Infrared Emitter Tube: An Essential Component in Modern Technology

The infrared emitter tube, also known as an infrared diode, is an essential component in modern technology, particularly in the field of infrared communication and remote control. As the name suggests, it emits infrared radiation, which is a form of electromagnetic radiation with wavelengths longer than those of visible light but shorter than those of microwaves. This article aims to provide an in-depth introduction to the infrared emitter tube, covering its working principle, applications, and the industry trends.

Working Principle of Infrared Emitter Tube

The infrared emitter tube operates on the principle of semiconductor physics. It consists of a semiconductor material, usually gallium arsenide (GaAs) or gallium nitride (GaN), which is sandwiched between two electrodes. When a forward voltage is applied across the electrodes, electrons and holes recombine in the semiconductor material, releasing energy in the form of photons. These photons have wavelengths within the infrared region of the electromagnetic spectrum. The infrared emitter tube is a two-terminal device, with one terminal being the anode and the other being the cathode. When a positive voltage is applied to the anode and a negative voltage to the cathode, the device emits infrared radiation. The intensity and wavelength of the emitted radiation depend on the material, temperature, and forward voltage applied to the tube.
