Yintoni i-color binning kunye ne-SDMC?

Ukunyamezelana kombala: Yingcamango esondelelene nobushushu bombala. Le ngcamango yacetywa kuqala nguKodak kwishishini, iBritish yi-Standard Deviation of Color Matching, ebizwa ngokuba yi-SDCM. Ngumahluko phakathi kwexabiso lekhompyutha elibalwe kunye nexabiso eliqhelekileyo lomthombo wokukhanya ojoliswe kuyo. Oko kukuthi, ukunyamezela kombala kunesalathiso esithile kumthombo wokukhanya ojoliswe kuyo.

Isixhobo se-photochromic sihlalutya uluhlu lobushushu bombala womthombo wokukhanya olinganisiweyo, kwaye emva koko simisela ixabiso lobushushu bombala obonakalayo. Xa ubushushu bombala bufana, bumisela ixabiso lolungelelwaniso lombala xy kunye nomahluko phakathi kwayo kunye nomthombo wokukhanya osemgangathweni. Okukhona ukunyamezelana kombala mkhulu, kokukhona umahluko wombala. Iyunithi yokunyamezela kombala yi-SDCM,. Ukunyamezela kweChromatic kugqiba umahluko kumbala okhanyayo webhetshi yezibane. Uluhlu lonyamezelo lombala ludla ngokuboniswa kwigrafu njenge-ellipse kunesangqa. Izixhobo zobuchwephesha ngokubanzi zinamacandelo okudibanisa ukulinganisa idatha ethile, kwaye ezinye iifektri zokupakisha ze-LED kunye neefektri zokukhanyisa zinezixhobo ezihambelanayo.

Sinomatshini wethu wokuvavanya kwiziko lokuthengisa kunye nefektri, isampuli nganye kunye nenxalenye yokuqala yemveliso (kubandakanya i-COB LED STRIP, NEON FLEX, SMD LED STRIP AND RGB LED STRIP) iya kuvavanywa, kwaye ukuveliswa kobuninzi kuya kwenziwa kuphela emva kokudlula. uvavanyo.Sikwafaka amaso isibane ngokwethu, esinokulawulwa kakuhle umgqomo wokukhanya komcu we-LED.

Ngenxa yokuguquguquka kombala oveliswa zizibane ezimhlophe ze-LED, i-metric efanelekileyo yokubonisa ubungakanani bomahluko wombala ngaphakathi kwebhetshi yee-LED linani le-SDCM (MacAdam) ellipses amanyathelo awela kuwo ii-LED. Ukuba ii-LED zonke ziwela ngaphakathi kwe-1 SDCM (okanye "i-1-step MacAdam ellipse"), abaninzi abantu baya kusilela ukubona nawuphi na umahluko kumbala. Ukuba ukwahluka kombala kwenze ukuba ukwahluka kwechromaticity kunwenwele kwindawo enkulu ngokuphindwe kabini (2 SDCM okanye inyathelo eli-2 le-MacAdam ellipse), uyakuqala ukubona umahluko wombala. I-2-step MacAdam ellipse ingcono kune-3-step zone, njalo njalo.

Nangona kunjalo, kukho izinto ezininzi ezichaphazela ukunyamezela kombala, njengezizathu ze-chip ye-LED, isizathu somlinganiselo we-phosphor powder, isizathu sokutshintsha kwangoku, kunye nokwakheka kwesibane kuya kuchaphazela ubushushu bombala. Isizathu sokuncipha kokukhanya kunye nokuguga okukhawulezileyo komthombo wokukhanya, ukukhanya kombala wokukhanya kwe-LED kuya kwenzeka ngexesha lenkqubo yokukhanyisa, ke ezinye izibane ngoku ziqwalasela ubushushu bombala kwaye zilinganise ubushushu bombala kwindawo yokukhanyisa ngokwenyani. ixesha. Imigangatho yokunyamezela umbala ibandakanya imigangatho yaseMntla Melika, imigangatho ye-IEC, imigangatho yaseYurophu kunye nokunye. Imfuno yethu ngokubanzi yokunyamezela umbala we-LED yi-5SDCM. Kolu luhlu, amehlo ethu ahlula ngokusisiseko ukuphambuka kwechromatic.
