CRI yo Kumurika

Nubwoko bushya bwamatara, LED (Light Emitting Diode) ifite ibyiza byo gukoresha ingufu nyinshi, kuramba, namabara meza, kandi biramenyekana cyane mubantu. Nyamara, bitewe nibiranga umubiri wa LED ubwayo hamwe nuburyo bwo gukora, ubukana bwurumuri rwamabara atandukanye bizaba bitandukanye mugihe urumuri rwa LED rutanga urumuri, bizagira ingaruka kumyororokere yibara ryibicuruzwa bitanga amatara ya LED. Kugira ngo iki kibazo gikemuke, CRI (Indanganturo y'amabara, igishinwa ni “indangagaciro yo kugarura amabara”) yabayeho.
Indangantego ya CRI ni kimwe mu bipimo byingenzi bipima ibara ryororoka ryibicuruzwa bimurika LED. Muri make, indangagaciro ya CRI nigereranya ryagaciro ryagereranijwe ryabonetse mugereranya ibara ryororoka ryumucyo utanga urumuri hamwe nurumuri rusanzwe rusanzwe mubihe bimwe. Agaciro kerekana indangagaciro ya CRI ni 0-100, uko agaciro kangana, niko amabara meza yororoka yumucyo wa LED, kandi niko ingaruka zo kubyara amabara ari hafi kumucyo usanzwe.
Mubikorwa bifatika, agaciro kerekana indangagaciro ya CRI ntabwo ihwanye rwose nubwiza bwimyororokere. By'umwihariko, LED yamurika ibicuruzwa bifite indangagaciro ya CRI iri hejuru ya 80 irashobora guhuza ibyifuzo byabantu benshi. Mubihe bimwe bidasanzwe, nkimurikagurisha ryubuhanzi, ibikorwa byubuvuzi nibindi bihe bisaba kubyara amabara yuzuye neza, birakenewe guhitamo amatara ya LED afite indangagaciro ndende ya CRI.
Twabibutsa ko indangagaciro CRI atari cyo cyonyine cyerekana gupima ibara ry'ibicuruzwa biva mu mucyo. Hamwe niterambere ryiterambere rya tekinoroji ya LED, ibipimo bimwe na bimwe bishya bitangizwa buhoro buhoro, nka GAI (Indanganturo ya Gamut, Igishinwa ni "ibara rya gamut agace kerekana") nibindi.
Muri make, indangagaciro ya CRI ni kimwe mu bipimo by'ingenzi bipima ibara ryororoka ry'ibicuruzwa bimurika LED, kandi bifite agaciro gakomeye. Hamwe niterambere ryiterambere ryiterambere ryikoranabuhanga, byizerwa ko ibara ryibara ryibicuruzwa byamatara ya LED bizagenda neza kandi byiza mugihe kizaza, bizane ahantu heza kandi hameze amatara kubantu.
