Koj puas tuaj yeem poob koj lub teeb pom kev zoo LED?

Koj yuav tsum tau xyuas ob peb yam kom paub tseeb tias koj muaj lub teeb dimmable pib vim tsis yog txhua lub teeb ci LED tuaj yeem dim:

#1 - Nco ntsoov tias lub ntim rau txhua qhov ua tiav LED teeb pom kev zoo lossis qhov muag teev koj yuav tau qhia meej tias lawv yog dimmable. Qhov no yuav tsum tau ua kom pom tseeb hauv lub teeb qhov kev piav qhia lossis specs. Lub neej ntev ntawm lub teeb yuav luv luv yog tias koj muab lub LED tsis dimmable rau ntawm lub dimmer vim yog qhov ntau dhau flickering uas yuav tshwm sim.

Qee zaus, ib qho kos npe zoo li hauv qab no yog siv los qhia tias lub teeb yuav dim; tu siab, tsis muaj ib lub cim universal.

Vim li cas ho tsis muaj teeb meem yuav dim?

Tus tsav tsheb LED uas lub teeb siv tau txiav txim siab seb lub teeb LED puas yuav dim.

Txhua lub teeb LED muaj tus tsav tsheb, uas hloov hluav taws xob hluav taws xob mus rau qhov tsis tshua muaj hluav taws xob tsis tu ncua los ntawm LEDs rau kev ua haujlwm. Tsis paub meej txog LED tsav tsheb? Saib peb daim ntawv qhia tsav tsheb ua tiav LED.

Koj muaj cov khoom kim heev ntawm kev xaiv txhua tus tsav tsheb LED koj xaiv, nrog rau cov kev xaiv dimming koj xav tau, yog tias koj tab tom tsim koj tus kheej teeb siv cov khoom siv LEDs. Txawm li cas los xij, koj tsuas tuaj yeem xaiv los ntawm cov chaw tsim khoom xaiv qhov teeb tsa dimming thaum yuav khoom tiav LED teeb lossis teeb.

Tsis-dimmable LED tsav tsheb tsuas paub ON thiab OFF raws li lub xeev. Tus neeg tsav tsheb tsis-dimmable yuav sim kho thiab tswj qhov tam sim no yog tias koj pib hloov qhov tam sim no mus rau lub teeb LED. Thaum kawg, tus tsav tsheb LED yuav dhau los ua haujlwm thiab tsis ua haujlwm.

Ntawm qhov tod tes, cov tsav tsheb dimmable yog tsim los tswj cov kev hloov pauv tam sim no. Dimmable tsav tsheb yuav poob rau LED siv analogue lossis pulse width modulation (PWM) dimming los ua qhov poob tam sim no.

Yuav ua li cas LEDs dimmed precisely?

Thaum tsim lub LED retrofit, dimming yuav tsum raug coj mus rau hauv tus account kom zoo vim tias LEDs npub txawv ntawm qhov chaw teeb pom kev zoo qub.

Siv lub teeb incandescent ua ib qho kev piav qhian

Los ntawm cua sov ib lub xaim filament kom txog thaum nws ci, lawv tsim lub teeb. Tsuas yog txo qhov hluav taws xob kom nws npub; Raws li cov hlau txias, lub teeb tsawg dua yog tsim. Raws li koj tuaj yeem poob ntawm 0 mus rau 100 feem pua ​​​​los ntawm kev hloov pauv qhov hluav taws xob mus rau lub teeb ci, qhov no yog ib qho piv txwv ntawm analogue dimming.

Hloov cov rhuab filament, LED qhov muag teev siv diodes los tsim lub teeb. Lub diode tsuas muaj ob lub xeev ua tau: ON, qhov twg nws emitting lub teeb, thiab OFF, thaum nws yog, koj twv nws, tsaus.

Vim li no, tsim cov dimmable LED teeb pom kev zoo yuav tsum muaj txoj hauv kev sib txawv dua li qhov dimming LEDs. Pulse Width Modulation (PWM) thiab analogue dimming yog ob txoj kev yooj yim rau dimming LEDs.

Modulation of pulse width (PWM)

Los ntawm kev kho lub sijhawm ntev lub teeb liab yog ON lossis OFF, PWM muab ntau yam dimming. Lub teeb-emitting diode tsuas yog ON lossis OFF ntawm ib lub sijhawm thaum siv PWM dimming. Qhov no yog qhov txawv ntawm analogue dimming, uas dims LEDs los ntawm kev hloov lub zog tso zis.

Yog tias koj xav poob ib qho LED rau 80 feem pua ​​​​qhov ci ci nrog cov mem tes dav hloov kho, koj yuav ua kom lub LED rau 80 feem pua ​​​​ntawm lub sijhawm thiab tua nws rau lwm 20 feem pua. Yuav ua li cas peb thiaj tsis pom LED tig rau thiab tawm? Nws ua rau tsim nyog tias koj yuav muaj kwv yees li 80 feem pua ​​​​ntawm cov teeb pom kev zoo.

PWM dimming siv qhov teeb meem hauv tib neeg lub zeem muag. Tib neeg lub qhov muag pom tau los ntawm kwv yees li 50 mus rau 90 Hz, yog li lub teeb ci ntsa iab ntawm qhov nrawm nrawm uas tib neeg lub qhov muag tsis tuaj yeem pom nws (txog 60 thav duab ib ob). Peb lub hlwb sau cov qhov khoob kom peb qhov muag pom kev zoo thaum lub teeb ci ntsa iab sai heev.

PWM dimming yuav tsum tau siv nrog ceev faj, tshwj xeeb tshaj yog tias koj xav siv lub teeb rau kev yees duab lossis yees duab. Lub koob yees duab zoo tshaj plaws yuav tsis xav txog kev ntes me ntsis strobe thaum lub teeb tau teeb tsa rau theem qis, txawm tias tib neeg lub qhov muag yuav tsis tuaj yeem ntes PWM flickering. Thaum ua haujlwm nrog videography, koj yuav tsum tshawb nrhiav qhov zoo dua dimming dua li PWM.

Digital dimming

Yog tias koj tau nyeem peb cov lus qhia ntawm kev tsav tsheb LEDs, koj paub tias analogue dimming txo qis npaum li cas ntawm lub teeb LED tawm los ntawm kev kho qhov tam sim no mus rau nws. Txawm hais tias nws yuav tshwm sim zoo li lwm txoj hauv kev yooj yim dua rau dimming, LED cov xim yuav qee zaus hloov ntawm cov theem tam sim no, uas ua rau muaj teeb meem nrog lub teeb pom kev zoo thiab qhov sib xws.

Dab tsi Dimming yam kuv yuav tsum ntiav, ces?

Lub peev xwm los hloov lub teeb sai sai ntawm qhov dim mus rau qhov kaj yog qhov tseem ceeb tshaj plaws ntawm kev dimming. Thaum kawg, nws tso siab rau hom dimming uas koj tus tsav tsheb LED thiab / lossis lub teeb tuaj yeem txhawb nqa, tab sis yog tias koj tab tom tsim koj tus kheej, koj tuaj yeem txiav txim siab koj tus kheej. Yog tias txhua yam koj xav tau yog cov lus qhia, txav mus rau cov npe ntawm peb cov kev xaiv sab saum toj dimmer hauv qab no.

0-10V dimming

Qhov style ntawm dimming no tau txais kev nyiam rau cov teeb pom kev zoo fluorescent hauv kev lag luam. Cov xov xwm zoo yog tias nws tseem tuaj yeem siv rau kev teeb tsa LED, ua rau nws yog qhov kev xaiv nrov rau kev hloov kho cov teeb fluorescent tshwj xeeb. Ib qho tshwj xeeb DC voltage teeb liab nrog xoom mus rau kaum volt voltage ntau yog siv los tswj lub teeb. Tam sim no koj nkag siab lub npe? Raws li qhov tshwm sim, lub teeb tswj tau tuaj yeem ua haujlwm nrog 100 feem pua ​​​​tso tawm thaum siv qhov hluav taws xob tag nrho thiab 0 feem pua ​​​​tso tawm thaum tsis muaj hluav taws xob siv. Thaum qhov voltage theem ntawm kev tswj teeb liab sib txawv, yog li qhov ci ntawm koj lub teeb.

Txiav-Edge Dimming

Cov txheej txheem siv dimming feem ntau yog ua ntug dimming, tseem hu ua rau pem hauv ntej-txiav, incandescent, lossis TRIAC dimming.
Raws li nws zoo meej rau kev siv hluav taws xob siab, uas feem ntau cov cuab yeej cuab tam teeb pom kev zoo xav tau, hom dimmer no muaj nyob rau hauv feem ntau ntawm cov tsev. Qhov teeb meem tseem ceeb nrog TRIAC dimming yog tias lub teeb yuav qee zaus buzz lossis flicker. Qhov no tuaj yeem tshwm sim los ntawm kev vibrations coj los ntawm AC teeb liab txiav.

Luckily, ntau qhov tsis ntev los no TRIAC dimmers tau txiav txim siab qhov no thiab ua cov kauj ruam los tiv thaiv flickering.
