Kuyinto evamile kakhulu ukuthi izibani ze-LED ziba lufifi lapho zisetshenziswa kakhulu.Ukufingqa, kunezizathu ezintathu zokuthi kungani izibani ze-LED zingafiphazwa.

Ukuhluleka kweDrayivu.

Izidingo zobuhlalu besibani se-LED ku-DC low voltage (ngaphansi kuka-20V) ziyasebenza, kodwa amapayipi ethu avamile yi-AC high voltage (AC 220V).Ugesi odingekayo ukuze uguqule amandla kagesi abe ubuhlalu besibani udinga idivayisi ebizwa ngokuthi “i-LED constant current drive power supply”.

Uma sikhuluma ngokwethiyori, inqobo nje uma imingcele yomshayeli kanye nebhodi lobuhlalu, ingaqhubeka inamandla, ukusetshenziswa okuvamile.Ingaphakathi lomshayeli liyinkimbinkimbi.Ukwehluleka kwanoma iyiphi idivayisi (njenge-capacitor, i-rectifier, njll.) kungase kubangele ukuguqulwa kwe-voltage ephumayo, okuzobangela ukufiphala kwesibani.

Ukushisa kwe-LED.

I-LED ngokwayo yakhiwe inhlanganisela yobuhlalu besibani, uma eyodwa noma ingxenye yokukhanya ingakhanyi, ibophezelekile ukwenza isibani sonke sibe mnyama.Ubuhlalu besibani ngokuvamile buxhunywe kuchungechunge bese ngokuhambisana - ngakho-ke ubuhlalu besibani bushisiwe, kungenzeka ukuthi kubangele inani lezibani zezibani azikhanyi.

Kunamabala amnyama asobala ebusweni bobuhlalu besibani esishile.Yithole bese uyixhuma ngocingo emhlane ukuze uyijikeleze kancane.Noma shintsha ubuhlalu besibani obusha, kungaxazulula inkinga.

I-LED ngezikhathi ezithile yayishisa eyodwa, mhlawumbe ngengozi.Uma ushisa njalo, udinga ukucabangela izinkinga zomshayeli - okunye ukubonakaliswa kokwehluleka komshayeli ukushiswa kobuhlalu.

Ukukhanya kwe-LED.

Ukubola kokukhanya yilapho ukukhanya kokukhanya kuba kancane kancane - isimo esigqama kakhulu kumalambu e-incandescent kanye ne-fluorescent.

Izibani ze-LED azikwazi ukugwema ukubola kokukhanya, kodwa ijubane layo lokubola kokukhanya lihamba kancane, ngokuvamile ngeso lenyama kunzima ukubona ushintsho.Kodwa ayibandakanyi i-LED ephansi, noma ibhodi lobuhlalu obukhanyayo obuphansi, noma ngenxa yokungashisi kahle ukushisa nezinye izici ezihlosiwe, okuholela ekunciphiseni kokukhanya kwe-LED kuba ngokushesha.
