NettetA light-emitting diode ( LED) is a semiconductor device that emits light when current flows through it. Electrons in the semiconductor recombine with electron holes, releasing energy in the form of photons. NettetDiodes and LEDs Diodes Diodes are two-terminal semiconductor devices that conduct … NettetFor an LED to work it needs to be connected to a voltage source with the correct side. The voltage supply side of the diode is the positive (+) side, this is called the anode. The negative side is called the cathode. Because diodes are made of semiconductor material, they have a very specific voltage where they will turn on. shockwave vfx
