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.
