LED yerekana amabara

Abantu benshi kandi benshi muguhitamo amatara kandiamatara, igitekerezo cyamabara yerekana indangagaciro muburyo bwo guhitamo.

Ukurikije ibisobanuro bya "Architectural Lighting Design Standard", guhindura amabara bivuga isoko yumucyo ugereranije nisoko risanzwe ryumucyo, isoko yumucyo irerekana ibiranga ibara ryikintu. Ibara ryerekana amabara ni igipimo cyerekana ibara ryerekana isoko yumucyo, bigaragazwa nkurwego rwo guhuza ibara ryikintu munsi yumucyo wapimwe hamwe nibara ryikintu munsi yumucyo usanzwe.

Komisiyo mpuzamahanga ishinzwe kumurika (CIE) yashyizeho ibipimo byerekana amabara y’izuba ku 100, kandi iteganya amabara 15 y’ibizamini, ikoresheje R1 ~ R15 kugira ngo yerekane icyerekezo cyerekana aya mabara 15. Irashobora kwerekana neza ibara ryumwimerere ryibikoresho bikeneye gukoresha ibara ryinshi ryerekana indangagaciro (Ra) yumucyo utanga urumuri, agaciro kayo kegereye 100, gutanga amabara meza.

Ibara rusange ryerekana amabara, fata R1 ~ R8 ubwoko bwibara risanzwe ryerekana ibara ryerekana agaciro kagereranijwe, byanditswe nka Ra, biranga urumuri rutanga amabara. Ibara ryihariye ryerekana amabara yatoranijwe R9 ~ R15 ubwoko bwamabara asanzwe yerekana amabara yerekana amabara, yanditswe nka Ri.

Mubisanzwe tuvuga ko indangagaciro yo gutanga amabara mubisanzwe yerekeza kumurongo rusange wo gutanga amabara, ni ukuvuga agaciro ka Ra, ukurikije "Ibishushanyo mbonera byubatswe byubatswe," ibiteganijwe na Ra byibuze 80, ariko uhereye kumyuga yabigize umwuga reba, turashaka kandi gusuzuma ibara ryihariye ryerekana amabara.

Muri byo, ibara ryihariye ryerekana amabara R9 nubushobozi bwo kwerekana umutuku wuzuye, mugihe uguzeAmataranaamataradukeneye kwitondera byumwihariko agaciro ka R9. Iyo agaciro ka R9 kari hejuru, niko bigaragara neza ibara ryimbuto, indabyo, inyama, nibindi. Niba itara ritukura ryabuze mumucyo, bizagira ingaruka kumiterere yumucyo wibidukikije. Gusa rero iyo Ra na R9 bifite agaciro gakomeye icyarimwe, ibara ryinshi ryerekanaAmatarabirashobora kwizerwa.

Ukoresheje ibisobanuro byigihugu, iyo Ra ≥ 80 na R9 ≥ 0 yamatara, irashobora guhura cyane cyane nurutonde rwamabara asabwa mubikorwa bya buri munsi.

Twabibutsa ko benshiAmataraku isoko ubu igurishwa hamwe nagaciro ka R9, ugomba rero gusuzuma witonzeitaraguhitamo. Mubyongeyeho, niba ibara ryerekana ibipimo bisabwa ari byinshi, urashobora guhitamo amatara ya Ra ≥ 90, R9 ≥ 70.

Ibara rike cyane ryerekana amabara azagira ingaruka kumaso yacu kubintu byamenyekanye, bikavamo kugabanuka cyangwa kugabanuka mubushobozi bwo kumenya amabara, igihe kirekire mumabara mabi atanga isoko yumucyo, amaso yumuntu ya cone selile nayo azagabanuka, byoroshye kuzana umunaniro ugaragara, ndetse no gutera myopiya.

Kubwibyo, guhitamo amatara hamwe nurutonde rwamabara menshi arashobora kurinda amaso yacu kandi akatuzanira urumuri rwiza rwiza mugihe tunoza ibara ryibintu.
