DEFINITIONO dioda emitatoare de lumina (LED) este un dispozitiv semiconductor care emite lumina vizibila atunci cand este conectat la o sursa de curent continuu (DC). Aceasta lumina este creata prin emiterea de energie eliberata de electroni in timpul recombinarii cu donorii. Avand in vedere structura semiconductoare, LED-ul are un anod si un terminal catodic. Prin urmare, trebuie respectata polaritatea corecta a tensiunii (Anod +, Catod -). LED-urile se caracterizeaza printr-o cadere de tensiune. Caderea de tensiune variaza in functie de diferitele culori ale LED-urilor, care sunt intre 1,5 - 3,5 V. Pe baza materialului diodei, lumina emisa are o lungime de unda specifica si deci o culoare particulara.
