Shin ka fahimci "lumen" da fitila dole ta sani?

A cikin siyanwajekaifitilunkumasansaniFitilu sau da yawa suna ganin kalmar "lumen", shin kun fahimta?

Lumens = Fitowar Haske. A taƙaice, Lumens (wanda aka nuna ta lm) ma'auni ne na jimlar adadin hasken da ake iya gani (ga idon ɗan adam) daga fitila ko tushen haske.

Mafi yawangama gari a wajesansanihaske, fitilar kai ko tocilaFitilun LED ne, waɗanda ke amfani da ƙarancin makamashi don haka suna da ƙarancin ƙimar watt. Wannan ya sa watts ɗin da muka yi amfani da su wajen auna hasken kwan fitila ba su da amfani, don haka masana'antun suna canzawa zuwa lumens.

Lumen, wani yanki na zahiri wanda ke kwatanta kwararar haske, ana ƙididdige shi da "lm", a takaice don "lumen". Mafi girman ƙimar lumen, haka nan yake haskaka kwan fitila. Idan ba ku da tabbas game da lambobin lumen, wannan jadawalin fitilun incandescent zuwa LED zai iya ba ku wata alama. Wato, lokacin da kuke son LED wanda zai iya cimma tasirin fitilar incandescent 100W, zaɓi LED mai ƙarfin 16-20W kuma za ku sami kusan haske iri ɗaya.

A waje, bisa ga nau'ikan ayyuka daban-daban gabaɗaya suna buƙatar matakan lumen daban-daban, zaku iya komawa zuwa bayanan masu zuwa: zangon dare: kimanin lumen 100 na yawo a dare, ketarewa (idan aka yi la'akari da canjin yanayi kamar ruwan sama da hazo): lumen 200 ~ 500 game da gudu a kan hanya ko wasu tsere na dare: 500 ~ 1000 lumen ƙwararru bincike da ceto dare: lumen sama da lumen 1000

Yi hankali lokacin amfanifitilun waje(musamman waɗanda ke da lumens mai yawa), kada ku nuna su ga idanun mutane. Haske mai haske da yawa zai iya haifar da lahani ga idanun mutane.
