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 is applied to it. It is widely used in various applications, such as remote controls, night vision devices, and thermal imaging cameras. The infrared emitter tube is a key component in the infrared technology industry, and its development has brought significant progress to many fields.

Working Principle of Infrared Emitter Tube

The working principle of an infrared emitter tube is based on the photoelectric effect. When a forward voltage is applied to the diode, electrons are injected into the depletion region, causing the electrons and holes to recombine. During this process, energy is released in the form of infrared radiation. The wavelength of the emitted infrared radiation depends on the material and structure of the diode.
