I-LED iwuhlobo lwesemiconductor ekhipha ukukhanya uma uyinikeza i-voltage ethile.Indlela yayo yokukhiqiza ukukhanya cishe isibani se-fluorescent nesibani sokukhipha igesi.I-LED ayinayo i-filament, futhi ukukhanya kwayo akwenziwa ukushisa kwe-filament, okungukuthi, akukhiqizi ukukhanya ngokuvumela ukuthi okwamanje kugeleze kumatheminali amabili.I-LED ikhipha amagagasi kagesi (imvamisa ephezulu kakhulu yokudlidliza), lapho la maza efinyelela ngaphezu kuka-380nm nangaphansi kuka-780nm, ubude begagasi obuphakathi nendawo buwukukhanya okubonakalayo, ukukhanya okubonakalayo okungabonwa ngamehlo omuntu.

Ama-diode akhipha ukukhanya angabuye ahlukaniswe abe ama-monochrome ajwayelekile akhipha ukukhanya, ama-diode akhanya kakhulu akhipha ukukhanya, ama-ultra-high light-emitting diode, ama-light-emitting diode ashintsha umbala, ama-flashing light-emitting diode, ama-voltage controlled. ama-diode akhipha ukukhanya, ama-infrared light-emitting diode kanye nama-negative resistance akhipha ukukhanya.

isicelo:

1. Isikhombi samandla e-AC

Inqobo nje uma isekethe ixhunywe kulayini kagesi ongu-220V/50Hz AC, i-LED izokhanya, okubonisa ukuthi amandla avuliwe.Inani lokumelana le-resistor ekhawulelayo yamanje engu-220V/IF.

2. Isibani sesikhombi sokushintsha kwe-AC

Sebenzisa i-LED njengesekhethi yamalambu okushintsha ukukhanya kwe-incandescent.Lapho iswishi inqanyulwa futhi isibani sicima, esamanje sakha iluphu ngo-R, i-LED nesibani sesibani esingu-EL, futhi i-LED iyakhanyisa, okulula ukuthi abantu bathole iswishi ebumnyameni.Ngalesi sikhathi, i-current in the loop incane kakhulu, futhi isibani sokukhanya ngeke sikhanyise.Lapho iswishi ivuliwe, isibani siyavulwa futhi i-LED iyacishwa.

3. Isibani sesikhombi sesokhethi yamandla e-AC

Isekhethi esebenzisa imibala emibili (i-cathode evamile) i-LED njengesibani senkomba sokuphuma kwe-AC.Ukunikezwa kwamandla esokhethi kulawulwa yi-switch S. Uma i-LED ebomvu ivuliwe, isokhethi alinawo amandla;uma i-LED eluhlaza ivuliwe, isokhethi inamandla.
