Niaj hnub no, kuv xav qhia rau koj txog kev cuam tshuam ntawm LED teeb ntawm lub tshav kub dissipation ntawm cov teeb. Cov ntsiab lus tseem ceeb yog raws li nram no:
1, Qhov cuam tshuam ncaj qha tshaj plaws-tsis zoo cua sov dissipation ncaj qha ua rau txo qis kev pab cuam lub neej ntawm LED teeb
Txij li thaum LED teeb hloov hluav taws xob rau hauv lub teeb pom kev, muaj teeb meem hloov dua siab tshiab, uas tsis tuaj yeem hloov 100% ntawm hluav taws xob hluav taws xob rau hauv lub teeb lub zog. Raws li txoj cai lij choj ntawm kev txuag hluav taws xob, hluav taws xob ntau dhau tau hloov mus rau lub zog hluav taws xob. Yog hais tias lub tshav kub dissipation qauv tsim ntawm LED teeb tsis tsim nyog, qhov no ntawm lub zog hluav taws xob tsis tuaj yeem tshem tawm sai sai. Tom qab ntawd vim qhov me me ntawm LED ntim, LED teeb yuav khaws ntau lub zog cua sov, ua rau lub neej txo qis.
2, ua rau cov khoom tsis zoo
Feem ntau cov khoom siv hluav taws xob siv tau ntev, ib feem ntawm cov khoom yuav yooj yim rau oxidize. Raws li qhov kub ntawm LED teeb nce, cov ntaub ntawv no rov qab oxidized ntawm qhov kub thiab txias, uas yuav ua rau qhov tsis zoo, thiab lub neej yuav luv. Nyob rau tib lub sijhawm, vim tias qhov hloov pauv, lub teeb ua rau muaj ntau yam thermal expansion thiab txias contraction, kom lub zog ntawm cov khoom raug puas tsuaj.
3, overheating ua rau tsis ua hauj lwm ntawm cov khoom siv hluav taws xob
Qhov no yog ib qho teeb meem ntawm semiconductor cua sov qhov chaw, thaum lub LED kub nce, cov hluav taws xob impedance nce, uas ua rau ib tug nce nyob rau hauv tam sim no, nce tam sim no ua rau lub nce tshav kub, yog li reciprocating lub voj voog, ntau cua sov yuav tshwm sim, nws thiaj li ua rau hluav taws xob. Cheebtsam overheating thiab kev puas tsuaj, ua rau hluav taws xob tsis ua hauj lwm.
4. Cov khoom siv ntawm lub teeb thiab lub teeb yog deformed vim overheating
LED teeb yog tsim los ntawm ntau qhov chaw, qhov sib txawv ntawm cov khoom sib txawv. Qhov loj ntawm cov ntaub ntawv no txawv ntawm qhov thermal expansion thiab txias contraction. Thaum qhov kub thiab txias, qee cov ntaub ntawv yuav nthuav thiab khoov vim overheating. Yog tias qhov chaw nruab nrab ntawm qhov chaw nyob ib sab me dhau, ob qho tib si tuaj yeem nyem, uas tuaj yeem ua rau cov khoom puas tsuaj rau qhov mob hnyav.
Qhov tsis zoo cua sov dissipation ntawm LED teeb yuav tsim teeb meem ntau heev. Cov teeb meem ntawm cov khoom siv no yuav ua rau kev poob qis ntawm kev ua haujlwm ntawm tag nrho LED teeb thiab ua rau lawv lub neej luv. Yog li ntawd, LED tshav kub dissipation tshuab yog ib qho teeb meem kev lag luam tseem ceeb. Nyob rau hauv lub neej yav tom ntej, thaum txhim kho LED lub zog hloov pauv tus nqi, LED hluav taws xob dissipation qauv yuav tsum tsim kom muaj txiaj ntsig zoo, kom cov teeb pom kev zoo ntawm LED tuaj yeem tshem tawm cov teeb meem ntawm cov cua sov.
