Lesson: Light Emitting Diodes
LED with electroluminescence are semiconductor components encased in an epoxy lens in a circuit that produce light. Anvil and post are positive and negative, respectively. When forward biased switched-on, electrons recombine with electron holes, releasing energy in the form of photons. These components are utilized in computers as indicators. LEDs are bright with a frequency range from ultraviolet through infrared. LEDs have an exponentially longer life than incandescent bulbs and consume much less energy.Check out the infinite uses of LED technology.
