Peb yam ntawm LED txoj kev teeb cua sov dissipation
Los ntawm kev siv tswv yim, nws tau pom tias lub zog loj LED txoj kev teeb pom kev zoo muaj qhov zoo ntawm kev txuag hluav taws xob, kev tiv thaiv ib puag ncig, lub neej ntev, kho qhov ci ci thiab xim kub, thiab cov xim zoo nkauj. Nrog rau kev loj hlob ntawm LED thev naus laus zis thiab kev txhim kho txuas ntxiv ntawm kev ua haujlwm, LED teeb pom kev zoo-xeev yog qhov sib txawv thiab kev daws teeb meem zoo tshaj plaws rau kev txuag hluav taws xob. Lub zog txuag cov yam ntxwv ntawm LED txoj kev teeb lub teeb pom kev zoo yog txiav txim siab los ntawm LED nti thiab lub zog hluav taws xob. Txawm li cas los xij, LED nti thiab lub zog module tau sib xyaw ua ke, thiab qhov chaw feem ntau me me thiab cov cua sov dissipation tsis zoo. LED nti thiab cov khoom siv hluav taws xob yog cov khoom cua sov, uas ua rau qhov kub thiab txias siab dua. Yog li ntawd, tsab xov xwm no yuav txo tau qhov kub thiab txias ambient los ntawm kev txhim kho cov cua kub dissipation tej yam kev mob ntawm lub LED txoj kev teeb system, ua kom lub luminous efficiency ntawm lub LED thiab lub efficiency ntawm lub hwj chim mov, thiaj li hais tias lub LED fais fab mov thiab lub neej ntawm LED nti yuav ua tau. yuav tsum sib phim, thiab kev txuag hluav taws xob tiag tiag, kev tiv thaiv ib puag ncig thiab lub neej ntev tuaj yeem ua tiav.
Cia's tham txog peb yam tseem ceeb ntawm cov ntsiab lus tshawb fawb:
1. Kev sim kev tshawb fawb txog cov thermoelectric kev sib raug zoo ntawm high-power LED txoj kev teeb. Siv lub zog hluav taws xob LED txoj kev teeb pom kev zoo nrog hom kev sib txuas ua ntej hauv koob thiab tom qab ntawd ua tib yam li cov khoom, qhov kev sim tshawb fawb txog kev sib raug zoo ntawm lub hwj chim faib thiab qhov kub thiab txias faib nyob rau hauv ob hom kev siv hluav taws xob tam sim no thiab qhov hluav taws xob tsis tu ncua. Tsim kom muaj kev sim platform rau kev tshawb fawb txog kev sib raug zoo ntawm thermoelectric ntawm LED txoj kev teeb thiab tshuaj xyuas qhov kev sim. Los ntawm cov txiaj ntsig, nws paub tias nyob rau hauv qhov xwm txheej tam sim no, muaj kev sib raug zoo ntawm kev sib txuas ntawm LED qhov kub thiab qhov hluav taws xob rau pem hauv ntej, uas txheeb xyuas cov yam ntxwv ntawm qhov hluav taws xob poob ntawm LED, thiab koj tuaj yeem sim ntsuas qhov sib txuas ntawm qhov kub thiab txias. LED nrog ib tug loj tam sim no, uas txawv ntawm cov tsoos me me tam sim no ntsuas. . Piv nrog rau qhov tsis tu ncua voltage tsav, tag nrho cov zis hluav taws xob ntawm lub zog hluav taws xob yog qhov ruaj khov dua nyob rau hauv qhov tsav tam sim no. Txawm li cas los xij, vim qhov ntsuas kub tsis sib xws ntawm ntau lub LEDs, cov khoom siv hluav taws xob sib txuas yog txwv los ntawm ib leeg. Tsim ib lub voj voog vicious. Yog li ntawd, kev tsim cov cua kub dissipation tshuav nyiaj li cas yog qhov tseem ceeb heev rau kev txhim kho tag nrho qhov zoo ntawm high-power LED txoj kev teeb.
2. Optimized tsim ntawm high-power LED txoj kev teeb radiator. Noj ib lub tuam txhab 150W high-power LED txoj kev teeb raws li cov khoom siv tshawb fawb, thermal resistance network qauv ntawm profile radiator yog tsim, thiab lub radiator ua tau raws li qhov yuav tsum tau ua kom sov dissipation yog theoretically tsim. Rau lub hauv paus no, Icepak thermal tsom xam software yog siv los txhim kho qhov tsim. Qhov laj thawj ntawm kev tsim hluav taws xob uas twb muaj lawm raug txheeb xyuas, thiab cov txiaj ntsig theoretical suav nrog cov txiaj ntsig tau zoo, qhia tias kev suav theoretical yog ib feem tseem ceeb ntawm kev tsim hluav taws xob. Kev sib txuas software optimization tuaj yeem txo R& D nqi, txo R& D cycles, thiab txhim kho R& D efficiency.
3. High-power LED txoj kev teeb lub zog module tshav kub dissipation tsim. Raws li kev tsim ntawm high-power LED fais fab mov Circuit Court, lub tshav kub khiav txoj kev thiab lwm yam thermal kuj raug soj ntsuam, thiab lub shortest tshav kub khiav txoj kev yog coj raws li lub hom phiaj, ob lub hwj chim txias li yog tsim structurally. Lub hom phiaj ntawm qhov chaw nqaim rau cov cua sov dissipation ntawm lub hwj huam mov, cov yeeb nkab hluav taws xob me me tau sim siv rau cov cua kub dissipation ntawm LED fais fab module. Cov txiaj ntsig tau pom tias ob lub tswv yim tuaj yeem ua tau raws li cov qauv tsim thermal ntawm cov khoom siv hluav taws xob, thiab cov khoom siv hluav taws xob ua kom sov ntawm cov khoom siv hluav taws xob micro cua sov yog li 5 ℃ zoo dua li lwm cov tswv yim.
