Ubumnyama ngakumbiUkukhanya kwe-LEDkukuba, ixhaphake ngakumbi.Ukushwankathela izizathu zokuba mnyama kwezibane ze-LED akukho nto ngaphezu kwamanqaku amathathu alandelayo.

Umonakalo womqhubi
Amaso esibane se-LED afuneka ukuba asebenze kumbane ophantsi we-DC (ngaphantsi kwe-20V), kodwa unikezelo lwethu oluqhelekileyo olungundoqo yi-AC yombane ophezulu (AC 220V).Ukuguqula ii-mains zibe ngumbane ofunekayo kwisibane, udinga isixhobo esibizwa ngokuba "yi-LED eqhubekayo yamandla okuqhuba."
Kwithiyori, nje ukuba iiparitha zomqhubi zihambelana nentsimbi yesibane, ukunikezelwa kwamandla kungasetyenziswa ngokuqhubekayo kwaye kusetyenziswe ngokuqhelekileyo.I-internals of drive iyinkimbinkimbi, kwaye nasiphi na isixhobo (njenge-capacitors, i-rectifiers, njl.) inokubangela utshintsho kwi-voltage ephumayo, enokubangela ukuba isibane sibe mnyama.

I-LED yatshisa
I-LED ngokwayo yenziwe ngentsimbi yesibane esinye.Ukuba enye okanye inxalenye yayo ayikhanyiswanga, ngokuqinisekileyo iya kwenza yonke into ibe mnyama.Amaso esibane adityaniswa ngokubanzi kuthotho kwaye emva koko ahambelanayo - ke ukuba iliso lesibane elithile liyatsha, linokubangela ukuba ibhetshi yamaso yesibane icinywe.
Emva kokutshisa, umphezulu wentsimbi yesibane unamabala amnyama acacileyo.Yifumane, sebenzisa ucingo ukuyidibanisa ngasemva kwesibane, i-short-circuit it, okanye uyibuyisele ngentsimbi yesibane entsha.

Ukubola kokukhanya kwe-LED
Okubizwa ngokuba yi-light decay kukuba ukukhanya kwe-illuminant kuyancipha kwaye kuphantsi - le meko ibonakala ngokucacileyo kwizibane ze-incandescent kunye ne-fluorescent.
Izibane ze-LED azikwazi ukuphepha ukubola kokukhanya, kodwa izinga layo lokubola kokukhanya licotha kakhulu, kunzima ukubona utshintsho ngeliso lenyama.Nangona kunjalo, ayikuthinteli ii-LED ezingaphantsi, okanye ubuhlalu obungaphantsi kokukhanya, okanye ngenxa yezinto ezinenjongo ezifana nokuchithwa kokushisa okungahambi kakuhle, okubangelwa ukubola kokukhanya kwe-LED ngokukhawuleza.
