Qhov txawv ntawm Lumens thiab Watts
Nrog kev nce ntawm lub zog- siv lub teeb pom kev zoo zoo li LEDs, xaiv lub teeb lub teeb raws li watts nkaus xwb- uas ntsuas kev siv hluav taws xob - tsis ua rau muaj kev nkag siab ntxiv lawm. Hloov chaw,lumenstau dhau los ua qhov kev ntsuas tseem ceeb rau kev ntsuas qhov ci.
Rau cov qhov muag teev incandescent, ntau dua wattage feem ntau txhais tau tias lub teeb ci dua. Nrog LEDs, txawm li cas los xij, tsis muaj kev sib raug zoo ntawm watts thiab lub teeb tso zis. Lumens ntsuas tag nrho pom lub teeb, los yog ci: qhov siab dua tus nqi lumen, lub teeb ci dua. Xav txog nws zoo li nkas loos rau mis nyuj- nws yog hais txog qhov ntau, tsis yog lub zog.
Tsoomfwv Meskas Lub Tsev Haujlwm Saib Xyuas Kev Lag Luam tam sim no xav kom cov tuam txhab teeb pom kev zoo kom pom cov lumens tseem ceeb ntawm kev ntim khoom, nrog rau kwv yees cov nqi hluav taws xob txhua xyoo thiab kev ua neej nyob. Raws li lub zog- txuag qhov muag teev ua lag luam, lumens tsis tu ncua hloov watts raws li tus qauv ntsuas ntawm qhov ci. Hauv qab no yog ib qho dav dav watt-rau- lumen conversion daim ntawv raws li cov tsoos incandescent qij, pab tau thaum hloov mus rau LEDs:
150W → approx . 2600 lm
100W → approx . 1600 lm
75W → approx. 1100 lm
60W → approx . 800 lm
40W → approx . 450 lm
25W → approx. 200 lm
Nws tseem yog ib qho tseem ceeb uas yuav tsum nco ntsoov tias ntau lub teeb pom kev hauv tsev thiab kev lag luam tau tsim los rau cov qij taws thiab tej zaum yuav suav nrog cov ntawv xws li "Max XXX Watts." Cov lus ceeb toom no xa mus rau cov kev txwv cua sov es tsis yog qhov ci. Txij li thaum LED qhov muag teev ua haujlwm ntawm qhov qis dua wattages thiab tsim kom muaj cua sov tsawg, LED qhov muag teev npe "sib npaug rau 60W" tuaj yeem siv nyab xeeb rau hauv cov khoom ntsuas rau 40W incandescent noob.
