Kutheni izibane ezikhokelayo ziba mnyama?

Yinto eqhelekileyo ukuba izibane ze-LED ziba luzizi xa zisetyenziswa.Ukushwankathela, kukho izizathu ezithathu zokuba kutheni izibane ze-LED zinokufiphala.

Qhuba ukusilela.

Iimfuno zesibane sesibane se-LED kumbane ophantsi we-DC (ngaphantsi kwe-20V) zisebenza, kodwa iinqununu zethu eziqhelekileyo yi-AC ephezulu yombane (AC 220V).Umbane ofunekayo ukujika umbane oyintloko ube liso lesibane ufuna isixhobo esibizwa ngokuba yi- “LED constant current drive power supply”.

Ukuthetha ngokwethiyori, nje ukuba iiparamitha zomqhubi kunye nebhodi ye-bead ihambelana, inokuqhubeka namandla, ukusetyenziswa okuqhelekileyo.Ingaphakathi lomqhubi linzima ngakumbi.Ukusilela kwaso nasiphi na isixhobo (njenge-capacitor, i-rectifier, njl.)

Ukuvutha kwe-LED.

I-LED ngokwayo iqulunqwe ngokudityaniswa kwezibane zesibane, ukuba enye okanye inxalenye yokukhanya ayikhanyisi, ibophelelekile ukwenza isibane simnyama.Amaso isibane ngokubanzi ziqhagamshelwe kuthotho kwaye emva koko ngokunxuseneyo - ngoko ke bead isibane watshisa, kunokwenzeka ukuba kubangele inani amaso isibane azikhanyisi.

Kukho amabala amnyama acacileyo kumphezulu weliso lesibane esitshisiweyo.Yifumane kwaye uyidibanise ngocingo emqolo ukuya kwi-short-circuit kuyo.Okanye buyisela intsimbi yesibane entsha, inokusombulula ingxaki.

I-LED ngamaxesha athile yayitshisa enye, mhlawumbi ngengozi.Ukuba utshisa rhoqo, kufuneka ucinge ngeengxaki zomqhubi - enye ibonakaliso yokungaphumeleli komqhubi kukutshisa i-bead.

Ukukhanya kwe-LED.

Ukubola kokukhanya kuxa ukukhanya kokukhanya kuyancipha kwaye kuncinci - imeko ecacileyo ngakumbi kwizibane ze-incandescent kunye ne-fluorescent.

Izibane ze-LED azikwazi ukukunqanda ukubola kokukhanya, kodwa isantya sayo sokubola sincinci, ngokubanzi ngeliso lenyama kunzima ukubona utshintsho.Kodwa ayibandakanyi i-LED engaphantsi, okanye ibhodi ye-bead ephantsi, okanye ngenxa yokutshatyalaliswa kobushushu kunye nezinye izinto ezijoliswe kuyo, okukhokelela ekunciphiseni ukukhanya kwe-LED kuba ngokukhawuleza.
