Thaum lub rooj sib tham saib xyuas cov khoom, peb feem ntau hnov: "Lub COB LED no muaj CRI Ra 95 thiab R9 85 - pom zoo rau kev tsim khoom." Nres! Qhov kev txiav txim siab no tuaj yeem ua rau koj lub teeb lub koob npe nrov hauv kev ua lag luam.
Rau xinesmas, yees duab, thiab siab -kawg nyob streaming teeb, tsom rau CRI (Ra) nkaus xwb zoo li txiav txim lub tsheb kis las los ntawm kev suav nws lub log. Nws nco qhov kev ua tau zoo tiag tiag uas tseem ceeb. Vim li cas qee lub teeb ua rau cov tawv nqaij zoo nkauj thiab zoo nkauj thaum lwm tus zoo li daj ntseg lossis ntsuab? Vim li cas ntau lub teeb ntawm lub teeb tsim kom pom cov xim hloov? Vim li cas cov neeg pleev kob tawm tsam hauv kev tshaj tawm - ntau lawm?
Cov lus teb nyob rau hauv feem ntau-tsis pom kev: R9, TLCI, SSI, Duv, SDCM, Rf, thiab Rg. Phau ntawv qhia no piav qhia txog cov xwm txheej no cuam tshuam li cas tiag -cov txiaj ntsig hauv ntiaj teb thiab vim li cas COB (Chip on Board) LED thev naus laus zis feem ntau yog qhov kev xaiv zoo tshaj plaws rau kev ua tiav lawv.
1. CRI (Ra) & R9: Tus yuam sij rau cov tawv nqaij kom raug
CRI (Ra) nruab nrab qhov teeb pom kev zoo ua rau 8 tus qauv qis - xim saturation. Nws tsis suav nrog cov liab muaj zog.
Ntau qhov chaw ncav cuag Ra 95+, tab sis lawv cov R9 (saturated liab) nyob qis. Qhov tshwm sim? Cov tawv nqaij tones saib tsis zoo, thiab daim di ncauj thiab cov ntaub liab zoo li npub.
Cov qauv pom zoo:
• Nkag mus-level: Ra > 90, R9 > 50 (tsuas yog siv yooj yim)
• Kev yees duab tshaj lij: Ra> 95, R9> 80 (yam tsawg kawg rau cov tawv nqaij tones)
• Cinema/Film-grade: Ra > 96, R9 > 90 (natural, flattering results with me me post-corection)
Tswv yim:Nco ntsoov nug tus nqi R9. Siab CRI tsis muaj zog R9 tseem tuaj yeem ua rau poob siab hauv portrait thiab tib neeg- tsom rau kev ua haujlwm.
2. TLCI & SSI: Ua kom zoo rau cov koob yees duab
CRI ntsuas rau tib neeg lub qhov muag, tab sis lub koob yees duab sensors teb txawv.
Lub teeb uas zoo nkaus li zoo rau lub qhov muag yuav hloov ntsuab lossis magenta ntawm lub koob yees duab, ua rau tsis sib haum nyob rau ntau lub koob yees duab kaum.
Cov qauv pom zoo:
• Tshaj tawm / Zaj duab xis theem: TLCI> 90, SSI (D5600K)> 80
• High-kawg xinesmas: SSI > 85 (ze ze rau lub hnub ci ntuj, huv si ncaj- tawm- ntawm - lub koob yees duab footage)
Tswv yim:Rau cov neeg siv tua nrog Sony, ARRI, lossis RED koob yees duab, ua ntej TLCI thiab SSI tshaj CRI ib leeg.
3. Duv (Δuv): Avoiding Green or Magenta Tint
Duv ntsuas deb npaum li cas lub teeb xim taw tes sib txawv ntawm qhov zoo tshaj plaws blackbody nkhaus.
Pom zoo Duv tsim ib qho ntsuab cam khwb cia (feem ntau pom thiab nyuaj kho). Negative Duv leans liab / ntshav.
Cov qauv pom zoo:
• Teeb pom kev zoo: |Duv| <0.006 (tau txais)
• Kev xinesmas & yees duab: |Duv| <0.003 (huv, nruab nrab dawb)
• Qib hwm: |Duv| <0.002 (zoo purity)
Tswv yim:Txawm tias CCT yog qhov tseeb (piv txwv li, 5600K), siab Duv tuaj yeem ntxiv cov xim tsis xav tau uas cov koob yees duab khaws tau yooj yim.
4. SDCM: Xim Consistency hla ntau lub teeb
SDCM (MacAdam ellipses) qhia tau hais tias teeb pom kev zoo li cas los ntawm tib pawg sib tw hauv cov xim thiab xim.
Cov qauv pom zoo:
• Kev siv tshaj lij: SDCM Tsawg dua lossis sib npaug li 4
• High- teeb tsa xinesmas kawg: SDCM Tsawg dua lossis sib npaug li 2–3 (ntau lub teeb ua haujlwm ua ke yam tsis pom kev hloov pauv)
Tswv yim:Muab SDCM Tsawg dua lossis sib npaug rau 3 nrog Duv < 0.003 rau kev txhim khu kev ntseeg ntau - teeb arrays hauv studios.
5. TM-30 (Rf & Rg): Tiag tiag vs. Vibrant Xim
TM-30 yog ib tug niaj hnub system. Rf ntsuas kev ncaj ncees (qhov tseeb xim zoo li cas), thaum Rg ntsuas saturation (vim li cas lawv tshwm).
Daim ntawv thov -raws li cov hom phiaj:
• Portraits/Documentary: Rf > 92, Rg ≈ 98–102 (zoo saib)
• E-commerce/Fashion/Food: Rf> 90, Rg ≈ 102–105 (kev thov kom rov hais dua me ntsis)
• Tsev khaws puav pheej/Art: Rf> 95, Rg nruj tswj ze li ntawm 100 (txoj kev loj hlob)
Qhov kev sib xyaw ua ke no pab tsim cov teeb tshwj xeeb rau kev lag luam sib txawv.
6. CQS & GAI: Kev kuaj xyuas zoo ntxiv
• CQS: nruj dua CRI rau cov xim saturated. Lub hom phiaj rau CQS> 90 hauv cov teeb pom kev zoo.
• GAI: Pab tau rau theem (siab dua rau kev cuam tshuam) lossis xov xwm (ze li 100 rau qhov nruab nrab).
Vim li cas COB LED Outperforms Traditional SMD rau Professional Teeb?
SMD siv ntau lub LEDs me me, uas tuaj yeem tsim cov hotspots, ntau qhov ntxoov ntxoo, thiab kev sib txawv ntawm pawg.
COB mounts chips ncaj qha rau ntawm ib lub rooj tsavxwm rau ib leeg, teeb pom kev zoo.
Cov txiaj ntsig tseem ceeb ntawm COB:
• Smoother, softer tso zis nrog tsawg dua hnyav ntxoov ntxoo thiab huv dua catchlights.
• Yuav luag tsis muaj ntau yam dab nyob rau ntawm qhov chaw muaj kev cuam tshuam (iav iav, cov ntxaij vab tshaus, cov khoom).
• Cov xim zoo sib xws (yooj yim dua kom ua tiav Duv qis thiab nruj SDCM).
• Tsawg thermal tsis kam → xim ruaj khov thiab ua haujlwm tsawg dua ntawm cov tua ntev.
• Yooj yim optics rau cov kab teeb uas tsis muaj lub nplhaib daj lossis lub teeb tsis pom kev.
Rau kev thov xinesmas thiab kev yees duab daim ntawv thov, COB feem ntau yog cov kev daws teeb meem.
WELCOB: Siab -Kev ua tau zoo COB LED rau kev thov kev thov
Ntawm WELCOB, peb tshwj xeeb hauv kev hwm COB LED cov kev daws teeb meem tsim los rau kev tshaj lij. Peb cov xinesmas- qib COB series tsom rau qhov tsis muaj qhov tseem ceeb tshaj:
• Muaj zog liab rendering: R9 > 90
• Lub koob yees duab-kev ua tau zoo: TLCI > 95, SSI > 85
• Tight xim tswj: |Duv| <0.003 (tus qauv <0.002)
• Cov khoom zoo sib xws: SDCM Tsawg dua lossis sib npaug li 3
Peb kuj tseem muab kev kho kom haum rau cov kev xav tau tshwj xeeb - teeb pom kev zoo nkauj rau kev tshaj tawm hauv xov xwm, raug tsim tawm rau cov tsev cia puav pheej, lossis tag nrho - spectrum daylight simulation rau zaj duab xis. Kev them nyiaj yug suav nrog tag nrho cov ntaub ntawv IES, cov ntaub ntawv spectral, thiab thib peb -cov ntaub ntawv xeem cov tog neeg los pab koj ua tiav sai. Tsis txhob cia qhov nruab nrab lub teeb tso cai txwv koj cov khoom siv. Hauv cov duab niaj hnub no-kev ua lag luam, txoj cai COB LED txiav txim siab qhov zoo thiab kev ntseeg siab ntawm koj cov khoom teeb pom kev zoo.
