LEDs are diodes, which is a semiconductor device that will conduct electricity in only one direction. The device is fabricated from layers of silicon and seeded with atoms of phosphorus, germanium, arsenic or other rare-earth elements. The layers of the device are called the die and the junction between the materials is where the light is generated. The electricity enters from one side of the die and exits out the other. As the current passes through the LED device, the materials that makes up the junction react and light is emitted. Different materials and designs have different colored lights and intensities. LEDs are now bright enough to be considered for applications that traditionally use incandescent bulbs.
