Rau txhua qhov kev sib tw kis las kom ua tiav, kev ua kis las yuav tsum muaj teeb pom kev txaus. Lub TV tshaj tawm zoo nce ntxiv, cov neeg ncaws pob tau pom ntau dua, thiab cov neeg saib tau koom nrog ntau qhov kev sib tw.
Txij li cov teeb pom kev zoo ntawm LED tuaj yeem muab qhov tsim nyog teeb pom kev zoo thaum hmo ntuj lossis nyob rau hauv cov xwm txheej uas lub hnub ci ntuj tsis sib haum lossis tsis muaj, nws tau ua pov thawj tias yog ib qho kev xaiv zoo rau ob qho tib si sab hauv tsev thiab sab nraum zoov teeb pom kev zoo xyoo. Vim tias cov teeb ci LED muab qhov pom kev tsis tu ncua thiab teeb pom kev zoo thoob plaws hauv lub chaw ntau pob, lawv qee zaum txawm siv thaum nruab hnub.
Cov kev ua si yuav raug cuam tshuam los ntawm kev txhim kho cov teeb hauv chaw ntau pob nrog qhov tsis raug ntawm lumens, yog li koj yuav tsum tau ceev faj. Dab tsi yog qhov tseem ceeb ntawm kev xaiv cov lumens tsim nyog rau kev teeb pom kev hauv chaw ntau pob, yog li ntawd? Cov txheej txheem rau ntau yam kev ua si sib txawv li cas? Kom tau txais cov lus teb rau tag nrho koj cov lus nug, nyeem ntxiv.
Dab tsi txawv LUX los ntawm lumens hauvteeb pom kev hauv chaw ntau pob?
Peb yuav tsum xub qhia qhov txawv ntawm ob lub tswv yim no, uas yog ob qho tib si txuas nrog lub teeb pom kev zoo, ua ntej yuav mus rau hauv cov ntsiab lus uas yuav tsum tau coj mus rau hauv tus account thaum xaiv cov lumens tsim nyog rau lub teeb hauv chaw ua si. Lumens thiab lux yog dab tsi lawv yog.
Qhov ntau ntawm cov teeb pom kev zoo lossis qhov ci ntsa iab uas tsim los ntawm lub teeb los yog lwm yam teeb pom kev zoo yog hu ua lumen, feem ntau hu ua luminous flux. Nws hais txog qhov ntau ntawm illuminations generated los ntawm lub teeb pom kev zoo nyob rau hauv lub chaw ua si teeb pom kev zoo.
Ib qho lux yog ib chav ntsuas uas siv los piav txog lub teeb pom kev zoo lossis lub teeb ci. Nws yog sib npaug rau ib square meter ntawm lub teeb nto thaum muab tso rau ib 'meter' los ntawm tswm ciab. Nws sawv cev rau tag nrho qhov ntau thiab siv ntawm lub teeb thiab sib npaug rau ib lumen ib square meter.
Yog li, lub teeb nrog 1000 lumens tsom hauv ib square meter yuav muaj 1000 lux ntawm illumination. Yog tias tib lub teeb pom kev sib cais ntau tshaj tsib meters square, nws yuav tsim 200 lux.
Thaum xaiv cov teeb pom kev hauv chaw ntau pob, cov tswv yim no yog qhov tseem ceeb vim tias koj xav paub seb koj lub teeb pom kev zoo LED yuav zoo li cas thiab lub teeb yuav muaj zog npaum li cas. Txawm hais tias qhov ntau ntawm lumens nyob twj ywm tib yam, lub teeb pom kev zoo ntawm lub teeb yuav ci ntau dua.
Yuav tsum muaj pes tsawg Lumens rau teeb pom kev hauv chaw ntau pob?
Nws yog ib qho tseem ceeb kom nco ntsoov wattage thaum xam seb yuav tsum muaj pes tsawg lumensteeb pom kev hauv chaw ntau pob. Lub zog siv los tsim lub teeb, lossis lumens, yog hu ua watts. Yuav kom nrhiav tau tus nqi ntawm lumens xav tau rau qhov chaw ua si teeb pom kev zoo, koj yuav tsum suav qhov tsim nyog wattage thiab qhov ua tau zoo luminous.
LED teeb feem ntau muaj qhov ua tau zoo ntawm lumen ntawm 150 lm / W, tab sis koj kuj yuav tsum tau coj mus rau hauv tus account lub teeb 'lux vim tias lub teeb siv zog txo qis nrog kev ncua deb. Lub lumen efficiency, qhia nyob rau hauv lumens ib watt, yuav muab multiplied los ntawm tus nqi ntawm watts los txiav txim lub lumens. Cov qauv hauv qab no tuaj yeem siv los txiav txim qhov no:
Watts X (lm/W)=Lumens
Yog li ntawd, yog tias qhov ua tau zoo ntawm 1000W lub chaw ua si teeb yog 150 lm / W, koj yuav muaj 150,000 lumens.
Qhov chaw koj xav kom ci tuaj yeem siv los txiav txim seb yuav tsum muaj pes tsawg lumens. Piv txwv li, koj tuaj yeem sib ntxiv ob qho tib si kom txiav txim siab tus nqi ntawm lumens yog tias lub chaw ntau pob yog 100 square metres loj thiab 300 lux yuav tsum tau. Hauv qhov no, 30,000 lumens yuav xav tau.
