1, Vim li cas LED teeb ua kom sov
Ua ntej, peb yuav tsum tau qhia meej tias cov teeb ci LED ua rau muaj qee qhov cua sov thaum ua haujlwm. Qhov no yog vim hais tias thaum lub sij hawm ua hauj lwm ntawm LED teeb, ib feem ntawm lub zog poob nyob rau hauv daim ntawv ntawm thermal zog thaum lub sij hawm tus txheej txheem ntawm hloov hluav taws xob hluav taws xob mus rau lub teeb lub zog. Tshwj xeeb, cov cua kub ntawm LED teeb feem ntau yog los ntawm cov hauv qab no:
Cov cua sov sab hauv ntawm LED chips: LED chips yog cov khoom tseem ceeb ntawm LED teeb, thiab thaum tam sim no dhau los ntawm LED chips, qee qhov hluav taws xob tsim tawm. Qhov no yog vim hais tias thaum tam sim no dhau los ntawm cov khoom siv semiconductor, nws ntsib kev tiv thaiv thiab ua rau lub zog poob, uas yog dissipated nyob rau hauv daim ntawv ntawm thermal zog.
Tsav Circuit Court cua sov: Tus tsav tsheb Circuit Court ntawm lub teeb LED yog lub luag hauj lwm rau kev hloov cov input voltage thiab tam sim no mus rau hauv voltage thiab tam sim no haum rau lub lag luam ntawm LED nti. Thaum lub sij hawm hloov dua siab tshiab, cov khoom nyob rau hauv lub voj voog tsav tsheb yuav tsim ib qho nqi ntawm cov cua sov.
Tsis zoo cua sov dissipation ntawm lub teeb qauv: Yog hais tias lub tshav kub dissipation qauv tsim ntawm LED teeb yog tsis tsim nyog los yog thermal conductivity ntawm tshav kub dissipation khoom yog tsis zoo, nws yuav ua rau lub tshav kub generated los ntawm lub LED teeb thaum lub sij hawm ua hauj lwm kom tsis txhob dissipated nyob rau hauv lub sij hawm, uas yuav ua rau lub tshav kub generated los ntawm LED teeb thaum lub sij hawm ua hauj lwm kom tsis txhob dissipated nyob rau hauv lub sij hawm. nyob rau hauv ib qho kev nce hauv qhov kub thiab txias ntawm LED teeb.
2, Cov yam ntxwv cuam tshuam ntawm LED teeb cua sov
Cov cua sov ntawm LED teeb yog cuam tshuam los ntawm ntau yam, suav nrog kev ua haujlwm ntawm LED chips, tsim kev tsav tsheb, thiab kev ua haujlwm kub ntawm cov teeb pom kev zoo. Tshwj xeeb:
Kev ua haujlwm ntawm LED chips: Kev ua haujlwm ntawm LED chips yog qhov tseem ceeb cuam tshuam rau cov cua sov ntawm LED teeb. High quality LED chips muaj lub teeb pom kev zoo dua thiab qis thermal kuj, yog li tsim hluav taws xob tsawg dua.
Kev tsim hluav taws xob tsav tsheb: Kev tsim hluav taws xob tsav tsheb kuj yog qhov tseem ceeb cuam tshuam rau cov cua sov ntawm LED teeb. Kev tsim hluav taws xob tsim hluav taws xob tsim nyog tuaj yeem ua kom ntseeg tau tias LED chips ua haujlwm hauv lub xeev ua haujlwm ruaj khov, txo qis hluav taws xob thiab hluav taws xob hluav taws xob.
Kev ua tau zoo ntawm cov teeb pom kev zoo ntawm cov teeb pom kev zoo: Kev ua haujlwm kub dissipation ntawm lub teeb qauv muaj kev cuam tshuam ncaj qha rau cov cua sov ntawm LED teeb. Kev tsim hluav taws xob tsim hluav taws xob tsim nyog tuaj yeem cuam tshuam cov cua sov uas tsim los ntawm LED teeb thiab txo lawv qhov kub thiab txias.
3, Thaum tshav kub kub dissipation tsim ntawm LED teeb
Yuav kom txo tau cov hluav taws kub ntawm LED teeb, txhim kho lawv cov kev pab cuam lub neej thiab kev ruaj ntseg, nws yog ib qho tsim nyog yuav tau txais ib qho kev tsim hluav taws xob tsim nyog. Nov yog qee qhov kev tsim qauv cua txias:
Ua kom lub tshav kub dissipation cheeb tsam: Los ntawm kev ua kom sov dissipation cheeb tsam ntawm LED teeb pom kev zoo fixtures, lub efficiency ntawm tshav kub dissipation yuav nce. Piv txwv li, tsim cov cua kub dissipation qhov los yog fins ntawm lub teeb vaj tsev kom ua rau kom cov cua sov dissipation cheeb tsam.
Siv cov khoom siv thermal conductivity zoo: Xaiv cov khoom siv thermal conductivity zoo li cov ntaub ntawv kub dissipation rau LED teeb pom kev zoo, xws li aluminium alloy, tooj liab, thiab lwm yam ntaub ntawv hlau, tuaj yeem ua kom sov tau zoo dua.
Optimizing lub tshav kub dissipation qauv: Los ntawm optimizing tus tsim ntawm tshav kub dissipation qauv, xws li siv convection tshav kub dissipation, hluav taws xob tshav kub dissipation, thiab lwm yam.
