Chii chinonzi color binning uye SDMC?

Kushivirira kwemavara: Ipfungwa ine hukama zvakanyanya nekudziya kwemavara. Iyi pfungwa yakatanga kutaurwa naKodak muindasitiri, iyo yeBritish ndiyo Standard Deviation yeColor Matching, inonzi SDCM. Ndiwo mutsauko pakati pekombuta yakaverengerwa kukosha uye mwero kukosha kwechinangwa chemwenje sosi. Izvi zvinoreva kuti, kushivirira kwemavara kune chirevo chaicho kune chinangwa chechiedza.

Iyo photochromic midziyo inoongorora tembiricha yeruvara yeyakayerwa sosi yemwenje, yobva yaona iyo yakajairwa spectral color tembiricha kukosha. Kana tembiricha yeruvara yafanana, inosarudza kukosha kweruvara rwayo coordinate xy uye mutsauko uripo pakati payo neyakajairwa mwenje sosi. Iyo yakakura kushivirira kwemavara, iyo yakakura kusiyana kwemavara. Iyo unit yeiyi ruvara kushivirira ndeyeSDCM,. Chromatic tolerance inosarudza mutsauko muruvara rwechiedza chebhechi remwenje. Rudzi rwekushivirira kweruvara runowanzo kuratidzwa pagirafu se ellipse kwete denderedzwa. General hunyanzvi michina ine kubatanidza nzvimbo kuyera chaiyo data, uye mamwe mafekitori ekurongedza e LED uye mafekitori ekuvhenekesa ane hukama nehunyanzvi.

Tine yedu yekuyedza muchina munzvimbo yekutengesa uye fekitori, imwe neimwe sampuli uye yekutanga chidimbu chekugadzira (kusanganisira COB LED STRIP, NEON FLEX, SMD LED STRIP UYE RGB LED STRIP) ichaedzwa, uye kugadzirwa kwakawanda kunozoitwa chete mushure mekupfuura. bvunzo.Isu zvakare tinoputira mabheji emwenje isu pachedu, ayo anogona kunyatsodzorwa bhini re LED strip mwenje.

Nekuda kwekusiyana kwerudzi rwemuvara unogadzirwa nemwenje machena ma LEDs, metric yakakunakira yekuratidza hukuru hwekusiyana kwemavara mukati mebatch ye LEDs nhamba yeSDCM (MacAdam) ellipses matanho ayo ma LED anowira mukati. Kana ma LED ese akawira mukati me1 SDCM (kana "1-nhanho MacAdam ellipse"), vanhu vazhinji vangatadza kuona chero musiyano muvara. Kana kusiyanisa kwemavara kuri zvekuti kusiyanisa kwechromaticity kunosvika kune imwe nzvimbo yakakura zvakapetwa kaviri (2 SDCM kana 2-nhanho MacAdam ellipse), iwe unozotanga kuona imwe mutsauko weruvara. A 2-nhanho MacAdam ellipse iri nani pane 3-nhanho zone, zvichingodaro.

Nekudaro, pane zvinhu zvakawanda zvinokanganisa kushivirira kwemavara, sezvikonzero zveiyo LED chip, chikonzero cheiyo reshiyo yehupfu phosphor, chikonzero chekuchinja kwekutyaira ikozvino, uye chimiro chemwenje chichakanganisawo tembiricha yemavara. Chikonzero chekudzikira kwekupenya uye nekukurumidzira kuchembera kwemwenje sosi, kupisa kwemavara kwe LED kuchaitikawo panguva yekuvhenekesa, saka mamwe marambi ikozvino anofunga tembiricha yemavara uye kuyera kupisa kwemavara munzvimbo yekuvhenekesa mune chaiyo. nguva. Mavara ekushivirira zviyero anosanganisira North America zviyero, IEC zviyero, European zviyero uye zvichingodaro. Chido chedu chese che LED kushivirira kwemavara ndeye 5SDCM. Mukati memhando iyi, maziso edu anonyanya kusiyanisa chromatic aberration.
