Working Principle of Infrared LEDs

Infrared LEDs operate based on the principle of semiconductor physics. These devices are made up of a p-n junction, where the p-type and n-type semiconductor materials are combined. When an electric current is applied to the junction, electrons from the n-type material move towards the p-type material, releasing energy in the form of photons. These photons fall within the infrared spectrum, which is characterized by wavelengths longer than visible light. The 5mm size of these LEDs makes them highly compact and energy-efficient. They can be easily integrated into various devices and systems, making them a preferred choice for numerous applications. The working principle of infrared LEDs is based on the following key components: 1. Emitter: The emitter is the semiconductor material that emits infrared light when an electric current is applied. It is typically made up of gallium arsenide (GaAs) or indium gallium arsenide (InGaAs). 2. Lens: The lens focuses the emitted infrared light into a narrow beam, enhancing its intensity and directing it towards the intended target. 3. Encapsulation: The encapsulation material provides protection to the internal components of the LED and ensures efficient light emission. 4.
