Izibani zomgwaqo omkhuluziyingxenye ebalulekile yengqalasizinda eqinisekisa ukuphepha emgwaqweni. Lezi zibani ezinkulu, ezinde zikhanyisa abashayeli abahamba emgwaqweni omkhulu ebusuku. Kodwa zikhanya kangakanani lezi zibani zomgwaqo omkhulu? Yiziphi izici ezinquma ukukhanya kwazo?
Ukukhanya kwesibani somgwaqo omkhulu kungahluka kuye ngezici ezahlukahlukene, okuhlanganisa uhlobo lokukhanya, ukuphakama kokukhweza, kanye nezidingo ezithile zomgwaqo. Ngokuvamile, izibani zomgwaqo omkhulu zenzelwe ukunikeza izinga eliphezulu lokukhanya ukuqinisekisa ukuphepha komshayeli nokuvumela ukubonakala ngesivinini esiphezulu.
Esinye sezici ezibaluleke kakhulu ezinquma ukukhanya kwesibani somgwaqo uhlobo lokukhanya ngokwalo. Kunezinhlobo eziningana ezahlukene zezibani ezivame ukusetshenziswa ekukhanyiseni emgwaqweni omkhulu, ngasinye sinezinga laso lokukhanya elihlukile. Uhlobo oluvame kakhulu lwesibani olusetshenziswa ekukhanyiseni emgwaqweni omkhulu izibani ze-LED, ezaziwa ngokukhanya kwazo okuphezulu nokuthembeka kwazo. Lezi zibani nazo zisebenza kahle kakhulu, okwenza zibe ukukhetha okuthandwayo ekukhanyiseni emgwaqweni omkhulu.
Ukuphakama lapho kufakwa khona isibani nakho kudlala indima ebalulekile ekunqumeni ukukhanya kwaso. Izibani zomgwaqo zivame ukufakwa ngamafidi angu-30 kuya kwangu-40 ngaphezu komgwaqo ukuze zimbozwe futhi zikhanyise kakhulu. Lokhu kuphakama kusiza nasekuvimbeleni ukukhanya okukhanyayo futhi kusabalalisa ukukhanya ngokulinganayo ngaphesheya komgwaqo.
Ngaphezu kohlobo lwesibani kanye nokuphakama kokufakwa kwaso, izidingo ezithile zomgwaqo nazo ziyizici ezinquma ukukhanya kwezibani zomgwaqo. Isibonelo, imigwaqo emikhulu enemikhawulo yesivinini esiphezulu noma imiklamo yomgwaqo eyinkimbinkimbi ingadinga izibani ezikhanyayo ukuqinisekisa ukuthi abashayeli banokubonakala okwanele. Umklamo othize womgwaqo, njengokugoba komgwaqo kanye nokuba khona kwezithiyo, kuzothinta nezidingo zokukhanya kwezibani zomgwaqo.
Ngakho-ke, izibani zomgwaqo zikhanya kangakanani? I-Illuminating Engineering Society (IES) ithuthukisa amazinga okukhanyisa emgwaqweni achaza amazinga okukhanyisa adingekayo ezinhlotsheni ezahlukene zemigwaqo. Lezi zindinganiso zisekelwe ocwaningweni olunzulu futhi zenzelwe ukuqinisekisa ukuphepha nokubonakala komshayeli. Ngokuvamile, izibani zomgwaqo zenzelwe ukunikeza ukukhanya okuncane okungu-1 kuya ku-20 lux, kuye ngezidingo ezithile zomgwaqo.
Ubuchwepheshe bokukhanyisa buthuthuke kakhulu eminyakeni yamuva nje, okuholele ekuthuthukisweni kwezibani zomgwaqo ezikhanyayo nezisebenzisa amandla amaningi. Izibani ze-LED, ikakhulukazi, sezibe ukukhetha okuthandwayo kokukhanyisa emgwaqweni omkhulu ngenxa yokukhanya kwazo okuphezulu kanye nokusebenza kahle kwamandla. Izibani ze-LED zaziwa nangokuphila kwazo isikhathi eside, okunciphisa izindleko zokulungisa ngokuhamba kwesikhathi.
Kubalulekile ukuqaphela ukuthi nakuba izibani zomgwaqo ezikhanyayo zibalulekile ekuphepheni nasekubonakaleni komshayeli, zidinga nokulinganisela ukuvimbela ukungcoliswa kokukhanya okukhanyayo nokukhanya. Ukukhazimula okuvela ezibanini ezikhanya kakhulu kungathinta ukubonakala komshayeli, kanti ukungcoliswa kokukhanya kungaba nomthelela omubi emvelweni nasezilwaneni zasendle. Yingakho kubalulekile ukuklama nokufaka izibani zomgwaqo ngokucophelela ukuze kunikezwe ukukhanya okwanele ngaphandle kokubangela ukungcoliswa kokukhanya okungadingekile noma ukukhanya.
Ngamafuphi, izibani zomgwaqo zenzelwe ukunikeza izinga eliphezulu lokukhanya ukuqinisekisa ukuphepha nokubonakala kwabashayeli emgwaqweni. Ukukhanya kwesibani somgwaqo kuzohluka kuye ngezici ezifana nohlobo lokukhanya, ukuphakama kokufakwa, kanye nezidingo ezithile zomgwaqo. Njengoba ubuchwepheshe bokukhanyisa buthuthuka, kulindeleke ukuthi sibone izibani zomgwaqo ezikhanyayo nezisebenzisa amandla amaningi esikhathini esizayo, zithuthukise ukuphepha komgwaqo.
Uma unesifiso sezibani zomgwaqo omkhulu, wamukelekile ukuxhumana noTIANXIANG kuthola ikhotheshini.
