Infrared emitter tube LED, or infrared emitting diode, is a type of semiconductor device that emits infrared radiation when an electric current is applied. This technology has found extensive applications in various fields, such as remote control, communication, and medical diagnosis. In this article, we will introduce the industry of infrared emitter tube LED, covering its working principle, market trends, and future development.

Working Principle of Infrared Emitter Tube LED

The infrared emitter tube LED is a semiconductor device that utilizes the principle of electroluminescence. When an electric current is applied to the device, electrons and holes in the semiconductor material recombine, releasing energy in the form of photons. In the case of infrared emitter tube LED, the photons emitted have a longer wavelength, which corresponds to the infrared region of the electromagnetic spectrum. The semiconductor material used in the infrared emitter tube LED is typically a compound semiconductor, such as gallium arsenide (GaAs) or indium gallium arsenide (InGaAs). These materials have a direct bandgap, which allows for efficient emission of infrared radiation. The structure of the infrared emitter tube LED typically consists of a p-n junction, with the p-type material on the anode and the n-type material on the cathode. When the electric current flows through the p-n junction, electrons and holes are separated, creating a depletion region. As the electrons move towards the cathode, they collide with the crystal lattice, releasing energy in the form of infrared photons. The infrared radiation emitted from the device is then focused by a lens or an optical fiber to achieve a higher intensity and a specific beam pattern.
