Nkag siab Xim Rendering Index (CRI) hauv LED Teeb pom kev zoo
Thaum xaiv LED teeb pom kev zoo, koj tuaj yeem ntsib lub sijhawmXim Rendering Index (CRI). Qhov kev ntsuas no ntsuas lub teeb lub peev xwm los nthuav tawm cov xim tseeb ntawm cov khoom piv rau lub teeb ntuj. CRI yog qhov tseem ceeb tshwj xeeb tshaj yog nyob rau hauv qhov chaw uas qhov tseeb xim tseem ceeb- xws li cov chaw ua yeeb yam, cov khw muag khoom, cov chaw kho mob, chaw ua haujlwm, thiab tsev cia puav pheej.
CRI tau qhab nia ntawm qhov ntsuas ntawm 0 txog 100. Tus lej siab dua, qhov tseeb dua qhov teeb pom kev zoo ua rau xim. CRI ntawm 80 thiab 90 yog suav tias yog qhov zoo, thaum 90 thiab siab dua yog qhov zoo heev. Nws tsim nyog sau cia tias CRI cuam tshuam los ntawm cov xim kub. Cov xim sov sov (piv txwv li, 2700K) tuaj yeem ua tiav CRI txog 100, thaum txias "hnub ci" kub nyob ib ncig ntawm 5000K feem ntau nyob nruab nrab ntawm 75 thiab 90.
Lub International Commission on Illumination (CIE) tau tsim cov qauv CRI los ntsuas seb cov teeb pom kev zoo li cas rov tsim cov xim. Qhov kev ntsuam xyuas piv cov teeb pom kev zoo rau qhov kev siv -xws li lub teeb incandescent (rau qhov kub siab tshaj 5000K) lossis hnub ci (rau cov siab dua 5000K). Qhov nruab nrab xim sib txawv raug rho tawm ntawm 100, ua rau tus nqi CRI. Ib qho CRI ze 100 txhais tau hais tias lub teeb sib tw nrog cov ntaub ntawv siv yuav luag zoo kawg nkaus.
Cov khoom siv hluav taws xob sib txawv ua haujlwm sib txawv hauv CRI:
Siab -Siv paug tawm (HID)Lub teeb feem ntau muaj CRI tsawg heev (ze 0)
Fluorescent teeb feem ntau poob qis dua 60
LEDs muaj ntau yam CRI, feem ntau ntawm 70 txog 98
Txawm hais tias koj tab tom siv LED strips, teeb pom kev zoo, qhov muag teev, lossis cov khoom siv sib txuas, xaiv qhov siab -CRI cov khoom ua kom cov xim raug zoo dua thiab pom kev nplij siab.
