Infrared LED light, also known as infrared diode, is a type of semiconductor light source that emits infrared radiation. With the rapid development of technology, infrared LED lights have become widely used in various fields, such as security, medical, automotive, and consumer electronics. This article will introduce the infrared LED light industry, including its basic principles, application fields, market trends, and future development prospects.

Basic Principles of Infrared LED Light

Infrared LED light is a semiconductor device that converts electrical energy into light energy. It is composed of a semiconductor material, typically gallium arsenide (GaAs) or aluminum gallium arsenide (AlGaAs), which emits infrared radiation when electric current passes through it. The wavelength of the emitted light is typically between 780nm and 3,000nm, which is outside the visible spectrum for humans.

Types of Infrared LED Light

According to the wavelength of the emitted light, infrared LED lights can be divided into three categories: near-infrared, mid-infrared, and far-infrared. Near-infrared LED lights have a wavelength between 780nm and 1,300nm, and are commonly used in remote controls, cameras, and barcode scanners. Mid-infrared LED lights have a wavelength between 1,300nm and 3,000nm, and are mainly used in medical, automotive, and security fields. Far-infrared LED lights have a wavelength above 3,000nm, and are often used in heat lamps and infrared thermometers.
