Kuyinto evamile kakhulu ukuthi izibani ze-LED ziya ngokuya zifiphala uma zisetshenziswa kakhulu. Ngamafuphi, kunezizathu ezintathu zokuthi kungani izibani ze-LED zingafiphala.

Ukwehluleka kwedrayivu.

Izidingo zobhontshisi bezibani ze-LED ku-DC low voltage (ngaphansi kuka-20V) ziyasebenza, kodwa ochwepheshe bethu abavamile yi-AC high voltage (AC 220V). Ugesi odingekayo ukuguqula amandla obhontshisi abe yi-lamp bead udinga idivayisi ebizwa ngokuthi “i-LED constant current drive power supply”.

Ngokwemfundiso, uma nje amapharamitha omshayeli kanye nebhodi lama-bead ehambisana, angaqhubeka nokusebenza ngendlela evamile. Ingaphakathi lomshayeli liyinkimbinkimbi kakhulu. Ukwehluleka kwanoma iyiphi idivayisi (njenge-capacitor, i-rectifier, njll.) kungabangela ushintsho lwe-voltage yokukhipha, okuzobangela ukufiphala kwesibani.

Ukushiswa yi-LED.

I-LED ngokwayo yakhiwe yinhlanganisela yama-lamp beads, uma eyodwa noma ingxenye yokukhanya ingakhanyi, nakanjani izokwenza lonke isibani libe mnyama. Ama-lamp beads ngokuvamile axhunywe ngokulandelana bese ehambisana - ngakho-ke uma i-lamp bead ishisiwe, kungenzeka ukuthi inani lama-lamp beads lingakhanyi.

Kukhona amabala amnyama asobala ebusweni be-lamp bead eshile. Yithole bese uyixhuma ngentambo emhlane wayo ukuze uyifinyeze. Noma ushintshe i-lamp bead entsha, ingaxazulula inkinga.

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

Ukufiphala kwe-LED.

Ukubola kokukhanya kwenzeka lapho ukukhanya kokukhanya kuncipha kancane kancane — isimo esibonakala kakhulu ezibanini ze-incandescent kanye ne-fluorescent.

Izibani ze-LED azikwazi ukugwema ukubola kokukhanya, kodwa ijubane lazo lokubola kokukhanya lihamba kancane, ngokuvamile ngeso lenyama kunzima ukubona ushintsho. Kodwa ayikhiphi i-LED ephansi, noma ibhodi le-bead yokukhanya ephansi, noma ngenxa yokushabalalisa ukushisa okubi nezinye izici eziqondile, okuholela ekutheni ijubane lokwehla kokukhanya kwe-LED liba ngokushesha.
