LED teeb pom kev zoo cov ntaub ntawv yog xam raws li cov sij hawm siv. Lub neej ntev ntawm ib qho LED feem ntau yog ntsuas los ntawm qib ntawm luminous flux lwj nws tuaj yeem tswj tau thiab lub sijhawm siv. Hauv qab no yog cov lus piav qhia ntxaws ntxaws ntawm LED teeb pom kev zoo cov ntaub ntawv thiab lub neej ntev:
LED Lub teeb Decay xam:
Raws li Kev Siv Sijhawm: LED teeb pom kev puas tsuaj feem ntau yog xam raws li cov teev nws siv. Piv txwv li, yog siv rau 10 teev nyob rau ib hnub rau tag nrho ntawm 3000 teev, lub luminous flux yuav txo los ntawm 3%.
Cumulative Decay: Decay yog cumulative. Tom qab thawj 3000 teev ntawm kev siv, yog tias thawj zaug luminous flux yog 100 LM, cov luminous flux decayed ua 97 LM. Rau 3000 teev tom ntej no, kev lwj yog xam li 3% ntawm 97 LM, thiab lwm yam.
Kev ntsuam xyuas LED Lifespan:
Luminous Flux Maintenance Lub Sijhawm: Lub neej ntev ntawm LED feem ntau yog ntsuas los ntawm lub sijhawm nws tuaj yeem tswj tau qee qhov luminous flux. Piv txwv li, ib lub chaw tsim khoom yuav thov tias LED tuaj yeem tswj tau 70% ntawm nws qhov pib luminous flux rau kaum tawm txhiab teev nyob rau hauv kev siv tas li.
Cov yam ntxwv cuam tshuam rau LED lifespan: Lub neej tiag tiag ntawm LED chips yog cuam tshuam los ntawm ntau yam, nrog rau kev ua haujlwm ib puag ncig, kev ruaj ntseg ntawm cov tsav tam sim no, thiab cov cua kub dissipation. Yog li ntawd, lub neej ntev ntawm LED chips yuav txawv nyob rau hauv kev siv tswv yim.
Hauv kev xaus, txhawm rau txuas ntxiv lub neej ntawm LED chips thiab txo lub teeb lwj, nws raug nquahu kom tswj xyuas lub sijhawm siv tau zoo, tswj xyuas cov cua sov kom zoo, thiab xaiv cov chips txhim khu kev qha LED thiab cov tsav tsheb.
