Qhov kev sib tw loj tshaj plaws rau LED teeb pom kev zoo nyob rau tam sim no yog cua sov dissipation. Tsis zoo cua sov dissipation tau ua rau LED tsav tsheb fais fab mov thiab electrolytic capacitors ua qhov tsis txaus rau kev txhim kho ntxiv ntawm LED teeb pom kev zoo, thiab yog vim li cas rau kev laus ntxov ntxov ntawm LED teeb qhov chaw.
Nyob rau hauv lub teeb pom kev zoo siv LV LED lub teeb qhov chaw, vim lub xeev ua hauj lwm ntawm LED lub teeb qhov chaw ntawm tsawg voltage (VF = 3.2V) thiab siab tam sim no (IF = 300-700mA), nws generates cua sov ntau. Cov khoom siv teeb pom kev zoo ib txwm muaj qhov chaw tsawg, thiab nws nyuaj rau thaj chaw me me kom cov cua sov kom sai sai. Txawm hais tias siv ntau yam kev daws teeb meem cua sov, cov txiaj ntsig tsis txaus siab thiab dhau los ua qhov teeb meem tsis daws teeb meem rau LED teeb pom kev zoo. Peb ib txwm siv zog los nrhiav cov khoom siv hluav taws xob yooj yim thiab yooj yim siv nrog cov thermal conductivity zoo thiab tus nqi qis.
Tam sim no, thaum lub teeb ci LED tau siv rau, kwv yees li 30% ntawm cov hluav taws xob hluav taws xob tau hloov mus rau lub teeb lub zog, thiab qhov seem yog hloov mus rau lub zog hluav taws xob. Yog li ntawd, kev xa tawm ntau lub zog thermal kom sai li sai tau yog lub tshuab tseem ceeb hauv kev tsim qauv ntawm LED teeb. Thermal zog yuav tsum tau dissipated los ntawm thermal conduction, convection, thiab hluav taws xob. Tsuas yog los ntawm kev xa tawm cua sov kom sai li sai tau tuaj yeem ua kom cov kab noj hniav kub hauv lub teeb ci LED txo qis, lub zog hluav taws xob tiv thaiv kev ua haujlwm nyob rau hauv ib puag ncig kub kub ntev, thiab kev laus ntxov ntxov ntawm lub teeb ci LED tshwm sim los ntawm lub sij hawm ntev. -Kev ua haujlwm kub yuav tsum zam.

Lub tshav kub dissipation txoj kev ntawm LED teeb pom kev zoo fixtures
Vim hais tias LED teeb qhov chaw lawv tus kheej tsis muaj infrared los yog ultraviolet hluav taws xob, lawv tsis muaj hluav taws xob kub dissipation muaj nuj nqi. Txoj kev tshav kub dissipation ntawm LED teeb pom kev zoo tuaj yeem tsuas yog xa tawm los ntawm lub dab dej kub ua ke nrog LED hlaws board. Lub tshuab hluav taws xob yuav tsum muaj lub luag haujlwm ntawm kev siv hluav taws xob, hluav taws xob convection, thiab hluav taws xob hluav taws xob.
Txhua lub tshuab hluav taws xob, dhau li nws tuaj yeem hloov cov cua sov los ntawm cov cua sov mus rau saum npoo ntawm lub tshuab hluav taws xob, feem ntau yog nyob ntawm convection thiab hluav taws xob kom dissipate cua sov rau hauv huab cua. Thermal conduction tsuas yog daws txoj hauv kev ntawm kev hloov hluav taws xob, thaum thermal convection yog lub luag haujlwm tseem ceeb ntawm cov dab dej kub. Lub tshav kub dissipation kev ua tau zoo yog txiav txim siab los ntawm qhov chaw tshav kub dissipation, cov duab, thiab ntuj convection siv, thiab thermal tawg tsuas yog ib qho kev pabcuam.
Feem ntau hais lus, yog tias qhov kev ncua deb ntawm qhov chaw tshav kub mus rau saum npoo ntawm lub dab dej kub yog tsawg dua 5 hli, tsuav yog qhov thermal conductivity ntawm cov khoom muaj ntau dua 5, nws cov cua sov tuaj yeem raug xa tawm, thiab qhov seem ntawm cov cua sov yuav tsum. yuav dominated los ntawm thermal convection.
Feem ntau cov teeb pom kev zoo ntawm LED tseem siv cov hlaws LED uas tsis tshua muaj hluav taws xob (VF = 3.2V) thiab siab tam sim no (IF = 200-700mA).
