LED sawb teeb yog cov cuab yeej teeb pom kev zoo rau txhua qhov haujlwm. Tab sis qee zaum, koj yuav xav kom muaj qee theem ntawm kev tswj hwm lub teeb ci ntawm LED sawb.
Piv txwv li, tej zaum koj yuav xav siv lawv ntawm qhov ci ntsa iab thaum nyeem phau ntawv, tab sis tom qab ntawd dim lawv tom qab rau lub teeb pom kev zoo.
Yog tias koj tsis meej pem txog yuav ua li cas kom ua tiav, nyeem rau kom paub koj tus kheej nrog LED sawb dimming txoj kev!
Ua ntej, kom paub meej: Txhua yam LED strips yog dimmable
Thaum koj mus kav khw rau cov teeb pom kev zoo hauv tsev xws li A-style qhov muag teev, koj yuav pom ntau zaus pom TSIS DIMMABLE teev nyob rau hauv cov lus piav qhia ntawm cov khoom. Yog vim li cas qee qhov LED qhov muag teev tsis yog dimmable yog vim qhov tseeb tias cov hluav taws xob hluav taws xob hauv lub teeb LED tsis tsim los tuaj yeem txhais cov teeb liab dimming ntawm phab ntsa dimmer, uas, dhau los, yog / tau tsim los rau ib txwm muaj. lub teeb incandescent.
Ntawm qhov tod tes, LED strips tsis yog tsim los txuas ncaj qha rau cov kab hluav taws xob (xws li 120V AC phab ntsa socket), thiab yuav tsum muaj lub zog hluav taws xob los hloov cov hluav taws xob ntau dua AC mus rau qis dua 12V lossis 24V DC voltage.
Yog li ntawd, yog tias phab ntsa dimmer koom nrog, nws yuav tsum xub "sib tham" rau cov khoom siv hluav taws xob ua ntej kev dimming tuaj yeem tshwm sim ntawm LED sawb. Yog li ntawd, cov lus nug dimmable / tsis dimmable nyob ntawm lub hwj huam mov, thiab seb nws puas tuaj yeem txhais cov teeb liab dimming uas tsim los ntawm phab ntsa-dimmer.
Ntawm qhov tod tes, zoo tag nrho LED strips (raws li nyob rau hauv, lub strip nws tus kheej) yog dimmable. Muab qhov tsim nyog DC hluav taws xob teeb liab (feem ntau PWM), txhua lub teeb ci LED tuaj yeem hloov kho dawb.
Peb yuav ua li cas thiaj paub tseeb tias LED sawb tau txais qhov tseeb DC hluav taws xob teeb liab kom dim zoo? Hauv qab no, peb yuav mus dhau ob txoj kev xaiv ntau tshaj plaws.
Kev xaiv 1: Siv cov tsoos TRIAC Phab Ntsa Dimmer + TRIAC Dimmable Power Supply
Yog tias koj nyiam qhov muaj thiab cov qauv ntawm cov tsoos phab ntsa dimmers thiab tab tom nrhiav rau ib qho elegant, ruaj khov LED sawb installation (xws li hauv qab txee teeb pom kev zoo), qhov no yog qhov zoo tshaj plaws koj thawj koom ruam.
Feem ntau cov phab ntsa dimmers uas muaj niaj hnub no siv TRIAC dimming teeb liab, thiab yog li ntawd, koj yuav tsum xub nrhiav TRIAC dimmable fais fab mov.
Lub TRIAC dimmable fais fab mov muaj ob txoj haujlwm ntawm no -
1) txo thiab kho 120V AC teeb liab mus rau 12/24V DC teeb liab sib xws nrog LED sawb, thiab
2) txhais ib qho TRIAC dimming teeb liab tsim los ntawm phab ntsa dimmer, thiab tom qab ntawd txhais qhov ntawd rau hauv cov khoom siv LED sawb teeb pom kev zoo.
Lub TRIAC dimmable fais fab mov txuas ncaj qha mus rau TRIAC phab ntsa dimmer, thiab cov zis kawg ntawm lub hwj huam mov txuas mus rau LED sawb. Txij li thaum peb tab tom ua haujlwm nrog cov xaim sab hauv hauv cov phab ntsa, cov khoom siv no yuav tsis muaj cov ntsaws lossis cov khoom sib txuas uas koj tau siv, thiab cov khoom siv hluav taws xob kuj tseem yuav zais lossis zais hauv phab ntsa lossis lub thawv hluav taws xob.
Tsis tas li ntawd, txhawm rau txo qhov cuam tshuam ntawm qhov poob qis, lub zog hluav taws xob yuav tsum nyob ze rau ntawm LED sawb li sai tau.
Nco ntsoov tias txhua qhov kev daws teeb meem uas suav nrog phab ntsa dimmer, suav nrog qhov no, cuam tshuam nrog kev sib txuas nyuaj rau cov hluav taws xob hauv hluav taws xob thiab yuav tsum tsuas yog ua los ntawm cov neeg tsim nyog thiab muaj ntawv tso cai xwb. Nco ntsoov ua raws li kev tiv thaiv kev nyab xeeb thaum ua haujlwm hluav taws xob!
Kev xaiv 2: Siv lub zog qis DC PWM Dimmer
Kev ntshai los ntawm kev cia siab ntawm messing cov xaim hauv koj cov phab ntsa? Tsis muaj teeb meem - lwm qhov kev xaiv tso cai rau koj siv cov khoom siv uas tsuas yog kos lub zog los ntawm phab ntsa tso zis.
DC PWM LED sawb dimmer tuaj yeem ntsia tau ntawm tus qauv, tsis yog-TRIAC dimamble fais fab mov, thiab LED sawb. Nws feem ntau muaj lub lem dial (potentiometer) uas kho cov teeb ci LED teeb.
Lub hwj chim mov tuaj yeem yog tus qauv DC fais fab mov thiab tsis tas yuav yog TRIAC dimmable. Cov khoom siv fais fab no feem ntau qis dua thiab yooj yim muaj, piv rau TRIAC dimmable fais fab mov.
Qhov no yog ib qho yooj yim Circuit Court tsim uas yuav ua hauj lwm zoo rau me me los yog portable installations qhov twg lub dimmer tsis tas yuav tsum tau ua nyob rau hauv lub phab ntsa. Tsis zoo li TRIAC dimamble cov khoom siv hluav taws xob, cov khoom siv fais fab no feem ntau yuav suav nrog cov qauv 2-prong plugs uas ntsaws rau hauv ib lub qhov hluav taws xob phab ntsa.
DC PWM dimmers feem ntau yog yooj yim heev los sib sau ua ke thiab txuas rau lub hwj huam mov thiab LED sawb. Waveform Lighting's FilmGrade LED Dimmer, piv txwv li, suav nrog DC plugs ntawm ob qho kawg, tso cai rau koj sib sau ua ke txhua yam hauv vib nas this yam tsis muaj cuab yeej.
Tsuas yog txuas ob lub xaim hluav taws xob los ntawm cov khoom siv hluav taws xob mus rau chav tsev dimmer, thiab tom qab ntawd ob lub xov hluav taws xob tawm ntawm LED sawb. Lub dimmer tsuas yog ua haujlwm zoo li lub valve, thiab lub tshuab hluav taws xob yuav cia li muab cov ntsuas tam sim no thiab qhov hluav taws xob nyob ntawm qhov dimmer lub pob qhov rooj.
Qhov no yog qhov yooj yim yog tias koj npaj yuav txav mus rau qhov teeb tsa LED sawb, tab sis tej zaum yuav muaj teeb meem yog tias koj tab tom nrhiav ib yam dab tsi ruaj khov lossis tsawg dua "cluttered."
Tsis tas li, lwm qhov tsis zoo ntawm txoj hauv kev no yog qhov PWM dimmer yuav tsum tau muab tso rau ze rau ntawm LED sawb. Qhov no yog vim muaj qhov tshwm sim hu ua hluav taws xob poob uas feem ntau yog qhov teeb meem nrog kev siv hluav taws xob tsawg DC nkaus xwb. Ib phab ntsa dimmer mus kom ze (Option 1) yuav tso cai rau koj kom tsis txhob muaj qhov no.
Kev txiav txim siab zaum kawg
LED sawb kev teeb tsa thiab dimming tuaj yeem ua kom yuam kev los ntawm qhov tseeb tias peb tam sim no straddle qhov tseeb hauv DC electronics thiab legacy TRIAC dimming systems uas tseem nrov hauv cov tsev uas twb muaj lawm thiab tshiab.
Nrog rau ntau yam sib txawv thiab kev sib xyaw ua ke, peb pom zoo kom kuaj xyuas kev sib raug zoo ua ntej kev tsim kho kom ruaj khov lossis loj. Qee zaum, cov teeb meem npaj txhij txog xws li tsis yog-linear dimming lossis flickering tuaj yeem tshwm sim, thiab nws yog qhov zoo tshaj los ntes cov teeb meem no kom sai li sai tau.
