Tam sim no, muaj ob hom kev sib tham ntawm lub teeb rau LED teeb, ib qho yog txhuas txheej, thiab lwm yam yog iav laug cam. Tom ntej no, Kuv yuav tshuaj xyuas qhov sib txawv ntawm aluminium substrate ntawm LED teeb thiab lub rooj tsav tsheb fiberglass rau koj.
Ua ntej, cia' nthuav qhia cov iav fiberglass: txhawm rau kom tau txais qhov txiaj ntsig zoo hauv tus nqi, qee cov tuam ntxhab siv iav brazing board ua lub rooj tsav xwm PCB rau teeb LED. Raws li cov ntaub ntawv sib txawv thiab cov txheej txheem tsim khoom, cov iav fiberglass tuaj yeem muab faib ua cov iav fiberglass, ob npaug ntawm ob sab tooj liab ntawv ci cov laug cam, perforated iav tooj liab ntawv ci fiberglass laug cam, thiab ib leeg-mog tooj liab tooj liab ntawv ci fiberglass laug cam.
Vim yog cov xwm txheej no, tus nqi ntawm cov raj LED yuav cuam tshuam ncaj qha. Kuj tseem muaj txoj hauv kev txuag tus nqi ntawm kev siv cua sov ua kom sov, uas yog kom ncaj qha teeb tsa lub Circuit Court ntawm iav phaj phaj. Cov raj LED ua los ntawm cov phiaj xwm saum toj no yuav raug nqi ntau dua li cov txheej txheem txhuas hauv nqe, tab sis cov cua sov ua kom tsis zoo li zoo li ntawm cov txheej txheem txhuas. Lossis koj tuaj yeem tshawb xyuas seb cov khoom twg zoo dua rau cov tshuab hluav taws xob LED
Aluminium substrate: Los ntawm cov qauv tsim khoom, nws tuaj yeem faib ua peb txheej, sab saum toj yog txheej txheej txheej txheej, nruab nrab yog txheej txheej cua sov thiab txheej rwb thaiv tsev, thiab hauv qab yog txheej txheej txhuas txheej. Tam sim no, feem ntau LED T8 raj siv hom kev sib tham ntawm lub rooj tsavxwm.
Cov txheej txheem txheej txheem txheej txheem feem ntau siv cov ntawv ci tooj liab ua cov khoom siv hluav taws xob. Cov tooj liab ua tau zoo heev, tab sis tus nqi tooj liab kuj tseem kim heev. Yuav kom txuag tau qee tus nqi, qee cov tuam ntxhab ua rau cov ntawv tooj liab nyias nyias, yog li kev ua haujlwm kuj tseem cuam tshuam. Tus nqi ntawm cov thermal thiab insulating txheej sib txawv heev vim cov khoom sib txawv. Yog tias koj xav kom muaj cov cua sov zoo heev thiab rwb thaiv tsev, koj tuaj yeem siv cov khoom siv tshwj xeeb ceramic, tab sis cov khoom siv no kim heev, thiab nws nyuaj rau ntau lub tuam txhab tsim khoom lees txais nws.
Yog li lawv tab tom nrhiav lwm cov ntaub ntawv pheej yig los txo tus nqi, piv txwv li epoxy cob thiab iav ntaub feem ntau siv. Aluminium puag txheej tuaj yeem ua los ntawm phaj tooj liab thiab phaj txhuas. Cov cua sov ua kom sov ntawm cov phaj tooj liab yog qhov zoo heev, thiab tus nqi yuav siab heev. Yog li ntawd, txhuas daim hlau feem ntau siv los ua cov txheej txheem txhuas. Qhov yuav tsum tau ua yog daim hlau txhuas yuav tsum muaj cua sov zoo thiab tsis tuaj yeem khoov tau yooj yim.
Hauv kev xaus, qhov yeeb ncuab loj tshaj plaws ntawm LED yog cua sov ua kom sov, yog li nws yuav tsum yog txheej txheej nrog cov cua sov sib kis tau zoo, uas ua kom sov sai thiab ua kom sov sai. Aluminium substrate yog qhov zoo thiab cua sov yog qhov zoo; tab sis tus nqi ntawm aluminium substrate yog kim dua li lub rooj tsav tsheb fiberglass, thiab cov teeb LED xav tau Cov cua sov kom txaus kom ntseeg tau qhov ua tau zoo. Yog li aluminium substrate yog thawj qhov kev xaiv.
