Dab tsi yog xim rendering Performance index (CRI) thiab vim li cas nws tseem ceeb kom coj teeb pom kev zoo?
Tsis tuaj yeem qhia qhov sib txawv ntawm cov thom khwm dub thiab ua kas fes hauv koj lub txee dai khaub ncaws hauv qab koj lub teeb fluorescent? Yuav yog tias qhov teeb pom kev tam sim no muaj qhov qis heev CRI. Xim Rendering Performance index (CRI) yog qhov kev ntsuas ntawm li cas cov xim uas muaj xim zoo nkauj hauv qab lub teeb ci dawb thaum piv nrog tshav ntuj. Qhov ntsuas yog ntsuas los ntawm 0-100, nrog rau 100 qhia tau tias cov xim ntawm cov khoom nyob rau hauv lub teeb pom kev zoo ib yam li lawv yuav nyob rau hauv lub hnub ci. Cris nyob rau hauv 80 feem ntau suav hais tias 'tsis zoo' thaum nyob deb tshaj 90 tau txiav txim siab 'yog' Great '.
Loj Cri Led teeb pom kev zoo nkauj, muaj suab paj nruag thoob plaws cov xim muaj xim. Txawm li cas los xij, Cri tsuas yog ib qho ntsuas rau lub teeb zoo. Txhawm rau nkag siab txog lub peev xwm lub peev xwm los ua cov xim uas koj xav tau, muaj kev sim ntxaum uas peb ua thiab peb cov kws tshawb nrhiav teeb tsa pom zoo xav. Peb yuav nthuav dav qhov ntawd ntxiv nyob ntawm no.
Uas cri ranges siv
Thaum kev yuav khoom thiab txhim kho cov teeb liab dawb, peb pom zoo cov CRI ntawm dhau 90 tab sis kuj tseem hais hauv qee cov haujlwm, tsawg kawg ntawm 85 tuaj yeem siv tau. Hauv qab no yog cov lus qhia luv luv ntawm CRI ranges:
CRI 95 - 100 → Zoo phim xim rendering. Cov xim tshwm raws li lawv yuav tsum, hloov maj mam cov suab paj nruag tau zoo nkauj, kos duab tawv nqaij zoo nkauj, cov xim tawv los ua ciaj sia, nraub qaum pom lawv cov xim tseeb.
Siv dav hauv Hollywood ntau lawm teeb, High-end retetes cov khw muag khoom, thiab hauv cov ntawv thov hauv chaw nyob uas cov xim muaj xim yuav tsum tau ci ci.
CRI 90 - 95 → Zoo xim rendering! Yuav luag txhua xim 'Pop' thiab yog qhov sib txawv yooj yim. Hais tias lub teeb pom kev zoo pib ntawm ib qho CRI ntawm 90. Cov qhua pib ua tiav cov txee, pleev xim, thiab cov ntsiab lus ntawm koj chav ua noj, tab sis me ntsis ua lawv lub teeb pom kev zoo tshaj plaws rau nws saib zoo li cas.
Cri 80 - 90 →Cov xim zoo rendering, uas feem ntau cov xim yog rov qab zoo. Txais tau rau feem ntau ua lag luam siv. Koj yuav tsis pom cov khoom uas muaj txhij raws li koj xav tau.
CRI hauv qab no 80 →Teeb pom kev zoo nrog CRI hauv qab no 80 yuav suav tias yog muaj cov xim tsis zoo xim. Nyob rau hauv lub teeb no, cov khoom thiab xim yuav saib tau kev cia siab, cov drab, thiab lub sijhawm tsis pom zoo (zoo li lub cev sib txawv ntawm cov plaub hau dub thiab kob). Nws yuav nyuaj rau kev paub qhov txawv ntawm cov xim zoo sib xws.
Cov xim zoo rendering yog qhov tseem ceeb rau kev thaij duab, khw muag khoom pom kev, kos duab pom kev zoo, kos duab qhia, thiab chav ua yeeb yam tsuas yog rau npe ob peb. Ntawm no, ib qho peev txheej ntawm lub teeb nrog lub cri saum 90 yuav xyuas kom cov xim zoo li lawv yuav tsum ua li cas thiab tshwm ntsej muag thiab ci dua. Siab Cri teeb pom kev zoo sib xws nyob hauv cov ntawv thov cov chaw nyob, raws li nws tuaj yeem hloov cov ntsiab lus tsim qauv thiab tsim kom xis nyob, ntuj tag nrho. Ua tiav yuav muaj qhov tob ntxiv thiab luster.
Kuaj rau cri
Kev kuaj rau CRI yuav tsum tau tshwj xeeb machinery tsim tshwj xeeb rau lub hom phiaj no. Thaum lub sijhawm kuaj sim no, lub teeb spectrum ntawm lub teeb yog kev tshuaj xyuas rau yim cov xim sib txawv (lossis "R qhov tseem ceeb"), tsis muaj R1 los ntawm R8.
Muaj 15 ntsuas uas tuaj yeem pom hauv qab no, tab sis cov teeb pom kev zoo li cov xim ntawm " Koj tuaj yeem pom los ntawm cov qauv hauv qab no, txawm tias daim duab thib ob muaj cov CRI ntawm 81, nws yog qhov txaus ntshai ntawm rendering cov xim liab (R9).
Teeb cov tuam ntxhab tam sim no sau cov kev ntsuas nrog lawv cov khoom lag luam, thiab tsoomfwv qib pib xws li California Lub Npe, siab Cri teeb pom kev zoo.
Txawm hais tias CRI tsis yog qhov chaw sawv-ib leeg rau ntsuas teeb pom kev zoo; Cov koom haum tshawb nrhiav teeb pom kev zoo tseem pom zoo muab cov kev siv sib txuas ntawm TM-30-20 GAMUT DAGORS INCRESS INCTRESS CEEB TOOM INCALIT.
Cri tau siv los ua qhov ntsuas txij li xyoo 1937. Qee tus ntseeg tias CRI ntsuas yog qhov tsis zoo rau tam sim no ua kom zoo ntawm kev ua tau los ntawm lub teeb ci. Cov kev ntsuas ntxiv no yog xim zoo nkauj (CQS), IES TM-30-20 suav nrog Gamut Index, Fould Index, Xim Vector.
CRI - Xim Rendering Performance index -Yuav ua li cas ze rau lub teeb pom kev tuaj yeem muab cov xim xim zoo li lub hnub, siv 8 xim kuaj.
Fidelic Index (TM-30) -Yuav ua li cas ze rau lub teeb pom kev tuaj yeem muab cov xim zoo li lub hnub, siv 99 xim kuaj.
Gamut Index (TM-30) - Yuav ua li cas cov xim noo los yog desaturated yog (aka yuav ua li cas khaus cov xim muaj).
Xim Vector Graphic (TM-30) - Cov xim twg yog cov xim khov kho / desaturated thiab seb puas muaj ib tug Hawje hloov hauv ib qho ntawm 16 xim bins.
CQS -Xim zoo nplai - lwm txoj hauv kev rau cov xim tsis muaj xim. Muaj 15 cov xim muaj kuab heev uas tau siv los sib piv cov chraratic kev ntxub ntxaug, tib neeg nyiam, thiab xim rendering.
Uas LED Sawb Lub Teeb yog qhov zoo tshaj rau koj qhov project?
Peb tau tsim tag nrho peb cov tawv dawb kom muaj cov cri siab tshaj 90 nrog tsuas yog siv ib qho kev zam tshwj xeeb (rau kev lag luam siv), uas txhais tau tias lawv tau ua haujlwm zoo tshaj cov xim ntawm cov khoom thiab qhov chaw koj tau istuminating.
Nyob rau sab saum toj kawg ntawm tej yam, peb tau tsim ib qho ntawm qhov siab tshaj plaws CRI coj cov qauv kev teeb tsa lossis rau kev yees duab, TV, ua haujlwm textile. Lub Ultrabright ™ Render series muaj qhov tseem ceeb r zoo tshaj plaws, suav nrog tus qhab nia siab R9. Koj tuaj yeem nrhiav tau ntawm no tag nrho ntawm peb cov ntawv tshaj xo photometric uas koj tuaj yeem pom cov nqi Cri rau tag nrho peb cov kab.
Peb Led Sawb Teeb thiab lub teeb tuav los rau ntau yam ntawm lub ci ci, xim kub, thiab ntev. Dab tsi lawv muaj nyob rau hauv ib qho yog qhov siab heev cri (thiab CQS, TLCI, TM-30-20). Nyob rau hauv txhua nplooj ntawv khoom, koj yuav pom cov ntawv tshaj xo photometric uas qhia tag nrho cov no nyeem.
Kev sib piv ntawm cov siab cri coj sawb teeb
Hauv qab no koj yuav pom kev sib piv ntawm lub ci ci (lumens rau ib txhais taw) ntawm txhua cov khoom. Peb ib txwm muaj los pab koj hauv kev xaiv cov khoom lag luam zoo thiab.
