I-SDCM yokubekezelela umbala ibhekisela emehlukweni wombala phakathi kwemishayo ehlukene ekhishwa umthombo wokukhanya wombala ofanayo ngaphakathi kwebanga lombala elibonwa iso lomuntu, ngokuvamile elivezwa amanani ezinombolo, okwaziwa nangokuthi umehluko wombala. I-SDCM yokubekezelela umbala ingenye yezinkomba ezibalulekile zokulinganisa ukufana kombala wemikhiqizo yokukhanyisa kwe-LED. Kuzinhlelo zokusebenza zokukhanyisa kwe-LED, ubukhulu be-SDCM yokubekezelela umbala buthinta ngokuqondile ikhwalithi nokuzinza komphumela wokukhanyisa.
Indlela yokubala ye-SDCM yokubekezelela umbala iwukuguqula umehluko wokuxhumanisa phakathi komthombo wokukhanya ohloliwe kanye nomthombo wokukhanya ojwayelekile ube inani le-SDCM ngokuya ngomdwebo we-CIE 1931 chromaticity. Uma inani le-SDCM lincane, kuba ngcono ukuvumelana kombala, kanye nomehluko wombala omkhulu. Ngaphansi kwezimo ezijwayelekile, imikhiqizo enamanani e-SDCM phakathi koku-3 ithathwa njengemikhiqizo enombala omuhle, kuyilapho leyo engaphezu kuka-3 idinga ukuthuthukiswa.
Kuzinhlelo zokusebenza zokukhanyisa kwe-LED, ukuvumelana kombala kunomthelela obalulekile ekuzinzeni nasekududuzeni komphumela wokukhanyisa. Uma ukungaguquguquki kombala kwemikhiqizo yokukhanyisa kwe-LED kungalungile, umbala wezindawo ezihlukene esigcawini esifanayo uzohluka kakhulu, kuthinte okuhlangenwe nakho okubonakalayo komsebenzisi. Ngesikhathi esifanayo, imikhiqizo enombala obuthakathaka ingase ibangele izinkinga ezifana nokukhathala okubonakalayo kanye nokuhlanekezela kombala.
Ukuze uthuthukise ukuhambisana kombala wemikhiqizo yokukhanyisa kwe-LED, kuyadingeka ukuqala kusuka ezicini eziningi. Okokuqala, ikhwalithi ye-chip ye-LED idinga ukulawulwa ngokuqinile ukuze kuqinisekiswe ukuhambisana kombala kwe-chip ye-LED. Okwesibili, ukulawulwa kwekhwalithi okuqinile kuyadingeka emikhiqizweni yokukhanyisa kwe-LED ukuze kuqinisekiswe ukuthi ukuhambisana kombala komkhiqizo ngamunye kuyefana. Okokugcina, isistimu yokukhanyisa kwe-LED idinga ukulungiswa futhi ithuthukiswe ukuze kuqinisekiswe ukufana kombala phakathi kwemithombo yokukhanya ehlukahlukene.
Ngamafuphi, ukubekezelelana kombala i-SDCM ingenye yezinkomba ezibalulekile zokulinganisa ukuhambisana kombala wemikhiqizo yokukhanyisa i-LED, edlala indima ebalulekile ekuthuthukiseni ikhwalithi nokuzinza komphumela wokukhanyisa wemikhiqizo yokukhanyisa i-LED. Ukuze uthuthukise ukungaguquguquki kombala wemikhiqizo yokukhanyisa kwe-LED, kuyadingeka ukuthi kuqalwe ezicini eziningi ukuze kuqinisekiswe ukuthi ikhwalithi yama-chips e-LED, ikhwalithi yemikhiqizo yokukhanyisa kwe-LED kanye nokulungiswa kwamaphutha kwezinhlelo zokukhanyisa ze-LED kuhlangabezana nezinga.
