Infrared emitter tube LED, also known as infrared LED, is a type of semiconductor light-emitting device that emits infrared light. As a key component in various applications, such as remote control, surveillance, and communication, infrared emitter tube LED has become an indispensable part of modern life. This article will introduce the industry of infrared emitter tube LED, including its working principle, types, applications, and market trends.

Working Principle of Infrared Emitter Tube LED

The infrared emitter tube LED is a semiconductor device, which is composed of a p-n junction. When the forward voltage is applied to the p-n junction, electrons and holes are injected into the junction, and the recombination of electrons and holes will produce infrared light. The wavelength of the emitted light is between 700nm and 3000nm, which is in the infrared region of the electromagnetic spectrum. The working principle of the infrared emitter tube LED is based on the principle of energy band theory. In the semiconductor material, the conduction band and the valence band are separated by a certain energy gap. When the forward voltage is applied, electrons from the conduction band will be injected into the valence band, and the recombination of electrons and holes will produce infrared light. The energy gap of the semiconductor material determines the wavelength of the emitted light.
