The light-emitting semiconductor material determines the LED's color, so the number of colors is infinite. As indicated by its full name â Light Emitting Diode â an LED is a diode that emits light. A diode is a device that allows current to flow in only one direction. Almost any two conductive materials will form a diode when placed in contact with each other â with a single p-n semiconductor junction between them.
