CCT ntsuas qhov tseeb xim ntawm lub teeb uas tsim nyob rau hauv Kelvins thiab tsis muaj dab tsi ua rau lub teeb pom kev zoo.
Xim Rendering Index (CRI) yog dab tsi?
Xim Rendering Performance index (CRI) yog ib qho kev ntsuas kom muaj nuj nqis ntawm lub peev xwm ntawm lub teeb ci los qhia cov xim ntawm ntau yam khoom ncaj ncees nyob rau hauv kev sib piv nrog lub ntuj lossis cov qauv teeb pom kev zoo. Cov teeb pom kev zoo uas muaj CRI siab yog qhov tsim nyog rau cov xim tseem ceeb xws li kev saib xyuas menyuam yaus thiab kho duab kos duab. Nws yog txhais los ntawm International Commission on Illumination (CIE) raws li hauv qab no:
Xim rendering: Cov nyhuv ntawm lub teeb pom kev ntawm cov xim ntawm cov khoom los ntawm kev nco qab lossis kev sib piv nrog rau lawv cov xim nyob rau hauv ib qho kev siv lossis tus qauv illuminant.
CRI ntawm lub teeb ci tsis qhia qhov pom tseeb xim ntawm lub teeb ci; cov ntaub ntawv no tau muab los ntawm qhov sib txheeb xim kub (CCT). CRI yog txiav txim los ntawm lub teeb qhov chaw spectrum. Lub teeb incandescent muaj qhov txuas txuas ntxiv; Lub teeb fluorescent muaj ib txoj kab sib cais, txhais tau hais tias lub teeb incandescent muaj CRI siab dua.
Tus nqi feem ntau hais tias "CRI" ntawm cov khoom lag luam muaj teeb pom kev zoo yog hu ua CIE Ra tus nqi, "CRI" yog ib lo lus dav dav thiab CIE Ra yog tus qauv thoob ntiaj teb cov xim rendering Performance index.
Piv txwv li, qhov siab tshaj plaws tau CIE Ra tus nqi yog 100 thiab tsuas yog muab rau ib qhov chaw uas nws cov spectrum zoo ib yam rau lub spectrum ntawm nruab hnub nrig, ze heev rau ntawm lub cev dub (cov teeb incandescent yog lub cev dub zoo), poob rau qhov tsis zoo rau qee qhov chaw teeb pom kev zoo. Tsawg-siab sodium teeb pom kev zoo muaj qhov tsis zoo CRI; Lub teeb fluorescent muaj li ntawm 50 rau hom yooj yim, txog li 98 rau ntau hom phosphor zoo tshaj. Cov xim dawb-xim LEDs muaj CRI ntawm 80, 90, lossis ntau dua.
Spectral Power Distribution
Qhov pom ntawm electromagnetic spectrum yog tsim los ntawm hluav taws xob nrog wavelengths ntawm kwv yees li 400 txog 750 nanometers. Qhov xiav ntawm qhov pom spectrum yog qhov luv wavelength, thiab qhov liab yog qhov ntev wavelength nrog tag nrho cov xim gradations nyob nruab nrab.
Spectral fais fab faib graphs qhia qhov txheeb ze zog ntawm wavelengths thoob plaws qhov pom spectrum rau ib lub teeb ci. Cov duab no kuj qhia txog lub peev xwm ntawm lub teeb ci los ua txhua yam lossis xaiv xim.
Hauv qab no saib yuav ua li cas ib tug raug spectral zog faib graph rau nruab hnub nrig.
