Okumnyama kakhuluIsibani se-LEDKulapho kuvame khona. Ukufingqa izizathu zokuba mnyama kwezibani ze-LED akukho okunye ngaphandle kwamaphuzu amathathu alandelayo.

Umonakalo womshayeli
Ubuhlalu bezibani ze-LED buyadingeka ukuze busebenze ku-DC low voltage (ngaphansi kuka-20V), kodwa ukunikezwa kwethu okuvamile kwe-main yi-AC high voltage (AC 220V). Ukuze uguqule i-main ibe ugesi odingekayo esibanini, udinga idivayisi ebizwa ngokuthi “i-LED constant current drive power.”
Ngokwethiyori, uma nje amapharamitha omshayeli ehambisana nohlamvu lwesibani, ugesi ungasetshenziswa njalo futhi usetshenziswe ngokujwayelekile. Izangaphakathi zedrayivu ziyinkimbinkimbi, futhi noma iyiphi idivayisi (njenge-capacitors, ama-rectifier, njll.) ingabangela ushintsho ku-voltage yokuphuma, okungabangela ukuthi isibani sibe mnyama.

I-LED ishisiwe
I-LED ngokwayo yakhiwe ngohlamvu olulodwa lwesibani. Uma olulodwa noma ingxenye yalo ingakhanyiswanga, nakanjani izokwenza yonke into ibe mnyama. Uhlamvu lwesibani luvame ukuxhumeka ngochungechunge bese luhambisana - ngakho uma uhlamvu oluthile lwesibani luvutha, lungabangela ukuthi uhlamvu oluthile lwesibani lucime.
Ngemva kokusha, ubuso bebhere lesibani bunamabala amnyama asobala. Buthole, sebenzisa ucingo ukuze uluxhume ngemuva kwesibani, ulufinyeze, noma ulufake esikhundleni sebhere lesibani elisha.

Ukubola kokukhanya kwe-LED
Okubizwa ngokuthi ukubola kokukhanya ukuthi ukukhanya kwesibani kuya ngokuya kwehla – lesi simo sibonakala kakhulu ezibanini ze-incandescent kanye ne-fluorescent.
Izibani ze-LED azikwazi ukugwema ukubola kokukhanya, kodwa izinga lokubola kokukhanya lihamba kancane, kunzima ukubona izinguquko ngeso lenyama. Kodwa-ke, aziwasusi ama-LED aphansi, noma ama-bead okukhanya aphansi, noma ngenxa yezici eziqondile njengokushabalalisa ukushisa okubi, okuholela ekuboleni kokukhanya kwe-LED ngokushesha.
