, thiab yuav tsis muaj qhov tshwm sim stroboscopic.ua lag luam.Qhov zoo ntawm Silicon tswj rectifier dimming yog kev ua haujlwm siab, kev ua haujlwm ruaj khov thiab tsis tshua muaj nqi dimming.
Peb-theem dimming ntawm peb cov khoom siv silicon tswj rectifier fais fab mov.
Dimmable teeb pom kev siv scenarios:
Dimmable teeb pom kev zoo yog siv nyob rau hauv ntau yam scenes, xws li tsev so, seev cev halls, venues, exhibition halls thiab lwm yam sij hawm uas yuav tsum tau teeb pom kev zoo, feem ntau yog los ntawm kev hloov cov nqi ntawm lub teeb los kho lub brightness ntawm lub teeb.Tam sim no tias huab cua sov dua, qhov teeb meem ntawm yuav ua li cas txo hluav taws xob siv rau teeb pom kev zoo kuj tseem yuav tshwm sim.Hmoov zoo, qhov tshwm sim ntawm LED teeb txuag hluav taws xob ntau.Nws yuav zoo dua yog tias kev tswj hwm tuaj yeem siv los txuag hluav taws xob zoo dua.Rau qhov dimming ntawm LED qhov muag teev, xws li cov phab ntsa hauv tsev, cov chaw ua haujlwm, khw malls, tsev kawm ntawv, factories thiab lwm lub sijhawm tuaj yeem hloov kho raws li qhov xav tau teeb pom kev zoo, thiab kev txuag hluav taws xob tuaj yeem ua tiav.Yog tias cov sijhawm no tau hloov pauv nrog cov teeb pom kev zoo LED, nws yuav txuag tau ntau lub zog.
Dimmable teeb pom kev zoo ua rau koj yooj yim kom phim lub teeb pom kev nyob ib puag ncig koj rau koj cov haujlwm.Tej zaum koj yuav xav tau lub teeb ci ntsa iab thaum ua haujlwm ntawm phau ntawv txheeb xyuas tab sis lub teeb ci ntsa iab thaum noj hmo.Dimming kuj tau siv ntau nyob rau hauv
kev lag luam thiab kev lag luam ib puag ncig.Ntxiv cov teeb pom kev zoo dimmable muab qhov yooj yim rau koj qhov chaw ua haujlwm thiab tso cai rau lub teeb pom kev zoo rau koj cov neeg ua haujlwm nyiam lossis xav tau.Txawm hais tias koj tab tom ntsib cov qhua, saib TV, mloog nkauj, nrog koj tsev neeg, lossis xav ib leeg, koj tuaj yeem kho qhov ci ntawm lub teeb sib txawv los tsim kom muaj kev sib haum xeeb, nyob ntsiag to, sib haum xeeb, thiab sov so, thiab kev paub tob hauv lub neej.Lub teeb mos tuaj yeem ua rau lub siab zoo, lub teeb tsawg dua thiab tsaus ntuj tuaj yeem pab xav, ntau dua thiab ci ci tuaj yeem ua rau huab cua sov dua.Txhua qhov kev xav tau yooj yim tuaj yeem ua tiav los ntawm kev ua haujlwm yooj yim tshaj plaws, thiab tsuas yog xav tau kev tswj hwm los ntawm cov keyboards ib txwm los kho lub teeb thiab qhov tsaus ntuj ntawm qhov sib txawv.
