Kuyini ukubopha imibala kanye ne-SDMC?

Ukubekezelelana kombala: Umqondo ohlobene kakhulu nokushisa kombala. Lo mqondo waphakanyiswa ekuqaleni yiKodak embonini, iBritish iyi-Standard Deviation of Color Matching, ebizwa ngokuthi i-SDCM. Umehluko phakathi kwenani elibalwe yikhompyutha kanye nenani elijwayelekile lomthombo wokukhanya okuqondiwe. Okusho ukuthi, ukubekezelelana kombala kunokubhekisela okuthile emthonjeni wokukhanya okuqondiwe.

Imishini ye-photochromic ihlaziya ububanzi bokushisa kombala bomthombo wokukhanya olinganisiwe, bese inquma inani lokushisa lombala we-spectral elijwayelekile. Uma izinga lokushisa lombala lifana, linquma inani le-xy yombala wayo kanye nomehluko phakathi kwayo nomthombo wokukhanya ojwayelekile. Uma ukubekezelelana kombala kukhulu, umehluko wombala uba mkhulu. Iyunithi yalokhu kubekezelelana kombala yi-SDCM,. Ukubekezelelana kwe-Chromatic kunquma umehluko embala wokukhanya weqoqo lezibani. Ububanzi bokubekezelelana kombala buvame ukuboniswa kugrafu njenge-ellipse kunokuba yindilinga. Imishini yobuchwepheshe ejwayelekile inezingqimba ezihlanganisayo ukukala idatha ethile, kanti ezinye izimboni zokupakisha ze-LED kanye nezimboni zokukhanyisa zinemishini yobuchwepheshe ehlobene.

Sinomshini wethu wokuhlola esikhungweni sokuthengisa kanye nasefektri, isampula ngayinye kanye nengxenye yokuqala yokukhiqiza (kufaka phakathi i-COB LED STRIP, i-NEON FLEX, i-SMD LED STRIP kanye ne-RGB LED STRIP) kuzohlolwa, futhi ukukhiqizwa ngobuningi kuzokwenziwa kuphela ngemva kokuphumelela ukuhlolwa. Siphinde sihlanganise ubuhlalu besibani ngokwethu, obungalawulwa kahle yibhodlela lokukhanya kwe-LED strip.

Ngenxa yokuguquguquka kombala okhiqizwa ama-LED amhlophe, indlela elula yokulinganisa ubukhulu bomehluko wombala ngaphakathi kweqoqo lama-LED inani lezinyathelo ze-SDCM (MacAdam) ellipses ama-LED awela kuzo. Uma ama-LED wonke ewela ngaphakathi kwe-SDCM eyodwa (noma "i-ellipse yesinyathelo esisodwa se-MacAdam"), abantu abaningi bazohluleka ukubona noma yimuphi umehluko ngombala. Uma ukushintshashintsha kombala kukwenza ukuthi ukushintshashintsha kwe-chromaticity kudlulele endaweni enkulu kabili (2 SDCM noma i-ellipse yesinyathelo ezimbili ye-MacAdam), uzoqala ukubona umehluko wombala. I-ellipse yesinyathelo ezimbili ye-MacAdam ingcono kune-zone yesinyathelo ezintathu, njalo njalo.

Kodwa-ke, kunezici eziningi ezithinta ukubekezelelana kombala, njengezizathu ze-chip ye-LED, isizathu sesilinganiso se-phosphor powder, isizathu sokushintsha komshini wokushayela, kanye nesakhiwo sesibani kuzothinta nokushisa kombala. Isizathu sokwehla kokukhanya kanye nokuguga okusheshayo komthombo wokukhanya, ukukhukhuleka kokushisa kombala kwe-LED nakho kuzokwenzeka ngesikhathi senqubo yokukhanyisa, ngakho-ke ezinye izibani manje zicabangela izinga lokushisa lombala futhi zilinganise izinga lokushisa lombala esimweni sokukhanyisa ngesikhathi sangempela. Izindinganiso zokubekezelelana kombala zifaka amazinga aseNyakatho Melika, amazinga e-IEC, amazinga aseYurophu njalo njalo. Imfuneko yethu evamile yokubekezelelana kombala we-LED yi-5SDCM. Ngaphakathi kwalolu hlu, amehlo ethu ahlukanisa ngokuyisisekelo ukuphambuka kwe-chromatic.
