Nyob rau hauv tag nrho kuv lub xyoo nyob rau hauv txoj kev teeb export, lumen tso zis yog ib tug tseem ceeb parameter uas tshwm sim nyob rau hauv yuav luag txhua txhua inquiry daim ntawv thiab technical spec - thiab nws kuj yog ib qho ntawm feem ntau qhov chaw ntawm kev tsis sib haum xeeb thaum kuaj thiab tom qab- muag. Qee cov neeg siv khoom sib piv lawv cov txiaj ntsig kev sib koom ua ke nrog cov txiaj ntsig ntawm lumen tus nqi luam tawm ntawm daim ntawv qhia khoom, pom qhov tsis sib xws, thiab nug tam sim ntawd seb cov khoom puas tsis phim cov lus qhia. Cia peb taug kev los ntawm qhov teeb meem lumen sib txawv no kom raug, sib txuas cov qauv ntsuas kev lag luam nrog -kev coj ua hauv ntiaj teb, kom paub meej tias qhov sib txawv ntawm qhov sib txawv yog qhov tsim nyog.
Vim li cas Rated Lumen Output thiab Measured Lumen Output txawv
Ua ntej, nws yog ib qho tseem ceeb kom nkag siab tias tus nqi lumen feem ntau yog qhov theoretical luminous flux ntsuas los ntawm cov chaw tsim khoom chip lossis fixture Hoobkas raws li cov qauv ntsuas, ntawm qhov tshwj xeeb tam sim no thiab qhov hluav taws xob. Thaum ib yam khoom ua tau los ntawm kev sib dhos, qhov kho qhov muag tiv thaiv kev cuam tshuam, thiab kev teeb tsa lub dab dej kub, qee qhov kev poob qis ntawm cov luminous flux yog qhov kev zam tsis tau - qhov no yog qhov lees paub dav dav, ib txwm tshwm sim thoob plaws hauv kev lag luam, tsis yog pov thawj ncaj qha ntawm qhov teeb meem zoo. Kev nkag siab qhov no yog qhov tseem ceeb rau kev txiav txim siab seb qhov kev sib txawv ntawm qib twg yog qhov tsim nyog piv rau qhov ua tau qhia qhov teeb meem zoo.
Dab tsi Deviation Range tau txais dav hauv kev lag luam
1. Ib qho kev sib txawv hauv ± 10% feem ntau suav hais tias txais tau
Raws li peb cov kev paub dhau los nrog ntau qhov kev lees paub thoob ntiaj teb thiab cov neeg siv tshuaj xyuas ntau xyoo, kev lag luam feem ntau lees txais qhov sib txawv ntawm lumen ntawm li ± 10%. Hauv lwm lo lus, rau txoj kev teeb pom kev zoo nyob ntawm 5000 lumens, qhov ntsuas qhov tseeb nyob qhov twg ntawm 4500 thiab 5500 lumens feem ntau poob rau qhov kev hloov pauv ib txwm thiab tsis yog qhov teeb meem zoo.
2. Qee cov qauv nruj dua yuav tsum muaj kev sib txawv hauv ± 5%
Rau qee qhov siab -txoj haujlwm hauv nroog lossis cov neeg siv khoom lag luam - tshwj xeeb yog qee qhov tseemfwv kev muag khoom hauv Tebchaws Europe thiab Asmeskas - cov kev qhia tshwj xeeb qhia meej tias yuav tsum muaj luminous flux sib txawv los tswj hauv ± 5%. Cov phiaj xwm ntawm qib no xav tau kev tswj xyuas nruj dua ntawm cov nti sib xws, kho qhov muag pom kev zoo, thiab tag nrho cov khoom sib dhos zoo, thiab cov khoom siv tau zoo dua qub. Cov ntsiab lus no yuav tsum tau sib tham kom meej nrog tus neeg siv khoom ntawm cov lus hais, kom tsis txhob muaj kev tsis sib haum xeeb tom qab los ntawm qhov kev cia siab tsis sib haum nyob ib puag ncig tus qauv siv.
3. Daim Ntawv Qhia Kev Xeem LM-79 yog cov ntaub ntawv tseem ceeb
Txawm hais tias tus qauv sib txawv siv li cas, seb tus nqi lumen puas tau raws li qhov yuav tsum tau txiav txim siab raws li LM-79 daim ntawv tshaj tawm kev xeem tawm los ntawm peb lub koom haum kuaj thib peb - tsis yog qhov ntsuas tus nqi luam tawm ntawm daim ntawv qhia khoom. LM-79 yog txoj kev sim tsim los ntawm Illuminating Engineering Society of North America (IESNA) rau kev ntsuas hluav taws xob thiab kev ua haujlwm ntawm cov teeb pom kev zoo ntawm LED luminaires tiav. Daim ntawv tshaj tawm qhia meej meej cov ntaub ntawv ntsuas tseem ceeb - qhov tseeb luminous flux, luminous efficiency, thiab CRI - thiab nws yog ib qho ntawm cov ntaub ntawv tsim nyog uas feem ntau xav tau ntawm cov neeg muag khoom ntawm kev sib tw thoob ntiaj teb.
Feem ntau ua rau ntau dhau lumen sib txawv
1. Chip Quality tsis sib haum ntawm qhov chaw
Yog tias cov chips tuaj yeem tsis dhau los ntawm kev nruj nruj, cov yam ntxwv ntawm cov luminous decay thiab thawj luminous flux tuaj yeem sib txawv ntawm cov chips siv nyob rau hauv tib lub batch ntawm fixtures, ncaj qha ua rau cov khoom tiav lawm cov lumen tso tawm kom fluctuate tshaj qhov tsim nyog ntau yam. Qhov no yog vim li cas peb pom zoo kom txheeb xyuas cov khoom tsim nyog ntawm cov khoom tsim nyog thiab cov ntaub ntawv xeem thaum lub sijhawm muab khoom.
2. Optical Lens Distribution Losses
Lub lens tsis zoo tsim kho qhov muag thib ob, lossis cov khoom siv lens nrog cov teeb pom kev tsis zoo, ua rau cov luminous flux poob ntxiv thaum lub teeb kis tau tus mob, ntxiv qhov sib txawv ntawm txoj kev tiag tiag - pom qhov pom kev thiab qhov theoretical lumen tus nqi. Qhov no kuj yog ib qho laj thawj cov khoom lag luam nrog tib lub lumen daim duab tuaj yeem pom qhov sib txawv ntawm cov teeb pom kev zoo nyob ntawm cov chaw tsim khoom.
3. Tsis zoo cua sov Dissipation Design Accelerates Lumen Depreciation
Kev khiav hauj lwm kub ntawm lub teeb ci LED ncaj qha cuam tshuam tus nqi ntawm lumen depreciation. Cov khoom siv hluav taws xob tsis zoo los yog cov khoom siv thermal xaiv tsis raug tuaj yeem ua rau lub teeb pom kev zoo kom poob qis tom qab lub sijhawm ua haujlwm. Hom kev sib txawv no feem ntau tsis tuaj yeem kuaj pom thaum pib lub Hoobkas tshuaj xyuas - nws yuav tsum tau soj ntsuam nrog ntev -cov ntaub ntawv kuaj xyuas lumen.
Xaus
Kev lag luam feem ntau lees txais qhov sib txawv ntawm ± 10% nruab nrab ntawm txoj kev teeb pom kev zoo thiab cov txiaj ntsig lumen tso tawm, nrog rau cov haujlwm nruj dua yuav tsum muaj nyob rau hauv ± 5%, thiab LM-79 daim ntawv xeem thib peb yuav tsum yog qhov siv rau kev txiav txim. NtawmLuxsky Teeb pom kev zoo, peb tuav tswj nruj tshaj nti binning, kho qhov muag tis, thiab tshav kub dissipation tsim, ua kom lumen sib txawv tsis tu ncua nyob rau hauv ib tug tsim nyog ntau yam. Xav tias dawb hu rau peb pab neeg rau cov ntawv xeem thiab cov lus pom zoo ntawm cov khoom.
