Introduction to Infrared Emitter Tube

What is an Infrared Emitter Tube?

An infrared emitter tube, also known as an infrared diode, is a semiconductor device that emits infrared radiation when an electric current passes through it. It is widely used in various applications, such as remote controls, infrared sensors, and thermal imaging. The infrared emitter tube operates on the principle of the photoelectric effect, where electrons are excited and released when the semiconductor material is exposed to light or heat.

Working Principle of Infrared Emitter Tube

The working principle of an infrared emitter tube is based on the photoelectric effect. When an electric current is applied to the semiconductor material, electrons are excited and move to a higher energy level. As these electrons return to their original energy level, they release energy in the form of infrared radiation. The intensity of the emitted infrared radiation depends on the voltage applied to the tube and the temperature of the semiconductor material.
