Teeb pom kev zoo yog ntau tshaj qhov ci ntsa iab; nws kuj yog hais txog qhov hnov ntawm lub teeb ntawd. Cov xim xim, uas yog txiav txim los ntawm CCT (Correlated Color Temperature), yuav ua rau ib qho chaw nrog tib lub teeb pom kev zoo los yog xis nyob. CCT txiav txim seb lub teeb zoo li sov, nruab nrab, lossis txias thiab ntsuas hauv Kelvin (K).
Teeb pom kev zoo nrog CCT tau pom tias ua kom lub siab xav, txo qhov muag pom, thiab ua kom cov khoom tsim tau. Cov suab nrov txias (5000K–6500K) tau cuam tshuam nrog kev ceeb toom thiab kev saib xyuas, thiab US Lub Tsev Haujlwm Saib Xyuas Hluav Taws Xob hais tias teeb pom kev zoo tuaj yeem txhim kho kev ua haujlwm txog li 16%.
Paub txog CCT ua rau koj txiav txim siab zoo dua rau kev nplij siab, ua haujlwm tau zoo, thiab pom qhov pom tseeb txawm tias koj tab tom hloov kho qhov chaw ua haujlwm teeb pom kev zoo, tsim lub khw muag khoom, lossis teeb pom kev hauv chaw nyob. Lub ntsiab lus ntawm CCT, nws qhov ntsuas, thiab cov ntawv thov tsim nyog rau txhua qhov xim kub yog tag nrho nyob rau hauv phau ntawv no.
CCT hauv Teeb pom kev zoo yog dab tsi?
Cov xim zoo nkauj ntawm lub teeb dawb tso tawm los ntawm lub teeb ci yog ntsuas hauv Kelvin (K) thiab raug xa mus rau CCT (Correlated Color Temperature). Nws cuam tshuam qhov chaw zoo li cas thiab tshwm sim los ntawm kev qhia seb lub teeb txias (xiav tones), nruab nrab, lossis sov (daj / liab tones).
Cia peb faib nws mus rau hauv nws cov khoom tseem ceeb tshaj plaws kom nkag siab tias CCT cuam tshuam li cas rau kev tsim teeb pom kev zoo thiab tib neeg kev xav:
Ntsuas hauv Kelvin (K):Qhov ntsuas qhov sib txawv ntawm 1000K txog 10,000K, txawm hais tias feem ntau cov teeb pom kev zoo siv poob ntawm 2200K thiab 6500K.
Lub teeb sov (2200K-3000K):Ua ib qho muag muag, daj daj zoo tagnrho rau cozy, so qhov chaw xws li chav pw lossis tsev noj mov.
Neutral Dawb (3500K-4000K):Cov suab nrov sib npaug siv hauv chaw ua haujlwm, khw muag khoom, thiab chav ua noj kom huv, zoo nkauj.
Lub teeb txias (5000K-6500K):Ci ntsa iab thiab xiav, siv hauv tsev kho mob, studios, thiab kev ua haujlwm - hnyav ib puag ncig kom pom tseeb thiab ua kom pom tseeb.
Tsis muaj feem xyuam rau brightness:CCT cuam tshuam cov xim xim, tsis yog lub teeb pom kev zoo li cas (uas yog ntsuas hauv lumens).
Keeb Kwm thiab Kev Tshawb Fawb Hauv qabXim kub
Txoj kev tshawb fawb txog hluav taws xob ntawm lub cev dub nyob rau xyoo 19th - lub xyoo pua physics yog qhov uas lub tswv yim ntawm cov xim kub tau tshwm sim thawj zaug. Gustav Kirchhoff, tus kws kho mob, thawj zaug tau tshaj tawm lub tswv yim ntawm lub cev dub zoo meej hauv xyoo 1860. Txoj cai lij choj blackbody hluav taws xob, uas Max Planck tau tsim nyob rau xyoo 1900, piav qhia txog yuav ua li cas cov khoom siv hluav taws xob tso tawm lub teeb uas hloov xim los ntawm liab mus rau dawb mus rau xiav thaum kub nce.
Lub Kelvin nplai, lub npe hu ua Tswv Kelvin (William Thomson), tau tsim los ntawm qhov kev tshawb pom no thiab tau los ua txoj kev lees paub rau kev txiav txim siab xim kub. Kev lag luam teeb pom kev zoo tau pib siv Correlated Colour Temperature (CCT) los qhia qhov pom lub suab ntawm lub teeb dawb raws li lub teeb pom kev zoo tau hloov los ntawm qhov muag teev hauv xyoo 1870 mus rau cov teeb fluorescent hauv xyoo 1930s thiab LEDs hauv xyoo 1960s.
CCT tam sim no yog tus yam ntxwv tseem ceeb rau kev tsim teeb pom kev zoo thiab xaiv hauv kev lag luam, kev lag luam, thiab chaw nyob.
CCT ntsuas li cas?
Los ntawm kev sib piv cov xim ntawm lub teeb ci rau lub teeb uas tsim los ntawm qhov zoo tshaj plaws blackbody radiator ntawm qhov kub thiab txias, CCT tau qhia hauv Kelvin (K). Qhov tshwm sim qhia tau hais tias seb lub teeb pom tau los ntawm tib neeg lub qhov muag li sov, nruab nrab, lossis txias.
Cov kws tshaj lij teeb pom kev zoo siv cov cuab yeej photometric hauv kev tswj xyuas kom paub tseeb qhov no. Lub spectroradiometer, uas tshuaj xyuas lub teeb qhov chaw lub spectrum fais fab faib (SPD), yog cov cuab yeej siv feem ntau. Lub Planckian locus, ib qho nkhaus ntawm daim duab chromaticity uas qhia txog cov xim ntawm lub teeb tawm los ntawm lub cev dub tiag tiag ntawm qhov kub sib txawv, tom qab ntawd qhia tawm tsam cov ntaub ntawv no.
Lub teeb qhov chaw Correlated Colour Temperature yog txiav txim los ntawm qhov ze ze nws cov xim sib tw rau qhov taw tes ntawm qhov nkhaus no. Piv txwv li, qhov sib tw ze rau 2700K, piv txwv li, txhais tau tias sov dawb lub teeb, tab sis ib qho ze rau 6500K qhia tias lub teeb txias dawb lossis nruab hnub. Feem ntau ntawm cov khoom lag luam teeb pom kev zoo siv nyob nruab nrab ntawm 2200K txog 6500K ntau yam.
Kev siv CCT hauv Kev Tsim Teeb Pom Kev

2. Teeb pom kev zoo rau kev lag luam
3500K txog 4500K yog nquag siv hauv khw muag khoom thiab chaw ua haujlwm vim tias nws muab qhov pom tseeb dua thiab txhim kho xim pom kev, ob qho tib si tseem ceeb rau kev nthuav qhia thiab cov khoom. Lub teeb dawb nruab nrab yog qhov tshwj xeeb hauv cov chaw ua haujlwm vim nws txhawb kev saib xyuas yam tsis muaj glare.
3. Kev kho mob thiab kev lag luam ib puag ncig
Cov teeb pom kev zoo ib txwm muaj rau cov chaw tsim khoom, chaw sim, thiab tsev kho mob yog txias dawb rau nruab hnub (5000K-6500K). Cov suab nrov no txhim kho cov khoom tsim tau, pom tseeb, thiab nthuav dav, tshwj xeeb tshaj yog rau cov dej num uas hu rau qhov tseeb.
4. Teeb pom kev sab nraud
Toj roob hauv pes teeb pom kev zoo, chaw nres tsheb, thiab cov teeb pom kev zoo siv ntau yam ntawm 3000K txog 5000K, nyob ntawm seb qhov ci ci lossis qhov sov sov yog qhov tseem ceeb dua. Sab nraum zoov kev ruaj ntseg siv hnub ci LEDs vim lawv qhov sib txawv thiab ci ntsa iab.
CCT cuam tshuam li cas rau lub neej txhua hnub
CCT muaj kev cuam tshuam rau koj lub siab, kev tsim khoom, thiab muaj peev xwm ua kom tsis muaj zog. Koj qhov kev nplij siab, lub zog, thiab lub siab xav tuaj yeem cuam tshuam los ntawm cov xim ntawm koj lub teeb pom kev zoo.
