LED puv xim zaub yuav tsim kom muaj cua sov thaum siv, tshwj xeeb tshaj yog sab nraum zoov, vim nws xav tau kev ci ntsa iab thaum siv, thiab qhov ci yuav tsum siab tshaj 4000CD, yog li nws tsim kom muaj cua sov ntau. Nyob rau hauv cov ntaub ntawv siv, kev txhim kho cov cua kub dissipation kev ua tau zoo ntawm LED tag nrho-xim zaub tuaj yeem tsis tsuas yog txhim kho cov cua kub dissipation efficiency ntawm LED puv xim zaub, tab sis kuj txuag lub zog. Yog li ntawd, lub neej kev pab cuam ntawm LED puv xim zaub yog nce, thiab cov nyhuv ntawm LED tag nrho-xim zaub yog guaranteed.
LED puv xim zaub
Txoj hauv kev los txhim kho cov cua kub dissipation kev ua tau zoo ntawm LED puv xim zaub:
1. Lub tshuab cua txias. Lub neej ntev, kev ua haujlwm siab ntxuam hauv lub teeb vaj tsev txhim kho cov nyhuv tshav kub. Txoj kev no muaj tus nqi qis thiab muaj txiaj ntsig zoo. 2. Lub LED puv xim zaub tau txais cov khoom siv hluav taws xob aluminium, uas yog ntau heev rau cov cua sov dissipation. Kev siv cov cua sov-dissipating aluminium fins ua ib feem ntawm lub chassis ua rau kom sov-dissipating cheeb tsam.
3. High thermal conductivity ceramics yog siv rau cov cua sov dissipation. Lub hom phiaj tseem ceeb ntawm lub teeb lub plhaub rau cov cua kub dissipation yog kom txo cov kev khiav hauj lwm kub ntawm LED high-txhais zaub nti, thiab expansion coefficient ntawm LED nti yog txawv los ntawm peb cov hlau thermal thiab tshav kub dissipation cov ntaub ntawv. LED nti tsis tuaj yeem raug welded ncaj qha, zam kev puas tsuaj ntawm qhov kub thiab txias kev ntxhov siab rau LED tag nrho-xim zaub nti.
4. Thaum tshav kub kub cov yeeb nkab kub dissipation, cov yeeb nkab cua sov dissipation yog siv los tso tawm cov cua sov ntawm LED tag nrho-xim zaub nti rau lub cev kub dab dej.
5. Deg hluav taws xob cua sov dissipation, saum npoo ntawm lub teeb vaj tsev siv hluav taws xob kom dissipate cua sov. Txoj kev yooj yim tshaj plaws yog siv cov xim hluav taws xob kub-dissipating, uas tuaj yeem tso tawm cov cua sov los ntawm qhov chaw ntawm lub teeb ntawm LED puv xim zaub los ntawm hluav taws xob.
6. Thaum lub plhaub yog txhaj tshuaj molded, lub plhaub yas thermal yog ntim nrog cov khoom siv thermally los txhim kho cov cua sov thiab cov cua kub dissipation.
