Ua qhov brighternuv ntses teeb, qhov zoo dua cov nyhuv ntses?
Ua ntej peb nkag mus rau hauv qhov ntawd, cia peb tham me ntsis txog qhov ci ntsa iab thiab illuminance.
Luminance yog hais txog lub cev kom muaj nuj nqis ntawm luminance (reflection) siv ntawm qhov chaw ntawm lub cev luminous (reflector).Tib neeg lub qhov muag pom lub teeb ci los ntawm ib qho kev taw qhia, thiab qhov sib piv ntawm lub teeb ci hauv qhov kev taw qhia no rau thaj tsam ntawm lub teeb ci "pom" los ntawm tib neeg lub qhov muag txhais tau tias yog chav tsev ci ntsa iab ntawm lub teeb ci, uas yog, luminous siv ntawm chav tsev projected cheeb tsam.Chav tsev ntawm qhov ci yog Candela ib square meter (cd / m2).Brightness yog ib tug neeg txoj kev xaav ntawm qhov siv ntawm lub teeb.Nws yog ib tug subjective kom muaj nuj nqis.Thaum tham txog lub ntsiab lus ntawm lub teeb ntses, vim tias lub teeb tsuas yog tsom rau ntawm qhov muag ntses, kuv xav tias nws tsis tsim nyog siv qhov ci los ntsuas.1500w hlau halide nuv ntses teeb.Hloov chaw, peb yuav tsum siv hluav taws xob ci, lossis radiance luv luv.
Radiation luminance yog ib lub cev muaj nuj nqis uas sawv cev rau cov hluav taws xob siv hluav taws xob ntawm qhov taw tes ntawm qhov chaw hluav taws xob saum npoo ntawm ib qho kev taw qhia.Hais txog lub zog hluav taws xob los ntawm cov hluav taws xob hluav taws xob nyob rau hauv cheeb tsam cheeb tsam thiab chav tsev khoom Lub kaum sab xis los ntawm lub dav hlau ntsug lub cev ib txwm coj hauv chav tsev lub sij hawm, uas yog, cov hluav taws xob hluav taws xob ntawm cov hluav taws xob hluav taws xob ntawm chav tsev projected cheeb tsam thiab chav tsev khoom Angle.Chav tsev yog watts / (spheroidium m2)
Illuminance feem ntau yog hais txog qhov siv ntawm lub teeb, uas yog hais txog qhov flux ntawm pom lub teeb tau txais ib cheeb tsam thiab ntsuas hauv Lux lossis Lx.Thaum lub luminous flux tshaj ib cheeb tsam ntawm 1 square meter yog 1 lumen, nws illuminance yog 1 lux.Luas = 1 Lm/m2.Obviously, lub tswv yim ntawm illumination kuj yog raws li lub subjective perception ntawm tib neeg lub qhov muag.Thaum ntsuashlau halide squid nuv ntses teeb, radiant illumination yuav tsum tau siv.Radiant illuminance, tseem hu ua irradiance, yog lub radiant flux ntawm chav tsev ntawm qhov chaw raug, hauv watts ib square meter (W / square meters).Txawm li cas los xij, cov ntaub ntawv tshawb fawb tam sim no ntawm phototaxis ntawm cov ntses feem ntau yog nyob ntawm qhov pom kev cuam tshuam rau tib neeg lub zeem muag.Hauv qhov kev sib tham no, cov ntaub ntawv thiab cov chav nyob cuam tshuam txog tib neeg lub zeem muag tseem siv tau, uas yuav tsum tau kho kom raug raws li lub wavelength thiab lwm yam hauv kev siv tiag tiag.
Feem ntau hais lus, feem ntausiab watt underwater nuv ntses teebhmo ntuj qhov teeb pom kev zoo tsis ntau tshaj 20Lux, illumination ntau tshaj 0.01Lux yog txaus nyiam rau ntses.Yog hais tias 30% ntawm lub teeb ntawm lub teeb halogen yog illuminated ntawm lub hiav txwv, ces ib nrab ntawm lub teeb tuaj yeem nkag mus rau hauv dej xav txog lub kaum sab xis.Tag nrho cov naj npawb ntawm lumens nyob rau hauv lub teeb system ntawm lub nkoj yog hais txog 21 trillion lumens, uas txhais tau hais tias tus naj npawb ntawm1000 watt hlau halide teebyog hais txog 200 mus rau 300. Txuas ntxiv kom muaj ntau lub teeb nuv ntses, txhim kho qhov ci ntsa iab ntawm lub nkoj teeb, txhawm rau txhim kho cov nyhuv ntawm kev sau ntses yog tsis pab ntau !!(tshwj tsis yog lub hwj chim thiab tus naj npawb ntawm cov teeb tau nce nyob rau tib lub sijhawm, tsa qhov siab ntawm lub teeb dai).
Cov shoals kwv yees nyob qhov twg?Yog tias lub teeb tag nrho rau ntev txaus, cov ntses yuav nyob deb li ntawm 100 meters deb thiab feem ntau yuav tsis los ze dua.
Qhov tshwm sim ntawm kev sib tham ntawm lub ntsiab lus thib ob: tag nrho cov lumens ntawm lubteeb lub nkoj teebsystem yog hais txog 21 trillion lumens, uas yog, tus naj npawb ntawm 1000W kub halide teeb yog hais txog 200-300.Txuas ntxiv mus ntxiv cov ntses teeb, txhim kho lub ci ci ntawm lub nkoj teeb, txhawm rau txhim kho cov nyhuv ntawm cov ntses sau yog tsis pab ntau !!(tshwj tsis yog ua kom lub zog thiab muaj pes tsawg lub teeb nyob rau tib lub sijhawm, tsa qhov siab ntawm lub teeb dai, thiab hloov lub kaum sab xis ntawm lub teeb dai).
