CRI: Nws yog dab tsi?
Qhov tseeb ntawm cov xim tiag tiag ntawm lub teeb pom kev pom cov khoom, tib neeg, thiab ib puag ncig ib puag ncig raug xa mus rau cov xim rendering Performance index, los yog CRM.
1. Tus nqi ntawm cov xim rendering Performance index (CRI)
Tus lej siab tshaj yog 100, thiab tus lej ntau dua, qhov kev txawj ntse dua. Tus qhab nia CRI ntawm 60–85 yog Qhov Zoo, qhov qhab nia tsawg dua 55 feem ntau suav tias yog Neeg pluag, thiab qhov ntsuas ntawm 90 lossis ntau dua yog suav tias yog Zoo heev.
2.Qhov thib ob metric rau ntsuas cov khoom siv hluav taws xob yog cov xim rendering Performance index (CRI).
Txhawm rau txiav txim siab cov xim zoo ntawm LED fixtures, koj tuaj yeem sib piv lawv rau cov teeb pom kev zoo lossis hnub ci teeb raws li Xim Kub (CCT). Raws li CRI tus qauv, xim kub hauv qab 5000K yuav tsum tau sawv cev los ntawm Planckian hluav taws xob spectrum, thaum xim kub siab tshaj 5000K yuav tsum sawv cev los ntawm lub hnub ci spectrum.
Lus Cim: Lub Planckian hluav taws xob spectrum tej zaum yuav xav tias yog lub teeb ci ntawm lub teeb thiab halogen teeb. Hnub ci spectrum yog nyob ntawm cov xim kub ntawm LED kom rov ua dua lub teeb sib npaug ntawm lub hnub.
3. Cov Xim Rendering Index (CRI) piv thiab ntsuas qhov khoom ntawm cov xim uas muaj nyob rau hauv lub teeb pom kev zoo.
Ib cov qauv kuaj xim (TCS) raug rau ib qho teeb pom kev zoo thiab ib hnub twg los yog lub teeb ci; cov xim reflected yog ces ntsuas. Thaum kawg, suav cov CRI ntawm lub teeb ci los ntawm qhov nruab nrab ntawm txhua qhov kev xav ntawm cov xim, lossis "R" (yuav muaj 8 lossis 15 pcs ntawm cov xim xav).
Nws yog qhov zoo dua los xa mus rau CRI (R1–R8) lossis "CRI (Ra)" thaum tham txog nws. Siv "CRI(e)", "Re", lossis txuas ntxiv CRI (R1-R15) thaum tham txog txuas ntxiv CRI. Thov nco ntsoov tias thaum hais txog CRI, XSY Teeb pom kev zoo cov khoom tshwj xeeb hais txog CRI(Ra).
Nws tseem ntseeg tau tias qhov ntau dua tus nqi CRI, lub peev xwm muaj zog dua, raws li qhov kev sim qhia tau hais tias lub teeb ci nrog CRI nyob ib ncig ntawm 100 nthuav tawm cov xim uas zoo ib yam li txoj kev siv lub teeb qhia tib xim.
Lub siab CRI LED teeb pom kev zoo yog dab tsi?
Txhawm rau teeb pom qhov sib txawv, siv LED teeb nrog sib txawv CRIs (Ra). Cov xim zoo li qub nrog qis CRI ntawm sab laug tsis zoo li cov uas muaj CRI siab ntawm sab xis, raws li cov lus piav qhia. LED fixture yog suav tias yog siab CRI yog tias nws tus nqi CRI ntau dua 90.
