Streamlined Lumen Depreciation

Hloov mus rauLED teeb pom kev zootuaj yeem ua rau 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. Hloov mus rauLEDteeb pom kev zoo tuaj yeem ua rau muaj txiaj ntsig ntev - txuag nyiaj txiag. Dab tsi yog qhov xwm txheej ntawm lumen depreciation? Yog tias lo lus no tsis paub, nyeem txuas ntxiv kom paub ntau ntxiv txog lumen depreciation thiab nkag siab tob txog koj lub teeb pom kev zoo LED.
 

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 kom ntxaws.
"Lumens" yog cov chav ua haujlwm los ntsuas qhov ci ntawm lub teeb ci. Qhov ntau dua lumen tso zis ua rau 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 nthuav tawm 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. Qhov tshwm sim ntawm qhov sib npaug no yuav yog tus 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 ib tug LED teeb pom tau tias "ua tsis tau tejyam" los yog yuav tsum tau hloov?
Txoj kev lees paub dav dav rau kev hloov cov qij LED yog thaum lawv tawm 70% lossis tsawg dua ntawm lawv cov khoom qub lumen. Qhov kev siv lub sijhawm no yog hu ua "lumen tu lub neej," feem ntau hu ua L70. Lub neej ntev ntawm ibLED teebyog ntsuas nyob rau hauv cov xuab moos. L7o yog lub sijhawm ntawm kev teeb pom kev zoo ib qho LED xa tawm ua ntej nws cov zis ploj mus rau 70% ntawm nws qib pib.

Illumination yog ib tug complex. Thov hu rau peb ntawm tus xov tooj hauv qab no yog tias koj muaj lus nug lossis xav tau kev pabcuam hauv kev xaiv qhov zoo tagnrhoLED teeb.
