Urumva "lumen" itara rigomba kumenya?

Mu kugurahanzeUmutweamataranagukambikaAmatara akunze kubona ijambo "Lumen", urabyumva?

Lumens = ibisohoka byoroheje. Mu magambo yoroshye, lumens (yerekanwe na LM) ni igipimo cyumucyo wose ugaragara (kumutwe wumuntu) uhereye kumatara cyangwa isoko yumucyo.

ByinshiHanze Hanzegukambikaurumuri, umutwe cyangwa itaraImikino iyobowe amatara, akoresha imbaraga nke bityo akagira umwanya wo hasi. Ibi bituma watts twakundaga gupima urumuri rwinshi ntirukoreshwa, bityo abakora barimo guhinduka kuri lumens.

Lumen, igice cyumubiri gisobanura flux yumucyo, gishyirwa kuri "LM", ngufi kuri "lumen". Agaciro ka LUMEN, urumuri rwinshi. Niba utazi neza umubare wa LINMEN, iyi mbonerahamwe ya incandentcent kumatara yayoboye irashobora kuguha ibimenyetso. Ni ukuvuga, mugihe ushaka kuyoborwa bishobora kugera ku ngaruka za 100w itara rya 100w, hitamo 16-20w iyoboye kandi uzabona umucyo umwe.

Mu hanze, ukurikije ubwoko butandukanye bwibikorwa muri rusange bakeneye urwego rusanzwe rwa lumen, urashobora kwerekeza kumakuru akurikira: Gutembera mu majwi ya saa sita: 500 lumen lumen gushakisha nijoro gushakisha no gutabara.

Witonde iyo ukoreshejeAmatara yo hanze(cyane cyane abafite lumens bo hejuru), ntukabereke mumaso yabantu. Umucyo mwinshi urashobora kwangiza amaso yabantu.
