Qhov sib npaug ntawm cov dej noo thiab cua sov dissipation ntawm sab nraum zoov LED
Humidity thiab kub kub ua rau LED npo ya raws-pov thawj thiab kub-dissipating. Yuav ua li cas kom tsis txhob muaj dej noo nyob rau hauv cov huab cua los nag, thaum tswj kom zoo thaum tshav kub kub dissipation nyob rau hauv ib tug kub kub ib puag ncig, tau dhau los ua ib qho teeb meem nyuaj rau sab nraum zoov LED cov ntxaij vab tshaus.
Moisture thiab tshav kub dissipation, ib khub ntawm ntuj contradictions
LED zaub cov khoom siv sab hauv yog MSD cov khoom (cov khoom siv rhiab heev). Thaum cov dej noo nkag mus, nws yuav ua rau oxidation thiab corrosion ntawm xoom Cheebtsam xws li teeb hlaws, PCB boards, cov khoom siv hluav taws xob, thiab cov hlua hluav taws xob, uas yuav ua rau lub teeb tsis ua haujlwm tuag. Yog li ntawd, cov qauv, cov qauv sab hauv thiab sab nraud chassis ntawm lub vijtsam LED yuav tsum muaj kev qhia dav thiab nruj-pov thawj thiab tsis muaj dej tsim.
Tib lub sijhawm, cov khoom siv sab hauv ntawm LED npo kuj yog cov khoom siv hluav taws xob nrov tshaj plaws, xws li LED teeb hlaws, tsav ICs, hloov khoom siv hluav taws xob, thiab lwm yam. Kev tsim hluav taws xob tsis zoo yuav oxidize cov khoom siv tshuaj ntsuam, cuam tshuam rau qhov zoo thiab lub neej. Yog tias cov cua sov sib sau ua ke thiab tsis tuaj yeem khiav tawm, nws yuav ua rau cov khoom siv sab hauv ntawm LED kom sov thiab puas, uas yuav ua rau tsis ua haujlwm. Yog li ntawd, zoo cua sov dissipation yuav tsum tau ib tug pob tshab thiab convective qauv, uas contradicts qhov yuav tsum tau rau ya raws.
Kub kub, damp cua sov, yuav ua li cas mus cuag ib tug ob-pronged mus kom ze.
Nyob rau hauv huab cua ntub thiab kub, ntsib cov dej noo thiab cua sov dissipation, qhov zoo li tsis sib haum xeeb tsis sib haum xeeb tuaj yeem daws tau los ntawm cov khoom siv zoo tshaj plaws thiab kev tsim qauv zoo.
Ua ntej, txo qis kev siv hluav taws xob thiab txo cov cua sov yog ib txoj hauv kev zoo los txhim kho cov cua sov.
Tsis tas li ntawd, kev txhim kho module ntau lawm technology kuj yog qhov tseem ceeb tshaj plaws.
Thaum kawg, kev ua kom zoo tshaj plaws ntawm lub thawv qauv tuaj yeem ua lub luag haujlwm tseem ceeb. Xav txog lub tshav kub dissipation thiab oxidation tsis kam ntawm cov ntaub ntawv cov ntaub ntawv, xaiv high-zoo txhuas. Sab hauv ntawm rooj plaub siv cov txheej txheem ntau txheej txheej los tsim cov pob tshab tag nrho convection tshav kub dissipation qauv, uas tuaj yeem siv tag nrho cov huab cua ntuj rau convection tshav kub dissipation, coj mus rau hauv tus account ob lub tshav kub dissipation thiab sealing thiab kuj txhim kho kev ntseeg tau thiab kev pab lub neej.
