Txhawm rau ua txoj haujlwm zoo ntawm cov khoom siv teeb pom kev zoo ntawm LED, qhov tseem ceeb ntawm cov khoom siv hluav taws xob hauv cov hluav taws xob, kev tsav tsheb fais fab thiab lub teeb pom kev zoo, thiab cov cua kub dissipation yog qhov tseem ceeb tshwj xeeb. Lub tshav kub dissipation cuam tshuam ncaj qha rau lub neej zoo ntawm cov khoom siv teeb pom kev zoo, thaum lub neej ntawm lub zog tsav tsheb nws tus kheej thiab kev ruaj ntseg ntawm cov zis tam sim no thiab qhov hluav taws xob nyob ntawm cov khoom. Tag nrho lub neej zoo kuj muaj qhov cuam tshuam loj, thiab lub teeb ci yog qhov tseem ceeb ntawm tag nrho cov khoom.
1. Dab tsi yog LED tsav tsheb fais fab mov?
LED tsav lub hwj chim qhov chaw hloov lub hwj chim mov mus rau hauv ib tug tshwj xeeb voltage thiab tam sim no tsav lub LED teeb-emitting voltage converter. Feem ntau, cov tswv yim ntawm LED tsav lub zog muaj xws li high-voltage fais fab zaus AC (ie, mains), low-voltage DC, high-voltage DC, low-voltage high-frequency. AC (xws li cov zis ntawm hluav taws xob transformer). Cov zis ntawm LED tsav tsheb feem ntau yog qhov chaw tsis tu ncua uas hloov qhov hluav taws xob raws li LED qhov kev hloov pauv mus rau pem hauv ntej. Cov khoom tseem ceeb ntawm cov khoom siv hluav taws xob LED suav nrog kev hloov pauv, ib qho inductor, cov khoom siv hloov pauv (MOSfet), cov lus tawm tswv yim, cov khoom siv lim tawm, cov khoom siv lim tawm, thiab lwm yam. Raws li lub sijhawm sib txawv, yuav tsum muaj cov khoom siv hluav taws xob tiv thaiv hluav taws xob, cov khoom siv hluav taws xob tiv thaiv hluav taws xob, LED qhib hluav taws xob tiv thaiv, tiv thaiv overcurrent thiab lwm yam circuits.
2, LED tsav lub zog nta
(1) Kev ntseeg siab tshwj xeeb tshwj xeeb zoo li lub zog tsav ntawm LED txoj kev teeb, nws tau teeb tsa ntawm qhov siab siab, nws tsis yooj yim rau kev tswj hwm, thiab tus nqi tu kuj tseem loj.
(2) Kev ua haujlwm siab LED yog cov khoom siv txuag hluav taws xob, thiab kev ua haujlwm ntawm kev tsav tsheb fais fab yog siab. Nws yog ib qho tseem ceeb heev kom dissipate cua sov los ntawm lub hwj chim mov ntsia nyob rau hauv lub fixture. Lub zog hluav taws xob muaj kev ua haujlwm siab, nws lub zog siv me me, thiab cov cua sov tsim hauv lub teeb me me, uas txo qhov kub ntawm lub teeb. Nws yog qhov zoo los ncua lub teeb lwj ntawm LEDs.
(3) Txoj kev tsav tsheb
Muaj ob hom kev khiav tsheb: ib qho yog qhov hluav taws xob tsis tu ncua rau ntau qhov chaw tam sim no, thiab txhua qhov chaw tam sim no muab lub zog rau txhua qhov LED cais. Ua li no, kev sib xyaw ua ke yog hloov tau, thiab tag nrho cov teeb meem LED tsis cuam tshuam rau kev ua haujlwm ntawm lwm cov LEDs, tab sis tus nqi yuav siab dua me ntsis. Lwm qhov yog cov khoom siv hluav taws xob tsis tu ncua tam sim no, uas yog hom tsav tsheb tau txais los ntawm "Zhongke Huibao". LEDs yog ua nyob rau hauv series los yog nyob rau hauv parallel. Nws qhov zoo dua yog tias tus nqi qis dua, tab sis qhov kev hloov pauv tsis zoo, thiab nws yog ib qho tsim nyog los daws qhov teeb meem ntawm LED tsis cuam tshuam rau lwm cov LEDs.
(4) Surge tiv thaiv
Lub peev xwm ntawm LEDs los tiv thaiv kev kub ntxhov yog qhov tsis zoo, tshwj xeeb tshaj yog tiv thaiv kev rov qab muaj peev xwm. Nws tseem yog ib qho tseem ceeb los txhawb kev tiv thaiv hauv cheeb tsam no. Qee lub teeb LED tau teeb tsa sab nraum zoov, xws li LED txoj kev teeb. Vim yog qhov pib ntawm daim phiaj thauj khoom thiab qhov cuam tshuam ntawm xob laim, ntau qhov surges yuav raug cuam tshuam los ntawm kab sib chaws, thiab qee qhov surges yuav ua rau LED puas. Yog li ntawd, kev tsom xam ntawm "Zhongke Huibao" tsav lub zog yuav tsum muaj qee yam tsis muaj kev tiv thaiv kev tiv thaiv, thiab vim tias cov khoom siv hluav taws xob thiab cov teeb tau hloov tas li, LED tsav lub zog yuav tsum muaj peev xwm tiv thaiv kev cuam tshuam ntawm kev nce siab thiab tiv thaiv. LED los ntawm kev puas tsuaj.
(5) Kev tiv thaiv muaj nuj nqi
Ntxiv nrog rau qhov kev tiv thaiv ib puag ncig, lub zog hluav taws xob zoo dua tuaj yeem ua rau LED qhov kub thiab txias tawm tswv yim tsis tu ncua ntawm cov zis tam sim no los tiv thaiv qhov kub ntawm LED los ntawm siab dhau; nws yuav tsum tau ua kom tau raws li qhov kev nyab xeeb thiab electromagnetic compatibility.
