What is White LEDs
Published:2014-01-28

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.

Technical advances have dramatically improved the reliability and the performance of the LEDs since they were invented in the 1960’s. The lifetime for the new generation of LEDs is around 100,000 hours of use, or 30 to 40 years of normal operation. Because they are a semiconductor device, they are also very rugged and are not subject to fail when dropped or vibrated, as do incandescent and fluorescent lights.

The original LEDs only emitted light of one frequency or color of light. These were blues, greens, yellows, oranges or reds and they were unsuited for domestic lighting. Recent innovations in materials, doping and die structure have developed high brightness LEDs that emit light in all visible frequencies to produce white light.
