Yintoni i-colour binning kunye ne-SDMC?

Ukunyamezelana kombala: Yingcamango enxulumene kakhulu nobushushu bombala. Le ngcamango yacetywayo ekuqaleni yiKodak kushishino, iBritish yiStandard Deviation of Color Matching, ebizwa ngokuba yiSDCM. Ngumahluko phakathi kwexabiso elibalwe yikhompyutha kunye nexabiso eliqhelekileyo lomthombo wokukhanya ekujoliswe kuwo. Oko kukuthi, ukunyamezelana kombala kunesalathiso esithile kumthombo wokukhanya ekujoliswe kuwo.

Izixhobo ze-photochromic zihlalutya uluhlu lobushushu bombala womthombo wokukhanya olinganisiweyo, zize emva koko zigqibe ixabiso lobushushu bombala oqhelekileyo we-spectral. Xa ubushushu bombala bufana, bugqiba ixabiso le-coordinate xy yombala kunye nomahluko phakathi kwayo nomthombo wokukhanya oqhelekileyo. Okukhona ukunyamezela kombala kukhulu, kokukhona umahluko wombala umkhulu. Iyunithi yolu kunyamezela kombala yi-SDCM,. Ukunyamezelana kwe-Chromatic kumisela umahluko kumbala wokukhanya weqela lezibane. Uluhlu lokunyamezelana kombala ludla ngokuboniswa kwigrafu njenge-ellipse endaweni yesangqa. Izixhobo zobungcali ngokubanzi zineendawo ezidibeneyo zokulinganisa idatha ethile, kwaye ezinye iifektri zokupakisha ze-LED kunye neefektri zokukhanyisa zinezixhobo zobungcali ezinxulumeneyo.

Sinomatshini wethu wovavanyo kwiziko lokuthengisa nakwifektri, isampuli nganye kunye nenxalenye yokuqala yemveliso (kubandakanya i-COB LED STRIP, i-NEON FLEX, i-SMD LED STRIP kunye ne-RGB LED STRIP) ziya kuvavanywa, kwaye imveliso enkulu iya kwenziwa kuphela emva kokuphumelela uvavanyo. Sikwafaka iintsimbi zezibane ngokwethu, ezinokulawulwa kakuhle yibhini yesibane se-LED strip.

Ngenxa yokuguquguquka kombala oveliswa zii-LED ezimhlophe, indlela elula yokulinganisa ubungakanani bomahluko wombala ngaphakathi kweqela lee-LED linani lamanyathelo e-ellipses e-SDCM (MacAdam) apho ii-LED ziwela khona. Ukuba zonke ii-LED ziwela ngaphakathi kwe-SDCM e-1 (okanye "i-ellipse ye-MacAdam yenyathelo eli-1"), uninzi lwabantu aluyi kubona naluphi na umahluko kumbala. Ukuba umahluko wombala unjalo kangangokuba umahluko kwi-chromaticity udlulela kwindawo enkulu kabini (ii-SDCM ezi-2 okanye i-ellipse ye-MacAdam yenyathelo eli-2), uya kuqala ukubona umahluko wombala. I-ellipse ye-MacAdam yenyathelo eli-2 ingcono kune-3-step zone, njalo njalo.

Nangona kunjalo, kukho izinto ezininzi ezichaphazela ukunyamezelana kombala, njengezizathu ze-chip ye-LED, isizathu somlinganiselo we-phosphor powder, isizathu sokutshintsha komsinga wokuqhuba, kunye nolwakhiwo lwesibane kuya kuchaphazela ubushushu bombala. Isizathu sokwehla kokukhanya kunye nokuguga okukhawulezileyo komthombo wokukhanya, ukushukuma kobushushu bombala be-LED kuya kwenzeka ngexesha lenkqubo yokukhanyisa, ngoko ke ezinye izibane ngoku ziqwalasela ubushushu bombala kwaye zilinganise ubushushu bombala kwimeko yokukhanyisa ngexesha langempela. Imigangatho yokunyamezelana kombala ibandakanya imigangatho yaseMntla Melika, imigangatho ye-IEC, imigangatho yaseYurophu njalo njalo. Imfuneko yethu ngokubanzi yokunyamezelana kombala we-LED yi-5SDCM. Ngaphakathi kolu luhlu, amehlo ethu ngokusisiseko ahlula ukuguquguquka kwe-chromatic.
