Ma fahantay "Lumen" in laambaddu tahay inay ogaato?

IibsigabannaanmadaxnallaahiyokaamulLaydhku badanaa waxay arkaan ereyga "Lumen", ma fahantay?

Lumens = wax soo saarka fudud. Marka loo eego sahlan, lambarada (LM-ka ee LM) waa cabir wadarta tirada iftiinka muuqata (in isha bini-aadamka ah) laambad ama ilo iftiin ah.

Ugu badanbannaanka dibeddakaamuliftiin, madaxa ama tooshKulamada waa nalalka, kuwaas oo adeegsanaya tamar yar sidaa darteedna waxay leeyihiin qiimeyn aad u yar oo watt ah. Tani waxay ka dhigaysaa watts-ka aan u adeegsan jirnay in lagu cabiro iftiinka nalka nalka iftiinka ee aan la dabaqi karin, sidaa darteed soosaarayaasha ayaa u wareegaya Lummens.

Lumen, unug jireed oo sharraxaya kuleylka iftiinka, waxaa lagu qiimeeyaa "lm", oo gaagaaban "lameen". Qiimaha sare ee qiimaha yar, nalka iftiinka. Haddii aadan hubin lambarrada lumbeen, shaxdan ee ka-gudubka ah ee nalalka hogaaminaya ayaa laga yaabaa inay ku siiyaan fikrad. Taasi waa, markii aad rabto in la helo iyada oo lagu gaari karo saamaynta laambad 100W iyo kuwa la soo koobi karo, dooro 16-20W oo hogaamiya oo waxaad heli doontaa isla dhalaal isku mid ah.

Dibedda, iyadoo loo eegayo noocyo kala duwan oo nashaadaad ah guud ahaan waxay u baahan yihiin heerar lumen oo kala duwan, waxaad ka fiirsan kartaa isbeddelada habeenkii, oo ah 400 ~

Ka taxaddar markaad isticmaaleysoNalalka bannaanka(Gaar ahaan kuwa leh LUMENS-da sare), ha ku tilmaamin indhaha dadka. Iftiinka aad u wanaagsan ayaa sababi karta waxyeelo indhaha dadka.
