Ngokuthuthuka okuqhubekayo kwesayensi nobuchwepheshe, izibani ze-LED seziphenduke imikhiqizo evamile embonini yokukhanyisa yesimanje. Amalambu e-LED anezinzuzo zokukhanya okuphezulu, ukusetshenziswa kwamandla aphansi, impilo ende, njll., futhi abe yisinqumo sokuqala ekuphileni kokukhanyisa kwabantu. Kodwa-ke, kunezici eziningi ezithinta ukusebenza kahle okukhanyayo kwezibani ze-LED, futhi sizoxoxa ngazo ngamunye ngamunye.
Okokuqala, ikhwalithi ye-chip ye-LED ingenye yezinto ezibaluleke kakhulu ezithinta ukukhanya kwezibani ze-LED. Izinga le-LED chips lithinta ngqo ukukhanya nempilo yezibani ze-LED. Ama-chips e-LED amahle angahlinzeka ngokusebenza kahle kokukhanya okuphezulu, kuyilapho izinga eliphansi le-LED chips lizokwenza izibani ze-LED zibe nokusebenza kahle kokukhanya, ukukhanya okwanele, ukuphila okufushane nezinye izinkinga. Ngakho-ke, lapho sikhetha izibani ze-LED, kufanele sikhethe ikhwalithi enhle ye-chip ye-LED ukuze siqinisekise ukusebenza kahle kokukhanya kwezibani ze-LED.
Okwesibili, idizayini yokukhipha ukushisa nayo iyisici esibalulekile esithinta ukusebenza kahle kokukhanya kwezibani ze-LED. Izibani ze-LED zizokhiqiza ukushisa okuningi emsebenzini, uma kungenjalo ukuchithwa kokushisa okufika ngesikhathi, kuzoholela ekunciphiseni ukuphila kwesibani, ukwehla kokusebenza kahle kokukhanya nezinye izinkinga. Ngakho-ke, umklamo omuhle wokushisa ukushisa uyadingeka kakhulu. Manje izibani ze-LED ngokuvamile zisebenzisa i-aluminium yokushisa ukushisa ukuklama, le nto ine-conductivity enhle yokushisa, ingakwazi ukuqeda ukushisa ngokuphumelelayo, ukuqinisekisa ukuphila kwezibani ze-LED nokusebenza kahle kokukhanya.
Idizayini ye-Optical nayo iyisici esibalulekile esithinta ukusebenza kahle kokukhanya kwezibani ze-LED. Umklamo omuhle we-optical uvumela ukukhanya kwesibani ukuthi kukhanye ngokulinganayo endaweni okuhlosiwe, ukuthuthukisa ukusebenza kahle kokukhanya. Umklamo ompofu we-optical uzoholela ekukhanyeni okungalingani kwezibani ze-LED, ukhiqize ukukhanya okunamandla, okuthinta imiphumela yokubuka yabantu. Ngakho-ke, lapho ukhetha izibani ze-LED, kuyadingeka ukukhetha umklamo omuhle we-optical ukuqinisekisa ukusebenza kahle kokukhanya kwezibani kanye nemiphumela yokubuka yabantu.
Umjikelezo wokushayela nawo ungenye yezinto ezithinta ukusebenza kahle okukhanyayo kwamalambu e-LED. Umjikelezo omuhle wokushayela ungathuthukisa ukukhanya nempilo ye-LED, kanti izinga eliphansi lesekethe yedrayivu lizoholela empilweni yesibani se-LED, ukwehla kokukhanya nezinye izinkinga. Ngakho-ke, lapho ukhetha izibani ze-LED, kubalulekile ukukhetha umjikelezo omuhle wokushayela ukuze uqinisekise ukusebenza kahle okukhanyayo nokuphila kwezibani ze-LED.
Okokugcina, ukusetshenziswa kwendawo yokukhanyisa kuzophinde kuthinte ukusebenza kahle kokukhanya kwezibani ze-LED. Njengokushisa, umswakama, uthuli nezinye izici zizothinta ukusebenza kahle kokukhanya kwezibani ze-LED. Lapho ukhetha izibani ze-LED, kuyadingeka ukukhetha izibani ze-LED ezifanele ngokusho kokusetshenziswa kwendawo ukuze kuqinisekiswe ukusebenza kahle kokukhanya nokuphila kwezibani.
Kafushane, kunezici eziningi ezithinta ukusebenza kahle okukhanyayo kwezibani ze-LED, okuhlanganisa ikhwalithi yama-chips e-LED, idizayini yokukhipha ukushisa, i-optical design, i-drive circuit kanye nemvelo yokusebenzisa. Lapho sikhetha izibani ze-LED, kufanele sicabangele lezi zici ngokucophelela futhi sikhethe izibani ze-LED ezinekhwalithi enhle nokusebenza okuhle kakhulu ukuze siqinisekise ukusebenza kahle okukhanyayo nokuphila kwezibani.
