Cov xim rendering nyob rau hauv ib qho LED module, tseem hu ua chromaticity, yog ib qho kev ntsuas ntawm qhov tawg ntawm lub teeb xim. Kev sib kis ntawm lub teeb xim yog teev nyob rau hauv MacAdam thiab cov xim sib txawv tau teev tseg hauv MacAdam ellipses SDCM (Standard Deviation of Color Matching) raws li CIE 1964 tus qauv. Cov xim rendering lossis chromaticity yog muab qhab nia los ntawm MacAdam system ntawm qhov ntsuas ntawm 1-10 - qhov twg 1 qhia qhov zoo tshaj plaws chromaticity lossis xim zoo tshaj plaws ntawm lub teeb uas koj tuaj yeem ua tiav.
Nws tuaj yeem nyuaj rau pom qhov sib txawv / sib txawv ntawm cov xim ntawm 1 thiab 3 ntawm MacAdam nplai. Yog tias MacAdam tau siab dua qhov 3 ntawm qhov ntsuas, qhov sib txawv ntawm cov xim yuav pom tseeb dua, nyob ntawm qhov chaw uas lub teeb pom kev pom thiab txiav txim siab. Yog tias koj yuav tsum ntsuas cov xim rendering los ntawm phab ntsa ntxhua khaub ncaws los yog tsom teeb rau ntawm phab ntsa dawb, ces koj yuav pom tias LED-modules yuav tsum muaj tus nqi qis MacAdam. Lub teeb pom kev hauv tsev lossis sab hauv tsev feem ntau yuav tsum ncav cuag MacAdam qhov xav tau siab tshaj plaws ntawm 3 SDCM, thaum lub teeb pom kev sab nraum zoov feem ntau tuaj yeem txaus siab rau MacAdam ntawm 5 SDCM vim qhov chaw nyob ib puag ncig.
