Dab tsi yog LED teeb pom kev zoo nrog CRI siab?
Piv nrog rau thaum lub teeb incandescent yog qhov tseem ceeb thev naus laus zis, muaj ntau ntau yam uas yuav tsum tau coj mus rau hauv tus account thaum yuav LED teeb. Cov xim rendering Performance index (CRI), uas ntsuas lub teeb lub peev xwm rau kev ncaj ncees tsim cov xim, yog ib qho tshwj xeeb uas tau txais kev saib xyuas ntau dua. Cia peb siv sijhawm ib feeb tham txog siab CRI hauv kev cuam tshuam rau LED teeb. Nws yog qhov tseem ceeb kom nkag siab tias CRI yog dab tsi txhawm rau nkag siab tias vim li cas CRI siab yog qhov tseem ceeb; Yog tias koj tsis paub meej, tsis txhob txhawj; koj tuaj yeem nrhiav cov ntaub ntawv ntxiv hauv peb cov ntawv ua ntej. Ib txoj hauv kev los sib piv cov teeb ci LED sib txawv yog siv qhov ntsuas CRI, uas nyob ntawm 0 mus txog 100. Koj tuaj yeem pom tias kev siv CRI ntawm 89 yuav tsim cov xim nplua nuj dua li muaj CRI ntawm 80, uas yog dab tsi Tam sim no feem ntau ntawm LED qhov muag teev muaj. High CRI LEDs txhais tau tias yog LED teeb nrog CRI ntawm siab dua 90.
Txij li thaum koj tsis tas yuav xav txog ib qho ntawm qhov no thaum siv lub teeb pom kev zoo, tag nrho cov no yuav zoo li tsis paub rau koj. Lub CRI ntawm lub teeb incandescent yog 100, thiab nws txo qis los ntawm qhov ntawd.
Cov neeg siv khoom siv teeb pom kev zoo LED tseem tsis tau nqa qhov ntsuas qhov ntsuas; Feem ntau ntawm CFL qhov muag teev muaj CRI ntawm 80. Qhov no ua rau cov neeg tsim khoom tsim teeb pom kev zoo uas yog nyob rau hauv cov xim fidelity thiab muaj CRI ntawm 90 lossis siab dua. Los ntawm kev ua li ntawd, lawv yuav pib coj tus cwj pwm zoo li cov teeb pom kev zoo nyob rau sab hauv thaum tseem pib zoo li lawv sab nraud.
Txheeb xyuas cov khoom lag luam cov ntaub ntawv teeb pom kev zoo kom pom qhov twg nws nyob ntawm CRI nplai kom paub tseeb tias koj tab tom yuav lub teeb ci siab CRI LED.
Ua ntej txog tam sim no, siab CRI qhov muag teev tsuas yog pom nyob rau hauv cov tsev noj mov high-end lossis cov chaw kos duab, tab sis vim muaj ntau txoj hauv kev thiab cov nqi pib poob, kev saws me nyuam pib tuaj tos. California Energy Commission tau tsim txoj cai lij choj hauv California uas yuav maj mam txhawb ntau tus neeg xaiv lub teeb pom kev zoo no.
Txawm hais tias tsis yog txhua tus neeg tsim khoom tau tsim lub siab CRI LED qhov muag teev, Soraa thiab Cree twb tau ua ntau lub siab CRI LEDs siv tau. Tag nrho cov kab dej nyab thiab teeb pom kev los ntawm Soraa muaj nyob rau hauv MR16 LED, AR111, PAR30, thiab PAR38 xaiv. High CRI 40W thiab 60W lub tsev LED qhov muag teev muaj nyob ntawm Cree.
Lub Cree TrueWhite LED teeb nrog CRI ntawm 93 tau tshuaj xyuas los ntawm Cnet, thiab nws tau sib piv nrog lub teeb pom kev zoo tib yam LED (sab laug). Koj tuaj yeem pom tias muaj qhov txawv ntawm cov duab saum toj no, tab sis lawv tej zaum tsis tseem ceeb txaus rau cov neeg feem coob tam sim ntawd tawm mus thiab hloov tag nrho lawv cov teeb ci LED tam sim no rau siab CRI. Nws txhais li cas tiag tiag yog tias peb maj mam txav deb ntawm LED thev naus laus zis lub zog ua haujlwm thiab mus rau lub teeb pom kev zoo.
