Introduction to Infrared Emitter Tube

What is an Infrared Emitter Tube?

An infrared emitter tube, also known as an infrared diode or LED, is an electronic device that emits infrared radiation when an electric current is applied to it. These devices are widely used in various applications, including consumer electronics, industrial automation, medical devices, and security systems. The infrared emitter tube operates on the principle of converting electrical energy into infrared light, which is a form of electromagnetic radiation with longer wavelengths than visible light but shorter than microwave radiation.

Working Principle

The working principle of an infrared emitter tube is based on the semiconductor material, typically made of gallium arsenide (GaAs) or indium gallium arsenide (InGaAs). When a voltage is applied across the semiconductor material, electrons and holes are excited, and when they recombine, they release energy in the form of infrared light. The wavelength of the emitted light can be controlled by the composition and structure of the semiconductor material.
