Working Principles of Infrared Beam Diode

An infrared beam diode, also known as an infrared LED (Light Emitting Diode), operates on the principle of emitting infrared light when an electric current passes through it. The diode consists of a semiconductor material, typically gallium arsenide (GaAs) or gallium nitride (GaN), which emits infrared radiation when excited by an electric current. The emitted light is then focused into a narrow beam using a lens or mirror, enabling precise targeting and efficient transmission.

The key components of an infrared beam diode include:

1. Semiconductor material: The semiconductor material acts as the active region where the electron-hole pairs are generated, leading to the emission of infrared light.
2. P-N junction: The P-N junction is formed at the interface between the P-type and N-type semiconductor materials, creating a potential barrier that controls the flow of electrons and holes.
3. Encapsulation: The encapsulation protects the diode from external factors such as moisture, dust, and physical damage.
4. Lens or mirror: The lens or mirror focuses the emitted infrared light into a narrow beam, enhancing its directivity.
