Introduction to Infrared LED Light

1. Definition and Basic Principles

Infrared LED light, also known as infrared diode, is a type of semiconductor light source that emits infrared radiation. It is widely used in various fields due to its unique advantages. The basic principle of infrared LED light is based on the photoelectric effect. When the forward bias voltage is applied to the semiconductor material, electrons and holes are generated, and then recombine to emit photons. These photons have a wavelength longer than visible light, so they are in the infrared spectrum.

2. Types of Infrared LED Light

According to the different wavelengths, infrared LED light can be divided into three categories: near-infrared, mid-infrared, and far-infrared. The near-infrared LED light has a wavelength range of 780nm to 1400nm, which is close to the red light in the visible spectrum. The mid-infrared LED light has a wavelength range of 1400nm to 3000nm, and the far-infrared LED light has a wavelength range of 3000nm to 1mm. Different types of infrared LED light have different applications.
