LED mos module sab hauv tsev zaub puv xim

Dab tsi yog qhov cuam tshuam ntawm kev ua haujlwm kub ntawm LED hluav taws xob screen?

Nyob rau niaj hnub no daim ntawv thov dav dav ntawm LED cov ntxaij vab tshaus, txhawm rau kom siv tau cov txiaj ntsig zoo tshaj plaws ntawm cov zaub, cov tuam txhab thov yuav tsum muaj kev paub txog kev saib xyuas ntawm LED electronic screen.Txawm hais tias nws yog ib qho screen LED hluav taws xob sab hauv tsev lossis sab nraum zoov LED hluav taws xob lub vijtsam, cov cua sov yuav raug tsim tawm thaum lub sijhawm ua haujlwm, thiab cov hluav taws xob tsim hluav taws xob yuav ua rau qhov kub ntawm LED hluav taws xob screen nce.Tab sis dab tsi txog cov txiaj ntsig pom nyob rau hauv qhov kub thiab txias ua haujlwm?
Loj LED npo
Nyob rau hauv ib txwm muaj xwm txheej, sab hauv tsev LED hluav taws xob lub vijtsam tuaj yeem cuam tshuam cov cua sov vim nws qhov ci ntsa iab thiab tsis tshua muaj cua sov;Txawm li cas los xij, sab nraum zoov LED hluav taws xob lub vijtsam muaj qhov ci ntsa iab thiab kub siab, xav tau cov cua txias lossis axial kiv cua kom dissipate cua sov.Txij li thaum lub vijtsam LED hluav taws xob yog cov khoom siv hluav taws xob, qhov nce hauv qhov kub thiab txias yuav cuam tshuam rau lub teeb tawg ntawm LED hluav taws xob tshuaj ntsuam teeb hlaws, kev ua haujlwm ntawm tus tsav tsheb IC thiab kev pabcuam lub neej ntawm LED zaub.
1. LED hluav taws xob screen Circuit Court breaker thiab tsis ua hauj lwm
Kev khiav hauj lwm kub ntawm lub vijtsam LED hluav taws xob ntau tshaj qhov ntsuas kub ntawm lub nti, uas yuav txo qis kev ua haujlwm ntawm lub vijtsam LED sai, ua rau pom tseeb lub teeb tawg thiab kev puas tsuaj;Feem ntau loj LED cov ntxaij vab tshaus yog encapsulated nrog pob tshab epoxy resin.Yog tias qhov sib txuas kub siab tshaj qhov kub hloov pauv hloov pauv (feem ntau 125 ° C), cov khoom siv encapsulation yuav tig rubbery, thiab thermal expansion coefficient yuav nce siab, ua rau LED hluav taws xob screen qhib thiab ua tsis tiav.Qhov kub ntau dhau yuav cuam tshuam rau lub teeb tawg ntawm LED hluav taws xob npo.
Lub neej ntawm LED hluav taws xob screen yog tshwm sim nyob rau hauv nws lub teeb lwj, uas yog, lub brightness yuav qis dua thiab qis dua lub sij hawm mus txog rau thaum nws tawm mus.Nws feem ntau txhais tau tias yog lub neej ntawm LED hluav taws xob lub vijtsam thaum lub luminous flux yog attenuated los ntawm 30 zaug.Qhov kub thiab txias yog qhov tseem ceeb ntawm lub teeb tawg ntawm LED zaub thiab lub neej luv ntawm LED hluav taws xob npo.Lub teeb lwj ntawm ntau hom ntawm LED cov ntxaij vab tshaus hluav taws xob sib txawv.Feem ntau, LED hluav taws xob screen manufacturers yuav muab cov txheej txheem teeb pom kev zoo nkhaus.Lub attenuation ntawm lub luminous flux ntawm LED hluav taws xob screen tshwm sim los ntawm kub kub yog irreversible.Lub luminous flux ntawm LED hluav taws xob screen ua ntej irreversible lub teeb attenuation tsis tshwm sim, uas yog hu ua "thawj luminous flux" ntawm lub LED hluav taws xob screen.
2. Qhov kub thiab txias yuav txo qhov luminous efficiency ntawm LED hluav taws xob npo
Raws li qhov kub thiab txias nce, qhov concentration ntawm electrons thiab qhov nce, qhov sib txawv ntawm qhov band yuav txo, thiab cov electron txav tau qis;Raws li qhov kub nce, qhov tshwm sim ntawm radiative recombination ntawm electrons thiab qhov nyob rau hauv lub peev xwm zoo txo, uas ua rau nonradiative recombination.Thaum tshav kub kub), yog li txo qis hauv quantum efficiency ntawm LED hluav taws xob npo;qhov nce hauv qhov kub thiab txias ua rau lub ncov xiav ntawm lub nti txav mus rau qhov ntev-yoj kev taw qhia, uas ua rau lub emission wavelength ntawm lub nti tsis sib haum nrog lub zog ntawm lub zog ntawm phosphor, thiab tseem ua rau sab nraud optoelectronic screen ntawm cov dawb LED.Txo cov extraction efficiency.
Raws li qhov kub thiab txias, qhov quantum efficiency ntawm phosphor txo, qhov luminous npaum li cas txo, thiab lub teeb sab nraud extraction efficiency ntawm LED hluav taws xob npo txo;Kev ua haujlwm ntawm silica gel cuam tshuam zoo heev los ntawm qhov kub thiab txias.Raws li qhov kub thiab txias, cov thermal stress nyob rau hauv lub silica gel nce, uas ua rau ib tug txo nyob rau hauv lub refractive index ntawm silica gel, yog li cuam tshuam lub teeb efficiency ntawm LED hluav taws xob screen.
