Ma fahantay "lumen" ay tahay in laambad ay ogaato?

Lumens = Wax soo saarka Iftiinka. Si fudud, Lumens (oo lagu tilmaamo lm) waa cabbir wadarta guud ee iftiinka la arki karo (isha aadanaha) ee ka imanaya laambad ama ilo iftiin.

Inta ugu badanbannaanka caadiga ahteendhoiftiin, laambad ama tooshQalabka korontada ku shaqeeya waa nalalka LED-ka, kuwaas oo isticmaala tamar yar sidaas darteedna leh heer watt oo hooseeya. Tani waxay ka dhigaysaa watt-kii aan u adeegsan jirnay cabbiraadda dhalaalka nalka inuu sii jiri waayo, sidaa darteed soosaarayaashu waxay u wareegayaan lumens.

Lumen, oo ah cutub jireed oo qeexaya qulqulka iftiinka, waxaa lagu qiimeeyaa "lm", oo loo soo gaabiyo "lumen". Qiimaha lumen-ka oo sarreeya, ayaa nalka iftiimaya. Haddii aadan hubin tirooyinka lumen-ka, jaantuskan nalalka LED-ka ee dhalaalaya ayaa laga yaabaa inuu ku siiyo tilmaan. Taasi waa, marka aad rabto LED gaari kara saameynta laambad 100W ah, dooro LED 16-20W ah waxaadna heli doontaa qiyaastii iftiin isku mid ah.

Dibadda, iyadoo loo eegayo noocyada kala duwan ee hawlaha guud ahaan waxay u baahan yihiin heerar kala duwan oo lumen ah, waxaad tixraaci kartaa xogta soo socota: xerada habeenkii: qiyaastii 100 lumen socod habeenimo ah, isgoys (tixgelinta isbeddellada cimilada sida roobka iyo ceeryaamo): 200 ~ 500 lumen oo ku saabsan orodka waddooyinka ama tartamada kale ee habeenkii: 500 ~ 1000 lumen raadinta iyo samatabbixinta habeenimo xirfadeed: in ka badan 1000 lumen

Ka taxaddar markaad isticmaaleysonalalka hore ee bannaanka(gaar ahaan kuwa leh lumen sare), ha u jeedin indhaha aadanaha. Iftiin aad u dhalaalaya wuxuu waxyeello u geysan karaa indhaha aadanaha.
