Xim rendering Performance index (CRI) yog dab tsi?
Cov xim rendering Performance index ntawm lub teeb qhov chaw yog hais txog qhov parameter ntawm lub teeb lub peev xwm los kho cov xim ntawm ib yam khoom. Nws yog tsuas yog siv los txheeb xyuas qhov sib txawv ntawm cov xim ntawm LED qhov chaw. Cov qhab nia ntawm qhov ntsuas no nyob ntawm 0 txog 100.
Txhawm rau muab nws yooj yim: xim rendering yog ib qho tseem ceeb rau kev ntsuam xyuas lub teeb pom kev zoo, thiab xim rendering Performance index yog ib qho tseem ceeb rau kev ntsuam xyuas cov xim rendering ntawm lub teeb. Nws yog ib qho tseem ceeb rau kev ntsuas cov yam ntxwv xim ntawm cov khoom siv hluav taws xob. Qhov siab dua qhov xim rendering Performance index, qhov zoo dua qhov xim rendering ntawm lub teeb ci. Qhov zoo ntawm cov xim, qhov muaj zog ntawm cov xim rov qab muaj peev xwm ntawm cov khoom.
Lub International Commission on Illumination (CIE) txhais cov xim rendering xws li: cov nyhuv ntawm lub teeb ci ntawm cov xim ntawm cov khoom piv nrog cov qauv siv teeb pom kev zoo.
General xim rendering Performance index: Qhov loj Ra, qhov zoo dua cov xim rendering kev ua tau zoo; ntawm qhov tsis sib xws, qhov phem tshaj qhov xim rendering kev ua tau zoo. Cov xim rendering Performance index ntawm lub hnub yog txhais raws li 100.
Txawm hais tias "xim rendering Performance index" tsis sawv cev txhua yam txog lub teeb. Tab sis "siab CRI" tuaj yeem txiav txim siab qhov cuam tshuam ntawm lub teeb pom kev zoo - siab xim luam tawm.
As shown in the figure below: a light source with a CRI (Ra) >90 muaj ib qho kev nthuav qhia muaj zog ntawm cov xim xim ntawm ib yam khoom dua li lub teeb ci nrog CRI (Ra)<80, making it more visually comfortable.
CRI sib piv
Lub International Commission on Illumination (CIE) teev cov xim rendering Performance index ntawm lub hnub ci li 100 thiab teev 15 xeem xim, siv R1-R15 los sawv cev rau cov zaub Performance index ntawm 15 xim raws li. Thaum muab piv rau lub teeb ci rau ib qho kev siv lub teeb pom kev, qhov ntsuas tus nqi ntawm 100 yog qhov zoo tshaj.BENWEI tuam txhab tuaj yeem ncav cuag CRI 99 tam sim no
Ra feem ntau yog hais txog tus nqi nruab nrab ntawm yim lub ntuj xim kho kom zoo nkauj ntawm R1-R8 los ntawm lub teeb ci. R9-R15 tsis suav nrog hauv kev suav. Txawm li cas los xij, thaum ntsuas qhov teeb pom kev zoo CRI los ntawm kev pom kev tshaj lij, qhov tsis zoo ntawm R9 (txo liab) thiab R15 (kev ua tau zoo ntawm Asian tawv tones) yuav tsum tau txiav txim siab.
Since LED lamps use blue chips to excite yellow phosphor to produce white light, it is extremely lacking in the red band, resulting in LED lamps having no red display capability. When we choose LED lamps, we must not only look at the color rendering index Ra, but also the values of R9 and R15. Generally, the display indicators of lamps are recommended to be Ra>90 (R9>50, R15>90).
Qhov sib txawv ntawm cov xim rendering index:
90-100 Cov chaw uas xav tau cov xim sib txawv, xws li teeb pom kev hauv tsev cia puav pheej;
80-89 Qhov chaw uas yuav tsum tau txiav txim xim kom raug;
60-79 Cov chaw yuav tsum muaj xim nruab nrab rendering;
40-59 Cov chaw uas tsis muaj qhov yuav tsum tau ua ntawm cov xim rendering thiab xim txawv me me;
20-39 Qhov chaw uas tsis muaj cov cai tshwj xeeb rau kev ua xim xim.
Hauv kev tsim teeb pom kev zoo hauv tsev, tsim kom muaj chaw noj qab haus huv thiab zoo, kev xaiv kom raug ntawm cov teeb pom kev zoo thiab teeb pom kev zoo yog qhov tseem ceeb. Txhawm rau ua kom tib neeg lub ntsej muag zoo dua thiab cov xim ntawm cov zaub mov thiab cov txiv hmab txiv ntoo muaj tseeb dua hauv lub neej niaj hnub, thaum xaiv cov teeb, qhov siab dua CRI, qhov zoo dua, uas yog, tus nqi RA (R9, R15) yuav tsum siab.
Lub teb chaws tus txheej txheem teev tseg tias cov xim rendering Performance index RA ntawm cov teeb pom kev zoo sab hauv tsev yog tsawg kawg yog 80. Txawm li cas los xij, Luo Hualu, tus tsim teeb pom kev zoo ntawm Mizhi Space, tau taw qhia tias los ntawm lub hauv paus ntsiab lus ntawm kev siv lub teeb pom kev zoo, peb xav kom CRI RA ntau dua. 90 thaum tsim teeb pom kev zoo thiab cov khoom sib xws. Qhov zoo tshaj plaws lub teeb yog lub teeb ntuj, uas nws cov xim rendering Performance index yog txhais raws li 100. Tam sim no, lub teeb zoo tshaj plaws nyob rau hauv lub ntiaj teb no tsuas yog infinitely ze rau 100.BENWEI Company can reach 95 , R9>90, R12>90
