Kodi mukumvetsa "lumen" yomwe nyali iyenera kudziwa?

Mu kugula kwakunjamutunyalendikumanga msasanyali nthawi zambiri amawona mawu akuti "lumen", kodi mukumvetsa?

Lumens = Kutulutsa Kuwala.M'mawu osavuta, Lumens (otchulidwa ndi lm) ndi muyeso wa kuchuluka kwa kuwala kowonekera (kumaso a munthu) kuchokera ku nyali kapena gwero la kuwala.

Kwambiriwamba panjakumanga msasakuwala, nyali yakumutu kapena tochizopangira ndi nyali za LED, zomwe zimagwiritsa ntchito mphamvu zochepa motero zimakhala ndi ma watt otsika.Izi zimapangitsa kuti ma watt omwe timagwiritsa ntchito kuyeza kuwala kwa babu sakugwiranso ntchito, kotero opanga akusintha ma lumens.

Lumen, gawo la thupi lomwe limafotokoza kutuluka kwa kuwala, limayikidwa ndi "lm", mwachidule "lumen".Kukwera kwa mtengo wa lumen, babu yowala kwambiri.Ngati simukudziwa za manambala a lumen, tchati ichi cha nyali za LED zitha kukupatsani chidziwitso.Ndiye kuti, mukafuna LED yomwe ingathe kukwaniritsa nyali ya 100W incandescent, sankhani 16-20W LED ndipo mudzapeza kuwala komweko.

Kunja, malinga ndi mitundu yosiyanasiyana ya zochitika zomwe nthawi zambiri zimafunikira milingo yosiyanasiyana ya lumen, mutha kuloza izi: kumisasa usiku: pafupifupi 100 lumen yoyenda usiku, kuwoloka (poganizira kusintha kwanyengo monga mvula ndi chifunga) : 200 ~ 500 lumen pafupifupi mayendedwe othamanga kapena mipikisano ina yausiku: 500 ~ 1000 lumen kufufuza ndi kupulumutsa usiku: kuposa 1000 lumen

Samalani mukamagwiritsa ntchitonyali zapanja(makamaka omwe ali ndi lumens yapamwamba), musawaloze pamaso pa anthu.Kuwala kwambiri kumatha kuwononga maso a anthu.
