Introduction to Infrared Emitter Tube LED

Background and Definition

Infrared emitter tube LED, also known as infrared LED, is a type of light-emitting diode that emits infrared light. It is widely used in various fields such as consumer electronics, automotive, medical, and industrial applications. Unlike visible light, infrared light is not visible to the human eye, but it can be detected by sensors and other devices. The infrared emitter tube LED has become an essential component in modern technology due to its high efficiency, low power consumption, and compact size.

Working Principle

The working principle of an infrared emitter tube LED is based on the semiconductor material, typically gallium arsenide (GaAs) or aluminum gallium arsenide (AlGaAs). When an electric current is applied to the diode, electrons and holes are injected into the semiconductor material. As the electrons and holes recombine, they release energy in the form of photons. These photons have a longer wavelength than visible light, resulting in infrared light emission. The infrared emitter tube LED consists of a semiconductor chip, a lens, and a package. The semiconductor chip is the core of the LED, where the light is generated. The lens focuses the emitted light into a narrow beam, enhancing the intensity and directionality of the infrared light. The package protects the semiconductor chip and provides electrical connections.
