Infrared Power LED: A Brief Overview

The infrared power LED, also known as the infrared LED, is a type of semiconductor light-emitting diode that emits infrared light. It is widely used in various fields such as consumer electronics, medical equipment, automotive, and industrial automation. In recent years, with the rapid development of technology, the infrared power LED industry has shown a strong momentum of growth. This article will introduce the infrared power LED industry, including its definition, working principle, applications, market trends, and future development prospects.

Definition and Classification of Infrared Power LED

The infrared power LED is a semiconductor device that emits infrared light with a wavelength between 700nm and 3000nm. According to the different wavelengths, infrared power LEDs can be divided into near-infrared, mid-infrared, and far-infrared. Among them, near-infrared LEDs have the shortest wavelength and are mainly used in consumer electronics and communication fields. Mid-infrared and far-infrared LEDs have longer wavelengths and are mainly used in industrial automation and medical equipment.

Working Principle of Infrared Power LED

The working principle of the infrared power LED is based on the semiconductor photoelectric effect. When the forward voltage is applied to the PN junction of the semiconductor material, electrons and holes are injected into the conduction band and valence band, respectively. Under the action of the electric field, electrons and holes recombine in the active layer, releasing energy in the form of infrared light. The intensity and color of the emitted light are determined by the energy gap of the semiconductor material.
