Jun 19, 2022| Lub teeb hluav taws xob LED ua haujlwm li cas?
Lub thermal tsis kam ntawm LED lub dab dej kub yuav tsum muaj ob ntu: thermal conduction thermal resistance thiab tshav kub dissipation thermal kuj. Rau ib qho ntawm cov duab ntawm LED radiator, thermal conductivity feem ntau yog cuam tshuam nrog thermal conductivity ntawm cov khoom cua sov. Lub tshav kub dissipation cheeb tsam ntawm lub radiator thiab cov hluav taws xob coefficient ntawm cov khoom nto ntawm lub radiator, qhov loj dua qhov kub dissipation cheeb tsam, qhov siab dua cov hluav taws xob coefficient, qhov me dua qhov kub dissipation thermal kuj, thiab qhov zoo dua cov cua kub dissipation nyhuv.
Lub npe hu ua LED kub dab dej yog ib qho khoom siv uas tuaj yeem xa tawm sai sai thiab dissipate cov cua sov uas tsim los ntawm LED nti rau ib puag ncig. Yog li ntawd, nws tsis txaus kom tsuas muaj ib qho chaw tshav kub dissipation li lub dab dej kub. Cov khoom siv los ua lub dab dej kub yuav tsum muaj qee yam thermal conductivity. High thermal conductivity, uas yog, kom muaj cov thermal conductivity siab, cov cua sov tsim los ntawm cov nti tuaj yeem raug xa tawm tsis tu ncua thiab thaum kawg dissipated rau hauv ib puag ncig; Yog lawm, rau cov ntaub ntawv thermally conductive, ntxiv rau thermal conductivity, lawv yuav tsum muaj qhov tshwj xeeb me me, tus nqi qis thiab siab zog. , yooj yim rau txheej txheem thiab lwm yam.
