LED

An LED (Light Emitting Diode) is a semiconductor device that emits light when Current flows through it.

Definition

LEDs are diodes that convert electrical energy into light. They require a forward Voltage to operate and must be used with a Current-limiting Resistor.

Key Points

  • Requires forward Voltage (typically 1.8-3.3V)
  • Current must be limited (usually 10-20mA)
  • Polarity matters - anode and cathode
