RauLED teeb-emitting chips, siv tib lub thev naus laus zis, qhov siab dua lub zog ntawm ib qho LED, qhov qis dua lub teeb pom kev zoo. Txawm li cas los xij, nws tuaj yeem txo cov roj teeb uas siv tau, uas yog qhov zoo rau kev txuag nqi; Lub zog me me ntawm ib qho LED, lub teeb ua haujlwm ntau dua. Txawm li cas los xij, raws li tus naj npawb ntawm LEDs xav tau nyob rau hauv txhua lub teeb nce, qhov loj ntawm lub teeb lub cev nce, thiab tsim teeb meem ntawm lub lens optical nce, uas tuaj yeem muaj kev cuam tshuam tsis zoo rau lub teeb faib nkhaus. Raws li cov ntsiab lus tseem ceeb, ib qho LED nrog cov ntsuas ua haujlwm tam sim no ntawm 350mA thiab lub zog ntawm 1W feem ntau yog siv.

Nyob rau tib lub sijhawm, cov tshuab ntim khoom kuj tseem yog qhov tseem ceeb uas cuam tshuam rau lub teeb pom kev zoo ntawm LED chips, thiab cov thermal tsis kam ntawm LED teeb pom kev ncaj qha cuam tshuam txog qib ntawm ntim tshuab. Qhov zoo dua cov cua kub dissipation technology, qhov qis thermal kuj, qhov me me lub teeb attenuation, lub brightness ntawm lub teeb ntau dua, thiab ntev nws lifespan.

Hais txog kev ua tiav thev naus laus zis tam sim no, nws tsis tuaj yeem ua rau ib qho LED nti kom ua tiav qhov xav tau luminous flux ntawm ntau txhiab lossis txawm kaum txhiab ntawm lumens rau LED qhov chaw. Txhawm rau ua kom tau raws li qhov xav tau ntawm lub teeb pom kev zoo tag nrho, ntau lub teeb ci LED tau muab tso rau hauv ib lub teeb kom tau raws li qhov xav tau ntawm lub teeb pom kev zoo. Los ntawm scaling li ntau chips, txhim khoLED luminous efficiency, adopting high light efficiency ntim, thiab siab tam sim no hloov dua siab tshiab, lub hom phiaj ntawm high brightness yuav ua tau tiav.

Muaj ob txoj hauv kev txias txias rau LED chips, uas yog thermal conduction thiab thermal convection. Lub tshav kub dissipation qauv ntawmLED teeb pom kev zooCov khoom siv muaj xws li lub hauv paus cua sov dab dej thiab lub dab dej kub. Lub phaj nqus dej tuaj yeem ua tiav cov cua kub kub siab heev ntawm qhov kub thiab txias thiab daws qhov teeb meem kub dissipation ntawm high-power LEDs. Lub phaj nqus dej yog lub tshuab nqus tsev nrog lub microstructure ntawm nws sab hauv phab ntsa. Thaum tshav kub hloov los ntawm lub tshav kub mus rau qhov chaw evaporation, qhov nruab nrab ua hauj lwm nyob rau hauv lub chamber undergoes kua-theem gasification nyob rau hauv ib tug tsawg lub tshuab nqus tsev ib puag ncig. Nyob rau lub sijhawm no, qhov nruab nrab absorbs cua sov thiab nthuav dav hauv ntim, thiab cov roj-theem nruab nrab sai sai puv tag nrho cov chamber. Thaum cov roj-theem nruab nrab los rau hauv kev sib cuag nrog ib qho chaw txias, condensation tshwm sim, tso cov cua sov uas tau sau tseg thaum evaporation. Lub condensed kua theem nruab nrab yuav rov qab los ntawm microstructure mus rau evaporation tshav kub qhov chaw.

Txoj kev siv hluav taws xob ntau rau LED chips yog: nti scaling, txhim kho luminous efficiency, siv lub teeb pom kev zoo ntim, thiab kev hloov siab tam sim no. Txawm hais tias tus nqi ntawm tam sim no tawm los ntawm txoj kev no yuav nce proportionally, tus nqi ntawm cov cua sov generated kuj yuav nce raws li. Hloov mus rau lub siab thermal conductivity ceramic los yog hlau resin ntim qauv tuaj yeem daws qhov teeb meem ntawm cov cua sov thiab txhim kho cov khoom siv hluav taws xob qub, kho qhov muag, thiab cov yam ntxwv thermal. Txhawm rau nce lub zog ntawm LED teeb pom kev zoo, qhov ua haujlwm tam sim no ntawm LED nti tuaj yeem nce ntxiv. Txoj kev ncaj qha los ua kom qhov ua haujlwm tam sim no yog ua kom qhov loj ntawm LED nti. Txawm li cas los xij, vim qhov nce hauv kev ua haujlwm tam sim no, cov cua sov dissipation tau dhau los ua qhov teeb meem tseem ceeb, thiab kev txhim kho hauv cov ntim ntawm LED chips tuaj yeem daws qhov teeb meem kub dissipation.
