Ngaba uyayiqonda i-"lumen" ekufuneka isibane siyazi?

Ekuthengweni kwengaphandleintlokoizibanekwayeinkampuizibane zihlala zibona igama elithi "lumen", ngaba uyaliqonda?

IiLumens = IsiPhumo esiKhanyayo. Ngamagama alula, i-Lumens (echazwe ngu-lm) ngumlinganiselo wexabiso elipheleleyo lokukhanya okubonakalayo (kwiliso lomntu) ukusuka kwisibane okanye kumthombo wokukhanya.

Okuninzieqhelekileyo ngaphandleinkampuukukhanya, isibane okanye isibaneizinto ezilungiswayo zizibane ze-LED, ezisebenzisa amandla amancinci kwaye ngenxa yoko zine-watt-rating esezantsi. Oku kwenza ukuba iiwatts ebesizisebenzisa ukulinganisa ukuqaqamba kwebhalbhu yesibane zingasasebenzi, ke abavelisi batshintshela kwiilumens.

I-Lumen, iyunithi yomzimba echaza ukuhamba kokukhanya, ilinganiswe ngu "lm", mfutshane "lumen". Iphezulu ixabiso le-lumen, i-bulb ikhanya ngakumbi. Ukuba akuqinisekanga ngamanani e-lumen, le tshathi ye-incandescent kwizibane ze-LED inokukunika umkhondo. Oko kukuthi, xa ufuna i-LED enokufikelela kwisiphumo sesibane se-incandescent se-100W, khetha i-LED ye-16-20W kwaye uya kufumana ukukhanya okufanayo.

Ngaphandle, ngokweendidi ezahlukeneyo zemisebenzi ngokubanzi zifuna amanqanaba ahlukeneyo elumen, ungabhekisa kule datha ilandelayo: inkampu yasebusuku: malunga ne-100 ye-lumen yokuhamba ebusuku, ukuwela (ukuqwalasela utshintsho lwemozulu njengemvula kunye nenkungu) : 200 ~ 500 lumen malunga umzila obalekayo okanye eminye imidyarho yasebusuku: 500 ~ 1000 lumen yokukhangela ebusuku kunye nokuhlangula: ngaphezulu kwe-1000 lumen

Lumka xa usebenzisaizibane zangaphandle(ingakumbi abo bane-lumens ephezulu), musa ukukhomba emehlweni abantu. Ukukhanya okuqaqambileyo kunokubangela umonakalo emehlweni abantu.
