Led definition: a light emitting diode (led) is a semiconductor device that emits light when electric current flows through it. working principle of led: the working principle of led involves applying a forward bias current, which causes electrons and holes to recombine at the junction, producing light. color determination: the color of an led.
The Basic Principle Of Led Download Scientific Diagram Main article: light emitting diode physics. in a light emitting diode, the recombination of electrons and electron holes in a semiconductor produces light (be it infrared, visible or uv), a process called " electroluminescence ". the wavelength of the light depends on the energy band gap of the semiconductors used. This in principle should work, the only issue being to reach the technological maturity to build such highly efficient leds at various chosen wavelengths. this quest kept semiconductor researchers busy for the next decades, and eventually led to the 2014 nobel prize. download: download high res image (60kb) download: download full size image.

Theory of led operation leds are semiconductor diodes that emit light when an electrical current is applied in the forward direction of the device — an electrical voltage that is large enough for the electrons to move across the depletion region and combine with a hole on the other side to create an electron hole pair must be applied. as this. A light emitting semiconductor device a light emitting diode (led) is a semiconductor device that emits light when a forward voltage is applied to it. the fact that certain semiconductors emit light has been observed by a number of semiconductor researchers from early on.
