Hauv kev teeb pom kev sab nraum zoov ntawm cov teeb pom kev nyab xeeb, Lub Teeb Kev Ruaj Ntseg Hauv Tsev ua lub luag haujlwm tseem ceeb.Qee lub sijhawm tshwj xeeb, xws li teeb pom kev zoo ntawm cov squares, kev sib tshuam, qee qhov chaw, thiab lwm yam, vim lawv qhov tshwj xeeb, los yog cov teeb pom kev zoo, qee zaum muaj teeb pom kev zoo siab yog feem ntau xav tau.Yav dhau los, ntau lub teeb pom kev zoo siv lub zog hluav taws xob high-pressure sodium teeb nrog cov qauv ntawm ntau lub teeb taub hau kom tau raws li qhov xav tau ntawm lub teeb pom kev zoo.
Qhov zoo ntawm radiator ntawm lub teeb yog qhov teeb meem tseem ceeb uas cuam tshuam ncaj qha rau qhov loj ntawm lub teeb lwj.Peb txoj kev yooj yim ntawm kev siv hluav taws xob dissipation thiab kev hloov hluav taws xob ntawm lub teeb vaj tsev yog: conduction, convection thiab hluav taws xob.Kev tswj xyuas thermal kuj pib los ntawm peb yam no, uas tau muab faib ua ntu ntu.Thiab kev tsom xam tsis tu ncua.Txoj kev sib kis tseem ceeb ntawm lub tshuab hluav taws xob yog kev coj ua thiab convection heat dissipation, thiab radiant heat dissipation nyob rau hauv natural convection tsis tuaj yeem tsis quav ntsej.Cov khoom siv teeb pom kev zoo feem ntau yog siv high-power LEDs.
Tam sim no, lub luminous efficiency ntawm coj mus muag high-power LEDs tsuas yog 15% mus rau 30%, thiab feem ntau ntawm cov seem ntawm lub zog yog hloov mus rau hauv tshav kub zog.Yog tias lub zog cua sov tsis tuaj yeem tso tawm tau zoo, nws yuav ua rau muaj qhov tshwm sim loj.Qhov kub thiab txias yuav txo cov luminous flux thiab luminous efficiency ntawm LED, ua rau lub teeb yoj redshift, xim cam, thiab kuj ua rau phem phenomena xws li ntaus ntawv aging.Qhov tseem ceeb tshaj plaws yog tias lub neej ntawm LED yuav raug txo qis, vim lub teeb lwj ntawm LED lossis nws lub neej.Nws yog ncaj qha ntsig txog nws qhov kub thiab txias.Yog tias cov cua sov dissipation tsis zoo, qhov sib txuas kub yuav siab thiab lub neej yuav luv.Raws li Arrhenius txoj cai, lub neej yuav txuas ntxiv 2 zaug rau txhua txhua 10 ° C txo qhov kub.
