Kulesi sihloko sizochaza okuhlukile izinhlobo zama-bulb, ezisetshenziswa kakhulu emakhaya noma emahhovisi, ngezinzuzo nezinkinga zazo.
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%.
Izici okufanele uzicabangele ngaphambi kokwazi izinhlobo zama-bulb:
1. Ukusebenza kahle, okungama-watts (w) adliwe yizinhlobo ezahlukene zama-light.
2. Isikhathi sokusebenziseka, okusho isikhathi ngasinye sezinhlobo zama-bulbs.
3. Umbala, ngoba ukukhanya okuzokhipha kuzoba phuzi noma kumhlophe ngokuya ngokukhetha phakathi kwezinhlobo ezahlukahlukene zama-bulb. Lokhu kuzoya ngobuchwepheshe obukhethayo, ngoba kungaba i-LED, i-eco halogen noma i-fluocompact.
4. Imijikelezo Futhi kungezinye izinto okufanele uzinakekele lapho ukhetha phakathi kwazo zonke izinhlobo zama-bulb akhona, ngoba i-bulb ngayinye isungule ukuthi zingangaki izikhathi ezingavulwa futhi zicishwe.
Enye into okufanele uyikhumbule ukuthi ku Amandla okonga amalambu sizikala ngokuya ngeyakho ukukhanya, ngokusebenzisa iyunithi yokukala ebizwa ngokuthi “ukhanyisa"Noma"amalambu”Okukhombisa nje inani lokukhanya okukhishiwe.
Esikhundleni salokho, okungenhla ama-incandescent bulbs kulinganiswe ngo ama-watts (W), ekhombisa ukuthi kungakanani ugesi kudle.
Yini amaLumens? Nokuthi ungawabala kanjani
Umbuzo wokuqala okumele sizibuze wona ukuthi sizibuze ukuthi yini iLumen?
- Amalambu, iyunithi ye-International System of Measurements yokukala ukukhanya okukhanyayo, isilinganiso samandla okukhanya akhishwa ngumthombo, kulokhu isibani esikhanyayo. Igilobhu ngalinye eliholelekile livame ukudala amalambu aphakathi kuka-60 no-90, ngakho-ke singakubala lokho isibani esisodwa se-15W LED banganikela nge okukhipha ukukhanya okungaba ngu-1050 lumens. Yini okungahle kube ngaphansi kokukhanya ukuthi kukhiqizwa isibani esingu-65W incandescent.
- Lokhu kufana kungumphumela wefomula elandelayo: Amalambu wangempela = Inani lamaWatts x 70.
Ukukhanya okunconyiwe kwamagumbi asendlini
Ngemuva kwakho konke lokho okuchaziwe, singabona isibonelo esisebenza kakhulu esizoba nokwazi mangaki amandla okonga amandla adingekayo yesikhala esithile, okungaba noma yiliphi igumbi endlini.
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 likhanyiswe ngebhalbhu elikhanyayo 400 amalambu, futhi indawo yegumbi ingamamitha-skwele angama-20, izinga lokukhanyisa lizoba ngama-20 lx.
Ngokuya ngale yunithi, kunezibalo ezinconywayo zezinga lokukhanyisa endaweni yasekhaya, ngokuya ngezidingo zesikhala ngasinye endlini:
- Igumbi lasekhishini: isincomo sokukhanyisa okujwayelekile siphakathi kuka-200 no-300 lx, noma ngabe sendawo ethile yokusebenza (lapho ukudla kusikwa futhi kulungiswa khona) ikhuphukela ku-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.
Izinhlobo zama-bulb namathiphu wokuzikhetha
Ama-Led amahle kakhulu
Ziyisichazamazwi seLight Emitting Diode. I- ama-led aholelekile Zihambisana kakhulu nemvelo, ngoba zimelela inketho yemvelo futhi isebenza kahle.
Lokhu kungenxa yokuthi azikhiphi i-CO2 eningi emvelweni njengezinye izinhlobo zama-bulb, futhi futhi ungalethi i-tungsten noma i-mercury.
Futhi uma sihlaziya ifayela le- izici eziyinhloko kuphawulwe ngenhla, isikhathi sezinhlobo ezahlukahlukene zama-bulb, ama-LED angasetshenziswa cishe amahora ayizinkulungwane ezingamashumi amahlanu. Ukonga ngokuya ngokusetshenziswa kungaphezu kokubalulekile, ngoba sizobe sisebenzisa cishe ama-80% ngaphansi kuka noma iyiphi enye isibani sendabuko.
Ama-Eco halogen bulbs amahle kakhulu.
Ukukhanya okunikezwa yilezi zinhlobo zama-bulb kungokwemvelo ikakhulukazi futhi kuvuleka ngokushesha. Mayelana nokuphila kwayo okusebenzisekayo, imvamisa kuba amahora ayizinkulungwane ezimbili, kudla imvilophu ingxenye eyodwa kwezintathu ingaphansi kunalezi ezizi-incandescent, esizophawula ngazo ngezansi.
Ukulahleka kwamandla ngenxa yomphumela wokushisa kufanele kucatshangelwe, ngoba lolu hlobo lwama-light light zikhipha ukushisa.
Ama-incandescent bulbs.
Ukusetshenziswa kwamandla kuphezulu kunawo wonke ama-bulbs, esizobona ukuthi kukhonjisiwe ngokuhamba kwesikhathi ugesi bill.
Ngenhlanhla, kusukela ngo-2009 kuye phambili, ibikhiqiza ukuhoxiswa kwalolu hlobo lwama-light emakethe, inikezela ngezixazululo ezingcono ezinikeza umphumela ofanayo ngokukhanya, kepha ngokusetshenziswa okuphansi kakhulu. Ngasikhathi sinye inenani eliphakeme lemijikelezo, azikhiqizi ukushisa futhi zikhiqiza kabusha i- faka umbala kahle.
Ama-Fluocompact bulbs amahle kakhulu.
Lezi zinhlobo zama-bulb zaziwa njenge comsumption ongaphakeme; ukuba nempilo esebenzisekayo ephakathi kwamahora ayizinkulungwane eziyisikhombisa kuya kweziyishumi, futhi kudla phakathi kwamaphesenti angama-75 no-80% ngaphansi kwama-bend yendabuko
Ngokuqondene nokukhanyisa ekunikezayo, lezi izinhlobo zamandla okonga amandla Azinconyelwa kakhulu ukuthi zisetshenziswe ezindaweni zokuhamba. Ngoba imvamisa kuthatha imizuzwana embalwa ngaphambi kokunikela nge- amandla okukhanyisa kwakho.
Yiziphi izici okufanele zicatshangelwe?
a) Isikhathi esithatha isibani sokukhanya ukufinyelela ukusebenza okuphezulu, okungukuthi, ivula ngokushesha kangakanani.
b) I-aperture angle noma i-light beam, okusho ukuthi engeli engezansi, ukukhanya kuzogxila ephuzwini elithile.
c) Isikhathi sokusebenziseka kwesibani, okungukuthi, i- amahora okukhanya kwesibani.
d) Ngokombono wobuhle, sizozinakekela amafomu. Singathola ama-globe, round, spiral noma ama-bulb.
e) Kukhona futhi ukwakheka okuhlukile kwe-bushing ngokuya ngobubanzi bayo futhi uhlobo lwentambo ukuthi babe.
f) Inani lezikhathi isibani esikhanyayo ingavulwa icishwe, okungukuthi, imijikelezo yabo.
g) Amandla wokukhanya noma okukhanya, ngendlela yokuthi ubuningi be lumens sizothola ukukhanya okukhulu.
