Nkag siab CRI & Vim li cas Nws tseem ceeb nrog LED Teeb
Yog tias koj tau saib mus rau hauv lub teeb pom kev zoo lossis lub teeb pom kev zoo, tej zaum koj tuaj yeem hla lub sijhawm CRI, uas feem ntau ua raws li tus lej. Cov ntawv luv rau Xim Rendering Index yog CRI. Nws yog ib lub tswv yim uas koj yuav tsum paub yog tias koj mob siab rau kev txhim kho cov neeg nyob hauv koj lub tsev lossis chaw ua haujlwm, nrog rau cov chaw ntawd. Txuas ntxiv nyeem rau peb cov lus piav qhia ncaj nraim ntawm CRI thiab kev piav qhia ntawm nws qhov tseem ceeb.
Lub ntsiab lus ntawm CRI
Thawj yam ua ntej, xim kub thiab xim rendering Performance index yuav tsum tsis txhob totaub nrog ib leeg. Qhov sov los yog txias ntawm lub teeb pom kev zoo yog qhia los ntawm cov xim kub, uas yog ntsuas hauv Kelvin. Cov cua kub uas sov dua thiab muaj lub ntsej muag daj yog qhov zoo dua rau kev tsim kom muaj qhov chaw zoo rau kev so, xws li hauv tsev noj mov; Txawm li cas los xij, qhov kub thiab txias uas nruab nrab lossis txias dua feem ntau ua rau cov dej num thiab chaw ua haujlwm hauv kev lag luam thiab kev lag luam.
Txawm hais tias xim kub yog qhov tseem ceeb heev, qhov kev xaiv uas koj ua hauv cheeb tsam no feem ntau yuav txiav txim siab los ntawm koj tus kheej nyiam thiab ib puag ncig uas koj yuav teeb pom kev zoo. CRI, ntawm qhov tod tes, tsis tshua muaj kev cuam tshuam los ntawm cov kev hloov pauv no feem ntau. Feem ntau, CRI siab dua yog qhov zoo dua, ob qho tib si rau tib neeg thiab qhov chaw.
CRI yog ib qho luv luv rau cov xim rendering Performance index, thiab nws piav qhia txog yuav ua li cas xim xim (los yog tib neeg) qhia los ntawm lub teeb ci. CRI piv cov tsos ntawm ib yam khoom nyob rau hauv ntau yam teeb pom kev zoo rau yuav ua li cas nws yuav tshwm sim nyob rau hauv incandescent teeb pom kev zoo los yog ntuj tshav ntuj, siv ib tug naj npawb ntawm scale ntawm ib tug mus rau ib puas los ntsuam xyuas cov xim rendition thiab xim raug ntawm cov khoom. Lub teeb ci ntsa iab thiab tshav ntuj raug xa mus rau "blackbody radiators," thiab ob qho tib si muaj CRI tus qhab nia ntawm 100, ua rau lawv tus qauv ntsuas xim. Cov xim rendition ntawm lub teeb fixture los yog lub teeb yog hais tias yuav zoo dua thaum lub CRI ntsuam xyuas muaj tus lej ntau dua. Ib qho CRI ntawm 80 lossis siab dua yog suav tias yog qhov zoo, qhov CRI ntawm 90 lossis ntau dua yog suav tias yog qhov zoo heev. Feem ntau, CRI ntawm 80 lossis siab dua yog suav tias yog qhov zoo. Xav txog CRI cov lej zoo ib yam li cov qhab nia xeem: Xyoo 1980s yog B, thaum xyoo 1990 yog A.
Vim li cas CRI thiaj yog qhov loj heev
Vim li cas qhov tseeb xim luam tawm yog qhov tseem ceeb? Nws yog qhov ua tau rau nws los ua ib qho tseem ceeb hauv txhua qhov chaw, los ntawm koj lub tsev mus rau koj qhov chaw ua haujlwm. Txawm li cas los xij yog illuminated los ntawm lub teeb uas muaj CRI tsawg yuav coj cov xim uas yog monotone thiab ntxuav tawm. Qhov no tuaj yeem xa mus rau cov khoom uas muaj xim dab thiab npub. Thaum nws los txog rau tib neeg, qhov no tuaj yeem tshwm sim raws li mob tawv nqaij tones thiab ob lub qhov muag uas tsis kaj siab thiab tsis muaj sia.
Ntawm qhov tod tes, teeb pom kev zoo nrog CRI siab tuaj yeem ua rau koj ib puag ncig nrog lub neej zoo thiab ua haujlwm. Muaj CRI siab yuav ua rau cov xim ntawm cov rooj tog zaum, khaub ncaws, zaub mov, thiab lwm yam khoom "pop," uas yuav ntxiv cov nplua nuj nuances rau lub rooj tsim qauv uas koj tau teeb tsa. Qhov kev qhuas zoo no raug xa mus rau cov tib neeg. Cov neeg yuav tshwm sim kom muaj cov tawv nqaij nplua nuj thiab ci ntsa iab thiab noj qab nyob zoo yog tias CRI siab. Tus nqi CRI siab yog qhov tseem ceeb tshwj xeeb tshaj yog rau cov xim tseem ceeb thiab ib puag ncig, uas yog cov kev thov kom zoo nkauj, kev nthuav qhia, thiab cov xim luam tawm yog qhov tseem ceeb rau kev ua tiav ntawm kev lag luam. Qhov no siv rau cov khw muag khoom lag luam, uas yuav tsum tau hais txog cov khaub ncaws muaj yeeb yuj; cov khw muag khoom noj, uas yuav tsum ua kom cov zaub mov thiab tsim kom zoo nkauj; thiab txawm tias kev lag luam vaj tse, uas yuav tsum paub tias ua kom muaj vaj tse zoo li vivid thiab caw tuaj yeem pab nws muag.
Cov laj thawj hauv qab qhov loj hlob tseem ceeb ntawm CRI
Thaum lub teeb ci incandescent yog tus qauv, xim rendering Performance index (CRI) tsis tseem ceeb. Qhov no yog vim lub fact tias incandescents muaj cov xim rendering zoo heev.
Uas yog ua ntej qhov muag teev incandescent pib ploj mus los ntawm lub teeb pom kev zoo, uas feem ntau yog vim qhov tseeb tias lawv muaj kev ua haujlwm tsawg ntawm kev siv lub zog. Thaum pib, lawv tau hloov tawm nrog cov teeb fluorescent, uas ua haujlwm zoo dua tag nrho. Nyob rau hauv xyoo tas los no, lub teeb-emitting diode (LED) qhov muag teev tau tshwm sim los ua lwm txoj hauv kev rau cov teeb pom kev fluorescent.
Txawm hais tias piv rau lwm lub teeb pom kev zoo, xws li fluorescents, LEDs tau raug qhuas rau lawv qhov tshwj xeeb ntawm kev siv hluav taws xob. Lawv kuj muaj lwm yam zoo, xws li lub neej ntev. Tsis tas li ntawd, lawv tsis tawg thiab tsis muaj cov mercury uas ua rau muaj kev phom sij. Yog li ntawd, tam sim no lub baton rau teeb pom kev zoo tau dhau los ntawm fluorescents mus rau LEDs.
LED teeb pom kev zoo thiab CRI Scale
Kev siv cov LEDs, tsis zoo li cov teeb pom kev zoo fluorescent, kuj muaj lwm qhov zoo dua. Lawv muaj peev xwm muab CRI siab dua. Txawm hais tias koj tab tom chais plaub hau lossis siv tshuaj pleev ib ce rau pem hauv ntej ntawm koj chav dej iav hauv tsev, teeb duab kos duab rau ntawm phab ntsa lossis teeb pom kev ntawm lub qhov rais ntawm lub khw, qhov no qhia tau tias koj yuav muaj peev xwm txaus siab rau cov xim uas ci dua thiab muaj tseeb rau lub neej.
Muaj ntau yam xim-rendering peev xwm ntawm ntau hom teeb pom kev zoo. Nyob rau hauv qab, piv txwv li, koj yuav pom high-pressure sodium thiab mercury-vapor teeb, txhua tus muaj CRI uas yog kwv yees li 24 los yog 49, feem. Txawm hais tias tsis muaj lub teeb tuaj yeem sib npaug ntawm cov xim zoo nkauj, qee qhov muag teev ua haujlwm zoo nkauj ntawm nws. Txawm hais tias koj yuav tsum xaiv, qee qhov teeb pom kev zoo, piv txwv li, tuaj yeem tsim CRI uas txaus siab. Cov xim rendering Performance index (CRI) ntawm fluorescents tuaj yeem nyob qhov twg los ntawm 50 txog 85, nyob ntawm cov txheej. Yog tias koj xaiv qhov zoo tshaj plaws fluorescents, koj tuaj yeem ua tiav cov xim zoo nkauj, tab sis tsis zoo.
CRI ntawm cov LEDs niaj hnub no, ntawm qhov tod tes, tuaj yeem ncav cuag 90s. Yog tias koj xaiv lub LED uas muaj CRI siab, ces koj yuav ua tiav cov xim uas ze heev rau cov uas tsim los ntawm lub teeb ntuj. Qhov no yuav yog ib qho tseem ceeb tshwj xeeb hauv cov chaw lag luam xws li cov khw noj mov thiab cov khw muag khoom uas tab tom nrhiav rau cov xim ntuj uas txaus siab rau lub qhov muag, nrog rau cov tsev uas koj xav kom txhua tus saib thiab xav tias lawv zoo tshaj plaws thaum tseem ua kom koj lub tsev zoo tshaj plaws. .
Qhov tseeb tias LED teeb nrog zoo heev thiab siab CRI ntsuam xyuas tsis raug nqi ntau dua li cov uas muaj qhov zoo CRI kev ntsuas yog nyob deb ntawm qhov zoo tshaj plaws ntawm cov teeb no. Thaum xav txog cov txiaj ntsig ntawm cov xim ntuj tsim, nws tuaj yeem ua tau zoo los nqis peev me ntsis nyiaj ntxiv kom tau txais CRI siab dua. Qhov no tuaj yeem them tawm ntau txoj hauv kev. Tsis tas li ntawd, raws li kev txhim kho tsis tu ncua ntawm LED thev naus laus zis, LED kev ua tau zoo tseem txhim kho thaum lawv cov nqi txuas ntxiv txo.
Thov qhia rau peb paub yog tias koj muaj lus nug lossis lus hais txog cov xim uas koj pom hauv koj lub ntiaj teb. Tsuas yog hu rau peb los yog xa email tuaj rau peb.
