RauLED teeb- emitting chips, siv tib lub thev naus laus zis, lub zog ntawm ib lub LED ntau dua, qhov kev ua haujlwm ntawm lub teeb qis dua, tab sis nws tuaj yeem txo tus naj npawb ntawm cov teeb siv, uas yog qhov zoo rau kev txuag nqi; Qhov me dua lub zog ntawm ib qho LED, qhov ntau dua qhov kev ua haujlwm luminous. Txawm li cas los xij, tus naj npawb ntawm LEDs yuav tsum 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 yuav muaj kev cuam tshuam tsis zoo rau lub teeb faib nkhaus. Raws li cov ntsiab lus tseem ceeb, LED nrog ib qho kev ntsuas ua haujlwm tam sim no ntawm 350mA thiab lub zog ntawm 1W feem ntau yog siv.

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

Raws li qhov tam sim no kev ua tau zoo ntawm kev lag luam muaj kev txhawj xeeb, yog tias lub luminous flux ntawm LED lub teeb qhov chaw xav kom ncav cuag cov kev xav tau ntawm ntau txhiab lossis kaum tawm txhiab lumens, ib qho LED nti tsis tuaj yeem ua tiav. Txhawm rau ua kom tau raws li qhov xav tau ntawm cov teeb pom kev zoo, lub teeb ci ntawm ntau lub teeb ci LED tau muab tso rau hauv ib lub teeb kom tau raws li lub teeb pom kev zoo. Lub hom phiaj ntawm kev ci ntsa iab siab tuaj yeem ua tiav los ntawm kev txhim kho lub luminous efficiency ntawm LED, siv cov khoom ntim siab luminous efficiency thiab siab tam sim no los ntawm ntau lub nti loj.

Muaj ob txoj hauv kev tseem ceeb ntawm cov cua sov dissipation rau LED chips, uas yog cov cua sov conduction thiab cua sov convection. Lub tshav kub dissipation qauv ntawmLED teebmuaj xws li lub hauv paus kub dab dej thiab radiator. Lub phaj soaking tuaj yeem paub txog ultra-high tshav kub flux hloov hluav taws xob thiab daws qhov teeb meem kub dissipation ntawmhigh-power LED. Lub phaj nqus dej yog lub tshuab nqus tsev nrog micro-qauv ntawm 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 cov kab noj hniav yuav ua rau cov phenomenon ntawm cov kua theem gasification nyob rau hauv lub qis lub tshuab nqus tsev ib puag ncig. Lub sijhawm no, qhov nruab nrab absorbs cua sov thiab lub ntim nthuav dav sai, thiab cov pa roj theem nruab nrab yuav sai sai ua rau tag nrho cov kab noj hniav. Thaum cov roj-theem nruab nrab tiv tauj ib qho chaw txias, condensation yuav tshwm sim, tso tawm cov cua sov thaum lub sij hawm evaporation, thiab cov condensed kua nruab nrab yuav rov qab mus rau lub evaporation tshav kub qhov chaw ntawm lub microstructure.

Cov kev siv hluav taws xob siab tshaj plaws ntawm LED chips yog: nti o, txhim kho luminous efficiency, ntim nrog lub teeb pom kev zoo, thiab tam sim no loj. Txawm hais tias tus nqi ntawm cov luminescence tam sim no yuav nce proportionally, tus nqi ntawm cov cua sov kuj yuav nce. Kev siv cov thermal conductivity ceramic lossis hlau resin ntim cov qauv tuaj yeem daws qhov teeb meem kub ntxhov thiab ntxiv dag zog rau cov yam ntxwv ntawm cov khoom siv hluav taws xob, kho qhov muag thiab thermal. Txhawm rau txhim kho lub zog ntawm LED teeb, kev ua haujlwm tam sim no ntawm LED chips tuaj yeem nce ntxiv. Txoj hauv kev ncaj qha los ua kom qhov ua haujlwm tam sim no yog txhawm rau nce qhov loj ntawm LED chips. Txawm li cas los xij, vim qhov nce ntawm kev ua haujlwm tam sim no, cov cua sov dissipation tau dhau los ua qhov teeb meem tseem ceeb. Kev txhim kho ntawm txoj kev ntim khoom ntawm LED chips tuaj yeem daws qhov teeb meem kub dissipation.
