Ukunyamezelana kombala I-SDCM ibhekiselele kumahluko kumbala phakathi kwemiqadi eyahlukeneyo ekhutshwa ngumthombo wokukhanya wombala ofanayo ngaphakathi koluhlu lombala oluqondwa ngeliso lomntu, ngokuqhelekileyo lubonakaliswa ngamaxabiso amanani, owaziwa ngokuba ngumahluko wombala. Ukunyamezela kombala i-SDCM yenye yezibonakaliso ezibalulekileyo zokulinganisa ukuhambelana kombala weemveliso zokukhanyisa i-LED. Kwizicelo zokukhanyisa i-LED, ubukhulu bokunyamezela kombala we-SDCM buchaphazela ngokuthe ngqo umgangatho kunye nokuzinza kwesiphumo sokukhanyisa.
Indlela yokubala yokunyamezela umbala we-SDCM kukuguqula umehluko wokulungelelanisa phakathi komthombo wokukhanya ovavanyiweyo kunye nomthombo wokukhanya osemgangathweni kwixabiso le-SDCM ngokwe-CIE 1931 chromaticity diagram. Ixabiso elincinci le-SDCM, ngcono ukuhambelana kombala, kwaye mkhulu umehluko wombala. Ngaphantsi kweemeko eziqhelekileyo, iimveliso ezinexabiso le-SDCM ngaphakathi kwe-3 zibhekwa njengemveliso ehambelana nombala omhle, ngelixa ezo zinkulu kune-3 zifuna ukuphuculwa ngakumbi.
Kwizicelo zokukhanyisa i-LED, ukuhambelana kombala kunempembelelo ebalulekileyo ekuzinzeni nasekuthuthuzeleni kwesiphumo sokukhanyisa. Ukuba ukuhambelana kombala weemveliso zokukhanya kwe-LED kubi, umbala weendawo ezahlukeneyo kwindawo efanayo uya kuba uhluke kakhulu, uchaphazela amava abonakalayo omsebenzisi. Kwangaxeshanye, iimveliso ezinombala ongaguqukiyo zinokubangela iingxaki ezifana nokudinwa okubonakalayo kunye nokuphazamiseka kombala.
Ukuze kuphuculwe ukuhambelana kombala weemveliso zokukhanyisa i-LED, kuyimfuneko ukuqala kwiinkalo ezininzi. Okokuqala, umgangatho we-chip ye-LED kufuneka ulawulwe ngokungqongqo ukuqinisekisa ukuhambelana kombala we-chip ye-LED. Okwesibini, ulawulo olungqongqo lwekhwalithi luyafuneka kwiimveliso zokukhanyisa i-LED ukuqinisekisa ukuba ukuhambelana kombala wemveliso nganye kuyafana. Ekugqibeleni, inkqubo yokukhanyisa i-LED kufuneka ihlaziywe kwaye ilungiswe ukuqinisekisa ukuhambelana kombala phakathi kwemithombo eyahlukeneyo yokukhanya.
Ngamafutshane, ukunyamezela kombala i-SDCM yenye yezibonakaliso ezibalulekileyo zokulinganisa ukuhambelana kombala weemveliso zokukhanyisa i-LED, edlala indima ebalulekileyo ekuphuculeni umgangatho kunye nokuzinza kwesiphumo sokukhanyisa kwemveliso yokukhanyisa i-LED. Ukuphucula ukuhambelana kombala weemveliso zokukhanyisa i-LED, kuyimfuneko ukuqala kwiinkalo ezininzi zokuqinisekisa ukuba umgangatho wee-chips ze-LED, umgangatho weemveliso zokukhanyisa i-LED kunye nokulungiswa kweenkqubo zokukhanyisa i-LED zihambelana nomgangatho.
