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, automotive systems, industrial automation, and medical devices. The infrared emitter tube operates on the principle of emitting infrared light through a semiconductor material, which converts electrical energy into infrared radiation.

Working Principle of Infrared Emitter Tube

The working principle of an infrared emitter tube is based on the photoelectric effect. When an electric current passes through the semiconductor material, it excites the electrons, causing them to move from the valence band to the conduction band. As the electrons return to the valence band, they release energy in the form of photons, which are infrared light. The intensity of the emitted infrared radiation depends on the amount of electrical current applied to the tube.
