Tam sim no, qhov loj tshaj technical teeb meem ntawmLED teeb pom kev zooyog tshav kub dissipation. Tsis zoo cua sov dissipation tau coj mus rau LED tsav tsheb fais fab mov thiab electrolytic capacitor ua lub luv luv board rau ntxiv kev loj hlob ntawm LED teeb pom kev zoo, thiab yog vim li cas rau kev laus ntxov ntxov ntawm LED teeb qhov chaw.

Hauv cov phiaj xwm teeb pom kev zoo siv LV LED teeb pom kev zoo, vim yog lub teeb ci LED ua haujlwm ntawm qhov tsis tshua muaj hluav taws xob (VF = 3.2V) thiab siab tam sim no (IF = 300-700mA), lub zog hluav taws xob loj heev. Cov teeb pom kev zoo ib txwm muaj qhov chaw txwv, thiab cov dab dej kub me me yog qhov nyuaj rau kev xa tawm sai sai. Txawm hais tias siv ntau yam txheej txheem cua txias, cov txiaj ntsig tsis txaus siab, dhau los ua qhov teeb meem tsis daws teeb meem rauLED teeb pom kev zoo fixtures. Peb ib txwm siv zog los nrhiav cov khoom siv hluav taws xob qis qis uas yooj yim siv, nrog cov thermal conductivity zoo.

Tam sim no, kwv yees li 30% ntawm cov hluav taws xob hluav taws xob ntawm LED lub teeb qhov chaw tau hloov mus rau lub teeb lub zog tom qab tau txais lub zog, thaum tus so yog hloov mus rau thermal zog. 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 pom kev zoo fixtures. Thermal zog yuav tsum tau dissipated los ntawm thermal conduction, convection, thiab hluav taws xob. Tsuas yog los ntawm kev xa tawm cov cua sov kom sai li sai tau tuaj yeem ntsuas qhov kub ntawm cov kab noj hniav hauv lubLED teebraug txo kom zoo, cov khoom siv hluav taws xob tiv thaiv los ntawm kev ua haujlwm nyob rau hauv ib puag ncig kub-kub ntev, thiab kev laus ntxov ntawm LED teeb qhov chaw tshwm sim los ntawm kev ua haujlwm kub mus ntev yuav tsum zam.

Thaum tshav kub kub dissipation txoj kev rau LED teeb pom kev zoo fixtures

Vim tias cov teeb ci LED tsis muaj infrared lossis ultraviolet hluav taws xob, lawv tsis muaj hluav taws xob hluav taws xob tawg ua haujlwm. Lub tshav kub dissipation txoj kev ntawm LED teeb pom kev zoo fixtures tsuas yog muab tau los ntawm cov dab dej kub ua ke nrog LED hlaws daim hlau. 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, ntxiv rau qhov muaj peev xwm hloov tau sai 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. Thaum tshav kub kub conduction tsuas yog daws txoj hauv kev ntawm kev hloov hluav taws xob, thaum thermal convection yog lub luag haujlwm tseem ceeb ntawm lub tshuab hluav taws xob. Lub tshav kub dissipation kev ua tau zoo yog txiav txim siab los ntawm qhov chaw tshav kub dissipation, duab, thiab ntuj convection siv, thaum 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 tshuab hluav taws xob tsawg dua 5 hli, tsuav yog cov khoom siv thermal conductivity ntau dua 5, nws cov cua sov tuaj yeem raug xa tawm, thiab qhov seem ntawm cov cua kub dissipation yuav tsum tau dominated los ntawm thermal convection. .

Feem ntau cov teeb pom kev zoo LED tseem siv hluav taws xob tsawg (VF = 3.2V) thiab siab tam sim no (IF = 200-700mA) LED hlaws.
