Kusankha nyali: angati lumens pa Watt incandescent babu 100?

Lumen (wowala kamwazi) ndi gulu la muyeso wa SI - System Mayiko mayunitsi. Khalidwe limeneli kuwala, amaimira "lumens" kapena lm.

nyali m'malo

kuwerengetsera The akhala wasonyeza kuti incandescent nyali - si njira yabwino kwambiri kuunikira, makamaka pankhani m'madera ambiri. gawo la mikango mphamvu si mu kuunikira ndi Kutentha ndi filament, zomwe zimapangitsa getsi ngati chotenthetsera yaing'ono.

Funso la mphamvu zipatso ndi zofunika makamaka tsopano, mu nthawi ya mowa mkulu chuma ndi, Chofunika kwa ogula, wokwera pa zofunikira. Choncho, pamene inu kugula ayenera kulabadira kuti mphamvu, amayezedwa Watts, ndi mmene kuwala kuyatsa. Ndipo monga chizindikiro lisinthike lumens.

lumens angati pa Watt incandescent babu 100

nyali amenewa amapezeka kawirikawiri ntchito mu malo zogona. Iwo kupereka kuyatsa wabwino ndi omasuka diso mtundu. Popeza Lumens akusonyeza mmene kuwala panamveka ndi gwero kwambiri, mtengo, ndi owala kuwala. Komabe, Chiwerengerochi angakhale zimasiyanasiyana, makamaka pankhani osiyanasiyana nyali. N'zovuta kudziwa mmene lumens ambiri incandescent nyali 100 Watts. Mwachitsanzo, 20 Watt nyale apase kamwazi 250 lumens, ndipo ngati mphamvu kawiri, otaya lidzafika 400 lm. Koma 60 Watt babu mu mlingo wa pafupifupi 700 lumens 900 lumens wofanana ndi mphamvu ya 75 Watts. The otaya mphamvu 1200 lumens kuwala zimatheka ngati mphamvu ya nyali filament 100 Watts.

mphamvu kukhathamiritsa

Pasanapite nthawi yaitali, anthu ayamba kuganizira mmene kupulumutsa pa magetsi, chifukwa patsogolo alibe kuima. Choyamba anadza mababu mphamvu yopulumutsa, limene, mogwirizana ndi Mlengi, kuchepetsa mowa mphamvu mu nthawi ziwiri kapena zitatu. Ndipo tsopano pali zambiri mafuta imayenera mababu - LED. zoipa basi - mtengo si mkulu, kotero vuto lalikulu ndi nyali yatsopano m'gulu ndipo kochepa mowa mphamvu, ndi kuwala kwa nyali incandescent.

chinyengo

magetsi LED chiyani zimawononga mphamvu kangapo zochepa, koma mudziwe kuti Mlengi, nthawi zambiri kukusokonezani wogula. Mwachitsanzo, kuti nyale ofanana 70 Watt getsi ndi lumens 500, koma sizingakhale zoona. Pofuna kuonedwa ndi kusankha, tiyenera kukumbukira lumens angati mu incandescent nyali 100 Watts.

Pambuyo kugula chinthu ichi munthu kukhumudwa chifukwa kuwala sikokwanira ndipo kusintha kwa chipangizo amphamvu kwambiri, omwe amagwirizana ndi ndalama zina, makamaka ngati mababu a anagulidwa kwa chandelier lonse. Komabe, pamene kusintha m'pofunika kulabadira osati ndi kukula monga lumens. Wowala kamwazi / mphamvu - chiŵerengero izi mu System Mayiko mayunitsi (SI) wotchedwa Mwachangu wowala. Kunena mwachidule, chizindikiro limasonyeza mmene kuwala zotuluka 1 Watt wa gwero kuwala. Amayezedwa lumens pa Watt.

Kodi kusankha?

Mogwirizana magawo onse, muyenera kuganizira mmene ambiri lumens pa Watt incandescent nyali 100, koma linanena bungwe kuwala imene wofanana 100 Watts a 13.8 lm / W. Mwachitsanzo: ndi chizindikiro chomwecho mu mababu LED kungakhale 10 300 lm / W (!).

Ubwino wina wosatsutsika ndi chilungamo cha galasi filament nyale ndi mbali ya mtengo kufala kwa madigiri 360. Choncho, kusintha kwa mitundu ina (mwachitsanzo, inatsogolera nyale ngodya kawiri zochepa) akhoza anati kudzitsitsa zounikira. Komanso, ndi incandescent nyali ndi abwino kwa dimmers kuti angathe kulamulira osati kuwala, komanso kumwa mphamvu.

zolemba

Monga ulamuliro, mudziwe lumens angati pa Watt incandescent nyali 100, mungazipeze pa ma CD. Komanso, pali anasonyeza komanso magawo zofunika monga mtundu kutentha ndi mtundu mamasuliridwe index (CRI), ndi ufulu wosankha zomwe, inu mungawapange omasuka kwambiri kwa maso kuwala mthunzi.

Mtundu kutentha mwambo incandescent nyali ndi 2800 K (amayezedwa madigiri Kelvin). Khalidwe limeneli ndi ayenera kutsatira posankha woyererako kumene, ngati malo. Pakuti workspaces (maudindo, zipatala, pharmacies, masitolo) abwino malankhulidwe ndale ndi mtundu kutentha kwa 4000 kuti 5000 K, ndi tambirimbiri ndipo maholo chionetsero tikulimbikitsidwa kuphimba kuwala fulorosenti (5000 K ndipo pamwamba).

olondola

Ngati pa zifukwa zina n'kofunika kuti kuyatsa pamene m'malo nyali amakhala ndendende pa mlingo yemweyo, kungakhale chisanadze anayeza kuwala linanena bungwe ndi chipangizo wapadera - mita kuwala. Maapatimenti - muyeso wa chiŵerengero cha lumens ndi Area (1 lux ndi wofanana lumen imodzi mita lalikulu). Kawirikawiri zimenezi zikugwira ntchito kwa mabungwe osiyanasiyana, kumene m'pofunika kuyan'ana litsatidwe malangizo kuyatsa boma.

Zidule pa mphamvu Mwachangu

Mmodzi mwa nsonga chidwi akatswiri ndi ntchito nyali za mphamvu zosiyana. Mwachitsanzo, chiwalitsiro wamphamvu kwambiri chofunika m'dera ntchito chipinda, ndi m'madera ena n'zotheka angayendetsere ochepa zipinda zazikulu zokhala. Chachiwiri nsonga - Osiyana kusinthitsa a nyale. tsenga Izi osati zimawononga wochepa mphamvu, komanso kugawana bandi mu situdiyo nyumba kapena zipinda zazikulu.
