Yini i-color binning kanye ne-SDMC?

Ukubekezelelana kombala: Kungumqondo ohlobene eduze nezinga lokushisa lombala. Lo mqondo ekuqaleni wawuhlongozwe ngu-Kodak embonini, iBritish i-Standard Deviation of Color Matching, ebizwa ngokuthi i-SDCM. Kungumehluko phakathi kwenani elibaliwe lekhompyutha kanye nenani elijwayelekile lomthombo wokukhanya okuqondiwe. Okusho ukuthi, ukubekezelelana kombala kunereferensi ethile kumthombo wokukhanya okuqondiwe.

Isisetshenziswa se-photochromic sihlaziya izinga lokushisa lombala lomthombo wokukhanya olinganisiwe, bese sinquma inani elijwayelekile lokushisa lombala we-spectral. Uma izinga lokushisa lombala lifana, inquma inani le-xy edidiyela umbala wayo kanye nomehluko phakathi kwayo nomthombo wokukhanya ojwayelekile. Uma kukhulu ukubekezelelana kombala, umehluko omkhulu wombala. Iyunithi yalokhu kubekezelelana kombala yi-SDCM,. Ukubekezelelana kwe-Chromatic kunquma umehluko kumbala okhanyayo wenqwaba yezibani. Ububanzi bokubekezelela umbala ngokuvamile buboniswa kugrafu njenge-ellipse kunendilinga. Imishini evamile yobungcweti inezinhlaka ezihlanganisa ukulinganisa idatha ethile, futhi ezinye izimboni zokupakisha ze-LED nezimboni zokukhanyisa zinemishini yobuchwepheshe ehlobene.

Sinomshini wethu wokuhlola esikhungweni sokuthengisa nasembonini, isampula ngayinye kanye nocezu lokuqala lokukhiqiza (kuhlanganise ne-COB LED STRIP, NEON FLEX, SMD LED STRIP NE-RGB LED STRIP) kuzohlolwa, futhi ukukhiqizwa ngobuningi kuzokwenziwa kuphela ngemva kokudlula. Isivivinyo.Siphinde sihlanganise ubuhlalu besibani ngokwethu, esingalawulwa kahle umgqomo wokukhanya kwe-strip ye-LED.

Ngenxa yemvelo eguquguqukayo yombala okhiqizwe ama-LED akhanyayo amhlophe, imethrikhi elula yokuveza ubukhulu bomehluko wombala phakathi kwenqwaba yama-LED inombolo yezinyathelo ze-ellipses ze-SDCM (MacAdam) ama-LED awela kuzo. Uma ama-LED wonke ewela ngaphakathi kwe-1SDCM (noma "isinyathelo esi-1 se-MacAdam ellipse"), abantu abaningi bazohluleka ukubona noma yimuphi umehluko ngombala. Uma ukuhluka kombala kufana nokuthi ukuhluka kwe-chromaticity kudlulele endaweni enkulu ngokuphindwe kabili (2 SDCM noma i-ellipse ye-MacAdam enezinyathelo ezimbili), uzoqala ukubona umehluko wombala. I-2-step MacAdam ellipse ingcono kunezoni enezinyathelo ezi-3, njalonjalo.

Kodwa-ke, kunezici eziningi ezithinta ukubekezelelana kombala, njengezizathu ze-chip ye-LED, isizathu sesilinganiso se-phosphor powder, isizathu sokushintsha kwamandla okushayela, kanye nesakhiwo sesibani sizothinta izinga lokushisa lombala. Isizathu sokuncipha kokukhanya nokuguga okusheshayo komthombo wokukhanya, ukushisa kombala kwe-LED nakho kuzokwenzeka ngesikhathi senqubo yokukhanyisa, ngakho-ke amanye amalambu manje acubungula izinga lokushisa lombala futhi akale izinga lokushisa lombala esimweni sokukhanyisa empeleni. isikhathi. Izindinganiso zokubekezelela umbala zihlanganisa izindinganiso zaseNyakatho Melika, izindinganiso ze-IEC, izindinganiso zaseYurophu nokunye. Isidingo sethu esijwayelekile sokubekezelelana kombala we-LED ngu-5SDCM. Ngaphakathi kwalolu hlu, amehlo ethu ahlukanisa ngokuyisisekelo ukuphuma kwe-chromatic.
