How Does an IR LED 950nm Work?

An IR LED 950nm operates on the principle of the photoelectric effect. When an electric current is applied to the diode, electrons are excited and move to a higher energy level. As these electrons return to their original state, they release energy in the form of photons. In the case of an IR LED 950nm, these photons are in the infrared spectrum, with a wavelength of 950nm. The key components of an IR LED 950nm include a semiconductor material, typically gallium arsenide (GaAs), a p-n junction, and a metal contact. The semiconductor material emits infrared light when an electric current passes through it. The p-n junction ensures that the flow of electrons is controlled, allowing for efficient emission of infrared light.
