Dab tsi yog CRI R9 thiab vim li cas nws tseem ceeb?

Cri R9 yog aKuaj cov qauv xim(TCS) Siv nyob rau hauv kev sib tham ntawm ncua Cri. Ntau cov tuam ntxhab yuav ib leeg qhia tawm cov dav dav, rho tawm lubCri R9 tus nqiCov. Cri R9 yog ib txwm muaj cov qauv ntxiv rau cov medication rau kev ntsuas lub peev xwm ntawm cov xim muaj peev xwm, tshwj xeeb hais txog lub zog uas muaj cov wavelength.
Qhov kev kuaj pom ntawm kev xam ntawm R9, ua ke nrog nws cov qauv kev xeem cov xim (TCS9), feem ntau yog qhia kom nkag siab txog cov xim zoo ntawm lub teeb pom kev zoo ntawm lub teeb ci.

Dab tsi yogCri r9Tus nqi?

R9 yog cov metric uas qhia tau tias kev ncaj ncees ntawm lub teeb ci hauv kev tshaj tawm cov xim liab liab.
"Muaj tseeb" yog tus cwj pwm raws li lub hnub nruab hnub lossis mobqhov muag teev, credent raws li cov xim kub.
Tus nqi R9 yog txiav txim siab los ntawm kev suav cov xim uas cuam tshuam los ntawm cov khoom siv tcstrance raws li TCS9, zoo sib xws rau txhua tus ntawm CRI R qhov tseem ceeb.
Lub TCS9 Spectrum yog feem ntau muaj teeb liab liab. Nyob rau hauv cov nqe lus ntawm spectrum, peb soj ntsuam qhov no li wavelengths tshaj 600 nm.
Qhov no qhia tau tias tsis muaj lub teeb liab txaus nyob rau hauv lub teeb ci yuav ua rau cov xim liab yuav ua rau muaj kev cuam tshuam lossis hloov pauv.
TusLED cov khoom pov thawjIb qho tseem ceeb tsis txaus ntawm liab lub teeb pom kev ntawm wavelengths tshaj 600 nm.
CRI R9 Rating rau qhov no LED yog -1. 4. (Tseeb, tus lej tsis zoo!) Qhov no tshwm sim txawm tias yog cov dav hlau cri (RA) yog 79.
 

Dab tsi yog qhov tseem ceeb ntawm Cri R9?

Cri R9 yog qhov tseem ceeb tshaj plaws, ua haujlwm muaj peev xwm ua tau cov ntsiab lus liab, qhov tseeb tsis pom los ntawm kev kwv yees ntawm CRI.
Nyob rau hauv cov ntsiab lus ntawm cov bonder cri ra cov txheej txheem, ibLED kev nthuav tawmCov xim liab xim liab tseem tau txais 80 CRI (RA).
Kev tshuaj ntsuam ntawm R9 tus nqi, txawm li cas los xij, qhia tau tias lub teeb yuav ua rau pom kev ua haujlwm sab nrauv liab rau cov nyom liab tshwj xeeb.

 

Dab tsi ua ib qho kev lees paub CRI R9?

Thaum tus nqi siab tshaj plaws ntawm R9 kuj yog 100, nws yuav tsum tau ntsuas me ntsis dua li cov nqi nruab nrab.
Kev ua lej, R9 nthuav tawm qhov nyuaj ntau dua hauv kev nce qib siab rau kev siv tus nqi siab thiab ua rau pom cov kev hloov pauv rau kev hloov pauv. Tus qhab nia R9 ntawm 50 lossis siab dua yog suav tias "zoo," whereas tus qhab nia ntawm 90 lossis ntau dua yog suav tias yog "zoo heev."
Thiaj li, koj yuav pom tias feem ntau ntawm cov khoom lag luam teeb pom kev zoo ntawm kev ua lag luam tsis tshua xeev lub xeevR9 tus nqi, thiab thaum lawv ua, lawv tsis tshua paub tseeb tus nqi tshaj 50. Peb tsis paub tseeb tias ib tus nqi ntau tshaj R9> 95 vim qhov kev rhiab no.
Qhov no tshwm sim vim tias CRI siv cov CIKE UV chaw, uas yog distorted rau kom ua xim xim hauv seem liab hauv ntu kev ua yeeb yam li cas hauv lub chromaticity. Raws li cri ntsuas cov xim tsis sib xws ntawm lub qhov teeb pom kev zoo ntawm lub hauv paus thiab siv cov khoom siv xim tsis sib xws yuav ua rau muaj kev txo qis dua ntawm r tau.

 

Dab tsi ua rau liab xim?

Liab yog Hawj txawm tseem ceeb rau ntau yam kev siv, suav nrog kev yees duab, textiles, thiab kev sawv cev ntawm tib neeg lub suab nrov.
Ntau yam uas tsis tshwm sim ib tug liab hue yog, qhov tseeb, ib qho sib thooj, ib qho khoom sib xyaw ua ntau yam xim, suav nrog liab. Daim tawv nqaij tawv tau cuam tshuam ntau dua los ntawm cov ntshav liab qab ntawm cov ntshav hauv qab daim tawv nqaij.
Yog li, lub teeb devoid ntawm liab yuav muab ib tus neeg tshwm sim daj ntseg los yog txawm Greenish. Qhov no yuav muaj cov kev cov nyom rau cov ntawv thov kev kho mob uas muaj kev nkag rau xim yog qhov tseem ceeb rau kev kuaj mob. Hauv cov teb zoo li yees duab, zoo nkauj zoo yog qhov tseem ceeb tshaj plaws thiab feem ntau tsis tuaj yeem raug kho thaum lub sijhawm tom qab ntau lawm lossis cov digital editing.
