Light-emitting-diode (LED) is a form of electroluminescence where incoherent and narrow-spectrum light is emitted.

LED is widely used in higher power applications such as area lighting. An LED is usually a small area (less than 1 mm) light source, often with optics added to the chip to shape its radiation pattern and assist in reflection.

Presently LEDs improve today's light output. Devices with enlarged chips produce more light while maintaining proper heat and current management. These advances allow the units to generate 10 times to 20 times more light than standard indicator lights, making them a practical illumination source for lighting fixtures. Evolving into today's "Green" solution to energy efficiency and environmental safety, LEDs substantiate a viable lighting alternative.

LED-based white backlights radically reduce the cost of illuminating LCDs in instrumentation and signs.

The use of higher power LEDs as general purpose lighting sources, have the potential to replace filament bulbs, fluorescent tubes, and neon gas signs. LED has become one of the most interesting component markets in the industry.
