LED ndi semiconductor chipangizo, amene ali mfundo zotsatirazi:
Ma diode owunikira: Ma electron mkati mwa LED akabayidwa mu P -type semiconductor crystal, ma elekitironi ndi ma cavities amapanga composite effect ndikupanga ma photons.
 
Ntchito: LED imatha kupeza mitundu yowala yowala komanso yowala kudzera muukadaulo wosinthira.
 
Kuwongolera: LED imatha kuwongolera magawo monga mtundu wonyezimira ndi kuwala kudzera mumagetsi owongolera, apano ndi njira zina.
