Nibintu bya psychologique bipima reaction yumucyo utangwa nigikoresho cyo kumurika mubidukikije byo mumaso imbere yijisho ryumuntu, kandi agaciro kayo gashobora kubarwa na CIE ihuriweho nigiciro cyagaciro ukurikije ibihe byagenwe.
Igishushanyo mbonera cy’amatara y’inganda n’imbonezamubano giteganya ko urumuri rutaziguye rw’amatara rusange yo mu ngo ari ntarengwa ukurikije umurongo ugabanya umurongo. Ubu buryo bwo kugabanya ni ubw'itara rimwe gusa, kandi ntirishobora kwerekana ingaruka zose zakozwe n'amatara yose yo mucyumba. Kubwibyo, CIE yashyize ahagaragara formulaire yo kubara agaciro kamwe kamwe (UGR) hashingiwe ku guhuza uburyo bwo kubara urumuri mu bihugu bitandukanye. Irakwiranye nuburyo rusange bwo kumurika icyumba cyoroshye cya cube. Amatara aringaniye aringaniye, kandi amatara arikubye kabiri hamwe no gukwirakwiza urumuri.
UGR yamatara ya LED yagabanijwe kuburyo bukurikira:
| Agaciro | Kumva |
| 25-28 | Kutihanganirwa |
| 22-25 | Ntibyoroshye |
| 19-22 | Urwego rwihanganira urumuri |
| 16-19 | Urwego rwemewe rwo kumurika, nkibiro hamwe n’ibyumba by’ishuri bisaba urumuri igihe kirekire, birakwiriye kururu rwego. |
| 13-16 | Ntiyumva igitangaza |
| 10-13 | Ntushobora kumva urumuri |
| ＜ 10 | Ibicuruzwa byumwuga byibyumba bikoreramo ibitaro |
Birumvikana, UGR ntabwo igicuruzwa kimwe gifite agaciro, kijyanye no gukoresha ibidukikije byo kumurika.
Kurugero, munsi yo kugaragariza icyumba, hejuru ya UGR. Ihame riroroshye cyane: uko itandukaniro riri hagati yumucyo w’ibidukikije n’umucyo wamatara, niko amaso atoroha. Niyo mpanvu ibidukikije bifite ubushobozi buke, nk'utubari cyangwa KTV, muri rusange ukoresha amatara ayobora n'amatara aho kumanika itara rinini imbere.
Muri iki gihe, ikibazo kiraje. Nka sosiyete yamurika, ntuzi ibidukikije abakiriya bawe bashiramo amatara, none ugomba gukora iki? Kubera ko bidashoboka kugenzura ibidukikije, noneho dukora UGR yibicuruzwa ubwabyo munsi ya 19/16/13/10, kugirango bitazangiza kwangiriza amaso yabakiriya.
Noneho nkumuguzi usanzwe nigute wahitamo amatara akwiye? Nibyoroshye cyane, urashobora guhitamo amatara ugr 19 hamwe na micro-yubatswe na anti-glare firime prism urupapuro.
Kuki UGR19? Kuberako UGR ifite ibiranga, ni ukuvuga ko byoroshye kugabanya kuva kuri 25 ukagera kuri 19, ariko biragoye cyane kugabanya kuva kuri 19 ukagera kuri 10. Tuvuge ko ukoresha imbaraga zikubye kabiri kuva 25 kugeza 19, ukava kuri 19 ukageza 16 Gicurasi igiciro inshuro 5, kandi igiciro kizaba gihenze cyane. Niyo mpamvu nsaba UGR19 nkuguhitamo kugiciro cyiza.
