CCTIsobanura ubushyuhe bw'amabara bufitanye isano (akenshi bugabanywa n'ubushyuhe bw'amabara). Isobanura ibara, ntabwo ari urumuri rw'isoko, kandi ipimwa muri Kelvins (K) aho gupimwa muri dogere Kelvin (°K).

Buri bwoko bw'urumuri rwera rufite ibara ryarwo, rugera ahantu runaka ku ishusho y'umuhondo kuva ku ibara ry'ubururu. CCT nkeya iri ku mpera y'ibara ry'umuhondo, mu gihe CCT nini iri ku mpera y'ubururu n'umweru.

Ku bijyanye n'ibyo, amatara asanzwe akoresha incandescent ashobora kuba agera kuri 3000K, mu gihe amwe mu mamodoka mashya afite amatara yera ya Xenon angana na 6000K.

Ku ruhande rwo hasi, amatara "ashyushye", nk'amatara ya buji cyangwa amatara ashyushye, atuma umuntu yumva atuje kandi amerewe neza. Ku ruhande rwo hejuru, urumuri "rukonje" ruratuma umuntu yumva amerewe neza kandi arushaho kumererwa neza, nk'ikirere cy'ubururu gisa neza. Ubushyuhe bw'amabara butuma habaho ikirere, bukagira ingaruka ku byiyumvo by'abantu, kandi bushobora guhindura uburyo amaso yacu abona ibintu birambuye.

garagaza ubushyuhe bw'ibara

Ubushyuhe bw'ibarabigomba kugaragazwa mu bipimo by'ubushyuhe bwa Kelvin (K). Dukoresha Kelvin ku rubuga rwacu no ku mpapuro zigaragaza ubushyuhe kuko ari uburyo bwiza bwo gushyira ku rutonde ubushyuhe bw'amabara.

Nubwo amagambo nka umweru ushyushye, umweru karemano, n'umurango akunze gukoreshwa mu gusobanura ubushyuhe bw'amabara, ubu buryo bushobora guteza ibibazo kuko nta gisobanuro cyuzuye cy'agaciro ka CCT (K) kabyo.

Urugero, ijambo "umweru ushyushye" rishobora gukoreshwa na bamwe mu gusobanura urumuri rwa LED rwa 2700K, ariko iri jambo rishobora no gukoreshwa n'abandi mu gusobanura urumuri rwa 4000K!

Ibisobanuro by'ubushyuhe bw'amabara bizwi cyane n'ibigereranyo byabyo. Agaciro ka K:

Umweru ushyushye cyane 2700K

Ibara ry'umweru rishyushye 3000K

Ibara ry'umweru ritagira aho ribogamiye 4000K

Icyera Gikonje 5000K

Umucyo w'amanywa 6000K
