Ukukhethwa izibani: bangaki lumens ngayinye watt esikhipha isibani 100?

Lumen (ecucuza elikhanyayo) kuyinto iyunithi yokukala SI - International System of Units. Lokhu value ukukhanya, okhonjiswe "lumens" noma LM.

izibani esikhundleni

Sekuyisikhathi eside i-izibalo kuboniswe ukuthi isibani esikhipha - akuyona inketho eliphumelela kakhulu ukukhanyisa, ikakhulukazi uma kuziwa ezindaweni ezinkulu. share sengonyama eneji alikho kukhanyisa for amalahle intambo, okwenza isibani njenge-heater encane.

Umbuzo eneji elikhiqizayo kubaluleke ngokukhethekile manje, esikhathini ukusetshenziswa okusezingeni eliphezulu kwemithombo kanye, okubaluleke kakhulu abathengi, amanani ephakeme Tinsita. Ngakho-ke, uma uthenga kufanele sinake hhayi amandla, ulinganiswa Watts, futhi kungakanani ukukhanya zilula. Futhi nje lokhu ipharamitha washintsha ngo lumens.

lumens Bangaki ngayinye watt esikhipha isibani 100

izibani ezinjalo ngokuvamile ezisetshenziswa ezindaweni zokuhlala. Bona ukunikeza izibani kuhle futhi ukhululekile ukuba wamehlo. Njengoba lumens abonisa kangakanani ukukhanya ikhishwa wukukhanya umthombo, aba maningi ukubaluleka, le licace ukukhanya. Nokho, lezi zibalo zingase ayahlukahluka, ikakhulukazi uma kuziwa izinhlobo ezahlukene izibani. Kunzima ukubala zingaki lumens i incandescent lamp Watts 100. Ngokwesibonelo, isibani 20-watt unika ecucuza ukukhanya 250 lumens, futhi uma amandla kabili, ukugeleza uyofinyelela 400 LM. Kodwa isibani 60-watt e ezingaba ngu-700 lumens, 900 lumens ulingana namandla 75 Watts. Umthamo ukugeleza 1200 lumens yokukhanya kufinyelelwa uma amandla izibani intambo kuyinto Watts 100.

amandla nokwenza

Ngokuhamba kwesikhathi, abantu sebeqala ucabange indlela ukuba ugcine ugesi, ngoba intuthuko akemi namanje. Kwaqale kwafika ama energy esisindisa, okuyinto, ngokusho umkhiqizi, ukunciphisa amandla ukusetshenziswa ezikhathini ezimbili noma ezintathu. Futhi manje kukhona nakakhulu ama onga - LED. Zabo ezimbi zodwa - intengo impela high, ngakho le nkinga eyinhloko ukuthi isibani esisha ifakiwe futhi sakugcina amandla ukusetshenziswa, futhi ukukhanya isibani incandescent.

nenkohliso

Izibani LED musa kudle amandla kancane izikhathi eziningana, kodwa ulwazi umenzi, ngokuvamile ephambanisa umthengi. Ngokwesibonelo, uthi isibani afana 70-watt light isibani nge lumens 500, kodwa ngeke kube yiqiniso. Ukuze aphanjaniswe kukhethwa, kumelwe sikhumbule lumens eziningi kanjani ngesibani esikhipha 100 Watts.

Ngemva ukuthengwa lento umuntu uyadumala, ngoba ukukhanya akwanele futhi une ukushintsha kudivayisi elinamandla kakhulu, okuyinto lihlotshaniswa izindleko ezengeziwe, ikakhulu uma ama kwathengwa lonke Iqhwa. Nokho, lapho ushintsho kuyadingeka ukuze banake hhayi kuphela usayizi ezifana lumens. Luminous ecucuza / amandla - lokhu isilinganiso e-International System of Units (SI), okuthiwa kahle elikhanyayo. Uma sikubeka kalula, ipharamitha kubonisa ukuthi ukugqama Imiphumela 1 Watt ka umthombo wokukhanya. Ayephila e lumens watt ngayinye.

Kanjani ukukhetha?

Ikhumbula zonke nemingcele, kufanele ucabangele hhayi kuphela bangaki lumens ngayinye watt esikhipha isibani 100, kodwa okukhipha ukukhanya, okuyinto ilingana Watts 100 13.8 LM / W. Ngokwesibonelo: ipharamitha ezifanayo eziyizinhlupheko ama LED kungaba kusuka 10 kuya 300 LM / W (!).

Enye inzuzo elingenakuphikwa iyona obala we ingilazi intambo isibani engela ugongolo ukusabalala 360. Ngakho-ke, lapho beshintsha kwezinye izinhlobo (isibonelo, i-engeli LED isibani kabili ngaphansi) lungase lubonwe nokucekelwa sokukhanyisa. Ngaphezu kwalokho, kuyinto isibani esikhipha ilungele dimmers ukuthi ungakwazi ukulawula hhayi kuphela ukukhanya, kodwa futhi ukusetshenziswa amandla.

amalebula

Njengomthetho, ulwazi lumens eziningi kanjani ngalinye watt esikhipha isibani 100, kungatholakala kwi isembozo. Ngaphezu kwalokho, kukhona akhonjiswa futhi nemingcele ezibalulekile ezifana umbala lokushisa nombala ukuhumusha Inkomba (CRI), ilungelo lokukhetha okuyinto, ungathola ukhululekile kakhulu emehlweni umthunzi ukukhanya.

Color lokushisa esikhipha wesiko Isibani 2800 K (kulinganiswa ngokwamazinga Kelvin). Lokhu value futhi kufanele siqondiswe ekukhetheni kube umbala okhanyayo, yebo, uma indawo yokuhlala. Ukuze zokusebenzela (amahhovisi, izibhedlela, Pharmacy, izitolo) amathoni efanelekayo hlangothi lokushisa umbala 4000 kuya 5000 K, nemipheme kanye amahholo embukisweni Kunconywa ukumboza ukukhanya Fluorescent (5000 K nangaphezulu).

ukunemba

Uma nganoma isiphi isizathu kubalulekile ukuthi ukukhanyisa uma esikhundleni isibani ihlala kahle ezingeni elifanayo, kungaba pre-kulinganiswa okukhipha ukukhanya idivayisi ekhethekile - imitha ukukhanya. Suite - elithile ratio lumens futhi Area (1 lux ilingana komunye inesikhala ngamunye imitha square). Ngokuvamile lokhu kusebenza ezikhungweni ezahlukene, lapho kuyadingeka ukuqapha nokulandela imithetho ukukhanyisa isimo.

Tricks ku Energy Efficiency

Omunye amathiphu ezithakazelisayo ochwepheshe ukusebenzisa izibani kwamandla ezahlukene. Ngokwesibonelo, ukukhanya namandla kakhulu liyadingeka endaweni yokusebenza egumbini, futhi kwezinye izingxenye kungenzeka ukuphatha inombolo ezincane samakamelo. Ithiphu Okwesibili - usuke Hlukanisa sezibani. Lokhu Iqhinga ngeke kuphela kudle isilinganiso samandla esingaphansi, kodwa futhi ukwabelana band efulethini studio noma amakamelo ezinkulu.
