Ngapha koko, okwangoku i-18% ichithwa ekukhanyeni emakhayeni nakwi-30% kwii-ofisi zexabiso lebhili lethu lombane. Ukuba sikhetha uhlobo lwe ukukhanya okwaneleyo kusetyenziso ngalunye, siya kufumana yonga amandla aphakathi kwama-20% nama-80%.
Ukugcina kufuneka sisebenzise Ukonga umbane iibhalbhu, saza sahlulahlula ngokwazo ukukhanya, ngeyunithi yokulinganisa "ukukhanya"Okanye"izibane”, Ebonisa ubungakanani bokukhanya okubonisiweyo.
Okuphikisanayo, Iibhalbhu ezibengezelayo (endala) umlinganiso wabo ibingu watts (W), oku kubonisa ukuba ungakanani umbane tya.
Inqaku elilandelayo lizama ukucacisa indlela yokubala iiLumens zeebhalbhu.
Yintoni iLumen? nendlela yokubala
Umbuzo wokuqala ekufuneka sizibuze wona kukuzibuza ukuba zithini iiLumens?
- Izikhanyiso, iyunithi yeNkqubo yeMilinganiselo yeHlabathi yokulinganisa ukubhobhoza okukhanyayo, umlinganiso wamandla akhanyayo ikhutshwe ngumthombo, kule meko ibhalbhu yesibane.
- Ukwazi ukukhanya ivelisa ibhalbhu ye-LED Kukho ifomula: ukukhanya kwenyani = inani leewatts x 70, 70 ngamaxabiso aphakathi esiwafumana kwii-bulbs ezininzi. Oku kuthi, Ibhalbhu ye-12W ye-LED inganikezela ngemveliso yokukhanya eyi-840 lm. Okungaphezulu okanye okuncinci kuko okuvelisa i I-60W incandescent bulb. Njengoko ubona, ngokuvelisa ukukhanya okulinganayo, sigcina i-48w kwibhalbhu nganye ye-incandescent esiyitshintshayo.
Iindawo ezikhanyisiweyo
Ukuphucula ukonwaba kwamagumbi ahlukeneyo endlu, onke kufuneka akhanyiswe kakuhle. Kwaye kubalulekile ukuyazi loo nto "Ukhanyisile" kuthetha ukuba indawo nganye kufuneka ibe nezibane ezaneleyo: kungabikho ngaphezulu okanye ngaphantsi kokufunekayo. Ukuba inani lokukhanya alonelanga, amehlo ayanyanzelwa ukuba asebenze ngokugqithileyo, kwaye oku kukhokelela ekudinweni okubonakalayo, nto leyo ethi ibangele iimpawu ezinjengeentloko, ukucaphuka kwamehlo kunye nokuhlaba, ubunzima kwiinkophe, njl.
Ukukhanya okucetyiswayo kwamagumbi asendlwini
Nje ukuba iyunithi ichazwe kakuhle, singazama ukubala zingaphi iibhalbhu zokugcina amandla ezifunekayo yendawo ethile, enokuba yeyiphi na indawo yendlu.
Ukwazi ukuba yintoni Inqanaba lokukhanyisa Kuyacetyiswa, kufuneka sibhekise kwi lux. Yiyo Icandelo lokuqina kokukhanya kweNkqubo yeHlabathi, yesimboli lx, elingana nokukhanya komphezulu wesiqhelo ofumana ngokufanayo ukukhanya okukhanyayo kwe-1 lumen kwimitha nganye nganye.
Oko kuthetha ukuba, ukuba igumbi likhanyisiwe ngebhalbhu yesibane I-lumen eyi-150, kunye nendawo yegumbi zi-10 yeemitha zesikwere, inqanaba lokukhanyisa liya kuba lx-15
Ngokusekwe kule yunithi, kukho amanani acetyiswayo wenqanaba lokukhanyisa kwimeko yasekhaya, kuxhomekeke kwiimfuno zendawo nganye endlwini:
- Ikhitshi: Isindululo sokukhanyiswa ngokubanzi siphakathi kwama-200 nama-300 lx, nangona kwindawo yokusebenza ethile (apho ukutya kunqunqwayo kwaye kulungisiwe) kunyukela ukuya kuma-500 lx
- Amagumbi okulala: Kubantu abadala, hayi amanqanaba aphezulu kakhulu acetyiswayo ngokukhanyisa ngokubanzi, phakathi kwe-50 kunye ne-150 lx. Kodwa entlokweni yeebhedi, ngakumbi xa kufundwa apho, izibane ezijolise kwi-500 lx ziyacetyiswa. Kucetyiswa kumagumbi abantwana ukukhanya kancinci ngakumbi (150 lx) kwaye malunga ne-300 lx ukuba kukho umsebenzi kunye nendawo yemidlalo.
- Igumbi yokuhlala: Izibane ngokubanzi zinokwahluka phakathi kwe-100 kunye ne-300 lx, nangona ukubukela umabonwakude kucetyiswa ukuba wehle uye kuthi ga kwi-50 lx nasekufundeni, njengakwigumbi lokulala, isibane I-500 lx ijolise.
- Ibhafu: awudingi kukhanyiswa kakhulu, malunga ne-100 lx yanele, ngaphandle kwendawo yesipili, yokucheba, ukufaka i-make-up okanye ukudibanisa iinwele zakho: malunga ne-500 lx ikwacetyiswa apho.
- Izinyuko, iipaseji kunye nezinye iindawo zokuhamba okanye ukusetyenziswa okuncinci: efanelekileyo kukukhanya okuqhelekileyo kwe-100 lx.
Itheyibhile yokulingana
Ukuququzelela ukutshintshela kwiiwatts ukuya izibane, into entsha noko, kukho itafile ebala ngokukhawuleza i-watts ukuya kumbane (iibhalbhu zexabiso eliphantsi):
