Streamlined Lumen Depreciation

Cov ntsiab lus

1. Lumen Depreciation Streamlined
2. Lumen depreciation yog dab tsi?
3. Nyob rau hauv dab tsi juncture yog ib tug LED teeb pom tau tias "ua tsis tau tejyam" los yog yuav tsum tau hloov?

Hloov mus rauLED teeb pom kev zootuaj yeem tau txais txiaj ntsig ntev - txuag nyiaj txiag. Dab tsi yog qhov xwm txheej ntawm lumen depreciation? Tshawb xyuas lumen lwj thiab nws qhov cuam tshuam rau koj lub teeb pom kev zoo LED.

Lumen Depreciation Streamlined

Lub teeb Emitting Diodes (LEDs) sawv cev rau kev nce qib tseem ceeb tshaj li cov pa fluorescent lossis hlau halide teeb pom kev zoo. Kev hloov mus rau LED teeb pom kev zoo tuaj yeem ua rau lub sijhawm ntev - txuag nyiaj txiag. Dab tsi yog qhov xwm txheej ntawm lumen depreciation? Yog tias lo lus no tsis paub meej rau koj, nyeem txuas ntxiv kom nkag siab txog lumen depreciation thiab txhim kho koj kev nkag siab ntawmLED teeb pom kev zoo.

Lumen depreciation yog dab tsi?

Txawm hais tias nws yog dav lees paub tiasLED teebmuaj lub neej ntev dua li cov fluorescent lossis hlau halide qhov muag teev, nws tseem muaj qhov tseeb tias tsis muaj qhov muag teeb nyob mus ib txhis. Hauv kev sib piv rau cov teeb pom kev zoo, LEDs tsis ua haujlwm sai sai, yog li tiv thaiv tag nrho qhov tsaus ntuj. Hloov pauv, LEDs nce zuj zus lawv cov lumen tso zis thaum lawv lub neej. Cia peb txheeb xyuas qhov no hauv kev nthuav dav ntxiv.
"Lumens" yog cov chav ua haujlwm los ntsuas qhov ci ntawm lub teeb. Ua kom lumens ua kom muaj kev ci ntsa iab.
Thaum xub thawj installation, ibLED teeboutputs "thawj lumens," uas yog hais txog lub teeb tso zis uas tsim tam sim ntawd tom qab stabilization, ua ntej yuav depreciation. Qhov no yog lub ntsiab lus ntawm qhov LED ua tiav nws qhov siab tshaj plaws ci ntsa iab thiab tso zis.
Lub luminous tso zis ntawm LED diminishes nrog lub sij hawm. Cov txheej txheem no yog hu ua "depreciation."
Lumen depreciation tuaj yeem suav txhua lub sijhawm los ntawm kev suav ncaj nraim. Faib LED lub lumen tso zis ntawm txhua lub sijhawm ("lub ntsiab lus lumens") los ntawm LED qhov pib lumen tso zis. Cov txiaj ntsig ntawm qhov kev suav no yuav muab tus lej lej. Qhov piv ntawm 0.8 qhia tias LED ua haujlwm ntawm 80% ntawm nws qhov peev xwm qub.

Nyob rau hauv dab tsi juncture yog ibLED teebsuav tias "ua tsis tau" lossis xav tau hloov pauv?

Txawm hais tias muaj qee qhov kev sib cav txog qhov kev kawm no, qhov kev lees paub dav dav rau kev hloov cov qij LED yog thaum lawv tso tawm 70% lossis tsawg dua ntawm lawv cov thawj lumen tso zis. Qhov kev siv lub sijhawm no yog hu ua "lumen tu lub neej," feem ntau hu ua L70. Lub neej ntev ntawm LED teeb yog ntsuas hauv cov xuab moos. L7o yog lub sijhawm teeb pom kev zoo los ntawm ib qhoLEDkom txog thaum nws ncav cuag 70% ntawm nws thawj qhov ci ci.
