Yinto eqhelekileyo ukuba izibane ze-LED ziyancipha ngakumbi xa zisetyenziswa. Ngamafutshane, kukho izizathu ezintathu zokuba izibane ze-LED zinciphe.

Ukungaphumeleli kweDrive.

Iimfuneko zeentsimbi zezibane ze-LED kwi-DC low voltage (ngaphantsi kwe-20V) ziyasebenza, kodwa iintsimbi zethu eziqhelekileyo ze-AC yi-AC high voltage (AC 220V). Umbane ofunekayo ukuguqula umbane we-mains ube yintsimbi yezibane ufuna isixhobo esibizwa ngokuba yi-"LED constant current drive power supply".

Ngokwethiyori, lo gama nje iiparameter zomqhubi kunye nebhodi yeentsimbi zihambelana, zinokuqhubeka nokusebenza ngendlela eqhelekileyo. Ingaphakathi lomqhubi liyinkimbinkimbi ngakumbi. Ukusilela kwaso nasiphi na isixhobo (esifana ne-capacitor, i-rectifier, njl.njl.) kunokubangela utshintsho kwi-output voltage, nto leyo eya kubangela ukufiphala kwesibane.

Ukutsha kwe-LED.

I-LED ngokwayo yenziwe ngokudibanisa iibhere zezibane, ukuba enye okanye inxalenye yokukhanya ayikhanyi, inyanzeliswa ukuba isibane sonke sibe mnyama. Iibhere zezibane zihlala ziqhagamshelwe ngochungechunge kwaye emva koko ziqhagamshelwe ngaxeshanye - ngoko ke xa ibhere yezibane itshisiwe, kunokwenzeka ukuba inani leebhere zezibane zingakhanyi.

Kukho amabala amnyama acacileyo kumphezulu we-lamp bead etshisiweyo. Yifumane uze uyidibanise ngocingo emqolo ukuze uyifinyeze. Okanye utshintshe i-lamp bead entsha, ingasombulula ingxaki.

I-LED yayitshisa enye ngamanye amaxesha, mhlawumbi ngengozi. Ukuba utshisa rhoqo, kufuneka uqwalasele iingxaki zomqhubi — enye into ebonisa ukungaphumeleli komqhubi kukutsha kwentsimbi.

Ukufiphala kwe-LED.

Ukubola kokukhanya kuxa ukukhanya kokukhanya kuncipha kancinci kancinci — imeko ebonakala ngakumbi kwizibane ze-incandescent kunye nezibane ze-fluorescent.

Izibane ze-LED azikwazi ukuphepha ukubola kokukhanya, kodwa isantya sazo sokubola kokukhanya sicotha kakhulu, ngokubanzi ngeliso lenyama kunzima ukubona utshintsho. Kodwa ayikhuphi i-LED engaphantsi, okanye ibhodi ye-bead yokukhanya engaphantsi, okanye ngenxa yokungasasazeki kakuhle kobushushu kunye nezinye izinto ezijolise ekufezekiseni iinjongo, nto leyo ebangela ukuba isantya sokuncipha kokukhanya kwe-LED sibe sikhawuleza.
