LED bụ ngwaọrụ semiconductor, nke nwere ụkpụrụ ndị a:
Diodes na-enwu ọkụ: Mgbe a na-agbanye electrons n'ime LED n'ime kristal P-type semiconductor, electrons na cavities ga-eme ka ọ bụrụ ihe mgbagwoju anya ma mepụta photons.
 
Ozi: LED nwere ike nweta agba na nchapụta dị iche iche site na teknụzụ modulation.
 
Njikwa: LED nwere ike ijikwa paramita dị ka agba na-egbuke egbuke na nchapụta site na voltaji njikwa, ugbu a na ụzọ ndị ọzọ.
