Kuki ukeneye igikwiye igitereko yo gukambika, amatara aroroshye kandi yoroheje, kandi ni ngombwa mugutembera nijoro, gutegura ibikoresho nibindi bihe.
1, urumuri: hejuru ya lumens, urumuri rwinshi!
Hanze, inshuro nyinshi "umucyo" ni ngombwa cyane.Kurugero, umurongo wijoro umusozi cyangwa ugashakisha ubuvumo, urumuri ntiruhagije rushobora gukandagirwa, kugwa, cyangwa kubura icyapa cyingenzi;"Amatara" azakugira "ibyago".Niba ukeneye kumurika, ugomba rero kwitondera ibipimo bya lumens.
(1) Gupima umucyo kuva lumens
Ubuzima, dukunze kuvuga urumuri "urumuri cyangwa rutamurika", mubyukuri, rwerekeza kumuri.Igice cya luminous flux ni lumen, kigaragaza ubushobozi bwumucyo bwumucyo.Niba ushaka kugura itara ryaka, dukwiye kwitondera lumens yibi bintu.Umucyo mwinshi uragufasha kubona neza ibidukikije imbere yawe.
(2) Ninini agaciro ka lumen, niko urumuri rwinshi.
Kuriamatara yo hanze na amatara, hari umubano mwiza hagati ya lumens nubucyo: uko agaciro ka lumen nini, niko flux yamurika, niko imbaraga zumucyo zituruka kumucyo.Kurugero, aItara rya lumen 1000 ni byiza kuruta a Amatara 300.
(3) Guhitamo umucyo
Kurwego rwo hejuru urumuri rwibicuruzwa narwo ruri hejuru, mugihe kugura bigomba guhuzwa hamwe nuburyo bwabo bwo gukoresha ibibera.Lumens 100 ihwanye n’umucyo wa buji 8, ibikorwa byambere byo gutembera hanze yo gukambika hanze kugirango uhitemo lumens 100 ~ 200 yibicuruzwa bihagije;ibicuruzwa byoroheje byihutirwa biri muri lumens 50 cyangwa irenga, ariko kandi birashobora guhaza ibikenewe kumurika.
Niba witabira siporo yo hanze ufite ibisabwa byinshi byo kumurika, urashobora gusuzuma ibicuruzwa 200 ~ 500.Niba hari byinshi bisabwa, nko kugenda byihuse (kwiruka kwambukiranya igihugu), cyangwa gukenera kumurika ahantu hanini, urashobora gusuzuma lumens 500 ~ 1000 y'ibicuruzwa.
Ibikenewe byumwuga, nko gushakisha ubutabazi, urashobora gutekereza ibirenze1000 lumens igitereko.Umucyo ntabwo bivuze kure, rimwe na rimwe ukeneye gushakisha no kwitegereza, rwose urizera ko urumuri ruri kure gato, hanyuma ukeneye ikindi kintu cyavuzwe hepfo.
