High-power LED txoj kev teeb yuav siv tau nyob rau hauv ntau yam engineering kev tsim kho, tab sis vim yog tshav kub dissipation txwv, high-power LED txoj kev teeb tsuas yog siv nyob rau hauv ib tug tsawg ib puag ncig tom qab lawv tsim. Ntawm cov thev naus laus zis tseem ceeb rau LED txoj kev teeb pom kev zoo, kev tsim hluav taws xob tawg yog qhov txuas tseem ceeb heev kuj yog ib qho ntawm cov kev txwv tsis pub siv dav. Qhov zoo ntawm kev tsim hluav taws xob hluav taws xob yuav ncaj qha txiav txim siab qhov ua tau zoo ntawm LED txoj kev teeb pom kev zoo thiab seb qhov kev nce qib thiab daim ntawv thov tiag tiag tuaj yeem ua tiav. Tam sim no, cov thev naus laus zis hluav taws xob hluav taws xob ntawm LED txoj kev teeb feem ntau siv cov txheej txheem hluav taws xob ua hluav taws xob, uas yog 5 hli tuab tooj liab phaj, uas yog qhov ntsuas kub sib npaug, tab sis qhov hnyav dhau lawm. Qhov hnyav yog qhov tseem ceeb heev hauv txoj kev teeb pom kev zoo, vim tias txoj kev teeb pom kev siab yog 9 meters siab, yog tias hnyav dhau lawm, kev phom sij yuav nce ntxiv, tshwj xeeb tshaj yog thaum muaj cua daj cua dub thiab av qeeg, kev sib tsoo yuav tshwm sim. Tej zaum yav tom ntej, tom qab LED dav nkag mus rau hauv txoj kev teeb chaw, modularized tshav kub dissipation yuav zoo dua daws cov teeb meem ntawm LED txoj kev teeb hluav taws xob dissipation.
1: Kev sib raug zoo ntawm LED hlws ris kub thiab luminous flux thiab lub neej. Raws li cov yam ntxwv ua haujlwm ntawm high-power LEDs, qhov sib txuas kub yog ncaj qha ntsig txog qhov loj ntawm luminous flux thiab qhov ntev ntawm kev pab cuam lub neej. Thawj qhov kub dissipation tsim ntawm LED pob yog txiav txim los ntawm cov txheej txheem nyob rau hauv lub LED ntau lawm theem. Nws yog tsuas yog tsim los ntawm cov thermal tsim ntawm lub nti thiab thermal tsim ntawm lub pob. Los ntawm kev tsim qauv tsim nyog thiab tsim nyog, kev ua haujlwm zoo ntawm LED hluav taws xob thiab hluav taws xob cuam tshuam tuaj yeem tau txais.
2: Cov txheej txheem hluav taws xob thib ob ntawm LED. Rau cov high-power LED uas tau ua lag luam, thawj cov cua kub dissipation tsim tsim los ntawm nws cov nti pob tau raug kho thiab tsis tuaj yeem hloov pauv thaum siv, yog li nws yog siv los ua lub teeb ci hauv txoj kev teeb. Yog tias qhov kev xav tau ntawm cov cua kub dissipation tuaj yeem ua tiav, cov txiaj ntsig yuav raug tso tawm ncaj qha. Yog tias qhov kev xav tau ntawm cov cua sov ntawm cov LEDs tsis tuaj yeem ua tau raws li qhov yuav tsum tau ua, kev tsim lub dab dej kub yuav tsum tau ua. Tom qab ntawd, txhawm rau saib seb tus qauv tsim puas tuaj yeem ua tau raws li qhov xav tau ntawm cov cua kub dissipation ntawm LEDs, cov kauj ruam tom ntej ntawm kev tsim kho kom zoo yog xav tau, yog tias tsis yog, nws yog qhov tsim nyog. Rov tsim lub radiator kom txog thaum nws tuaj yeem ua tau raws li qhov yuav tsum tau ua.
3: LED theem nrab cua sov dissipation tsim txheej txheem, suav cov thermal resistance thiab junction kub kom pom seb cov cua sov dissipation ntawm LED tuaj yeem ua tau raws li qhov xav tau ntawm cov cua sov dissipation, cov txiaj ntsig yuav raug tso tawm ncaj qha, yog tias cov cua sov dissipation tuaj yeem ua tau raws li qhov xav tau. Cov kev xav tau ntawm LED tsis tuaj yeem ua tau raws li qhov xav tau, kev tsim lub dab dej kub yuav tsum tau ua. Nws yog ib qho tsim nyog los ua qhov kev tsim kho kom zoo ntxiv tom ntej, yog tias tsis yog, nws yuav tsum rov tsim lub tshuab hluav taws xob kom txog thaum nws tuaj yeem ua tau raws li qhov yuav tsum tau ua.
4: Lub cheeb tsam ntawm cov fins radiating yog teem rau ntawm lub siab nyiam. Kev teeb tsa ntawm cov hluav taws xob hluav taws xob ntawm lub teeb tsis suav nrog kev siv lub teeb, uas cuam tshuam rau cov nyhuv ntawm cov fins. Tsis quav ntsej convection tshav kub dissipation. Txawm hais tias ntau tus neeg tsim khoom xav txog ntau yam kev ntsuas: cov kav dej kub, lub voj voog cov kav dej kub, ntxiv cov roj thermal, thiab lwm yam, lawv tsis paub tias thaum kawg cov cua sov yuav dissipated los ntawm sab nrauv ntawm lub teeb. Yog tias qhov kub thiab txias ntawm cov fins yog qhov tsis sib xws, nws yuav ua rau qee qhov ntawm cov fins (qhov uas muaj qhov kub thiab txias) tsis muaj kev cuam tshuam lossis muaj kev txwv.
