Kev nkag siab txog cov ncauj lus no pab cov neeg siv khoom thiab cov lag luam txhim kho lawv cov kev siv teeb pom kev zoo yam tsis muaj kev ntshai ntawm kev ua tsis tiav ntxov ntxov.

1. Qhov Tseem Ceeb Qhov txawv: Vim li cas LEDs Kov Hloov Hloov Zoo dua

Physics ntawm LED Degradation

LEDs yog cov khoom ruaj khov- lub xeev cov khoom siv uas tsis muaj cov khoom tawg yooj yim lossis cov iav iav. Lawv lifespan feem ntau nyob ntawm ob yam:

Kev sib tshuam kub(kub ntawm txheej semiconductor)

Electron migrationtshaj txhiab teev

Tsis zoo li cov qhov muag teev uas tsis muaj thermal shock thaum caij tsheb kauj vab:

LEDs muaj kev ntxhov siab tsawg heev los ntawm lub voj voog qhib / tawm

Lub ntsiab hnav mechanism yogtag nrho cov sijhawm ua haujlwm, tsis hloov zaus

Comparative Failure Mechanisms

2. Cov ntaub ntawv pov thawj hauv chaw soj nstuam: Cov Kev Ntsuam Xyuas Kev Tswj Xyuas Dab tsi nthuav tawm
