Hauv kev lag luam txawv teb chaws txoj kev teeb pom kev lag luam, cov neeg siv khoom qee zaus qhia txog LED chips tig dub, ceev lumen depreciation, los yog outright tsis ua hauj lwm. Chip blackening tsis yog qhov teeb meem me me - nws tuaj yeem ua rau lub teeb pom kev ua haujlwm tsis zoo lossis ua rau lub teeb pom kev tsis ua haujlwm ntxov thiab thov kev tsis sib haum xeeb. Kos rau xyoo ntawm kev xa tawm thiab tom qab- kev muag khoom, ntawm no yog cov laj thawj tseem ceeb thiab cov tswv yim tiv thaiv los pab kev yuav khoom thiab pab pawg engineering tiv thaiv teeb meem ua ntej.
Overcurrent thiab Overvoltage yog qhov feem ntau tshwm sim ncaj qha
LED chips yog rhiab heev rau tam sim no thiab voltage. Thaum tus neeg tsav tsheb tso zis ntau tshaj lub nti cov ntsuas tam sim no, cov xov hlau sab hauv thiab cov qauv overheat sai heev thiab ua puas, tawm hauv pom blackening ntawm qhov chaw. Overvoltage yog qhov txaus ntshai sib npaug - siab tam sim ntawd -voltage spike tuaj yeem rhuav tshem cov khoom hluav taws xob sab hauv. Hauv cov haujlwm tiag tiag, kev xaiv tsav tsheb tsis raug, kev hloov pauv loj ntawm kab sib chaws, lossis kev tiv thaiv tus neeg tsav tsheb tsis txaus yog qhov tshwm sim ntau zaus. High-zoo tas li- cov tsav tsheb tam sim no nrog kev sib raug zoo ua rau txo qhov kev pheej hmoo no.
Kub kub thiab tsis zoo cua sov Dissipation Accelerate Chip Aging
LEDs ua kom sov thaum ua haujlwm. Yog tias lub luminaire thermal tsim tsis txaus, lossis yog tias qhov chaw teeb tsa muaj qhov cua tsis zoo thiab lub caij ntuj sov lub caij ntuj sov ntev, qhov ntsuas kub ntawm cov nti tuaj yeem tshaj nws qhov ntsuas ntau. Cov ntaub ntawv thiab cov qauv hloov pauv nyob rau hauv qhov kub thiab txias, nws thiaj li tshwm sim raws li nti blackening thiab sai lumen poob. Peb tau pom ntau qhov xwm txheej uas thaiv cov dab dej kub los yog tsis sib xws thermal paste daim ntawv thov sai sai ua rau kev ua tsis tiav.
Electrostatic Discharge thiab Inherent Chip Quality Issues
Yog tias kev tiv thaiv- kev ntsuas zoo li qub tsis txaus thaum lub sijhawm tsim khoom, thauj, lossis kev teeb tsa, cov nqi hluav taws xob zoo li qub tuaj yeem tso tawm sai sai thiab ua rau cov qauv sab hauv ntawm cov nti, ua rau blackening. Tsis tas li ntawd, kev tsim khoom tsis raug lossis cov khoom siv tsis zoo hauv cov nti nws tus kheej tuaj yeem ua rau tsis ua haujlwm ntxov ntxov raws li kev siv ib txwm muaj. Xaiv cov khoom lag luam muaj npe nrov nrog cov khoom ruaj khov thiab nruj me ntsis tswj kev tiv thaiv - cov txheej txheem zoo li qub thoob plaws hauv cov saw hlau yuav txo cov kev ua tsis tiav ntawm qhov chaw.
Cov ntsiab lus ntawm cov kev tiv thaiv zoo
Txhawm rau kom tsis txhob LED txoj kev teeb ci nti blackening, plaub lub ntsiab lus tseem ceeb: ua haujlwm tam sim no thiab qhov hluav taws xob nruj me ntsis hauv cov kev txwv; tsim kom muaj cua sov zoo-dissipation system los tswj qhov kub thiab txias; siv los tiv thaiv- ntsuas zoo li qub los ntawm kev tsim khoom los ntawm kev teeb tsa; thiab tsis tu ncua xaiv cov chips txhim khu kev qha thiab cov tsav tsheb. Thaum cov kauj ruam no tau ua tiav zoo, qhov tshwm sim ntawm nti blackening poob qis, thiab tag nrho cov khoom siv tau zoo dua qub thiab ruaj khov.
