A light-emitting diode LED is a semiconductor light source that emits light when current flows through it. Electrons in the semiconductor recombine with electron holes , releasing energy in the form of photons. The color of the light corresponding to the energy of the photons is determined by the energy required for electrons to cross the band gap of the semiconductor. Appearing as practical electronic components in , the earliest LEDs emitted low-intensity infrared light. The first visible-light LEDs were of low intensity and limited to red. Modern LEDs are available across the visible , ultraviolet , and infrared wavelengths, with high light output.
