Introduction to Infrared LED Lamp Beads

What are Infrared LED Lamp Beads?

Infrared LED lamp beads, also known as infrared diode light sources, are a type of semiconductor device that emits infrared light. They are widely used in various fields, such as consumer electronics, medical equipment, and industrial automation. Compared with traditional infrared light sources, infrared LED lamp beads have the advantages of high efficiency, long life, and small size, making them more and more popular in the market.

Working Principle of Infrared LED Lamp Beads

The working principle of infrared LED lamp beads is based on the photoelectric effect of semiconductor materials. When a forward voltage is applied to the semiconductor material, electrons and holes are generated in the material, and when they recombine, infrared light is emitted. The wavelength of the emitted light is determined by the energy band gap of the semiconductor material.

Types of Infrared LED Lamp Beads

According to the wavelength of the emitted light, infrared LED lamp beads can be divided into short-wave infrared, medium-wave infrared, and long-wave infrared. Short-wave infrared has a wavelength of 0.76-1.5μm, medium-wave infrared has a wavelength of 1.5-3μm, and long-wave infrared has a wavelength of 3-14μm. Different types of infrared LED lamp beads are suitable for different applications.
