Yinto eqhelekileyo ukuba izibane ezikhokelwayo zibe mnyama kwaye zibe mnyama njengoko zisetyenziswa. Shwankathela izizathu ezinokwenza kube mnyamaUkukhanya kwe-LED, engeyonto ngaphandle kwezi ngongoma zintathu zilandelayo.

1.Drive yonakele

Amaso isibane se-LED kufuneka asebenze kumbane ophantsi we-DC (ngaphantsi kwe-20V), kodwa amandla ethu ombane aqhelekileyo yi-AC ephezulu yombane (AC 220V). Ukuguqula umbane oyintloko kumandla afunwa ngamaso esibane, sifuna isixhobo esibizwa ngokuba yi-"LED constant current current driving power supply".

Ngokwethiyori, nje ukuba iiparamitha zomqhubi zihambelana nepleyiti yesibane yesibane, inokuqhutywa ngokuqhubekayo kwaye isetyenziswe ngokuqhelekileyo. Ingaphakathi lomqhubi linzima. Ukusilela kwaso nasiphi na isixhobo (esifana ne-capacitor, isilungisi, njl.njl.) kunokubangela utshintsho lombane ophumayo, kwaye emva koko kubangele ukuba isibane sibe luzizi.

Umonakalo womqhubi yimpazamo eqhelekileyo kwizibane ze-LED. Ngokuqhelekileyo inokusombulula emva kokutshintsha umqhubi.

2.Led itshiswe

I-LED ngokwayo iqulunqwe ngamaso wesibane enye enye. Ukuba enye okanye inxalenye yazo ayivuswanga, oko kuya kusenza mnyama sonke isibane. Amaso esibane adla ngokudityaniswa kuthotho kwaye emva koko ahambelane - ke ukuba intsimbi yesibane itshisiwe, ibhetshi yamaso esibane ayinakukhanya.

Kukho amabala amnyama acacileyo kumphezulu weliso lesibane esitshisiweyo. Yifumane, uyidibanise ngasemva ngocingo kunye nesiphaluka esifutshane; Okanye intsimbi yesibane entsha inokusombulula ingxaki.

Ikhokelwe ngamaxesha athile itshiswe enye, inokuba ngamabona-ndenzile. Ukuba utshisa rhoqo, kufuneka uqwalasele ingxaki ye-drive - enye ibonakaliso yokungaphumeleli kwe-drive kutshisa ubuhlalu besibane.

3.Ukunciphisa ukukhanya kwe-LED

Okubizwa ngokuba yi-light decay kukuba ukukhanya kokukhanya kuya kuhla kwaye kuphantsi - kubonakala ngakumbi kwizibane ze-incandescent kunye ne-fluorescent.

Isibane se-LED asikwazi ukuphepha ukubola kokukhanya, kodwa isantya saso sokubola sincinci, kwaye ngokuqhelekileyo kunzima ukubona utshintsho ngeso lenyama. Nangona kunjalo, ayithethi ukuba umgangatho ophantsi okhokelela, okanye umgangatho ophantsi we-bead plate, okanye ngenxa yezinto ezinenjongo ezifana nokuchithwa kobushushu obuphantsi, isantya sokubola kwe-LED sikhawuleza.
