LED lights can be found in many products that are used every day. LED lights are energy-efficient and produce almost no heat in comparison to incandescent and fluorescent lights.
History
The LED light was invented by Nick Holonyak in 1962 while working for General Electric as a scientist. Holonyak is also credited with inventing the laser diode and has over 41 patents.
What Does LED Stand For?
LED stands for light-emitting diode. A diode is an electronic component that allows current to flow in only one direction.
Uses
LEDs can be found in many household devices, from computers to remote controls. Recently, LEDs have seen use in flashlights and even as a replacement for incandescent lights and Christmas lights.
How Do LEDs Work?
LEDs work by passing an electrical current over a semiconductor chip. This causes the chip to emit a photon or beam of light. The chip is often made out of arsenic, phosphorous or gallium.
Future
LED lights will definitely be in many of the products of the future. As the technology and brightness of LED lights increase, it is possible that LED lights will replace halogen headlights in cars.
