LED Txoj Kev Teeb Teeb Thaum Tshav Kub Dissipation Teeb meem

Peb paub tias cov teeb pom kev zoo ntawm cov teeb pom kev zoo muaj qhov xav tau ntau dua rau kev ci ntsa iab thiab kev tsim hluav taws xob ntau dua, yog li qhov teeb meem kub ntxhov tau ib txwm yog qhov teeb meem tseem ceeb uas cov tuam txhab teeb pom kev zoo yuav tsum tau daws. Txawm li cas los xij, nrog kev txhim kho txuas ntxiv ntawm thev naus laus zis, qhov teeb meem kub ntxhov ntawm LED txoj kev teeb kuj tseem txhim kho tas li. Cia peb saib yuav ua li cas txoj kev teeb pom kev zoo nrog cov teeb meem kub dissipation ntawm LED txoj kev teeb.

 

LED txoj kev teeb yog siv sab nraum zoov, yog li lawv muaj kev nruj ib puag ncig. Piv txwv li, tsis zoo cua sov dissipation ncaj qha ua rau kev laus sai ntawm LEDs, txo stability, thiab txo lifespan.

Cia peb ua piv txwv. Yog hais tias lub photoelectric conversion efficiency ntawm 10W dawb LED yog 20 feem pua, ces 8W ntawm hluav taws xob lub zog yuav hloov mus rau hauv tshav kub. Yog tias tsis muaj kev ntsuas kub dissipation, qhov tseem ceeb ntawm lub zog hluav taws xob LEDs yuav nce sai heev. Thaum nws qhov kub thiab txias (TJ) nce mus rau qhov ntsuas kub siab dua (feem ntau yog 150 degree), lub zog hluav taws xob LED yuav raug puas vim overheating.

 

Tam sim no, cov txheej txheem kub dissipation tseem ceeb ntawm kev ua lag luam yog yuam kom cov cua sov dissipation los ntawm kev ntxiv cov kiv cua, cov kav dej kub, cov kav dej kub thiab cov phaj kub sib npaug. Nyob rau hauv qhov chaw tseem ceeb ntawm cov cua sov dissipation, cov tuam txhab teeb pom kev zoo siv cov phiaj xwm hluav taws xob los tsim lub teeb vaj tsev nyob rau hauv lub tshuab hluav taws xob los pab LED txoj kev teeb pom kev zoo dissipate cua sov.

Kev nkag siab me ntsis ntawm txoj kev teeb pom kev zoo, koj paub tias tus nqi ntawm cov teeb pom kev hauv khw txawv heev. Yog tias koj nkag siab txog kev lag luam coj txoj kev teeb me ntsis, koj yuav pom tias tus nqi sib txawv ntawm cov teeb pom kev zoo yog qhov loj heev. Yog tias tib lub teeb pom kev zoo sib txawv, tus nqi yuav txawv heev.

 

Ua ntej tshaj plaws, qhov zoo ntawm LED nti: Peb txhua tus paub tias lub nti muaj kev cuam tshuam zoo rau tus nqi ntawm LED txoj kev teeb. Siv nti loj los ntawm 7 * 9mil rau 10 * 23mil raws li kev siv. Qhov loj dua qhov loj, qhov kim dua tus nqi txheeb ze thiab qhov zoo dua. Ntau hom kev teeb pom kev sib txawv siv cov chips sib txawv, thiab tau kawg tus nqi yuav txawv.

 

Qhov thib ob, qhov ci ntsa iab kuj yog ib qho ntawm cov yam ntxwv uas cuam tshuam rau tus nqi ntawm cov teeb pom kev zoo. Qhov tseeb, nyob rau hauv kev siv cov khoom siv teeb pom kev zoo LED, peb kuj tuaj yeem pom tias cov khoom kim heev LED teeb pom kev zoo yog mos thiab tsis dazzling, thaum cov khoom pheej yig LED teeb pom kev zoo yog xim dawb thiab ci heev, thiab kev siv mus sij hawm ntev tsis zoo rau lub teeb pom kev zoo. qhov muag.

 

Tsis tas li ntawd, txawm tias cov teeb pom kev sib txawv ntawm tib hom LED txoj kev teeb siv cov profiles sib txawv, LED teeb nyob rau hauv kev ua lag luam yeej muaj ob qhov profile: semi-yas thiab semi-aluminium raj thiab tag nrho-yas teeb. Lub raj yas tag nrho zam qhov teeb meem ntawm hluav taws xob poob siab, tab sis qhov teeb meem loj dua yog cov cua sov dissipation. Vim tias tag nrho cov cua sov tau ntim rau hauv lub raj, nws tsis tuaj yeem dissipated tag nrho, thiab lub teeb lwj yog qhov hnyav heev, yog li nws tsis pom zoo. Tus nqi kuj pheej yig.

 

Tsis tas li ntawd, cov khoom ntawm semi-yas thiab semi-aluminium raj yog tsuas yog los txiav txim siab lub thickness ntawm txhuas, thiab cov cua kub dissipation nyhuv yuav tsum yog tsawg kawg yog 1.0mm kom ncav cuag tus qauv. Tam sim no, cov qauv ntawm qee lub chaw tsim khoom yog qhov pib 0.6-0.8MM tuab, thiab cov txhuas yog xim sub-xim, uas ua pov thawj tias muaj cov impurities ntau dua. Tus nqi ntawm txoj kev teeb yog pheej yig dua li ob, thiab kev ruaj ntseg zoo yog kim dua.
