This article will introduce the industry of infrared emitter tube LED, including its working principle, types, applications, and future development trends.

Working Principle of Infrared Emitter Tube LED

The infrared emitter tube LED is a semiconductor device that emits infrared light when an electric current passes through it. It consists of a semiconductor material, usually gallium arsenide (GaAs) or gallium phosphide (GaP), which has a direct bandgap. When the forward voltage is applied to the LED, electrons and holes are injected into the semiconductor material, and they recombine near the p-n junction. During the recombination process, a portion of the energy is released in the form of infrared light. The wavelength of the emitted infrared light is determined by the energy bandgap of the semiconductor material. For example, GaAs emits infrared light with a wavelength of 850 nm, while GaP emits light with a wavelength of 940 nm. The infrared emitter tube LED has a high emission efficiency, low power consumption, and long service life, making it widely used in various fields.
