I-LED luhlobo lwe-semiconductor ekhupha ukukhanya xa unika amandla ombane.Indlela yayo yokuvelisa ukukhanya phantse isibane se-fluorescent kunye nesibane sokukhutshwa kwegesi.I-LED ayinayo i-filament, kwaye ukukhanya kwayo akuveliswanga ngokufudumeza kwe-filament, oko kukuthi, ayivelisi ukukhanya ngokuvumela ukuba i-current ihambe kwii-terminals ezimbini.I-LED ikhupha amaza e-electromagnetic (isantya esiphezulu kakhulu sokungcangcazela), xa la maza efikelela ngaphezu kwe-380nm nangaphantsi kwe-780nm, ubude obuphakathi bubonakala kukukhanya okubonakalayo, ukukhanya okubonakalayo kunokubonwa ngamehlo abantu.

Iidaydi ezikhupha ukukhanya zinokwahlulwa ngokwesiqhelo zemonochrome ezikhupha ukukhanya, ukukhanya okukhazimlayo, ukukhanya okuphezulu kakhulu, ukukhanya okukhupha umbala, ukukhanya okukhanyayo, umbane olawulwayo. iidiode ezikhupha ukukhanya, i-infrared light-emitting diodes kunye ne-negative resistance-emitting diodes.

isicelo:

1. Isalathisi samandla e-AC

Ngethuba nje isiphaluka siqhagamshelwe kumgca we-220V / 50Hz AC wonikezelo lwamandla, i-LED iya kukhanyiswa, ebonisa ukuba amandla avuliwe.Ixabiso lokuchasana le-resistor yokukhawulela yangoku yi-220V / IF.

2. Ukukhanya kwesalathisi se-AC

Sebenzisa i-LED njengesekethe kwizibane ze-incandescent zokutshintsha ukukhanya.Xa i-switch inqanyuliwe kwaye i-bulb yokukhanya iphuma, i-current yenza i-loop nge-R, i-LED kunye ne-bulb yokukhanya i-EL, kunye ne-LED ikhanyisa, ekulungele ukuba abantu bafumane utshintsho ebumnyameni.Ngeli xesha, i-current in loop incinci kakhulu, kwaye i-bulb yokukhanya ayiyi kukhanyisa.Xa utshintsho luvuliwe, i-bulb ivuliwe kwaye i-LED icinyiwe.

3. Isalathisi sombane we-AC ukukhanya

Isekethe esebenzisa imibala emibini (i-cathode eqhelekileyo) i-LED njengesalathisi sokukhanya kwe-AC outlet.Ukunikezelwa kwamandla kwi-socket kulawulwa ngukutshintsha S. Xa i-LED ebomvu ivuliwe, i-socket ayinawo amandla;xa i-LED eluhlaza ivuliwe, i-socket inamandla.
