product brief introduction:
A light-emitting diode (LED) is a two-lead semiconductor light
source. It is a p-n junction diode, which emits light when
activated. When a suitable voltage is applied to the leads,
electrons are able to recombine with electron holes within the
device, releasing energy in the form of photons. This effect is
called electroluminescence, and the color of the light
(corresponding to the energy of the photon) is determined by the
energy band gap of the semiconductor.
An LED is often small in area (less than 1 mm2) and integrated
optical components may be used to shape its radiation pattern.
Appearing as practical electronic components in 1962, the earliest
LEDs emitted low-intensity infrared light. Infrared LEDs are still
frequently used as transmitting elements in remote-control
circuits, such as those in remote controls for a wide variety of
consumer electronics. The first visible-light LEDs were also of low
intensity, and limited to red. Modern LEDs are available across the
visible, ultraviolet, and infrared wavelengths, with very high
brightness.
Now LEDs have allowed new text, video displays, and sensors to be
developed, while their high switching rates are also used in
advanced communications technology.
