Okwangoku, inkcitho yokukhanyisa imele I-18% yokusetyenziswa kwamandla ezindlini kwaye ngeenxa zonke kwi I-30% kwii-ofisi, ngokweentlawulo zombane. Indlela esebenzayo yokunciphisa ezi ndleko kukukhetha uhlobo olufanelekileyo lokukhanyisa. Ukuba sikhetha i izibane ezichanekileyo Kwisithuba ngasinye, sinokugcina phakathi I-20% kunye ne-80% yamandla.
Ukufezekisa oku kongiwayo, kubalulekile ukukhetha Ukonga umbane iibhalbhu. Ezi zahlulwe ngokwazo ukukhanya kusetyenziswa njengeyunithi yomlinganiselo izibane, ezibonisa ubungakanani bokukhanya okukhutshwa yibhalbhu.
Kwelinye icala, kunye ne Iibhalbhu ezibengezelayo (oyena mdala), ireferensi iya kwenziwa kwi watts (W), elinganisa ukuba yimalini umbane bayadla. Ukufudukela kwi-lumens njengeyunithi yokulinganisa akusivumeli nje ukuba sibale ngcono ukukhanya esikufunayo, kodwa kunika indlela echanekileyo yokuvavanya ukusetyenziswa kwamandla.
Yintoni ilumen?
Ukuqonda indlela yokubala i-lumens, kufuneka siqale sazi ukuba yintoni ilumen. I izibane unyana la iyunithi yomlinganiselo wamazwe ngamazwe esetyenziselwa ukwenza ubungakanani be ukukhanya okukhanyayo. Le datha isinika ulwazi malunga ne amandla okukhanya ukuba umthombo wokukhanya, onjengebhalbhu yesibane, uyakhupha.
Kwimeko yeebhalbhu ze-LED, kukho ifomyula elula yokuqikelela ukuba zingaphi ii-lumens ezinikezelwa yibhalbhu:
- Izibane zokwenyani = inani leewatts x 70.
Lo mba we-70 lixabiso eliqhelekileyo elisebenza kwiibhalbhu ezininzi ze-LED kwiimarike. Umzekelo, ibhalbhu ye-LED eyi-12W inokubonelela nge-840 lumens, isixa esifanayo sokukhanya kwibhalbhu ye-incandescent engama-60W, kodwa okonga 48W.
Indlela yokubala umgangatho wokukhanyisa ofanelekileyo kwigumbi ngalinye
Ukukhanyisa akufuneki kugqithise okanye kunganelanga. Kubalulekile ukuba zonke iindawo zendlu zikhanyise kakuhle ngokweemfuno zakho. Ukukhanya okugqithisileyo kunokubangela ukudinwa okubonakalayo, ngelixa ukukhanya okungahambi kakuhle kunokubangela ukungahambi kakuhle kwaye kugxininise amehlo akho.
Ukufumana ukuba zingaphi iiglowubhu zombane ezisetyenziswa kancinci ezifunekayo kwigumbi, sinokuzisebenzisa luxes, ezilumlinganiselo we amandla okukhanya. I-Lux ichazwa njengobungakanani bokukhanya okuwela kwindawo ephezulu yesikwere semitha.
Umzekelo, ukuba unebhalbhu ye-lumen eyi-150 ekhanyisa igumbi le-10 square meter, inqanaba lokukhanya liya kuba yi-15 lux.
Imigangatho yokukhanya ecetyiswayo endlwini:
Kukho iingcebiso ngokubanzi malunga namanqanaba okukhanyisa ekufuneka abe kwiindawo ezahlukeneyo zekhaya:
- Ukupheka: Okufanelekileyo kukukhanya okuphakathi kwe-200 kunye ne-300 ye-lux yokukhanyisa ngokubanzi, kunye nokuya kuthi ga kwi-500 lux kwiindawo ezifana ne-countertop, apho ukutya kulungiselelwa khona.
- Igumbi yokuhlala: Uluhlu lwe-100 ukuya kwi-300 lux lunconywa ukuba lukhanyise ngokubanzi. Ukuba uza kufunda, kuyacetyiswa ukuba ube nesibane esigxilileyo ukuya kuthi ga kwi-500 lux.
- Amagumbi okulala: Kumagumbi okulala abantu abadala, amanqanaba angama-50 ukuya kwi-150 lux acetyiswa ngokukhanya okuqhelekileyo. Ukufunda entloko ebhedini kufuna ukuya kuthi ga kwi-500 lux. Kumagumbi abantwana, ukukhanya ngokubanzi ukuya kuthi ga kwi-150 lux kucetyiswa.
- Baño: Ngokubanzi, malunga ne-100 lux yanele, kodwa kwindawo yesibuko amanqanaba e-500 lux kufuneka afikeleleke kwimisebenzi efana nokucheba okanye ukwenza izimonyo.
Ukuba sithatha ezi ngcebiso, kuya kuba lula ukubonelela indawo nganye ngezinga elifanelekileyo lokukhanya, eliya kuba negalelo ekuphuculeni induduzo kwigumbi ngalinye.
Ukubala inani leebhalbhu ezifunekayo kwigumbi, phinda-phinda ii-square metres zegumbi ngenani elicetyiswayo le-lux uze ulahlule elo xabiso ngenani lebhalbhu enikwe yibhalbhu nganye.
IiWatts ukuya kwitheyibhile yokulingana kwelumens
Utshintsho ukusuka kwiiwatts ukuya kwilumens lunokubabhida abo bangekaqhelani nale metric. Ngeso sizathu, ngezantsi kukho itafile yokuthelekisa ebonisa ukulingana phakathi kwe-lumens kunye ne-watts kwiintlobo ezahlukeneyo zeebhalbhu zokukhanya, kubandakanywa i-LED, i-incandescent, i-halogen kunye ne-fluorescent:
| Ixabiso kwi-lumens (lm) | iiglowubhu | Incandescent | Halogens | I-CFL kunye ne-fluorescent |
| 50 / 80 | 1,3W | 10W | - | - |
| 110 / 220 | 3,5W | 15W | 10W | 5W |
| 250 / 440 | 5W | 25W | 20W | 7W |
| 550 / 650 | 9W | 40W | 35W | 9W |
| 650 / 800 | 11W | 60W | 50W | 11W |
| 800 / 1500 | 15W | 75W | 70W | 18W |
| 1600 / 1800 | 18W | 100W | 100W | 20W |
Ukusetyenziswa Iibhalbhu ezikhokelwayo ziya zithandwa kakhulu njengoko zibonelela ngokusebenza kakuhle kwamandla. Ubudlelwane phakathi kwe-lumens kunye ne-watts bubalulekile ukumisela uhlobo oluchanekileyo lwebhalbhu kwaye, ngaphezu kwako konke, ukonga kwityala lakho lombane. Ukuqwalasela imiba efana nokukhanya kokukhanya kunye nomphezulu oza kukhanyiswa uqinisekisa ukuthuthuzela okubonakalayo kwamagumbi, ngelixa ukusetyenziswa kwamandla oxanduva kuqhutyelwa.
Kucacisiwe kakuhle. Enkosi
