Xim binning thiab SDMC yog dab tsi?

Kev kam rau xim: Nws yog lub tswv yim uas muaj feem cuam tshuam nrog qhov kub ntawm xim. Lub tswv yim no tau pib los ntawm Kodak hauv kev lag luam, Askiv yog Standard Deviation of Color Matching, hu ua SDCM. Nws yog qhov sib txawv ntawm tus nqi xam los ntawm lub khoos phis tawj thiab tus nqi txheem ntawm lub hom phiaj teeb pom kev zoo. Uas yog hais tias, kev kam rau xim muaj qhov siv tshwj xeeb rau lub hom phiaj teeb pom kev zoo.

Cov khoom siv photochromic tshuaj xyuas qhov kub ntawm cov xim ntawm qhov ntsuas lub teeb, thiab tom qab ntawd txiav txim siab tus nqi kub xim spectral txheem. Thaum qhov kub xim zoo ib yam, nws txiav txim siab tus nqi ntawm nws cov xim sib koom ua ke xy thiab qhov sib txawv ntawm nws thiab qhov chaw teeb pom kev zoo txheem. Qhov loj dua qhov kev kam rau xim, qhov sib txawv xim ntau dua. Lub chav ntawm qhov kev kam rau xim no yog SDCM,. Kev kam rau Chromatic txiav txim siab qhov sib txawv ntawm cov xim teeb ntawm ib pawg ntawm cov teeb. Qhov ntau yam kev kam rau xim feem ntau yog qhia ntawm daim duab ua lub ellipse es tsis yog lub voj voog. Cov khoom siv kev tshaj lij dav dav muaj cov pob zeb sib xyaw ua ke los ntsuas cov ntaub ntawv tshwj xeeb, thiab qee lub Hoobkas ntim LED thiab cov Hoobkas teeb pom kev zoo muaj cov khoom siv kev tshaj lij cuam tshuam.

Peb muaj peb lub tshuab kuaj hauv chaw muag khoom thiab lub Hoobkas, txhua tus qauv thiab thawj daim ntawm kev tsim khoom (xws li COB LED STRIP, NEON FLEX, SMD LED STRIP THIAB RGB LED STRIP) yuav raug kuaj, thiab kev tsim khoom loj tsuas yog ua tom qab dhau qhov kev xeem. Peb kuj tseem muab cov hlaws teeb rau peb tus kheej, uas tuaj yeem tswj tau lub thoob khib nyiab ntawm LED strip teeb.

Vim yog qhov sib txawv ntawm cov xim uas tsim los ntawm cov teeb dawb LEDs, ib qho yooj yim metric rau kev qhia txog qhov sib txawv ntawm cov xim hauv ib pawg ntawm LEDs yog tus lej ntawm SDCM (MacAdam) ellipses kauj ruam uas cov LEDs poob rau hauv. Yog tias cov LEDs tag nrho poob rau hauv 1 SDCM (lossis "1-kauj ruam MacAdam ellipse"), feem ntau cov neeg yuav tsis pom qhov sib txawv ntawm cov xim. Yog tias qhov sib txawv ntawm cov xim yog xws li qhov sib txawv ntawm chromaticity nthuav dav mus rau thaj chaw uas yog ob npaug loj (2 SDCM lossis 2-kauj ruam MacAdam ellipse), koj yuav pib pom qee qhov sib txawv ntawm cov xim. 2-kauj ruam MacAdam ellipse zoo dua li 3-kauj ruam cheeb tsam, thiab lwm yam.

Txawm li cas los xij, muaj ntau yam uas cuam tshuam rau qhov xim kam rau siab, xws li cov laj thawj rau LED chip, qhov laj thawj rau qhov piv ntawm phosphor hmoov, qhov laj thawj rau kev hloov pauv ntawm qhov tam sim no tsav tsheb, thiab cov qauv ntawm lub teeb kuj tseem yuav cuam tshuam rau qhov kub xim. Qhov laj thawj rau qhov txo qis ntawm qhov kaj thiab qhov laus ntawm lub teeb, qhov kub xim ntawm LED kuj tseem yuav tshwm sim thaum lub sijhawm teeb pom kev zoo, yog li qee lub teeb tam sim no xav txog qhov kub xim thiab ntsuas qhov kub xim hauv lub xeev teeb pom kev zoo hauv lub sijhawm tiag tiag. Cov qauv kev kam rau siab xim suav nrog North American cov qauv, IEC cov qauv, European cov qauv thiab lwm yam. Peb qhov yuav tsum tau ua rau LED xim kam rau siab yog 5SDCM. Hauv qhov ntau no, peb lub qhov muag feem ntau paub qhov txawv ntawm chromatic aberration.
