Tom qab xyoo dhau los ntawm kev lag luam txawv teb chaws, ib qho ntawm cov kev txwv uas cov neeg siv khoom nug txog feem ntau -thiab feem ntau ua rau tsis to taub- yog "50,000-teev lifespan" ntawm txoj kev teeb. Ntau tus neeg yuav khoom siv nws txhais tau tias "lub teeb yuav kub hnyiab tau 50,000 teev yam tsis ua tsis tiav." Tsuas yog tom qab daim ntawv cog lus tau kos npe lawv pom tias lumen depreciation sai dua li qhov xav tau lossis tias tus neeg tsav tsheb tsis ua ntej. Kab lus no piav qhia txog tus qauv L70/B50 kom meej meej thiab qhia meej tias qhov twg 50,000-teev daim duab los ntawm.
L70/B50 txhais tau li cas
L70 / B50 yog tam sim no txoj kev siv dav tshaj plaws los qhia txog LED lub neej hauv kev lag luam. L70 qhia tias luminous flux yog khaws cia ntawm 70% ntawm nws cov nqi pib; B50 qhia tias 50% ntawm cov qauv tau mus txog lossis poob qis dua qib no. Kev nyeem ntawv tag nrho yog: nyob rau hauv qhov kev xeem thiab kev ua haujlwm, tom qab tshaj tawm cov sijhawm teev, 50% ntawm cov luminaires (lossis LEDs) tseem xa tawm tsawg kawg 70% ntawm lawv qhov pib lub teeb pom kev zoo.
Hauv lwm lo lus, qhov ntsuas 50,000-teev L70 / B50 tsis tau txhais hais tias lub teeb ci ntsa iab hloov pauv ntawm 50,000 teev. Nws txhais tau hais tias qhov nruab nrab lub teeb tso zis tau poob mus rau ib ncig ntawm 70% ntawm lub sijhawm ntawd. Rau txoj kev teeb pom kev zoo, 70% feem ntau suav hais tias yog qhov tsawg kawg nkaus qhov ci ci; Hauv qab no theem, hloov lossis ntxiv teeb pom kev zoo yuav tsum tau txiav txim siab.
Nws yog ib qho tseem ceeb uas yuav tsum nco ntsoov tias qhov kev ntsuas no feem ntau piav qhia txog kev txo qis lumen. Nws tsis ncaj qha them rau qhov tsis ua hauj lwm tam sim ntawd xws li kev tsav tsheb tsis ua haujlwm lossis tsis muaj dej tsis huv. Zuag qhia tag nrho luminaire kev ntseeg tau kuj nyob ntawm tus neeg tsav tsheb lub neej, sealing kev ua tau zoo, thiab thermal tsim.
Puas yog 50,000 Teev Tus Nqi Ntsuas lossis Tus Nqi Tshaj Lij?
Feem coob ntawm kev thov 50,000-teev lossis 100,000{10}}teev cov nuj nqis tsis tau txais los ntawm kev khiav luminaires tsis tu ncua rau 50,000 teev. Kev sim tag nrho tiag tiag - lub sijhawm ntsuas ntawm 50,000 teev yuav siv li ntawm tsib mus rau rau xyoo-ua tsis tau raws li lub sijhawm thiab tus nqi. Kev lag luam siv txoj kev lees paub thoob ntiaj teb ob kauj ruam:
Thawj kauj ruam yog LM-80 xeem. Cov pob LED lossis cov khoom siv tau ua haujlwm nyob rau hauv qhov ntsuas kub (feem ntau 55 degree, 85 degree, thiab lwm yam) rau 6,000 txog 10,000 teev, nrog cov luminous flux ntsuas ntawm lub sijhawm tsis tu ncua los tsim cov lumen-depreciation nkhaus tiag tiag.
Cov kauj ruam thib ob yog TM-21 qhov projection. Cov ntaub ntawv ntsuas LM-80 tau muab pub rau hauv tus qauv lej kom ntxiv sijhawm ntev dua. Tus txheej txheem ib txwm txwv qhov kev kwv yees kom tsis pub ntau tshaj rau lub sijhawm ntawm lub sijhawm xeem. Piv txwv li, nrog 10,000 teev ntawm kev xeem cov ntaub ntawv qhia L70 yuav muaj txog 60,000 teev; Yog tias qhov ntsuas tau siab dua, nws feem ntau hais tias "L70> 60,000 teev."
Yog li ntawd, 50,000-teev lub neej yog qhov tseem ceeb ntawm kev tshawb fawb tus nqi raws li cov ntaub ntawv ntsuas tsawg, tsis yog qhov ntsuas tag nrho. Qhov kev cia siab ntawm qhov projection nyob ntawm qhov ntev ntawm qhov kev sim LM-80, tus naj npawb ntawm cov qauv, qhov ntsuas kub npaum li cas sib npaug ntawm qhov sib txuas qhov tseeb hauv kev siv, thiab seb lub luminaire lub thermal tsim ua kom lub LED hlws ris kub nyob rau hauv ib tug tsim nyog ntau yam.
Tej yam uas cuam tshuam rau tiag -Lub Ntiaj Teb Lub Neej
Laboratory projections yog ua nyob rau hauv tus qauv ambient kub. Hauv kev teeb tsa tiag tiag-tshwj xeeb tshaj yog nyob rau hauv siab - kub, siab - av noo, plua plav, los yog ntug hiav txwv ntsev- qhov chaw tshuaj tsuag- qhov kub thiab txias yog feem ntau siab dua thiab lumen depreciation accelerates. Tus tsav tsheb lub neej, kev tiv thaiv surge, thiab kev tiv thaiv ingress (IP65 / IP66) yog qhov tseem ceeb sib npaug. Hauv ntau qhov haujlwm, LED chips tseem tsis tau mus txog L70 thaum tus tsav tsheb ua tsis tiav.
Tsis tas li ntawd, B50 tsuas yog lub tswvyim nruab nrab xwb. Rau cov haujlwm uas xav tau kev ntseeg siab dua, kev saib xyuas ntau dua yuav tsum tau them rau L70 / B10 lossis L80 / B10-lub sijhawm uas tsuas yog 10% ntawm cov qauv tau poob qis dua tus nqi phiaj. Cov nuj nqis no muaj kev saib xyuas ntau dua li B50.
Yuav ua li cas kho cov kev ua neej nyob rau hauv kev sib tham ua lag luam
Qhov kev xav tsis zoo tshaj plaws yog cov neeg siv khoom pom "50,000 teev" thiab xav tias qhov teeb meem raug daws tas mus li. Hauv peb cov lus pom zoo peb ib txwm hais meej meej tias cov ntaub ntawv lub neej yog raws li LM-80 + TM-21 nyob rau hauv cov kev sib tshuam tshwj xeeb thiab qhov kub thiab txias; lub neej kev pabcuam tiag tiag yog sib koom ua ke los ntawm kev tswj xyuas thermal, tus neeg tsav tsheb, thiab kev ua haujlwm ib puag ncig; thiab ob qho tib si kev saib xyuas ntawm lub luminaire tiav thiab cov lus lav yuav tsum tau kuaj xyuas ua ke.
Cov kws tshaj lij muab cov ntawv qhia tag nrho LM-80 thiab daim ntawv suav TM-21 es tsis yog ib tus lej txaus nyiam. Qee cov tuam txhab lag luam tsuas yog thov "100,000 teev" yam tsis muaj kev txhawb nqa cov ntaub ntawv ntsuas sijhawm; cov lus thov no yuav tsum tau ceev faj.
Rau cov tswv thiab pab pawg engineering, ib txoj hauv kev siv tau ntau dua yog siv L70 / B50 raws li kev tsim qauv siv thaum xav tau lub sijhawm lav tsim nyog (feem ntau yog tsib xyoos lossis ntev dua) thiab qhia txog lumen- cov qauv luv nqi hauv daim ntawv cog lus. Qhov no muaj kev tiv thaiv zoo dua li tsuas yog caum daim ntawv hauv lub neej.
Lub neej tsis ntev yog ib qho ntawm cov ntsiab lus muag ntawm LED txoj kev teeb, tsis tau tsuas yog thaum txhais tau raug lawm lawv txhais ua ntev - lub sij hawm qhov project tus nqi . 50,000 teev tsis yog lus dab neeg; nws yog ib tug conditional projection. Ua raws li cov xwm txheej no rau qhov chaw ua haujlwm tiag tiag yog qhov tso cai rau tus lej los ua qhov tseeb.
Yog tias koj tab tom ntsuam xyuas txoj kev-teeb kev thov rau lub neej lossis xav tau los sib piv qhov kev ntseeg siab ntawm L70/B50 cov ntaub ntawv los ntawm cov tuam txhab sib txawv, thov koj xav qhia rau LM-80 cov lus ceeb toom lossis cov khoom specifications uas koj tau txais. Peb tuaj yeem pab koj tshawb xyuas seb qhov kev sim ntsuas puas txaus thiab seb qhov kev kwv yees puas tsim nyog, yog li koj tsis txhob raug dag los ntawm cov nuj nqis loj.
