Ukukhanyaikhona yonke indawo ekuphileni kwethu, futhi asihlukani nayo. Lapho uhlobisa indlu, kubaluleke kakhulu ukukhetha okufaneleisibani sophahla, ngoba izindawo zokufaka izicelo zeIzibani zophahla lwe-LEDaguqulwa asuka kovulandi namaphasishi ayiswe emakamelweni okuhlala, amagumbi okulala nezinye izindawo.
Nokho, kunezinhlobo eziningiizibanifuthiizibaniemakethe manje, futhi akulula ukukhetha. Lapha, ake sixoxe ngokuthi ungakhetha kanjani aisibani sophahla.
1. Bheka umthombo wokukhanya
Ngokuvamile, izibani ze-incandescent zinesikhathi esifushane sokuphila kanye nokusebenzisa amandla aphezulu; izibani ze-fluorescent zinezakhiwo ezingcono zokonga amandla, kodwa imvamisa ephezulu ye-stroboscopic, ezothinta umbono; amalambu okonga amandla mancane ngosayizi futhi anesikhathi eside sokuphila.Izibani ze-LEDzincane ngosayizi, zinde empilweni, azinabuthi futhi azihambisani nemvelo.
2. Buka isimo
Ukuma kanye nesitayela se-isibani sophahlakufanele ihambisane nesitayela somhlobiso wakho jikelele. Isibani ekuqaleni siwukuqeda. Isitayela kanye nebanga lokuhlobisa kufanele futhi kucishwe izibani.Lokhu kuncike embonweni wobuhle bomuntu ngamunye, inqobo nje uma uthanda.
3. Bheka amandla
Ayikho imithethonqubo ecacile yeizibani zophahla, futhi amandla asetshenziswa kakhulu yi-10W, 21W, 28W, 32W, 40W, njll.
Izinto okufanele uzikhumbule lapho uthenga izibani:
1. Ezokuphepha
Lapho ukhetha isibani, awukwazi ukuhaha ngokungaboni, kodwa kufanele uqale ubheke izinga laso futhi uhlole ukuthi isitifiketi sewaranti nesitifiketi seziqu kuphelele yini. Ukumba eqolo akukona ukuthi kuhle, kodwa ishibhile kakhulu kumele kube kubi. Izinga lezibani eziningi alilungile ngokwanele, futhi ngokuvamile kunezingozi ezifihlekile ezingapheli. Uma kwenzeka umlilo, imiphumela ayicabangeki.
2. Naka isitayela esifanayo
Umbala, ukuma kanye nesitayela sesibani se-ceiling kufanele kuhambisane nesitayela sokuhlobisa kwangaphakathi kanye nefenisha.
3. Ukuhlola
Isibani ngokuyinhloko senziwe ngengilazi, entekenteke futhi nakanjani izoklwejwa noma ilimale ngemva kokuhamba ibanga elide.
Ukungaqondi kahle okubili okukhulu lapho uthenga amalambu ophahleni:
1.Phatha i-engeli yokukhanyisa yangempela njenge-engeli esebenzayo
I-engeli ekhanyayo yokukhanya kophahla lwe-LED ihlukaniswe nge-engeli esebenzayo kanye ne-engeli ekhanyayo yangempela. I-engeli ephakathi kokuqondisa lapho inani lokuqina elikhanyayo liyingxenye yenani le-axial intensity kanye ne-eksisi ekhanyayo i-engeli esebenzayo. Izikhathi ezi-2 i-engeli yenani elinguhhafu i-engeli yokubuka (noma i-engeli yamandla uhhafu) i-engeli yangempela ekhipha ukukhanya. Ama-engeli angaphandle kwengxenye ye-axial intensity awabalwa njengama-engeli asebenzayo ezinhlelweni zokusebenza ngenxa yokuthi ukukhanya kubuthakathaka kakhulu.
Ngakho-ke, kufanele sinake i-engeli yangempela yokukhishwa kokukhanya komkhiqizo lapho uthenga imikhiqizo. Lapho kubalwa inani lemikhiqizo esetshenziswe kuphrojekthi, i-engeli yangempela yokukhishwa kokukhanya izoba khona, futhi i-engeli ekhipha ukukhanya esebenzayo ingasetshenziswa njengenani eliyinkomba.
2. Ukulindela okweqile empilweni yangempela yesevisi
Ukuncishiswa kwe-lumen kwamalambu ophahleni we-LED kuthintwa izimo ezehlukene zemvelo ezifana nezinga lokushisa le-ambient, umswakama, nomoya omncane. Ukubola kwe-Lumen kuphinde kuthinteke ekulawuleni, ukuphatha okushisayo, amazinga amanje nokunye okuningi okucatshangelwayo kokuklanywa kukagesi.
Ukufingqa, okufanele sikunake lapho sithenga izibani zophahla lwe-LED yijubane layo lokubola kokukhanya, hhayi isikhathi sokusebenzisa.
Izinzuzo kanye nezitayela zentuthuko zesikhathi esizayo zamalambu ophahleni:
1. Ukusebenza kahle okukhanyayo kwe-LED ngokwayo sekufinyelele ngaphezu kuka-130lm/W. Ngokuzayo, ukusebenza kahle okukhanyayo kwezibani zophahla lwe-LED kuzoba ngaphezulu, futhi amandla kagesi nawo angasindiswa kakhulu.
2. Impilo ende, engenawo i-mercury, inganikeza ukukhanya kwamazinga okushisa emibala ehlukahlukene njengoba kudingeka, futhi inezindleko eziphansi nesisindo esilula. Manje kunezitayela eziningi zezibani zophahla ezihlakaniphile emakethe, futhi ukuthuthukiswa kwesikhathi esizayo akupheli.
