Okumnyama kakhuluUkukhanya kwe-LEDukuthi, kuvame kakhulu.Ukufingqa izizathu zokuba mnyama kwezibani ze-LED akuyona into engaphezu kwamaphuzu amathathu alandelayo.

Ukulimala komshayeli
Ubuhlalu besibani se-LED buyadingeka ukuze kusebenze ku-DC low voltage (ngaphansi kuka-20V), kodwa ukunikezwa kwethu okujwayelekile kwamapayipi ama-AC high voltage (AC 220V).Ukuze uvule amapayipi amakhulu abe ugesi odingekayo esibanini, udinga idivayisi ebizwa ngokuthi "i-LED constant current drive power."
Ngokombono, inqobo nje uma imingcele yomshayeli ifanisa ubuhlalu besibani, ukunikezwa kwamandla kungasetshenziswa ngokuqhubekayo futhi kusetshenziswe ngokujwayelekile.Izinto zangaphakathi zedrayivu ziyinkimbinkimbi, futhi noma iyiphi idivayisi (njengama-capacitor, ama-rectifiers, njll.) ingase ibangele ushintsho ku-voltage okukhiphayo, okungabangela isibani sibe mnyama.

I-LED ishile
I-LED ngokwayo yakhiwe ngobuhlalu besibani obubodwa.Uma eyodwa noma ingxenye yayo ingakhanyiswanga, nakanjani izokwenza yonke into ibe mnyama.Ubuhlalu besibani ngokuvamile buxhunywa ngochungechunge bese ngokuhambisana - ngakho uma ubuhlalu besibani obuthile buvutha, bungase bubangele ukuthi inqwaba yobuhlalu bamalambu bucinywe.
Ngemva kokuvutha, ubuso bobuhlalu besibani buba namabala amnyama asobala.Yithole, sebenzisa intambo ukuze uyixhume ngemuva kwesibani, uyifinyeze, noma ubeke ubuhlalu besibani esisha esikhundleni sayo.

Ukubola kokukhanya kwe-LED
Okubizwa ngokuthi ukubola kokukhanya ukuthi ukukhanya kwe-illuminant kuya phansi futhi kuyancipha - lesi simo sibonakala ngokucacile kumalambu e-incandescent kanye ne-fluorescent.
Izibani ze-LED azikwazi ukugwema ukubola kokukhanya, kodwa izinga layo lokubola kokukhanya lihamba kancane, kunzima ukubona izinguquko ngeso lenyama.Kodwa-ke, ayikhiphi ama-LED aphansi, noma ubuhlalu bokukhanya obuphansi, noma ngenxa yezinto ezihlosiwe ezifana nokungashisi kahle ukushisa, okuholela ekuboleni kokukhanya kwe-LED ngokushesha.
