Thawj qhov hluav taws xob input rau LED sawb teeb yog 12 Vdc thiab 24 Vdc, feem. Lawv muaj kev nyab xeeb thiab yooj yim ua haujlwm nrog. Tab sis, peb feem ntau hnov cov lus no: LED strip yog ci dua ntawm ib kawg thiab dimmer ntawm lwm qhov. Vim li cas?
Cov lus teb yog voltage poob. Qhov tseeb, qhov no yog qhov qub heev hauv cov teeb pom kev tsis tshua muaj hluav taws xob.
Hauv tsab xov xwm no peb yuav tham txog:
Dab tsi yog LED strip voltage poob?
LED strip voltage poob yog tus nqi ntawm qhov hluav taws xob poob ntawm lub hwj chim mov thiab LEDs lawv tus kheej.
Qhov ntau dua qhov kev tiv thaiv hauv Circuit Court, qhov voltage poob ntau dua.
Nyob rau hauv DC Circuit Court ntawm cov coj sawb, qhov voltage yuav maj mam txo qis thaum nws dhau los ntawm cov hlau thiab lub teeb sawb nws tus kheej. Yog li, qhov txuas ntxiv ntawm cov hlau los yog sawb yuav ua rau ib sab ntawm koj cov sawb teeb ci dua li lwm sab.
Vim li cas LED strip voltage poob tshwm sim?
Thawj qhov laj thawj yog qhov ntev ntawm cov xaim muaj qee qhov hluav taws xob tsis kam. Qhov ntev ntawm cov hlau, qhov ntau qhov tsis kam. Hluav taws xob tsis kam ua rau qhov poob qis, thiab qhov hluav taws xob poob ua rau koj cov LEDs dim.
Qhov thib ob yog vim li cas PCB nws tus kheej muaj qhov tsis kam. Kev tiv thaiv ntawm PCB yuav siv ib feem ntawm qhov hluav taws xob thiab hloov hluav taws xob hluav taws xob mus rau lub zog thermal.
PCB tsis kam yog cuam tshuam rau qhov loj ntawm qhov sib tsoo (suav nrog PCB board dav thiab tooj liab thickness). Qhov loj dua ntawm PCB cross-section, qhov me dua qhov tsis kam; qhov ntev ntawm PCB ntev, qhov ntau dua qhov kev tiv thaiv.
Yuav ua li cas nrhiav tau voltage poob?
LED qhov hluav taws xob poob yog qhov pom tau zoo tshaj plaws ntawm lub teeb coj dawb yog li koj tuaj yeem qhib lub teeb dawb ntawm cov xim hloov xim coj los saib xyuas qhov hluav taws xob poob.
Cia peb saib yog tias peb tuaj yeem pom qhov hluav taws xob poob los ntawm kev khiav mus deb ntawm lub teeb dawb coj sawb. Hauv daim duab hauv qab no, peb tuaj yeem pom tias qhov pib (txoj hauj lwm "1") yog dawb dawb, thiab tom qab khiav mus rau qhov deb (txoj hauj lwm "2"), lub teeb dawb maj mam tig daj, thiab thaum kawg ntawm cov coj sawb ( txoj hauj lwm "3"), lub teeb dawb tig liab vim qhov txo qis hauv voltage.
(Nco ntsoov: Thaum lub teeb coj lub teeb yog dov, nws yuav tsum tsis txhob teeb rau lub sijhawm ntev, uas yuav ua rau lub teeb ci ntsa iab.)
LED strip voltage muaj feem xyuam rau LED chips. Hauv qab no yog rau pem hauv ntej voltages xav tau rau ob peb xim nti drives.
- Blue LED nti: 3.0-3.2V
- Ntsuab LED nti: 3.0-3.2V
- Liab LED nti: 2.0-2.2V
Nco ntsoov: Cov LED dawb siv lub nti xiav thiab tom qab ntawd ntxiv phosphor rau saum npoo.
Kev tsav tsheb hluav taws xob ntawm cov chips xiav yog ntau dua li ntawm cov chips ntsuab thiab liab. Yog li thaum qhov hluav taws xob ntawm lub teeb dawb coj sawb poob qis, thiab qhov tam sim no qhov hluav taws xob tsis tuaj yeem ua tau raws li qhov yuav tsum tau muaj los ntawm xiav chips, lub teeb sawb yuav pom daj (ntsuab & liab sib xyaw xim) thiab liab vim tias lawv qis dua qhov voltage xav tau los ntawm lub teeb dawb.
Puas yog tag nrho LED sawb teeb muaj qhov hluav taws xob poob?
Yeej, txhua qhov qis-voltage LED strips, xws li 5Vdc, 12Vdc, thiab 24Vdc yuav muaj teeb meem voltage poob. Vim hais tias rau tib lub zog siv, qhov qis dua qhov voltage, qhov tam sim no ntau dua. Raws li Ohm txoj cai, qhov hluav taws xob sib npaug sib npaug los ntawm qhov tam sim no. Qhov tsis kam ntawm tus neeg xyuas pib yog qhov tsis tu ncua. Qhov tam sim no ntau dua, qhov voltage poob ntau dua. Qhov no kuj yog vim li cas tib neeg siv high voltage xa hluav taws xob!
High voltage LED strips, xws li 110VAC, 220VAC, thiab 230VAC, feem ntau tsis muaj teeb meem ntawm voltage poob. Rau ib qho kawg fais fab noj, qhov siab tshaj plaws khiav deb ntawm high-voltage LED teeb strips tuaj yeem ncav cuag 50 meters. Raws li lub zog sib npaug ntawm qhov sib npaug ntawm qhov tam sim no, qhov hluav taws xob ntawm high-voltage LED sawb yog 110V lossis 220V, yog li tam sim no ntawm high-voltage LED strip yog me me, yog li qhov voltage poob kuj me me.
cov tsis tu ncua tam sim no LED teeb sawb, feem ntau 24Vdc, yuav tsis muaj teeb meem ntawm voltage poob. Vim hais tias tam sim no cov LED strips muaj ICs, cov ICs tuaj yeem ua kom cov tam sim no ntws los ntawm LEDs tas li. Ntev npaum li qhov tam sim no los ntawm LED tsis tas li, qhov ci ntawm LED kuj tseem nyob tas li.
Qhov tseeb, qhov voltage ntawm qhov tam sim no LED lub teeb yuav txo qis. Piv txwv li, qhov voltage ntawm qhov kawg ntawm qhov tsis tu ncua tam sim no LED teeb sawb kuj tseem yuav qis dua 24V. Raws li qhov xwm txheej ib txwm muaj, qhov hluav taws xob poob yuav ua rau poob tam sim no los ntawm LED, ua rau qis qis dua. Txawm li cas los xij, vim tias muaj ICs ntawm cov kab hluav taws xob tam sim no tsis tu ncua, cov ICs no tuaj yeem khaws cov tam sim no dhau los ntawm LEDs tas li, uas yuav tsum nyob rau hauv qhov tshwj xeeb voltage (piv txwv li, 24V ~ 19V).
Puas yog LED strip voltage poob teeb meem?
LED sawb voltage poob yog feem ntau tsis cuam tshuam rau LEDs vim nws yog ib daim ntawv uas qhov hluav taws xob muab rau lawv tsawg dua li qhov xav tau thaum xub thawj.
Txawm li cas los xij, qhov poob qis feem ntau sawv cev rau kev hloov pauv ntawm hluav taws xob hluav taws xob mus rau lub zog thermal ntawm cov resistor, uas ua rau muaj cua sov ntau. Qhov no tuaj yeem ua rau muaj teeb meem yog tias koj lub sawb LED tau teeb tsa hauv lossis ze rau cov khoom siv hluav taws xob. 3M adhesives thiab LEDs kuj yog ib qho thermally rhiab heev yog li qhov hluav taws xob ntau dhau tuaj yeem ua teeb meem.
