Njengohlobo olusha lomthombo wokukhanyisa, i-LED (I-Light Emitting Diode) inezinzuzo zokusebenza kahle kwamandla, impilo ende, nemibala egqamile, futhi ithandwa kakhulu phakathi kwabantu. Kodwa-ke, ngenxa yezimpawu ezibonakalayo ze-LED ngokwayo kanye nenqubo yokukhiqiza, ukushuba kokukhanya kwemibala ehlukene kuzohluka lapho umthombo wokukhanya we-LED ukhipha ukukhanya, okuzothinta ukukhiqizwa kombala wemikhiqizo yokukhanyisa kwe-LED. Ukuze kuxazululwe le nkinga, kwavela i-CRI (Colour Rendering Index, ukuhumusha kwesiShayina “inkomba yokubuyisela umbala”).
Inkomba ye-CRI ingenye yezinkomba ezibalulekile zokulinganisa ukukhiqizwa kombala kwemikhiqizo yokukhanyisa kwe-LED. Kalula nje, inkomba ye-CRI iyinani lokuhlola elihlobene elitholwe ngokuqhathanisa ukukhiqizwa kombala komthombo wokukhanya ngaphansi kwezimo zokukhanya kanye nalokho komthombo wokukhanya wemvelo ngaphansi kwezimo ezifanayo. Ibanga lenani lenkomba ye-CRI ngu-0-100, inani eliphakeme kakhulu, ngcono ukuvela kabusha kombala komthombo wokukhanya we-LED, futhi umphumela wokukhiqiza umbala usondele kakhulu ekukhanyeni kwemvelo.
Kuzinhlelo zokusebenza ezingokoqobo, ibanga lenani lenkomba ye-CRI alilingani ngokuphelele nekhwalithi yokukhiqiza kabusha kombala. Ngokuqondile, imikhiqizo yokukhanyisa i-LED enenkomba ye-CRI engaphezu kuka-80 isingakwazi ukuhlangabezana nezidingo zabantu abaningi. Kwezinye izikhathi ezikhethekile, njengemibukiso yobuciko, imisebenzi yezokwelapha nezinye izikhathi ezidinga ukukhiqizwa kombala okunembayo okuphezulu, kuyadingeka ukukhetha izibani ze-LED ezinenkomba ye-CRI ephakeme.
Kumele kuqashelwe ukuthi inkomba ye-CRI ayiyona inkomba kuphela yokukala ukukhiqizwa kombala wemikhiqizo yokukhanyisa i-LED. Ngokuthuthukiswa okuqhubekayo kobuchwepheshe be-LED, ezinye izinkomba ezintsha zenziwa kancane kancane, njenge-GAI (I-Gamut Area Index, ukuhumusha kwesiShayina "i-color gamut area index") njalonjalo.
Ngamafuphi, inkomba ye-CRI ingenye yezinkomba ezibalulekile zokulinganisa ukukhiqizwa kombala wemikhiqizo yokukhanyisa kwe-LED, futhi inenani eliphakeme elisebenzayo. Ngokuthuthuka okuqhubekayo kobuchwepheshe, kukholakala ukuthi ukukhiqizwa kombala kwemikhiqizo yokukhanyisa kwe-LED kuzoba ngcono futhi kube ngcono esikhathini esizayo, kudala indawo yokukhanya ekhululekile nemvelo yabantu.
