Nyob rau lub caij nplooj ntoos hlav thiab lub caij ntuj sov ntawm lub xyoo, sab nraum zoov LED cov ntxaij vab tshaus yog qhov nyuaj tshaj plaws. Cov huab cua ntub thiab kub kub ua rau LED cov ntxaij vab tshaus ntsib qhov kev tsis sib haum xeeb ntawm kev ya raws thiab cua kub dissipation. Yuav ua li cas thiaj ua tau txoj haujlwm zoo ntawm kev tiv thaiv cov dej noo hauv cov huab cua los nag thaum tswj kom zoo cua sov dissipation nyob rau hauv qhov kub thiab txias ib puag ncig tau dhau los ua ib qho teeb meem pos rau sab nraum zoov LED zaub.
1. Moisture-proof thiab tshav kub-dissipation, ib khub ntawm natural contradictions
Cov khoom siv sab hauv ntawm LED zaub yog MSD cov khoom (cov av noo rhiab heev). Thaum noo noo nkag mus, nws yuav ua rau oxidation thiab corrosion ntawm lub teeb hlaws, PCB board, fais fab mov, fais fab qaum thiab lwm yam khoom, uas yuav ua rau tuag lub teeb tsis ua hauj lwm. Yog li ntawd, lub module, sab hauv thiab sab nraud chassis ntawm LED npo yuav tsum tau kom huv si thiab nruj nreem ya raws-pov thawj thiab waterproof.
Nyob rau tib lub sijhawm, cov khoom siv sab hauv ntawm lub vijtsam puv xim LED kuj yog cov khoom siv hluav taws xob ntau tshaj plaws, xws li LED teeb hlaws, tsav ICs, thiab hloov cov khoom siv hluav taws xob. 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 dissipated, nws yuav ua rau cov khoom siv sab hauv ntawm LED kom sov thiab puas, ua rau muaj kev ua haujlwm tsis zoo. Yog li ntawd, zoo tshav kub dissipation yuav tsum tau ib tug pob tshab thiab convective qauv, uas contradicts qhov yuav tsum tau ntawm noo noo kuj.
2. Yuav ua li cas tiv thaiv ya raws thiab cua sov dissipation ntawm LED zaub?
Qhov kub thiab av noo, yuav ua li cas rau ob txoj kev
Nyob rau hauv huab cua kub thiab av noo, 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 cov qauv tsim tsim.
(1) Txo kev siv hluav taws xob thiab txo cov cua sov yog txoj hauv kev zoo los txhim kho cov cua sov. Lianjian Optoelectronics xaiv cov khoom siv zoo LED los ntawm lub hauv paus los ua kom zoo rau kev tsim, tsom mus rau kev tshawb fawb ywj pheej thiab kev txhim kho ntawm kev ua haujlwm siab thiab lub zog tsav zoo. Qhov zoo tshaj plaws ntawm cov khoom siv raw thiab cov kev ua haujlwm zoo heev tau tsim lub hauv paus ruaj khov rau cov cua sov dissipation thiab noo noo tsis kam.
(2) Kev txhim kho cov txheej txheem tsim khoom yog qhov tseem ceeb tshaj plaws. Nws tau nkag siab tias cov qauv ntawm cov khoom siv hluav taws xob ntawm PCB pawg thawj coj tau ua kom zoo dua qub, qhov nyuaj yog qhov yooj yim, thiab kev teeb tsa yog qhov tsim nyog, thiab cov khoom siv thermal conductivity yog siv rau potting thiab sealing, thaum ntsib seamless nkag ntawm dej vapor. thiab cov cua kub dissipation yuav tsum tau ntawm cov khoom.
(3) Tsim nyog ua kom zoo dua lub thawv qauv, uas tuaj yeem ua lub luag haujlwm tseem ceeb. Xav txog cov cua kub dissipation thiab oxidation tsis kam ntawm cov khoom siv chassis, xaiv cov aluminium zoo. Sab hauv ntawm lub chassis txais cov txheej txheem ntau txheej los tsim cov qauv pob tshab thiab convective tshav kub dissipation, uas tuaj yeem siv tag nrho cov huab cua hauv huab cua rau convection tshav kub dissipation, uas yuav siv sij hawm rau hauv tus account ob lub tshav kub dissipation thiab sealing. , Nws kuj txhim kho kev ntseeg siab thiab kev pabcuam lub neej.
Muaj ib lo lus qub hais tias: "Lub caij ntuj sov me me thiab cua sov loj, chav nce thiab nqis." Cov kab lus no tau hais txog kev nyab xeeb ntawm lub hnub ci lub sij hawm hauv Xiaoshu. Txawm hais tias nyob rau hauv lub ntsej muag ntawm qhov kev ntsuas huab cua hnyav no, LED zaub tseem tuaj yeem tswj tau cov cua sov kom zoo raws li kev ua kom ntseeg tau tias muaj kev ruaj ntseg noo noo, thiab lub vijtsam ua haujlwm zoo li tshiab, ua kom pom lub zog zoo rau lub ntiaj teb sab nraud.
