Yinto eqhelekileyo ukuba izibane ze-LED ziba mnyama njengoko zisetyenziswa. Kukho izizathu ezithathu ezinokwenza izibane ze-LED zibe luzizi:.
Qhuba yonakele
Iitshiphusi ze-LED ziyafuneka ukuba zisebenze kumbane ophantsi we-DC (ngaphantsi kwe-20V), kodwa amandla ethu ombane aqhelekileyo aphezulu ombane we-AC (220V AC). Ukuguqula amandla ombane abe ngumbane ofunekayo kwiitshiphusi ze-LED, isixhobo esibizwa ngokuba yi-"LED eqhubekayo yangoku yamandla okuqhuba" siyafuneka.
Kwithiyori, nje ukuba iiparitha zomqhubi zihambelana nebhodi ye-LED, inokuqhutyelwa ngokuqhubekayo kwaye isetyenziswe ngokuqhelekileyo. Ubume bangaphakathi bomqhubi buntsokothile, kwaye nasiphi na isixhobo (esifana ne-capacitor, isilungisi, njl.njl.) ukuba ukungasebenzi kakuhle kunokubangela utshintsho kumbane ophumayo, nto leyo enokubangela ukuba isibane sombane sibe luzizi.
Umonakalo womqhubi lolona hlobo luqhelekileyo lokungasebenzi kakuhle kwizibane zokukhanyisa ze-LED, ezinokuthi zisonjululwe ngokutshintsha umqhubi.
I-LED iphelile
I-LED ngokwayo yenziwe ngokudityaniswa kwamaso okukhanya, kwaye ukuba enye okanye inxalenye yawo ayikhanyi, ngokuqinisekileyo iya kwenza ukuba isibane siphele. Amaso esibane adla ngokudityaniswa ngothotho aze emva koko ahambelane - ke ukuba iliso elinye liyatsha, kunokubangela ukuba ibhetshi yamaso ingakhanyi.
Kukho amabala amnyama acacileyo kumphezulu weliso lesibane esitshisiweyo. Yifumane kwaye uqhagamshele ucingo kumqolo wayo kwi-short-circuit kuyo; Kungenjalo, ukutshintsha ibhalbhu ngokufaka entsha kunokusombulula ingxaki.
Ngamanye amaxesha, i-LED enye iyatshisa, inokuba yinto eyenzekayo. Ukuba ihlala itshisa, ke imiba yokuqhuba kufuneka ithathelwe ingqalelo - enye imbonakalo yokungaphumeleli kwe-drive kukutsha kwee-chips ze-LED.
Ukubola kokukhanya kwe-LED
Okubizwa ngokuba yi-light decay ibhekisela ekukhanyeni okuhlayo komzimba okhanyayo, obonakala ngakumbi kwizibane ze-incandescent kunye ne-fluorescent.
Izibane ze-LED nazo azikwazi ukukunqanda ukubola kokukhanya, kodwa izinga labo lokubola kokukhanya licotha, kwaye ngokuqhelekileyo kunzima ukubona utshintsho ngeliso lenyama. Kodwa ayinakukhutshwa ukuba ii-LED ezikumgangatho ophantsi, okanye iibhodi ze-bead ezikumgangatho ophantsi, okanye izinto ezinenjongo ezifana nokuchithwa kakubi kobushushu zinokubangela ukuba izinga lokubola kokukhanya kwe-LED likhawuleze.
