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 gapof the semiconductors used.

4 dni temu · How LED Lights Work LED lights function using a simple mechanism involving two key components: a semiconductor and a current of electricity. Here's a more detailed look at how this works: 1. The Semiconductor LED lights use a semiconductor material that has two layers: the p-type and the n-type. The p-type is positively charged, while the n ...

Stated very simply, an LED produces light when an electrical current passes through a microchip, which illuminates the tiny light sources called LEDs and the result is visible light. For a complete explanation, see How Light Emitting Diodes Work.
24 lut 2012 · How Does a Light Emitting Diode (LED) Work? When the forward biased current I F is applied through the p-n junction of the diode , minority carrier electrons are injected into the p-region and corresponding minority carrier electrons are injected into the n-region.
