Vim li cas CRI 80 Lub Teeb Ua Rau Kua Liab Liab Pom Grey? - Qhov R9 Qhov Tseeb Koj Yuav Tsum Paub
Koj puas tau yuav cov nqaij nyug liab tshiab ntawm lub khw, tsuas yog nqa mus tsev thiab pom nws zoo li grey thiab npub hauv qab koj lub teeb chav ua noj? Los yog sim hnav khaub ncaws liab ci hauv lub khw uas zoo li zoo nkauj, tab sis tom qab nqa nws los tsev nws tshwm sim ploj mus? Qhov no tsis yog koj lub tswv yim - nws yog koj lub teebxim rendering index- los yog ntau dua, aqis R9 tus nqi.
1. CRI yog dab tsi thiab nws qhov teeb meem loj?
Xim Rendering Index (CRI)ntsuas qhov tseeb npaum li cas lub teeb pom kev pom tseeb xim ntawm cov khoom, qhia raws li tus nqi Ra nrog qhov siab tshaj plaws ntawm 100 (hnub ntuj). Cov txheej txheem kev lag luam suav CRI los ntawm qhov nruab nrabyim xim qauv (R1 txog R8): lub teeb liab, daj-ntsuab, daj-ntsuab, lub teeb ntsuab, xiav-ntsuab, lub teeb xiav, lub teeb violet, thiab ntshav-liab.
Lub txim tuag ntawm CRI: tsis muaj ib qho ntawm yim tus qauv noliab saturated! Qhov no txhais tau hais tias lub teeb muaj peev xwm ua tau zoo kawg nkaus rau yim xim tab sis ua tsis zoo rau xim liab (zoo li xiav xiav thiab ntsuab tob). Thiab liab yog xim tseem ceeb tshaj plaws rau nqaij, txiv hmab txiv ntoo, tawv nqaij tones, thiab tshuaj pleev ib ce.
2. R9: Qhov taw qhia Overlooked Saturated Liab
Nyob rau hauv tag nrho cov xim rendering Performance index system, ntxiv rau R1-R8, muaj cov qauv txuas ntxiv R9 txog R15.R9 sawv cev rau saturated liab. Daim ntawv teev cov khoom lag luam LED tiav yuav tsum sau tus nqi R9.
| Xim Rendering Index | Kuaj Xim Xim | Hom Daim Ntawv Thov Qhov Tseem Ceeb |
|---|---|---|
| CRI (Ra) | Qhov nruab nrab ntawm R1-R8 | Kev ntsuam xyuas dav dav ntawm cov xim rendering |
| R9 | Saturated liab | Nqaij, txiv hmab txiv ntoo, tawv tones, mem pleev di ncauj, liab cib, ntoo liab |
| R10 | Saturated daj | Txiv tsawb, pob kws, xim |
| R11 | Saturated ntsuab | Zaub, nyom |
| R12 | Saturated xiav | Jeans, marine ntxhais |
| R13 | Caucasian tawv nqaij | Photography, pleev, kho mob |
| R15 | Asian skin tone | Asian tawv xim rendering |
Kev lag luam siv tus nqi rau R9:
- R9 <0: Liab tshwm grey, npub, los yog distorted (feem ntau nyob rau hauv pheej yig LEDs)
- R9 = 10–30: NW nyuam qhuav txais tau, tseem tsis zoo tagnrho
- R9 = 50–70: Zoo liab rendering (zoo coj mus muag teeb pom kev zoo)
- R9 Ntau dua lossis sib npaug rau 80: Zoo heev liab rendering (tsev cia puav pheej, high-end khw muag khoom, chav khiav hauj lwm)
3. Vim li cas R9 thiaj li tseem ceeb? - Peb Qhov Tseeb-Lub Ntiaj Teb Scenarios
3.1 Cov khw muag khoom noj tshiab
Lub steak tshiab nyob rau hauv lub teeb nrog R9=0 zoo li nws tau zaum tawm tau peb hnub. Cov kev tshawb fawb pom tau hais tias teeb pom kev zoo nrog R9> 50 tuaj yeem ua kom cov nqaij muag hloov pauv los ntawm 15% -20%.
3.2 Khaub ncaws thiab tshuaj pleev ib ce
Cov mem pleev di ncauj liab, tiab liab, lub tsheb ua kis las liab - cov khoom muaj txiaj ntsig zoo xav tau siab R9 los qhia lawv qhov tseeb vividness. Tsawg R9 ua rau liab zoo li xim av lossis npub.
3.3 Kev ntsuam xyuas kho mob thiab tawv nqaij
Cov kws kho mob yuav tsum txiav txim kom raug rau cov neeg mob cov tawv nqaij xim, qhov txhab congestion, thiab cov tsos ntawm pob liab liab. R9 ua ke nrog R13 (Caucasian daim tawv nqaij) / R15 (Asian daim tawv nqaij) ncaj qha cuam tshuam qhov tseeb ntawm kev kuaj mob.
4. Hom CRI thiab R9 sib xyaw ua ke - Yuav Ua Li Cas Nyeem Daim Ntawv Teev Npe
| Qib khoom | CRI (Ra) | R9 nqi | Tej kev siv |
|---|---|---|---|
| Kev lag luam qis kawg | 70–80 | <0 (even negative) | warehouses, corridors, chaw nres tsheb |
| Kev lag luam dav dav | 80–85 | 5–20 | Chaw ua haujlwm, tsev kawm ntawv, factories |
| Premium coj mus muag | 85–90 | 30–60 | Cov khw muag khoom, tsev so, tsev noj mov |
| High-end kev tshaj lij | 90–95 | 70–85 | Cov khw muag khoom noj tshiab, cov chaw ua yeeb yaj kiab, duab studios |
| Sab saum toj kho mob / tsev cia puav pheej | 95–98 | Ntau dua lossis sib npaug li 90 | Cov chav ua haujlwm, tsev cia puav pheej kos duab, cov txee tshuaj pleev ib ce |
Key muab: CRI 90 uatsis yogtxiav txhais tau tias siab R9. Qee lub tuam txhab txhawb nqa CRI los ntawm kev ua kom zoo R1-R8 thaum ua kom R9 qis heev. Koj yuav tsumnug tus nqi R9 cais.
5. Yuav Ua Li Cas Ntsuas thiab Tshawb Xyuas R9
- Nug rau lub spectral fais fab faib graph- Tus neeg muag khoom raug cai yuav tsum muab qhov sib txheeb spectral fais fab faib ntawm lub luminaire. Yog tias koj pom qhov sib txawv ntawm cov kab liab (620-700nm), R9 yuav zoo.
- Nug cov ntaub ntawv xeem thib peb- Thov daim ntawv tshaj tawm kev xeem ua raws li IES TM-30 lossis CIE 13.3, uas yuav qhia meej tag nrho cov nqi R1-R15.
- Kev sim yooj yim ntawm qhov chaw- Ci lub teeb rau ntawm cov khoom liab dawb (xws li, daim npav liab lossis cov kua liab) thiab muab piv rau nruab hnub nrig. Yog tias liab tshwm grey, xim av, lossis tsaus dua, R9 yog qis.
6. TM-30: Lub Txheej Txheem Tshaj Lij Tshaj Li CRI
Nyob rau hauv xyoo tas los no, kev lag luam teeb pom kev zoo tau txais kev pom zooTXM-30tus qauv, uas siv 99 xim qauv (nrog rau ntau cov xim saturated) thiab ntsuas nrog ob qhov ntsuas:
- Rf (kev ncaj ncees)- zoo ib yam li CRI tab sis muaj ntau dua
- Rg (Gamut Index)- ntsuas seb cov xim puas dhau los ua kom zoo dua lossis kaw
Txawm li cas los xij, rau feem ntau cov xwm txheej kev yuav khoom,CRI + R9tseem yog qhov ua tau zoo tshaj plaws thiab feem ntau siv tshuaj ntsuam xyuas cov cuab yeej.
CRI qhia koj qhov "nruab nrab" xim rendering theem ntawm lub teeb, tab sisR9 qhia koj tias nws ua tau zoo npaum li cas cov xim tseem ceeb tshaj plaws - liab. Lwm zaus koj xaiv LED luminaires - tshwj xeeb tshaj yog rau cov khoom noj tshiab, khw muag khoom, khaub ncaws, kho mob, lossis kev siv hauv tsev siab - tsis txhob saib seb CRI yog 80 lossis 90. Nco ntsoov nug:Tus nqi R9 yog dab tsi?Lub teeb nrog CRI 90 tab sis R9=5 yog qhov phem dua ntawm kev qhia cov kua liab dua li lub teeb nrog CRI 85 tab sis R9=60.
Yog tias koj muaj kev xav tau rau kev yuav khoom ntau lossis kev kho teeb pom kev zoo,xav tias dawb hu rau peb rau cov ncauj lus kom ntxaws.
