Okukhona kumnyama ngakumbiIsibane se-LEDOkukhona ixhaphake kakhulu. Ukushwankathela izizathu zokuba izibane ze-LED zibe mnyama akukho nto ingaphezulu kwala manqaku mathathu alandelayo.

Umonakalo womqhubi
Iintsimbi zezibane ze-LED ziyafuneka ukuze zisebenze kwi-DC low voltage (ngaphantsi kwe-20V), kodwa umbane wethu oqhelekileyo yi-AC high voltage (AC 220V). Ukuze uguqule i-mains ibe ngumbane ofunekayo kwisibane, udinga isixhobo esibizwa ngokuba yi-“LED constant current drive power.”
Ngokwethiyori, logama nje iiparameter zomqhubi zihambelana ne-lamp bead, umbane ungasetyenziswa rhoqo kwaye usetyenziswe ngokuqhelekileyo. Izinto zangaphakathi ze-drive ziyinkimbinkimbi, kwaye nasiphi na isixhobo (ezifana nee-capacitors, ii-rectifiers, njl.njl.) sinokubangela utshintsho kwi-output voltage, nto leyo enokubangela ukuba isibane sibe mnyama.

I-LED itshisiwe
I-LED ngokwayo yenziwe ngentsimbi yesibane enye. Ukuba enye okanye inxalenye yayo ayikhanyiswanga, ngokuqinisekileyo iya kwenza yonke into ibe mnyama. Iintsimbi zesibane zihlala ziqhagamshelwe ngolandelelwano kwaye emva koko ziqhagamshelwe ngaxeshanye - ngoko ke ukuba intsimbi ethile yesibane iyatsha, inokubangela ukuba iqela leentsimbi zesibane licime.
Emva kokutsha, umphezulu wentsimbi yesibane unamabala amnyama acacileyo. Yifumane, sebenzisa ucingo ukuyiqhagamshela ngasemva kwesibane, uyifinyeze, okanye uyitshintshe ngentsimbi entsha yesibane.

Ukubola kokukhanya kwe-LED
Oko kubizwa ngokuba kukubola kokukhanya kukuba ukukhanya kwesibane kuya kuncipha ngakumbi – le meko ibonakala ngakumbi kwizibane ze-incandescent kunye nezibane ze-fluorescent.
Izibane ze-LED azinakukuphepha ukubola kokukhanya, kodwa izinga lokubola kokukhanya licotha kakhulu, kunzima ukubona utshintsho ngeliso lenyama. Nangona kunjalo, ayizithinteli ii-LED ezingaphantsi, okanye ii-beads zokukhanya ezingaphantsi, okanye ngenxa yezinto ezibonakala ngathi azikho nzulu njengokusasazwa kakuhle kobushushu, nto leyo ebangela ukubola kokukhanya kwe-LED ngokukhawuleza.
