LED infrared, or infrared LED, is a type of light-emitting diode that emits infrared light. This technology has been widely used in various fields due to its excellent performance and energy-saving features. This article will introduce the industry of LED infrared, including its working principle, application fields, market status, and future development trends.

Working Principle of LED Infrared

The working principle of LED infrared is based on the photoelectric effect. When a forward voltage is applied to the diode, electrons and holes are separated in the P-N junction, and when they recombine, infrared light is emitted. The color of the emitted light depends on the band gap of the material used in the diode. The infrared light emitted by LED infrared is invisible to the human eye, but it can be detected by sensors and other devices.
