Color Rendering Index txhais li cas?
Xim Rendering Index yuav tsum tsis txhob totaub nrog cov xim kub ntawm lub teeb ci. Cov xim kub yog xam nyob rau hauv Kelvin thiab qhia tau hais tias txias los yog sov lub teeb pom kev zoo. Hloov pauv, CRI tsawg dua nyob ntawm qhov hloov pauv no. Rau ntau qhov chaw thiab tib neeg, qhov ntau dua CRI, qhov zoo dua cov xim rendering peev xwm.
Xim Rendering Index yog dab tsi? CRI yog qhov ntsuas qhov tseeb ntawm qhov teeb pom kev zoo li cas qhia cov xim ntawm cov neeg lossis cov khoom hauv qab lawv. Nrog kev pab los ntawm tus lej ntsuas los ntawm 1 txog 100, CRI ntsuas cov xim hloov thiab qhov tseeb ntawm cov khoom sib txawv ntawm qhov sib txawv ntawm cov khoom ntawd yuav tshwm sim hauv qab ntuj tshav ntuj lossis teeb pom kev zoo.
Dab tsi yog tus nqi CRI zoo rau lub teeb ci?
Raws li peb paub tias cov xim rendering Performance index yog ntsuas ntawm qhov ntsuas ntawm {{0}} thiab 100. Ntawm 0 CRI, tag nrho cov xim tshwm tib yam thaum lub 100 CRI qhia cov xim tiag tiag ntawm cov khoom. Halogen teeb thiab incandescent teeb muaj CRI ntawm 100. Feem ntau, cov teeb pom kev zoo nrog s VRI qhov tseem ceeb ntawm 80 thiab 90 yog suav tias yog qhov zoo thiab cov uas muaj ntau tshaj 90 CRI qhov tseem ceeb yog qhov zoo heev. Koj tuaj yeem ua raws li txoj cai yooj yim piv txwv li qhov siab dua tus nqi CRI, qhov zoo dua qhov muaj peev xwm ua rau xim.
Tsis muaj kev sib txuas ntawm CRI thiab xim kub. Ob leeg yog cov khoom sib txawv thiab muaj kev ywj pheej ntawm ib leeg. Piv txwv li, 5000K fluorescent teeb qhov chaw xws li nruab hnub nrig xim kub tuaj yeem muaj CRI ntawm 90 thaum lwm qhov 5000K fluorescent teeb tuaj yeem muaj CRI ntawm 75.
Vim li cas cov xim rendering Performance index tseem ceeb?
CRI yog qhov tseem ceeb hauv yuav luag txhua qhov chaw xws li koj lub tsev mus rau koj qhov chaw ua haujlwm. Lub teeb pom kev zoo nrog tus nqi qis CRI yuav coj ntxuav tawm thiab cov xim tiaj tus rau cov khoom nws teeb pom kev zoo. Thaum nws ntog rau ntawm cov khoom, lawv saib dull thiab drab-xim. Rau tib neeg, nws tsuas yog txhais tau tias mob tawv nqaij tones thiab lub qhov muag tsis muaj sia.
Ntawm qhov tod tes, lub teeb pom kev zoo nrog tus nqi CRI siab tuaj yeem ua rau lub neej phem thiab zoo siab hauv koj lub ambience. High Colour Rendering Index yuav pop cov xim ntawm koj cov khaub ncaws, rooj tog, khoom noj, thiab tag nrho lwm yam khoom nyob ib puag ncig, ntxiv cov nplua nuj delicacy rau cov qauv tsim koj tau teeb tsa. Lub teeb pom kev zoo nrog CRI siab yuav ua rau cov neeg muaj lub ntsej muag zoo nkauj thiab nplua nuj ntawm daim tawv nqaij.
Tus nqi CRI siab yog qhov tseem ceeb tshwj xeeb rau cov xim-tseem ceeb ib puag ncig uas qhov kev nthuav qhia, kev pom kev pom, thiab qhov tseeb xim yog qhov tseem ceeb rau kev lag luam. Qhov no suav nrog cov khw muag khoom noj los pab ua kom cov zaub mov zoo txaus siab, cov khw muag khoom kom pom cov khaub ncaws zoo nkauj, thiab hauv lub xeev tiag tiag thaum tsim kom muaj kev txaus siab thiab zoo nkauj rau lub tsev muag nws.
CRI thiab LED qhov muag teev
Tsis ntev los no, LED qhov muag teev tau nce qhov chaw, feem ntau vim lawv lub zog ua haujlwm thiab lub teeb ci ci. Feem ntau ntawm LED teeb muab CRI Xim Rendering Index tus nqi ntawm 80 txog 90 ntawm qhov ntsuas. Raws li qhov tshwm sim, LED tsim ib chav ci dua tab sis nrog qhov tseeb thiab ntuj tso tawm ntawm lub teeb. Contrary to fluorescent teeb qhov muag teev uas yuav ua tau ib tug unnatural saib, LEDs yog zoo suited rau sab hauv tsev. Dhau li ntawm CRI, tus naj npawb ntawm lumens tso zis lossis lub teeb tiag tiag tsim ua lub luag haujlwm tseem ceeb hauv kev ua tau zoo tag nrho ntawm LED teeb lub teeb ib yam nkaus.
xim rendering index
Vim li cas Xim Rendering Index tseem ceeb dua?
Thaum lub hnub nyoog ntawm incandescent teeb qhov chaw, cov xim rendering Performance index tsis yog ib qho zoo kawg nkaus li cov qhov muag teev incandescent muab cov xim zoo nkauj. Tom qab ntawd lub sij hawm los txog thaum lub qhov muag teev incandescent pib ploj ntawm qhov chaw vim lawv lub zog tsis zoo. Thaum pib, lawv tau hloov los ntawm cov teeb fluorescent uas muaj zog ntau dua. Niaj hnub no, LED qhov muag teev tau dhau los ua kev hloov pauv mus rau lub teeb fluorescent.
LED qhov muag teev tau raug qhuas rau lawv cov kev siv zog ntau dua txawm tias qhov sib txawv ntawm cov hluav taws xob fluorescents. Xws li cov teeb pom kev zoo kuj tuaj nrog lwm yam zoo xws li lub neej ntev. Tsis tas li ntawd, lawv tsis muaj teeb meem mercury thiab tsis tawg. Yog li cov teeb pom kev zoo hloov pauv ntawm fluorescent mus rau LEDs yog vim li cas CRI tseem ceeb hauv kev teeb pom kev zoo.
