How do LEDs work? LEDs work on the principle of Electroluminescence. On passing a current through the diode, minority charge carriers and majority charge carriers recombine at the junction. On recombination, energy is released in the form of photons.

Thus, the LED can be operated by using high voltage as compared with Si or Ge diodes. Light-emitting diodes consume more energy than silicon or germanium diodes ...
LEDs are transducers of electricity into light. They operate in reverse of photodiodes, which convert light into electricity.
This means that an LED will pass current in its forward direction but block the flow of current in the reverse direction. Light emitting diodes are made from a ...
