Kev ntsuas ntsuas Lux Level
Cov qauv E = F x UF x MF / A rau illuminanceE (qee zaus denoted li kuv), nruab nrab lumens tus nqi los ntawm ib tug lightsource F (qee zaum Ll), coefficient ntawm kev siv UF (los yog Cu) thiab lub teeb pom kev zoo txij nkawm MF (lossis L.LF) thiab thaj tsam ib lub teeb A.
Kuj paub, kuv yuav paub pes tsawg qhov muag teev nyob hauv kuv chav?
Multiply dav ntawm chav x ntev chav x1.5 = tus nqi ntawm tag nrho yam tsawg kawg nkaus wattage xav tau (piv txwv li lub qab nthab yim feet). Faib los ntawm 60 kom tau qhov tus lej ntawm 60-wattequivalent qhov muag teev yuav tsum tau Tom qab ntawd, ntxiv cov wattage hauv txhua qhov noob nyob rau hauv txhua lub fixture rau xam seb pes tsawg leej yuav tsum tau lightfixtures.
Ib sab saum toj no, dab tsi yuav tsum tau qib qib nyob hauv kuv chav ua haujlwm? Qhov Pom Zoo thiab Pom Zoo Qib Sab Hauv Tsev Lub teeb sab nraum zoov qib yog kwv yees li 10,000 ua lux nyob rau hnub ntshiab. Nyob rau hauv lub tsev, nyob rau hauv lub cheeb tsam ze rau lub qhov rais, lub teeb qib yuav raug txo kom txog li 1,000 ua lux . Hauv nruab nrab thaj tsam nws yuav qis li 25 - 50 ua lux.
Qhov tseeb, qib lux yog dab tsi?
Lux . Cov ua lux (cim: lx) yog SIderived chav tsev ntawm illuminance thiab luminous emittance, ntsuas luminous flux ib chav tsev. Nws yog sib npaug rau ib lumen ib square meter. Hauv photometry, qhov no yog siv los ntsuas qhov kev siv, raws li pom los ntawm tib neeg lub qhov muag, ntawm lub teeb uas hits lossis dhau ntawm qhov chaw.
Lumen sawv rau dab tsi?
Cov lub lumen (cim: lm) yog SI derived unit ofluminous flux, ib qho kev ntsuas ntawm tag nrho cov muaj nuj nqis ntawm pom lightemitted los ntawm ib qhov chaw ntawm ib chav tsev ntawm lub sij hawm.
