What are the characteristics of LED


The characteristics of LED: 

(i) LED chip’s PN junction is biased in a forward direction.
(ii) Free charged is forced (overcome vf) into the depletion zone.
(iii) Electrons recombine with holes and some of these recombinations emit light.

(iv) The color of the light is biased on the material selection, which directly affects the forward voltage of the LED.
