Far infrared LED, also known as far infrared diode, is a type of semiconductor device that emits far infrared radiation. With the rapid development of science and technology, far infrared LED has been widely used in various fields, such as medical treatment, environmental protection, and agriculture. This article will introduce the industry of far infrared LED, including its definition, working principle, applications, and market prospects.

Definition of Far Infrared LED

Far infrared LED is a kind of semiconductor device that emits far infrared radiation. It is composed of a p-n junction, and the energy level difference between the valence band and the conduction band of the semiconductor material is relatively large. When the forward bias voltage is applied to the p-n junction, the electrons and holes in the semiconductor material are injected and recombined, emitting far infrared radiation.

Working Principle of Far Infrared LED

The working principle of far infrared LED is based on the photoelectric effect. When the forward bias voltage is applied to the p-n junction, the electrons and holes in the semiconductor material are injected and recombined. During the recombination process, part of the energy of the electrons and holes is released in the form of far infrared radiation. The far infrared radiation emitted by the far infrared LED has a longer wavelength than visible light, so it is also called far infrared light.
