Kom nkag siab CRI thiab lumen

Raws li nrog ntau lwm yam ntawm kev tshawb fawb xim, peb yuav tsum rov qab mus rau lub zog spectral faib ntawm lub teeb ci.
CRI yog xam los ntawm kev tshuaj xyuas cov spectrum ntawm lub teeb ci thiab tom qab ntawd simulating thiab sib piv cov spectrum uas yuav muaj kev cuam tshuam tawm ntawm cov qauv kuaj xim.
CRI xam lub hnub ci lossis lub cev dub SPD, yog li CRI siab dua qhia tias lub teeb pom kev zoo zoo ib yam li lub hnub ci ntuj (CCTs siab dua) lossis halogen / incandescent teeb pom kev zoo (CCTs qis dua).

Lub ci ci ntawm lub teeb ci yog piav qhia los ntawm nws cov zis luminaous, uas ntsuas hauv lumens. Ci ntsa iab, ntawm qhov tod tes, yog tag nrho tib neeg tsim! Nws yog txiav txim los ntawm lub wavelengths uas peb ob lub qhov muag yog rhiab tshaj plaws thiab tus nqi ntawm lub teeb lub zog nyob rau hauv cov wavelengths. Peb hu ua ultraviolet thiab infrared wavelengths "tsis pom" (xws li, tsis muaj qhov ci) vim tias peb lub qhov muag tsuas yog tsis "siv" cov wavelengths raws li kev pom qhov ci, txawm tias muaj zog npaum li cas hauv lawv.
Txoj Haujlwm ntawm Luminosity

Cov kws tshawb fawb nyob rau xyoo pua nees nkaum tau tsim cov qauv ntawm tib neeg lub zeem muag kom nkag siab zoo dua li cas qhov tshwm sim ntawm qhov ci ua haujlwm, thiab lub hauv paus ntsiab lus tom qab nws yog luminosity muaj nuj nqi, uas piav qhia txog kev sib raug zoo ntawm wavelength thiab kev nkag siab ntawm brightness.

Cov nkhaus daj sawv cev rau cov qauv duab ua haujlwm (saum toj no)
Lub luminosity nkhaus peaks ntawm 545-555 nm, uas sib haum mus rau ib tug txiv qaub-ntsuab xim wavelength ntau, thiab sai poob tawm ntawm siab dua thiab qis wavelengths. Critically, luminosity qhov tseem ceeb tsis tshua muaj siab tshaj 650 nm, uas sib haum mus rau xim liab wavelengths.
Qhov no txhais tau hais tias liab xim wavelengths, nrog rau xiav tsaus thiab violet xim wavelengths, tsis muaj txiaj ntsig ntawm kev ua kom pom qhov kaj. Ntsuab thiab daj wavelengths, ntawm qhov tod tes, yog qhov zoo tshaj plaws ntawm qhov ci ntsa iab. Qhov no tuaj yeem piav qhia yog vim li cas cov tsho tiv thaiv kev nyab xeeb thiab cov khoom tseem ceeb feem ntau siv cov xim daj / ntsuab kom ua tiav lawv qhov ci ci.
Thaum kawg, thaum peb piv cov luminosity muaj nuj nqi rau lub spectrum rau ntuj nruab hnub, nws yuav tsum paub meej tias yog vim li cas siab CRI, tshwj xeeb tshaj yog R9 rau liab, yog nyob rau hauv tsis sib haum xeeb nrog brightness. Lub fuller, wider spectrum yuav luag ib txwm muaj txiaj ntsig thaum nrhiav siab CRI, tab sis qhov nqaim spectrum tsom nyob rau hauv cov xim ntsuab-daj wavelength ntau yuav ua tau zoo tshaj plaws thaum nrhiav kev ua haujlwm siab dua.

Xim zoo thiab CRI yuav luag ib txwm tso tseg hauv qhov tseem ceeb hauv kev nrhiav kev siv zog rau qhov no. Yuav kom ncaj ncees, qee qhov kev siv, xws lisab nraum zoov teeb pom kev zoo, tej zaum yuav muab qhov tseem ceeb ntawm kev ua haujlwm ntau dua li kev ua xim xim. Kev nkag siab thiab kev txaus siab ntawm physics koom nrog, ntawm qhov tod tes, tuaj yeem muaj txiaj ntsig zoo hauv kev txiav txim siab paub hauv kev teeb pom kev zoo.
