Npuag Ribbon Gift Box Xaiv cov xim teeb lub thawv

 

Nws yog ib qho teeb meem nyuaj heev los nrhiav qhov chaw soj ntsuam uas tuaj yeem ua ncaj ncees sawv cev rau cov xim ntawm cov ntawv sau qub. Daim ntawv luam ntawm cov ntawv luam tawm, nyob rau hauv dab tsi ib puag ncig los xyuas, kev ntsuam xyuas yog tus qauv txaus, yuav tsis muaj xim txawv?

 

Ntawm chav kawm, nyob rau hauv tus txheej txheem ntawm ntau lawm, qhov zoo tshaj plaws tej yam kev mob rau proofreading tus thawj thiab luam tawm, yog sib npaug rau qhov kawg ntawm kev soj ntsuam ib puag ncig. Tab sis tag nrho peb cov ntawv luam tawm, tsis yog rau ib tus neeg siv khoom xwb, tej zaum ntau txhiab, tej zaum txawm ntau txhiab tus neeg tuaj yeem nkag mus rau peb cov ntawv luam tawm, yog li peb puas yuav tsum tsim ntau txhiab qhov kev soj ntsuam ib puag ncig? Peb txhua tus paub tias qhov no ua tsis tau. Vim tias lub teeb ci yuav hloov nrog lub sijhawm thiab ib puag ncig, cov khoom muaj xim sib txawv nyob rau hauv qhov sib txawv ntawm cov teeb pom kev zoo, yog tias koj xav tsim cov ntawv luam tawm tsim nyog rau kev soj ntsuam raws li qhov sib txawv ntawm lub teeb, cov nqi thiab cov neeg ua haujlwm yuav ua rau cov khoom pov tseg tsis tsim nyog. Yog li ntawd, peb yuav tsum tsim kom muaj lub hom phiaj thiab tus qauv ib puag ncig kom ntseeg tau tias kev soj ntsuam zoo ib yam tuaj yeem siv thoob plaws hauv kev tsim khoom.

 

5000K tsis nkag siab

Qee cov tuam txhab yuav hais tias lawv siv cov xim sib txuam cov ntawv sau lub teeb (tau 5000K xim kub lub teeb qhov chaw, vim li cas rau cov neeg siv khoom kuj tseem muaj 5000K lub teeb ci ib puag ncig, cov ntawv sau xim tseem tsis raug?) Cia thawj txoj cai tawm qhov teeb meem ntawm kev luam ntawv zoo thiab ces tawg kab lus no. Cia peb pib nrog cov lus nug ntawm lub teeb. Qhov tseeb, 5000K tsuas yog piav qhia cov xim kub ntawm lub teeb ci, tsis sawv cev rau tag nrho cov teeb pom kev zoo. Hais lus kom raug, lub teeb ci tawm los ntawm D50 tus qauv teeb pom kev zoo lub cev yog qhov pom zoo lub teeb pom kev zoo rau cov txheej txheem luam ntawv. Thov nco ntsoov kom paub meej tias qhov teeb pom kev zoo no ntxiv rau qhov tsim nyog xim kub, tab sis kuj muaj xim txaus.

 

Cia peb pib nrog 5000K xim kub. Peb sov lub cev dub txheem uas tuaj yeem nqus tau thiab tawg lub zog. Raws li qhov kub thiab txias, cov xim ntawm nws lub teeb hloov pauv. Piv txwv li, thaum xim kub ntawm lub hnub nruab nrab yog 6500K, xim ntawm lub teeb ci ntawm lub cev dub yog tib yam li lub hnub nruab nrab. 5000K xim kub txhais tau hais tias thaum lub cev dub yog rhuab mus rau 5000K, nws lub teeb xim hloov mus rau dawb, thiab nws spectral zog faib yog ntsuas. Lub zog ntawm cov qhab nyob rau hauv xiav, ntsuab thiab liab cheeb tsam qhia tau hais tias ib qho isoenergy lub xeev, uas yog, lub teeb dawb zoo tshaj plaws nrog cov xim qis tshaj plaws. Yog li ntawd, cov txheej txheem luam ntawv xaiv lub teeb ci nrog 5000K xim kub thiab tsis hais txog cov xim twg zoo dua li lwm yam.

 

Tsis tas li ntawd, muaj teeb meem ntawm cov xim rendering. Xim rendering yog hais txog qhov sib xws ntawm cov xim ntawm ib yam khoom nyob rau hauv lub hnub ci thiab khoom siv lub teeb ci. Cov xim ntawm cov khoom nthuav tawm nyob rau hauv tshav ntuj yog qhov tseeb tshaj plaws, vim hais tias lub zog spectral faib nyob rau hauv lub hnub ci yog qhov dav tshaj plaws, thiab nws tuaj yeem nthuav qhia tag nrho cov xim ntawm cov khoom (lub sijhawm no, xim rendering Performance index ntawm lub hnub ci yog qhov siab tshaj plaws. 100 Ib). Txawm li cas los xij, lub zog spectral faib ntawm cov khoom siv teeb pom kev zoo tseem sib txawv ntawm cov hnub ci nyob ntawm cov khoom sib txawv. Txawm li cas los xij, cov xim ntawm cov khoom tseem txawv ntawm qhov pom ntawm lub hnub ci txawm tias lub teeb ci dawb muaj xim kub ntawm 5000K. Feem ntau ntawm cov teeb meem yog tias cov khoom siv teeb pom kev zoo feem ntau tsis muaj cov khoom siv monochromatic, thiab cov xim rendering Performance index tsawg dua 100Ra. Qib ntawm cov xim rendering Performance index sawv cev rau qhov distortion ntawm cov khoom.

 

Tab sis muaj qhov siab xim rendering Performance index tsis txhais hais tias tsis muaj xim tsis ncaj ncees. Nco ntsoov tias cov xim kub ntawm lub teeb ci thiab xim rendering yuav tsum koom tes nrog ib leeg. Xim kub yog qhov qhia txog xim ntawm lub teeb ci, thiab xim rendering yog qhov qhia txog qhov zoo ntawm lub teeb. CIE D50 tus qauv teeb pom kev zoo lub cev yog txhawm rau txheeb xyuas qhov zoo ntawm lub teeb ci xim kom ua qauv.

 

Standard teeb pom kev zoo lub cev thiab standard lub teeb qhov chaw

CIE International Association for Lighting Standards tau pom tias cov teeb pom kev sib txawv muaj qhov sib txawv ntawm cov xim xim ntawm cov khoom, yog li nws txhais cov qauv teeb pom kev zoo hauv qab no, thiab qhia txog nws lub zog spectral.

 

Txawm li cas los xij, cov qauv illuminators saum toj no tuaj yeem ua tiav los ntawm kev sib txuas ntawm cov teeb pom kev sib txawv (simulating spectral zog faib), tab sis cov khoom sib txawv muaj kev ruaj ntseg sib txawv, yog li CIE pom zoo rau cov txheej txheem illuminators (cov khoom siv teeb pom kev zoo) los ua kom tiav cov txheej txheem saum toj no illuminators.

 

ISO 3664 Kev soj ntsuam tus qauv

Tham txog ntau qhov chaw teeb pom kev zoo thiab cov ntaub ntawv teeb pom kev zoo, yog li dab tsi yog qhov zoo tshaj plaws xim sib piv ib puag ncig? Xyoo 1975, lub koom haum ISO International Standards Certification Institute tau luam tawm ISO 3664 Teeb pom kev zoo rau saib xim Lenses thiab luam tawm (tus tshiab version yog ISO 3664: 2000), uas hais txog cov xwm txheej ntawm kev saib hauv kev luam ntawv thiab luam tawm, raws li qhia hauv nram qab no plaub lub ntsiab lus:

 

1. Spectral zog faib ntawm qhov chaw teeb pom kev zoo

2. Luminous degree thiab qhov sib npaug ntawm lub teeb ci

3. Saib xyuas ib puag ncig ib puag ncig --

i) Saib xyuas ib puag ncig --

ii) Teeb pom kev zoo

4. Kev ruaj ntseg ntawm qhov chaw teeb pom kev zoo

Qhov tseeb, ISO 3664: 2000 teeb pom kev zoo qhov yuav tsum tau nruj dua, nws yuav siv sij hawm mus rau hauv tus account tam sim no pib ntawm tshiab xim imaging technology thiab proofing system, tab sis kuj rau cov khoom nyob rau hauv txawv lub teeb qhov chaw, tsim heterochromatic spectrum los ua qhov teeb meem ntawm kev cai. , thiab rau cov nyhuv ntawm UV kua roj vanish ntawm cov ntaub ntawv luam tawm, thiab kev txhim kho ntawm tus qauv tshiab no. [tom ntej]

 

A. Illuminance

Lwm qhov tseem ceeb yog tias nws pom zoo ob lub teeb pom kev zoo rau kev siv hauv cov xwm txheej hauv qab no:

1. High illumination 2000I± 500lux - siv rau kev ntsuam xyuas thiab kev sib piv ntawm cov duab, nruj kev ntsuam xyuas ntawm luam ntawv.

2. Tsawg illuminance 500I± 25lux -- siv los daws cov ntsiab lus tsaus nti ntawm daim duab nyob rau hauv qhov kev soj ntsuam zaum kawg zoo sib xws.

(Nyob rau hauv kuv lub tswv yim, siab illuminance yog haum rau siv nyob rau hauv txhua txhua luam ntawv txheej txheem ntau lawm, thiab tsawg illuminance yuav raug xaiv rau ib tug sib piv ntawm cov duab cov ntsiab lus.)

 

B. Saib xyuas ib puag ncig

Kev soj ntsuam ib puag ncig tej zaum yuav yog qhov txuas tsis quav ntsej los ntawm txhua qhov kev lag luam luam ntawv. Kuv ntseeg tias koj yuav tsum tau pom tias qhov chaw soj ntsuam nyob ib puag ncig lub rooj cob qhia muaj ntau yam khoom, cov ntawv tshaj tawm, tus cwj mem, hnab luam yeeb, xov tooj ntawm tes thiab lwm yam. Qee qhov chaw ntawm cov ntawv sau xim tseem nyob hauv ib cheeb tsam tom ntej ntawm lub qhov rais sill, thiab qee qhov muaj plua plav ntau dua.

 

1. Txo kev cuam tshuam los ntawm koj ib puag ncig.

2. Tom qab nkag mus rau qhov chaw soj ntsuam, yuav tsum tsis txhob pib txiav txim rau kev luam ntawv tam sim ntawd, kom cov neeg ua haujlwm muaj sijhawm los hloov mus rau ib puag ncig.

3. Tsis muaj lub teeb ntxiv yuav tsum nkag mus rau qhov chaw saib (xws li kev xav).

4. Yuav tsum tsis muaj cov xim muaj zog nyob ib puag ncig (cov neeg ua haujlwm 'tag nrho).

5. Lub periphery ntawm qhov kev soj ntsuam yuav tsum yog nruab nrab grey thiab tsaus xim blocks nrog reflectance tsawg dua 60 feem pua.

 

Qhov tseeb, cov saum toj no yog cov chaw luam ntawv yuav tsum tau them sai sai rau qhov teeb meem, cov xwm txheej no tsuas yog lub teeb liab, tuaj yeem siv tau, tsis yog tsuas yog txhim kho ib puag ncig, tab sis kuj tseem txhim kho qhov zoo ntawm cov khoom, txhim kho cov duab hauv lub Hoobkas. .

 

ISO 3664: 2000 hais tias tus qauv kev soj ntsuam ib puag ncig ntawm ntau txhiab lo lus, cov saum toj no tsuas yog tsawg, yog tias cov tuam txhab npaj siab los txhim kho qhov kev soj ntsuam ib puag ncig, koj tuaj yeem mus saib ISO lub vev xaib www.iso.org, rub tawm cov ntaub ntawv cuam tshuam ntawm tus qauv rau siv.

 

Yuav xaiv cov khoom siv teeb pom kev zoo li cas

Txoj kev yooj yim tshaj plaws los ua qhov no yog mus yuav lub thawv teeb uas ua raws li ISO cov qauv. Tau kawg, koj tau txais yam koj them rau. Cov me me feem ntau raug nqi ntau tshaj kaum txhiab yuan, thiab cov loj yuav raug nqi ntau tshaj peb caug txhiab yuan. Yuav ua li cas cov tshuab luam ntawv tuaj yeem nqis peev? Txawm li cas los xij, hom kev ntsuas xim lub teeb lub thawv no, ntxiv rau kom ua tau raws li ISO cov cai, muaj ntau yam teeb pom kev zoo xaiv los ntawm, xws li D65, D50, UV, TL84, A, thiab lwm yam, haum rau cov kev xav tau sib txawv. Cov neeg tsim khoom txaus siab tuaj yeem tuaj xyuas Lub Chaw Tshawb Xyuas Cov Khoom Siv Luam Ntawv thiab Tshuaj Ntsuam. Nws yog vim qhov peev nyiaj ntawm kev sib raug zoo, yog li ntau tus neeg tsim khoom xav txog kev yuav rov qab, thiab tom qab ntawd nrhiav ib tus neeg los ua. Peb kuj tuaj yeem thov qee cov ntaub ntawv tsim nyog kom phim lub thawv teeb hauv tsev.

 

1. Lub teeb raj -- muaj ntau lub npe ntawm lub teeb raj ntawm lub khw uas qhia tias muaj 5000K tag nrho (hmoov tsis tau CIE tsis tau teev cov qauv teeb pom kev zoo ntawm D50 tus qauv lub cev), tab sis lawv yuav tsis ua raws li cov kev cai teev tseg los ntawm ISO, yog li peb yuav tsum xyuam xim rau cov ntsiab lus hauv qab no:

 

i) Xim kub ── 5000K
ii) Xim rendering Performance index Ntau dua los yog sib npaug rau 90Ra
iii) Illuminance -- Illuminance (lux) -- nyob ntawm qhov chaw sim: lumens ib square meter (Ceeb Toom: Cov ntawv cim lub teeb lub raj qhia lumens nkaus xwb)

 

2. Cov ntaub ntawv vaj huam sib luag -- tsuav yog lawv nyob ze rau ISO specifications xws li:
