Kodi mukumvetsa "lumination" yomwe nyali iyenera kudziwa?

Mu kugula kwapanjamutunyalindikumanga msasaNyali nthawi zambiri zimawona mawu oti "lumen", kodi mukumvetsa?

Ma Lumens = Kuwala Kotuluka. Mwachidule, Ma Lumens (omwe amatchulidwa ndi lm) ndi muyeso wa kuchuluka konse kwa kuwala kooneka (kwa diso la munthu) kuchokera ku nyali kapena gwero la kuwala.

Kwambiriwamba panjakumanga msasakuwala, nyali yakutsogolo kapena tochiZopangira magetsi ndi magetsi a LED, omwe amagwiritsa ntchito mphamvu zochepa motero amakhala ndi mphamvu zochepa za watt. Izi zimapangitsa kuti ma watt omwe tinkagwiritsa ntchito poyesa kuwala kwa babu asakhalenso ntchito, kotero opanga magetsi akusintha kupita ku ma lumens.

Lumen, gawo lenileni lofotokoza kayendedwe ka kuwala, limayesedwa ndi "lm", chidule cha "lumen". Lumen ikakwera, babu limakhala lowala kwambiri. Ngati simukudziwa bwino za manambala a lumen, tchati ichi cha magetsi a incandescent ndi LED chingakupatseni chidziwitso. Ndiye kuti, mukafuna LED yomwe ingathe kukwaniritsa mphamvu ya nyali ya incandescent ya 100W, sankhani LED ya 16-20W ndipo mudzapeza kuwala kofanana.

Panja, malinga ndi mitundu yosiyanasiyana ya zochita nthawi zambiri pamafunika milingo yosiyanasiyana ya lumen, mutha kuwona izi: kukampala usiku: pafupifupi ma lumen 100 usiku, kukwera mapiri, kuwoloka (poganizira kusintha kwa nyengo monga mvula ndi chifunga): 200~500 lumen yokhudza kuthamanga panjira kapena mipikisano ina yausiku: 500~1000 lumen akatswiri kusaka ndi kupulumutsa usiku: ma lumen oposa 1000

Samalani mukamagwiritsa ntchitonyali zakunja(makamaka omwe ali ndi ma lumens ambiri), musawaloze m'maso mwa anthu. Kuwala kwambiri kungayambitse kuwonongeka kwa maso a anthu.
