Yog vim li cas rau lub teeb attenuation ntawm LED zaub
Oct 15, 2022| (1) Cov khoom tsis xws luag hauv LED zaub nti khoom yuav nrawm nrawm thiab sib npaug ntawm qhov kub siab dua, thiab txawm cuam tshuam rau thaj chaw teeb pom kev zoo, tsim ntau qhov chaw tsis muaj hluav taws xob sib txuas, uas ua rau txo qis kev ua haujlwm ntawm LED zaub. Tsis tas li ntawd, nyob rau hauv qhov kub thiab txias, qhov micro-defects nyob rau hauv cov khoom thiab cov impurities nthuav sai heev los ntawm lub interface thiab cov hluav taws xob phaj tseem yuav tau nkag mus rau hauv lub teeb-emitting cheeb tsam, tsim ib tug loj tus naj npawb ntawm cov sib sib zog nqus zog theem, uas yuav kuj yuav tsum tau nkag mus rau hauv lub teeb-emitting cheeb tsam. ceev lub teeb lwj ntawm LED zaub ntaus ntawv.
(2) Cov pob tshab epoxy resin yuav denature thiab tig daj ntawm qhov kub thiab txias, uas yuav cuam tshuam rau nws lub teeb kis tau tus mob. Qhov siab dua qhov kev khiav hauj lwm kub, qhov txheej txheem no tshwm sim sai dua, uas yog lwm qhov ua rau lub teeb attenuation nyob rau hauv LED zaub.
(3) Lub teeb attenuation ntawm phosphors kuj yog ib qho tseem ceeb cuam tshuam rau lub teeb attenuation ntawm LED zaub, vim hais tias lub attenuation ntawm phosphors yog heev hnyav nyob rau hauv high kub.
Yog li ntawd, qhov kub thiab txias yog qhov tseem ceeb ntawm lub teeb lwj ntawm LED zaub thiab lub neej luv ntawm LED zaub.
Ntau hom ntawm LED zaub muaj qhov sib txawv lub teeb attenuation. Feem ntau LED zaub manufacturers yuav muab cov txheej txheem ntawm lub teeb attenuation nkhaus. Lub luminous flux attenuation ntawm LED zaub tshwm sim los ntawm qhov kub thiab txias yog irreversible, thiab lub luminous flux ua ntej lub teeb irreversible attenuation ntawm LED zaub tsis tshwm sim, uas yog hu ua "thawj luminous flux" ntawm LED zaub.
