Cov nyhuv ntawm qhov kub thiab txias ntawm LED zaub
Oct 14, 2022| Qhov cuam tshuam ntawm qhov kub thiab txias ntawm LED zaub muaj tsib lub ntsiab lus hauv qab no:
Ua ntej, qhov kub thiab txias ntau dhau tuaj yeem ua rau muaj kev puas tsuaj tag rau LED zaub.
(1) Yog tias qhov ntsuas kub ntawm LED zaub ntau tshaj qhov ntsuas kub ntawm lub nti, qhov ua tau zoo ntawm LED zaub yuav poob sai, ua rau pom tseeb lub teeb attenuation thiab puas.
(2) LED zaub yog feem ntau encapsulated nrog pob tshab epoxy resin. Yog hais tias qhov sib txuas kub siab tshaj qhov kub hloov pauv hloov pauv (feem ntau yog 125), cov khoom ntim yuav dhau los ua roj hmab, thiab cov thermal expansion coefficient yuav nce siab, ua rau tsis ua haujlwm ntawm LED zaub.
Qhov thib ob, qhov ntsuas kub siab tuaj yeem ua rau lub neej luv ntawm LED cov lus qhia.
Lub neej ntev ntawm LED zaub yog tus cwj pwm los ntawm lub teeb lwj, uas yog, qhov ci ntsa iab tau qis dua thiab qis dua lub sijhawm kom txog thaum nws tawm mus. Feem ntau, lub sij hawm thaum lub luminous flux ntawm LED zaub screen decays los ntawm 30 yog txhais raws li nws lub neej.
