Lumen Depreciation ua yooj yim

Hloov mus rau LED teeb thaum kawg yuav pab koj txuag nyiaj. Tab sis li cas txog lumen poob? Kawm paub ntxiv txog lumen degradation thiab nws cuam tshuam li cas rau koj lub teeb LED.

Lumen poob Ua kom yooj yim dua

Muaj tseeb tiag, lub teeb emitting diodes-los yogLEDs-yog ib qho kev txhim kho ntawm cov pa hlau halide lossis cov teeb fluorescent. Hloov mus rau LED teeb yuav pab koj txuag tau nyiaj ntau ntau lub sijhawm. Tab sis li cas txog lumen poob? Yog tias qhov no yog kab lus coj txawv txawv rau koj, nyeem ntxiv kom paub ntxiv txog lumen depreciation thiab txhim kho koj txoj kev paub txog kojLED teeb pom kev zoo.
 

Lumen depreciation yog dab tsi?

Txawm hais tias nws yog dav lees paub tiasLED teebmuaj sia nyob ntev dua li cov teeb fluorescent lossis hlau halide, nws kuj yog qhov tseeb tias tsis muaj qhov muag teeb nyob mus ib txhis. Tsis zoo li cov teeb pom kev zoo, LEDs tsis yog tam sim ntawd poob thiab cia koj nyob hauv qhov tsaus ntuj. Hloov chaw, thaum lawv lub neej, LEDs maj mam tso tawm tsawg dua thiab tsawg dua lumens. Cia peb saib qhov no ...
Cov "lumen" yog qhov ntsuas ntawm lub teeb ci. Ntau lumens tsim sib npaug ntau lub teeb ci ntsa iab.
Lub teeb ci LED ua ntej tso tawm "thawj lumens," lossis qhov ntau ntawm lub teeb tsim tawm sai sai tom qab kev ruaj khov tab sis ua ntej pib degradation. LED yog nyob rau ntawm nws brightest thiab siab tshaj plaws tso zis ces.
Tus nqi ntawm lub teeb tsim los ntawm lubLEDpoob raws sijhawm. Qhov no yog hu ua "depreciation."
Ib qho qauv yooj yim tso cai rau ib qho los suav lumen depreciation txhua lub sijhawm. Faib LED qhov pib lumen tso zis los ntawm LED lub lumen tso tawm ntawm txhua lub sijhawm, "txhais tau tias lumens." Qhov txiaj ntsig ntawm qhov sib npaug no yuav yog tus lej. Ib qho 0.8 feem, piv txwv li, qhia tias LED ua haujlwm ntawm 80% ntawm nws qhov peev xwm qub.

Yog li, thaum twg ib qhoLED teebxav tau kev hloov lossis "ua tsis tiav"?

Txawm hais tias muaj qee qhov kev tsis sib haum xeeb ntawm cov ntsiab lus no, feem ntau pom zoo raws li lub sijhawm los hloov LED qhov muag teev yog thaum lawv tsim 70% lossis tsawg dua ntawm lawv cov thawj lumen tso zis. Kuj hu ua L70, lub sijhawm no yog "lumen txij nkawm lub neej." Lub teeb lub neej ntawm LED yog suav hauv cov xuab moos. L7o yog cov sij hawm ntawm lub teeb ib qho LED muab ua ntej 70% ntawm cov zis thawj.
