Cov txiaj ntsig ntawm kev sib txuas ua ke ntawm LED teeb ntawm lub teeb ntawm lub neej
Cov txheej txheem teeb tsa ntawm LEDs ntawm lub rooj sib tham siv teeb pom kev zoo feem ntau yog ua raws plaub yam no. Hauv qab no peb yuav piav qhia kev sib raug zoo thiab kev cuam tshuam ntawm kev sib koom ua ke txheej txheem teeb tsa ntawm cov LEDs no thiab lub neej ntawm tag nrho lub teeb.
Qhov zoo: Kev tsim hluav taws xob yog yooj yim, kev faib tawm tam sim no ntawm LED yog txawm tias, tam sim no ua haujlwm ntawm cov teeb LED yog sib npaug rau cov zis tam sim no ntawm lub zog siv, Vf ntawm LED tsis xav tau kev xav, raws li lub zog hluav taws xob qhov hluav taws xob tso tawm ntau, tsuav yog tsis muaj luv luv ntawm cov lej loj ntawm LEDs, lub teeb tuaj yeem lav tau kom pom kev, tsuas yog qhov ci ci txo.
Qhov tsis zoo: Ib qho ntawm LEDs tau puas los ntawm kev qhib lub Circuit Court, thiab tag nrho lub teeb tsis qhib, ua rau muaj kev rau txim loj ntawm kev tua lub teeb. Ntxiv mus, cov tsav hluav taws xob tso tawm hluav taws xob kuj tseem siab, thiab cov rwb thaiv tsev xav tau rau aluminium substrate yog qhov siab.
Qhov Zoo: Qhov hluav taws xob tso tawm ntawm lub zog hluav taws xob tau qis, thiab cov txheej txheem tsim khoom yog yooj yim. Thaum ob peb txoj hlua ntawm Vf nyob hauv tib lub xeev, tag nrho cov teeb ua haujlwm ib txwm muaj, thiab kev ua haujlwm tam sim no ntawm LED tsis hloov pauv.
Qhov tsis zoo: Qhov xav tau Vf rau LEDs yog qhov nruj. Yog tias Vf qhov sib txawv yog qhov loj, qhov kev faib khoom tam sim no tsis txawm tias. Thaum Vf ntawm txoj hlua qis dua, qhov ua haujlwm tam sim no ntawm txoj hlua no nce nrawm dua, qhov kub siab dhau, thiab lub teeb pom kev zoo yog qhov hnyav. Yog tias ib leeg LED tawg, qhov tam sim no hauv txoj hlua no yuav nce nrawm dua, thiab LED yuav qhib dua tam sim no. Lub sijhawm no, txhua qhov tsav tsheb tam sim no yuav raug xa mus rau lwm lub LEDs, thiab txhua lub LEDs yuav ua haujlwm nyob rau lub sijhawm tam sim no, thiab Vf yuav qis dua. Ib txoj hlua tam sim no yuav loj dua, ua rau muaj kev puas tsuaj rau tag nrho cov LEDs ua kom sov, tag nrho lub teeb tawm mus, thiab yuav luag tag nrho cov LEDs muaj teeb pom kev loj heev, thiab tsis muaj tus nqi kho. Yog tias ib qho LED qhib, yuav tau txais cov txiaj ntsig zoo ib yam.
Qhov Zoo: Qhov sib faib tas li tam sim no tau txais yuav, thiab Vf ntawm LED tsis suav nrog. Yog tias ib leeg LED tawg, nws yuav tsis cuam tshuam rau kev ua haujlwm ib txwm ntawm lwm cov LEDs. Yog tias ib qho LED qhib, txoj hlua no yuav tsis pom kev, thiab lwm txoj hlua tuaj yeem ua haujlwm ib txwm muaj, Tam sim no ruaj khov, tsis cuam tshuam rau kev ua haujlwm ib txwm ntawm lwm cov hlua, thiab yuav tsis ua rau muaj teeb meem loj ntawm kev tua lub teeb. Kev nthuav tawm txoj haujlwm yog qhov yooj yim dua. Cov haujlwm ntxiv ntawm qhov ntsuas tam sim no tuaj yeem rov tsim dua, thiab ntau yam kev tiv thaiv kev ua haujlwm xws li ntsuas kub, tswj lub sijhawm, dimming thiab lwm yam haujlwm tuaj yeem ntxiv.
Qhov tsis zoo: Lub Circuit Court yog qhov nyuaj, qhov yuav tsum tau ua kom zoo ntawm cov neeg ua haujlwm yog tus neeg siab, thiab tus nqi nce me ntsis.
Qhov Zoo: Yog tias Vf ntawm LED yog nyob ze, qhov kev sib tw tseem ruaj khov. Qhov sib txuas sib txuas ntau dua, kev nyab xeeb siab dua ntawm qhov Circuit no.
Qhov tsis zoo: Yog tias Vf ntawm ib qho LED qis dua, tom qab ua haujlwm tam sim no ntawm cov LED no yuav loj dua, ua rau lub teeb pom kev zoo lossis dhau tam sim no qhib Circuit Court, thiab tsis cuam tshuam rau lwm yam LEDs. Kev faib tawm tam sim no ntawm tib kem sib luag yuav nce me ntsis. Yuav ua rau muaj teeb meem loj ntawm kev kaw lub teeb.
Muaj ntau txoj hlua teeb, qhov hluav taws xob tau siab, thiab cov kab sib dhos sib luag tau raug txo qis, tom qab ntawd qhov ua haujlwm tau zoo yuav siab dua, feem ntau ntawm 12-24 hlua, teeb lub teeb hlaws teeb feem ntau yog 3.125v, tam sim no 3528 yog 18ma, tawm mus ib qho npoo, lub teeb Lub neej ntawm cov hlaws yuav ntev dua.
Cov khoom siv hluav taws xob yuav tsum muaj qhov tam sim no los tiv thaiv lub teeb hlaws.
