Ib yam dab tsi txog hauv qab dej teeb lwj

LED teeb lwj yog hais txog qhov tshwm sim uas LED luminaires maj mam txo lawv cov luminous efficiency thiab maj mam tsis muaj zog lawv lub teeb tso zis thaum siv. Lub teeb lwj feem ntau yog qhia nyob rau hauv ob txoj kev:
1) feem pua ​​(%): Piv txwv li, lub luminous flux ntawm LED tom qab 1000 teev ntawm kev ua haujlwm poob mus rau 90% ntawm tus nqi pib, qhia tias lub teeb lwj yog 10%;
2) Lumen Maintenance: Piv txwv li, "L70" qhia lub neej (teev) thaum lub luminous flux poob mus rau 70% ntawm tus nqi pib;

Lub teeb pom kev tsis zoo txhais tau hais tias cov khoom siv hluav taws xob zoo yog qhov zoo, cov khoom siv hluav taws xob zoo tshaj plaws, thiab lub neej ntev dua: Piv txwv li, cov khoom siv hluav taws xob zoo yuav poob qis los ntawm 10% ntawm 25,000 xuab moos, thaum cov coj tsis zoo yuav poob ntau dua 30% ntawm 10,000 xuab moos.

LED kev lag luam tus qauv siv:
Ordinary LED:L70 lub neej ntawm li 25,000 ~ 50,000 teev.
High-end LED (xws li pob COB):L80 lub neej tuaj yeem tshaj 50,000 teev.

Yam tseem ceeb cuam tshuam rau lub teeb lwj:
Kub:Tsis zoo cua sov dissipation yuav ceev phosphor thiab nti aging (hluav taws xob kub 10 ° C ib liter, lub neej tej zaum yuav halved).
Tsav tam sim no:Kev ua haujlwm ntau dhau (xws li qhov muag tsis pom kev ua kom pom tseeb tam sim no) yuav ua kom lub teeb tawg.
Cov ntaub ntawv thiab txheej txheem:Tsis zoo phosphors, nplaum los yog chips tuaj yeem ua rau lub teeb tawg thaum ntxov.
LED teeb decay standard
1) Ordinary LED: L70 / 25,000 ~ 50,000 teev
2) High-end LED: L80 / 50,000 teev

Qhov cuam tshuam ntawm lub teeb lwj ntawm lub pas dej hauv qab lub teeb:
txo qhov ci ntsa iab: Thaum lub teeb tsis ua haujlwm hnyav, qhov teeb pom kev zoo ntawm lub teeb txo qis, thiab cov roj teeb yuav tsum tau hloov lossis nce ntxiv.
Xim kub fading: Qee lub teeb LED tawg nrog cov xim kub hloov (xws li xiav lossis daj), cuam tshuam rau xim rendering.
Lub neej luv luv: Lub teeb pom kev nrawm dhau txhais tau hais tias lub neej ua haujlwm tiag tiag ntawm LED yog qis dua li lub neej theoretical (feem ntau nrog lub luminous flux txij nkawm tus nqi L70 raws li lub neej kawg).

Lub teeb lwj yog qhov taw qhia tseem ceeb los ntsuas qhov kev ntseeg siab thiab lub neej ntawm lub teeb hauv qab dej, thiab lub teeb pom kev tsis zoo yog lub cim ntawm cov khoom siv zoo LED.Thaum xaiv, xyuam xim rau cov flux tu nkhaus muab los ntawm cov chaw tsim khoom (xws li LM-80 daim ntawv qhia), es tsis yog saib ntawm lub neej nominal.Shenzhen Heguang Teeb pom kev zoo Co., Ltd tsim cov khoom zoo nrog 0% 2% teeb pom kev zoo hauv qab dej. xyoo, nyem rau ntawm daim duab hauv qab no kom tau txais ntau dua ntawm cov teeb pom kev qis qis hauv qab dej pas dej ua ke cov ntaub ntawv:
