Yuav ua li cas tswj qhov kub ntawm LED teeb hauv qab 40 degrees?

Thaum thaj tsam ntawm lub plhaub aluminium txias yog qhov loj txaus, yuav ua li cas tswj qhov kub ntawm 15W LED teeb nyob rau hauv 40 degrees?
Muaj peb lub ntsiab lus rau lo lus nug no uas yuav tsum tau qhia meej ua ntej:

1, qhov kub ntawm qhov sib txawv nrog koj ib puag ncig yog dab tsi, uas yog, qhov kub thiab txias.

Yog tias qhov ntsuas kub ntawm qhov ntsuas kub yog 40 degrees, nws tsis tuaj yeem txo qhov kub ntawm qhov kub mus rau hauv 40 degrees, thiab nws yog tsis yooj yim sua rau lub tshav kub dissipation ntawm ib cheeb tsam infinite kom txo tau qhov kub ntawm lub cua sov lub cev kom qis dua qhov kub ntawm ambient kub.

Cov qauv kev suav dav dav yog 75 square metres ntawm thaj chaw 1W tshav kub (yog cua sov, tsis yog lub zog LED), uas tuaj yeem ua kom ntseeg tau tias feem ntau ntawm cov cua sov tawm los ntawm LED yog dissipated. Qhov kev xaiv ntawm lub tshuab hluav taws xob nyob ntawm qhov zoo ntawm cov LED koj siv, qhov hluav taws xob poob, thiab qhov tam sim no koj ntxiv rau LED (yog tias ntau dua 350mA, qhov feem pua ​​​​ntawm cov hluav taws xob nce ntxiv raws li feem pua ​​​​ntawm tag nrho cov zog ntxiv. nce).

2, seb lub hwj huam mov yog built-in los yog sab nraud, seb qhov cua sov ntawm lub hwj chim yuav tsum raug xam;

3, thaum lub teeb hluav taws xob LED cais tawm hauv lub teeb kuj tuaj yeem ua tiav qhov ntsuas kub sab nraud, xws li cov teeb pom kev hauv tsev tam sim no, kev siv lub npe hu ua ceramic radiator, yog li thaum ntsuas qhov kub ntawm lub teeb, tsis yog rau kuaj qhov kub nce ntawm lub teeb sab nraud, siv ntau dua yog qhov kub ntawm LED hlws ris
