Empeleni, njengamanje u-18% usetshenziselwa ukukhanyisa emakhaya nangaphezulu kwama-30% emahhovisi enani lentengo yomthetho wethu kagesi. Uma sikhetha uhlobo lwe ukukhanyisa okwanele ekusetshenzisweni ngakunye, sizokuthola yonga amandla angama-20% kuya kwangama-80%.
Ukonga kudingeka sisebenzise Amandla okonga amalambu, futhi lezi sizihlukanisa ngokweziqu zazo ukukhanya, ngokusebenzisa iyunithi yokukala "ukhanyisa"Noma"amalambu”, Okukhombisa inani lokukhanya okukhishiwe.
Ngokuphambene nalokho, ama-incandescent bulbs (endala) isilinganiso sabo kwakuyi- ama-watts (W), lokhu kukhombisa ukuthi kungakanani ugesi kudle.
I-athikili elandelayo izama ukuchaza ukuthi ungabala kanjani ama-Lumens ama-bulbs.
Kuyini iLumen? nokuthi ungazibala kanjani
Umbuzo wokuqala okumele sizibuze wona ukuthi sizibuze ukuthi yini amaLumens?
- Ama-lumens, iyunithi ye-International System of Measurements yokukala ukukhanya okukhanyayo, isilinganiso samandla akhanyayo ikhishwe ngumthombo, kulokhu isibani esikhanyayo.
- Ukwazi amalambu lokho kukhiqiza isibani se-LED Kukhona ifomula: amalambu wangempela = inani lama-watts x 70, 70 ngokuba inani elijwayelekile esilithola kuma-bulb amaningi. Kusho ukuthi, isibani se-12W LED inganikela ngokukhipha okungu-840 lm. Lokho okungaphezulu noma okuncane yilokho okwakha ifayili le- Isibani se-incandescent esingu-60W. Njengoba ukwazi ukubona, ngokukhiqiza isibani esifanayo sokukhanya, sigcina ama-48w ngebhalbhu ngayinye ye-incandescent esiyishintshayo.
Izikhala ezikhanyiswe kahle
Ukwenza ngcono ukunethezeka kwamagumbi ahlukene wendlu, wonke kufanele akhanyiswe kahle. Futhi kubalulekile ukwazi lokho "Kukhanyiswe kahle" kusho ukuthi isikhala ngasinye kufanele sibe nokukhanya okwanele: noma ngaphezulu noma ngaphansi kokudingekayo. Uma inani lokukhanya linganele, amehlo ayaphoqeleka ukuthi asebenze ngokweqile, futhi lokhu kuholela ekukhathaleni okubukwayo, okugcina kubangele izimpawu ezinjengokuphathwa yikhanda, ukucasuka kwamehlo nokuncinza, isisindo emajwazini amehlo, njll.
Ukukhanya okunconyiwe kwamagumbi asendlini
Lapho iyunithi selichazwe kahle, singazama ukubala mangaki amandla okonga amandla adingekayo yesikhala esithile, okungaba yinoma iyiphi ingxenye yendlu.
Ukwazi ini Izinga lokukhanyisa Kunconywa, kufanele sibheke kwifayela le- lux. Lona iyunithi yokuqina kokukhanya kwe-International System, yesimbuli lx, okulingana nokukhanyiswa kwendawo okuvame ukuthola ngokufanayo ukukhanya okukhanyayo kwe-1 lumen ngemitha eyisikwele.
Lokho kusho ukuthi, uma igumbi likhanyiswa ngebhalbhu elikhanyayo I-lumen engu-150, nendawo yegumbi ingamamitha-skwele ayi-10, izinga lokukhanyisa lizoba yi-15 lx.
Ngokuya ngale yunithi, kunezibalo ezinconywayo zezinga lokukhanyisa endaweni yasekhaya, ngokuya ngezidingo zesikhala ngasinye endlini:
- Igumbi lasekhishini: izincomo zokukhanyisa okujwayelekile ziphakathi kuka-200 no-300 lx, noma ngabe indawo ethile yokusebenza (lapho ukudla kusikwa futhi kulungiswa khona) inyukela kuma-500 lx
- Amakamelo okulala: kwabadala, hhayi amazinga aphakeme kakhulu anconyelwa ukukhanyisa okujwayelekile, phakathi kuka-50 no-150 lx. Kepha enhloko yemibhede, ikakhulukazi yokufunda lapho, kunconywa amalambu agxile afinyelela kuma-500 lx. Kumakamelo ezingane kunconywa ukukhanya okujwayelekile okuthe xaxa (150 lx) futhi cishe ngama-300 lx uma kunendawo yomsebenzi nemidlalo.
- Igumbi lokuphumula: Ukukhanyisa okujwayelekile kungahluka phakathi kwe-100 ne-300 lx, yize ukubukela ithelevishini kunconywa ukuthi wehle uye cishe kuma-50 lx nasekufundeni, njengasekamelweni, ukukhanyisa 500 lx kugxilwe.
- Ukugeza: awudingi ukukhanyisa okuningi, cishe i-100 lx yanele, ngaphandle kwendawo yesibuko, ukushefa, ukufaka ukwakheka noma ukukama izinwele zakho: cishe i-500 lx nayo iyanconywa lapho.
- Izitebhisi, imihubhe nezinye izindawo zokuhamba noma ukusetshenziswa okuncane: okuhle ukukhanyisa okujwayelekile kwe-100 lx.
Ithebula Lokulingana
Ukwenza lula ukushintsha kusuka kuma-watts kuye ku- amalambu, okuyinto entsha, kunetafula elenza kubelula ukubala ngokushesha ama-watts kuya kumalambu:
| Amanani ku-lumens (lm) | CISELELA UKUSETSHENZISWA KWE-WATTS (W) NGOKUHLOBO LWESIBANI | |||
