E le mofuta o mocha oa mohloli oa mabone, LED (Light Emitting Diode) e na le melemo ea matla a phahameng a matla, bophelo bo bolelele le mebala e khanyang, 'me e ntse e tsebahala haholoanyane har'a batho. Leha ho le joalo, ka lebaka la litšobotsi tsa 'mele tsa LED ka boeona le mokhoa oa ho etsa tlhahiso, matla a khanya ea mebala e fapaneng e tla fapana ha mohloli oa leseli la LED o hlahisa leseli, e leng se tla ama tlhahiso ea mebala ea lihlahisoa tsa mabone a LED. E le ho rarolla bothata bona, ho ile ha hlaha CRI (Colour Rendering Index, phetolelo ea Sechaena ke “color restoration index”).
Lenane la CRI ke e 'ngoe ea matšoao a bohlokoa a ho lekanya ho hlahisa mebala ea lihlahisoa tsa mabone a LED. Ka mantsoe a bonolo feela, index ea CRI ke tekanyo ea tlhahlobo e lekanyelitsoeng e fumanoeng ka ho bapisa tlhahiso ea mebala ea mohloli o khanyang tlas'a maemo a khanyang le a mohloli oa leseli la tlhaho tlas'a maemo a tšoanang. Phaello ea boleng ba index ea CRI ke 0-100, boleng bo phahameng, ho hlahisa mebala e ntle ea mohloli oa leseli la LED, 'me phello ea ho hlahisa mebala e haufi le leseli la tlhaho.
Lits'ebetsong tse sebetsang, palo ea boleng ba index ea CRI ha e lekane ka ho feletseng le boleng ba ho hlahisa mebala. Ka ho khetheha, lihlahisoa tsa mabone a LED tse nang le index ea CRI ka holimo ho 80 li ka se li ntse li finyella litlhoko tsa batho ba bangata. Liketsahalong tse ling tse khethehileng, tse kang lipontšo tsa bonono, ts'ebetso ea bongaka le liketsahalo tse ling tse hlokang ho hlahisa mebala e nepahetseng e phahameng, hoa hlokahala ho khetha mabone a LED a nang le index e phahameng ea CRI.
Hoa lokela ho hlokomeloa hore index ea CRI hase eona feela pontšo ea ho lekanya ho hlahisa mebala ea lihlahisoa tsa mabone a LED. Ka tsoelo-pele e tsoelang pele ea theknoloji ea LED, litsupa tse ling tse ncha li hlahisoa butle-butle, tse kang GAI (Gamut Area Index, phetolelo ea Sechaena ke "color gamut area index") joalo-joalo.
Ka bokhutšoanyane, index ea CRI ke e 'ngoe ea matšoao a bohlokoa a ho lekanya ho hlahisa mebala ea lihlahisoa tsa mabone a LED,' me e na le boleng bo phahameng bo sebetsang. Ka tsoelo-pele e tsoelang pele ea thekenoloji, ho lumeloa hore tlhahiso ea mebala ea lihlahisoa tsa mabone a LED e tla ntlafala le ho ntlafala nakong e tlang, e leng ho theha tikoloho e ntle le ea tlhaho bakeng sa batho.
