Tsib Dimming Txoj Kev ntawm LED Teeb

Rau lub teeb, dimming yog ib qho tseem ceeb heev.Dimming tuaj yeem tsis tsuas yog tsim kom muaj cua zoo xwb, tab sis kuj ua rau kom muaj kev siv tau ntawm lub teeb. Ntxiv mus, rau cov teeb pom kev zoo ntawm LED, dimming yooj yim dua rau kev paub dua li lwm cov teeb fluorescent, lub teeb txuag hluav taws xob, lub teeb hluav taws xob siab sodium, thiab lwm yam. yog qhov tsim nyog ntxiv rau kev ua haujlwm dimming rau ntau hom LED teeb.Dab tsi ntawm txoj kev dimming lub teeb muaj?

1.Leading edge theem txiav tswj dimming (FPC), tseem hu ua SCR dimming

FCP yog siv cov xov hlau uas tswj tau, pib los ntawm AC txheeb ze txoj hauj lwm 0, qhov input voltage chopping, kom txog thaum cov xov hlau tswj tau txuas nrog, tsis muaj qhov hluav taws xob tawm tswv yim.

Lub hauv paus ntsiab lus yog los kho lub conduction lub kaum sab xis ntawm txhua ib nrab-yoj ntawm alternating tam sim no los hloov lub sinusoidal waveform, yog li hloov tus nqi zoo ntawm cov alternating tam sim no, thiaj li mus cuag lub hom phiaj ntawm dimming.

Qhov zoo:

yooj yim xaim, tus nqi qis, kev hloov kho siab, kev ua haujlwm siab, me me, lub teeb yuag, thiab yooj yim tswj chaw taws teeb.Nws dominates kev ua lag luam, thiab feem ntau manufacturers cov khoom yog hom dimmer.

Qhov tsis zoo:

tsis zoo dimming kev ua tau zoo, feem ntau ua rau txo qhov dimming ntau yam, thiab yuav ua rau qhov tsawg kawg nkaus yuav tsum tau load tshaj lub rated hwj chim ntawm ib tug los yog ib tug tsawg tus naj npawb ntawm LED teeb pom kev zoo, tsis tshua muaj adaptability thiab tsawg compatibility.

2.trailing ntug txiav (RPC) MOS raj dimming

Trailing-ntug theem-txiav tswj dimmers ua nrog teb-zoo transistor (FET) los yog insulated-gate bipolar transistor (IGBT) li.Trailing ntug theem-txiav dimmers feem ntau siv MOSFETs li hloov khoom siv, yog li lawv kuj hu ua MOSFET dimmers, feem ntau hu ua "MOS tubes".MOSFET yog ib qho kev tswj tag nrho, uas tuaj yeem tswj tau los yog tawm, yog li tsis muaj qhov tshwm sim uas lub thyristor dimmer tsis tuaj yeem muab tua tag.

Tsis tas li ntawd, MOSFET dimming Circuit Court yog tsim nyog rau capacitive load dimming tshaj lub thyristor, tab sis vim hais tias ntawm tus nqi siab thiab lub complex dimming Circuit Court, nws tsis yog yooj yim kom ruaj, yog li ntawd MOS raj dimming txoj kev tsis tau tsim. , thiab SCR Dimmers tseem suav rau feem coob ntawm kev lag luam dimming.

3.0-10V DC

0-10V dimming tseem hu ua 0-10V teeb liab dimming, uas yog ib qho analog dimming txoj kev.Nws qhov txawv ntawm FPC yog tias muaj ob qhov ntxiv 0-10V interfaces (+ 10V thiab -10V) ntawm 0-10V fais fab mov.Nws tswj cov zis tam sim no ntawm cov khoom siv hluav taws xob los ntawm kev hloov qhov hluav taws xob 0-10V.Dimming yog tiav.Nws yog qhov ci tshaj plaws thaum nws yog 10V, thiab nws tawm thaum nws yog 0V.Thiab 1-10V tsuas yog lub dimmer yog 1-10V, thaum qhov kev tawm tsam dimmer raug kho kom tsawg kawg 1V, cov zis tam sim no yog 10%, yog tias cov zis tam sim no yog 100% ntawm 10V, qhov ci kuj yuav yog 100%.Nws yog ib qho tsim nyog sau cia thiab qhov zoo tshaj plaws kom paub qhov txawv yog tias 1-10V tsis muaj lub luag haujlwm ntawm kev hloov, thiab lub teeb tsis tuaj yeem hloov mus rau qhov qis tshaj plaws, thaum 0-10V muaj lub luag haujlwm ntawm kev hloov.

Qhov zoo:

zoo dimming nyhuv, siab compatibility, siab precision, siab nqi kev kawm

Qhov tsis zoo:

cumbersome wiring (xaiv yuav tsum tau nce cov teeb liab kab)

4. DALI (Digital Addressable Lighting Interface)

Tus qauv DALI tau txhais lub DALI network, suav nrog qhov siab tshaj plaws ntawm 64 units (nrog chaw nyob ywj pheej), 16 pawg thiab 16 scenes.Cov teeb pom kev sib txawv ntawm lub tsheb npav DALI tuaj yeem ua tau yooj yim pab pawg kom paub txog kev tswj hwm thiab kev tswj hwm ntawm qhov sib txawv.Hauv kev xyaum, daim ntawv thov DALI ib txwm muaj peev xwm tswj tau 40-50 lub teeb, uas tuaj yeem muab faib ua 16 pawg, thaum muaj peev xwm ua tau qee qhov kev tswj hwm / xwm txheej hauv tib lub sijhawm.

Qhov zoo:

Qhov tseeb dimming, ib lub teeb thiab kev tswj ib leeg, kev sib txuas lus ob txoj kev, yooj yim rau kev nug raws sij hawm thiab kev nkag siab ntawm cov khoom siv thiab cov ntaub ntawv.Muaj zog tiv thaiv kev cuam tshuam muaj peev xwm Muaj cov kev cai tshwj xeeb thiab cov kev cai, uas txhim khu kev sib cuam tshuam ntawm cov khoom sib txawv ntawm cov khoom sib txawv, thiab txhua lub DALI ntaus ntawv muaj qhov chaw nyob cais, uas tuaj yeem ua tiav kev tswj hwm ib leeg.

Qhov tsis zoo:

tus nqi siab thiab nyuaj debugging

5. DMX512 (los yog DMX)

DMX modulator yog lub ntsiab lus ntawm Digital Multiple X, uas txhais tau tias ntau yam kev sib kis.Nws lub npe tseem ceeb yog DMX512-A, thiab ib qho kev sib txuas tuaj yeem txuas mus txog 512 raws, yog li peb tuaj yeem paub tias cov cuab yeej no yog cov khoom siv hluav taws xob digital dimming nrog 512 dimming raws.Nws yog ib qho kev sib xyaw ua ke nti uas cais cov kev tswj cov teeb liab xws li ci ntsa iab, qhov sib piv, thiab chromaticity, thiab ua rau lawv cais.Los ntawm kev kho cov digital potentiometer, tus nqi analog tso zis theem tau hloov los tswj qhov ci thiab xim ntawm cov teeb liab video.Nws faib lub teeb rau hauv 256 theem ntawm 0 txog 100%.Lub kaw lus tswj tau tuaj yeem paub R, G, B, 256 hom grey qib, thiab paub tseeb xim tag nrho.

Rau ntau daim ntawv thov engineering, nws tsuas yog tsim nyog los teeb tsa tus tswv tsev me me hauv lub thawv xa khoom ntawm lub ru tsev, ua ntej kev pab cuam tswj lub teeb pom kev zoo, khaws cia rau hauv SD card, thiab ntxig rau hauv lub me me tswj tuav ntawm lub ru tsev. kom paub qhov teeb pom kev zoo.Dimming tswj.

Qhov zoo:

Precise dimming, nplua nuj hloov cuam tshuam

Qhov tsis zoo:

Teeb meem thaiv thiab chaw nyob sau, complex debugging

Peb tshwj xeeb hauv cov teeb dimmable, yog tias koj xav paub ntau ntxiv txog teeb thiab dimmers, lossis yuav cov dimmers featured hauv video, thovtiv tauj peb.
