Kumva CRI na lumens

Kimwe nibindi bice byinshi bya siyansi yamabara, tugomba gusubira kumurongo wo gukwirakwiza imbaraga zumucyo.
CRI ibarwa mugusuzuma urwego rwumucyo hanyuma ukigana kandi ukagereranya urwego rwerekana ibizamini byamabara.
CRI ibara amanywa cyangwa umubiri wumukara SPD, CRI yo hejuru rero yerekana ko urumuri rwumucyo rusa numucyo usanzwe (CCTs) cyangwa urumuri rwa halogene / rwinshi (CCT yo hepfo).

Umucyo w'isoko yumucyo usobanurwa nibisohoka byacyo, bipimirwa muri lumens. Umucyo, kurundi ruhande, rwose ni inyubako yumuntu! Igenwa nuburebure bwumurongo amaso yacu yunvikana cyane nubunini bwingufu zumucyo ziboneka murubwo burebure. Twise ultraviolet na infragre yumurambararo "utagaragara" (ni ukuvuga, nta mucyo) kubera ko amaso yacu adashobora "gutora" ubwo burebure nkububonwa bwumucyo, tutitaye kungufu zingana muri zo.
Imikorere ya Luminosity

Abahanga mu ntangiriro z'ikinyejana cya makumyabiri bakoze uburyo bwa sisitemu yo kureba abantu kugira ngo basobanukirwe neza uburyo ibintu byerekana umucyo bikora, kandi ihame shingiro ryihishe inyuma ni umurimo wo kumurika, usobanura isano iri hagati yuburebure bwumuriro no kumva umucyo.

Umuhondo w'umuhondo ugereranya imikorere isanzwe ya fotokopi (hejuru)
Umucyo wumucyo uri hejuru ya 545-555 nm, uhuye nicyatsi kibisi-icyatsi kibisi, kandi kigabanuka vuba kumurongo muremure kandi wo hasi. Icy'ingenzi, urumuri ruri hasi cyane kurenza 650 nm, bihuye nuburebure bwamabara atukura.
Ibi bivuze ko uburebure bwamabara atukura, kimwe nubururu bwijimye nubururu bwa violet, ntibishobora gutuma ibintu bigaragara neza. Icyatsi kibisi n'umuhondo, kurundi ruhande, nibyiza cyane kugaragara neza. Ibi birashobora gusobanura impamvu imyambaro yumutekano igaragara cyane hamwe nabamurika cyane bakoresha amabara yumuhondo / icyatsi kugirango bagere kumucyo ugereranije.
Hanyuma, iyo tugereranije imikorere yumucyo na spekiteri yumucyo wumunsi, byakagombye kumvikana impamvu CRI ndende, cyane cyane R9 kumutuku, ivuguruzanya numucyo. Ikintu cyuzuye, cyagutse hafi ya cyose ni ingirakamaro mugihe ukurikirana CRI ndende, ariko icyerekezo kigufi cyibanze kumurongo wicyatsi kibisi-umuhondo cyumuhondo kizagira akamaro cyane mugihe gikurikiranye neza.

Ubwiza bwamabara na CRI hafi ya byose bimanikwa mubyambere mugukurikirana ingufu zingirakamaro kubwiyi mpamvu. Kugirango bibe byiza, bimwe mubisabwa, nkakumurika hanze, irashobora gushimangira cyane kubikorwa kuruta gutanga amabara. Gusobanukirwa no gushima ibya fiziki birimo, kurundi ruhande, birashobora kuba ingirakamaro mugufata icyemezo kiboneye mumashanyarazi.
