Chii chinonzi colour binning uye SDMC?

Kushivirira mavara: Ipfungwa ine chekuita nekupisa kwemavara. Pfungwa iyi yakatanga kutaurwa neKodak muindasitiri, iyo yeBritish inonzi Standard Deviation of Color Matching, inonzi SDCM. Ndiwo musiyano uripo pakati pekombuta inoverengwa kukosha uye kukosha kwakajairika kwechiedza chakanangana nacho. Kureva kuti, kushivirira mavara kune chirevo chaicho kune chiedza chakanangana nacho.

Muchina we photochromic unoongorora tembiricha yemavara echiedza chakayerwa, wobva waona tembiricha yemavara yakajairwa. Kana tembiricha yemavara yakafanana, inoona kukosha kwe coordinate yemavara ayo xy uye musiyano uripo pakati payo nechiedza chakajairwa. Kana tembiricha yemavara yakakura, musiyano wemavara unowedzera. Chikamu che tembiricha yemavara ichi iSDCM,. Tembiricha yeChromatic inoona musiyano muruvara rwechiedza chebhachi remwenje. Rudzi rwe color tolerance runowanzo kuratidzwa pagirafu se ellipse kwete denderedzwa. Midziyo yehunyanzvi ine mabhora anobatanidza kuyera data rakati, uye mamwe mafekitori e LED packaging nemafekitori emwenje ane michina yehunyanzvi yakafanana.

Tine muchina wedu wekuyedza uri munzvimbo yekutengesa uye mufekitori, sampuro yega yega uye chikamu chekutanga chekugadzira (kusanganisira COB LED STRIP, NEON FLEX, SMD LED STRIP UYE RGB LED STRIP) zvichaedzwa, uye kugadzirwa kwakawanda kuchaitwa chete mushure mekupasa bvunzo. Isu tinofukidzawo mabhero emwenje isu pachedu, ayo anogona kudzorwa zvakanaka nebhini remwenje we LED strip.

Nekuda kwehunhu hwemavara anogadzirwa nema LED machena, chiyero chiri nyore chekuratidza hukuru hwemusiyano wemavara mukati me batch yema LED inhamba yematanho eSDCM (MacAdam) ellipses ayo ma LED anowira maari. Kana ma LED ese ari mukati me SDCM imwe (kana "1-step MacAdam ellipse"), vanhu vazhinji havazooni mutsauko wemavara. Kana mutsauko wemavara wakadaro zvekuti mutsauko we chromaticity unosvika kunzvimbo yakakura kaviri (2 SDCM kana 2-step MacAdam ellipse), uchatanga kuona mutsauko wemavara. 2-step MacAdam ellipse iri nani pane 3-step zone, nezvimwewo.

Zvisinei, kune zvinhu zvakawanda zvinokanganisa kushivirira kwemavara, zvakaita sezvikonzero zvechip ye LED, chikonzero chehuwandu hwe phosphor powder, chikonzero chekuchinja kwe driving current, uye chimiro cherambi zvichakanganisawo tembiricha yemavara. Chikonzero chekudzikira kwekupenya uye kukurumidza kukwegura kwechiedza, kuyerera kwetembiricha yemavara ye LED kuchaitikawo panguva yekuvhenekesa, saka mamwe marambi ikozvino anofunga nezvetembiricha yemavara uye kuyera tembiricha yemavara mumamiriro emwenje munguva chaiyo. Mitemo yekushivirira mavara inosanganisira North America standards, IEC standards, European standards nezvimwewo. Chinodiwa chedu che LED color tolerance i5SDCM. Mukati meiyi range, maziso edu anonyanya kusiyanisa chromatic aberration.
